The filter unit includes a filter hole 31 opened on the top of the conveyor belt 3.

[0027] Furthermore, the PE plastic particles are transported by the conveyor belt 3 , and during the transport process, the filter holes 31 are used to filter the impurities and dust mixed in the PE plastic particles.

[0028] Example 2

[0029] like Figures 1-5 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, a support bracket 41 is fixedly installed on the top of the support bracket 4, a motor 42 is fixedly installed inside the support bracket 41, a driving rod 43 is fixedly installed on the output end of the motor 42, and a cam 44 is fixedly sleeved on the other end of the driving rod 43, and limiting blocks 45 are fixedly installed on the edge positions of both sides of the top of the support bracket 4, and connecting brackets 46 are provided on both sides of the support bracket 4, and a limiting slide plate 47 is fixedly installed on the inner top of the connecting bracket 46, and the limiting slide plate 47 is movable The push rod 48 is movably sleeved on the outer surface of the limit block 45, and a push rod 48 is fixedly installed on the inner bottom end of the connecting bracket 46. The other end of the push rod 48 passes through the load-bearing vertical plate 2 and extends on the inner side of the load-bearing vertical plate 2 and is located above the conveyor belt 3. The other end of the push rod 48 is fixedly connected to a toggle plate 49. The outer surface of the push rod 48 is located on the outer side of the load-bearing vertical plate 2 and is movably sleeved with a return spring 410. One end of the return spring 410 is fixedly installed on the outer surface of the load-bearing vertical plate 2, and the other end of the return spring 410 is fixedly installed on the inner bottom end of the connecting bracket 46.

[0030] Further, the output end of the motor 42 drives the drive rod 43 to cause the cam 44 to rotate at a constant speed. Every time the cam 44 rotates one circle, it will squeeze the limit sliding plates 47 on both sides, causing them to move outward. When the limit sliding plates 47 move outward, they will further push the connecting bracket 46 to move outward accordingly. The connecting bracket 46 pulls the push rod 48 to drive the dial plate 49 to move on the top of the conveyor belt 3. At this time, the return spring 410 is in a stretched state, which can promote the fluidity of the PE plastic particles on the conveyor belt 3.

A filter box 25 is fixedly installed at the middle position of the dust collection pipe 24.

[0033] Further, during the conveying and filtering process, the suction force is generated by starting the dust collection pump 23. Together with the dust collection pipe 24 and the dust collection hood 21, it is convenient to suck the impurity dust generated by filtering into the interior of the dust collection box 22 for unified collection and treatment.

[0034] Next, the working principle of the material conveying device for PE plastic particle production will be specifically described.

[0035] As Figures 1-5 shown, during use, the PE plastic particles are conveyed by the conveyor belt 3. During the conveying process, the impurity dust mixed in the PE plastic particles is filtered through the filter holes 31. Then, the output end of the motor 42 drives the drive rod 43 to cause the cam 44 to rotate at a constant speed. Every time the cam 44 rotates one circle, it will squeeze the limit sliding plates 47 on both sides, causing them to move outward. When the limit sliding plates 47 move outward, they will further push the connecting bracket 46 to move outward accordingly. The connecting bracket 46 pulls the push rod 48 to drive the dial plate 49 to move on the top of the conveyor belt 3. At this time, the return spring 410 is in a stretched state, which can promote the fluidity of the PE plastic particles on the conveyor belt 3. When the cam 44 moves away, the extrusion force will be lost, and it will rebound and reset under the elastic potential energy of the return spring 410, moving back and forth left and right in this way, further improving the filtration efficiency. During the conveying and filtering process, the suction force is generated by starting the dust collection pump 23. Together with the dust collection pipe 24 and the dust collection hood 21, it is convenient to suck the impurity dust generated by filtering into the interior of the dust collection box 22 for unified collection and treatment.
