[0002] The slitting machine, also known as the slitting line, slitting machine, and slitting machine, is a name for metal slitting equipment. Its purpose is to shear the metal strips longitudinally and rewind the slit narrow strips into rolls. Its advantages are easy operation, high cutting quality, high material utilization rate, and stepless cutting speed regulation.

[0003] After searching the announcement number: CN214978132U, a longitudinal shearing machine mechanism which is easy to process is disclosed. The longitudinal shearing machine mechanism which is easy to process includes two support plates. The upper parts of the adjacent ends of the two support plates are provided with sliding grooves, and the side end of the support plate on one side is fixedly connected with a storage plate; and a convenient shearing mechanism. The convenient shearing mechanism is arranged between the adjacent ends of the two support plates to realize adjustable and convenient shearing of the material. This application solves the problem that the use process is not convenient enough.

[0004] However, in this application, two sets of moving blocks move on the first screw rod and the second threaded rod to adjust the position of the electric cutting knife. However, some fine distances cannot be accurately controlled by the rotation of the first screw rod and the second screw rod, and the first screw rod and the second screw rod need to be rotated multiple times, which is relatively cumbersome.

[0005] Therefore, we designed a reel expansion and contraction device for high-speed thin strip slitting machines. Utility Model Content
