[0002] The thin film valve inflatable bag heat sealing machine is specially designed for the heat sealing operation of the thin film valve inflatable bag, generates heat through the electric heating element, and realizes the heat fusion of the thin film material. The heat sealing machine has the temperature regulation capability, and the operator can accurately regulate the heat sealing temperature within a certain range according to the thin film material quality, thickness and heat sealing process requirements. The heat sealing machine is widely used in the inflatable bag packaging production of the food, medicine and chemical industries, and ensures the sealing performance and reliability of the packaging.

In the heat sealing process, the two parts are prone to relative displacement due to thermal stress or mechanical vibration. Such displacement seriously interferes with the accuracy of heat sealing, eventually leads to poor sealing performance of the heat sealing part, gas leakage, and greatly affects the product quality and use safety. In order to improve the above-mentioned defects, the present application provides a thin film valve inflatable bag heat sealing machine with adjustable heat sealing temperature. SUMMARY

[0007] Preferably, the elastic mechanism comprises a spring sleeved outside the positioning frame rod part, and the spring is connected with the outer wall of the positioning frame head part and the outer wall of the movable frame at two ends respectively.

[0008] Preferably, the rotating mechanism comprises a gear mounted on the output shaft of the rotating motor, and a rack engaged with the gear is arranged on the rotating frame.

[0012] The beneficial effects of this utility model are:

[0013] 1. The spring design in the elastic mechanism ensures that the positioning frame first contacts the opening of the inflatable bag, guaranteeing a tight fit between the bag opening and the valve body. Subsequently, the movable frame further reinforces the design, significantly improving the stability of the contact between the bag opening and the valve body during heat sealing and enhancing the heat sealing quality.

[0014] 2. The rotary motor, combined with the gear and rack rotation mechanism, allows the heating component to rotate around the valve body, achieving a full-range and continuous heat sealing operation. Compared with traditional heat sealing methods, the heat sealing efficiency is significantly improved, and the heat sealing is more uniform.

[0015] 3. The L-shaped design of the movable slot and the rotating frame, as well as the ingenious setting of the friction between the rotating frame and the movable slot, allows the rotating frame to be easily detached from the movable slot after heat sealing, facilitating daily maintenance, inspection or replacement of the heating components, and reducing maintenance costs and time.
