[0002] The slitting machine is used to unwind, slitting and rewind the steel strip into coils of required width, and rewind the slit coils.

[0003] A Chinese patent discloses a winding device for a longitudinal shearing machine, with the publication number CN219751429U, which includes a base provided on the surface of a base plate, an insert block provided in the base plate, and rotating shafts provided at both ends of the winding drum; the beneficial effect is: the winding device for a longitudinal shearing machine proposed in the present invention, when the winding device is to be installed on the base plate, first align the insert block with the slot provided on the base plate and insert it, then align the pin with the socket provided on the surface of the base plate and insert it, at this time the screw head enters the screw hole provided on the surface of the baffle, and finally the nut is tightened to fix the winding device on the base plate, this installation method is convenient and fast, and the disassembly is simple. At the same time, the utility model reduces the vibration generated by the winding device of the longitudinal shearing machine during operation through the deformation of the shock-absorbing pad and the spring, thereby ensuring that the longitudinal shearing machine can accurately cut the metal.

[0004] However, there are still some disadvantages: the device uses a reel to reel the coil, but after the coil is cut, the device does not fix the coil, which can easily cause the coil to shift between layers after cutting, causing the coil to spread. To solve this problem, we proposed a reeling device for slitting equipment to solve this problem. Utility Model Content
