Description

Technical Field

[0001] The invention relates to the technical field related to textile printing, and in particular to a scraping auxiliary device for a digital printing machine. Background Art

[0002] Textile printing is a process of limited dyeing on a predetermined area of ​​fabric, which includes preparing color paste, developing and fixing color, and adding thickener to limit the color paste to a predetermined range of the fabric. Digital printing uses digital technology for printing. The principle is similar to that of traditional inkjet printers and is not limited by the printing color. However, digital printing is difficult to print directly on black fabrics. To solve this problem, you can choose to scrape a layer of base paste at the location to be printed, and then use a digital printing machine for printing. However, traditional scraping machines are difficult to use with digital printing machines, so there is a special need for a scraping auxiliary device for digital printing machines.

[0003] However, in the existing scraping auxiliary device, the printing paste remaining on the scraper surface affects the effect of subsequent scraping, thereby affecting the quality of printing. The long-term adhesion of printing paste on the scraper surface may even affect the service life of the scraper. In addition, due to the different thickness of clothes, the pressure between the scraper and the screen may change, thereby affecting the scraping effect of the scraper and the quality of printing.

[0004] To solve the above problems, after searching, a patent with announcement number CN109056391A discloses a digital transfer printing method, which proposes "including the following steps: preparing digital white slurry, selecting colored cloth dyed with reactive dyes matching the white slurry in the step, pre-printing alignment, slurry color printing, pressing or baking; the process flow adopted by the present invention is white slurry-color printing-drying-pressing / baking, which omits the step of restoring dark cloth to white, simplifies the process flow, and at the same time, the color printed on the substrate has high brightness and strong color fastness; in addition, the present invention simplifies the positioning section of the silk screen during printing to the close proximity of the screen locator and the positioning code by arranging a screen positioner on the silk screen printing platform and a proximity sensor on the digital printing machine, thereby simplifying the positioning operation of the silk screen and improving the printing accuracy". Although the positioning operation of the silk screen can be simplified by the proximity sensor and the printing accuracy is improved, the printing slurry attached to the scraper surface cannot be cleaned, and the pressure between the scraper and the screen cannot be controlled.
