Thermally sealing cutter of bag maker

The utility model relates to a thermal sealing cutter, in particular to a thermally sealing cutter of bag maker, which is characterized in that both sides of the thermal cutter are arranged with an electrical heating board, with a conducting ring that is in ca-axis linkage with the rotary axis and is arranged on the exterior side of the other installation base, which is on opposite to the installation base arranged with the manipulation hand wheel. The conducting ring is electrically connected with the electrical heating board. A rotary conducting conjugation comprises the conducting ring and the conducting carbon brush in communication with the power for bag production machine is also arranged at the corresponding site of the installation base. Because the power of the bag production machine is connected with the electrical heating board through the conducting carbon brush and the conducting ring, the latter two even in relative rotation maintain the mutual contact (i.e. the electrical connection) when the thermal cutting knife and the conducting carbon rotate, to prevent the wires from being twisted, and increase working safety and reliability and beautify the appearance.
