Description

technical field

[0001] The invention relates to a plastic pipe hot-melt butt welding machine, which belongs to the technical field of manufacturing plastic pipe welding equipment. Background technique

[0002] The existing plastic pipe hot-melt butt welding machine has a low degree of automation. The clamping of the plastic pipe, the insertion and removal of the milling cutter and the heating plate must be done manually, and the pipe end cutting adopts a disc milling cutter, which is cumbersome to use. And the maximum diameter of welded plastic pipes can only be 800mm at present. Due to the complexity of the welding process of plastic pipes, whether the three parameters of the process temperature, pressure, and time are accurately controlled during the welding process will directly affect the quality of the welding. Manual control inevitably produces deviations, and the quality of joints welded by different operators It will also be different, and ther...
