[0002] In the process of bread packaging, the bread needs to be put into bags and then sealed, so a bread packaging and sealing machine is needed. In order to improve the sealing efficiency, a conveyor belt is usually installed on the bread packaging and sealing machine to convey the bread packaging for sealing. However, the conveyor belt on the traditional bread packaging and sealing machine lacks a component that can limit the bread packaging bag. Therefore, during the transportation process, the packaging bag is prone to offset or fall on the conveyor belt, thereby affecting the sealing process of the bread packaging bag. For this reason, we propose a bread packaging and sealing machine. Utility Model Content
