[0028] In a preferred embodiment, an L-shaped support frame 4 is fixed to one side wall of the support base 1. An imaging body 403, which is a CCD camera, is mounted on the top of the support frame 4. A conveyor belt 2 for transporting plastic cups is mounted on the upper end of the support base 1. A second electric push rod 401 is fixed inside the support frame 4. An arc block 402 is fixed to the telescopic end of the second electric push rod 401. The sliding assembly includes a limiting plate 502 fixed to one end of a second limiting rod 501. A sliding plate 503 for sliding the plastic cup is fixed to the inner wall of the limiting plate 502. Support rods 504 are fixed to both sides of the limiting plate 502. A baffle 505 is fixed at the top of 504. When the plastic bottles on the conveyor belt 2 are stably conveyed, they pass through the CCD camera, which quickly captures the appearance image of the plastic cups on the production line to detect whether they are defective products. The process is efficient and accurate, which can greatly improve the detection efficiency. Then, the second electric push rod 401 drives the arc block 402 to push the defective products into the slide plate 503 and convey them into the waste box 6. This realizes automated rejection, reduces labor costs, and the baffle 505 is set to ensure that the plastic cups are not subjected to large pushing force and fall outside the waste box 6 during the push, effectively preventing the defective plastic cups from scattering.

The pressure plate 602 can compress the plastic cups inside the waste box 6 via the hydraulic rod 601, significantly reducing the impact of the pressure plate. The reduced internal space occupied by the waste container 6 allows it to hold more defective plastic cups, reducing the need for frequent emptying. This results in a more compact and efficient collection of the cups, improving production efficiency and ensuring better collection. Finally, the cabinet door 603 can be opened with bolts for easy centralized cleaning. The compressed plastic cups are smaller, making them easier to transport, store, and process. Furthermore, the compression process helps improve the recycling efficiency of the plastic cups, making them easier to crush and reuse.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] During operation, the movable block 304 is first extended and retracted by the first electric push rod 303. Then, the connecting rod 306 is rotatably connected to the movable block 304 through the rotating shafts at both ends of the movable rod 305. By changing the angle of the movable rod 305, the first limiting rod 302 slides along the slide groove 3 inside the support base 1 via the slide rod 301. Then, the distance between the first limiting rod 302 and the fixed second limiting rod 501 is adjusted to limit the conveying of plastic bottles on the conveyor belt 2. When the plastic bottles on the conveyor belt 2 are stably conveyed, they pass through the CCD camera, which quickly captures the appearance image of the plastic cups on the production line to detect whether they are defective. The process is efficient and accurate, which can greatly improve the detection efficiency. Then, the second electric push rod 401 drives the arc block 402 to push the defective products into the slide plate 503 and convey them into the waste box 6, realizing automated rejection and reducing labor costs.

[0032] Finally, when the defective plastic cups enter the waste bin 6, their large size affects the usability of the waste bin 6. The pressure plate 602 can compress the plastic cups inside the waste bin 6 via the hydraulic rod 601, which can significantly reduce the space occupied inside the waste bin 6. This allows the waste bin 6 to hold more defective plastic cups, reducing the need for frequent emptying of the waste bin 6. It also makes the cups more compactly packed inside the waste bin 6, reducing gaps and ensuring more compact and efficient collection of waste. This improves production efficiency and ensures better collection of waste. Finally, the cabinet door 603 can be opened with bolts for centralized cleaning.
