The upper end of the guide rod 33 passes through the inner top of the horizontal plate and is slidably connected. By utilizing the wedge-shaped guide block 32 structure, when the metal pipe moves to the right, the wedge-shaped guide block 32 is first pushed up, and finally the laser cutting head 31 is moved up. In this way, the distance between the laser cutting head 31 and the pipe can be adaptively adjusted to ensure the cutting effect. Furthermore, the figure only shows the effect. In actual use, the right inner wall of the U-shaped plate 12 is at a large distance from the laser cutting head 31, and the subsequently cut metal pipe will be discharged from the blanking port 16.
[0030] As an embodiment of the present invention, a limiting mechanism is further included. The limiting mechanism includes a movable plate 7 arranged above the mounting plate 1. A second motor 17 is installed on the left side of the movable plate 7. The second motor 17 is a dual-axis motor. The right end output shaft of the second motor 17 passes through the movable plate 7 and is fixedly connected to a three-jaw chuck 14. The three-jaw chuck 14 is used to limit the left end of the pipe.
[0031] As an embodiment of the present invention, it also includes a moving mechanism, which is used to move the limiting mechanism. The moving mechanism includes a slide 5 provided at the upper end of the mounting plate 1, and a threaded rod 6 is rotatably connected between the inner walls on the left and right sides of the slide 5. A slider 19 is threadedly connected to the threaded rod 6, and the slider 19 is slidably connected to the inner wall of the slide 5. The upper end of the slider 19 is fixedly connected to a connecting block 20, and the upper end of the connecting block 20 is fixedly connected to the lower end of the moving plate 7. A first motor 8 is installed on the left side of the mounting plate 1, and the output shaft of the first motor 8 extends into the slide 5 and is fixedly connected to the left end of the threaded rod 6.

[0033] As an embodiment of the present invention, it also includes a smoke removal mechanism, which is used to remove the smoke generated during the cutting process. The smoke removal mechanism includes an L-shaped frame 21 fixedly connected to the upper end of the movable plate 7, a piston cylinder 24 is installed at the lower end of the horizontal portion of the L-shaped frame 21, and a piston block 25 that can slide up and down is provided in the piston cylinder 24. The left output shaft of the second motor 17 is fixedly connected to a turntable 22, and a rotating rod 23 is rotatably connected to the left eccentric portion of the turntable 22. The other end of the rotating rod 23 is rotatably connected to the lower end of the piston block 25. The right side of the U-shaped plate 12 is provided with a A filter box 13 is installed, and an activated carbon filter element is arranged inside the filter box 13. The inner bottom of the filter box 13 is connected with the inner space of the U-shaped plate 12 through the connecting pipe 15. The inner bottom of the filter box 13 is connected with the inner top space of the piston cylinder 24 through the one-way tube 27. The inner bottom space of the piston cylinder 24 is connected with the outside world through the one-way port 26. One-way valves are installed inside the one-way tube 27 and the one-way port 26. The one-way valve inside the one-way port 26 flows in a one-way direction so that the piston cylinder 24 discharges the outside world in one direction, and the one-way valve inside the one-way tube 27 flows in a one-way direction so that the filter box 13 enters the piston cylinder 24 in one direction.
[0034] In the present invention, the device is moved to the desired working position via the universal wheel 4 at the lower end of the support plate 3. The left end of the metal pipe to be cut is placed in the three-jaw chuck 14, which is then used to limit and secure the left end of the pipe. The lower end of the right end of the pipe is supported by the arc-shaped groove at the upper end of the support block 10. In the initial state, the laser cutting head 31 is at the appropriate cutting height. When the metal pipe moves to the right, the right end of the pipe first pushes against the wedge-shaped guide block 32 on the left side of the connecting column 30. The wedge-shaped guide block 32 drives the connecting column 30 and the sliding block 29 to slide upward within the sliding cylinder 28. The spring 18 is compressed, which in turn causes the laser cutting head 31 to move upward. This adaptively adjusts the distance between the laser cutting head 31 and the pipe to ensure the cutting effect.
[0035] Start the second motor 17, and its right end output shaft drives the three-jaw chuck 14 to rotate, thereby rotating the pipe. At the same time, start the laser cutting head 31 to cut the pipe. After completing one section of cutting, start the first motor 8, which is a servo motor that can change the rotation direction. Its output shaft drives the threaded rod 6 to rotate in the chute 5. Since the slider 19 is threadedly connected to the threaded rod 6 and is slidably connected to the inner wall of the chute 5, the threaded rod 6 rotates to cause the slider 19 to slide in the chute 5. The slider 19 drives the movable plate 7 and the limit mechanism (including the pipe) to move through the connecting block 20, thereby feeding the pipe and preparing for the next section of cutting. Repeat the above pipe feeding and cutting operations to cut the pipe into multiple sections.
[0036] During the cutting process, the second motor 17 is started, and its left output shaft drives the turntable 22 to rotate. The turntable 22 drives the piston block 25 to slide up and down in the piston cylinder 24 through the rotating rod 23. When the piston block 25 moves downward, a negative pressure is formed in the top space of the piston cylinder 24, and the gas in the filter box 13 (the gas in the filter box 13 is connected to the inner space of the U-shaped plate 12 due to the connecting pipe 15, and the smoke generated by cutting in the U-shaped plate 12 enters the filter box 13 through the connecting pipe 15) is sucked into the piston cylinder 24 through the one-way pipe 27; when the piston block 25 moves upward, the gas in the piston cylinder 24 is discharged to the outside through the one-way port 26. The activated carbon filter element in the filter box 13 can filter and absorb the incoming smoke, removing harmful substances in the smoke and avoiding affecting the surrounding environment.
