[0001] The invention relates to a cup printing machine, and more particularly to an automatic register device for a cup printing machine.
[0002] Nowadays, cup printing machines are widely used to transfer inked images onto cups automatically. Printing quality of the cup printing machine is mainly determined by register during printing. Register refers to adjustment of printing roller with respect to a center roll, and comprises axial adjustment, circumferential adjustment, pressure adjustment, and register adjustment. Printing quality can be ensured only if accurate register is facilitated. A conventional register device comprises a printing roller, and a center roll. The printing roller is rotably disposed outside an eccentric sleeve, the eccentric sleeve is rotably disposed on a fixed shaft of the printing roller, the fixed shaft of the printing roller is fixedly disposed on the wallboard, the center roller is fixedly connected to the center shaft, and the center shaft is rotably disposed in a hole of the wallboard. 1. An axial adjustment mechanism is as follows: an axial adjustment nut is fixed on end surface of the printing roller, a bolt connects the axial adjustment nut with a sleeve of the printing roller, during adjustment, nuts on both ends are released to adjust the bolt, so that the axial adjustment nut drives the printing roller to axially move whereby facilitating axial adjustment of the printing roller with respect to the center roll. However, this adjustment mechanism can operate only after the machine is shut down, adjustment at each time cannot be quantized, appropriate register requires large amount of time, and efficiency thereof is very low. 2. A circumferential adjustment mechanism is as follows: an adjustment ring is connected to each of a sleeve of the printing roller, and the printing roller, a pair of adjustment nuts are disposed between the adjustment rings, a screw on the adjustment nut enables the adjustment rings to rotate whereby facilitating adjustment of the printing roller with respect to the center roller. This adjustment mechanism can operate after the machine is shut down, adjustment at each time cannot be quantized, appropriate register requires large amount of time, and efficiency thereof is very low. 3. A pressure adjustment mechanism is as follows: a housing of a gear box is manually toggled during adjustment, a planetary gear transmission device in the middle drives an eccentric sleeve to rotate whereby facilitating pressure adjustment between the printing roller and the center roller. However, the adjustment mechanism features complex structure and inaccurate adjustment positions, and adjustment can be performed only as the machine is shut down, which reduces efficiency thereof. 4. A register adjustment mechanism is as follows: a handle is manually toggled during adjustment, a gear transmission device in the middle drives an eccentric sleeve to rotate whereby facilitating attachment and detachment between the printing roller and the center roller, however, this adjustment mechanism features complex structure, inaccurate adjustment positions, and low efficiency.
[0003] To summarize, the conventional register device for a cup printing machine features complex structure and inaccurate adjustment positions, axial adjustment, circumferential adjustment, and pressure adjustment can be done after the machine is shut down, appropriate register requires large amount of time, efficiency thereof is very low, automatic adjustment cannot be facilitated, and grade of products is not high.
[0004] In view of the above-described problem, it is one objective of the invention to provide an automatic register device for a cup printing machine that features simple structure, accurate adjustment, and high efficiency, and is capable of facilitating fast and automatic adjustment, axial adjustment, circumferential adjustment, pressure adjustment during printing.
[0006] An automatic register device for a cup printing machine, comprising a printing roller, a roll shaft, a center roller, and a center shaft, the printing roller being flexibly fit on the roll shaft, the center roller being fixedly fit on the center shaft, the roll shaft being parallel to the center shaft, the center shaft being rotably disposed in a hole of a wallboard, and transmission connected to a power mechanism of the cup printing machine, wherein the automatic register device for a cup printing machine further comprises an axial adjustment mechanism, a circumferential adjustment mechanism, a pressure adjustment mechanism, and a fast adjustment mechanism, the axial adjustment mechanism and the circumferential adjustment mechanism are connected to the printing roller, the pressure adjustment mechanism and the fast adjustment mechanism are connected to the roll shaft, the roll shaft is an eccentric shaft, a supported end of the eccentric shaft is disposed in the hole of the wallboard, an extension end of the eccentric shaft extends from the wallboard, and the printing roller is rotably connected to the extension end of the eccentric shaft, and capable of axially sliding. Since the roll shaft uses the eccentric shaft, under the action of the pressure adjustment mechanism and the fast adjustment mechanism, a position of the printing roller disposed on the extension end of the eccentric shaft with respect to an axis of the center roller changes, and thus pressure adjustment, contact, and detachment between the printing roller and the center roller are facilitated. Moreover, since the printing roller is rotably connected to the extension end of the eccentric shaft and capable of axially sliding, under the action of the axial adjustment mechanism and the circumferential adjustment mechanism, the printing roller is capable of axially moving and circumferentially rotating on the eccentric shaft, and thus axial adjustment and circumferential adjustment of the printing roller with respect to the center roller are facilitated. During printing, rotation of the printing roller does not affect the axial adjustment mechanism, the circumferential adjustment mechanism, and the pressure adjustment mechanism, which facilitates axial adjustment, circumferential adjustment, and pressure adjustment without shutting down the register device, and the adjustment process is fast, accurate, and high efficient.
