Problems solved by technology

[0005] The purpose of the present invention is to solve the defects in the prior art and provide a wire feeding mechanism of a vacuum coating machine to solve the defects caused by the deposition and condensation of evaporated materials at the evaporation port of the crucible and the splashing of materials to the film caused by uneven heating inside the crucible. , the end of the aluminum wire is constrained by the limiting part, which can effectively prevent the end of the aluminum wire from sliding on the heating source, thereby preventing the generated aluminum slag from splashing on the aluminized film and causing damage to the aluminized film, effectively ensuring the aluminized film production quality

Abstract

The invention provides a wire feeding mechanism of a vacuum film plating machine. The wire feeding mechanism comprises a wire supplying disc, a wire feeding mechanism body, a wire discharging nozzle and a heating crucible. The wire discharging nozzle extends into the heating crucible. The wire feeding mechanism body comprises a wire feeding rotating shaft, multiple wire feeding rolls and a power device, wherein the wire feeding rolls are fixed to the wire feeding rotating shaft; the power device provides power for the wire feeding rotating shaft; and the two ends of each wire feeding roll are provided with a wire protection sleeve and a wire pressing block. The wire feeding mechanism has the beneficial effects that the wire feeding speed of each evaporation boat is controlled through different diameters of the wire feeding rolls, thus the wire feeding amount is controlled; square resistance uniformity of a product is improved; product quality is improved; by arranging the wire pressing blocks, a metal wire in the conveying process can be located, the tail end of the aluminum wire can be constrained, and thus the tail end of the aluminum wire can be effectively prevented from sliding on a heating source; furthermore, the situation that generated aluminum chippings splash to an aluminum-plated film to damage the aluminum-plated film is prevented; and production quality of the aluminum-plated film is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of metallized film manufacturing, in particular to a wire feeding mechanism of a vacuum coating machine. 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 hig...
