[0002] Plastic pipes are chemical building materials made of high-tech composites. Chemical building materials are the fourth largest category of new building materials after steel, wood and cement. Plastic pipes are widely used in building water supply and drainage, urban water supply and drainage, and gas pipes due to their advantages of small water flow loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban construction pipe networks in the new century. Plastics are different from traditional materials. The pace of technological progress is faster. The continuous emergence of new technologies, new materials, and new processes has made the advantages of plastic pipes more and more prominent compared to traditional materials.

[0003] Existing plastic pipes are mostly butt-jointed by manual devices during hot-melt butt-jointing. This method is not only time-consuming and labor-intensive, reducing the efficiency of hot-melt butt-jointing of plastic pipes, but also has a large precision error, affecting the normal use of subsequent plastic pipes.

[0004] Therefore, we propose a plastic pipe hot-melt butt-jointing mechanism. Utility Model Content
