Vapor deposition and thin film collecting mechanism

Abstract

The invention provides a vapor deposition and thin film collecting mechanism which comprises a slitting support and a take-up support. A transmission device and a cutting device are arranged on the slitting support, a take-up roller is arranged on the take-up support, the transmission device comprises a receiving rotary shaft, a straight rolling rotary shaft and a cutting rotary shaft, the cutting device comprises a cutter shaft fixing support, a cutter shaft, a cutter rest and a cutter, a gap is formed in the middle of the outer end of the cutter rest, and the cutter is fixed in the gap through a fixing pin and can swing around the fixing pin. The vapor deposition and thin film collecting mechanism further comprises an elastic sheet arranged between the back of the cutter and the edge bottom of the gap and capable of making the cutter swinging and rebounding, wherein the elastic sheet is fixed to the edge bottom of the gap. The vapor deposition and thin film collecting mechanism has the following advantages that the elastic sheet is mainly used for playing a shock absorption and buffering effect between the cutter and the edge bottom of the gap of the cutter rest, a slitting tension is always kept at appropriate strength during thin metal film slitting, and thin metal films are thoroughly slit.

Description

technical field [0001] The invention relates to the technical field of metallized film manufacturing, in particular to an evaporation film receiving mechanism. Background technique [0002] With the development of modern film science and technology, especially the large-scale industrial application of metallized films for capacitors and packaging, a huge film production and film processing industry has been formed in the world. The demand for household appliances, electrical appliances, electronic products, and packaging products is increasing rapidly, which leads to an increasing demand for metallized films, resulting in an increasingly urgent demand for high-efficiency, high-performance, and multi-functional film evaporation equipment. [0003] Thin film evaporation equipment integrates multidisciplinary technologies such as machinery, vacuum, coating, refrigeration, and automatic control. It evaporates aluminum or zinc onto plastic film substrates through high-temperature...

AI Technical Summary

Problems solved by technology

[0004] During the whole coating process, the width of the film base material remains unchanged, and they are all individually unwound one-to-one, that is, the width of the unrolled film base material is the same as the width of the film base material wound up during rewinding. Work efficiency is limited

[0005] In the prior art, the slitting knife is directly fixed on the knife holder by bolts, which does not have a shock-absorbing and buffering effect. Slitting the metal film may cause insufficient tension of the metal film and incomplete slitting of the metal film.
