Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of silk screen printing, and relates to a silk screen printing device, in particular to a device capable of silk screen printing on the cylindrical surface of a columnar object. BACKGROUND

[0002] ‌Silk screen printing is a printing technology that uses silk screen as a plate base, makes a silk screen printing plate with graphics by a photosensitive plate making method, tightly attaches the graphic position of the silk screen printing plate to a to-be-printed object, uniformly scrapes the ink scattered on the silk screen printing plate over the graphic position through a squeegee, and prints the ink on the surface of the to-be-printed object through the holes of the graphic position to form a corresponding pattern.

[0003] At present, when silk printing is performed on the cylindrical surface of a to-be-printed object, a silk screen printing plate that matches the curvature of the cylindrical surface of the to-be-printed object is usually made to perform silk printing, so as to ensure that the graphic position can be well attached to the to-be-printed object and avoid the phenomenon of incomplete printing pattern, uneven pattern color, or shadow ink due to poor attachment.

[0004] When silk screen printing is performed by using an arc-shaped screen plate, manual operation of the squeegee is required to work on the arc-shaped silk screen printing plate, and it is difficult to ensure the stability of the squeegee when it is scraped on the silk screen printing plate, so that the speed and pressure of the squeegee when it is scraped over the graphic position cannot be ensured to be always consistent. The speed and pressure of the squeegee will both affect the ink leakage amount of the graphic position of the silk screen printing plate. If the speed and pressure of the squeegee change greatly during the process of the squeegee passing through the graphic position, the final printing effect will be affected, and re-erasing and rework are required, which affects the production efficiency.
