Abstract

This application relates to a vertical small bag packaging machine for preventing bag swelling, belonging to the field of packaging machines. It includes a vertical small bag packaging machine body, with a feeding funnel at one end of the machine body. Flow pipes are installed at both ends above the feeding funnel, with a fan installed at one end of each flow pipe. A hollow circular filter screen is installed in the cavity of the feeding funnel. A moving component is located below the machine body. The feeding funnel and the hollow circular filter screen are connected by a disassembly and assembly component. This component allows for easy disassembly and assembly of the filter screen for cleaning or replacement. The structure is convenient to use, allowing for quick disassembly and assembly of the hollow circular filter screen without the need for external tools. The moving component facilitates easy movement of the device, and after movement, the casters can be easily retracted for positioning. Rubber anti-slip pads facilitate the use of friction between the device and the ground.
