At this time, under the meshing cooperation of the linkage gear ring 110 and the reciprocating gear plate 103, the moving plate 104 slides to the right along the ladder-shaped slide 102. When the moving cover 202 is separated from the fixed cover 201, the moving cover 202 pops out to the right under the action of the return spring 213.

[0024] In this embodiment, when the threaded rod 111 moves outward, the threaded barrel 109 rotates clockwise, and the moving plate 104 slides to the right along the ladder-shaped slide groove 102 under the meshing cooperation of the linkage gear ring 110 and the reciprocating gear plate 103. When the threaded rod 111 moves inward, the threaded barrel 109 rotates counterclockwise, and the moving plate 104 slides to the left along the ladder-shaped slide groove 102 under the meshing cooperation of the linkage gear ring 110 and the reciprocating gear plate 103.

[0026] In this embodiment, a reciprocating motor 114 is designed to drive the threaded rod 111 to reciprocate relative to the threaded barrel 109, thereby driving the threaded barrel 109 to intermittently move clockwise and counterclockwise.

[0027] See attached Figure 6 -Attached Figure 8 A fan 309 is installed on the vertical frame 308, and a switch 117 cooperating with the moving plate 104 is also provided on the inner wall of the ladder-shaped slide 102.

[0028] In this embodiment, when the moving plate 104 drives the clamping mechanism 105 to slide to the right, the outer gear 306 rotates inward under the drive of the linkage rack 303, and the linkage rack 307 and the nozzle 310 slide inward. When the inner wall of the moving plate 104 presses the switch 117, the fan 309 is started, and the fan 309 cleans the fixed cover 201 and the moving cover 202 on both sides through the nozzle 310.

[0029] See attached Figure 1 -Attached Figure 3 A material discharge cavity 118 is provided on the workbench 101 and is located inside the fixed cover 201 and the moving cover 202 . A cutting slide 119 is provided below the material discharge cavity 118 . A plurality of slag discharge holes 120 are provided on the cutting slide 119 . A slag collecting box 121 is also provided below the cutting slide 119 .

[0030] In this embodiment: after the cutting is completed, the waste pipe after the pipe 106 is cut enters the next processing step through the cutting slide 119. After the blowing mechanism 3 cleans the fixed cover 201 and the moving cover 202 on both sides, the slag generated by the cutting will also fall into the slag collecting box 121 below through the slag discharge hole 120.

A notch 204 cooperating with the track 203 is provided on the top of the moving cover 202 . A socket 208 cooperating with the pipe 106 is provided on the side of the moving cover 202 .

When the clamping mechanism 105 clamps the pipe 106 and moves toward the position of the laser gun 206, a socket 208 is designed to allow the pipe 106 to pass through the moving cover 202.

[0034] In this embodiment, when the moving cover 202 moves toward the fixed cover 201 and presses against it, the slide bar 211 moves to the left, and the moving cover 202 and the fixed cover 201 abut against each other and form a cutting cavity. When the moving plate 104 is separated from the moving cover 202, the moving cover 202 is ejected and slides to the right under the action of the return spring 213. At this time, the blowing mechanism 3 slides inward, and a movement space is provided between the moving cover 202 and the fixed cover 201 for the blowing mechanism 3.

[0035] See attached Figure 3 and attached Figure 5 A vertical plate 124 is provided in the middle of the moving plate 104, a rotating cylinder 125 is movably provided inside the vertical plate 124, a rotating ring gear 127 is fixedly provided on the outer side of the rotating cylinder 125, a symmetrical horizontal plate 128 is fixedly provided on the outer side of the rotating ring gear 127, a clamping cylinder 129 is installed on the horizontal plate 128, and a clamping plate 130 cooperating with the pipeline 106 is provided at the output end of the clamping cylinder 129.

[0036] In this embodiment, a clamping cylinder 129 is designed to clamp the pipe 106 and allow it to be cut as the moving plate 104 extends into the fixed cover 201 and the moving cover 202.

[0037] See attached Figure 3 and attached Figure 5 A rotating motor 131 is also installed on the moving plate 104 , and a driving gear 132 meshing with the rotating ring gear 127 is installed at the output end of the rotating motor 131 .

[0038] In this embodiment, a rotating motor 131 is designed to drive the rotating drum 125 and the rotating gear ring 127 to rotate so as to perform 360-degree cutting on the pipe 106 .

[0039] See attached Figure 3 and attached Fig. 9 -Attached Fig.10 A control panel 133 is also provided on the workbench 101 , a symmetrical sliding cavity 123 is also opened on the workbench 101 , a sliding block 209 cooperating with the sliding cavity 123 is provided at the bottom of the moving cover 202 ; a convex ring 126 is also provided on the outer wall of the rotating cylinder 125 .

A slider 209 is designed to further improve the stability of the moving cover 202 when it slides under the drive of the moving plate 104. When the rotating cylinder 125 rotates relative to the vertical plate 124, a convex ring 126 is designed to install it and improve the stability during rotation.

[0041] Working principle of the present invention: When the device is used, firstly, the pipe 106 to be cut is placed into the rotating cylinder 125, and then the clamping cylinder 129 is started to clamp the pipe 106. Then the reciprocating motor 114 is started through the control panel 133, and the reciprocating motor 114 drives the threaded rod 111 to reciprocate relative to the threaded cylinder 109 through the swing arm 115 and the linkage arm 116. When the threaded rod 111 moves inward, the threaded cylinder 109 rotates counterclockwise. At this time, under the meshing cooperation of the linkage gear ring 110 and the reciprocating gear plate 103, the moving plate 104 slides to the left along the ladder-shaped slide groove 102. Under the push of the moving plate 104, the moving cover 202 moves toward the fixed cover 201, and the sliding rod 211 moves to the left. At this time, the moving cover 202 and the fixed cover 201 abut and form a cutting cavity. Finally, the position of the gun seat 205 is adjusted according to the needs, and then the laser gun 206 and the rotating motor 131 are started to cut the pipe 106 360 degrees. When the cutting is completed, the waste pipe after the pipe 106 is cut enters the next processing step through the cutting slide 119. When the threaded rod 111 moves outward, the threaded barrel 109 rotates clockwise. At this time, under the meshing cooperation of the linkage gear ring 110 and the reciprocating tooth plate 103, the moving plate 104 slides to the right along the ladder-shaped slide 102. When the moving cover 202 is separated from the fixed cover 201, the moving cover 202 pops out to the right under the action of the reset spring 213. When the moving plate 104 drives the clamping mechanism 105 to slide to the left, under the drive of the linkage rack 303, the outer gear 306 will rotate outward, and the linkage tooth plate 307 and the nozzle 310 will slide outward. When the moving plate 104 drives the clamping mechanism 105 to slide to the right, under the drive of the linkage rack 303, the outer gear 306 will rotate inward, and the linkage tooth plate 307 and the nozzle 310 will slide inward. When the inner wall of the moving plate 104 squeezes the switch 117, the fan 309 is started. At this time, the fan 309 cleans the fixed cover 201 and the moving cover 202 on both sides through the nozzle 310, and the slag produced by the cutting falls into the slag collecting box 121 below through the slag discharge hole 120.
