A limiting hole 42 is provided at one end of the connecting block 10. Two water pipes 19 are fixedly connected to the upper end of the connecting block 10. The water pipes 19 are connected to the U-shaped cavity 16. Through the arrangement of the plurality of heating rods 17 in the plurality of U-shaped cavities 16, the temperature of the cooling water entering the plurality of U-shaped cavities 16 is reduced in a gradient manner, thereby realizing a slow cooling of the surface of the tungsten strip 3 after cutting. The cooling water entering the U-shaped cavity 16 will cool the heat-conducting copper plate 18 that absorbs the heat from the surface of the tungsten strip 3. The heat-conducting copper plate 18 is in direct contact with the surface of the tungsten strip 3, so that the temperature of the cooling water directly penetrates into the tungsten strip 3 through the heat-conducting copper plate 18, thereby dissipating heat and cooling the tungsten strip 3. The limiting guide mechanism includes a T-shaped vertical rod 20, one end of the T-shaped vertical rod 20 is slidably connected to the T-shaped slot 21, the T-shaped slot 21 is opened in the connecting plate 8, a second spring 26 is fixedly connected to the T-shaped slot 21, the other end of the second spring 26 is fixedly connected to the T-shaped vertical rod 20, and a limiting rod 30 is movably connected to the T-shaped vertical rod 20. One end of the limiting rod 30 is clamped in the limiting hole 42, and the limiting spring 31 is sleeved on the outside of the limiting rod 30. One end of the limiting spring 31 is fixedly connected to the T-shaped vertical rod 20, and the other end is fixedly connected to the limiting rod 30. By pushing the connecting block 10 to move, the clamping end of the limiting rod 30 is clamped to the limiting hole 42 The connecting block 10 can be limited in position, and a sliding cavity 25 is provided in the end of the T-shaped vertical rod 20 away from the connecting plate 8. A T-shaped guide plate 24 is slidably connected in the sliding cavity 25. The T-shaped guide plate 24 is provided with an arc-shaped groove at the end away from the T-shaped vertical rod 20. After the two T-shaped guide plates 24 are in contact with each other, the two arc-shaped grooves can limit and guide the traction rope 28. The T-shaped guide plate 24 can be moved by toggling it. After the traction rope 28 is set in the two arc-shaped grooves, the toggling of the T-shaped guide plate 24 is released. At this time, under the elastic force of the connecting spring 23, the opposite ends of the two T-shaped guide plates 24 will be in contact with each other again; The cam 32 is fixedly connected to the sliding cavity 25, and the other end of the connecting spring 23 is fixedly connected to the T-shaped guide plate 24. The elastic force of the limit spring 31 is greater than the elastic force of the connecting spring 23. The outside of the limit rod 30 is fixedly connected to the pull rope 32. The pull rope 32 extends into the sliding cavity 25 away from one end of the limit rod 30 and is fixedly connected to the T-shaped guide plate 24. The limit rod 30 is provided with a clamping hole 35 on the outside, and a clamping rod 34 is clamped in the clamping hole 35. The upper end of the clamping rod 34 extends into the guide groove 36 and is fixedly connected to the extrusion rod 29. The guide groove 36 is provided in the T-shaped vertical rod 20. The extrusion rod 29 is slidably connected to the guide groove 36. The extrusion rod 29 is inclined near one end of the U-shaped rod 22. When the inclined end of the extrusion rod 29 contacts the U-shaped rod 22, the extrusion rod 29 will drive the clamping rod 34 to move, and the clamping end of the clamping rod 34 will be disengaged from the clamping hole 35. A third spring 33 is fixedly connected in the guide groove 36, and the other end of the third spring 33 is fixedly connected to the extrusion rod 29. Under the elastic force of the second spring 26, the T-shaped vertical rod 20 will move to the right, pulling the limiting rod 30 to move. When the clamping hole 35 moves to the position of the clamping rod 34, the clamping end of the clamping rod 34 will be clamped into the clamping hole 35 under the elastic force of the third spring 33, thereby limiting the limiting rod 30. The liquid supply mechanism includes a water tank 38, and the upper and lower ends of the water tank 38 are fixedly connected to a circulation pump 40 and a drain pipe 39. The input end of the circulation pump 40 extends into the water tank 38, and the output end is fixedly connected to the water inlet pipe 41. The water inlet pipe 41 and the drain pipe 39 are fixedly connected to the corresponding water pipe 19 at the end away from the water tank 38. A cooling fin 37 is fixedly installed in the water tank 38. The specific model of the cooling fin 37 is TEC1-12706 produced by Shenzhen Tengshunwei Intelligent Co., Ltd. The water inlet pipe 41 and the drain pipe 39 are elastic telescopic hoses.

