During the feeding process, the two groups of rotating rollers 603 are driven to rotate by the motor 602, one group of rotating rollers 603 rotates clockwise, and the other group of rotating rollers 603 rotates counterclockwise, and the friction with the pipe is increased by the rubber layer 604, so that the metal pipe can be automatically and slowly pushed to the laser cutting area at a consistent speed, making the cutting process more controllable, and the movement speed is controlled by adjusting the rotation speed of the rotating rollers 603 to maintain the uniform flatness and smoothness of the cutting surface.
[0027] Example 2
[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:
[0029] As a preferred embodiment, a mounting plate 7 is provided on the left side of the upper end surface of the workbench 1, and six groups of mounting plates 7 are provided, and the positions of every two groups of mounting plates 7 correspond to each other; further, every two groups of mounting plates 7 correspond to each other, so that the six groups of elastic clamping components 8 are respectively combined into three groups of clamping structures, and the three groups of clamping structures all clamp the metal pipe on the same central axis, thereby matching the clamping length.
[0030] As a preferred embodiment, an elastic clamping assembly 8 is provided on one side of the opposite surface of each two groups of mounting plates 7. The elastic clamping assembly 8 includes a telescopic rod 801, which is provided at the center of one side of the mounting plate 7.

Each two groups of feeding assemblies 6 are mirror-imaged, and each two groups of feeding assemblies 6 form a clamping structure; further, the two semicircular clamping plates 803 of the two groups of elastic clamping assemblies 8 clamp the pipeline through mirror-image correspondence, and then the reaction force of the spring 802 makes the telescopic rod 801 have resilience. When the two groups of clamping plates 803 abut against each other and clamp the metal pipeline, the adaptive pipe diameter can intelligently adapt to the different diameters of the pipeline and will not firmly clamp the pipeline, which is convenient for laser cutting.
[0031] As a preferred embodiment, a material guide trough 3 is provided on the upper end surface of the material guide platform 2, and the surface of the material guide trough 3 is arc-shaped; further, the material guide trough 3 guides and supports the metal pipes delivered by the two groups of feeding components 6 to avoid the metal pipes being suspended in the air, and the arc-shaped surface facilitates the material guide trough 3 to adapt to the metal round pipes.
