The three positioning rods 6 can be driven to move when the extrusion plate 8 moves, when the extrusion plate 8 moves to the maximum distance, the three positioning rods 6 can support the pipe to a position where the axis of the pipe is coincident with the axis of the first rotating ring 3, at the moment, the pipe can be limited in the three positioning rods 6, the pipe can stably stay at a cutting position, the pipe cannot shake in the cutting process, the pipe can be better cut, after the pipe is cut, the cut pipe can automatically fall off, then the extrusion plate 8 can return to the initial position under the action of the second spring 14, the action of the extrusion plate 8 is lost, the three positioning rods 6 can automatically return to the initial position to cancel the limitation on the pipe, then the pipe can move again, the pipe can be automatically limited when moving to the cutting position, and the pipe can be better cut, and can cancel the spacing to tubular product automatically after the cutting is accomplished, then can remove tubular product once more and cut the position, the in-process does not need staff's participation, not only can reduce staff's work load greatly, can also accelerate the cutting speed of tubular product greatly.

Specifically, avoidance grooves 31 are formed in the left side wall and the right side wall of the extrusion plate 8, triangular support plates 32 are arranged in the avoidance grooves 31, the inclined surfaces of the triangular support plates 32 are in contact with the side walls of the avoidance grooves 31, the triangular support plates 32 are connected to the left side wall of the first mounting plate 7 in a sliding mode in the vertical direction, and the top of each support plate is fixedly connected with a gas spring 33 for resetting the support plate; the during operation, promote the stripper plate 8 when the one end of tubular product and remove the back to the right, triangular support plate 32 can slowly spill over and dodge groove 31, the one end bottom surface of tubular product can contact with triangular support plate 32's top surface, stripper plate 8 can extrude the inclined plane of three support plates when removing the right, make the lateral wall rebound of tubular product of laminating all the time of triangular support plate 32, can make tubular product also can be supported by the one end of cutting when the cutting, can avoid tubular product emergence skew when the cutting, can make the better quilt of tubular product ability cut.

Specifically, the top of the bottom plate 1 is fixedly connected with a third mounting plate 34, the top of the third mounting plate 34 is rotatably connected with a blanking bearing plate 35 with an initial position being horizontal, the top surface of the blanking bearing plate 35 is flush with the top surface of the triangular bearing plate 32, the bottom surface of the blanking bearing plate 35 is fixedly connected with a third spring 36 for resetting the blanking bearing plate, a push rod 37 for driving the blanking bearing plate 35 to turn over is arranged above one end of the blanking bearing plate 35 away from the rotating shaft, one end of the push rod 37 is rotatably connected with a second slider 38, a torsion spring 39 for resetting the push rod 37 is sleeved on the rotating shaft, the second slider 38 is slidably connected in the vertical direction of the side wall of the L-shaped mounting plate 20, and the top of the second slider 38 is fixedly connected with the side wall of the fixed seat 17; when the cutting machine works, the fixed seat 17 can drive the second slide block 38 to move downwards together while moving downwards, the second slide block 38 can drive the push rod 37 and the torsion spring 39 to move downwards together, after the push rod 37 is contacted with the top surface of the blanking bearing plate 35, the push rod 37 can turn upwards under the action of the side wall of the blanking bearing plate 35 until the push rod 37 moves below the blanking bearing plate 35, the blanking plate can turn back to a horizontal position under the action of the torsion spring 39, then after the cutting is finished, when the fixed seat 17 drives the second slide block 38 to move upwards, the second slide block 38 can drive the push rod 37 to move upwards together, after the push rod 37 is contacted with the blanking bearing plate 35, the push rod 37 can drive the blanking bearing plate 35 to turn over at the top of the third mounting plate 34, after the blanking bearing plate 35 turns upwards to be contacted with the cut tube, the blanking bearing plate 35 can push the cut tube to move forwards, the cut pipe can slide along the inclined plane of the inclined blanking bearing plate 35, and through the arrangement of the blanking bearing plate 35 and the push rod 37, when the cutter disc 16 moves downwards to cut the pipe, the push rod 37 moves to the lower part of the blanking bearing plate 35, then when the fixed seat 17 drives the push rod 37 to move upwards after the cutting is finished, the push rod 37 drives the blanking bearing plate 35 to turn upwards, when the blanking support plate 35 is turned upwards to be in through contact with the cut pipe, the blanking support plate 35 can push the cut pipe to move forwards, so that the cut pipe can slide down along the inclined plane of the inclined blanking support plate 35, the cut pipe can better fall down, meanwhile, the horizontally arranged blanking supporting plate 35 can support the pipe when the pipe moves rightwards, so that the pipe can move better.

Specifically, one end of the positioning rod 6 close to the center of the first rotating ring 3 is rotatably connected with a rotating wheel 40; during operation, through the setting of runner 40, can make locating lever 6 better carry on spacingly to tubular product.

Specifically, a collecting box 41 positioned below the blanking bearing plate 35 is fixedly connected to the front wall of the bottom plate 1; during operation, the cut pipes can be better collected through the arrangement of the collecting box 41.

The air pressure in the first air bag is increased by extruding the first air bag, so that air is sprayed out from the nozzle, the sprayed air can remove attached dust, the air in the second air bag enters the sliding pipe through the vent hole by extruding the second air bag, the air entering the sliding pipe extrudes the piston to move outwards to drive the sliding rod to slide outwards and drive the dust collection box to move to the position obliquely below the nozzle, and the dust is just blown into the dust collection box; the extrusion motion of the first air bag and the extrusion motion of the extrusion plate form organic linkage, and the extrusion plate moves inwards before each cutting motion, so that the first air bag is extruded to enable gas to be sprayed out from the nozzle, dust does not need to be cleaned manually, and cost is saved; the outward sliding motion of the dust collection box and the extrusion motion of the extrusion plate form organic linkage, before each cutting motion, the extrusion plate moves inward to extrude the second air bag, gas enters the sealed sliding pipe from the inside of the second air bag through the vent hole to drive the piston block to move outward, further drives the sliding rod to move outward, further drives the dust collection box to move outward, and ensures that blown dust just falls into the dust collection box; when the dust collection box is arranged on the lower side of the lower material bearing plate, dust is not easy to blow out, the dust can be effectively stored, and when the dust collection box is positioned on the outer side of the lower material bearing plate, blown-out dust can just fall into the dust collection box, so that the dust can be easily collected.
