Description

Technical Field

[0001] The utility model relates to the field of screen printing, in particular to a composite component used for screen printing. Background Art

[0002] Screen printing is to stretch silk fabric, synthetic fiber fabric or metal screen on the screen frame, and make the screen printing plate by hand-carving paint film or photochemical plate making. Modern screen printing technology uses photosensitive materials to make screen printing plates by photoengraving (making the screen holes of the graphic part of the screen printing plate through holes, and the screen holes of the non-graphic part are blocked) for oil paintings, prints, posters, business cards, binding covers, product packaging, product labels, printed and dyed textiles, glass and metal and other flat carriers.

[0003] In actual production, after the screen is made, multiple processes such as lamination, gluing, and fixing are required. During manual operation, the PI film may be offset, thus affecting the subsequent printing accuracy and printing effect. Utility Model Content

When in use, place the substrate on the base, then insert the screen into the plate holder, fix the PI film on the bottom of the film plate, and then start the cylinder to drive the cylinder spindle to move forward, thereby driving the plate holder to move forward and bring the screen to the designated working position. During the forward movement of the plate holder, the driving connecting rod will be driven forward, thereby driving the slide rail to move, and then driving the lifting plate to move, driving the two lifting plates to move downward at the same time, thereby driving the film plate to move downward until the PI film at the bottom of the film plate fits with the silk screen on the screen. At this time, the glue brushing work can be carried out. When the cylinder spindle moves forward, it will drive the connector to move forward, thereby driving the rack to move forward. When the rack moves forward, it will drive the driving gear to rotate, thereby driving the two driving rods to rotate, and then driving the base to move upward, thereby driving the substrate to move upward, and sending the substrate to the working position. At this time, printing work can be carried out.
