Description

Technical Field

[0001] This utility model relates to the field of disposable plastic cup production technology, and in particular to a waste collection device for plastic cup production. Background Technology

[0002] In the production of plastic cups, injection molding is one of the common processing methods. Molten plastic is injected into a mold and cooled to form a plastic cup. However, during the demolding process, excess waste often remains on the edge of the plastic cup. This waste not only affects the appearance and quality of the product, but may also cause inconvenience to subsequent packaging and use. Therefore, waste removal and collection devices are usually required on plastic cup production lines to ensure that the edges of the product are smooth and to avoid waste from polluting the production environment.

[0003] Currently, a waste collection device for the production of disposable plastic cups is disclosed in publication number CN218803595U. The device includes a collection box, a mold core, and a mold shell. It achieves waste cutting and collection by setting a cutting mechanism and a sealing mechanism. The device uses a ring cutter and a cylinder to cut the waste and uses a spring-supported sealing plate to open and close the collection box. However, in actual use, the sealing plate relies on the spring to reset. Long-term use can easily lead to elastic failure, affecting the opening and closing of the collection box and preventing waste from entering the collection box.

[0004] Therefore, it is necessary to provide a new waste collection device for plastic cup production to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a waste collection device for the production of plastic cups.

[0006] This utility model provides a waste collection device for plastic cup production, comprising: a collection box and a mold shell. The top of the collection box is provided with an opening and closing mechanism, a cutting mechanism, and a synchronization mechanism. A groove is provided on one side of the top of the collection box. The cutting mechanism is sleeved on the outside of the mold shell. The opening and closing mechanism is fixed inside the collection box. The opening and closing mechanism and the cutting mechanism move synchronously through the synchronization mechanism. The synchronization mechanism includes a drive mechanism, a sliding block, and a sliding rod. The output end of the telescopic mechanism is connected to the sliding block. The sliding block slides in the groove. A second groove is provided on the top of the sliding block. One end of the sliding rod slides in the second groove. The bottom of the sliding block is connected to the input end of the opening and closing mechanism. The other end of the sliding rod is connected to the input end of the cutting mechanism. When the sliding block slides in the groove, the opening and closing mechanism performs an opening and closing movement. At the same time, when the sliding rod slides in the second groove, the cutting mechanism performs a lifting and lowering movement inside the collection box.

[0007] Preferably, the telescopic mechanism includes a motor and a telescopic rod, one end of the telescopic rod is fixedly connected to the motor, and the other end of the telescopic rod is fixedly connected to a sliding block.

[0008] Preferably, the opening and closing mechanism includes a rack, a first gear, a second gear, and an arc-shaped block. One side of the rack is fixedly connected to the bottom of the sliding block. The two sides of the first gear mesh with the second gear and the rack, respectively. The center ring of the second gear is provided with multiple arc-shaped blocks.

[0009] Preferably, the cutting mechanism includes an annular plate, a sliding plate, and an annular cutter. A fixed plate is provided on the other side of the top of the collection box, and a slide rail is provided on the fixed plate. The top of the annular cutter is fixedly connected to the bottom of the annular plate, one end of the annular plate is fixedly connected to a slide rod, and the other side of the annular plate slides along the slide rail.

[0010] Preferably, the top of the collection box is also provided with an annular groove, and a support column is provided in the annular groove.

[0011] Preferably, the axis of the support column coincides with the central axis of the mold shell, and the annular cutter is sleeved on the outside of the mold shell.

[0012] Compared with related technologies, the waste collection device for plastic cup production provided by this utility model has the following advantages: By setting a synchronization mechanism, the opening and closing mechanism and the cutting mechanism can move in tandem, ensuring the synchronization of waste cutting and the opening and closing of the collection box. When the sliding block slides in the groove, the opening and closing mechanism moves in an opening and closing motion, while the sliding rod drives the cutting mechanism to rise and fall. This linkage method not only avoids waste from getting stuck at the top of the collection box due to spring failure, preventing waste from entering the collection box, but also ensures the reliability of the device for long-term use.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of a waste collection device for plastic cup production provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the synchronization mechanism. Figure 3 for Figure 1 The diagram shows the structure of the opening and closing mechanism.

[0017] In the specific implementation process, such as Figures 1-3 As shown, a waste collection device for plastic cup production includes a fixed base 23, a collection box 1, and a mold shell 2. The collection box 1 is fixedly installed on the fixed base 23. Four support rods 25 are vertically arranged at the four corners of the fixed base 23. The top of the support rods 25 is fixedly connected to a top plate 24 to form a stable frame structure. A drive motor 11 is fixedly installed at the center of the top plate 24. The drive motor 11 drives the mold shell 2 to rise and fall.

