Description

Safety bag manufacturing equipment, manufacturing method and safety bag manufactured using the same {Envelop manufacturing apparatus, method and envelop manufactured by the same}

The present invention relates to a safety bag manufacturing equipment, a manufacturing method, and a safety bag manufactured using the same. More specifically, the ultrasonic and high frequency welding equipment and its method are applied to the manufacturing equipment of the safety bag. It is a processing technology in which thermoplastic resins are melted and bonded instantaneously by minute ultrasonic waves, high frequency vibration, and pressing force.

That is, 50 / 60Hz power is supplied as 15KHz ~ 20KHz (1sec) electric energy through oscillator and converted into mechanical vibration energy through converter and booster. After that, when it is delivered to vinyl, it generates instantaneous frictional heat due to strong vibration, and the bonding surface of vinyl is dissolved and bonded to form molecular bonds. The ultrasonic and high frequency welding facilities as described above and the envelopes produced by the method Air caps can be welded to the front instead of part of the envelope support, which not only ensures superior robustness and merchandise, but also enables mass production by automating the entire production process of safety bags with heat-sensitive air caps. do.
