AI Technical Summary
Existing swing arm screen printing machines have poor versatility when printing on both large and small areas. Large-area swing arm screen printing machines are expensive and have poor safety, while small swing arm screen printing machines are difficult to expand to larger areas, resulting in insufficient equipment versatility and safety.
A dragon-shaped rocker arm screen printing machine with easy horizontal adjustment was designed. Through the modular design of the receiving body components, including wing plates, screen arm connecting components and squeegee arm preset interface, combined with pneumatic or electric drive mechanism, the machine achieves precise opening and closing control of squeegee arm and screen arm and flexible adjustment of adjustable lifting worktable to adapt to printing needs of different areas.
It improves the equipment's versatility and safety, reduces expansion costs, enhances loading and unloading efficiency and printing quality, simplifies the machine setup process, and solves the problems of labor shortages and recruitment difficulties.
