[0002] With the development of industry and advancements in processing technology, many manufacturers, especially chemical plants, are producing increasingly fine powder materials, even reaching the nanometer level. These ultrafine powders have a very low density and contain a large amount of air. Consequently, traditional powder packaging machines are unable to process these ultrafine powders, resulting in problems such as poor discharge, incomplete filling, and excessive dust. The emergence of negative pressure packaging machines has easily addressed these issues. They perform quantitative packaging under negative pressure, ensuring effective degassing and resulting in a superior appearance for the finished bags.

[0003] The negative pressure chamber components of the existing negative pressure packaging machine are driven to open and close by an electric slide rail. When packaging powder materials, the electric slide rail is easily damaged by dust. The dust on the electric slide rail needs to be cleaned in time, which is time-consuming and labor-intensive. Therefore, a split-type negative pressure packaging machine is needed to solve this problem. Utility Model Content
