At this time, the driving mechanism drives the receiving platform to rise to be level with the conveyor belt, and then the plastic placement frame is transported to the top of the receiving platform through the cooperation of the transmission mechanism. After being transported to the right position, the driving mechanism drives the receiving platform to descend until the surface of the transmission gear and the rack are meshed, and then the plastic is rinsed through the nozzle. During the rinse, the rack is driven back and forth by the driving cylinder, driving the transmission gear to rotate back and forth and driving the toggle plate to rotate through the connecting shaft, so as to toggle and clean the plastic particles, and the cleaning effect is better. After the cleaning is completed, the receiving platform is driven to rise by the driving mechanism, and then the plastic placement frame is output through the cooperation of the transmission mechanism and the conveyor belt, and then a new batch of processing is carried out. The processing is convenient and does not require manual operation. Water resources can be reused, and the plastic can be fully and accurately cleaned without affecting the quality of the recycled plastic particles. The discharging operation is convenient. Through the setting of the plastic placement frame, the plastic can be effectively loaded to prevent it from floating above the water surface.

At this time, the driving mechanism drives the receiving platform to rise to the level with the conveyor belt, and the motor drives the driving wheel to rotate. The driving wheel rotates to drive the pull rope to move up and down, driving the receiving platform to move up and down in the cleaning box, which is used to drive the plastic placement frame to sink into or rise above the water surface, and then the plastic placement frame is transported to the top of the receiving platform through the cooperation of the transmission mechanism. After being transported to the right place, the driving mechanism drives the receiving platform to descend until the transmission gear engages with the surface of the rack, and then the plastic is rinsed through the nozzle. During rinsing, the rack is driven back and forth by the driving cylinder, driving the transmission gear to rotate back and forth and driving the toggle plate to rotate through the connecting shaft, so as to toggle and clean the plastic particles, and the cleaning effect is better. After cleaning, the driving mechanism drives the receiving platform to The platform rises, and then the plastic placement frame is output through the cooperation of the transmission mechanism and the conveyor belt, and then a new batch of processing is carried out. The processing is convenient and does not require manual operation. Water resources can be reused, and the plastic can be comprehensively and accurately cleaned without affecting the quality of the recycled plastic particles. The discharging operation is convenient. Through the setting of the plastic placement frame, the plastic can be effectively loaded to prevent it from floating on the water surface. The water flow in the cleaning box is driven by the circulation spoiler to disturb the water flow to form a cycle. The circulating water flow is pushed by the circulation spoiler and filtered through the filter screen cover before circulation. When in use, the residue accumulates on one side of the filter screen cover. After too much accumulation, the circulation spoiler scrapes the residue out to the bottom of the baffle plate and accumulates in the slag discharge channel, which effectively prevents the filter screen cover from being blocked. Filtering can be carried out continuously, and the dirt can be quickly discharged under water pressure by opening the solenoid valve of the slag discharge channel.

Through the setting of the plastic placement frame, the plastic can be effectively loaded to prevent it from floating above the water surface.

[0015] 2. The present invention drives the water flow disturbance in the cleaning box through the circulation spoiler to form a circulation. The circulating water flow is pushed by the circulation spoiler and then filtered through the filter screen cover for circulation. When in use, residues accumulate on one side of the filter screen cover. After excessive accumulation, the circulation spoiler scrapes the residues under the shielding plate and accumulates in the residue discharge channel, which effectively prevents the filter screen cover from being blocked, allows continuous filtering, and can quickly discharge dirt under water pressure by opening the solenoid valve of the residue discharge channel.
