Description

BACKGROUND

Technical Field

[0001] The present invention relates to the field of canned product processing technology, and specifically, to a continuous filling and rapid canning system for powder materials.

Related Art

[0002] An existing filling apparatus for canned products usually includes a disc-shaped rotary base located between an inlet conveyor line and an outlet conveyor line. A plurality of circumferentially arranged can placement positions are provided on the rotary base. A fixed discharging and filling mechanism (for example, a spiral discharging mechanism) is disposed at a specific position above the rotary base. In a working process of the filling apparatus for canned products, empty cans fed from the inlet conveyor line are transferred by an entry mechanism to the rotary base, and then move along with the rotation of the rotary base below the filling mechanism for filling. After the filling ends, the filled cans move along with the rotation of the rotary base to the side of the outlet conveyor line and are transferred by an exit mechanism to the outlet conveyor line for output.

[0003] The inventor finds in research that conventional continuous filling apparatuses for canned products at least have the following disadvantages:

First, because the filling mechanism is fixed on a specific station, and when each empty can reaches the filling station, the rotary base needs to stop for a period of time to wait for filling to end, the entire filling period is relatively long, affecting the packaging efficiency.

Second, in the conventional filling structure, after filling ends, before entering the outlet conveyor line, a can is usually weighed by a disposed weighing apparatus to examine whether the filling amount is qualified. If it is found out that the filling amount is insufficient, it is impossible to make an addition but is only possible to discard the unqualified product, causing a waste to the production capability.

Third, manual labor is used to make weight adjustment. As a result, the probability of product contamination is increased, much time and labor are required, and costs are increased.

Embodiment

[0024] Referring to FIG. 1 to FIG. 4, this embodiment provides a continuous filling and rapid canning system for powder materials and is applicable to filling milk powder in an iron can.

[0025] The continuous filling and rapid canning system for powder materials provided in this embodiment includes a frame 002, a feed unit 100, a rotary filling unit 200, a can body input unit 300, and a can body output unit 400. The feed unit 100 includes an annular feed groove 110 and a feed pipe 120. At least two feed ports 111 are provided in the annular feed groove 110. An end of the feed pipe 120 extends into the annular feed groove 110. The rotary filling unit 200 includes a drive element 210, a rotary base 220, a rotary disc 230, and a filling assembly 240. The drive element 210 is mounted on the frame 002. The rotary base 220 and the rotary disc 230 are both mounted on the drive element 210. The rotary base 220 and the rotary disc 230 are disposed at an interval. The rotary disc 230 is far away from the drive element 210. At least two filling stations are disposed on the rotary base 220. The feed pipe 120 is mounted on an outer ring of the rotary disc 230. The filling stations correspond one-to-one to the feed ports 111. Each filling station is connected to the corresponding feed port 111 by one filling assembly 240. The can body input unit 300 and the can body output unit 400 are both mounted on the frame 002. The can body input unit 300 is used for conveying can bodies 001 onto the filling stations. The can body output unit 400 is used for moving the filled can bodies 001 away from the filling stations.

[0026] For the continuous filling and rapid canning system for powder materials provided in this embodiment, in a filling process, a material enters the annular feed groove 110 from the feed pipe 120. The material in the annular feed groove 110 is conveyed by the filling assemblies 240. Before filling, empty cans are conveyed by the can body input unit 300 onto the rotary base 220. In a rotation process of the rotary base 220, the empty cans sequentially enter the filling stations on the rotary base 220. In a process that the empty cans enter the filling stations and rotate along with the rotary base 220, the material is conveyed by the filling assemblies 240 into the empty cans located on the rotary base 220. The positions of the filling assemblies 240 correspond one-to-one to the positions of the empty cans. The filling assemblies 240 are located on the rotary disc 230 and rotate synchronously with the rotary base 220. That is, the filling assemblies 240 and the empty cans rotate together, and the filling of the material is completed in the rotation process. After the filling of the material is completed, the can bodies 001 are outputted by the can body output unit 400. The filling stations are reserved for the addition of new empty cans, and this cycle is repeated. In addition, in the filling process, the material continuously enters the annular feed groove 110 from the feed pipe 120. In this process, the feed pipe 120 is stationary. The annular feed groove 110 rotates to implement the addition of the material. The material can be rapidly and uniformly filled in the annular feed groove 110. Because the annular feed groove 110 is disposed at the outer ring of the rotary disc 230 and the feed pipe 120 is located on the outer side of the rotary disc 230, the cleaning is convenient, interference is not likely to occur with other parts, and maintenance and mounting are convenient. In addition, one feed pipe 120 is used to convey the material, and only one metal detector needs to be mounted on the feed pipe 120, so that the number of metal detectors is reduced, and costs are reduced.

