Automatic feeding and dust preventing device for welding wire of extrusion welding gun for pipeline heat-insulation joint

Abstract

The invention relates to the technical field of heating pipe network construction equipment, and discloses an automatic feeding and dust preventing device for a welding wire of an extrusion welding gun for a pipeline heat-insulation joint. The automatic feeding and dust preventing device comprises a ground-inserting vertical rod device, a ground-inserting bending rod is fixedly welded to the rightside face of the ground-inserting vertical rod device, a supporting rod is fixedly mounted at the top of the ground-inserting vertical rod device, a connecting shaft is fixedly mounted at the top ofthe supporting rod, and a thrust ball bearing is fixedly connected to the exterior of the connecting shaft in a sleeving mode. Through arrangement of a rotating shaft assembly body serving as an assembly body, a maximum diameter value of the rotating shaft assembly body is matched with a plastic welding wire shaft, the stability of the plastic welding wire shaft is improved, the plastic welding wire can be wound around the exterior of the plastic welding wire shaft through the plastic welding wire shaft, the plastic welding wire is convenient to mount, through a servo motor, the unwinding speed of the plastic welding wire is matched with the speed of consumption of the plastic welding wire by the plastic extrusion welding gun, the purpose of automatic feeding is achieved, and the welding speed is high.

Description

technical field [0001] The invention relates to the technical field of heating pipe network construction equipment, in particular to a dust-proof device for automatic feeding of welding torches and wires for pipe insulation joints. Background technique [0002] The heating system is a facility that uses artificial methods to supply heat to the room to maintain a certain temperature in the room to create suitable living conditions or working conditions. It is mainly composed of three main parts: heat source, heat circulation system and heat dissipation equipment. The heat circulation system is In order to make the pipe network have good resistance and heat preservation effect, the heat preservation pipe network spliced ​​by the conveying pipes needs to use plastic extrusion when the prefabricated direct-buried heat preservation pipe is used for heat insulation repair or PE outer protection pipe for pipe fittings. The welding gun heats the plastic welding wire, and after the p...
