Abstract

The invention relates to the technical field of coating, in particular to a slit coating die, comprising a die body and a negative pressure component, the die body is provided with a coating lip; the negative pressure component includes a negative pressure generating mechanism and a The negative pressure passage connected to the negative pressure generating mechanism, the negative pressure passage is located on the same side of the coating lip, and is arranged in the same direction as the coating lip. The coating lip is coated and discharged, and the negative pressure generating mechanism works, so that the negative pressure passage generates negative pressure. After the negative pressure channel forms negative pressure, since the negative pressure channel is located on the same side of the coating lip and set in the same direction, the coating lip can also form a negative pressure during the coating process, so as to realize the coating lip Vacuum coating can prevent external influences during the coating process, so that the coating density of the thin layer is uniform and the coating quality of the thin layer is effectively improved.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a slit coating die head. Background technique [0002] The coating machine is mainly used for the surface coating process of film, paper, etc. The coating machine is to coat the rolled substrate with a layer of glue, paint or ink with special functions, and then wind it up after drying. It adopts a special multi-functional coating die head, which can realize various forms of surface coating production. The coating machine is composed of a winding section, a coating section, a baking section, and an unwinding section. The coating die is installed on the coating section of the coating machine, and the slurry is delivered to the coating die by the conveying system. Coating dies are used to spray the slurry supplied by the delivery system directly onto the substrate. [0003] In the prior art, there is a slit coating die, which consists of an upper die, a lower die, and a gasket ar...
