The spool belt 9 is connected between the first spool 6 and the second spool 8, it is a special transmission belt, its characteristic is that it has a herringbone-shaped tooth pattern, this design can improve the transmission efficiency and reduce the sliding. The spool belt 9 transmits the power of the second spool 8 to the first spool 6 through meshing between the two spools, and then transmits it to other parts of the cutting device.

[0045] The working principle and use process of the utility model: first, place the raw rubber on the rectangular table 2, ensure that the raw rubber is flat and placed in the cutting area. Start the motor 7, ensure that all power transmission components such as the spool belt 9, the first spool 6, the second spool 8, etc. are in normal operation. The falling of the blade 22 is controlled by the air cylinder 21, and the blade 22 is moved by the connecting block 18 and the telescopic rod 19. The spring 20 is used to keep the blade 22 lifted in the non-working state to avoid damage to the raw rubber in the non-cutting state. The movement of the light rod 16 and the base 17 is controlled by the connecting block 18 to achieve precise positioning and cutting of the blade 22. When the blade 22 contacts the raw rubber, the air cylinder 21 pushes the connecting block 18 and the blade 22 downward to cut. During the cutting process, the rotating rod 4 and the disc 5, as well as the connecting seat 10 and the round rod 11, work together to guide the raw rubber or adjust the cutting position. The circular roller 12 and the conveying belt 15 are used to process the raw rubber before and after cutting, such as pressing or conveying the raw rubber. After cutting is completed, the air cylinder 21 stops pushing, and the blade 22 returns to the lifting position, ready for the next cutting. Clean the working area and prepare to process or collect the cut raw rubber.