[0031] Working principle: when in use, the roller with the tungsten belt 3 wound on it is connected to the mounting rod 45, and the roller with the tungsten belt 3 wound on it can be limited by screwing the nut 12 to the outside of the mounting rod 45, and the tungsten belt 3 is pulled out and passed through the two first guide rollers 4. After passing through, the two U-shaped plates 46 are passed through the third guide roller 7 and the second guide roller 14 in turn, and connected to the tungsten belt 3 through screws, and the two transmission motors 43 are turned on to drive the cross-shaped mounting rods 44 connected to their output ends to rotate, and the rotation of the cross-shaped mounting rods 44 drives the winding roller 13 to rotate, and the rotating winding roller 13 rewinds the traction rope 28, and the laser cutting gun 6 is turned on. When the traction rope 28 is wound and moved, it will drive the tungsten belt 3 to move. When the tungsten belt 3 moves to the lower side of the laser cutting gun 6, the tungsten belt 3 will be cut into two parts, and the two parts of the tungsten belt 3 will be pulled in opposite directions by the corresponding traction ropes 28 respectively. When the U-shaped plate 46 drives the tungsten strip 3 into the space between the two connecting blocks 10 and contacts the two T-shaped guide plates 24, then as the towing rope 28 is continuously pulled, the U-shaped plate 46 will push the two T-shaped guide plates 24 to move leftward. The movement of the T-shaped guide plates 24 drives the T-shaped vertical rods 20 to move along the T-shaped grooves 21. At this time, one end of the limiting rod 30 will gradually disengage from the limiting hole 42. When the clamping end of the limiting rod 30 completely disengages from the limiting hole 42, then under the elastic force of the first spring 27, the two connecting blocks 10 will move synchronously and contact the tungsten strip 3. As the U-shaped plate 46 continuously pushes the T-shaped guide plates 24 to move, the left end of the extrusion rod 29 will contact the U-shaped rod 22 and be extruded to move. The movement of the extrusion rod 29 drives the clamping rod 34 to move. When the clamping end of the clamping rod 34 moves out of the clamping hole 35, then under the elastic force of the limiting spring 31, the limiting rod 30 will move rightward and drive the pull rope 32 to move. At this time, the T-shaped guide plates 24 will be pulled by the pull rope 32 and retracted into the sliding cavity 25, and the U-shaped plate 46 can drive the tungsten strip 3 to be wound around the outside of the winding roller 13; Meanwhile, after the two connecting blocks 10 contact the tungsten strip, several heating rods 17 and the circulation pump 40 will be started. The circulation pump 40 pumps the cooling water in the water tank 38 into the water inlet pipe 41, and then the water enters several U-shaped cavities 16 through the water inlet pipe 41. After the cooling water enters the U-shaped cavities 16, it will pass through several heating rods 17. The several heating rods 17 heat the cooling water. Through the arrangement of the several heating rods 17 in the several U-shaped cavities 16, the temperature of the cooling water entering the several U-shaped cavities 16 decreases in a gradient manner, realizing the slow cooling of the surface of the cut tungsten strip 3; The cooling water entering the U-shaped cavities 16 will cool the heat-conducting copper plates 18 that have absorbed the heat on the surface of the tungsten strip 3. The cooled cooling water will enter the drain pipe 39 through another water guide pipe 19. The cooling water entering the drain pipe 39 will re-enter the water tank 38 and be cooled by several cooling fins 37. After the winding of the cut tungsten strip 3 is completed, the winding roller 13 wound with the cut tungsten strip 3 can be removed by unscrewing the nut 12.
