Description

Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a static electricity eliminating device for bag making machines. Background Art

[0002] A bag making machine is a machine that makes various plastic packaging bags or other material packaging bags. Its processing range is plastic or other material packaging bags of various sizes, thicknesses and specifications. With the development of society, the number of packaging bags used is gradually increasing. Therefore, at present, many bag making machines can prepare multiple packaging bags at the same time, thereby ensuring that the supply of packaging bags is sufficient. When the bag making machine is producing packaging bags, in order to avoid uneven cutting due to static electricity adsorption between multiple packaging bags, an electrostatic rod is often set to remove static electricity on the packaging bags to ensure normal and stable production.

[0003] After searching, it was found that the authorized patent with announcement number CN 218416756 U in the prior art discloses a static electricity removal device for a bag making machine based on intelligent control, including a workbench and a support frame fixed on both sides of the top surface of the workbench in an inverted U-shaped structure, a driving rod is rotatably inserted at the center position of the support frame, and a mounting frame is protruding from the top of the support frame, wherein a lifting plate connected to the driving rod is slidably provided at the bottom end of the support frame, and the two driving rods rotate synchronously through an engaging assembly, and a motor connected to the driving rod is fixed to the top of the mounting frame, an infrared ranging assembly is fixed to the side wall of the lifting plate, and a supporting bolt is provided on the side wall of the supporting frame, and the supporting bolt passes through the supporting frame and is fixedly connected to the workbench. The static electricity removal device for a bag making machine based on intelligent control is convenient for adjusting the distance between the static electricity removal device and the bag making machine, thereby improving the applicability of the static electricity removal device, and is convenient for adjusting the height of the static electricity removal device, thereby improving the convenience of the static electricity removal device.

[0004] However, when the above technical solution is used, static electricity can only be eliminated on one side of the packaging bag, and the static electricity elimination effect of the packaging bag is poor. In this regard, we propose an static electricity elimination device for a bag making machine. Utility Model Content