[0007] Advantageously, the axial adjustment mechanism comprises a motor and an adjustment rod, the adjustment rod is disposed in a hole of the eccentric shaft, thread is disposed on an inner shaft end of the adjustment rod, an adjustment nut is connected to the thread, and rotably disposed in a bearing seat, the bearing seat is fixed on the wallboard, the adjustment nut is transmission connected to the motor, an outer shaft end of the adjustment nut is rotably disposed in another bearing seat, and the bearing seat is connected to the printing roller. The motor is electrically connected to a potentiometer. Axial movement of the printing roller on the eccentric shaft is driven via an adjustment rod, and does not affect rotation of the printing roller during printing. Therefore, automatic axial adjustment during printing is facilitated. Moreover, the potentiometer accurately controls rotation of the motor, and thus axial adjustment is fast, accurate, and high efficient.
[0008] Advantageously, the circumferential adjustment mechanism comprises an electric adjustment device, and a helical transmission gear and a helical sun gear engaged with each other, a sliding sleeve of the electric adjustment device is disposed on an extension end of the eccentric shaft, and capable of axially sliding, the helical transmission gear is rotably disposed on excircle of the sliding sleeve, the helical transmission gear and the printing roller are transmission connected to each other via a pin, and capable of axially moving with respect to each other, and the helical sun gear is fixedly connected to the center shaft. The electric adjustment device comprises a motor, a pull rod, and the sliding sleeve, the pull rod passes through the wallboard, one end of the pull rod is connected to the sliding sleeve, thread is disposed on the other end thereof and connected to an adjustment nut, the adjustment nut is rotably disposed in the bearing seat, the bearing seat is fixed on the wallboard, and the adjustment nut is transmission connected to the motor. The motor is electrically connected to a potentiometer. Since the helical transmissions gear is rotably connected to the sliding sleeve, and the sliding sleeve is capable of axially sliding on the extension end of the eccentric shaft under the action of the electric adjustment device, the helical transmission gear is capable of axially moving on the extension end of the eccentric shaft. Since the helical transmission gear and the helical sun gear each has a helical angle, and the helical sun gear is axially fixed, the helical transmission gear rotates in a spiral-uprising direction with respect to the helical sun gear during axial movement. Thus, the helical transmission gear drives the printing roller to circumferentially rotate on the eccentric shaft via the pin, and the printing roller circumferentially moves with respect to the center roller. Circumferential adjustment of the printing roller does not affect rotation of the printing roller. Therefore, circumferential adjustment during printing is facilitated.

The motor drives the worm, the worm gear, and the eccentric shaft to rotate, and thus a position of an axis of the printing roller with respect to that of the center roller is changed, and contact pressure between the printing roller and the center roller is changed. The structure is very simple, and rotation of the printing roller does not affect pressure adjustment, and thus automatic pressure adjustment during printing is facilitated. Moreover, the potentiometer accurately controls rotation of the motor, and thus pressure adjustment is fast, accurate, and high efficient.
[0010] Advantageously, the fast adjustment mechanism comprises a gas cylinder, and a cover plate, the cover plate is connected to the supported end of the eccentric shaft, and a piston rod and a tailstock of the gas cylinder are respectively hinge connected to the cover plate and the wallboard. The gas cylinder pushes and adjusts the cover plate, so that the cover plate drives the eccentric shaft to rotate, and thus the position of the axis of the printing roller with respect to that of the center roller is changed, and contact and detachment between the printing roller and the center roller are facilitated. The structure is simple, and adjustment is fast. Moreover, since the gas cylinder only has two positions, and inaccuracy caused by manual adjustment is avoided, and thus adjustment is fast, accurate, and high efficient.
[0011] Advantageously, the motor and the gas cylinder are controlled via a touch screen. Starting of the motor and control of the gas cylinder are implemented via the touch screen, and thus automatic adjustment is facilitated, and grade of products is improved.

The bearing seat 5 is capable of axially moving along with the adjustment rod 4, and fixedly connected to the printing roller 8 via a bolt 6.
[0020] As shown in FIG. 2, the circumferential adjustment mechanism comprises an electric adjustment device, and a helical transmission gear 11 and a helical sun gear 35 engaged with each other. The electric adjustment device comprises a motor 18, a potentiometer 36, a pull rod 13, and a sliding sleeve 12. A sliding sleeve 12 of the electric adjustment device is flexibly disposed on the extension end of the eccentric shaft 7, and capable of axially sliding. The pull rod 13 passes through the wallboard 34. The right of the pull rod 13 is connected to the sliding sleeve 12. Thread is disposed on the left of the pull rod 13, and connected to an adjustment nut 14. The adjustment nut 14 is rotably disposed in a bearing seat 16. The bearing seat 16 is fixed on the wallboard 34. Gear teeth are disposed on excircle of the adjustment nut 14, and engaged with a motor gear 15 of the motor 18, and a potentiometer gear of a potentiometer 36, whereby forming transmission connection. The motor 18 and the potentiometer 36 are fixedly connected to the bearing seat 16. The motor 18 is electrically connected to the potentiometer. The potentiometer controls rotation of the motor 18. The helical transmission gear 11 is rotably disposed on excircle of the sliding sleeve 12 via a bearing 10, the helical transmission gear 11 and the printing roller 8 are transmission connected to each other via a pin 9. The left of the pin 9 is fixedly connected to the helical transmission gear 11, and the right thereof is flexibly connected to the printing roller 8. Thus, the printing roller and the helical transmission gear can rotate and axially move with respect to each other. The helical sun gear 35 is fixedly connected to the center shaft 2.
