Claims

[Claims for Utility Model Registration] (1) A roller for supplying and pulling back a band made of a heat-fusible material, a means for gripping the tip and supply end of the band that is wrapped around the object to be packed, and the tip side of the band. In a packaging machine equipped with a camshaft that operates a band melting means that has a heating plate that can move forward and backward between the overlapping surfaces of the heating plate and the supply end side, the heating plate has a thin plate shape that is connected at both ends to a current-carrying lead wire, respectively. It is composed of an electric heating resistor, an insulating plate that clamps the electric heating resistor in a sheath, and a metal body that holds and secures the insulating plate in a sheath, and the heating plate is heated within an appropriate temperature range for band welding. a first connection circuit that supplies a constant power to heat the heating plate within the band welding allowable temperature range; a second connection circuit that supplies a constant power higher than the constant power that heats the heating plate to within a band welding allowable temperature range; switch means for switching the first or second connection circuit to the heating plate, at least during the operation of the band melting means by the rotation of the camshaft from the start of the rotation of the camshaft until the end of band supply after the rotation of the camshaft is stopped; A band melting device for a packaging machine, characterized in that the second connection circuit is connected to the band melting device. (2) The band melting device for a packaging machine according to claim 1, wherein the electric heating resistor is made of a nichrome plate, and the nichrome plate is formed into a substantially M-shape. (3) The package according to claim 1, wherein the metal body is made of a stainless steel tube, a mica plate with an electric heating resistor sandwiched therein is housed in the stainless steel tube, and the stainless steel tube is flattened. band melting equipment in the machine. (4) The power of the first connection circuit is 3.2V×8
A, and the power of the second connection circuit is 4V×1
A band melting device for a packaging machine according to claim 1 of the utility model registration claim 1A. (5) The utility model registered in claim 1, wherein the heating plate is energized via a second connection circuit only when the heating plate is melting the band inserted into the band overlapping part by rotation of the camshaft. Band melting device in packaging machine.
