[0048] As shown in the drawings, Figures 10-14 The pipe cutting mechanism comprises a bottom plate 401 and a cutter holder 406. The bottom plate 401 is slidingly installed on a sliding rail 402, and the sliding rail 402 is fixedly installed on the station table 2. The side of the bottom plate 401 is fixedly connected with a connecting plate 403. The connecting plate 403 is threadedly connected with a lead screw 404 in the middle. The end portion of the lead screw 404 penetrates through a bearing seat and is fixedly installed with a rotating handle 405. The cutter holder 406 is movably connected with a driving wheel 407 and a driven wheel 419 through bearings respectively. The driving wheel 407 and the driven wheel 419 are drivingly connected through a transmission belt. The driven wheel 419 is fixedly installed with a blade 418. The driving wheel 407 is sleeved in a hexagonal rod 408 through a hexagonal hole. The hexagonal rod 408 is installed on the vertical plate 9 and the feeding plate 10 through rotating bearings respectively. One end of the hexagonal rod 408 is drivingly connected with a cutting motor 409. The cutter holder 406 is fixedly installed on a sliding block 410, which is slidingly connected with a guide rail 411. The guide rail 411 is fixedly installed on the bottom plate 401.

[0049] As shown in the drawings, Figure 16As shown, the out-pipe mechanism includes a second rodless air cylinder 501 fixedly installed on a bottom plate 502, the second rodless air cylinder 501 is arranged in parallel with the pipe shaft 20, the bottom plate 502 is fixedly installed on the vertical plate 9 and the feeding plate 10 at both ends through connecting plates respectively, a connecting plate 507 is slidably connected on the second rodless air cylinder 501, a telescopic air cylinder 503 is fixedly installed on the connecting plate 507, an out-feeding push block 506 is connected to the telescopic end of the telescopic air cylinder 503, and the out-feeding push block 506 is in contact with the pipe shaft 20.

[0050] When the driving end of the rotating disc motor 11 drives the rotating disc 12 to rotate the original in-pipe work station 13 to the pipe cutting work station 14, first, the first air cylinder 301 is opened, the telescopic end of the first air cylinder 301 drives the telescopic shaft 305 to move, then the telescopic shaft 305 drives the top block 307 to be in contact with the pipe shaft 20, the module sliding table 303 is controlled to work, the sliding end of the module sliding table 303 drives the alignment sleeve 306 to push the paper tube on the pipe shaft 20 forward, in this embodiment, a cursor sensor 320 can be arranged near the alignment sleeve 306, when the sensing end of the cursor sensor 320 senses the cursor on the paper tube, the module sliding table 303 can be controlled to stop moving by the control circuit, that is, the paper tube reaches the correct position; the telescopic end of the second air cylinder 302 is controlled to push the conical block 311, then the second connecting rod 312 is driven to move downward along the guide rail sliding block 317 through the inclined surface of the conical block 311 and press the linear spring 319, so as to drive the clamp head 313 to clamp the paper tube, then the motor 304 drives the second gear 309 to rotate, then the first gear 308 drives the paper tube to rotate, when the paper tube rotates, the rotating sleeve 310 rotates, and the pipe shaft 20 does not rotate; the cutter mechanism starts to cut the pipe immediately.

[0051] Before cutting the pipe, the handle 405 can be rotated to drive the entire bottom plate 401 and the cutter holder to move forward and backward on the sliding rail 402 to adapt to different diameters of products. When the pipe diameter is small, the cutter holder needs to move to the direction close to the rotating disc 12, and when the pipe diameter increases, the cutter holder moves to the direction away from the rotating disc 12. The cutter holder 406 is controlled to slide on the guide rail 411 to adjust the position of the cutter holder 406 to adapt to the different length requirements of the paper tube; when cutting, the cutting motor 409 drives the hexagonal rod 408 to rotate, and since the hexagonal rod 408 is connected with the driving wheel 407 through the hexagonal hole, the driving wheel 407 is driven to rotate through the hexagonal rod 408, then the driving wheel 407 drives the driven wheel 419 to rotate, and then the blade 418 on the driven wheel 419 rotates to cut. When the blade 418 rotates, the cutting speed is fast, the cut is neat and has no burr, but the cutting tool wears out quickly.

