Heating sealing device and sealing method of special packing machine for sanitary towel products

Abstract

The invention discloses a heating sealing device of a special packing machine for sanitary towel products. The device comprises a supporting plate, a guide rail, an upper sealing plate, a lower sealing plate, upper heating wires and lower heating wires, wherein upper heating wire tensioning structures are arranged at two ends of the upper sealing plate, and lower heating wire tensioning structuresare arranged at two ends of the lower sealing plate; and each upper heating wire tensioning structure comprises an upper left limiting shaft, an upper left compression spring, an upper left locking screw, an upper left copper electrode seat, an upper right limiting shaft, an upper right compression spring, an upper right locking screw and an upper right copper electrode seat, while each lower heating wire tensioning structure comprises a lower left limiting shaft, a lower left compression spring, a lower left locking screw, a lower left copper electrode seat, a lower right limiting shaft anda lower right compression spring, a lower right locking screw and a lower right copper electrode seat. According to the heating sealing device and the sealing method of the special packing machine forthe sanitary towel products, the upper heating wires and the lower heating wires are tensioned at any time, so that the heating wires are prevented from shifting, when the compression springs pull the heating wires, the heating wires are always tensioned in a linear direction, the sealing dislocation caused by the dislocation of the upper heating wires and the lower heating wires is avoided, anda sealing is firm, tidy and attractive.

Description

technical field [0001] The invention relates to parts of a tucking machine dedicated to sanitary napkin products, in particular to a heating sealing device and a sealing method of a tucking machine dedicated to sanitary napkin products. Background technique [0002] The special packaging machine for sanitary napkin products is a special equipment for sorting, stacking and packaging paper sanitary products (such as diapers, paper diapers, sanitary napkins, etc.); The sealing mechanism is the heating and sealing device of the existing tundish machine for sanitary napkin products. The heating wire will expand first after being heated by electricity, and the length is different from that in the cold state (there is also a difference when the temperature is different), which may easily lead to upper and lower electric heating. The length of the wires is inconsistent, which makes the upper and lower heating wires shift, which cannot ensure that the seal is neat and beautiful, whic...
