[0029] Specifically, the second support plate 396 will enter the inner side of the pipe from the front end thereof, and support the inner side of the pipe under the output of the third electric push rod 395, so that when the pipe cutting machine body 1 cuts the pipe, the pipe can be rotated while keeping it stable, making the cutting more accurate and avoiding the pipe from falling and bumping directly after cutting.

[0030] In this embodiment, a third motor 310 is provided at the lower end of one of the two groups of pulleys 37, and the third motor 310 is installed on the inner side of the support platform 36. The lower end of the other group of the two groups of pulleys 37 is fixedly connected with a rotating block 2, and the rotating block 2 is rotatably connected to the support platform 36. The upper end of the support platform 36 is fixedly connected with an inclined plate 1 311 and an inclined plate 2 312, and the inclined plate 1 311 and the inclined plate 2 312 are jointly located at the front end of the second grinding disk 391.

The rear end of the rotating block 3 is fixedly connected with the clamping rod 24 through the fixed block 313.

[0031] Specifically, the third motor 310 is started and an intermittent instruction is set for it. Under the intermittent rotation of the pulley 37, the conveyor belt 38 begins to move with the cut pipe. When the cut pipe moves with the conveyor belt 38 to a position close to the inclined plate 1 311, the third electric push rod 395 will shrink, and then there will be a gap between the cut pipe and the second grinding disc 391. Then the inclined plate 1 311 will enter between the pipe and the second grinding disc 391. In the process of moving with the conveyor belt 38, through the inclined setting of the inclined plate 2 312, the pipe will gradually move away from the second grinding disc 391 and fall into the collecting trough 2 32.

[0032] When in use, an intermittent cutting instruction is set for the pipe cutting machine body 1, and then the staff will place the pipes to be cut into sections of uniform size into the storage trough 236 in sequence. The first pipe placed in the storage trough 236 will directly enter the push trough 233 first, and then an intermittent output instruction is set for the first cylinder 232, and the first cylinder 232 output is started. At this time, the push trough 233 is pushed to move in the direction of the feed plate 237 under the connection of the first cylinder 232. When the push trough 233 moves to the top of the feed plate 237 with the first group of pipes to be cut, the baffle 234 will move to the lower end of the storage trough 236 to block the next group of pipes. At this time, the pipes in the push trough 233 will roll onto the feed plate 237 and roll down through the feed plate 237 When the first group of pipes to be cut enters the bracket 215, the first cylinder 232 contracts, and the pushing groove 233 returns to the lower end of the storage groove 236. The next group of pipes to be cut fall into the pushing groove 233. After the first group of pipes to be cut enters the bracket 215, the second motor 222 is started to rotate the threaded rod 223. Through the screw principle, the push plate 224 begins to move toward the direction of the pipe, and the first support plate 229 enters the inner side of the rear end of the pipe. With the rotation output of the second motor 222, the push plate 224 pushes the rear end of the pipe to move the pipe toward the direction of the conveyor belt 38. During the process, the pipe will enter the inner side of the gear ring 28. When the front end of the pipe hits the second grinding disc 391, the push plate 224 stops pushing the pipe to move. At this time, multiple groups of second support plates 229 are The plate 396 has entered the inner side of the pipe from the front end, and then the first electric push rod 210 and the third electric push rod 395 are started at the same time, so that the multiple groups of outer clamping plates 211 clamp the outer side of the pipe, and the multiple groups of second support plates 396 are supported on the inner side of the pipe. Then the first motor 217 is started and an intermittent instruction is set for it, so that the first tooth column 22 rotates, and the tooth ring 1 28 engages with the first tooth column 22, so that the multiple groups of outer clamping plates 211 clamp the pipe and rotate together, and when the first tooth column 22 rotates, the second tooth column 314 rotates at the same time through the connection of the clamping rod 24, and under the action of the meshing tooth ring 2 393, the multiple groups of second support plates 396 can rotate with the pipe. When the pipe rotates, the pipe cutting machine body 1 starts to laser cut the pipe. After the cutting is completed, The first motor 217 stops outputting. With the support of the second support plate 396, the cut pipe will not fall. Then the third motor 310 is started and an intermittent command is set for it. Under the intermittent rotation of the pulley 37, the conveyor belt 38 starts to move with the cut pipe. When passing through the first grinding disc 212 during the movement, the cut edge of the pipe is polished. Then when the next set of gear rings 393 moves to mesh with the second gear column 314, the conveyor belt 38 stops rotating. Then the first electric push rod 210 contracts, and the push plate 224 continues to push the pipe to move toward the conveyor belt 38. Then the above operation is performed. When the cut pipe moves to a position close to the inclined plate 1 311 as the conveyor belt 38 moves, the third electric push rod 395 contracts.Then, there will be a gap between the cut pipe and the second grinding disc 391, and then the inclined plate 1 311 will enter between the pipe and the second grinding disc 391. In the process of moving with the conveyor belt 38, the pipe will gradually move away from the second grinding disc 391 and fall into the collecting tank 2 32 through the inclined setting of the inclined plate 2 312. However, after the whole pipe is processed according to the cutting size, a part of the pipe of insufficient size will remain. At this time, the second electric push rod 228 will output, push the first support plate 229 to support the inner side of the remaining pipe, and then the second motor 222 will output in the reverse direction, so that the push plate 224 moves with the remaining pipe toward the auxiliary plate 219, and when the extension plate 226 is inserted into the connecting groove 225, the first support plate 229 will shrink, and under the action of the extension plate 226, the remaining pipe will be pushed off the first support plate 229, and the remaining pipe will be collected in the collecting tank 1 220.