[0018] The top of the collection box 1 is equipped with an opening and closing mechanism 3, a cutting mechanism 4, and a synchronization mechanism 5. A groove 6 is provided on one side of the top of the collection box 1. The cutting mechanism 4 is fitted onto the outside of the mold shell 2. The opening and closing mechanism 3 is fixed inside the collection box 1. The opening and closing mechanism 3 and the cutting mechanism 4 move synchronously through the synchronization mechanism 5. The synchronization mechanism 5 includes a telescopic mechanism 7, a sliding block 8, and a sliding rod 9. The telescopic mechanism 7 includes a motor 11 and a telescopic rod 12. One end of the telescopic rod 12 is fixedly connected to the motor 11, and the other end is fixedly connected to the sliding block 8. The sliding block 8 slides within the groove 6, which defines the movement trajectory of the sliding block 8. A second groove 10 is provided on the top of the sliding block 8, and one end of the sliding rod 9 is located within the groove. The sliding block 8 slides within the groove 10. The bottom of the sliding block 8 is connected to the input end of the opening and closing mechanism 3, and the other end of the sliding rod 9 is connected to the input end of the cutting mechanism 4. When the sliding block 8 slides within the groove 10, the opening and closing mechanism 3 performs an opening and closing motion. At the same time, when the sliding rod 9 slides within the groove 10, the cutting mechanism 4 performs a lifting and lowering motion within the collection box 1. By setting a synchronization mechanism 5, the opening and closing mechanism 3 and the cutting mechanism 4 can achieve linkage motion, ensuring the synchronicity of waste cutting and the opening and closing of the collection box 1. When the sliding block 8 slides within the groove 16, the opening and closing mechanism 3 performs an opening and closing motion, and at the same time, the sliding rod 9 drives the cutting mechanism 4 to lift and lower, avoiding waste from getting stuck in the gap and improving the smoothness and efficiency of waste collection.

[0019] The opening and closing mechanism 3 includes a rack 13, a first gear 14, a second gear 15, and an arc-shaped block 16. One side of the rack 13 is fixedly connected to the bottom of the sliding block 8. The two sides of the first gear 14 are respectively meshed with the second gear 15 and the rack 13. The center of the second gear 15 is provided with multiple arc-shaped blocks 16. The rack 13 moves with the sliding block 8, driving the first gear 14 that meshes with it to rotate. The first gear 14 drives the second gear 15 to rotate, causing the multiple arc-shaped blocks 16 in the center of the second gear 15 to unfold outward.

[0020] The cutting mechanism 4 includes an annular plate 17, a sliding plate, and an annular cutter 18. A fixed plate 21 is provided on the other side of the top of the collection box 1. A slide rail 22 is provided on the fixed plate 21. The top of the annular cutter 18 is fixedly connected to the bottom of the annular plate 17. One end of the annular plate 17 is fixedly connected to the slide rod 9. The other side of the annular plate 17 slides along the slide rail 22. The slide rail 22 ensures that the annular plate 17 rises and falls smoothly. The slide rod 9 in the groove 10 at the top of the sliding block 8 slides with the sliding block 8. The slide rod 9 pushes the annular plate 17 to move downward along the slide rail 22 on the fixed plate 21, which drives the annular cutter 18 to fall synchronously. The annular cutter 18 is sleeved on the mold shell 2 and moves downward to cut off the waste material on the edge of the plastic cup. After the waste material is cut off, it falls into the open collection box 1 under the action of gravity.

[0021] When the arc-shaped block 16 is fully extended, the annular cutter 18 reaches the lowest cutting position. When the arc-shaped block 16 is fully closed, the annular cutter 18 is fully retracted. The top of the collection box 1 is also provided with an annular groove 19, and a support column 20 is provided in the annular groove 19. The axis of the support column 20 coincides with the central axis of the mold shell 2. The annular cutter 18 surrounds the outside of the mold shell 2. The support column 20 is used to support the mold shell 2 and prevent it from entering the collection box 1.

[0022] The working principle provided by this utility model is as follows: In the initial state, the opening and closing mechanism 3 is in the closed state, sealing the top opening of the collection box 1. The annular cutter 18 of the cutting mechanism 4 is in the initial position above the mold shell 2. When it is necessary to collect waste, the telescopic mechanism 7 is activated, which drives the telescopic rod 12 to extend. The telescopic rod 12 pushes the sliding block 8 to slide outward along the groove 6 at the top of the collection box 1. The rack 13 at the bottom of the sliding block 8 moves with the sliding block 8, driving the gear 14 meshing with it to rotate. The gear 14 drives the gear 2 15 to rotate, causing the multiple arc-shaped blocks 16 arranged in the center of the gear 2 15 to unfold outward, thereby opening the top opening of the collection box 1. The sliding rod 9 in the groove 2 10 at the top of the sliding block 8 slides with the sliding block 8. The sliding rod 9 pushes the annular plate 17 along the fixed plate 21. The slide rail 22 moves downward, causing the annular cutter 18 to descend synchronously. The annular cutter 18 moves downward around the mold shell 2, cutting off the waste material on the edge of the plastic cup. After the waste material is cut off, it falls into the open collection box 1 under the action of gravity. Then, the drive mechanism reverses, the telescopic rod 12 retracts, causing the sliding block 8 to move in the opposite direction. The rack 13 drives the gear mechanism to reverse, causing the arc block 16 to retract inward, closing the opening of the collection box 1. The slide rod 9 drives the annular plate 17 to move upward, causing the annular cutter 18 to return to the initial position. Throughout the process, the opening and closing action of the opening and closing mechanism 3 and the lifting and lowering movement of the cutting mechanism 4 are completely synchronized through the synchronization mechanism 5, ensuring that the waste material can immediately enter the collection box 1 after being cut off, and that the opening of the collection box 1 can be closed in time to prevent the waste material from scattering.

[0023] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
