Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to an intermittent adsorption-type feeding mechanism for a dust cover of a can. Background Technology

[0002] In the secondary storage of canned milk powder, the dust cover, which can be resealed, plays a crucial role. These dust covers can be made in both round and square shapes and are widely used in the food industry, such as for pet food, canned nuts, potato chips, eight-treasure porridge, and milk powder packaging. Current technology primarily uses a dust cover capping machine to complete the capping process. Currently, capping machines typically use a dust cover conveyor belt to transport the dust covers to the capping mechanism. The continuous conveying of the dust cover conveyor belt enables continuous capping operations. This belt conveyor method requires the dust covers to be continuously fed onto the conveyor belt. Currently, the dust covers are usually fed onto the conveyor belt by automatically sliding off from a material support. This method suffers from the problem of dust covers easily stacking and clogging, frequently requiring machine downtime for maintenance, which affects the high-efficiency continuous production line and needs improvement. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an intermittent adsorption-type feeding mechanism for a tank dust cover.

[0004] The technical solution of this utility model is: an intermittent adsorption-type feeding mechanism for a tank dust cover, comprising a circular support and several limiting components evenly distributed in the inner ring of the circular support. The limiting components include a stop bar arranged along the generatrix of the circular support and a finger-shaped baffle connected to the lower end of the stop bar. The baffle is a cylindrical rod with a guide tip at its upper end. The lower end of the finger-shaped baffle is an inwardly inclined plate end. Two vertical support plates are evenly distributed on the outer side of the circular support. A sliding groove plate is connected between the middle of the two vertical support plates. An adsorption through hole is provided in the middle of the sliding groove plate. The adsorption through hole is an oblong hole. A horizontal support plate is provided between the lower ends of the two vertical support plates. A cylinder is installed in the middle of the horizontal support plate. The piston rod of the cylinder extends upward from the through hole in the middle of the horizontal support rod. A U-shaped support is connected to the upper end of the piston rod of the cylinder. A suction cup assembly corresponding to the adsorption through hole is installed on the upper part of the U-shaped support. The suction cup assembly is coaxially arranged with the piston rod.

[0005] Preferably, the lower end of the stop bar has an assembly plane on its outer side, and both ends of the assembly plane have threaded blind holes. A bolt rod is vertically connected in the threaded blind hole at the upper part of the assembly plane. The upper end of the finger baffle has a sleeve hole that fits onto the bolt rod, allowing it to slide along the bolt rod with a certain amount of swinging allowance. A pressure spring is fitted on the bolt rod to press down on the finger baffle.

[0006] Preferably, a long guide rod is vertically connected in the threaded blind hole at the lower part of the assembly plane, and a long hole is provided in the middle of the finger baffle to fit on the long guide rod. A limit nut is threadedly connected to the upper end of the long guide rod, and a downward pressure spring B is provided in the middle of the long guide rod. After the height is adjusted by turning the limit nut, the clamping force of the downward pressure spring B can be adjusted, thereby adjusting the elastic pressure received by the finger baffle.

[0007] Preferably, the stop bar is connected to the annular bracket via a radial plate. An adjustment elongated hole is provided in the middle of the radial plate along its length direction. The two ends of the adjustment elongated hole are close to the two ends of the radial plate. Screws that are threadedly connected to the annular bracket are provided in the adjustment elongated hole.

[0008] Preferably, the lower part of the vertical support plate is provided with a vertical elongated hole along its length direction, and a screw B that is threadedly connected to the end face of the horizontal support plate is provided in the vertical elongated hole. The vertical elongated hole is arranged in two rows, corresponding to the two ends of the end face of the horizontal support plate respectively.

[0009] Preferably, the circular bracket has a docking support on one side, and the length of the stop bar on the side closer to the docking support is greater than the length of the stop bar on the other side. The feeding mechanism is in an inclined state when in use, and this arrangement of the stop bars can accommodate more dust covers.

[0010] The beneficial technical effects of this utility model are as follows: The feeding mechanism uses several baffles on the circular support to place the dust cover, and uses finger-shaped baffles with elastic force at the lower end of the baffles to hold the dust cover. Therefore, the suction cup assembly at the upper end of the cylinder can pull the dust cover downward to overcome the elastic resistance and pull it out from between the baffles to release it onto the slide plate. This method of sequential suction feeding can effectively avoid the problem of dust cover stacking, ensure that they slide down in an orderly manner, and improve the operating efficiency of the production line.

