A rotating shaft is rotatably connected to the upper end of each opposite side of the two support plates, and a U-shaped worktable is fixed to the opposite end of the two rotating shafts. Through the arrangement of the U-shaped worktable, a first rotary handle, connecting shafts, gears, two racks, a movable seat, and clamping plates, the device achieves the effect of clamping the seat frame, facilitating welding work and improving welding stability. After the first rotary handle rotates, it is limited by a spring, connecting block, limiting rod, and limiting hole, maintaining stability during clamping and further improving the stability of the welding process.

[0004] While the aforementioned structure has achieved certain results in improving clamping stability and welding operation convenience, it still reveals many shortcomings in practical applications. The welding process generates a large amount of welding fumes, and existing equipment lacks an effective fume treatment system, causing fumes to spread throughout the workshop. This not only affects the health of operators but also reduces the comfort of the working environment and fails to meet the increasingly stringent environmental protection and occupational health and safety standards of modern manufacturing. Therefore, there is an urgent need to develop a new type of welding equipment for processing automotive seat frames to solve these problems. Utility Model Content

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 A welding device for processing automotive seat frames includes a base 1, a welding device 2 fixedly connected to one side of the top of the base 1, and a gas collection hood 3 fixedly connected to the upper part of the welding device 2; a processing box 4 fixedly connected to one side of the welding device 2, and a rotating tube 12 rotatably connected to the inner side of the processing box 4, with a filter cartridge 14 sleeved on the rotating tube 12; a drive motor 19 fixedly connected to one side of the bottom of the processing box 4 by bolts, and the bottom end of the rotating tube 12 passing through the bottom of the processing box 4 and being driven by the output shaft of the drive motor 19; and several air outlets 1 on the rotating tube 12. 3. A blower 7 is fixedly connected to one side of the outer wall of the treatment box 4 by bolts, and the inlet of the blower 7 is connected to one side of the treatment box 4. A rotary joint 5 is connected to one side of the top of the treatment box 4, and the top of the rotary joint 5 is connected to one side of the gas collection hood 3. Water tanks 10 are fixedly connected to both sides of the bottom of the treatment box 4, and a spray plate 15 is fixedly connected to one side of the lower part of the treatment box 4. A pump body 20 is fixedly connected to one side of the treatment box 4 by bolts. The outlets of the two water tanks 10 are connected to the inlet of the pump body 20, and the outlet of the pump body 20 is connected to one side of the spray plate 15.

[0023] First, the car seat frame material to be welded is placed on the welding equipment 2, and welding begins. Simultaneously, the fan 7 is started, effectively collecting and extracting the welding fumes generated during welding through the fume hood 3. The welding fumes enter the treatment chamber 4 via the rotary joint 5. During this process, the welding fumes are guided to the filter cartridge 14 for preliminary filtration and adsorption to remove particulate matter and some harmful gases. To further improve the filtration efficiency of the filter cartridge 14, the drive motor 19 starts synchronously, its output shaft driving the rotating tube 12 to rotate, thereby rotating the filter cartridge 14 fitted on it. This ensures that the welding fumes are evenly distributed on the surface of the filter cartridge 14, preventing local blockages that could affect the purification effect. At the same time, the pump 20 also starts operating, drawing clean water from the two water tanks 10 and transporting it through pipes to the spray plate 15. The spray plate 15 sprays the water into the treatment chamber 4 in a mist form. The sprayed water mist further captures fine particulate matter in the welding fumes, forming a wet purification process and improving the overall purification efficiency. After being sprayed, the exhaust gas continues to undergo further purification steps in the treatment chamber 4, while the spraying water flows back to the water tank 10 under gravity. There, it undergoes preliminary filtration before being recycled, reducing water waste. Throughout the process, the design of the rotary joint 5 ensures that the gas collection hood 3 maintains a stable gas transmission channel as it moves with the welding equipment 2, preventing interruption of welding fume collection due to movement.

[0024] Furthermore, a cover plate 11 is installed on one side of each of the two water tanks 10, and a door 9 is hinged to the outside of the treatment tank 4, allowing for convenient inspection, maintenance, and cleaning of the interior of the water tanks 10 and the treatment tank 4. This not only helps ensure the normal operation of the equipment but also facilitates timely replacement of the filter cartridge 14 or cleaning of the filter plate 16 inside the water tank 10, thereby ensuring the efficiency of welding fume purification and the recycling effect of water resources.

