[0003] During use, the automatic hot-melt welding device for plastic pipe end fittings in this patent application uses a telescopic cylinder to complete the matching of the pipe fitting and the hot-melt seat, and then pushes the hot-melt seat through the telescopic cylinder again to complete the matching of the hot-melt seat and the pipe, thereby realizing simultaneous hot-melting of the pipe fitting and the pipe. However, during such use, the telescopic cylinder needs to overcome the elastic force of the return spring when pushing the hot-melt seat through the pipe fitting, so that the return spring will form a large reaction force on the pipe fitting through the hot-melt seat, which can easily cause serious deformation of the pipe fitting during the hot-melt process, affecting the welding quality between the pipe fitting and the pipe. For this reason, we propose an automatic hot-melt welding device for plastic pipe end fittings. Utility Model Content
