Coating machine

Abstract

The invention discloses a coating machine, which includes, in a successively connection manner, an unreeling mechanism, a drawing mechanism and a coating apparatus, and also includes a corona apparatus arranged between the drawing mechanism and the coating apparatus and used for performing electric shock treatment to a cloth which is conveyed through the corona apparatus by the drawing mechanism. In the coating machine, the corona apparatus is arranged between the drawing mechanism and the coating apparatus, so that by means of the corona treatment to paper or fabrics before film plating, gold blocking or printing and dyeing, the adhesive ability of a cloth can be improved and further the adhesive ability of the cloth in a coating process is enhanced, by that a processed product is uniform. The coating machine can increase an adhesive area, can avoid the problems of mis-plating of a film or mis-printing and the like, can avoid second-time coating, is reduced in cost and is improved in production efficiency.

Description

technical field [0001] The invention relates to the technical field of coating machines, in particular to a coating machine. Background technique [0002] Existing coating machines for laser transfer, bronzing, optical film, protective film, electronic film and dielectric exchange film, many domestic printing and packaging machinery enterprises use coating compound equipment, the coating types and squeegee methods are relatively single, coating The application of technology is also greatly restricted. No matter what kind of coating compound equipment, the key part is the coating head, and the coating scraping method used by the coating head will directly affect the quality and adhesion of the coating. In addition to the influence of the coating head of the coating knife on the quality of the coated cloth, the degree of adhesion and adhesion of the cloth also have an impact on the cloth dyeing and processing into colored paper or processing into optical film, protective film,...

Problems solved by technology

[0002] Existing coating machines for laser transfer, hot stamping, optical film, protective film, electronic film and medium exchange film, many domestic printing and packaging machinery enterprises use coating compound equipment, the coating types and squeegee methods are relatively single, coating The application of technology is also greatly restricted. No matter what kind of coating compound equipment, the key part is the coating head, and the coating scraping method used by the coating head will directly affect the quality and adhesion of the coating. In addition to the influence of the coating head of the coating knife on the quality of the coated cloth, the degree of adhesion and adhesion of the cloth also have an impact on the cloth dyeing and processing into colored paper or processing into optical film, protective film, bronzing, etc. Significantly, especially affecting the homogeneity of the resulting product