[0052] In this embodiment, as shown in Figure 17As shown, the blade 418 can also be directly installed at the end of the tool holder 406. In the pipe cutting process, the blade 418 is fixed and does not rotate, and when the paper tube rotates, the paper tube rubs against the cutter to cut the paper tube. This method can make the cutter less likely to wear, but the cutting speed is slower. In the above two schemes, the user can choose according to his own needs.

[0053] After cutting is completed, the extension end of the second cylinder 302 is controlled to retract the tapered block 311, the second connecting rod 312 slides upward under the elastic action of the linear spring 319, and the chuck 313 is opened; and the module sliding table 302 of the alignment mechanism is controlled to retract the alignment sleeve 306, and the first cylinder 301 is controlled to move the extension shaft 305 to the original position. Wait for the next alignment and cutting of the pipe.

[0054] The driving end of the turntable motor 11 drives the turntable 12 to rotate, so that the original pipe cutting station 14 rotates to the pipe discharging station 15. The sliding seat is driven to move by controlling the second rodless cylinder 501, and then the extension cylinder 503 is driven to move to a position close to the turntable 12. The extension end of the extension cylinder 503 is controlled to drive the discharging block 506 to contact the pipe shaft 20, and then the sliding seat is driven to move by controlling the second rodless cylinder 501, so as to drive the discharging block 506 to move to the discharging port 16, so that the paper tube on the pipe shaft 20 can be pushed out.

[0055] In the embodiment, the side plate 101 is arranged on the side of the pipe storage bin 3, the side plate 101 is connected with the fixed plate 103 through the light shaft 102, the linear bearing 104 is installed on the fixed plate 103, one end of the light shaft 102 is fixedly connected with the side plate 101, and the other end of the light shaft 102 penetrates through the linear bearing 104 and is installed with a limiting piece. Therefore, when the paper tube is placed in the pipe storage bin 3, the position of the side plate 101 can be pulled according to the paper tubes of different lengths through the sliding action of the light shaft 102 in the linear bearing 104, so that the width of the pipe storage bin 3 can be adjusted to adapt to paper tubes of different lengths.

[0056] In the embodiment, the tool rest 406 is provided with six groups, and each tool rest 406 is provided with a positioning pin hole, and a locking pin is arranged in the positioning pin hole, the locking pin is in contact with the guide rail 411, and the tool rest 406 is provided with a module 415 on the side, the module 415 is provided with a positioner 416 which is slidingly installed on the module 415, and the positioner 416 is matched with the positioning pin hole. The six groups of tool rests 406 are used to cut the pipe at the same time, so as to improve the work efficiency, and when the six groups of tool rests 406 are fixed, the module 415 drives the positioner 416 to move, when the positioner 416 reaches the required position, the telescopic end of the positioner 416 is matched with the positioning pin hole, so as to lock the locking pin in the tool rest 406, and then the position of the tool rest 406 is fixed. The telescopic end of the positioner 416 is retracted, and the position of the next tool rest 406 is locked by the movement of the module 415. And because the movement of the module 415 can be numerically controlled, the distance between the tool rests 406 can be numerically controlled according to the length of the paper tube.

[0057] In the embodiment, the telescopic end of the telescopic cylinder 503 is fixedly provided with a connecting block 504, the connecting block 504 is fixedly connected with a buffer spring 505 between the connecting block 504 and the discharging block 506; the connecting block 504 is fixedly provided with a sliding rail 508 below, and the connecting plate 507 is fixedly provided with a sliding block 509, and the sliding rail 508 is slidingly connected with the sliding block 509.
