Abstract

The invention provides a metallized film vacuum coating device with novel evaporation crucibles. The metallized film vacuum coating device comprises a vacuum coating chamber and an evaporation drum arranged in the vacuum coating chamber. A film feeding mechanism is fixedly installed on the left side of the evaporation drum. A taking-up mechanism is fixedly installed on the right side of a cooler drum. The two evaporation crucibles are arranged below the cooler drum. Each evaporation crucible comprises a containing cavity used for containing a heated object, a heating cavity surrounding the periphery of the containing cavity, and an outer wall surrounding the heating cavity. Compared with the prior art, the metallized film vacuum coating device has the following beneficial effects that through the design of a dual-heating supply system, the temperatures of different portions of the crucibles can be controlled conveniently, the temperature of the top of each crucible is slightly higher than the material evaporation temperature, and condensation of a material can be avoided; and by accurately controlling the evaporation temperature, stability of the evaporation rate of the material is achieved.

Description

technical field [0001] The invention relates to the technical field of metallized film manufacturing, in particular to a metallized film vacuum coating device provided with a novel evaporation crucible. 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 plast...
