[0030] Working principle:

[0031] Adjustment process of the first crushing roller:

[0032] Connect the external power supply of the first motor 202 and start it. The first motor 202 drives the sprocket 203 to rotate, the sprocket 203 drives the chain 204 to rotate, the chain 204 drives the second block 205 to move, and the second block 205 drives the third block 206 to move to the right (as Figure 4), when the second block 205 reaches the bending part of the chain 204, the second block 205 slides within the third block 206, causing the second block 205 to drive the third block 206 to move in the reverse direction. The third block 206 drives the third plate 207 to move, and the third plate 207 drives the first crushing roller 5 to move, thereby changing the position between the first crushing roller 5 and the second crushing roller 6, and thus changing the size of the crushed PBT material. After the first crushing roller 5 moves to a suitable position, the first motor 202 is turned off. In the above-mentioned manner, the first motor 202 can continue to rotate to drive the first crushing roller 5 to reset. Subsequently, the bolt 12 is screwed to fix the third plate 207, and in the above-mentioned manner, the position of the first crushing roller 5 is fixed. Through the above method, the adjustment work of the first crushing roller 5 is completed.

[0033] Crushing process of low-temperature resistant PBT material:

[0034] When it is necessary to crush the low-temperature resistant PBT material, connect the external power supplies of the fourth motor 14 and the second motor 13 and start them. The first motor 14 and the third motor 13 drive the second crushing roller 6 and the first crushing roller 5 to rotate respectively. Subsequently, the worker imports the PBT material to be crushed into the crusher main body 1 from above the crusher main body 1;

[0035] For the protective operation of crushing the low-temperature resistant PBT material, the worker pulls the first connecting rod 309. The first connecting rod 309 drives the convex block 306 to slide within the box body 307. At this time, the spring 308 is tightened. Subsequently, connect the external power supply of the third motor 302 and start it. The third motor 302 drives the disc 303 to rotate. The protruding part on the surface of the disc 303 fits with the slider 304. When the protruding part of the disc 303 rotates, it drives the slider 304 to move to the left (as Figure 6 ), the slider 304 drives the moving block 305 to move, and the moving block 305 drives the second connecting rod 11 to move. When the connecting rod 11 moves to the left, since the top end of the cover body 7 is connected to the crusher main body 1 through a pin shaft, when the connecting rod 11 pulls the cover body 7 to rotate, the cover body 7 rotates to close the top end of the crusher main body 1. After the cover body 7 closes the top end of the crusher main body 1, the third motor 301 is turned off. The worker separates his hand from the first connecting rod 309, and the spring 308 rebounds to drive the convex block 3066 to reset through the above method. The convex block 306 abuts against the concave part of the moving block 305 to limit its position. Through the above method, the cover body 7 is fixed. By reversing the third motor 301 in the above manner, the cover plate 7 can be driven to reset. Through the above method, the upper end of the crusher main body 1 is closed, and when crushing the PBT, the crushed PBT material will not pop out of the crusher main body 1;

[0036] The imported PBT material drops between the first crushing roller 5 and the second crushing roller 6. The first crushing roller 5 and the second crushing roller 6 rotate relatively to crush the PBT material. The crushed PBT material scatters on the surface of the conveyor belt 10. Subsequently, the conveyor belt 10 is started. The first plate body 9 is fixed to the conveyor belt 10, and the first plate body 9 can prevent the crushed PBT from scattering elsewhere. Subsequently, the external power supply of the conveyor belt 10 is connected and started. The conveyor belt 10 conveys the crushed PBT material to the second plate body 8. The surface of the second plate body 8 is inclined, and the crushed PBT material can be discharged through the second plate body 8. After the PBT material is crushed, the fourth motor 14, the second motor 13, and the conveyor belt 10 are turned off. The crushing work of the PBT material is completed in the above manner.

[0037] Although the present utility model has been illustrated and described by reference to the preferred embodiments, those skilled in the art should understand that various changes in form and details may be made within the scope of the claims.
