[0016] The technical effects and advantages of the present invention are as follows:

[0017] 1. Before welding, the welds of the two stainless steel plates to be welded can be butted at the positioning grooves. Then, start the first electric push rod. The output end of the first electric push rod drives the fixed plate to move downward through the first connecting piece. The two fixed plates respectively fix the two stainless steel plates to be welded, avoiding the shaking of the stainless steel plates to be welded and affecting the subsequent welding effect.

[0018] 2. After the two stainless steel plates to be welded are fixed, the staff can start the second electric push rod on the guide seat. The output end of the second electric push rod drives the mounting plate to move downward through the second connecting piece. The welding head is installed on the mounting plate, thereby driving the welding head to move downward, which is convenient for adjusting the height position of the welding head to weld stainless steel plates of different thicknesses.

[0019] 3. After the welding head is adjusted to the appropriate height position, the staff can start the first motor. The output end of the first motor is connected to the transmission lead screw, thereby driving the transmission lead screw to rotate. Under the action of the lead screw nut, the sliding block and the guide rail, the guide seat can be driven to slide, and then the welding head below the guide seat can be driven to move, and the two stainless steel plates can be welded together to realize the welding function of the welding device for the production of stainless steel products.

[0020] 4. When the welding head is moving, the staff can start the air extraction pump, so that the waste gas generated during the welding process will be transported to the inside of the filter box through the wind hood, the first air delivery pipe and the second air delivery pipe. The waste gas entering the filter box will first be filtered by the first filter plate to remove dust and impurities, and then adsorbed by the first activated carbon plate to remove harmful substances, and finally discharged through the exhaust pipe, which can purify the waste gas generated during the welding process.

[0021] 5. When the first filter plate and the first activated carbon plate need to be replaced and maintained, the staff can start the third electric push rod. The output end of the third electric push rod drives the push plate to eject through the third connecting piece, and then drives the second filter plate to move towards the first filter plate, and extrudes the first filter plate from the end of the filter box away from the second filter plate. The second filter plate will replace the first filter plate and enter the inside of the filter box. Then the output end of the third electric push rod drives the push plate to contract through the third connecting piece. Since an iron sheet is fixedly installed on the outer wall of the second filter plate and a magnetic sheet is fixedly installed on the inner wall of the filter box, and the iron sheet is magnetically connected to the magnetic sheet, the second filter plate can be quickly fixed inside the filter box. In addition, the thrust provided by the third electric push rod for the push plate can drive the iron sheet to slide on the magnetic sheet. Similarly, the second activated carbon plate can replace the first activated carbon plate inside the filter box. The above method can conveniently replace the filter plate and the activated carbon plate;

[0022] 6. After the first filter plate and the first activated carbon plate are replaced, the staff can insert the first infusion tube into the storage bucket outside for storing the filter plate cleaning agent, and then start the first booster pump, so that the filter plate cleaning agent inside the storage bucket will be transported to the first liquid inlet pipe through the first infusion tube and the second infusion tube, and then the first liquid inlet pipe will transport the filter plate cleaning agent to the inside of the liquid mixing tank to wait for liquid mixing. This method can conveniently transport the filter plate cleaning agent inside the storage bucket to the inside of the liquid mixing tank quickly;

[0023] 7. After the filter plate cleaning agent is transported to the inside of the liquid mixing tank, the staff connects the external water pipe to the second liquid inlet pipe, and then transports the water liquid to the liquid mixing tank and starts the second motor. The second motor drives the first stirring shaft to rotate through the coupling. A first pulley is fixedly installed on the first stirring shaft, a second pulley is fixedly installed on the second stirring shaft, and a transmission belt is arranged between the first pulley and the second pulley, so that the first stirring shaft drives the second stirring shaft to rotate through the first pulley, the transmission belt and the second pulley. A first stirring blade is fixedly connected to the outer wall of the first stirring shaft, and a second stirring blade is fixedly connected to the outer wall of the second stirring shaft, thereby driving the first stirring blade and the second stirring blade to rotate and strongly stirring the filter plate cleaning agent and the water liquid, so that the filter plate cleaning agent and the water liquid are fully mixed to achieve rapid liquid mixing;

[0024] 8. After the filter plate cleaning agent is fully mixed with the aqueous solution to form a cleaning solution, the staff can place the first filter plate on the leak plate inside the cleaning tank, and then start the second booster pump to transport the cleaning solution inside the liquid preparation tank to the liquid guide pipe. Subsequently, the cleaning solution passes through the third infusion pipe and the fourth infusion pipe and is finally discharged into the cleaning tank through the liquid outlet pipe for soaking the first filter plate. After the soaking is completed, the sixth control valve can be opened to discharge the soaking liquid inside through the drain pipe, and then the first filter plate can be rinsed with an external water gun. The flushed sewage will pass through the leak plate and be discharged through the drain pipe. Subsequently, the first filter plate is dried. After the first filter plate is dried, the staff can insert the first filter plate into the corresponding placement frame through the slot and then replace it into the filter tank. The above method can effectively clean the filter plate, enabling the filter plate to be used multiple times. BRIEF DESCRIPTION OF THE DRAWINGS

