The machine base 1, the driving roller 2, the driven roller 3, the synchronous belt 4, the servo motor 5, the driving wheel 6, and the photoelectric encoder are used. The device 7 and the controller 9 cooperate with each other. By sending data of the required length of the rubber strip cutting into the controller 9, the number of revolutions of the driving wheel 6 is measured by the photoelectric encoder 7 during the transmission of the rubber strip material. The controller 9 can calculate the moving distance of the rubber strip material in real time, and when the moving distance of the rubber strip material is consistent with the length required for the rubber strip cutting, the transmission of the rubber strip is stopped, and the cutting component is controlled to cut the rubber strip.
