Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a screen printing machine with an automatic inking function. Background Art

[0002] A screen printer is a machine that uses a screen printing plate to print, and is a type of printing machine. A screen printer is a machine that prints text and images, and is a general term for machines or equipment used to produce printed products. A Chinese utility model patent, with the authorization announcement number "CN218558265U", discloses a screen printer with an automatic inking function, including a bottom plate, the top outer surface of the placement plate is fixedly connected to a lower ink tank, the inner surface of the lower ink tank is fixedly connected to an ink storage tank, and the top outer surface of the floating plate is fixedly connected to a blocking block. In the screen printer with an automatic inking function, the height of the floating plate decreases as the amount of ink decreases. When the floating plate descends, the blocking block is detached from the bottom of the ink storage tank, so that the ink inside the ink storage tank enters the lower ink tank, achieving the effect of automatic inking, and solving the problem that the existing screen printer does not have an automatic inking function, and needs to manually pour and add ink, and needs to use tools to add ink every time, which wastes processing time and reduces printing efficiency.

[0003] The above technical solution places the substrate to be printed on the bottom plate, then puts down the screen plate, and adjusts the position of the scraper and the lower ink brush according to the position where the substrate needs to be printed. The movable frame is pushed to the front end of the substrate by the hydraulic rod, and then the electric push rod drives the first connecting frame downward. Under the action of the telescopic rod, the second connecting frame also moves downward, thereby moving the scraper and the lower ink brush to a position that fits the screen plate, thereby achieving the purpose of being able to adjust the position of the scraper according to the different printing positions of the carrier, improving the printing effect, and increasing the practicality of the printing press. However, the above technical solution still has certain defects. For example, the above equipment moves the position of the scraper and the lower ink brush to a position that fits the screen plate, thereby achieving the purpose of being able to adjust the position of the scraper according to the different printing positions of the carrier. However, the scraper needs to be disassembled and cleaned regularly after long-term use, and the staff needs to carry special tools to disassemble it, which greatly increases the workload of the staff and reduces the disassembly efficiency of the scraper.
