[0024] The effect achieved by the whole embodiment 1 is that when the recycled plastic particles are put into the impurity removal box 1 through the feeding port 11, the filter screen one 5 can effectively filter the larger contaminants in the particles, when the contaminants accumulate to a certain extent, the user starts the motor 6, the motor 6 drives a rotating shaft 7 to start rotating in the movable hole 2, at this time, the sprocket 9 on one side of the outer wall of the rotating shaft 7 also rotates synchronously, and another sprocket 9 and the rotating shaft 7 are driven to rotate by the chain 10 sleeved on the surface, the two rotating rotating shafts 7 make the knocking block 8 fixedly sleeved on the outer surface wall rotate, when the protrusions of the knocking block 8 rotate to the lower side, the filter screen one 5 is pushed down and the spring 4 is extruded, when the protrusions rotate to the upper side, the extruded spring 4 starts to stretch, which makes the filter screen one 5 and the surface contaminants vibrate constantly, when the filter screen one 5 descends, the holes blocked by it begin to be exposed, the contaminants will enter the discharge port one 12 through vibration and be discharged by the discharge port one 12, the filtered particles continue to descend and are intercepted by the filter screen two 19, and the smaller contaminants will pass through the filter screen two 19 and be discharged by the discharge port two 18. The device can automatically discharge the contaminants generated during work, reducing the time and cost of manual cleaning and improving the continuity of the entire production process.

[0025] As shown in embodiment 2, Figures 2-4 The outer surface wall of the impurity removal box 1 is provided with two groups of movable holes 2, the inner surface wall of the impurity removal box 1 is fixedly installed with a group of mounting plates 3, the top of each mounting plate 3 is fixedly installed with a spring 4, the top of a group of springs 4 is fixedly installed with a filter screen one 5, the outer surface wall of the impurity removal box 1 is provided with a plurality of mounting holes one 13, the outer surface wall of the impurity removal box 1 is provided with a group of mounting holes two 14, the outer surface wall of the impurity removal box 1 is fixedly installed with a group of supporting legs 15, the inner surface wall between a plurality of mounting holes one 13 is fixedly inserted with an electromagnetic rod 16, the inner surface wall between a group of mounting holes two 14 is fixedly inserted with a screw conveyor 17, the bottom of the impurity removal box 1 is fixedly communicated with a discharge port two 18, the inner surface wall of the impurity removal box 1 is fixedly inserted with a filter screen two 19, the bottom of the filter screen two 19 is fixedly communicated with a discharge pipe 20, and the output end of the discharge pipe 20 is fixedly communicated with the input end of the screw conveyor 17, and the outer surface wall of the screw conveyor 17 is provided with a group of dust falling holes 21.

[0026] The effect achieved by the whole embodiment 2 is that after the regenerated plastic particles enter the inside of the impurity removal box 1, a group of electromagnetic rods 16 starts to be electrified, the metal impurities in the particles are attracted by the generated magnetic force, then the filter screen one 5 below can filter the relatively large pollutants in the particles, the filter screen two 19 can intercept the regenerated plastic particles, and the relatively small regenerated plastic particles are discharged from the filter screen two 19 to the outside of the impurity removal box 1, the device can make the purity of the regenerated plastic particles higher through multiple filtering methods, so as to reduce the defects and flaws in the products, improve the overall quality of the products, the regenerated plastic particles on the filter screen two 19 can enter the inside of the screw conveyor 17 through the discharge pipe 20 and be conveyed by the screw conveyor 17, automatic discharging is realized, and the remaining impurities in the regenerated plastic particles can fall again through the dust falling hole 21, and the filtering effect is further improved.

[0027] Working principle: when the regenerated plastic particles are put into the feeding port 11 of the impurity removal box 1, first, a group of electromagnetic rods 16 are electrified, the metal impurities in the particles are attracted and captured by the strong magnetic force, and it is ensured that the metal impurities are effectively removed, at the same time, the filter screen one 5 can intercept relatively large pollutants such as stone blocks and wood blocks, and further purify the plastic particles, then, the filter screen two 19 can not only intercept the regenerated plastic particles, but also allow the particles with small volume to pass through, and these screened particles are finally discharged from the impurity removal box 1 through the discharge port two 18, and the multiple filtering mechanism ensures the purity of the regenerated plastic particles, the particles on the filter screen two 19 can enter the screw conveyor 17 through the discharge pipe 20, automatic discharging is realized, and the fine impurities possibly remaining in the regenerated plastic particles can be separated again through the dust falling hole 21 in the conveying process, and the filtering effect is further improved, when the pollutants on the filter screen one 5 accumulate to a certain degree, the system can automatically start the cleaning program, the motor 6 drives the rotating shaft 7 to rotate in the movable hole 2, and simultaneously drives the sprocket 9 and the chain 10 to rotate synchronously, the knocking block 8 on the two rotating shafts 7 starts to rotate, and pushes the filter screen one 5 to descend when the convex point rotates to the lower side, and stretches the spring 4 when the convex point rotates to the upper side, so as to shake the filter screen one 5 and the pollutants on the surface, the shaking not only helps the pollutants to fall off from the filter screen one 5, but also exposes the blocked holes, so that the pollutants can enter the discharge port one 12 and be discharged through the shaking.
