Description

Technical Field

[0001] The utility model relates to the technical field of food processing and production, and particularly relates to an automatic filling and sealing machine. Background Art

[0002] In the process of producing bowl-shaped or cup-shaped turtle jelly, a filling and sealing device is required. The filling and sealing device is an automatic device that places a packaging container on the hole of a container template, and drives the packaging container to a filling port for material filling under the drive of the container template, and then seals a sealing film to the cup mouth or bowl mouth through a sealing part. When the existing filling and sealing device performs filling, sealing and other production processes, since the container template needs to frequently stop and start to drive the packaging container to move, the packaging container is prone to vibration and shaking, resulting in the overflow of the liquid material in the container and polluting the container template. If the overflow liquid on the container template is not removed in time, it is easy to breed bacteria and contaminate food. If the method of regular shutdown for cleaning is adopted, although it can reduce the generation of pollution, it will undoubtedly affect the production efficiency of the whole line. Content of the Utility Model
