Scraper device for coating

Abstract

The invention discloses a scraper device for coating. The scraper device comprises a scraper component, an x-axis regulating device, a left and right movement sliding rail and a z-axis regulating device, wherein the scraper component is arranged on the x-axis regulating device and is used for scraping off the excess glue on a coating mesh roller; the x-axis regulating device is arranged above theleft and right movement sliding rail and is used for enabling the scraper component to move forwards and backwards; the left and right movement sliding rail is arranged above the z-axis regulating device and is used for driving the scraper component to move left and right; and the z-axis regulating device is used for driving the scraper component to move up and down. In the scraper device, the scraper component can move up and down through the z-axis regulating device, therefore the regulating range of the scraper component is expanded, the scraped glue is prevented from forming a scraper line, and the coating weight is controlled.

Description

technical field

[0001] The present application relates to the technical field of coating, in particular to a scraper device for coating. Background technique

[0002] Coating technology is widely used in the coating of film and other substrates and composite packaging. Coating is mainly realized by a coating machine, which is mainly used for the surface coating process of the film. The coating machine is to coat the film with a certain amount of glue with specific functions. In actual production, it often occurs that there is excess glue on the coating screen roll.

[0003] In the existing scraper equipment, the impurities in the scraped glue are often difficult to discharge, forming knife lines, and the amount of coating cannot be well controlled, which affects product quality. Contents of the invention

[0004] The purpose of the present application is to provide a doctor blade device for coating, so as to solve the problem in the prior art that knife lines are formed ...

Examples

Embodiment Construction

[0029] Refer to attached figure 1 The embodiment of the present application is described, a scraper device for coating, the scraper device includes a scraper member 1, an x-axis adjustment device 2, a left and right movement device 3 and a z-axis adjustment device 4;

[0030] The scraper member 1 is arranged on the x-axis adjustment device 2, and is used to scrape off excess glue on the coating anilox roll 6;

[0031] Specifically, uneven gluing often occurs in the production process of the film, which requires a scraper component 1 to scrape the gluing evenly. The film scrapes off the glue on the coating net roll 6 by scraping blade part 1 on the coating net roll 6 . In the prior art, the scraped-off glue impurities are not easy to be discharged from the scraper, forming knife lines and affecting product quality. For example, laser paper is a kind of material with the same effect as grating, so when producing laser paper, the formed knife line has a great influence on the p...
