Coating machine

Abstract

The invention discloses a coating machine which comprises a rack (1), a glue box (2), a glue spreading roller (3), a scraper blade (4), a motor (5), a group of transmission rollers (6), a drying box (7) and a cooling box (8), wherein a convex block (11) is arranged on one side of the scraper blade (4); the scraper blade (4) is movably mounted on the rack (1), and is located on one side of the glue spreading roller (3); a cylindrical cam (12) is arranged on an output shaft of the motor (5); and the motor (5) drives the scraper blade (4) to do reciprocating movement through the cooperation of the cylindrical cam (12) and the convex block (11). The coating machine has the advantages that an electrothermal wire is arranged in the glue box, so that the temperature of glue is guaranteed, and the glue spreading roller can roll up the glue conveniently and coat the glue to a workpiece; by the scraper blade capable of moving back and forth, the phenomenon that the glue spreading roller is partially worn due to long-time fixed scraping of the glue spreading roller is prevented, so that the glue spreading quality is improved; and drying and cooling are carried out in sequence, so that a thin film is at normal temperature during winding, and the winding quality is improved.

Description

technical field [0001] The invention relates to the technical field of plastic film surface coating, in particular to a coating machine. Background technique [0002] At present, films are more and more widely used in our production and life. The plastic films used for electronic product packaging need to be treated with gluing, corona and electrolysis to prevent static electricity from damaging electronic products. The existing film gluing device applies gluing to the film through the gluing roller. The gluing roller is provided with a scraper to make the glue on the gluing roller uniform. However, the scraper is fixed against the gluing roller for a long time to scrape glue It is easy to cause damage to the gluing roller, and it is easy to cause uneven smearing during gluing, which reduces the production quality of the film. After the gluing is completed, the film is dried and rolled. The high temperature of the film after winding is easy to cause deformation. Can not mee...
