Abstract

This invention discloses a ton bag sealing device and heat sealing method, belonging to the field of ton bag packaging technology. It aims to solve the problems of insecure heat sealing, bag opening damage, and uneven heat sealing caused by fluctuations in the negative pressure environment during the existing ton bag heat sealing process, which lead to a mismatch between heat sealing parameters and negative pressure. The invention improves the stability and reliability of ton bag heat sealing quality. The ton bag sealing device of this invention includes a sealing box, a clamping and conveying mechanism, a heating mechanism, a vacuum pump, and a control system. The heat sealing method is based on a negative pressure-coordinated constant temperature heat sealing method. During the heat sealing process, the negative pressure value inside the sealing box and the temperature of the heating mechanism are monitored in real time. When the negative pressure fluctuates, the temperature of the heating mechanism and the heat sealing time are adjusted synchronously to achieve dynamic coordination and matching between negative pressure and heat sealing parameters.
