With the development of market and packaging technology, the technical requirements of muffler tape manufacturers are higher and higher. The products are mainly high, large, fine and sharp, which realizes the integrated control of machinery and computer. Its large-scale microcomputer controlled automatic cutting and packaging production line is not only fast, but also can complete such processes as slitting, conveying, sealing, heat shrinking, conveying and packing with a single machine. The automatic slitting and packaging tape production line controlled by large-scale single chip microcomputer is a perfect combination of electrical control and machinery. All operating parameters are set through man-machine interface, muffler performance, torque taper in servo motor control, photoelectric probe and color mark sensor in labeling accuracy control, film breakage detection, etc., and synchronous interlock of various actions in PLC control program The technology will be applied in slitting equipment for the first time.