[0021] As shown in FIG. 2, the pressure adjustment mechanism comprises a worm gear 21, a worm 19, a worm base 20, a motor 37, and a potentiometer 38. The worm gear 21 is connected to a shaft end of the supported end of the eccentric shaft 7, shaft ends of the worm 19 are respectively connected to an output shaft of each of the motor 37 and the potentiometer 38, and the motor 37 is electrically connected to the potentiometer 38. The potentiometer 38 controls rotation of the motor 37, the motor 37 and the potentiometer 38 are fixedly connected to the worm base 20, and the worm base 20 is fixedly disposed on the wallboard 34.
[0022] As shown in FIG. 2, the fast adjustment mechanism comprises a gas cylinder 32, and a cover plate 30. The cover plate 30 is connected to the supported end of the eccentric shaft 7, a piston rod of the gas cylinder 32 is hinge connected to the cover plate 30 via a pin 29, and a tailstock of the gas cylinder 32 is hinge connected to the wallboard 34 via another pin 33.
[0023] The above-mentioned motors and the gas cylinder 32 are controlled via a touch screen. Starting of the motor and control of the gas cylinder 32 are implemented via the touch screen, and thus automatic adjustment is facilitated, and grade of products is improved.
[0025] After the cup printing machine is started, there is a gap between the printing roller and the center roller, if printing ink cannot be transferred to the center roller, printing cannot be facilitated. At this time, the touch screen controls one end of the gas cylinder to intake air, the piston rod of the gas cylinder extends and applies pivoting torque on the cover plate, and the cover plate rotates, then the eccentric shaft rotates along therewith, the position the axis of the extension end of the eccentric shaft is changed, and the position of the axis of the printing roller with respect to that of the center roller is changed. Thus the printing roller is contacted with the center roller, the printing ink on the printing roller is transferred to the center roller, and a printing process begins. As the printing process is to be stopped, the touch screen controls the other end of the gas cylinder to intake air, the piston rod is retracted, and the printing roller is reset. At this time, the printing roller is detached from the center roller, and the printing process is stopped. Since the gas cylinder has only two positions, attachment and detachment between the printing roller and the center roller are accurate, and fast adjustment of register is facilitated, and is accurate, which prevents inaccuracy caused by manual adjustment.
[0026] During printing of the cup printing machine, the printing roller rotates, as the position of the printing roller with respect to the center roller is to be axially adjusted, the touch screen starts the motor, the motor drives the motor gear and the adjustment nut to rotate, and the adjustment rod axially moves. The adjustment rod drives the roll shaft to axially move via the bearing seat, and movement of the roller shaft does not affect rotation of the printing roller, which facilitates axial adjustment during printing. Moreover, the potentiometer accurately controls rotation of the motor, and fast and accurate adjustment is facilitated.
[0027] As the position of the printing roller with respect to the center roller is to be circumferentially adjusted, the touch screen starts the motor, the motor drives the motor gear and the adjustment nut to rotate, and the pull rod axially moves, and drives the sliding sleeve and the helical transmission gear to axially move. Since there is a helical angle between the helical transmission gear and the helical sun gear, and the helical sun gear is axially fixed, the helical transmission gear rotates in a spiral-uprising direction with respect to the helical sun gear during axial movement. Thus, the helical transmission gear drives the printing roller to circumferentially rotate on the eccentric shaft via the pin, and the printing roller circumferentially moves with respect to the center roller. Circumferential adjustment of the printing roller does not affect rotation of the printing roller. Therefore, circumferential adjustment during printing is facilitated. Moreover, the potentiometer accurately controls rotation of the motor, and thus circumferential adjustment is fast, accurate, and high efficient.
[0028] During printing of the cup printing machine, there is pressure between the printing roller and the center roller. As the pressure is to be adjusted, the touch screen starts the motor, the motor drives the worm, the worm gear, and the eccentric shaft to rotate, and thus a position of an axis of the printing roller with respect to that of the center roller is changed, and contact pressure between the printing roller and the center roller is changed. Rotation of the printing roller does not affect pressure adjustment, and thus automatic pressure adjustment during printing is facilitated. Moreover, the potentiometer accurately controls rotation of the motor, and thus pressure adjustment is fast, accurate, and high efficient.
[0029] To summarize, the automatic register device for a cup printing machine of the invention features simple structure, accurate adjustment, and high efficiency, is capable of facilitating fast and automatic adjustment, axial adjustment, circumferential adjustment, pressure adjustment during printing, and improving grade of products, and will bring users with great convenience and active use effect.
