[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6 As shown, a recycled EVA plastic particle screening machine includes a box body 1, a collecting box 101 is slidably connected to the box body 1, a replacement mechanism for facilitating the change of screening specifications is installed in the box body 1, a sieve plate 3 is installed in the replacement mechanism, two sets of locking mechanisms for limiting are provided on the front side of the replacement mechanism, and a stirring mechanism for preventing blockage is provided above the replacement mechanism.

[0027] The stirring mechanism includes a mounting plate 501, which is welded to the top of the box body 1. The top of the mounting plate 501 is connected to the motor 502 by bolts, and the bottom of the mounting plate 501 is welded with a mounting frame 503. A rotating shaft 504 is rotatably connected between the mounting frame 503 and the mounting plate 501 through a bearing. The output shaft of the motor 502 is connected to the top of the rotating shaft 504 by a coupling. A rotating plate 505 is welded to the bottom of the rotating shaft 504. The rotating plate 505 is a cross-shaped plate made of stainless steel. A plurality of stirring rods 506 are welded to the bottom of the rotating plate 505. The movement of the motor 502 drives the rotating shaft 504 to rotate, thereby driving the rotating plate 505 to rotate, and then utilizing the plurality of stirring rods 506 to stir the plastic particles to avoid blockage.

[0028] The locking mechanism includes two fixing nuts 401, which are welded to the front side of the box body 1. A locking bolt 403 is threadedly connected to the fixing nut 401. A locking plate 402 is arranged between the fixing nut 401 and the locking bolt 403. The locking plate 402 is a T-shaped plate made of aluminum alloy. The front side of the locking plate 402 is attached to the rear side of the first mounting block 201. When the screen plate 3 needs to be replaced, the locking bolt 403 is unscrewed and the locking plate 402 is removed so that the locking plate 402 no longer hinders the sliding of the first mounting block 201. When locking is achieved, the locking plate 402 is placed on the front side of the fixing nut 401 and the locking bolt 403 is tightened to achieve locking of the replacement mechanism.

[0029] The replacement mechanism includes a first mounting block 201, which is slidably connected to the inner wall of the box body 1.

The first mounting block 201 is taken out by hand. At this time, since the first mounting block 201 and the second mounting block 203 are connected by the connecting rod 205, the first mounting block 201 will drive the second mounting block 203 to slide, thereby taking out the replacement mechanism as a whole. Then, the connecting rod 205 is rotated to unscrew the connecting rod 205 from the second mounting hole 204, and then the connecting rod 205 is pulled to pull the connecting rod 205 out of the first mounting hole 202, thereby releasing the connection between the first mounting block 201 and the second mounting block 203, thereby removing the sieve plate 3 and replacing it with a sieve plate 3 of another specification. Then, the first mounting block 201 and the second mounting block 203 are locked using the connecting rod 205, and then the first mounting block 201 and the second mounting block 203 are inserted into the box body 1.

[0030] Working principle: When in use, the plastic particles to be screened are poured into the box body 1 from the top, and the motor 502 is moved to drive the rotating shaft 504 to rotate, thereby driving the rotating plate 505 to rotate, and then using multiple stirring rods 506 to stir the plastic particles to avoid blockage. Then, the plastic particles that meet the size will pass through the screen plate 3 and fall into the collection box 101. When the screen plate 3 needs to be replaced, the locking bolt 403 is unscrewed, and then the locking plate 402 is removed so that the locking plate 402 no longer hinders the sliding of the first mounting block 201. Then, the first mounting block 201 is taken out using the handle. At this time, since the first mounting block 201 and the second mounting block 203 are connected by the connecting rod 205, the first mounting block 201 is Block 201 will drive the second mounting block 203 to slide, thereby taking out the replacement mechanism as a whole, then rotate the connecting rod 205, unscrew the connecting rod 205 from the second mounting hole 204, and then pull the connecting rod 205 to pull the connecting rod 205 out of the first mounting hole 202, thereby releasing the connection between the first mounting block 201 and the second mounting block 203, thereby removing the sieve plate 3 and replacing it with a sieve plate 3 of another specification, and then lock the first mounting block 201 and the second mounting block 203 with the connecting rod 205, and then insert the first mounting block 201 and the second mounting block 203 into the box body 1, and then place the locking plate 402 on the front side of the fixing nut 401, tighten the locking bolt 403, and lock the replacement mechanism.
