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 w

Embodiment 1

[0031] like Figure 2A As shown, it shows a schematic structural diagram of a cutting device according to an embodiment of the present invention. The cutting device 200 includes an unwinding part 202 , a pulling part 204 , a cutting part, an exhaust roller 220 and a winding roller 208 . A wide web 212, such as a plastic film with a thickness of about 0.01 to 0.15 mm and a width of about 0.5 to 2.5 m, usually in the form of a roll, is transported from the unwinding section 202 to the slitting section (such as indicated by arrow P). It should be understood that, for the sake of brevity, the traction unit 204 is only shown as one traction device. In actual operation, those skilled in the art can configure multiple traction devices in different positions according to actual needs, so as to realize wide-width coil transmission The pulling effect in the process, these multiple pulling devices can be collectively referred to as the pulling part of the present invention. In additio...

Embodiment 2

[0039] image 3 An exemplary structure of a slitting device according to another embodiment of the present invention is shown. The cutting device 300 includes an unwinding part 302 , a pulling part 304 , a cutting part, an exhaust roller 320 and a winding roller 308 . A wide web 312, such as a paper with a thickness of about 0.01 to 0.15 mm and a width of about 0.5 to 2.5 m, usually in the form of a roll, is transported from the unwinding part 302 to the slitting part via the traction part 304 (as shown by the arrow P shown). It is basically the same as the solution described in Embodiment 2, except that the wide web 312 is transported to the cutting section in the opposite direction (counterclockwise) to that shown in Embodiment 2, and the cutting section cuts it into multiple The strip, the strip is directly transported by the knife roller 330 to the exhaust roller 320 without suspended transmission, and then directly transmitted to the winding roller 308 through the exhau...

Embodiment 3

[0041] Figure 4 An exemplary structure of a slitting device according to another embodiment of the present invention is shown. The cutting device 400 includes an unwinding part 402 , a pulling part 404 , a cutting part, a winding roller 408 and an exhaust roller 420 . A wide web 412, such as a film with a thickness of about 0.01 to 0.15 mm and a width of about 0.5 to 2.5 m, usually in the form of a roll, is transported from the unwinding part 402 to the slitting part via the traction part 404 (as shown by the arrow P shown). The cutting part includes a cutting knife set 406 and a knife roller 430 . The difference from Embodiment 2 is that after the wide web 412 is transported to the cutting part, it is cut into multiple strips by the cooperation of the cutting knife group 406 and the knife roller 430, and the multiple strips are cut into strips. Transfer directly to take-up roll 408. The strip is continuously wound and pasted on the winding roller 408 without detaching fr...

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...
