Working hour, the size of the distance moved in heat seal seat using heat-fastening knife are linked into the first magnet exciting coil time to change slide rheostat
Resistance size in road, so that the first magnet exciting coil obtains different size of electric current, what the first magnet exciting coil obtained
Size of current is different so that pedestal will generate cutter hub different size of active force, finally so that cutter hub band dynamic cutter head is to heat-sealing
The polybag at place generates different heat-sealing pressure, therefore this programme automatically can adjust knife according to the thickness of the polybag of processing
Head does not need to be adjusted by way of artificially replacing compression spring to the heat-sealing pressure of polybag, effectively raises pair
The processing efficiency of polybag reduces the labor intensity of worker.
3rd, this programme applies the polybag at heat-sealing heat-sealing pressure using the magnetic force that pedestal generates cutter hub to realize
Purpose, with traditional compared with compression spring is provided by the way of heat-sealing pressure, the working performance more stabilization of this programme can