[0027] It needs to be noted that the number of the feed port 111 is set as required. For example, 12 feed ports 111 may be disposed. Optionally, one feed pipe 120 is disposed.

[0028] It needs to be noted that, the drive element 210 may be an electric motor. The rotary base 220 and the rotary disc 230 are coaxially disposed.

[0029] Optionally, the at least two feed ports 111 are arranged at a uniform interval around a rotating shaft of the drive element 210. Each feed port 111 is approximately a strip-shaped port. A length direction of the feed port 111 extends in a length direction of the annular feed groove 110. With such a structural design, the feed port 111 has a larger area, making it convenient for the material to enter the filling assemblies 240 from the feed port 111 for filling.

[0030] Further, a material guide structure is disposed between adjacent feed ports 111. The material guide structure is disposed, so that when the material is conveyed by the feed pipe 120 to enter the annular feed groove 110, the material does not accumulate at the groove bottom of the annular feed groove 110, to avoid a case that the material accumulates to cause the lumping of the material, thereby reducing a waste of the material and facilitating the cleaning of the annular feed groove 110.

[0031] Optionally, the material guide structure is a material guide taper. For example, the material guide structure is a cone.

[0032] It should be understood that to reduce the accumulation of the material in the annular feed groove 110, another structure may be used. For example, in other embodiments, the feed port 111 includes a first edge close to a groove opening of the annular feed groove 110 and a second edge away from the groove opening of the annular feed groove 110. A hole diameter of the feed port 111 gradually decreases from the first edge to the second edge in an axial direction of the feed port 111. The first edges of adjacent feed ports 111 are connected.

[0033] In this embodiment, the filling assembly 240 includes a housing 241, a motor 242, and a spiral feeding rod 243. The motor 242 is mounted on the rotary disc 230. The motor 242 is located on an inner side of the annular feed groove 110. The housing 241 is mounted on the rotary disc 230. The spiral feeding rod 243 is mounted on an output shaft of the motor 242. The spiral feeding rod 243 is located in the housing 241. One end port of the housing 241 is in communication with the feed port 111, and the other end port of the housing 241 is located above the filling station, to make the material fall into a can body 001 located on the filling station. The material that enters the housing 241 from the feed port 111 is pressed by the rotation of the spiral feeding rod 243 to fall from a bottom end port of the housing 241 to enter the empty cans. The housing 241 may be a cylinder.

[0034] It needs to be noted that, the number of the feed ports is equal to the number of the spiral feeding rods for filling the material.

[0035] In this embodiment, one weighing unit 500 is further mounted on each filling station. The weighing unit 500 may be an electronic scale. An empty can is located above the weighing unit 500. The weighing unit 500 can perform real-time detection to obtain the weight of a can body 001, to further facilitate the control of the filling amount of the material filled by the filling assembly 240 into the empty can, to implement more accurate control.

[0036] In this embodiment, the can body input unit 300 includes a spiral convey assembly, and the can body output unit 400 includes a spiral convey assembly. A guide chuck 003 is mounted between an inlet and an outlet of the rotary base 220. An input rotary clamp member 004 is mounted at the inlet of the rotary base 220. A first toggle clamp groove 005 is disposed on the input rotary clamp member 004. An output rotary clamp member 006 is mounted at the outlet of the rotary base 220, and a second toggle clamp groove 007 is disposed on the output rotary clamp member 006. During working, can bodies 001 inputted by a conveyor unit of the can bodies 001 enter the first toggle clamp groove 005 of the input rotary clamp member 004. The input rotary clamp member 004 then rotates to enable the empty cans to slide along the guide chuck 003 to enter the filling stations on the rotary base 220. After the filling is completed, under the rotation of the output rotary clamp member 006, the can bodies 001 enter the second toggle clamp groove 007, and the can bodies 001 are pushed to enter the guide chuck 003 and slide along the guide chuck 003 to enter the can body output unit 400 to be outputted by the can body output unit.

[0037] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. For persons skilled in the art, various changes and variations may be made to the present invention. Any modification, equivalent replacement and improvement made within the spirit and rule of the present invention shall be also included in the scope of protection of the present invention.
