PP hot melt film welding equipment

The utility model discloses PP hot melt film welding equipment, and relates to the technical field of PP film welding equipment for welding and fixing PP sheets on PP films. The PP hot melt film welding equipment overcomes the technical defects that the effect is low, the labor cost is high and the quality is poor in an existing process of welding and fixing a PP sheet to a PP film through ultrasonic welding. The welding device comprises a base, a positioning disc front-back moving mechanism is arranged on the base, a positioning disc is arranged on the positioning disc front-back moving mechanism, a PP film positioning groove is formed in the positioning disc, a PP sheet positioning groove is formed in the PP film positioning groove, and two lower welding heads correspond to two hot melting station holes in position. The two upper welding heads are located above the positioning disc and correspond to the two lower welding heads in a one-to-one mode. The two lower fusion joints and thetwo upper fusion joints