When the welding head 215 is moving, the staff can start the air extraction pump 303, so that the waste gas generated during the welding process will be transported to the inside of the filter box 306 through the wind hood 301, the first air pipe 304 and the second air pipe 305. The waste gas entering the inside of the filter box 306 will first be filtered by the first filter plate 309 to remove dust and impurities, and then adsorbed by the first activated carbon plate 310 to remove harmful substances, and finally discharged through the exhaust pipe 307, which can purify the waste gas generated during the welding process;When the first filter plate 309 and the first activated carbon plate 310 need to be replaced and maintained, the staff can activate the third electric push rod 404. The output end of the third electric push rod 404 drives the push plate 406 to eject through the third connecting piece 405, thereby driving the second filter plate 403 to move towards the first filter plate 309, and extruding the first filter plate 309 from the end of the filter box 306 away from the second filter plate 403. The second filter plate 403 will replace the first filter plate 309 and enter the interior of the filter box 306. Then, the output end of the third electric push rod 404 drives the push plate 406 to contract through the third connecting piece 405. Since an iron sheet 407 is fixedly installed on the outer wall of the second filter plate 403 and a magnetic sheet 408 is fixedly installed on the inner wall of the filter box 306, the iron sheet 407 is magnetically connected to the magnetic sheet 408, thereby quickly fixing the second filter plate 403 inside the filter box 306. In addition, the thrust provided by the third electric push rod 404 for the push plate 406 can drive the iron sheet 407 to slide on the magnetic sheet 408. Similarly, the second activated carbon plate 409 can replace the first activated carbon plate 310 inside the filter box 306. The above method can conveniently replace the filter plate and the activated carbon plate; after the first filter plate 309 and the first activated carbon plate 310 are replaced, the staff can insert the first infusion tube 502 into the storage bucket outside for storing the filter plate cleaning agent, and then activate the first booster pump 501, so that the filter plate cleaning agent inside the storage bucket will be transported to the first liquid inlet pipe 602 through the first infusion tube 502 and the second infusion tube 503, and then the first liquid inlet pipe 602 transports the filter plate cleaning agent into the liquid preparation tank 601 for waiting for liquid preparation. This method facilitates the rapid transportation of the filter plate cleaning agent inside the storage bucket to the liquid preparation tank 601; after the filter plate cleaning agent is transported into the liquid preparation tank 601, the staff connects the external water pipe to the second liquid inlet pipe 604, and then transports the water liquid into the liquid preparation tank 601 and activates the second motor 607. The second motor 607 drives the first stirring shaft 609 to rotate through the coupling 608. A first pulley 610 is fixedly installed on the first stirring shaft 609, a second pulley 612 is fixedly installed on the second stirring shaft 613, and a transmission belt 611 is arranged between the first pulley 610 and the second pulley 612, so that the first stirring shaft 609 drives the second stirring shaft 613 to rotate through the first pulley 610, the transmission belt 611 and the second pulley 612. A first stirring blade 614 is fixedly connected to the outer wall of the first stirring shaft 609, and a second stirring blade 615 is fixedly connected to the outer wall of the second stirring shaft 613, thereby driving the first stirring blade 614 and the second stirring blade 615 to rotate and strongly stir the filter plate cleaning agent and the water liquid, so that the filter plate cleaning agent and the water liquid are fully mixed to achieve rapid liquid preparation;After the filter plate cleaning agent is fully mixed with the water solution to form a cleaning solution, the staff can place the first filter plate 309 on the leak plate 710 inside the cleaning tank 707, and then start the second booster pump 703, which can transport the cleaning solution inside the liquid preparation tank 601 to the liquid guide pipe 701. Subsequently, the cleaning solution passes through the third infusion pipe 704 and the fourth infusion pipe 705 and finally is discharged into the cleaning tank 707 through the liquid outlet pipe 711 for soaking the first filter plate 309. After the soaking is completed, the sixth control valve 709 can be opened to discharge the soaking liquid inside through the drain pipe 708. Then, the first filter plate 309 is rinsed with an external water gun, and the flushed sewage will pass through the leak plate 710 and be discharged through the drain pipe 708. Subsequently, the first filter plate 309 is dried. After the first filter plate 309 is dried, the staff can insert the first filter plate 309 into the corresponding placement frame 401 through the slot 402 and then replace it in the filter tank 306. The above method can effectively clean the filter plate, enabling the filter plate to be used multiple times.
