[0030] Embodiment 2:

[0031] The utility model discloses a self-cleaning plastic shredder, wherein a discharging port is arranged at the lower front end of a shredding box 1; a main body of a crushing roller 2 is a cylindrical shaft body, and teeth are symmetrically arranged at equal distances from left to right on the outer side of the shaft body, and the teeth of two groups of crushing rollers 2 are staggered and contacted with each other; an arc-shaped scraper 62 and a cleaning brush 66 above a cleaning mechanism 6 are distributed according to the positions of the cylindrical shaft body and teeth that are in contact with each other, so as to avoid that the crushing roller 2 cannot be properly cleaned.

[0032] The utility model provides a self-cleaning plastic shredder through improvement, and its working principle is as follows;

[0033] First, when using this device, first place the device in the working area, and then connect the device to the external power supply and external controller to provide the required power for the operation of the device;

[0034] Second, firstly, the plastic to be shredded is put above the two groups of crushing rollers 2, and the first motor 4 is started through the external controller. The first motor 4 drives the two groups of crushing rollers 2 to rotate through the gear box 3, so that the plastic is driven to be shredded and falls into the lower end of the shredding box 1. Then, the second motor 52 is started through the controller, and the second motor 52 drives the threaded rod 53 to rotate through the output shaft.

[0036] The utility model provides a self-cleaning plastic shredder through improvement. By arranging a push-out mechanism 5 at the lower end of the shredding box 1, when the shredded plastic falls to the lower end of the shredding box 1, the second motor 52 can drive the push-out plate 54 to move forward through the threaded rod 53, so that the accumulated plastic is pushed out of the shredding box 1 at one time, and the pollution caused by the plastic falling randomly is avoided. By arranging a cleaning mechanism 6 at the middle end of the shredding box 1, after the crushing roller 2 shreds the plastic, when some plastic fragments stick to the cylindrical shaft or teeth of the crushing roller 2, the two places will contact with the upper end of the arc scraper 62 and the cleaning brush 66 respectively through the rotation of the crushing roller 2, so as to complete the cleaning operation of the crushing roller 2, and avoid the plastic sticking to the crushing roller 2 and causing work obstruction.
