Strip film plating machine

Abstract

The invention provides a strip film plating machine, which comprises at least one film plating vacuum chamber, and a coiled material unreel mechanism and a coiled material take-up mechanism which are positioned outside the film plating vacuum chamber. The strip film plating machine is characterized in that: a vacuum channel for at least one strip is formed between the film plating vacuum chamber and the coiled material unreel mechanism; a vacuum channel for at least one strip is formed between the film plating vacuum chamber and the take-up mechanism; and the vacuum channels each consist of at least one group of arc-shaped narrow silt damping mechanisms formed by two arc-shaped cavities and two rollers positioned in the two arc-shaped cavities and a vacuum lock with a vacuum aspirating chamber. In the strip film plating machine, the coiled material unreel mechanism and the coiled material take-up mechanism are arranged outside the vacuum chamber; the vacuum lock and a narrow silt damping channel are hermetic and reliable and have long service life, and the manufacturing cost of the equipment is low; and the strip film plating machine can perform continuous production and perform monolayer or multilayer film plating on surfaces of plastic films and metal sheets, and the surfaces of the obtained plating films have compact microstructures and are smooth.

Description

Technical field: [0001] The invention relates to a strip coating machine, in particular to a strip coating machine with an arc-shaped narrow slit damping mechanism. Background technique: [0002] The strip is coated with functional film in the coating vacuum chamber. If the coil unwinding mechanism and winding mechanism are placed in the vacuum chamber, it is necessary to set the strip in and out between the coating vacuum chamber and the coil unwinding mechanism and winding mechanism. Through the vacuum channel, the traditional vacuum channel is composed of a linear slit damping mechanism and a vacuum pumping chamber. In order to ensure the vacuum degree in the coating vacuum chamber, the length of the linear slit damping mechanism should be increased as much as possible. And the effect is not good, it is difficult to ensure the vacuum degree in the coating vacuum chamber with few and low-power vacuum pumps, which is unfavorable for the economical operation of the vacuum pu...
