[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The cross-section of the receiving tank of this utility model is arc-shaped, and the EPDM rubber particles will fall into it naturally. The pusher plate drives the elastic plate to move inside the receiving tank, so that the EPDM rubber particles that are stuck together are subjected to friction and roll. The force applied by the elastic plate to the EPDM rubber particles will exceed the adhesion force between the objects, thereby causing them to separate. This avoids the first screen hole being blocked by the EPDM rubber particles that are stuck together, ensuring the normal operation of the screening work and improving the screening efficiency.

This utility model allows for the replacement of screening plates according to different specifications of EPDM rubber granules, enabling individual EPDM rubber granules to pass through the second screen hole and reach the bottom of the box. At the same time, rotating the bolt can push the elastic plate further into the receiving tank. Through the action of the elastic element, the elastic plate can immediately return to its original position after the bolt moves away from the elastic plate, so that the elastic plate can maintain contact with EPDM rubber granules of different sizes for screening.

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example

[0020] like Figure 1 and Figure 2As shown, the rubber granule screening device includes a housing 10 and a pusher plate 20. An interceptor plate 11 is fixedly installed inside the housing 10. The interceptor plate 11 has several receiving slots 12, and the receiving slots 12 have several first screen holes 13. The pusher plate 20 is provided with an elastic plate 28 on the side close to the interceptor plate 11, which is the same number as the receiving slots 12. The elastic plate 28 corresponds one-to-one with the receiving slots 12. The material of the elastic plate 28 is polyurethane plastic, but is not limited to polyurethane plastic, so that the elastic plate 28 has excellent elasticity and is easy to bend.

[0021] Specifically, the top of the box 10 is designed with an opening. EPDM rubber granules are placed on the interceptor plate 11 from the top of the box 10. Due to the arc-shaped cross-section of the receiving groove 12, the EPDM rubber granules will naturally fall into it. Then, the pusher plate 20 drives the elastic plate 28 to move inside the receiving groove 12, causing the EPDM rubber granules that are stuck together to roll due to friction. The force applied to the EPDM rubber granules by the elastic plate 28 will exceed the adhesion force between the objects, thereby causing separation. This avoids the first screen hole 13 being blocked by the EPDM rubber granules that are stuck together, ensuring the normal operation of the screening work and improving the screening efficiency.

[0022] like Figure 1 As shown, a detachable screening plate 14 is provided on the side of the interceptor plate 11 away from the push plate 20. The screening plate 14 has a number of second screening holes 15 that are the same as the number of first screening holes 13. The second screening holes 15 correspond one-to-one with the first screening holes 13.

[0023] Specifically, the sieve plate 14 is replaced according to the different specifications of EPDM rubber granules, so that individual EPDM rubber granules can pass through the second sieve hole 15 to the bottom of the box 10.

[0024] like Figure 1 As shown, a connecting block 21 is fixedly connected to the side of the push plate 20 away from the interceptor plate 11. One connecting block 21 is movably fitted with a guide slide rod 22, which is fixedly connected to the housing 10. Another connecting block 21 is threadedly connected to a bidirectional screw rod 23, one end of which passes through the housing 10. A motor is fixedly installed on the outer wall of the housing 10, and the output end of the motor is fixedly connected to the bidirectional screw rod 23.

[0025] Specifically, the motor drives the bidirectional lead screw 23 to rotate. The bidirectional lead screw 23 is threadedly engaged with a connecting block 21, and the other connecting block 21 is slidably engaged with the guide slide rod 22, which can drive the push plate 20 to reciprocate axially.

[0026] like Figure 2 As shown, both sides of the elastic plate 28 are fixedly connected to the connecting plate 26. The connecting plate 26 has a sliding opening, and a one-way screw 25 fixedly connected to the push plate 20 is provided inside the sliding opening. The one-way screw 25 is threaded with a nut.

[0027] Specifically, the one-way lead screw 25 and the nut are threaded together so that after the nut is separated from the one-way lead screw 25, the connecting plate 26 and the elastic plate 28 can be removed.

[0028] like Figure 1 and Figure 2 As shown, an elastic element 27 is fixedly connected to one side of the slide. The elastic element 27 is, but is not limited to, using a spring. The elastic element 27 is fixedly connected to the one-way lead screw 25. The push plate 20 is threadedly connected to a bolt 24. One end of the bolt 24 abuts against the elastic plate 28.

[0029] Specifically, rotating the bolt 24 can push the elastic plate 28 further closer to the interior of the receiving groove 12. The force of the elastic element 27 can make the elastic plate 28 return to its original position immediately after the bolt 24 moves away from the elastic plate 28, so that the elastic plate 28 can keep in contact with EPDM rubber particles of different sizes for screening.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
