[0019] In one example of the present invention, when in use, the steel template is smoothly placed on the conveying roller 3 along the vertical block 28, and the horizontal axis 2 at one end is driven by a stepper motor, and the double-track pulley 30 at the end of the horizontal axis 2 rotates synchronously therewith, and then the horizontal axis 2 and the conveying roller 3 at the remaining positions are driven to rotate synchronously through the set synchronous belt 31, thereby conveying the steel template at one end.

[0020] like Figure 1 As shown, as another preferred embodiment of the present invention, the horizontal adjustment mechanism 200 includes a sleeve 4, a movable plate 5 and a protective pad 6; The sleeve 4 is fixedly mounted on the opposite sides of the base 1, and a movable plate 5 is slidably mounted on the sleeve 4 and is pushed by a telescopic member built into the sleeve 4; A protective pad 6 is bonded to the working end of the movable plate 5 , and the protective pad 6 is made of rubber material to increase the static friction force when pressed tightly.

[0023] In one example of the present invention, the driving motor 29 is connected to the end of the driving screw 9 through a coupling, and when the driving motor 29 is working, the driving screw 9 is driven to rotate along the support rod 7 through the arranged coupling, and the driving screw 9 pushes the movable blocks 10 on both sides to slide synchronously along the positioning column 8, and the cross plate 11 and the laser locator 12 move synchronously therewith, and according to the positioning result of the laser locator 12, the horizontal movement process of the cross plate 11 is precisely adjusted.

[0024] like Figure 1 and Figure 3As shown, as another preferred embodiment of the present invention, the cooling system 400 includes a water inlet pipe 15, a threaded pipe 16, a liquid infusion pipe 17 and a cooling ring 18; The threaded tube 16 is arranged outside the laser generator 14, and the top end of the threaded tube 16 is connected to an external water tank through a water inlet pipe 15; The working end of the laser generator 14 is sleeved with a cooling ring 18 , which is connected to the threaded tube 16 via an infusion tube 17 , and a drainage pipe is also connected to the side of the cooling ring 18 .

[0025] In one example of the present invention, when the laser generator 14 is working, the coolant enters the threaded tube 16 along the water inlet pipe 15, and takes away the heat generated by the laser generator 14 when it is working while flowing along the threaded tube 16. At the same time, the coolant also flows along the infusion tube 17 and the cooling ring 18, and is finally discharged to the outside through the drain pipe.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the adaptive adjustment mechanism 500 includes an incomplete gear 20, a double-sided toothed plate 21, an elastic support member 22, an outer gear ring 23, a positioning ring 24, a connecting rod 26 and a movable baffle 27; The incomplete gear 20, the double-sided toothed plate 21 and the outer gear ring 23 are all arranged in the chamber inside the transverse plate 11, the double-sided toothed plate 21 is meshed with the incomplete gear 20 and the outer gear ring 23 arranged on both sides, and the ends of the double-sided toothed plate 21 are also installed with elastic support members 22; A positioning ring 24 is coaxially arranged on the inner side of the outer gear ring 23, and a plurality of connecting rods 26 are hinged on the inner side of the outer gear ring 23. A movable baffle 27 is hinged on the side of the positioning ring 24. The movable baffle 27 is connected to the connecting rod 26 so that when the outer gear ring 23 rotates, the movable baffle 27 is pushed by the arranged connecting rod 26 to swing along the positioning ring 24. A sealing ring 25 is arranged between the outer gear ring 23 and the positioning ring 24 to prevent leakage.

[0027] In one example of the present invention, when the built-in temperature sensor monitors the temperature change of the laser generator 14, the drive motor 19 drives the incomplete gear 20 to rotate, and the incomplete gear 20 pushes the double-sided toothed plates 21 to slide in the chamber. The elastic support member 22 is elastically deformed under force, and the double-sided toothed plates 21 also push the outer gear ring 23 and the sealing ring 25 to rotate along the positioning ring 24. At the same time, the outer gear ring 23 also pushes the connecting rods 26 at multiple positions to swing in the plane, and each connecting rod 26 pushes the movable baffle 27 at the corresponding position to swing along the positioning ring 24. By adjusting the adjacent positions of the multiple movable baffles 27, the flow rate of the coolant passing through the positioning ring 24 is changed, so that when the temperature of the laser generator 14 is too high, the flow rate of the coolant is accelerated, and when the temperature of the laser generator 14 is low, the flow rate of the coolant is slowed down, so as to ensure that the laser generator 14 is within a controllable temperature range.

[0028] In summary, when in use, the steel template is smoothly placed on the conveying roller 3 along the vertical block 28, and the horizontal axis 2 at one end is driven by a stepper motor, and the double-track pulley 30 at the end of the horizontal axis 2 rotates synchronously, and then the horizontal axis 2 and the conveying roller 3 at the other positions are driven to rotate synchronously through the arranged synchronous belt 31, so as to convey the steel template at one end. When the steel template moves to the designated position, the telescopic member is driven to work through the arranged operating platform 32, and the telescopic member pushes the movable plate 5 to slide along the sleeve 4, and the arranged protective pad 6 is used to fix it without damaging the steel template, and the driving When the motor 29 is working, the driving screw 9 is driven by the arranged coupling to rotate along the support rod 7, and the driving screw 9 pushes the movable blocks 10 on both sides to slide synchronously along the positioning column 8, and the cross plate 11 and the laser locator 12 move synchronously accordingly, and according to the positioning result of the laser locator 12, the horizontal movement process of the cross plate 11 is accurately adjusted. After reaching the work station, the laser generator 14 works to cut the steel template. At the same time, the coolant enters the threaded pipe 16 along the water inlet pipe 15, and takes away the heat generated by the laser generator 14 when it is working while flowing along the threaded pipe 16. At the same time, the coolant also flows along the infusion tube 17 and the cooling ring 18, and is finally discharged outward through the drain pipe. When the built-in temperature sensor monitors the temperature change of the laser generator 14, the drive motor 19 drives the incomplete gear 20 to rotate, and the incomplete gear 20 pushes the double-sided toothed plate 21 to slide in the chamber. The elastic support member 22 is elastically deformed under force, and the double-sided toothed plate 21 also pushes the outer gear ring 23 and the sealing ring 25 to rotate along the positioning ring 24. At the same time, the outer gear ring 23 also pushes the connecting rods 26 at multiple positions to swing in the plane. Each connecting rod 26 pushes the movable baffles 27 at the corresponding position to swing along the positioning ring 24. By adjusting the adjacent positions of the multiple movable baffles 27, the flow rate of the coolant passing along the positioning ring 24 is changed to adjust the temperature range of the laser generator 14. The cutting device is not only convenient for loading and unloading, but also has high stability during the cutting process, which can improve the cutting accuracy. At the same time, the cooling flow rate can be automatically adjusted as needed to accurately control the working temperature of the laser generator 14, so that it is in a suitable ambient temperature, ensuring that it operates with high efficiency while improving the utilization efficiency of the coolant.