[0025] Furthermore, the top of the rotary joint 5 is connected to a top pipe 6, and one end of the top pipe 6 is connected to one side of the gas collection hood 3. The inlet of the fan 7 is connected to one side of the treatment box 4 through the outlet pipe 8, allowing the gas collection hood 3 to move flexibly without affecting the effective collection of welding fumes. The outlet pipe 8 connects the fan 7 to the treatment box 4, ensuring that welding fumes smoothly enter the treatment box 4 from the gas collection hood 3 and are evenly distributed around the filter cartridge 14 through the outlet holes 13 on the rotary pipe 12, improving the filtration effect while maintaining the airtightness and stability of the entire system.

[0026] Furthermore, the top end of the rotating tube 12 is connected to the bottom of the rotary joint 5 via a bearing sleeve, and the bottom end of the rotating tube 12 is connected to the bottom of the processing box 4 via a bearing sleeve, thus enabling the drive motor 19 to drive the rotating tube 12 and the filter cartridge 14 on it to rotate stably. This design avoids gas leakage problems caused by mechanical movement, while ensuring the structural strength and safety of the filter cartridge 14 under high-speed rotation, further improving the uniformity and efficiency of welding fume filtration.

[0027] Furthermore, filter plates 16 are slidably connected to the inner sides of both water tanks 10, and sliders 17 are fixedly connected to both sides of the filter plates 16. The sliders 17 are slidably connected to the inner walls of the water tanks 10 through grooves 18. The tops of both water tanks 10 are interconnected with the bottom of the treatment tank 4, facilitating the periodic removal of the filter plates 16 for cleaning or replacement to maintain the cleanliness of the sprayed water and prevent secondary pollution. In addition, the interconnected design between the tops of the two water tanks 10 and the bottom of the treatment tank 4 ensures that the sprayed water can effectively flow back to the water tanks 10 for preliminary filtration and reuse, reducing water waste.

[0028] Furthermore, the lower parts of the two water tanks 10 are interconnected via a connecting pipe 22. The inlet of the pump body 20 is connected to one end of the connecting pipe 22, and the outlet of the pump body 20 is connected to a connecting pipe 21. One end of the connecting pipe 21 passes through the side wall of the treatment tank 4 and is connected to one side of the spray plate 15. This enables the water pump to draw clean water from either water tank 10 and deliver it to the spray plate 15 via the connecting pipe 21. This design enhances the reliability of the system's water supply. Even if one water tank 10 malfunctions, the other water tank 10 can continue to supply water, ensuring the continuity of the spraying process. It also optimizes the water circulation path and improves the overall water resource utilization rate.

[0029] In summary:

