Technical Field
[0001] The utility model relates to the technical field of screen printing, in particular to a printing head angle and position adjustment mechanism. Background Art
[0002] The print head is the main component of a printing machine, especially a screen printing machine. A printing scraper is installed on the print head, and the print head also serves as a scraper mounting frame. The scraper moves back and forth on the screen to scrape the printing ink and print the printing ink onto the product, such as on a ceramic film. The positions of different ceramic films on the printing platform may be inconsistent. In order to print in the correct position, the position of the print head and the angle in the horizontal plane need to be adjusted. At present, the front, back, left, and right accuracy of the print head still rely on processing benchmarks and manual correction adjustment in the XY direction. This process leads to difficult processing, inaccurate manual adjustment, time-consuming and labor-intensive, poor operating stability, and the inability to make timely adjustments to ceramic films with different deflections.