[0017] Example 1, see appendix Figure 1-2 A tank dust cover intermittent adsorption-type feeding mechanism includes a circular support 1 and several limiting components evenly distributed in the inner ring of the circular support. Each limiting component includes a stop bar 21 arranged along the generatrix of the circular support 1 and a finger-shaped baffle 22 connected to the lower end of the stop bar. The lower end of the finger-shaped baffle is an inwardly inclined plate end 23 that extends between each stop bar 21, blocking the dust cover placed between each stop bar 21. Two vertical support plates 3 are evenly distributed on the outer side of the circular support 1, and a sliding groove plate 31 is connected between the middle of the two vertical support plates. The sliding groove plate is inclined... The dust cover can automatically slide down the slide plate when it falls. The slide plate 31 has an adsorption hole 32 in the middle. A horizontal support plate 33 is provided between the lower ends of the two vertical support plates 3. A cylinder 34 is installed in the middle of the horizontal support plate. A U-shaped bracket 35 is connected to the upper end of the piston rod of the cylinder 34. A suction cup assembly 36 corresponding to the adsorption hole 32 is installed on the upper part of the U-shaped bracket. The size of the adsorption hole 32 is larger than the size of the suction cup assembly 36. A docking support 5 is provided on one side of the annular bracket 1. The length of the stop bar 21 on the side near the docking support is greater than the length of the stop bar 21 on the other side.

[0018] In this embodiment, the feeding mechanism uses several baffles 21 on the annular support 1 to hold the dust cover, and uses finger-shaped baffles 22 with elastic force at the lower end of the baffles 21 to hold the dust cover. The suction cup assembly 36 at the upper end of the cylinder 34 sucks the dust cover and pulls it down so that it can overcome the elastic resistance and pull it out from between the baffles 21 and drop it onto the slide plate 31, and then slide down from the slide plate 31.

[0019] Example 2, see appendix Figure 4-5This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the outer side of the lower end of the stop rod 21 is provided with an assembly plane, and the upper part of the assembly plane is vertically connected to the bolt rod 24. The upper end of the finger baffle 22 is provided with a sleeve hole 25 that fits into the bolt rod 24. The size of the sleeve hole 25 is larger than the size of the bolt rod 24. A downward pressure spring A 26 is fitted on the bolt rod 24 to press down the finger baffle 22. The finger baffle 22 is pressed by the downward pressure spring, so that the inner end of the finger baffle can extend into the inner ring of the ring bracket 1 to block the sealing cover.

[0020] A long guide rod 27 is vertically connected to the lower part of the assembly plane. The middle part of the finger baffle 22 is provided with a long hole 28 that fits on the long guide rod 27. The upper end of the long guide rod is threaded with a limit nut 29. The middle part of the long guide rod 27 is provided with a downward pressure spring 30. The downward pressure spring 30 assists the downward pressure spring 26 to provide strong elastic support for the finger baffle 22, thereby enabling it to hold more dust covers and increase the capacity of the feeding mechanism.

[0021] When the feeding mechanism of this embodiment is working, dust covers are stacked between each baffle 21. The inclined plate end 23 of the lower end of the finger baffle 22 provided at the lower end of each baffle 21 can hold the edge of the bottom dust cover, thereby limiting the position of the dust cover. Then, the cylinder 34 is activated, and the cylinder 34 moves the suction cup assembly 36 upward. After the suction cup assembly 36 passes through the suction hole 32, it is firmly attached to the inner surface of the dust cover. Then, the cylinder 34 drives the suction cup assembly 36 to move the dust cover downward. When the downward pulling force is greater than the elastic resistance of the dust cover, the finger baffle 22 compresses the spring and swings outward. The dust cover is pulled out from between each finger baffle 22 by the suction cup assembly 36. Then, the suction cup assembly 36 releases it and drops it onto the slide plate 31. This method of sequential suction feeding can effectively avoid the problem of dust cover stacking and improve the stability and efficiency of feeding.

[0022] Example 3 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the stop bar 21 is connected to the annular bracket 1 through the radial plate 41. An adjustment elongated hole 42 is provided in the middle of the radial plate 41 along its length direction. A screw a 43 is provided in the adjustment elongated hole and is threadedly connected to the annular bracket 1. After loosening the screw a 43, the radial plate 41 can be adjusted in position along the radial direction of the annular bracket 1 to accommodate and store dust covers of different diameters.

[0023] The lower part of the vertical support plate 3 has a vertically elongated hole 44 along its length. A screw B 45 is provided in the vertically elongated hole and is threaded to the end face of the horizontal support plate 33. After the screw B is loosened, the horizontal support plate 33 can be vertically adjusted between the vertical support plates 3, thereby adjusting the height of the cylinder 34 and the suction cup assembly 36, ensuring that the suction cup assembly 36 can be firmly attached to the bottom surface of the dust cover.
