[0002] A vertical packaging machine is a device used for material packaging. The processed materials are packaged according to weight through the vertical packaging machine to improve the efficiency of industrial production packaging. The machine base is one of the accessories of the vertical packaging machine, and the machine base is used to support and fix the vertical packaging machine.

[0003] The base of the traditional vertical packaging machine is a fixed structure. When the packaging machine is installed on the base by screws, the height and position of the packaging machine are fixed and the height cannot be adjusted according to demand. Since the height of material unloading is constant, it is easy to cause a large gap between the material unloading position and the packaging machine's receiving position, which increases the impact problem of material unloading. For this reason, we designed an adjustable base for the vertical packaging machine. Utility Model Content
