The purpose of the present invention is to provide a safety device for a sealing machine which can safely seal the inlet of a waterproof pack (plastic cover) where a cellular phone is stored, without any burn or injury of a user who does not have related skills. The present invention is based on the conventional temporary sealing machine for a waterproof pack, where an operating heater descends, hot-presses the inlet of a waterproof pack placed on a fixated heater, and then returns when pushing the inlet of the waterproof pack where a cellular phone is stored into the inlet of the sealing machine and pressing a switch. However, the safety device for a sealing machine prepared by the present invention can sense a finger which is wrongly placed on the inlet of a sealing machine through a sensor and can reversely operate a step motor in order to immediately lift and restore a descending elevating body, by installing the sensor for transmitting a normal or reverse operation signal of the step motor and by installing a safety pin that is installed in the front side of the elevating body and descends along with the elevating body that descends to hot-press. |
