Heat melting butt joint welder for plastic pipe

Abstract

The present invention relates to heat melting butt jointing welder for plastic pipe and belongs to the field of plastic pipe welding apparatus making technology. The heat melting butt jointing welder includes mainly frame comprising upper frame with controller, lower frame, etc.; clamping mechanism comprising fixed clamps, movable clamps, etc.; cutting mechanism comprising sliding track with turning cylinder, sliding seat with translation cylinder, cutting motor with reducing box, cutting board with lathe tool, etc.; and heating mechanism comprising upper sliding seat, lower sliding seat, heating board sliding body, heating board holder with heating board, etc. The present invention has reasonable design and compact integral structure, and may be used in completing clamping, cutting, heating and butt jointing of different kinds of plastic pipes, especially plastic pipes of caliber as great as 800-2000 mm.

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 there...

[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 at present, the maximum diameter of welded plastic pipes can only be 800mm

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 there is no good method for non-destructive testing of joint quality at present. Therefore, automation of the welding process, real-time monitoring of process parameters and stability of welding quality have become particularly important. However, due to the existing small-scale plastic The welding process of the pipe hot-melt butt welding machine is all manually controlled, and the parameters such as heating plate temperature and welding pressure are not controlled accurately, resulting in poor welding quality and stability
