Slitting device used for thin film slitting machine

Abstract

The invention provides a slitting device used for a thin film slitting machine. The slitting device comprises two opposite fixed plates, a first transmission guide wheel, a cutter groove wheel transmission shaft and a slitting shaft which are parallel are arranged between the two fixed plates, the first transmission guide wheel and the cutter groove wheel transmission shaft are the same in height,the slitting shaft is arranged above the cutter groove wheel transmission shaft, cutter groove wheels are arranged at the two ends of the cutter groove wheel transmission shaft, and are arranged on the cutter groove wheel transmission shaft in a sleeving manner, multiple grooves are formed in the cutter groove wheel transmission shaft, and the cutter groove wheels are clamped in the grooves; twocutter rests are arranged on the slitting shaft in a sleeving manner, and a slitting cutter is arranged on each cutter rest in an erected manner. The cutter groove wheels arranged on the cutter groovewheel transmission shaft in a sleeving manner are used, the cutter groove wheels can support the edge of the thin film, the phenomenon that the edge of the thin film is suspended is avoided, it is ensured that a cutter can cut into the edge portion of the film, the cutter sliding phenomenon can be avoided, narrow edge can be cut, and thin film waste is reduced.

Description

technical field [0001] The present application relates to the field of film processing equipment, in particular to a cutting device for a film cutting machine. Background technique [0002] In actual production, there are often certain requirements for the size of the film used for packaging to meet the packaging of different products in different industries. A film slitter is a mechanical device that cuts a wide-width film into multiple narrow-width materials, and is often used in the packaging industry. The working principle of the film slitting machine is as follows: the metallized film raw material released from the unwinding mechanism enters the slitting mechanism through the flattening roller, tension detection roller and empowering roller, and the raw material is collected by the winding mechanism after slitting. Rolled into standard film rolls. [0003] However, when the slitting device of the existing film slitting machine slits the film, because the material of t...

Problems solved by technology

[0004] This application provides a cutting device for a film slitting machine to solve the problem that when the existing cutting device of a film slitting machine cuts a film, because the material of the film is relatively soft and thin, the edge of the film is suspended. The slitting knife will not be able to cut the film, resulting in a slippery knife, causing the film after slitting to fail to meet the required specifications, which will affect the quality of the product
