A second cross bar is fixedly arranged in the feeding hopper 430, and in the initial state, the second cross bar is directly below the first cross bar, and the guide plate 420 is vertically arranged in the feeding hopper 430, and the upper end of the guide plate 420 is fixedly connected to the first cross bar, and the lower end of the guide plate 420 is rotatably connected to the second cross bar.

[0030] The water collecting mechanism 300 includes a water tank 310 and a water pipe 330. The water tank 310 is fixedly arranged on the bottom of the frame 100 and is directly below the arc filter ring 520. A filter box 320 is arranged in the water tank 310. One end of the water pipe 330 is penetrated through the filter box 320, and two water outlet pipes are horizontally arranged at the other end of the water pipe 330. The two water outlet pipes are directly above the friction member 600, and the two water outlet pipes are located on both sides of the feed hopper 430.

[0031] The sensing mechanism is used to make the first crossbar slide in the slide groove 431 when the friction member 600 moves along the axis of the arc filter ring 520, thereby making the upper end of the guide plate 420 slide along the first crossbar. The driving mechanism 200 is used to drive the friction member 600 to rotate.

[0032] In this embodiment, if Figure 1 and Figure 5 As shown, an annular groove 630 is provided on one side of the friction member 600 close to the side plate, and a first limiting hole 120 is provided on the side plate.

[0033] The sensing mechanism includes a limit block 440, a first oil cylinder 450, a first oil port 451, a second oil cylinder 710 and a second oil port 711. The limit block 440 is fixedly arranged at one end of the first cross bar, the first oil cylinder 450 is arranged horizontally, one end of the first oil cylinder 450 is fixedly connected to the support plate 410, the other end of the first oil cylinder 450 is fixedly connected to the side of the limit block 440 away from the side plate, and one end of the first oil port 451 is connected to one end of the first oil cylinder 450. The second oil cylinder 710 is arranged horizontally, one end of the second oil cylinder 710 is fixedly arranged in the first limit hole 120, the other end of the second oil cylinder 710 is inserted into the annular groove 630 through the synchronization block 712, one end of the second oil port 711 is connected to one end of the second oil cylinder 710, and the other end of the second oil port 711 is connected to the other end of the first oil port 451.

[0034] In this embodiment, if Figure 2As shown, a retaining ring is provided at the other end of the second oil cylinder 710. The sensing mechanism also includes a spring 720, which is sleeved on the second oil cylinder 710, one end of the spring 720 is fixedly connected to the retaining ring, and the other end of the spring 720 is fixedly connected to the side plate, and the spring 720 is used to reset the second oil cylinder 710.

[0035] When the materials on the left and right sides of the friction chamber are inconsistent, for example, when there is too much material on the left side of the friction chamber, the friction member 600 is squeezed by the material and moves to the left, which can avoid the blockage of the friction chamber on the left side. However, the space of the friction chamber on the left side becomes larger and the material becomes more, so the cleaning effect here will be weakened, and some materials will be easily discharged directly, resulting in inconsistent cleaning effects of the materials on both sides of the friction chamber. The leftward movement of the friction member 600 will compress the spring 720, and the hydraulic oil in the second oil cylinder 710 enters the first oil cylinder 450 through the first oil port 451 and the second oil port 711 to push the upper end of the guide plate 420 to move to the left, and the guide plate 420 deflects to the left, thereby reducing the feed on the left side of the feed hopper 430 and increasing the feed on the right side of the feed hopper 430, and finally making the amount of material on the left and right sides of the friction chamber tend to be consistent. When there is too much material on the right side of the friction chamber, the friction member 600 is squeezed by the material and moves to the right. The rightward movement of the friction member 600 stretches the spring 720, and the second oil cylinder 710 draws the hydraulic oil of the first oil cylinder 450 into the second oil cylinder 710 through the first oil port 451 and the second oil port 711, and drives the upper end of the guide plate 420 to move to the right. The guide plate 420 deflects to the right, thereby reducing the feed on the right side of the feed hopper 430 and increasing the feed on the left side of the feed hopper 430, and finally making the amount of material on the left and right sides of the friction chamber tend to be consistent. Finally, the material in the friction chamber is uniform and the cleaning effect is consistent.

