Through the coordinated use of the annular groove 14 and the sliding ring 4, the mounting ring 5 can be easily rotated on the chassis 1.

[0026] As a technical optimization solution of the present invention, a horizontal plate 25 is installed on the side of the mounting plate 7 away from the strip plate 9. A circular opening is opened on the top of the horizontal plate 25, and a feeding hopper 26 is installed in the circular opening.

[0032] When the present invention is in use, when it is necessary to crush the waste plastic bags, first, the motor 2 is started, and the output shaft of the motor 2 drives the gear 3 to rotate, and the gear 3 can drive the gear ring 6 to rotate, and then the mounting ring 5 rotates, and the rotation of the mounting ring 5 can drive the crushing box 13 to rotate, and the empty crushing box 13 can be moved to the bottom of the feeding hopper 26. At this time, the waste plastic bags that need to be crushed are introduced into the feeding hopper 26, and the waste plastic bags that need to be crushed can fall into the crushing box 13 through the feeding hopper 26, and the feeding process of the waste plastic bags can be completed.

[0033] After the waste plastic bags to be crushed are loaded into the crushing box 13, the output shaft of the motor 2 is used again to drive the gear 3 to rotate so that the mounting ring 5 rotates until the crushing box 13 loaded with the waste plastic bags is moved to the position just below the grid cutter 19 and stops. At this time, the first electric telescopic rod 10 is started, and the piston rod of the first electric telescopic rod 10 can push the carrying plate 12 downward. The downward movement of the carrying plate 12 can drive the two fixing plates 18 to move downward. The downward movement of the two fixing plates 18 can drive the grid cutter 19 to move downward until the grid cutter 19 enters the crushing box 13 loaded with the waste plastic bags, and the grid cutter 19 is used to cut and crush the waste plastic bags in the crushing box 13. The waste plastic bag that needs to be crushed in the crushing box 13 can be cut and crushed into several plastic pieces of equal size at one time, and the grid cutter 19 is used to cut and crush the waste plastic bag, so that the cut and crushed plastic pieces are of equal size, avoiding the problem that the traditional waste plastic bag crushing device cuts and crushes the waste plastic bag into plastic pieces of different sizes. By using the present device to cut and crush the waste plastic bag, the waste plastic bag can be cut and crushed into pieces of equal size at one time, eliminating the need to cut and crush large plastic pieces in the later stage, and eliminating the need to screen small plastic pieces in the later stage, thereby improving the cutting and crushing efficiency of the waste plastic bag.

[0034] After the waste plastic bags in the crushing box 13 are cut and crushed, the output shaft of the motor 2 is used to drive the gear 3 to rotate again, so that the gear ring 6 drives the mounting ring 5 to rotate, and then the crushing box 13 loaded with the crushed plastic pieces moves along with the mounting ring 5 until the crushing box 13 loaded with the cut and crushed plastic pieces moves to the side of the collection box 15 and stops. The electric gate 20 is opened, and the second electric telescopic rod 24 is started. The piston rod of the second electric telescopic rod 24 pushes the pushing plate 21 to push the cut and crushed plastic pieces in the crushing box 13, and then pushes the cut and crushed plastic pieces through the opening into the collection box 15, which can complete the automatic unloading processing of the cut and crushed plastic pieces. By using several crushing boxes 13 to load, cut, crush and unload materials uninterruptedly, it can continuously load, cut, crush and unload waste plastic bags, ensuring the continuity of cutting and crushing of waste plastic bags and ensuring the efficiency of cutting and crushing of waste plastic bags.
