[0002] Printing inkjet equipment can print on paper, etc., and the printing inkjet equipment is equipped with a suction pipe, which can effectively absorb and remove abrasive solids such as dust, powder, fiber, debris and particulate matter generated during the printing process, keep the working environment clean, and avoid the impact of these particles on printing quality. The suction pipe is connected to the printing inkjet equipment through an adapter, which is convenient for installation or disassembly of the suction pipe.

[0003] In the existing technology, conventional adapters on the market have large rotational resistance and are not smooth. During the back-and-forth movement, the suction tube is easily damaged and ruptured over time, thereby affecting the vacuum adsorption effect. Secondly, the existing conventional vacuum blower is configured as one blower for each workbench to achieve independent control of the workbench, which is costly and generates a lot of heat. The internal temperature of the equipment is high, affecting the printing effect. For this reason, we propose a swing joint vacuum pumping device. Utility Model Content
