Electric fine adjustment system for screen frame of printing machine and printing machine

Abstract

The invention relates to an electric fine adjustment system for a screen frame of a printing machine and the printing machine. The electric fine adjustment system for the screen frame of the printingmachine comprises a printing head beam base, a printing head beam, at least two fine adjustment devices and a control device, wherein one end of the printing head beam is fixed on the printing head beam base; the two fine adjustment devices are symmetrically arranged at two ends of the printing head beam; each fine adjustment device comprises a screen frame cross beam, a fine adjustment frame, anX-axis moving group, a Y-axis moving group and a Z-axis moving group; and the screen frame is limited and fixed between the screen frame cross beams of the two fine adjustment devices. Through the arrangement of the X-axis moving group, the Y-axis moving group and the Z-axis moving group in each fine adjustment device, the screen frame can be adjusted in three directions, and the position of the screen frame can be accurately adjusted, so that printed pattern positions of different printed matters can be accurately aligned, and the influence on the printing effect due to the fact that the position of the screen frame is not easy to adjust in repeated squeegee printing is avoided.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to an electric fine-tuning system for a screen frame of a printing machine and a printing machine. Background technique [0002] The printing machine is a kind of automatic printing equipment, which is suitable for all kinds of printing materials, glue, water slurry, ink, etc., and is suitable for flat screen printing of clothing pieces, ready-made garments, pants, socks, umbrellas, etc.; it is suitable for The advanced printing processes include: thick board, discharge dyeing, and hot stamping and silver hot stamping with a pressing machine. [0003] During printing, the scraper needs to move back and forth to scrape the screen frame so that the dye on the screen frame falls onto the printed matter on the elastic platen. With the lifting and lowering of the print head beam during the printing process, the repeated movement of the scraper and the screen frame Lifting and ...

Problems solved by technology

It is inconvenient to manually rotate the screw rod. At the same time, a printing machine is often equipped with multiple printing devices. Manually rotating and fine-tuning the screen frames one by one requires a lot of work and affects production efficiency; The screw rotates, because it can only set the number of rotations of the screw, and the stepper motor loses steps or stops in place due to the lack of phase during the working process, so it is impossible to know the actual rotation of the screw. The number of moving circles, and the specific position of the slider cannot be clearly known after the reciprocating rotation of the screw rod, so that it needs to be reset every time the product is replaced, which affects production efficiency
