The frame 11 is provided with a third adjusting assembly 84, the third adjusting assembly 84 comprises a rotating screw 832 rotatably connected in the chute, and the rotating screw 832 passes through the adjusting block 81 and is in threaded connection with the adjusting block 81; a fifth motor 841 is fixedly connected to the frame 11, and an output shaft of the fifth motor 841 is connected to one end of the rotary screw 832.

Starting the fifth motor 841, driving the rotating screw 832 to rotate by the output shaft of the fifth motor 841, driving the adjusting block 81 to slide in the chute by the rotating screw 832, driving the lantern ring 83 to move by the adjusting rod 82 on the adjusting block 81, and combing the first recycling pipe 681 by the lantern ring 83; when the case 12 moves toward the discharging end of the housing 11, the collar 83 is moved to the middle of the first recovery pipe 681, so that when the case 12 moves the first recovery pipe 681, the first recovery pipe 681 is folded with respect to the collar 83, thereby reducing the phenomenon that the first recovery pipe 681 is twisted together.

The implementation principle of the pipe cutting equipment in the embodiment of the application is as follows: the position of the adjusting screw 592 relative to the fixing block 56 is adjusted according to the position of the tube, and then the position of the adjusting screw 592 is fixed by the adjusting nut 593.

The pipe to be cut is placed on the frame 11, one end of the pipe sequentially penetrates through the feeding hole, the processing cavity 121 and the discharging hole, and the pipe is pushed to move by the tractor.

When the tube moves to a certain position of the frame 11, the first motor 321 is started to make the first conveyor belt 31 drive the box 12 to move.

When the moving speed of the box 12 is the same as the moving speed of the pipe, the second hydraulic cylinder 242 is activated to make the abutting block 23 abut against the peripheral side wall of the pipe.

Then, the third motor 581, the first hydraulic cylinder 57 and the second motor 431 are started, and the third motor 581 drives the cutting knife 54 to rotate; a piston rod of the first hydraulic cylinder 57 drives the connecting frame 52 to move, and a driving shaft 53 on the connecting frame 52 drives the cutting knife 54 to move, so that the cutting knife 54 can cut the pipe; the second motor 431 can enable the rotating block 41 to rotate, the rotating block 41 drives the connecting shaft 51 and the fixed shaft 55 to rotate, and the connecting frame 52 on the connecting shaft 51 drives the cutting knife 54 to move; therefore, when cutting the pipe, the cutting knife 54 not only rotates, but also revolves under the driving of the rotating block 41, so that the pipe can be better cut off. And the tubing and housing 12 remain in motion while the cutter 54 is cutting the tubing. After the pipe is cut, the pipe can keep moving, and the cutting knife 54 is returned to the original position through the second motor 431 and the first hydraulic cylinder 57; the first motor 321 is activated to return the housing 12 to the original position of the frame 11.

When the cutting knife 54 cuts the pipe, the negative pressure pump is started, and the scraps generated when the cutting knife 54 cuts the pipe are collected in the collection box. When the rotating block 41 rotates, the first connecting pipe 63 drives the third connecting pipe 67 to rotate, and the third connecting pipe 67 between the first connecting pipe 63 and the second adjusting block 72 moves towards the direction close to the second adjusting block 72, so that the whole third connecting pipe 67 is wound on the side wall of the accommodating groove 412. When the cutting is completed, when the rotating block 41 rotates to return the cutting knife 54 to the initial position, the first connecting pipe 63 drives the third connecting block 61 to rotate, the fourth motor 741 is started, the output shaft of the fourth motor 741 drives the third gear 742 to rotate, because the third gear 742 is meshed with the annular rack 743, when the third gear 742 rotates, the first adjusting block 71 can slide in the annular groove 413, the adjusting rod 73 on the first adjusting block 71 drives the second adjusting block 72 to move, the second adjusting block 72 drives the middle position of the third connecting pipe 67 to move, so that the third connecting pipe 67 is kept in a tensioned state, and the phenomenon that the third connecting pipe 67 is wound together is reduced. When the box 12 moves, the fifth motor 841 is started to make the collar 83 comb the first recycling pipe 681, thereby reducing the phenomenon that the first recycling pipe 681 is twisted together.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
