[0027] In one embodiment of the utility model, the side wall of the filter box 3 is fixedly connected with a feeding device 4, and the feeding device 4 is arranged at one end of the filter box 3 away from the guide plate 6. The inner wall of the filter box 3 is hinged with a movable plate 5, and the top end surface of the movable plate 5 is provided with a filter hole 7. The side wall of the filter box 3 is provided with an opening, and the inner bottom of the opening is fixedly connected with a guide plate 6, and the top end surface of the guide plate 6 abuts against the movable plate 5. The inner wall of the filter box 3 is fixedly connected with a filter plate 8, and the filter hole 7 is arranged on the side of the movable plate 5 close to the filter plate 8. Resin particles fall onto the filter plate 8 through the filter hole 7, while large impurities pass through the guide plate 5. The guide plate 6 is discharged from the filter box 3, the inner wall of the filter box 3 is fixedly connected with an oblique plate 9, and a discharge port 10 is provided on the side of the oblique plate 9 close to the guide plate 6, the inside of the filter box 3 is fixedly connected with an elastic member 15, and the end of the elastic member 15 away from the filter box 3 is fixedly connected to the material leveling plate 16, the outer wall of the filter box 3 is fixedly connected with a motor 11, and the output end of the motor 11 is transmission-connected with a belt 14, the outer wall of the filter box 3 is sleeved with a rotating shaft 12, and the rotating shaft 12 is transmission-connected with the drive shaft of the motor 11 through the sleeved belt 14, and a cam 13 is fixedly connected to one side of the rotating shaft 12 located inside the filter box 3.

[0028] One end of the material leveling plate 16 away from the elastic member 15 is fixedly connected to the protrusion 17, the outer wall of the filter box 3 is rotatably connected to the rotating rod 18, the side wall of the rotating rod 18 is transmission-connected to the output end of the motor 11 through the sleeved belt 20, the outer wall of the rotating rod 18 is fixedly connected to the half gear 19, the outer wall of the filter box 3 is fixedly connected to the guide rail 22, the guide rail 22 is slidably connected to the movable frame 21, the inner wall of the movable frame 21 is fixedly connected to the teeth, the half gear 19 is meshed with the teeth, the rotation of the rotating rod 18 drives the half gear 19 to rotate, and further makes the movable frame 21 reciprocate laterally, and the side wall of the movable frame 21 is fixedly connected to the limit rod 23.

[0029] The feeding device 4 puts the resin particles into the filter box 3, and the resin particles roll to the other side through the inclined movable plate 5. Large impurities are discharged from the filter box 3 through the guide plate 6, and the resin particles can leak to the top of the filter plate 8 through the filter hole 7. The resin particles fall onto the leveling plate 16 along the filter plate 8, and the smaller impurities that pass through the filter plate 8 are discharged from the filter box 3 through the discharge port 10. The resin particles on the leveling plate 16 are decelerated and spread out, and then fall into the preheating box 2 through the through holes set on the leveling plate 16, so as to improve the uniformity of the material discharge. Specifically, the motor 11 starts to drive the rotating shaft 12 and the cam 13 to rotate through the transmission action of the belt 14, and the cam 13 lifts the movable plate 5, so that the movable plate 5 shakes longitudinally, thereby accelerating the separation speed of large impurities and resin particles.

[0030] In addition, the motor 11 drives the rotating rod 18 to rotate through the transmission action of the belt 20, and drives the half gear 19 to rotate, so that the movable frame 21 and the limit rod 23 can reciprocate laterally. The limit rod 23 reciprocates laterally to squeeze the protrusion 17, and then the material leveling plate 16 moves in the direction away from the limit rod 23. When the limit rod 23 cancels the squeezing of the protrusion 17, the elastic member 15 pushes the material leveling plate 16 to reset, so that the material leveling plate 16 can swing back and forth left and right, further dispersing the resin particles laid thereon, and then falling into the preheating box 2 through the through hole, thereby improving the degree of dispersion of the resin particles and avoiding accumulation in one place.

[0031] The mixing box 1 mixes the resin particles and the additives, and the preheating box 2 preheats and divides the particles (for example, an EVA particle processing and mixing device with publication number CN219926574U, the disclosed technical scheme records that the resin particles are heated by a preheating roller, the resin particles are divided by a dividing roller, and then the material is stirred by a stirring mechanism, which is the same as the working principle of the above-mentioned preheating, dividing and mixing, so it is not described in detail in this case).

[0032] The feeding device 4 puts the resin particles into the filter box 3, and the large impurities are discharged from the filter box 3 through the guide plate 6. The resin particles leak through the filter holes 7 to the top of the filter plate 8, and the smaller impurities are discharged from the filter box 3 through the discharge port 10. The resin particles fall onto the leveling plate 16 along the filter plate 8. The resin particles are decelerated and spread out, and fall into the preheating box 2 through the through holes set on the leveling plate 16. The motor 11 starts to drive the cam 13 to rotate, and the cam 13 lifts the movable plate 5 to make the movable plate 5 shake up and down. Further, the motor 11 drives the rotating rod 18 to rotate through the transmission action of the belt 20, so that the limit rod 23 reciprocates laterally, and the limit rod 23 reciprocates laterally to squeeze the protrusion 17, so that the leveling plate 16 moves in the direction away from the limit rod 23, so that the leveling plate 16 swings back and forth left and right, and further disperses the resin particles laid thereon.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
