A sliding rod 221 is jointly fixedly connected between the secondary plate 219 and the connecting frame 25. A second motor 222 is arranged inside the secondary plate 219. The output end of the second motor 222 is fixedly connected to a threaded rod 223. The front end of the threaded rod 223 is fixedly connected to a first rotating block. The first rotating block is rotatably connected to the connecting frame 25. A push plate 224 is jointly movably connected to the outer sides of the sliding rod 221 and the threaded rod 223. A connecting groove 225 is opened on the inner side of the push plate 224. An extension plate 226 is slidably connected to the inner side of the connecting groove 225. The rear end of the extension plate 226 is fixedly connected to the secondary plate 219.
[0034] Specifically, after the entire pipe is processed according to the cutting dimensions, there will be a part of the pipe with insufficient dimensions remaining. At this time, the second electric push rod 228 will output, pushing the first support plate 229 to support inside the remaining pipe. Then, the second motor 222 will output in the reverse direction, causing the push plate 224 to move the remaining pipe towards the secondary plate 219. When the extension plate 226 is inserted into the connection groove 225, the first support plate 229 will contract, 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 into the first collection groove 220.
[0035] In this embodiment, a first fixing rod 227 is fixedly connected to the front end of the push plate 224. The lower end of the extension plate 226 is attached to the surface of the first fixing rod 227. A plurality of second electric push rods 228 are installed on the outer side of the first fixing rod 227. The output end of the second electric push rod 228 is fixedly connected to a first support plate 229. A plurality of first support plates 229 jointly support the inner wall of the pipe. A base three 230 is fixedly connected to one side of the base two 213. An installation plate one 231 is fixedly connected to the upper end of the base three 230. A first cylinder 232 is installed on the other side of the installation plate one 231. The output end of the first cylinder 232 is fixedly connected to a material pushing groove 233. A baffle 234 is fixedly connected to one side of the material pushing groove 233. An installation plate two 235 is fixedly connected to the upper end of the installation plate one 231.

One end of the inlet plate 237 is fixedly connected to the support groove 215.
[0036] Specifically, when the staff sequentially place the pipes to be cut into uniform-sized paragraphs into the storage groove 236, the first pipe placed in the storage groove 236 will directly enter the material pushing groove 233 first. Then, an intermittent output instruction is set for the first cylinder 232, and the first cylinder 232 is started to output. At this time, under the connection of the first cylinder 232, the material pushing groove 233 is pushed towards the inlet plate 237. When the material pushing groove 233 drives the first group of pipes to be cut to move above the inlet plate 237, the baffle 234 will move to the lower end of the storage groove 236 to block the next group of pipes. At this time, the pipes in the material pushing groove 233 will roll onto the inlet plate 237 and then roll into the support groove 215 through the inlet plate 237.
[0037] In this embodiment, the transfer mechanism 3 includes a fourth base 31. The rear end of the fourth base 31 is fixedly connected to the first base 21. A second collection trough 32 is slidably connected to the upper end of the fourth base 31. A second cylinder 33 is installed at the upper end of the fourth base 31. The output end of the second cylinder 33 is fixedly connected to the second collection trough 32. A rubber pad 34 and a ramp 35 are arranged inside the second collection trough 32. A support platform 36 is fixedly connected to the rear end of the second collection trough 32. Two sets of pulleys 37 are movably connected to the upper end of the support platform 36. A conveyor belt 38 is movably connected to the outside of the two sets of pulleys 37. Multiple connection components 39 are arranged on the outside of the conveyor belt 38.
[0038] Specifically, the provided second collection trough 32 is used to collect the cut pipes. With the rubber pad 34 and the ramp 35 arranged inside it, the cut pipes can be effectively collected and protected. And by providing the second cylinder 33, the distance between the connection component 39 and the pipe cutting machine main body 1 can be changed, so as to be applicable to cutting pipes of different lengths.
[0039] In this embodiment, the connection component 39 includes a second grinding disc 391. A connection block 392 is fixedly connected to the front end of the second grinding disc 391. The connection block 392 is rotatably connected to the conveyor belt 38. A second toothed ring 393 is rotatably connected to the outside of the second grinding disc 391. A second fixing rod 394 is fixedly connected to the rear end of the second grinding disc 391. Multiple third electric push rods 395 are installed on the outside of the second fixing rod 394. The output end of the third electric push rod 395 is fixedly connected to a second support plate 396. The multiple second support plates 396 jointly support the inner wall of the pipe.
[0040] Specifically, the second support plate 396 will enter the inside of the pipe from the front end of the pipe and support it inside the pipe under the output of the third electric push rod 395. Thus, when the pipe cutting machine main body 1 cuts the pipe, the pipe can be kept stable while rotating, making the cutting more accurate, and the pipe can be prevented from directly falling and being knocked after cutting.
