Slitting device and slitting method of wide coiling material

Abstract

The invention provides a slitting device for slitting a wide coiling material into a plurality of strip materials. The slitting device comprises an unwinding part, a traction part, a slitting part and a winding roller which are sequentially arranged along the conveying direction of the strip materials, wherein the slitting part comprises a slitting cutter group and a cutter roller, and a plurality of annular cutter grooves are arranged on the cutter roller. When the slitting device runs, the slitting cutter group is inserted into the annular cutter grooves and moves along the cutter grooves, and the cutter roller is in tight contact with the winding roller so that the strip materials are conveyed from the cutter roller to the winding roller. On the other hand, the invention provides a slitting method for slitting the wide coiling material into a plurality of strip materials. According to the slitting device provided by the invention, only one winding roller is needed, the structure is simple, and the operation space of the winding roller is large; a winding core is sleeved on the winding roller, the positioning, connection and unwinding operation is time-saving and labor-saving, and the slitting efficiency is greatly improved; the slitting device does not move when a narrow coil material with a thickness of less than 10cm is wound, so that the difficulty that the narrow coil material collapses is thoroughly solved; the end face of the slit coil material is neat; and each coil material does not need to be controlled by separate tension, the winding roller is simple and reliable in design, and the cost is low.

Description

technical field [0001] The invention relates to a cutting device and a cutting method for wide-width coiled materials, in particular to a cutting device and a cutting method for thin roll materials such as film and paper. Background technique [0002] Slitting device, also known as slitting machine or slitting machine, is a device that longitudinally slits wider coils into narrower strips of material. It is widely used in various industries, such as for slitting Paper, metal foil rolls (such as copper foil, aluminum foil), leather, cloth, film, film, paper, etc. [0003] Various types of slitting devices exist in the prior art. figure 1 A typical prior art slitting device 100 is schematically shown. The cutting device 100 includes an unwinding part 102 , a pulling part 104 , a cutter cutting part 106 and winding rollers 108 , 110 . The coiled material 112 with a larger width is unwound by the unwinding part 102 , pulled forward by the traction part 104 , and cut into stri...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the shortcomings of the existing slitting machine are obvious, such as (1) in order to avoid overlapping between the strips, two upper and lower winding rollers must be used, resulting in a complicated structure; (2) when the set length is reached After the shutdown and unwinding, because the wide-width coil is cut into multiple strips and wound to the upper and lower winding rollers at intervals, the operation of putting the winding core on the winding roller and positioning it is time-consuming and laborious. The operation of connecting the cut strips to the winding cores is more cumbersome; (3) narrow-width coils that are less than 10 cm are easy to shift and collapse; The misalignment of millimeters is uneven; (5) Each coil on the upper and lower winding rollers needs to have an independent tension control, and the design of the winding rollers is complicated and expensive
