The second sprocket (205) drives the first gear (501) of the synchronous transmission mechanism (5) and the third sprocket (901) of the chain transmission mechanism (9); Step2: Place the flexible rubber sheet to be cut on the feeding roller (302) of the feeding device (3), and push it into the top pressing roller (304) and the feeding friction groove roller ( 303) between; Step3: Drive the fourth sprocket (903) synchronously through the third sprocket (901) and the second chain (902), and then drive the feed friction groove roller (303) by the fourth sprocket (903), and then pass the feed The cooperation between the material friction groove roller (303) and the top pressing roller (304) pushes the flexible rubber plate into between the bottom hob assembly (808) and the top hob assembly (807); Step4: The second gear (502) will be driven by the first gear (501), and then the top hob assembly (807) will be driven by the second gear (502); then the top hob assembly (807) and the bottom hob assembly ( 808) two sets of the first hob (804) and the second hob (806), which are matched up and down, perform cutting and matching, and then cut the rubber sheet; Step5: During the cutting process, according to the thickness of the rubber sheet, adjust the height position of the spindle mounting sleeve (704) by adjusting the lifting adjustment structure (7) to adjust the bottom hob assembly (808) and the top hob assembly (807) The distance between the matching hob, thus ensuring the best cutting effect.
