[0027] Specifically, the first motor 11 is started to drive the support wheel 9 to rotate, and the steel plate is moved to the right through cooperation with the top wheel 10. The steel plate is bent through the operation of the former 3, and then the electric push rod 6 is started to drive the welding gun 7 to move downward to weld the bent steel plate into a spiral welded pipe 4. In the process of moving the steel plate, the second motor 17 is started to drive the first rotating rod 13 to rotate, and the other rotating rod 13 also rotates through the transmission of the transmission belt 16 on the belt pulley 15, thereby driving the two side grinding rollers 14 to rotate to polish and clean the two sides of the steel plate to remove burrs.

[0028] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application. Figure 3 And Figure 4The first support base 12 has sliding plates 18 slidably connected to both sides of the inner wall of the right end. Cleaning sponges 19 are fixedly connected to one end of the inner side of each sliding plate 18. The sliding plates 18 are connected to the inner wall of the first support base 12 by springs 20. One end of the spring 20 is connected to the sliding plate 18, and the other end of the spring 20 is connected to the inner wall of the first support base 12. The top right side of the first base plate 1 is fixedly connected to the second support base 21. The inner wall of the second support base 21 is rotatably connected to the reciprocating screw 22. The outer wall of the reciprocating screw 22 is threadedly connected to the moving plate 24. The inner wall of the moving plate 24 is fixedly connected to the fan 25. The left end of the moving plate 24 is slidably connected to the inner wall of the second support base 21. The front end of the second support base 21 is fixedly connected to the third motor 23. The front end of the reciprocating screw 22 is fixedly connected to the drive end of the third motor 23.

[0029] Specifically, after the steel plate is polished on both sides, the spring force of the spring 20 is activated, which drives the sliding plate 18 to move inward, thereby driving the cleaning sponge 19 to move inward to clean the debris remaining on both sides of the steel plate. The third motor 23 is activated, which drives the reciprocating screw 22 to rotate, thereby driving the fan 25 on the moving plate 24 to move back and forth on the reciprocating screw 22 to remove dust from the surface of the steel plate, further improving the cleaning effect.

[0030] Working principle: First, by activating the first motor 11, it drives the support wheel 9 to rotate, working in conjunction with the top wheel 10 to move the steel plate to the right. Next, under the action of the forming device 3, the steel plate is bent. Subsequently, the activation of the electric push rod 6 causes the welding torch 7 to move downwards, welding the bent steel plate into a spiral welded pipe 4. During the movement of the steel plate, the activation of the second motor 17 drives the primary rotating rod 13 to rotate. The rotating rod 13 on the other side also rotates synchronously through the transmission mechanism of the pulley 15 and the transmission belt 16, thereby driving the grinding rollers 14 on both sides to rotate, grinding and cleaning both sides of the steel plate to remove burrs. Secondly, after completing the grinding operation on both sides of the steel plate, the elasticity activation mechanism of the spring 20 causes the sliding plate 18 to move inwards, thereby pushing the cleaning sponge 19 inwards to remove residual debris from both sides of the steel plate. At the same time, the third motor 23 is started to drive the reciprocating screw 22 to rotate, so that the fan 25 installed on the moving plate 24 reciprocates on the reciprocating screw 22 to remove dust from the surface of the steel plate, thereby further improving the cleaning effect.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