[0036] In this embodiment, if Figure 2 and Figure 5 As shown, a second limiting hole 110 is provided on the side plate, and a plurality of splines 620 are provided on the inner peripheral wall of the friction member 600. The driving mechanism 200 includes a motor 210 and a transmission wheel 220. The base of the motor 210 is fixedly arranged on the side plate of the frame 100. The transmission wheel 220 is arranged in the friction member 600, and the friction member 600 can move along the axis of the transmission wheel 220. A plurality of key slots are provided on the peripheral wall of the transmission wheel 220, and the splines 620 can be slidably arranged in the key slots. The shaft of the transmission wheel 220 passes through the second limiting hole 110 and is connected to the motor 210. When the motor 210 is started, the motor 210 drives the transmission wheel 220 to rotate, and drives the friction member 600 to rotate.

[0037] In this embodiment, if Figure 1 As shown, the feeding mechanism 400 further includes a baffle, which is vertically arranged on the support plate 410, and the lower end of the baffle is arc-shaped, and the baffle is located above the friction member 600. The baffle can prevent the material from splashing when feeding.

[0038] In this embodiment, if Figure 6 As shown, a plurality of filter holes are provided on the arc filter ring 520. Sewage falls into the water tank 310 through the filter holes on the arc filter ring 520.

[0039] In this embodiment, if Figure 1 As shown, the sensing mechanism also includes a telescopic rod, which is horizontally arranged. One end of the telescopic rod is fixedly connected to a side of the limit block 440 close to the side plate, and the other end of the telescopic rod is fixedly connected to the support plate 410.

[0040] In this embodiment, if Figure 6 As shown, a particle cleaning device for plastic recycling also includes a plurality of legs 510 , which are vertically arranged on the bottom plate, and the upper ends of the legs 510 are fixedly connected to the outer peripheral wall of the arc filter ring 520 .

[0041] Working process: Figure 1 The side where the side plate is located is the left side, and the side where the discharge plate 530 is located is the front side. The material is put into the feed hopper 430 , and the feed hopper 430 passes through the guide plate 420 and falls into the friction cavity between the friction member 600 and the arc filter ring 520 .

[0042] Start the motor 210, the motor 210 drives the transmission wheel 220 to rotate clockwise from right to left, and drives the friction member 600 to rotate clockwise, the friction member 600 drives the material from the rear side of the friction chamber through the friction chamber and then from the front side of the friction chamber to the discharge plate 530, and is discharged from the discharge plate 530. The material is rubbed and kneaded by multiple friction balls 610 in the friction chamber, and the sewage falls into the water tank 310 through the filter holes on the arc filter ring 520. After the sewage is filtered by the filter box 320, it is pumped into the water pipe 330 by the water pump, and the filtered water is transported to the outlet pipe through the water pipe 330, and the water flows into the friction member 600. The water of the outlet pipe on the rear side flows into the friction chamber to rub and clean the material, and the water of the outlet pipe on the front side falls on the material after cleaning, which can clean the material again. Since the flow direction of the discharged material is different from that of the sewage and they do not interfere with each other, the discharged material is clean and will not be interfered by the sewage.

[0043] When the materials on the left and right sides of the friction chamber are inconsistent, when there is too much material on the left side of the friction chamber, the friction member 600 is squeezed by the material and moves to the left, which can avoid the blockage of the friction chamber on the left side. However, the space of the friction chamber on the left side becomes larger and the material becomes more. The cleaning effect here will be weakened, and some materials will be easily discharged directly, resulting in inconsistent cleaning effects of the materials on both sides of the friction chamber. The leftward movement of the friction member 600 will compress the spring 720, and the hydraulic oil in the second oil cylinder 710 enters the first oil cylinder 450 through the first oil port 451 and the second oil port 711 to push the upper end of the guide plate 420 to move to the left, and the guide plate 420 deflects to the left, thereby reducing the feed on the left side of the feed hopper 430 and increasing the feed on the right side of the feed hopper 430, and finally making the amount of material on the left and right sides of the friction chamber tend to be consistent. When there is too much material on the right side of the friction chamber, the friction member 600 is squeezed by the material and moves to the right. The rightward movement of the friction member 600 stretches the spring 720, and the second oil cylinder 710 draws the hydraulic oil of the first oil cylinder 450 into the second oil cylinder 710 through the first oil port 451 and the second oil port 711, and drives the upper end of the guide plate 420 to move to the right. The guide plate 420 deflects to the right, thereby reducing the feed on the right side of the feed hopper 430 and increasing the feed on the left side of the feed hopper 430, and finally making the amount of material on the left and right sides of the friction chamber tend to be consistent. Finally, the material in the friction chamber is uniform and the cleaning effect is consistent.
