High-precision slitting and rewinding device for high-barrier thermal shrinkage film production

Abstract

The invention discloses a high-precision slitting rewinding device for high-barrier thermal shrinkage film production. The high-precision slitting rewinding device comprises a base and a box body, wherein an unwinding roller and a winding roller are symmetrically and rotationally arranged on the left side and the right side of the interior of the box body, two first guide rollers are rotationallyinstalled at the part, on the right side of the unwinding roller, inside the box body, two second guide rollers are rotationally arranged at the parts, on the left side of the winding roller, inside the box body, two through holes are symmetrically formed in a top plate of the box body, and two parallel rollers are symmetrically and rotationally arranged at the parts, on the inner sides of the twothrough holes, of the upper side of the top plate of the box body. According to the high-precision slitting rewinding device, the first guide rollers, the parallel rollers and the second guide rollerare arranged in a staggered mode, so that a shrinkage film in the moving process is tightened, the shrinkage film is kept in a tight state in the cutting process, then the cutting effect is improved,and then the cutting precision is improved; and the height of lifting frames is adjusted by rotating second screw rods, so that pressing rollers are tightly attached to the shrinking film on the parallel rollers, and it is ensured that the shrinking film is kept tight during cutting.

Description

technical field [0001] The invention relates to a slitting and rewinding machine, in particular to a high-precision slitting and rewinding device used for the production of high-resistance thermal shrinkage films. Background technique [0002] Slitting machine is a kind of mechanical equipment that cuts wide paper, mica tape or film into multiple narrow materials. It is often used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The slitting machine is mainly used for: mica tape, paper, insulating material and film slitting, especially suitable for narrow tape slitting; slitting machine is a large roll of paper, film, non-woven fabric, aluminum foil, mica tape, etc Pre-press and post-press equipment for cutting thin materials into small rolls of different widths, commonly used in papermaking machinery and printing and packaging machinery, including racks and square roll devices, guide rollers, slitting devices, and rewinding devices in...

AI Technical Summary

Problems solved by technology

[0003] Since the shrink film has the characteristics of light weight, delicate material and thin thickness, this requires the rewinding and slitting machine to have a stable and fine tension. When the shrink film is cut, because the required tension becomes smaller, this requires more fine And stable tension, while the existing equipment is simple in design, poor in tension fineness and stability
