Description

Technical Field

[0001] The present invention relates to the technical field of plastic welding, in particular to a PPH purification tank compartment automatic welding machine and a welding process thereof. Background Art

[0002] The molding process of PPH storage tanks mainly includes the steps of winding molding, welding and pipe nozzle installation, which is characterized by high efficiency, durability and flexibility. The winding molding process of PPH storage tanks uses hot-melt polypropylene granules as raw materials. After being heated and shaped by the extruder, these granules are evenly wound on the steel mold to form the basic shape of the purification tank body. Welding is a key step in the molding of PPH storage tanks, which is divided into external welding and internal welding. External welding uses imported automatic extrusion welding units to hot-melt new PPH granular materials at large welds to ensure the strength and corrosion resistance of the welds. Internal welding uses automatic long-arm extrusion welding technology, which is the welding process of this application. It focuses on the integrity and beauty of the welds, ensuring that the welds are tightly combined with the substrate to form a solid anti-corrosion barrier.

The climbing welding system 2 is used to preheat the purification tank body 5. The direction of the preheating system 3 is parallel to the direction of the climbing welding system 2. The injection width adjustment device 4 is installed at the end of the climbing welding system 2. The injection width adjustment device 4 includes two opening and closing plates 41, a silicone tube 42 and a traction rope 43. The two opening and closing plates 41 are rotatably installed on the climbing welding system 2. The two ends of the traction rope 43 are respectively installed on the opening and closing plates 41 and the climbing welding system 2. The traction rope 43 is transmission-connected with the opening and closing plates 41. The silicone tube 42 is sleeved on the two opening and closing plates 41. The traction rope 43 controls the opening of the opening and closing plates 41, and then controls the width of the molten material extruded by the silicone tube 42.

This is not only convenient for adapting to the welding of purification tanks 5 of different diameters, but also can adapt to the gradual thickening of each solder during welding. The welding extrusion motor 21 is connected to the welding extrusion screw by transmission, and the two opening and closing plates 41 are rotatably installed on the welding extrusion barrel 22 through a pin shaft.

The climbing welding system 2 is mounted on the climbing cage 252. The climbing motor 253 drives the climbing wheel 255 to roll along the top of the climbing rail 251 to change the height of the climbing welding system 2 and adjust the welding position. This is not only convenient for adapting to the welding of purification tanks 5 of different diameters, but also can adapt to the gradual thickening of each solder during welding.

[0045] Specifically, the preheating system 3 is a gas preheating system 3, which preheats the welding position in the purification tank 5. This is a prior art and will not be described in detail here.
