Table board type silk-screen printing device

Abstract

The invention discloses a table board type silk-screen printing device. The device comprises a printing machine head, a printing table and a screen printing plate positioning mechanism. According to the device, all the components precisely and accurately cooperate, so that the lifting height adjustment, left-right height balance adjustment and front-back pitching posture adjustment of a scraper and an ink return cutter are achieved, adjusting is accurate, locking is firm, and working is stable; an additional box body provides reliable support for a support plane and forms a reliable adsorptionpositioning effect on a printing stock; the height, the left-right position and the front-back position of a screen printing plate are accurately, stably and reliably adjusted; the device is high inintegration degree, compact in overall structure, small in size and precise in cooperation, and the purpose of effectively using a table board is achieved; and meanwhile, all the working mechanisms are conveniently, accurately and reliably connected and locked so that the stable printing precision can be kept all the time, and the printing quality is conveniently and effectively improved.

Description

technical field [0001] The invention relates to a screen printing device. Background technique [0002] Screen printing consists of five major elements, screen printing plate, scraper, ink, printing table and substrate. Use the basic principle that the graphic part of the screen printing plate can pass through the ink, and the non-graphic part of the mesh cannot pass through the ink. [0003] In application scenarios such as the development of new product printing processes, small desktop screen printing equipment is often required to be put into small batch production. However, the existing screen printing equipment is generally large in size. Currently, the screen printing table is suitable for desktop operation. It has a simple structure and low production cost. However, the existing screen printing table has adjustment accuracy during use. Low, inconvenient operation and other issues: for example, the printing table on which the substrate is placed is a simple support ...

Problems solved by technology

However, the existing screen printing equipment is generally large in size. Currently, the screen printing table is suitable for desktop operation. It has a simple structure and low production cost. However, the existing screen printing table has adjustment accuracy during use. Low, inconvenient operation and other issues: for example, the printing table on which the substrate is placed is a simple support plane

However, the adjustment accuracy of this adjustment method is difficult to meet the requirements; at the same time, the force of the ink knife 30 and the scraper 35 may change in attitude during work, and the adjusted working attitude cannot be stably and reliably maintained, and the stable printing accuracy cannot always be maintained.
