Description

Linkage type brushing device, adhesive tape printing production line and automatic ink adding method

Technical Field

The invention relates to a brushing device required by screen printing, in particular to a linkage type brushing device, an adhesive tape printing production line and an automatic ink adding method.

Background

Screen printing is a common printing method. For example, LOGO and the like are required to be printed on the basis of a common box sealing adhesive tape, so that the adhesive tape is required to be printed, a screen plate is required to be used for the adhesive tape printing, and the screen plate is used for printing by utilizing the basic principle that the meshes of image-text parts of a screen printing plate can penetrate ink and the meshes of non-image-text parts can not penetrate ink. When printing, ink is poured into one end of the screen printing plate, a scraper plate is used for applying a certain pressure to the ink position on the screen printing plate, meanwhile, the scraper plate moves towards the other end of the screen printing plate at a constant speed, and the ink is extruded onto a printing stock from meshes of the image-text part by the scraper plate in the moving process. In view of the related art in the above, the present inventors consider that the following drawbacks exist: in the use process of the existing brushing device, ink is easy to be accumulated at one end of a screen printing plate, so that the color depth of the ink on a printing stock is inconsistent after printing, namely the printing effect is inconsistent.

For this reason, the present inventors searched 19 patent documents based on the search keyword "classification number ═ (B41) AND name, abstract, claim + ═ reciprocating AND moving AND scraping brush AND screen AND printing AND ink (uneven or piled or average or uniform))". Among them, the CN201220423554.9 screen printing device solves the cleaning problem of the screen. CN201721526084.8 is a screen printing device, in which a second ink scraping is added to solve the problem of color difference during printing.

The present inventors have considered it necessary to develop a new squeegee device to solve the problem of ink uniformity in screen printing.

In addition, at present, during screen printing, ink is often added manually by an operator, and is also added automatically by a machine. For example, 30 patent documents are searched for based on the search keyword "title, abstract, claims + (screen and printing and ink and automatic and adding)". The control systems in these patent documents do not implement closed loop control, but only mechanical inking. Therefore, it is necessary to solve the problem of adding ink together.
