AI Technical Summary

Technical Problem

The existing Mylar film cutting device has an adjustable blade spacing, which limits its applicability. Furthermore, the integrated structure of the blade and drive shaft results in high maintenance costs and poor limiting effect, affecting cutting accuracy.

Method used

A Mylar film cutting device with adjustable cutting blade spacing was designed. Through the detachable limiting component and cutting component, the worn cutting blade can be replaced independently, and the Mylar film can be precisely positioned in combination with the feed and feed-out limiting rollers.

Benefits of technology

It enables flexible adjustment of the cutting blade spacing, reduces maintenance costs, improves cutting accuracy and applicability, and ensures the stability of Mylar film during the cutting process.

Abstract

The utility model discloses a Mylar film cutting device which comprises a supporting table, a limiting assembly is arranged on the inner side of the supporting table, a cutting assembly is arranged at the upper end of the supporting table, a fixed blocking frame is unlocked by unscrewing a locking screw, and therefore the cutting width of two sets of cutting knives can be adjusted in a matched mode according to the cutting requirement. When a fixed screw rod is unscrewed and disassembled, a limiting cover can be disassembled and taken down, and at the moment, an electric telescopic rod is controlled to drive a bearing seat to descend, so that a cutting knife can be moved backwards, disassembled and replaced, and first limiting baffle rings are symmetrically arranged on the front side and the rear side of the annular side face of a feeding limiting roller in a sleeving mode; according to the Mylar film cutting machine, the feeding limiting roller is symmetrically sleeved with the first limiting baffle rings, so that the feeding limiting roller can limit and guide an uncut Mylar film, the front side and the rear side of the annular side face of the discharging limiting roller are symmetrically sleeved with the second limiting baffle rings, the discharging limiting roller can limit and guide the cut Mylar film, and therefore the phenomenon that the Mylar film deviates in the cutting process is avoided; therefore, the cutting precision of the mylar film is ensured.
