Hot welding mechanism for pull-ups

Abstract

The invention relates to the field of hygienic product equipment, in particular to a hot welding mechanism for pull-ups. The hot welding mechanism comprises a rack, a first welding roller and a second welding roller. Two heat conduction copper plates are arranged at the position, close to the edge, in the first welding roller, the distance between the heat conduction copper plates and the first welding roller is 3-5 cm, extending parts are arranged at the upper ends and the lower ends of the heat conduction copper plates, the extending parts surround halves of the peripheries of first mounting holes, and the extending parts and heating pipes are arranged at intervals. Due to the fact that the extending parts at the head ends and the tail ends of the heat conduction copper plates surround the heating pipes and meanwhile the extending parts extend into welding blocks, heat can be conducted to the surface of the middle of the first welding roller in the using process, heat dissipation holes are formed in the position,close to the heat conduction copper plates, of the first welding roller at intervals, heat of the part, close to the heat conduction copper plates, of the first welding roller can be taken away more quickly, and therefore heat dissipation of the welding blocks is accelerated through the first welding roller, and the problem that the heating temperature of the parts, close electric heating pipes, of the welding rollers is not prone to being reduced is solved.
