Description

Technical Field

[0001] The utility model relates to the technical field of heat sealing, in particular to a heat sealing device for woven bags. Background Art

[0002] A woven bag heat sealer is a device commonly used in woven bag production. It uses high temperature and pressure to heat-seal the edges or other parts of a woven bag, achieving a seal. This device is commonly used in industries such as plastics and textiles, and plays a particularly important role in the woven bag production process. The operating principle of a woven bag heat sealer is to use high temperature and pressure to melt and bond specific parts of the woven bag. Specifically, the woven bag material softens and melts under the influence of high temperature, and then the pressure tightly bonds it together, forming a strong seal or connection.

Most of the woven bag heat sealing devices in the existing technology are not equipped with an automatic cleaning mechanism for the woven bags. During the heat sealing operation, the dust on the woven bags will affect the bonding strength of the heat seal, resulting in a decrease in the quality of the heat seal and reducing the practicality of the device.
