The sieve plate 6 is slidably connected to the inner side of the screening shell 2. The sieve plate 6 is in an inclined state on the inner side of the screening shell 2, and one end of the sieve plate 6 is inclined toward the bottom of the inner side of the first discharge port 4.

[0030] The shaking mechanism includes a driving assembly and a force transmission assembly. A fixed cavity plate 7 is fixed to the side of the screening shell 2 away from the guide hopper 5.

[0031] The driving assembly includes a servo motor 8, a rotating wheel disc 9, a force-applying rod 10, a carrying rod 11 and a force-transmitting cylinder 12. The servo motor 8 is fixed to the side of the fixed cavity plate 7 away from the screening shell 2. The output end of the servo motor 8 passes through the fixed cavity plate 7 and is fixed with a rotating wheel disc 9. One side of the rotating wheel disc 9 and a position deviating from the center of the circle is rotatably connected to the force-applying rod 10 through a pin. One end of the force-applying rod 10 is rotatably connected to the carrying rod 11 through a pin. The outer side of the carrying rod 11 is slidably connected to a rectangular plate, which is fixed to the screening shell 2. A force-transmitting cylinder 12 is fixed to the top of the carrying rod 11. When the servo motor 8 is started, the output end of the servo motor 8 drives the rotating wheel disc 9 to rotate, and under the limit of the rectangular plate, the carrying rod 11 can be moved vertically.

[0034] Example 2

[0035] Embodiment 1 is further optimized, specifically, as Figure 5 As shown, a conveying mechanism is assembled on the top of the fixed base 1, and the conveying mechanism includes a fixed mounting frame 19, a conveying roller 20, a force motor 21 and a conveyor belt 22. A fixed mounting frame 19 is fixed on the top of the fixed base 1 and at a position corresponding to the bottom of the guide hopper 5. Two conveying rollers 20 are rotatably connected to the two sides of the inner top of the fixed mounting frame 19 through bearings, and the outer sides of the two conveying rollers 20 are connected through a conveyor belt 22. A force motor 21 is fixed to the end of one side of the fixed mounting frame 19, and the output end of the force motor 21 passes through the inner side of the fixed mounting frame 19 and is fixed to one of the conveying rollers 20. The force motor 21 is started, and when the polymer material particles that do not meet the specifications are discharged along the outer side of the screen plate 6 through the first discharge port 4 into the guide hopper 5, the polymer material particles fall on the conveyor belt 22 for transportation, which is convenient for the next step of processing and recycling or for other uses.

[0036] From the above, we can know that:

[0037] The utility model aims at the technical problem that in the prior art, when screening antistatic polymer materials, the top of the sieve is prone to accumulation, which causes the mesh of the sieve to be easily blocked, and there is room for improvement; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0038] The device is moved to a designated area, and then electrically connected to an external power source, and then polymer particles are added to the feed port 3, and then started, and the polymer particles that meet the specifications are screened by the sieve plate 6 so that the polymer particles fall naturally and are discharged through the first discharge port; at the same time, the polymer particles that do not meet the specifications fall along the outer side of the sieve plate 6 through the first discharge port 4 into the guide hopper 5 and are discharged from the guide hopper 5;

[0039] When the sieve plate 6 is in a state of being blocked by the accumulation of the polymer material particles, the servo motor 8 is started, and the output end of the servo motor 8 drives the rotating wheel disc 9 to rotate. Because the rotating wheel disc 9 is rotationally connected with the force applying rod 10, the force applying rod 10 is rotationally connected with the carrying rod 11, the carrying rod 11 is slidingly connected with the rectangular plate, and the carrying rod 11 is fixed with the force transmitting cylinder 12, the carrying rod 11 can push the connecting cylinder 17 upward through the force transmitting cylinder 12 to move, and then the connecting cylinder 17 moves along the inner side of the bracket 16, pushing the shifting support plate 14 upward, so that the sieve plate 6 can be shaken upward, and at the same time, the rotating wheel disc 9 continues to rotate, so that the shifting support plate 14 starts to push downward, so that the sieve plate 6 can be shaken downward, and this reciprocating process can accelerate the screening of the polymer material particles on the sieve plate 6, avoid the accumulation and blockage of the polymer material particles on the sieve plate 6, and prevent the screening efficiency from being affected.

[0040] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0041] 1. The utility model uses the structural design of the screening mechanism and the shaking mechanism to make the device easy to screen the polymer particles. At the same time, it can push the sieve plate 6 to shake to prevent the polymer particles on the sieve plate 6 from piling up, thereby speeding up the work efficiency and improving the efficiency of the device.

[0042] 2. The utility model uses the structural design of the conveying mechanism to enable the device to convey polymer particles that do not meet the screening specifications, so as to facilitate the next step of processing and recycling or to keep them for other uses.
