VACUUM PACKING MACHINE WITH A PRESS SWITCH FOR SEALING A VACUUM PLASTIC BAG BY HEATING IN THE OPTIMAL TIME

摘要

PURPOSE: A vacuum packing machine with a press switch is provided to seal a vacuum plastic bag by heating in the optimal time without a vacuum pressure detecting sensor by arranging a simple press switch.;CONSTITUTION: A vacuum packing machine comprises a lower case(110), an upper case(120), a lower packing(130), a vacuum pump, a heating bar, an upper packing(140), a press packing, a press switch(181), and a press protrusion(170). The press switch is installed on an inner substrate of the lower case to start the operation of the heating bar. The press protrusion is installed at a position of the upper case corresponding to the press switch. If the lower packing and the upper packing are pressed over a predetermined level while a seal space is vacuum-pressed by the vacuum pump, the press protrusion presses the press switch.;COPYRIGHT KIPO 2013
