[0038] The screen 402 is axially slidably mounted on the outer wall of the connecting seat 401, and the screen 402 is used to screen the materials inside the collecting box 2;

[0039] The limit block 408 is vertically slidably mounted on the inner wall of the top of the connecting base 401 and extends to the outside of the top of the connecting base 401. The limit block 408 is used to provide a limit for the connection between the connecting base 401 and the collection box 2;

[0040] The second positioning rod 409 is fixed to the inner wall of the connecting seat 401 and passes through the limiting block 408. The second positioning rod 409 is used to provide a guide for the movement of the limiting block 408.

[0041] The two ends of the second spring 410 are respectively clamped to the bottom end of the limit block 408 and the inner wall of the connecting seat 401. The second spring 410 is used to provide a restoring elastic force for the limit block 408 after movement.

[0042] The transmission unit includes a force block 403, a rotating rod 404, a stop block 405, a first positioning rod 406, and a first spring 407;

[0043] The force block 403 is fixed on the top of the screen 402, and is used to receive the thrust from the resisting block 405;

[0044] The rotating rod 404 is connected to the output end of the suction fan 3, and the rotating rod 404 is used to synchronously drive the stop block 405 to rotate;

[0048] In this embodiment, through this structure, after the resin is crushed by the crushing box 1, the dust scattered during the crushing process is collected by the suction fan 3 inside the collection box 2. The collected dust will enter the collection box 2 and fall on the screen 402. The working suction fan 3 will synchronously drive the rotating rod 404 connected to the output end of the suction fan 3 to rotate. The rotating rotating rod 404 synchronously drives the outer wall fixed block 405 to rotate, so that the arc surface of the end of the block 405 contacts the outer wall of the force block 403 to give the force block 403 a 03 thrust, the stressed force block 403 synchronously drives the screen 402 to move along the inside of the connecting seat 401, and the screen 402 moves along the outer wall of the first positioning rod 406 and gives the first spring 407 an extrusion force.

[0050] In this embodiment: through this structure, when the screen 402 needs to be replaced and cleaned, the limit block 408 can be pressed downward by applying pressure to the limit block 408. The limit block 408 under force will move vertically along the internal movable groove of the connecting seat 401. The movable limit block 408 will move along the outer wall of the second positioning rod 409 and apply squeezing force to the second spring 410 until one end of the limit block 408 is disengaged from the limit groove of the collection box 2. At this time, the connecting seat 401 can be pulled out, and the screen 402 can be taken out synchronously to clean the screen 402.
