DETAILED DESCRIPTION

[0037] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0038] The present application embodiment discloses a paper cup rejection mechanism. Figure 1 The rejecting mechanism includes a rejecting component 100, an extruding component 200, a material guiding component and a material collecting box 500.

[0039] The rejection assembly 100 is arranged on one side of the conveyor belt 600 for transferring paper cups. The rejection assembly 100 includes a fan 110 and an air outlet pipe 120. The fan 110 is placed on the ground. The air outlet pipe 120 is fixedly connected to the frame 610 of the conveyor belt 600. One end of the air outlet pipe 120 is connected to the air outlet end of the fan 110, and the other end extends to the side of the conveyor belt 600 away from the ground. The outlet pipe 120 is arranged to face the paper cups, so that when the fan 110 is running, wind can be blown out from the outlet pipe 120 and defective products can be rejected from the conveyor belt 600.

[0040] Reference Figure 1 and Figure 2 The extrusion assembly 200 is arranged on the side of the conveyor belt away from the rejection assembly 100. The extrusion assembly 200 includes a bracket 210, a fixed plate 220 and a movable plate 230. The bracket 210 includes a bottom plate 211 and a plurality of support legs 213. In this embodiment, four support legs 213 are provided, and one end of each of the four support legs 213 is fixedly connected to the bottom plate 211, and the other end is placed on the ground.

[0041] The fixed plate 220 is fixedly connected to the side of the bottom plate 211 facing away from the ground, the movable plate 230 is arranged parallel to the fixed plate 220 and spaced apart, and the movable plate 230 can move in a direction close to or away from the fixed plate 220, and a driving member for driving the movable plate 230 is arranged on the bottom plate 211. In this embodiment, the driving member is a driving cylinder 231, which is arranged along the moving direction of the paper cup on the conveyor belt 600, and the cylinder body of the driving cylinder 231 is fixedly connected to the bottom plate 211, and the piston rod of the driving cylinder 231 is fixedly connected to the movable plate 230.

[0042] In order to prevent defective products from falling off the bottom plate 211, two enclosing plates 2112 are fixedly connected to the bottom plate 211. The two enclosing plates 2112 are arranged in parallel and spaced apart, and the fixed plate 220 and the movable plate 230 are located between the two enclosing plates 2112, so that defective products are not easy to roll out from between the fixed plate 220 and the movable plate 230.

[0043] Reference Figure 1 and Figure 3 In order to facilitate the collection of defective products after extrusion, a drop hole 2111 is provided on the bottom plate 211. The drop hole 2111 is located on the side of the fixed plate 220 close to the movable plate 230, and along the moving direction of the movable plate 230, the size of the drop hole 2111 is smaller than the size of the defective products, so that the unextruded defective products are not easy to fall from the drop hole 2111. The movable plate 212 is located in the drop hole 2111, and a rotating shaft is fixedly connected to one side of the movable plate 212. The rotating shaft is rotatably connected to the side wall of the drop hole 2111 to open and close the drop hole 2111. The bottom plate 211 is provided with a rotating assembly 400 for driving the movable plate 212 to rotate.

[0044] The rotating assembly 400 includes a rotating gear 410, a rotating rack 420, a return spring 430 and a start block 440. Two rotating gears 410 and two rotating racks 420 are provided, one rotating rack 420 and one rotating gear 410 form a group, and the two rotating gears 410 are respectively arranged at both ends of the rotating shaft and are coaxially fixedly connected with the rotating shaft. Both rotating racks 420 are arranged along the moving direction of the movable plate 230, and are slidably connected with the bottom plate 211, and both rotating racks 420 are meshed with the rotating gear 410 of the same group. The two rotating racks 420 are fixedly connected by a connecting rod 411. One end of the return spring 430 is fixedly connected to the bottom plate 211, and the other end is fixedly connected to the connecting rod 411. Under the elastic force of the return spring 430, the movable plate 212 rotates to a position to close the blanking hole 2111. The starting block 440 is fixedly connected to the connecting rod 411 . A connecting hole 2113 is provided on the bottom plate 211 . The side of the starting block 440 away from the ground passes through the connecting hole 2113 and extends to the moving track of the moving plate 230 .

[0045] Replay Figure 1 The material guide assembly is a material guide pipe 300, which is fixedly connected to the frame 610 of the conveyor belt 600 and is mounted above the fixed plate 220 and the movable plate 230. The end of the material guide pipe 300 away from the ground corresponds to the position of the air outlet pipe 120, so that the material guide pipe 300 can receive the defective products rejected by the air outlet pipe 120. The other end of the material guide pipe 300 extends to the top of the gap between the fixed plate 220 and the movable plate 230, so that the defective products in the material guide pipe 300 can be smoothly introduced between the fixed plate 220 and the movable plate 230. In order to further enable the defective products to smoothly enter the material guide pipe 300, the end of the material guide pipe 300 away from the ground is set to be trumpet-shaped.

[0046] The implementation principle of a paper cup rejection mechanism in the embodiment of the present application is as follows: when there are defective products, the fan 110 is started to reject the defective products from the conveyor belt 600, and at the same time, the defective products move in a direction away from the fan 110, and fall between the fixed plate 220 and the movable plate 230 through the material guide tube 300, at which time the driving cylinder 231 is started to drive the movable plate 230 to move in a direction close to the fixed plate 220 and extrude the defective products into shape; after the extrusion of the defective products is completed, the driving cylinder 231 drives the movable plate 230 to move in a direction away from the fixed plate 220, and when the movable plate 230 moves to the point where it conflicts with the starting block 440, the movable plate 230 drives the starting block 440 to move and drives the rotating rack 420 to slide, and the rotating gear 410 rotates under the action of the rotating rack 420 to drive the movable plate 212 to open the drop hole 2111, and the defective products fall from the drop hole 2111 into the collecting box 500, thereby completing the collection of defective products.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