[0041] In this embodiment, a third motor 310 is arranged at the lower end of one of the two sets of pulleys 37. The third motor 310 is installed inside the support platform 36. A second rotating block is fixedly connected to the lower end of the other set of the two sets of pulleys 37. The second rotating block is rotatably connected to the support platform 36. An inclined plate one 311 and an inclined plate two 312 are fixedly connected to the upper end of the support platform 36. The inclined plate one 311 and the inclined plate two 312 are jointly located in front of the second grinding disc 391. A fixing block 313 is fixedly connected to the upper end of the support platform 36. A third rotating block is rotatably connected to the inside of the fixing block 313. The front end of the third rotating block passes through the fixing block 313 and is fixedly connected to a second tooth column 314. The second tooth column 314 meshes with the second toothed ring 393. The rear end of the third rotating block passes through the fixing block 313 and is fixedly connected to the clamping rod 24.
[0042] Specifically, start the third motor 310 and set an intermittent command for it. Under the intermittent rotation of the belt pulley 37, the conveyor belt 38 starts to move with the cut pipes. When the cut pipes move to a position close to the first inclined plate 311 along with the conveyor belt 38, the third electric push rod 395 will contract, and then there will be a gap between the cut pipes and the second grinding disc 391. Then, the first inclined plate 311 will enter between the pipes and the second grinding disc 391. During the movement along with the conveyor belt 38, due to the inclined setting of the second inclined plate 312, the pipes will gradually move away from the second grinding disc 391 and fall into the second collection trough 32.
[0043] During use, an intermittent cutting instruction is set for the pipe cutting machine main body 1. Then, the staff sequentially place the pipes to be cut into uniformly sized segments into the storage tank 236. The first pipe placed in the storage tank 236 will directly enter the pushing trough 233 first. Then, an intermittent output instruction is set for the first cylinder 232, and the first cylinder 232 is started to output. At this time, under the connection of the first cylinder 232, the pushing trough 233 is pushed towards the feeding plate 237. When the pushing trough 233 moves the first group of pipes to be cut above the feeding plate 237, the baffle 234 will move to the lower end of the storage tank 236 to block the next group of pipes. At this time, the pipes in the pushing trough 233 will roll onto the feeding plate 237 and then roll through the feeding plate 237 into the supporting trough 215. Then, the first cylinder 232 contracts, and the pushing trough 233 returns to the lower end of the storage tank 236 again, and the next group of pipes to be cut will fall into the pushing trough 233. After the first group of pipes to be cut arrives in the supporting trough 215, the second motor 222 is started at this time to make the threaded rod 223 rotate. Through the screw principle, the push plate 224 starts to move towards the pipe, and the first supporting plate 229 enters the inner side of the rear end of the pipe. As the second motor 222 rotates and outputs, the push plate 224 pushes the rear end of the pipe, making the pipe move towards the conveyor belt 38. During this process, the pipe will enter the inner side of the first toothed ring 28. When the front end of the pipe abuts against the second grinding disc 391, the push plate 224 stops pushing the pipe to move. At this time, multiple groups of second supporting plates 396 have entered the inner side of the pipe from the front end of the pipe. Then, the first electric push rod 210 and the third electric push rod 395 are started simultaneously to clamp the outer side of the pipe with multiple groups of outer clamping plates 211. Multiple groups of second supporting plates 396 support the inner side of the pipe. Then, the first motor 217 is started and an intermittent instruction is set for it, making the first toothed column 22 rotate. Through the meshing of the first toothed ring 28 and the first toothed column 22, multiple groups of outer clamping plates 211 are made to clamp the pipe and rotate together. And when the first toothed column 22 rotates, through the connection of the clamping rod 24, the second toothed column 314 rotates simultaneously. Under the action of the meshing second toothed ring 393, multiple groups of second supporting plates 396 can rotate along with the pipe. When the pipe rotates, the pipe cutting machine main body 1 starts to laser cut the pipe. After the cutting is completed, the first motor 217 stops output. Supported by the second supporting plates 396, the cut pipe will not fall. Then, the third motor 310 is started and an intermittent instruction is set for it. Under the intermittent rotation of the belt pulley 37, the conveyor belt 38 starts to move the cut pipe. When passing through the first grinding disc 212 during the moving process, the cutting edge of the pipe will be ground. Then, when the next group of second toothed rings 393 moves to mesh with the second toothed column 314, the conveyor belt 38 will stop rotating. Then, the first electric push rod 210 contracts, and the push plate 224 continues to push the pipe towards the conveyor belt 38 and then the above operations are continued. When the cut pipe moves to a position close to the inclined plate 311 along with the movement of the conveyor belt 38, the third electric push rod 395 will contract.Then, there will be a gap between the cut pipe and the second grinding disc 391. Next, the first inclined plate 311 will enter between the pipe and the second grinding disc 391. During the movement along the conveyor belt 38, due to the inclined setting of the second inclined plate 312, the pipe will gradually move away from the second grinding disc 391 and fall into the second collection trough 32. However, after the whole pipe is processed according to the cutting size, there will be a part of the pipe with insufficient size remaining. At this time, the second electric push rod 228 will output and push the first support plate 229 to support the inside of the remaining pipe. Then, the second motor 222 will output in the reverse direction, making the push plate 224 drive the remaining pipe to move towards the auxiliary plate 219. When the extension plate 226 is inserted into the connection groove 225, the first support plate 229 will contract, 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 into the first collection trough 220.
