(54) PUSHER FOR PLANER


(57) A pusher for a planer contains: a body (10), a planer (11), a movable control portion (20), and a push member (46). The planer (11) includes a cutter (13) and a drive shaft (14). A transmission portion (15) is formed on the body (10), and a reduction wheel (17) is connected with a horizontal rod (16). A longitudinal rod (30) is engaged with the horizontal rod (16), and a drive head (32) is formed on the longitudinal rod (30). When the cutter (13) rotates, the drive shaft (14) transmits kinetic energy to the movable control portion (20) to urge a pushing wheel (45) to rotate synchronously, and the drive shaft (14) drives the pushing wheel (45) to rotate slowly via the reduction wheel (17), hence a wood (18) is pushed slowly and is pressed and pushed by the pushing wheel (45) to be planed automatically.




Description

FIELD OF THE INVENTION



[0001] The present invention relates to a pusher for a planer which when the planner cutter rotates, the drive shaft transmits kinetic energy to the movable control portion to urge the pushing wheel to rotate synchronously, and the drive shaft drives the pushing wheel to rotate slowly via the reduction wheel, hence the wood is pushed slowly and is pressed and pushed by the pushing wheel to be planed automatically.

BACKGROUND OF THE INVENTION



[0002] A conventional planer contains a body on which a press device is arranged, and the conventional planer contains multiple idlers arranged in the press device so that when a wood is pushed through a body, it is pushed by a press force. Furthermore, the wood is pushed forward smoothly.

[0003] However, the conventional reading stand has defects as follows:
A wood is pushed by a user, but it cannot be pushed forward to be planned with an even pushing force.

[0004] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION



[0005] The primary aspect of the present invention is to provide a pusher for a planer which when the planner cutter rotates, the drive shaft transmits kinetic energy to the movable control portion to urge the pushing wheel to rotate synchronously, and the drive shaft drives the pushing wheel to rotate slowly via the reduction wheel, hence the wood is pushed slowly and is pressed and pushed by the pushing wheel to be planed automatically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS



[0007] With reference to FIGS. 1-4, a pusher for a planer according to a preferred embodiment of the present invention comprises: a body 10, a planer 11 mounted on a top of the body 10, a movable control portion 20, a push member 46 arranged on a front end of the movable control portion 20 above the planer 11; wherein the planer 11 includes a cutter 13 and a drive shaft 14 in the body 10, the drive shaft 14 extends to a lower portion of the movable control portion 20, and a transmission portion 15 formed on a rear end of the body 10, a horizontal rod 16, a reduction wheel 17 connected with the horizontal rod 16, wherein a drive head 32 is formed on a rear end of the longitudinal rod 30. A front end of the drive head 32 of the longitudinal rod 30 fitted with a rotatable block 60, wherein the rotatable block 60 includes an idler pulley 61 located above the drive head 32, and the rotatable block 60 includes an arcuate orifice 62 defined on an upper end thereof above the idler pulley 61. The drive head 32 of the longitudinal rod 30 is fitted with a first end of a lower belt 33, a second end of the lower belt 33 is fitted on a first receiving portion 35 of a transmission rod 34 above the longitudinal rod 30, and the idler pulley 61 is located inside a transmitting portion 31 and the drive head 32, an upper belt 36 is fitted on a front end of the lower belt 33, and the upper belt 36 is fitted on a wheel rod 40 and an auxiliary rod 54. The wheel rod 40 includes a second receiving portion 41 of a rear end thereof, a guiding portion 42 formed on a front end of the second receiving portion 41, a pushing wheel 45 fixed in the push member 46 of the wheel rod 40. The upper belt 36 is fitted on the second receiving portion 41, and the guiding portion 42 has a transmitting belt 43 fitted on a first end thereof. A second end of the transmitting belt 43 is fitted on an actuation rod 44 beside the wheel rod 40, the actuation rod 44 has a driving portion 47 formed on a rear end thereof so as to fit with the transmitting belt 43, and the actuation rod 44 has another pushing wheel 45 connected with the push member 46.

[0008] The auxiliary rod 54 is supported on an auxiliary abutting block 50 inserted onto a positioning rod 52 which is mounted on a base 51, and a returning spring 53 is fitted on the positioning rod 52 between the base 51 and the auxiliary abutting block 50.

[0009] Furthermore, the movable control portion 20 includes a rotary shaft 21 mounted on an upper end of the movable control portion 20 and extending to the movable control portion 20 inwardly. The movable control portion 20 includes a movable pedestal 22 connected with the wheel rod 40.

[0010] Referring to FIGS. 4-6, the rotatable block 60 rotates along the longitudinal rod 30, a locking portion 63 is arranged on the body 10 inside of the arcuate orifice 62 so that after the lower belt 33 is fitted with the drive head 32 of the longitudinal rod 30 and the first receiving portion 35 of the transmission rod 34 to control the rotatable block 60 to rotate, and the idler pulley 61 of the rotatable block 60 abuts against the lower belt 33 outward, and the rotatable block 60 is locked with the locking portion 63 by ways of a screw bolt. Thereby, the lower belt 33 is tightened, released, fixed, and detached easily by ways of the rotatable block 60 and the idler pulley 61 easily.

[0011] Referring to FIGS. 4-7, after controlling the rotary shaft 21 of the movable control portion 20, the movable pedestal 22 of the movable control portion 20 lifts and descends, and the auxiliary abutting block 50 is pushed upward by the returning spring 53, such that when the push member 46 is pushed to any heights, the upper belt 36 is tightened.

[0012] Accordingly, when the planer operates, a wood 18 is pushed to the planer 11 from a platform 12, the wood 18 contacts with the pushing wheel 45 of the push member 46, and a user rotates the rotary shaft 21 to control the pushing wheel 45 to press the wood 18. When the cutter 13 rotates, the drive shaft 14 transmits kinetic energy to the movable control portion 20 to urge the pushing wheel 45 to rotate synchronously, and the drive shaft 14 drives the pushing wheel 45 to rotate slowly via the reduction wheel 17, thus pushing the wood 18 slowly. The wood 18 is pressed and pushed by the pushing wheel 45 to be planed automatically.

[0013] While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
