[0030] In the embodiment, one end of plastic pipeline is installed on driving chuck assembly 3, and the middle and tail of the pipeline are installed on driven chuck assembly 4, when the pipeline moves to the set position, the pipeline is cut off by cutting mechanism 2.

[0031] Further, please refer to the attached Figure 3The cutting mechanism 2 includes a laser module 21, which is located above the pipe; a laser cutting head 22, which is fixed to the lower end of the laser module 21; a laser module base plate 23, on which the laser module 21 is fixed; a Y-axis movable plate 24, which is connected to the laser module base plate 23 via a ball screw and is used to drive the laser module 21 to move up and down; an X-axis adjusting base 25, on which the Y-axis movable plate 24 is movably connected and can move horizontally along the X-axis adjusting base 25; and a vertical fixing frame 26, which is fixedly connected to the side of the frame 1, and the X-axis adjusting base 25 is fixedly connected to the vertical fixing frame 26.

[0032] In this embodiment, the laser emitted by the laser module 21 illuminates the outer surface of the pipe through the laser cutting head 22, which is located above the vertical center of the pipe. By controlling the positions of the Y-axis movable plate 24 and the X-axis adjusting base 25, the laser focus can be concentrated on the highest point of the pipe. The pipe rotates one revolution under the drive of the active chuck assembly 3 and the driven chuck assembly 4, enabling the laser to quickly cut the pipe and achieve the goal of efficient cutting.

[0033] For further details, please refer to the appendix. Figure 4 The active chuck assembly 3 includes an active chuck mounting base 31 slidably connected to the slide rail 5, an active chuck motor 32 mounted on one side of the active chuck mounting base 31, an active chuck 33 mounted on the active chuck mounting base 31, and an active chuck linear module 34 for driving the active chuck mounting base 31 to move horizontally. The active chuck motor 32 is connected to one end of the active chuck 33 by a belt and is used to drive the active chuck 33 to rotate relative to the active chuck mounting base 31.

The active chuck 33 clamps the inner diameter of the pipe, and driven by the active chuck motor 32, the active chuck 33 drives the pipe to rotate, effectively avoiding the phenomenon of prying due to the external center of gravity.

The driven gear 43 drives the clamping and positioning mechanism 44 to clamp the pipe and drive the pipe to rotate. The driven chuck linear module 45 is mounted on the side of the frame 1.

[0036] In this embodiment, the positions of the two driven chuck mounting seats 41 on the slide rail can be precisely adjusted by the driven chuck linear module 45.

By clamping the pipe with the two driven chuck assemblies 4 arranged in parallel, the pipe is firmly clamped and precisely positioned, and the pipe also has sufficient stability when being processed and cut. Combined with the laser module 21 for precise cutting, true zero-tail cutting is achieved.

[0037] For further details, please refer to the appendix. Figure 5 The clamping and positioning mechanism 44 includes an annular fixed base 46 fixed on the driven chuck fixed seat 41 and coaxially arranged with the driven gear 43, and several support arms 47 installed on the annular fixed base 46 for clamping the pipe. The driven gear 43 is fixedly connected to the annular fixed base 46 and is used to drive the annular fixed base 46 to rotate.

[0038] In this embodiment, the support arms 47 are symmetrically arranged along the four directions of the outer surface of the pipe for clamping the pipe in four directions. The eight support arms 47 form two parallel planes, which can ensure that the pipe is well clamped and effectively avoid the phenomenon of prying due to the external center of gravity.

[0039] Furthermore, there are eight support arms 47, which are arranged in an array along the outer diameter of the pipe. Each support arm 47 is equipped with an elastic roller 48, the surface of which contacts the outer surface of the pipe to press against the outer wall of the pipe.
