A polyethylene plastic film laser slitting component

Abstract

The invention belongs to the technical field of plastic film production, and particularly relates to a polyethylene plastic film laser cutting assembly. The polyethylene plastic film laser cutting assembly comprises a raw material roller, a transmission roller, a separation rod, a winding roller, two or more cutting devices and a rack. The raw material roller is located at the foremost end of therack. The transmission roller is located on the right side of the raw material roller. The cutting devices are located on the upper left portion of the separation rod. A polyethylene plastic film canbe cut into multiple parts through the cutting devices. The separation rod is located on the right side of the transmission roller and used for separating the cut polyethylene plastic film parts, andsubsequent winding is facilitated. The winding roller is located on the right side of the separation rod and used for winding the cut polyethylene plastic film parts in a separated mode, and thus collecting is achieved. The section of the rack is in a U shape, the raw material roller, the transmission roller and the winding roller are rotationally connected with the rack, and a first motor is arranged on one side of the winding roller. According to the polyethylene plastic film laser cutting assembly, precise movement of a laser can be achieved, and thus the film is cut highly precisely.

Description

technical field [0001] The invention belongs to the technical field of plastic film production, in particular to a polyethylene plastic film laser cutting assembly. Background technique [0002] With the improvement of people's living standards, more and more people pay attention to the packaging of various products. With the prosperity of the packaging industry, the demand for various plastic films such as BOPP, BOPA, CPP, GCPP and other films for packaging has increased significantly. The slitter is a kind of cutting wide film, mica tape or paper into multiple narrow Mechanical equipment for web materials, 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 slitting of narrow tape (insulating material, mica tape, film, etc.); the cutting principle of the traditional film slitting machine is two The cutti...

Problems solved by technology

[0004] In the above comparative literature, the movement of the laser is realized by the sliding of the roller on the slide rail, thereby controlling the shape of the cutting edge, but in this solution, the movement is realized through friction between the roller and the slide rail, so that the rollers are unified on the slide rail. Slipping affects the movement accuracy of the laser, resulting in poor shape accuracy of the cutting edge and reducing the quality of the film
