Coating equipment, method and coating mechanism for coating slurry on metal substrate

Abstract

The invention discloses a coating device, a method and a coating mechanism for coating slurry on a metal base material. The roll mechanism, the coating mechanism includes a feeding box for containing the slurry, an anilox roller, a glue roller with a rubber layer on the surface, a scraper and an air cylinder, wherein the feeding box, the anilox roller and the glue The pressure roller is installed vertically from bottom to top; the rubber pressure roller and the anilox roller rotate in the opposite direction, and a certain contact pressure is formed between the rubber pressure roller and the anilox roller, which is used for processing coated metal substrates. The air cylinder is installed at both ends of the rubber pressing roller and is used for adjusting the height of the rubber pressing roller. When the metal substrate is coated by the present invention, the problems in the prior art such as uneven coating, bubbles, wrinkling or creases on the metal substrate are overcome. Moreover, the structure is simple and the method is easy to operate.

Description

technical field [0001] The invention relates to the technical field of film coating, in particular to a coating equipment, method and coating mechanism for coating slurry on a metal substrate. Background technique [0002] With the development of the electronics industry towards high-density packaging and miniaturization, materials with special functions, such as conductive materials, insulating materials, thermal conductive materials and antistatic materials used in the manufacture of high-end circuit boards, often need to be coated before use. At present, coating methods include gravure printing technology, spray printing technology, silk screen technology, extrusion molding technology and so on. [0003] At present, the widely used gravure printing technology mainly adopts high-speed gravure printing machine, and the coating mechanism uses two anilox rollers with a diameter greater than or equal to 200 mm and a hard pressure roller for coating. This type of coating mecha...
