Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing plate cleaning, and particularly relates to a screen printing cleaning device for vehicle glass covers. Background Art

[0002] Screen printing on vehicle glass covers is a process of printing patterns on automotive glass covers, usually used for decoration or functional identification. During the screen printing process, the ink is transferred to the glass surface through a fine wire mesh to form the desired pattern. Since there may be ink overflow or uneven printing during the printing process, after the screen printing is completed, a cleaning step is required to remove excess ink and stains to ensure that the surface of the glass cover is clean and clear. The cleaning step usually includes pre-washing, high-pressure water jet cleaning, ultrasonic cleaning, roller brush cleaning, and final spray rinsing to ensure the perfect presentation of the screen printing pattern and the overall aesthetics of the glass cover.

[0036] Specifically, as Figures 2 - 3 shown, there are two partition plates inside the housing 6, and the two cleaning brush mechanisms 7 are respectively arranged on the opposite sides of the two partition plates. The inside of the housing 6 is divided into three areas by the two partition plates, and the driving device 8 is installed in the middle area. By setting the housing 6, isolation is added between each section of the cleaning machine, and the cleaning between different types of defects does not interfere with each other; the driving device 8 includes a fixing plate 81, the fixing plate 81 is connected inside the housing 6, a hydraulic cylinder 82 is connected under the fixing plate 81, the output end of the hydraulic cylinder 82 is connected with a pull rod 83, a frame body 84 is connected under the pull rod 83, and several rollers 85 are rotatably connected inside the frame body 84.
