A sliding rod 404 is fixed between the other sides of the two sets of side plates 401. A movable plate 405 is threadedly connected to the one-way lead screw 403. The movable plate 405 is slidably connected to the sliding rod 404 and can move through the threaded movement of the one-way lead screw 403 and the movable plate 405, facilitating the back-and-forth movement of the movable plate 405 on the sliding rod 404. A protective cover 406 is fixed to the outer end of the movable plate 405. Furthermore, a drive motor 407 is fixed inside the protective cover 406, and a turntable 408 is fixed at the output end of the drive motor 407. A grinding stone 409 is bolted to the surface of the turntable 408, which facilitates the drive motor 407 to drive the grinding stone 409 to rotate, so that the grinding stone 409 can grind the weld seam of the stainless steel plate. The surface of the processing box 1 has a first slot 6 at both ends. The outer side of the surface of the processing box 1 is fixed with a fixing block 7 at both the upper and lower ends of the first slot 6. A bidirectional screw 8 is rotatably connected to the fixing block 7 on one side of the processing box 1 and threadedly connected between the upper grinding component 4 and the lower grinding component 5. A positioning rod 9 is fixed to the fixing block 7 on the other side of the processing box 1 and slidably connected to the upper grinding component 4 and the lower grinding component 5. The bidirectional screw 8 can drive the upper grinding component 4 and the lower grinding component 5 to move threadedly, so as to adjust the distance between the upper grinding component 4 and the lower grinding component 5, which is convenient for the use of stainless steel plates of different thicknesses.

[0021] Please see Figure 1-4Dust removal components 10 are installed on the surfaces of the upper grinding assembly 4 and the lower grinding assembly 5. The dust removal component 10 includes a water pump 1001, which is fixed to the side of the processing tank 1. One end of the water pump 1001 is connected to the bottom of the processing tank 1 through a water guide pipe 1002, and the other end of the water pump 1001 is connected to a first drain pipe 1003. The end of the first drain pipe 1003 is connected to a water collection pipe 1004 fixed at both ends of the movable plate 405. Water spray heads 1005 are evenly installed below the water collection pipe 1004 and are arranged at an angle. The two sets of water collection pipes 1004 are connected by a connecting pipe 1007. The middle part of the first drain pipe 1003 is connected to the water collection pipe 1004 on the lower grinding assembly 5 through a second drain pipe 1006. The dust removal assembly 10 can spray water to reduce dust generated on the polishing stone 409 through the water spray head 1005, avoiding the problem of dust splashing. Both ends of the inside of the treatment box 1 are fixed with discharge plates 11, and a dirt collection frame 12 is set in the middle of the discharge plate 11. The bottom side of the dirt collection frame 12 is provided with a water outlet hole 13. The inside of the dirt collection frame 12 is provided with a filter screen 14. The dirt collection frame 12 is connected to the treatment box 1 by sliding connection, and the dirt collection frame 12 is connected to the filter screen 14 by snap-fit ​​disassembly and installation connection, which makes it convenient to filter the dirty water after it falls through the dirt collection frame 12, so that the waste is left in the dirt collection frame 12 for easy collection and treatment. At the same time, the surface of the dirt collection frame 12 is provided with a water outlet hole 13, which makes it easy for the water to flow out and be reused.

[0022] Please see Figure 1-4 A positioning component 15 is installed on the side of the processing box 1. The positioning component 15 includes a second slot 1501. The second slot 1501 is opened at both ends of one side of the processing box 1, and a pressing plate 1502 is slidably connected to the second slot 1501. A horizontal plate 1504 is fixed to the outer end of the two sets of pressing plates 1502. A rubber pad 1503 is bonded to the bottom of the pressing plate 1502. An adjusting screw 1505 rotatably connected to the middle of the horizontal plate 1504 is threadedly connected to the fixing block 7. The adjusting screw 1505 on the positioning component 15 can be used to facilitate the threaded movement of the adjusting screw 1505 and the horizontal plate 1504, so that the horizontal plate 1504 drives the pressing plates 1502 at both ends to slide on the second slot 1501, so that the rubber pad 1503 under the pressing plate 1502 can press the stainless steel plate body, so as to position the stainless steel plate body during grinding.

[0023] Working principle: First, when using, place the weld seam of the stainless steel plate in the middle of the processing box 1, and rotate the adjusting screw 1505 on the positioning component 15 so that the adjusting screw 1505 moves with the thread of the horizontal plate 1504. Then, under the limiting action of the second slot 1501, the pressing plates 1502 at both ends of the horizontal plate 1504 slide on the second slot 1501, thereby causing the pressing plates 1502 at both ends of the horizontal plate 1504 to move downward, which facilitates limiting and pressing the two ends of the stainless steel plate and improves the stability of the stainless steel plate during grinding.

[0024] Then, by rotating the bidirectional lead screw 8, the bidirectional lead screw 8 moves threadedly with the side plates 401 on the upper grinding assembly 4 and the lower grinding assembly 5, so that the upper grinding assembly 4 and the lower grinding assembly 5 move towards each other, making it easier to fit the grinding stone 409 to the weld. Then, by opening the drive motor 407 inside the protective cover 406, the drive motor 407 drives the grinding stone 409 to rotate through the turntable 408, so as to grind the stainless steel weld. At the same time, with the use of the servo motor 402, the servo motor 402 drives the movable plate 405 to move threadedly through the unidirectional lead screw 403, so that the movable plate 405 moves back and forth on the slide bar 404, thereby facilitating the grinding work of the device on the weld.

[0025] During grinding, the water pump 1001 on the dust removal assembly 10 can be turned on, allowing the water pump 1001 to absorb the water at the bottom of the processing tank 1 through the water guide pipe 1002, and guide the water into the water collection pipe 1004 through the first drain pipe 1003. This facilitates the water spray head 1005 below the water collection pipe 1004 to spray water onto the grinding area to reduce dust and prevent dust from splashing. The middle part of the first drain pipe 1003 is connected to the water collection pipe 1004 on the lower grinding assembly 5 through the second drain pipe 1006, so that the device can spray water from top to bottom to reduce dust. The falling dust and water will pass through the inclined discharge plate 11 so that the dirty water falls into the dirty collection frame 12, where the filter screen 14 inside the dirty collection frame 12 can filter the water and dust for collection. The dirty collection frame 12 has a water outlet hole 13 on its lower side, which facilitates the recycling of the water after it flows out. This is the operating principle of the grinding equipment.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
