However, when sealing the negative pressure cleaning tank, the staff needs to install and fix the sealing cover, and the sealing cover still needs to be removed when unloading the material. This results in a lot of time being spent loading and unloading the workpieces, which reduces the cleaning efficiency of the workpieces. Utility Model Content
