Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a sealing device suitable for a bagging machine. Background Art

[0002] A bagging machine is a machine that uses prefabricated packaging bags to package materials. It is a packaging machine that puts bags on materials or puts materials into bags. During the product packaging process, the sealing quality and efficiency of the bagging machine directly affect the packaging effect and production efficiency of the product. However, the existing bagging machine sealing device cannot perform continuous and coherent sealing, and cannot complete the sealing of a large number of bags in a short time. It is also inconvenient to replace and maintain the heat sealing knife, which may lead to problems such as loose and uneven sealing due to aging or damage of the heat sealing knife, causing many problems in production. Therefore, we propose a sealing device suitable for bagging machines to solve this problem. Utility Model Content
