Abstract

The invention relates to the technical field of slitter guide rollers, and discloses a thermoplastic polyurethane (TPU) film slitter guide roller mechanism. The TPU film slitter guide roller mechanismcomprises a machine body; the front portion of the machine body is rotatably connected with a feeding roller; the surface of the feeding roller is fixedly connected with a film roll body; the interior of the machine body is rotatably connected with a knife roller; an adjusting mechanism is arranged at the position, located behind the knife roller, of the machine body; the surface of the adjustingmechanism is provided with a guide mechanism; an upper take-up roller and a lower take-up roller are rotatably connected to the portion, located on the rear portion of the adjusting mechanism, of themachine body; and the upper take-up roller is located above the lower take-up roller. According to the TPU film splitter guide roller mechanism, by installing the adjusting mechanism and the guide mechanism, the effect of adjusting the tension degree of the guide roller is achieved through mutual operation of all structures in the adjusting mechanism and the guide mechanism, and meanwhile, the effect that split film bodies different in thickness can be pressed is achieved when the tension degree is adjusted, thereby achieving the effect of guiding the film bodies different in cutting width tobe conveyed.

Description

technical field

[0001] The invention relates to the technical field of slitter guide rollers, in particular to a TPU film slitter guide roller mechanism. Background technique

[0002] The slitting machine is a kind of mechanical equipment that cuts wide paper, mica tape or film into multiple narrow-width materials. It is often used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The slitter is mainly used in non-woven fabrics. Slitting of cloth / mica tape, paper, insulating material and various film materials, especially suitable for slitting of narrow tape (non-woven fabric, paper, insulating material, mica tape, film, etc.), TPU film is thermoplastic TPU elastomer It is made of MDI containing NCO functional group and POLYOL and 1.4BG containing OH functional group through extrusion and mixing. Due to its good elasticity, good physical properties and good mechanical strength, it is widely used in injection, Processing methods such as...
