[0032] Working principle: the polyethylene wax powder particles are transported into the grinding bin 43 through the feeding port 430, and then the control center 30 is used to start the first rotary drive assembly 400, the first airflow device 432, the second airflow device 442 and the third airflow device 451. The first rotary drive assembly 400 is started to drive the first meshing wheel 401 to rotate, the first meshing wheel 401 drives the second meshing wheel 410 to rotate, the second meshing wheel 410 drives the first output shaft to rotate through the first linear drive assembly 42, the first output shaft drives the movable disc 44 to rotate, the movable disc 44 drives the adjusting table 441, the fixed plate 444, the rotary scraper 445 and the crushing plate 446 to rotate through the second linear drive assembly 440 and the second output shaft, when the polyethylene wax particles enter the grinding bin 43, the first airflow device 432 sprays the airflow between the crushing plate 446 and the plurality of crushing teeth 431, the polyethylene wax particles are preferentially passed through the crushing plate 446 and the plurality of crushing teeth 431 under the action of the airflow, the crushing plate 446 rotates at the plurality of crushing teeth 431, on the one hand, the teeth and the crushing teeth 431 are engaged to crush the polyethylene wax powder, on the other hand, the centrifugal force generated by the rotation of the crushing plate 446 drives the polyethylene wax particles to move continuously at the crushing teeth 431 until the particles are crushed and become smaller, at this time, the diameter of the polyethylene wax particles is larger than the distance between the crushing plate 446 and the plurality of crushing teeth 431, so that they have a tendency to fall when passing through the area not affected by the airflow sprayed by the first airflow device 432.

[0033] The guide plates 453 are initially inclined, and the second airflow device 442 and the third airflow device 451 spray airflows at this time so that the polyethylene wax particles collide and rub with each other to achieve secondary crushing and grinding, at the same time, the airflow sprayed by the second airflow device 442 prevents the polyethylene wax particles from falling to the movable disc 44, and the airflow sprayed by the third airflow device 451 has a tendency to generate a rotational airflow under the action of the four guide plates 453, which improves the crushing quality of the polyethylene wax particles, and the airflow sprayed by the third airflow device 451 blows the secondary crushed and ground polyethylene wax powder to the first conveying pipe 5, thereby the device crushes and grinds the polyethylene wax particles in a double way of mechanical crushing and airflow crushing, improves the crushing and grinding quality of the device, and is convenient for users to use; The rotation of the spiral scraper 445 in the above steps guides the airflow sprayed by the second airflow device 442 and the third airflow device 451, and the spiral airflow is generated due to the curved arc-shaped guide of the spiral scraper 445. The positions of the guide plates 453 and the spiral scraper 445 are staggered, which further complicates the spiral airflow guided by the guide plates 453, and makes the movement path of the polyethylene wax particles more complex when moving from the grinding bin 43 to the first conveying pipe 5, thereby increasing the movement distance of the polyethylene wax particles in the grinding bin 43, improving the probability of mutual collision between the polyethylene wax particles, making the crushing more sufficient, reducing the proportion of coarse particles in the polyethylene wax powder, and improving the crushing and grinding quality of the device, facilitating the use of the user. When the polyethylene wax powder is adhered to the inner wall of the grinding bin 43, the first rotary driving assembly 400 is closed, the electric rotating shaft 452 and the second linear driving assembly 440 are opened by the control center 30, the electric rotating shaft 452 is opened to drive the inclined guide plate 453 to rotate until it is vertically upward, the second output rod is pushed out and moved by the second linear driving assembly 440, the second output rod moves to drive the crushing plate 446 to move until the teeth on the surface of the crushing plate 446 are engaged with the crushing teeth 431, at this time the first linear driving assembly 42 is opened by the control center 30, the first output rod drives the movable disc 44 to move upward as a whole, the movable disc 44 moves to make the teeth on the surface of the crushing plate 446 move at the crushing teeth 431, and in the process of moving, the polyethylene wax powder that may be stuck at the crushing teeth 431 is crushed, avoiding affecting the subsequent crushing and grinding.

[0034] Until the crushing plate 446 moves to the top of the plurality of crushing teeth 431, the "L"-shaped structure of the four guide plates 453 is attached to the outer surface of the connection between the first conveying pipe 5 and the grinding bin 43, and the scraper 454 is attached to the inner wall of the connection between the first conveying pipe 5 and the grinding bin 43, at this time the second linear driving assembly 440 is opened by the control center 30 to reset the second output rod and the crushing plate 446, and the second rotary driving assembly 443 is opened, the second rotary driving assembly 443 is opened to drive the fixed plate 444 to rotate until the spiral scraper 445 is attached to the inner wall of the grinding bin 43, at this time the first rotary driving assembly 400 is opened again, the rotation of the movable disc 44 drives the spiral scraper 445 to rotate on the inner wall of the grinding bin 43, the "L"-shaped structure of the guide plate 453 rotates on the outer surface of the connection between the first conveying pipe 5 and the grinding bin 43, and the scraper 454 rotates on the inner wall of the connection between the first conveying pipe 5 and the grinding bin 43, thereby performing the scraping treatment of the polyethylene wax powder, and the airflow sprayed by the first airflow device 432, the second airflow device 442 and the third airflow device 451 can convey the scraped polyethylene wax powder to the first conveying pipe 5 as described above, thereby the device can perform comprehensive scraping treatment on the adhered polyethylene wax powder, improve the cleaning quality of the device, and facilitate the use of the user. The polyethylene wax powder is then transported through the first conveying pipe 5 to the screening device 6, and the cyclone collector and dust collection bag inside the screening device 6 screen the large polyethylene wax particles and then transport the screened particles through the second conveying pipe 7 to the collecting device 8, and the collected particles are collected by the collecting cylinder inside the collecting device 8.
