Description

Technical Field

[0001] This utility model belongs to the field of slitting equipment technology, and more specifically, it relates to a polyester ultra-thin film slitting equipment. Background Technology

[0002] Polyester ultrathin film is an extremely thin plastic film made from polyester material. It has excellent physical, chemical and electrical properties and is widely used in many high-tech fields such as electronics, optics, packaging, and medical. In actual processing, it is usually necessary to cut the wide film master roll into multiple small-width film rolls that meet the requirements of use. This requires the use of professional slitting equipment to ensure the dimensional accuracy and edge quality of the film and meet the high requirements of downstream applications for material performance.

[0003] According to application number CN202322697788.3, ​​a film slitting machine includes: a base, a take-up roller located at one end of the base, and a feed roller located at the other end of the base. A mounting frame with a U-shaped groove is symmetrically arranged between the take-up roller and the feed roller. A cutter shaft with a blade mounted on one side wall is arranged between the two mounting frames. The blade is used for cutting the material. An end sleeve is detachably connected to both ends of the cutter shaft. A slot is formed on the circumferential side wall of the end sleeve. A plug that mates with the slot is located at the center of the bottom of the U-shaped groove. A shaft rod is fixedly installed at both ends of the cutter shaft. The end of the shaft rod away from the cutter shaft can extend through the end sleeve. External threads are provided on the outer wall of the shaft rod. A nut is fitted on the side of the end sleeve opposite to the cutter shaft and on the outer wall of the shaft rod to fix the cutter shaft to the end sleeve. This film slitting machine achieves rapid fixing and installation of the cutter shaft, improves the positional accuracy of the cutter shaft, and improves the processing quality.

[0004] Based on the above, the existing slitting equipment usually has a fixed blade spacing during use. When it is necessary to slit the film into rolls of different widths, it is often necessary to replace it with slitting rollers of different specifications. This not only increases the time for equipment replacement and debugging, but also increases the cost of equipment use and limits production efficiency and flexibility. Utility Model Content
