Description
Technical Field
[0001] The utility model relates to the technical field of ton bags and equipment, and more specifically, to a vacuum heat sealing device for a ton bag machine. Background Art
[0002] In the prior art, sealing and storing a loaded ton bag is a relatively common technical means. Generally, the opening of the ton bag is inserted into a heat sealer, the opening part of the ton bag is heated and melted, and the openings of the ton bag are pressed against each other so that the melted ton bags are fused together to finally form a heat seal. Such a sealing process is simple and fast and does not require additional adhesives. However, in the existing heat sealing device during the heat sealing process, powder is likely to escape from the bag mouth of the ton bag, causing dust to adhere to the outer surface of the ton bag. At the same time, during the heat sealing process, since the heat sealing strip is heated to a high temperature and deforms, it is easy to cause problems such as snake-shaped sealing lines and breakpoints at the bag mouth of the ton bag during the heat sealing process. For this reason, we propose a new vacuum heat sealing device for a ton bag machine. Summary of the Utility Model
