A screen printing device with uniform ink distribution for batch processing

Abstract

The invention provides silk screen printing equipment suitable for batch processing and realizing even ink distribution. The silk screen printing equipment comprises a bottom plate, a silk screen fixing mechanism, an ink spraying mechanism and pneumatic guide rails, wherein the silk screen fixing mechanism is fixedly installed on the bottom plate; the ink spraying mechanism comprises a sliding platform, an ink scraping plate, a connecting plate, linear bearings, a reset spring, an ejector rod, a cam and a motor; the sliding platform is installed on the pneumatic guide rails, the ink scraping plate is movably installed at the bottom of the sliding platform, one end of the connecting plate is fixedly connected with the ink scraping plate, and the other end of the connecting plate is installed on the linear bearings; and the connecting plate is sleeved with the reset spring, the ejector rod is installed on the connecting plate through bolts, the motor is mounted on the sliding platform, the power output end of the motor is fixedly sleeved with the cam, and the cam makes contact with the ejector rod. The ink scraping plate is pushed by the cam to reciprocate, the ink scraping plate canmove on a silk screen during ink scraping so that the ink can be evenly sprayed to printing materials, the ink scraping plate can move through clamping plates in the silk screen fixing mechanism, andthe silk screen is replaced more conveniently.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a screen printing equipment suitable for batch processing with uniform ink distribution. Background technique [0002] In screen printing, it mainly uses the basic principle that the graphic part of the screen printing plate is ink-permeable, and the non-graphic part of the mesh is impervious to ink. When printing, ink is poured into one end of the screen printing plate. Use the scraper to apply a certain pressure on the ink part of the screen printing plate, and at the same time move towards the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh of the graphic part to the substrate by the scraper. [0003] Publication No. CN107031171A provides a screen printing device with an inking mechanism. This device performs screen printing by moving the scraper back and forth. When printing, the scraper only scrapes the paint to the m...

[0003] Publication No. CN107031171A provides a screen printing device with an inking mechanism. This device performs screen printing by moving the scraper back and forth. When printing, the scraper only scrapes the coating to the mesh of the screen and cannot guarantee ink. Whether it leaks out from the mesh evenly, and the screen is fixedly installed on the frame, it is inconvenient to replace the screen of different shapes
