Problems solved by technology

[0002] At present, the mechanized screen frame overprinting adopts a scraper assembly, which is composed of a scraper and an ink return knife (two scrapers), and the two are set at a certain angle. Use the scraper to scrape the printing ink, and then return the ink through the ink return knife. The scraper assembly moves horizontally on the work surface. The scraping or ink return is switched by the rise or fall of the two scrapers. There are many parts in the scraper assembly, and the installation requires coordination. , complex electromechanical control

Embodiment 1

[0030] Example 1: See Figure 1 to Figure 5 , a scraper 3 with a fixed structure, including a knife seat 31 at both ends and a scraping knife 32 between the knife seats, the scraping knife is connected with the knife seat and moves back and forth along the worktable to complete printing. The knife seat 31 is a fixed seat, which includes a base 311, a lifting cylinder 312, and a lifting rod 313. The lifting cylinder 312 is installed on the base 311, and the cylinder pushes the lifting rod 313 to move up and down. The bottom end of the lifting rod 313 is connected to the scraping tool 32, The squeegee 32 includes a pointed squeegee 3200 , and the angle between the squeegee 3200 and the working surface remains unchanged during squeegee printing and ink return. Lifting cylinder 312 is provided with piston rod and lifting rod 313 and is arranged in parallel, and the top of the piston rod is connected with lifting plate 314, and lifting plate 314 is connected with lifting rod 313 to...

Abstract

The invention discloses a screen frame overprinting mechanical scrape-printing method. A squeegee which moves in a reciprocating mode is arranged on a work table. In printing, the squeegee scrapes ink, and then ink reclaiming is completed through the same squeegee. An ascending action is conducted to complete ink scraping or ink reclaiming, and then a descending action is conducted to complete ink reclaiming or ink scraping. The squeegee can be a fixed squeegee or a squeegee with an adjustable angle. The squeegee has the advantages of being reasonable in structure, good in scrape-printing effect and the like.

Description

technical field [0001] The invention discloses a screen frame overprinting mechanical scraping method and a scraper, belonging to the technical field of screen frame overprinting according to the International Patent Classification (IPC). Background technique [0002] At present, the mechanized screen frame overprinting adopts a scraper assembly, which is composed of a scraper and an ink return knife (two scrapers), and the two are set at a certain angle. Scrape the ink with a scraper, and then return the ink through the ink return knife. The scraper assembly moves horizontally on the worktable. The scraping or ink return is switched by the rise or fall of the two scrapers. There are many components in the scraper assembly, and the installation requires coordination. , electromechanical control complex. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a mechanical scraping method for screen frame overprinting, ...
