The driving of the driving motor 24 drives the transmission shaft 25 and the first sprocket 26 to rotate. The rotation of the first sprocket 26 drives the second sprocket 30 and the transmission rod 27 to rotate. The rotation of the transmission rod 27 drives the multiple crushing blades 28 to rotate to crush the plastic parts after extrusion. The completely crushed plastic falls to the bottom of the partition rod 46, and the incompletely crushed plastic is isolated on the partition rod 46. The operation of the connecting motor 33 causes the first rotating rod 34 and the second rotating rod 35 to rotate. The rotation of the first rotating rod 34 causes the reciprocating lead screw 47 to rotate.

The movement of the moving block 49 drives the vertical column 51 and the cleaning brush to move left and right, so that the incompletely crushed plastic is brushed into the two receiving boxes 31. Since the rotation of the first rotating rod 34 and the second rotating rod 35 will drive the driving wheel and the conveyor belt 38 to rotate, the rotation of the conveyor belt 38 brings the incompletely crushed plastic parts into the multiple spiral conveyor rods 40. The rotation of the transmission shaft 25 drives the third sprocket 41 and the fourth sprocket 42 to rotate, thereby driving the multiple spiral conveyor rods 40 to rotate, and sending the collected incompletely crushed plastic parts into the crushing box 23 again for secondary crushing. Repeating this process makes the crushing of the shredded parts more thorough.

[0020] The usage process of the present invention is as follows: The user starts the hydraulic press 5 to work, so that the extrusion mechanism performs extrusion and crushing work on the plastic part. At the same time, the transmission motor 24 and the connection motor 33 are started to work, so that the shredding mechanism works to shred the plastic part after extrusion. The user puts the plastic part into the extrusion box 9 and starts the hydraulic press 5 to work, so that the lifting plate 6 and the extrusion plate 8 move downward. The extrusion plate 8 moves downward to extrude and crush the plastic part, making the plastic part into fragments. When the extrusion plate 8 moves to the maximum position, the first magnet 19 attracts the second magnet 20. After the extrusion is completed, the extrusion plate 8 moves upward, so that the first magnet 19 and the second magnet 20 move upward. The upward movement of the second magnet 20 drives the pull rope 12 to stretch outward, thereby driving the two baffles 10 to move outward, so that the plastic part after extrusion falls into the shredding box 23. The user starts the transmission motor 24 and the connection motor 33 to work. The transmission motor 24 works to drive the transmission shaft 25 and the first sprocket 26 to rotate. The rotation of the first sprocket 26 drives the second sprocket 30 and the transmission rod 27 to rotate. The rotation of the transmission rod 27 drives a plurality of shredding blades 28 to rotate to shred the plastic part after extrusion. The completely shredded plastic falls to the bottom of the partition rod 46, and the incompletely shredded plastic is isolated on the partition rod 46. The connection motor 33 works to make the first rotating rod 34 and the second rotating rod 35 rotate. The rotation of the first rotating rod 34 makes the reciprocating screw rod 47 rotate. The rotation of the reciprocating screw rod 47 drives the sliding block 48 and the moving block 49 to move. The movement of the moving block 49 drives the column 51 and the cleaning brush to move left and right, so that the incompletely shredded plastic is brushed into the two receiving boxes 31. Since the rotation of the first rotating rod 34 and the second rotating rod 35 will drive the transmission wheel and the conveyor belt 38 to rotate, the conveyor belt 38 rotates to bring the incompletely shredded plastic parts into the plurality of spiral conveyor rods 40. The rotation of the transmission shaft 25 drives the third sprocket 41 and the fourth sprocket 42 to rotate, thereby driving the plurality of spiral conveyor rods 40 to rotate, and sending the collected incompletely shredded plastic parts into the shredding box 23 again for secondary shredding. Repeating this process makes the shredded parts more thoroughly shredded.
