Description

Technical Field

[0001] The present invention relates to the technical field of plastic welding, and particularly to an automatic welding machine for PPH purification tank compartments and its welding process. Background Art

[0002] The forming process of PPH storage tanks mainly includes steps such as winding forming, welding, and nozzle installation, and has the characteristics of high efficiency, durability, and flexibility. The winding forming process of PPH storage tanks uses hot-melt polypropylene particles as raw materials. After being heated and shaped by an extruder, these particles are evenly wound around a steel mold to form the basic shape of the purification tank body. Welding is a key step in the forming of PPH storage tanks, which is divided into external welding and internal welding. External welding uses an imported automatic extrusion welding unit to melt brand-new PPH particle materials at large welds to ensure the strength and corrosion resistance of the welds. Internal welding uses an automatic long-arm extrusion welding process, which is also the welding process of this application, focusing on the integrity and aesthetics of the welds, ensuring that the welds are tightly combined with the base body to form a strong anti-corrosion barrier.

[0003] The existing automatic welding machines have insufficient ability to adjust the welding width, which may result in insufficient strength of the welding firmness. Summary of the Invention

[0024] The present invention will be further described below with reference to the accompanying drawings: As Figure 1 — Figure 7 shown, this embodiment provides an automatic welding machine for the partition bin of a PPH purification tank. The purification tank body 5 forms several partition bins through the partition board 6. The purpose of this automatic welding machine is to weld the partition board 6 to the purification tank body 5. The automatic welding machine includes a tank moving system 1, two tank moving guide rails 12, a climbing welding system 2, a preheating system 3, and an injection width adjustment device 4. The tank moving guide rails 12 are parallel to each other. The tank moving system 1 is slidably installed on the two tank moving guide rails 12. The tank moving system 1 is located on the side of the climbing welding system 2, and thus drives the purification tank body 5 to move towards or away from the climbing welding system 2, thereby controlling the welding position. The sliding direction of the tank moving system 1 points to the climbing welding system 2. The preheating system 3 is installed on the climbing welding system 2 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 barrel 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 in transmission connection with the opening and closing plates 41. The silicone barrel 42 is sleeved on the two opening and closing plates 41. The traction rope 43 controls the opening degree of the opening and closing plates 41, and thus controls the width of the molten material extruded by the silicone barrel 42. After the purification tank body 5 rotates one circle, the extrusion width of the silicone barrel 42 is increased to achieve layer-by-layer welding and ensure the welding strength.

[0025] Specifically, the injection width adjustment device 4 also includes a control cylinder 45, which is installed on the climbing welding system 2. The traction rope 43 is pressed on the output end of the control cylinder 45. The control cylinder 45 pushes the traction rope 43 to change the bending degree, thereby driving the opening and closing plate 41 to open or narrow.

[0026] Specifically, the tank moving system 1 includes two tank moving trolleys 11 , and each tank moving trolley 11 slides along the tank moving guide rail 12 , thereby realizing the movement of each tank moving trolley 11 , and further driving the movement of the purification tank.

[0027] Specifically, each tank moving trolley 11 includes a tank moving frame 111, a tank moving wheel 112 and a tank rotating device 113. The tank rotating device 113 is installed on the tank moving frame 111, and the tank moving wheel 112 is installed at the bottom of the tank moving frame 111. The tank moving wheel 112 rolls along the tank moving guide rail 12, thereby driving the movement of the tank moving trolley 11.

[0028] Specifically, a tank moving frame 111 is further provided with a tank moving motor 115 , and the tank moving motor 115 is transmission-connected with the tank moving wheel 112 , thereby driving the tank moving frame 111 to move.

[0029] Specifically, the tank body rotating device 113 includes a tank body rotating motor 1131 and a tank body rotating wheel 1132. The tank body rotating motor 1131 is installed on the tank body moving frame 111, and the tank body rotating wheel 1132 is rotatably installed on the tank body moving frame 111. The tank body rotating motor 1131 is transmission-connected to the tank body rotating wheel 1132, thereby driving the purification tank body 5 to rotate.

[0030] Specifically, the climbing welding system 2 includes a climbing system 25, a welding extrusion motor 21, a welding extrusion screw, a welding extrusion barrel 22 and a hopper 23. The hopper 23 is installed on the welding extrusion barrel 22, and the welding extrusion screw is rotatably installed in the welding extrusion barrel 22. The welding extrusion barrel 22 is installed on the welding extrusion motor 21, and the welding extrusion motor 21 is installed on the climbing system 25. The side of the climbing system 25 away from the tank moving system 1 is lower than the side close to the tank moving system 1, thereby adjusting the height of the welding extrusion barrel 22 and adjusting the welding position, which 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 driving, and the two opening and closing plates 41 are rotatably installed on the welding extrusion barrel 22 through a pin shaft. The hopper 23 is connected to the welding extrusion barrel 22 to realize the extrusion of molten material.

[0031] The climbing system 25 includes a climbing rail frame 251, a climbing cage frame 252, a climbing motor 253 and a plurality of climbing wheels 255. The climbing rail frame 251 is set between two tank moving guide rails 12. The side of the climbing rail frame 251 close to the tank moving system 1 is lower than the side away from the tank moving system 1. Each climbing wheel 255 is rotatably mounted on the climbing cage frame 252. The climbing motor 253 is mounted on the climbing cage frame 252. The climbing motor 253 and each climbing wheel 255 are connected by a transmission chain or a synchronous belt. Each climbing wheel 255 rolls along the top of the climbing rail frame 251. The climbing welding system 2 is mounted on the climbing cage frame 252. The climbing motor 253 drives the climbing wheel 255 to roll along the top of the climbing rail frame 251, changes the height of the climbing welding system 2, and adjusts the welding position, which 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.

[0032] Specifically, the preheating system 3 is a gas preheating system 3, which preheats the welding position in the purification tank body 5. This is a prior art and will not be described in detail here.

[0033] The automatic welding process of the septic tank compartment uses the PPH septic tank compartment automatic welding machine, including the following steps: S1: placing the purification tank 5 on the tank moving system 1, and the tank moving system 1 drives the purification tank 5 to rotate; S2: The tank moving system 1 drives the purification tank 5 to move and then adjusts the relative position of the climbing welding system 2 and the purification tank 5; S3: Turn on the climbing welding system 2; S4: The injection width adjustment device 4 is expanded after each rotation of the purification tank body 5.
