[0133] It comprises a revolving door 38, which is arranged at the front of the box body 2, one side of the revolving door 38 is hinged to the box body 2, and the axis of the hinge is vertical.

[0134] This enables the staff to remove the larger plastic particles on the screen 23.

[0135] Working principle: When using this equipment, the staff pours the plastic into the feed hopper 4, and then the plastic falls along the discharge plate 8 to the upper surface of the two crushing rollers 3. The staff starts the two crushing rollers 3 through the controller 35, and the two crushing rollers 3 crush the plastic. The crushed plastic particles fall along the guide plate 36 into the screening frame 22, and after being screened by the screen 23, they are discharged from the discharge port 5.

[0136] When crushing plastic, the staff starts the first reversing motor 6 and the second reversing motor 7 through the controller 35. The rotating shafts of the first reversing motor 6 and the second reversing motor 7 respectively drive the two unloading plates 8 to swing up and down. The swing of the unloading plates 8 allows the plastic accumulated above the unloading plates 8 to fall smoothly onto the two crushing rollers 3.

[0137] When the rotating shaft of the first reversing motor 6 drives the blanking plate 8 to move downward, the blanking plate 8 drives the slider 11 to move downward along the round rod 10, the slider 11 drives the plug rod 13 to move downward, the plug rod 13 drives the first piston 14 to move downward, the first piston 14 pushes the air in the first cylinder body 12 into the second cylinder body 15 through the connecting pipe 17, and then the air squeezes the second piston 16, the second piston 16 moves right, the second piston 16 drives the sliding rod 18 to move right, the sliding rod 18 drives the rack 34 to move right, drives the limit plate 19 to move right, drives the cylinder 21 to move right, the telescopic end of the cylinder 21 drives the screening frame 22 to move right, and the screening frame 22 drives the screen 23 to move right.

[0138] When the sliding rod 18 drives the limiting plate 19 to move rightward, the limiting plate 19 squeezes the spring 20, and the spring 20 contracts.

[0139] When the sliding rod 18 drives the rack 34 to move right, the rack 34 drives the first gear 33 to rotate forward, the first gear 33 drives the one-way overrunning clutch 32 to rotate forward, the one-way overrunning clutch 32 drives the second rotating shaft 30 to rotate forward, the second rotating shaft 30 drives the second bevel gear 31 to rotate forward, the second bevel gear 31 drives the first bevel gear 29 to rotate forward, the first bevel gear 29 drives the first rotating shaft 27 to rotate forward, the first rotating shaft 27 drives the fan 28 to rotate forward, the fan 28 rotates, so that the dust generated when screening the plastic particles is discharged through the air port and the wind tube 26, and then filtered to prevent the dust from floating and affecting the surrounding environment.

[0140] When the rotating shaft of the first reversing motor 6 drives the blanking plate 8 to move upward, the blanking plate 8 drives the slider 11 to move upward along the round rod 10, the slider 11 drives the plug rod 13 to move upward, and the plug rod 13 drives the first piston 14 to move upward, so that the air in the second cylinder body 15 enters the first cylinder body 12 through the connecting pipe 17, thereby causing the second piston 16 to move left, and the spring 20 is reset, the spring 20 drives the limit plate 19 to move left, the limit plate 19 and the second piston 16 drive the sliding rod 18 to move left, the sliding rod 18 drives the rack 34 to move left, drives the cylinder 21 to move left, the telescopic end of the cylinder 21 drives the screening frame 22 to move left, the screening frame 22 drives the screen 23 to move left, the screen 23 moves back and forth left and right in a shaking state, thereby improving the efficiency of screening plastic particles.

[0141] When the sliding rod 18 drives the rack 34 to move left, the rack 34 drives the first gear 33 to rotate in the opposite direction. Due to the one-way overrunning clutch 32, the first gear 33 cannot drive the one-way overrunning clutch 32 to rotate in the opposite direction, and then the second rotating shaft 30 will not rotate in the opposite direction, thereby preventing the fan 28 from rotating in the opposite direction.

[0142] When the screen 23 moves back and forth left and right, the staff controls the cylinder 21 to move up and down through the controller 35, the cylinder 21 drives the screening frame 22 to move up and down, and the screening frame 22 drives the screen 23 to move up and down to prevent the plastic particles from clogging the mesh of the screen 23.

[0143] After a period of time, the plastic is crushed, and the staff turns off the crushing roller 3, the first reversing motor 6, the second reversing motor 7, and the cylinder 21 through the controller 35, and then opens the revolving door 38 to take out the large-sized plastic particles on the screen 23.

[0144] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
