Screen printing device for tubular workpiece

Abstract

The invention relates to a screen printing device for a tubular workpiece. The screen printing device comprises a base, a driving mechanism, a liquid injection mechanism and a limiting clamping mechanism. According to the screen printing device for the tubular workpiece, reciprocating motion of a moving rod is achieved through the driving mechanism, the liquid injection mechanism is driven by the moving rod to inject printing ink on a screen plate, and the workpiece is clamped through the limiting clamping mechanism. The limiting clamping mechanism is driven by the moving rod to move, and therefore screen printing is conducted on the outer wall of the workpiece. Compared with an existing screen printing device, online supplement of the printing ink and online screen printing of the workpiece are achieved through linkage of the driving mechanism, the liquid injection mechanism and the limiting clamping mechanism, and a pure mechanical structure is adopted for the linkage. Stability of the device is improved, and the service life of the device is prolonged. Compared with an existing liquid injection mechanism, the printing ink is evenly rolled through a roller, the screen printing effect is improved, flexible pressure is adopted, the service life of the screen plate is prolonged, and compared with an existing clamping mechanism, flexible clamping is adopted for the mechanism, and the workpieces is protected.

Description

technical field [0001] The invention relates to a screen printing device for tubular workpieces. Background technique [0002] Screen printing refers to the use of screen as the plate base, and through the photosensitive plate-making method, to make a screen printing plate with graphics. Screen printing is composed of five major elements: screen printing plate, scraper, ink, printing table As well as the 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. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part on the screen printing plate with a scraper, and move towards the other end of the screen printing plate at a constant speed, and the ink is moved by the scraper from the image and text during the movement. Part of the mesh is extruded onto the substrate. [0003] Existing screen printing equ...

Problems solved by technology

[0003] Existing screen printing equipment generally adopts rigid clamping for workpiece clamping, which is easy to scratch the surface of the workpiece and even cause damage to the workpiece. At the same time, the existing screen printing equipment generally requires multiple output terminals for ink addition, workpiece transmission and printing drive, consumes a large amount of energy
