[0016] The present invention can move the rotating shaft to the middle position of the crushing barrel when crushing plastic with lower strength, and then drive the blade to extend. When the rotating shaft drives the blade to rotate, the speed of the blade end is accelerated. At this time, the motor output can be reduced, the rotation speed of the rotating shaft is slowed down, and the speed of the blade end can be at a normal speed for crushing plastic, thereby reducing energy consumption. When the device drives the blade to extend and retract on the rotating shaft, the force arm of the blade can be changed, so that it can be flexibly used for crushing plastics with higher and lower strengths, and can effectively avoid damage to the blade, which is more convenient to use.

[0029] During operation, the waste plastics to be recycled are put into the crushing barrel 2, and then the first rotating mechanism is started, which drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, the multiple blades 6 arranged on the surface of the rotating shaft 5 can crush the waste plastics into particles, thereby completing the recycling of the waste plastics; when the plastics to be recycled are hard plastics, due to the greater strength of hard plastics, the blades 6 are easily broken during crushing. At this time, the sliding frame 4 is driven to move downward by the lifting mechanism, and the sliding frame 4 moves downward when it moves downward. When the rotating shaft 5 moves downward, the adjusting mechanism will drive the contraction mechanism to operate, and the contraction mechanism will drive all the blades 6 on the rotating shaft 5 to contract into the rotating shaft 5 at the same time; when the sliding frame 4 drives When the rotating shaft 5 moves to the lowest position, the rotating shaft 5 is close to the bottom end of the crushing barrel 2. Under the action of the retracting mechanism, the distance between the blade 6 and the bottom end of the crushing barrel 2 remains unchanged; when it is necessary to crush hard plastic, the force arm of the blade 6 is reduced, and the overall compressive resistance of the blade 6 during crushing is increased, thereby effectively preventing the blade 6 from being broken; when the device crushes plastic with lower strength, the rotating shaft 5 can be moved to the middle position of the crushing barrel 2, and then the blade 6 is driven to extend.

By maintaining a low-temperature environment inside the crushing barrel 2, the crushing effect of the blade 6 on waste plastics can be effectively improved.