[0030] First, the car seat frame material to be welded is placed on the welding equipment 2 fixed on one side of the top of the base 1, and the welding operation begins. Simultaneously, the fan 7 is started, and the welding fumes generated during the welding process are effectively collected and extracted through the fume hood 3. The welding fumes enter the treatment box 4 through the rotary joint 5. During this process, the welding fumes are guided to the filter cartridge 14 for preliminary filtration and adsorption to remove particulate matter and some harmful gases. To further improve the filtration efficiency of the filter cartridge 14, the drive motor 19 is started synchronously, and its output shaft drives the rotating tube 12 to rotate, thereby driving the filter cartridge 14 fitted on it to rotate as well, so that the welding fumes are evenly distributed on the surface of the filter cartridge 14, avoiding local blockage that affects the purification effect. At the same time, the pump body 2... The 0 system also starts operating, drawing clean water from the two water tanks 10 through the connecting pipe 22 at its inlet. After preliminary filtration by the filter plate 16, the clean water is transported to the spray plate 15 through the connecting pipe 21. The spray plate 15 sprays the water into the treatment tank 4 in a mist form. The sprayed water mist can further capture fine particles in the welding fume, forming a wet purification process and improving the overall purification efficiency. The exhaust gas after spraying continues to complete subsequent purification steps in the treatment tank 4, while the spraying water flows back to the bottom of the treatment tank 4 under gravity and flows back into the water tank 10 through the channel between the bottom of the treatment tank 4 and the top of the two water tanks 10, realizing the recycling of water resources. Throughout the process, the design of the rotary joint 5 ensures that the gas collection hood 3 can still function when moving with the welding equipment 2. A stable gas transmission channel is maintained, ensuring that the collection of welding fumes is not interrupted by movement. Furthermore, the top pipe 6 serves as the connecting pipe between the rotary joint 5 and the gas collection hood 3, and together with the exhaust pipe 8, connects the fan 7 to one side of the treatment box 4. This ensures that welding fumes smoothly enter the treatment box 4 from the gas collection hood 3 and are evenly distributed around the filter cartridge 14 through the exhaust holes 13 on the rotary pipe 12, improving the filtration effect while maintaining the airtightness and stability of the entire system. The top end of the rotary pipe 12 passes through the top of the treatment box 4 via a bearing sleeve and is connected to the bottom of the rotary joint 5. Its bottom end also passes through the bottom of the treatment box 4 via a bearing sleeve. This structural design not only enables the drive motor 19 to drive the rotary pipe 12 and the filter cartridge 14 to rotate stably, but also avoids… The mechanical movement prevents gas leakage while ensuring the structural strength and safety of the filter cartridge 14 under high-speed rotation. For easy maintenance and cleaning, a cover plate 11 is installed on one side of each of the two water tanks 10, and a door 9 is hinged to the outside of the treatment box 4, allowing staff to easily open the door 9 to replace or clean the filter cartridge 14 and other components. The cover plate 11 can also be used to regularly clean or replace the filter plate 16 inside the water tank 10 to prevent secondary pollution. Filter plates 16 are slidably connected to the inside of each of the two water tanks 10, and sliders 17 are fixedly connected to both sides of the filter plate 16. They are slidably connected to the inner wall of the water tank 10 through a sliding groove 18. This structure facilitates quick disassembly and replacement of the filter plate 16, improving maintenance efficiency.The lower parts of the two water tanks 10 are connected to each other through a connecting pipe 22. The inlet of the pump body 20 is connected to one end of the connecting pipe 22, and the outlet is connected to the spray plate 15 through a connecting pipe 21. This design enhances the reliability of the system water supply. Even if one water tank 10 has a problem, the other water tank 10 can still continue to supply water, ensuring the continuity of the spraying process. At the same time, it optimizes the water circulation path and improves the overall water resource utilization rate. A complete welding fume purification system is constructed by setting up a gas collection hood 3, a fan 7, a rotary joint 5, a jacking pipe 6, an exhaust pipe 8, a treatment box 4, a filter cartridge 14, a rotating pipe 12, and a drive motor 19. This system can efficiently treat the fumes generated during welding, significantly improve workshop air quality, protect the health of operators, and meet the environmental emission and occupational health and safety requirements of modern manufacturing. Secondly, the rotating design of the filter cartridge 14 in conjunction with the rotating pipe 12 not only improves filtration efficiency but also extends the service life of the filter cartridge 14, reducing maintenance frequency and costs. The spray system composed of the spray plate 15 and the water tank 10 achieves wet dust removal, further enhancing the exhaust gas treatment effect. Furthermore, the water circulation structure improves water resource utilization, conforming to green environmental protection standards. The system incorporates a color-coded manufacturing concept. The filter plate 16 inside the water tank 10, combined with the sliding connection between the slider 17 and the slide groove 18, facilitates regular removal of the filter plate 16 for cleaning or replacement, maintaining the cleanliness of the spray water and preventing secondary pollution. The two water tanks 10 are interconnected via a connecting pipe 22, and a circulating water supply is achieved through the connecting pipe 21 between the pump body 20 and the spray plate 15, enhancing the reliability of the system's water supply. Even if one water tank 10 malfunctions, the other water tank 10 can continue to supply water, ensuring the continuity of the spraying process. The cover plate 11 and the door 9 facilitate daily maintenance and repair, improving the maintainability of the equipment. The rotary joint 5 and the rotating pipe 12 are connected through a bearing sleeve, ensuring the system's sealing and stability under dynamic operation.
