the method comprises the following steps: firstly, the shielding cloth 22 is limited and fixed through the connecting device 2;

step two: then the worker controls the first motor 4 to drive the first lead screw 5 to rotate through the controller 28, then the first lead screw 5 drives the composite tube 12 to move to the right through the moving seat 7, the connecting seat 8 and the supporting seat 6, meanwhile, the worker drives the second lead screw 17 to rotate on the inner side of the second sliding block 18 through the third motor 16, so that the second lead screw 17 drives the second electric telescopic rod 19, the protective shell 15, the second motor 14 and the cutter 13 to move in the horizontal direction through the second sliding block 18 until the vertical central line of the cutter 13 is overlapped with the vertical central line of the shielding cloth 22, when the composite tube 12 moves to the lower side of the cutter 13, the worker stops moving the composite tube 12, then the worker drives the protective shell 15 to move downwards through the second electric telescopic rod 19, so that the protective shell 15 drives the cutter 13 to move downwards through the second motor 14 to cut the composite tube 12, and simultaneously the second motor 14 also drives the cutter 13 to rotate forwards from back, the scraps generated by the cutting knife 13 cutting the composite pipe 12 collide with the shielding cloth 22 and then fall to the inner side of the collection box 24, when cutting is performed, a worker carries out limiting and fixing on the sealing ring 25 through the fixed placing device 1, then the heating plate 23 drives the sealing ring 25 to move left under the action of the second lead screw 17 until the left groove of the heating plate 23 is clamped with the composite pipe 12, the composite pipe 12 and the sealing ring 25 are simultaneously heated through the heating plate 23, after the plastic at the port of the composite pipe 12 is melted, the heating plate 23 moves right and is separated from the composite pipe 12, then the worker drives the third electric telescopic rod 21 to rotate 180 degrees anticlockwise through the fourth motor 20, the third electric telescopic rod 21 drives the sealing ring 25 to rotate from the right side to the left side through the heat insulation frame 26 and the heating plate 23, and then the composite pipe 12 is attached to the sealing ring 25 at the inner side of the heating plate 23 under the action of the first lead screw 5, and heating by the heating plate 23 again to enable the composite pipe 12 to be tightly abutted and bonded with the sealing ring 25, extruding and shaping, so that the sealing of the composite pipe 12 is completed, and the composite pipe 12 is taken down after the sealing is completed and then enters the next round of sealing.

The working process is as follows: before the device is used, power is supplied by an external power supply, a worker firstly hangs shielding cloth 22 on a hook 203, meanwhile, a second spring 205 on the inner side of the hook 203 can support the hook 203, so that the hook 203 can tension the shielding cloth 22, then the worker places a composite tube 12 on the inner side of a supporting seat 6, then the worker controls a first electric telescopic rod 11 to drive a clamping block 10 and an anti-slip pad 9 to clamp and limit the composite tube 12 through a controller 28, then the worker controls a first motor 4 to drive a first lead screw 5 to rotate through the controller 28, then the first lead screw 5 drives the composite tube 12 to move towards the right through a moving seat 7, a connecting seat 8 and the supporting seat 6, and simultaneously the worker drives a second lead screw 17 to rotate on the inner side of a second sliding block 18 through a third motor 16, so that the second lead screw 17 drives a second electric telescopic rod 19 through the second sliding block 18, The protective shell 15, the second motor 14 and the cutter 13 move in the horizontal direction until the cutter 13 coincides with the vertical central line of the shielding cloth 22, when the composite pipe 12 moves to the lower side of the cutter 13, the composite pipe 12 stops moving, then the worker drives the protective shell 15 to move downwards through the second electric telescopic rod 19, the protective shell 15 drives the cutter 13 to move downwards through the second motor 14 to cut the composite pipe 12, meanwhile, the second motor 14 also drives the cutter 13 to rotate forwards from the back, so that the scraps generated when the cutter 13 cuts the composite pipe 12 collide the shielding cloth 22 and then fall to the inner side of the collection box 24, the worker coincides the sealing ring 25 with the left end face of the pressure ring 17 during cutting, then the controller 28 controls the micro vacuum pump 106 to work, the micro vacuum pump 106 sucks the sealing ring 25 through the vacuum pipe 105 and the pressure ring 107, and then the worker pulls the adjusting rod 104 downwards, the adjusting rod 104 moves downwards along the first sliding block 108 and the limiting head 111, the adjusting rod 104 drives the sealing ring 25 to move downwards through the pressing ring 107 until the sealing ring 25 is aligned with the groove of the heating plate 23, meanwhile, the first spring 110 drives the limiting head 111 to be clamped with the adjusting rod 104, limiting of the adjusting rod 104 is achieved, then a worker drives the adjusting rod 104 to move leftwards through the first sliding block 108, the adjusting rod 104 drives the sealing ring 25 to be placed into the inner side of the heating plate 23 through the pressing ring 107, after cutting is completed, the cutter 13 moves upwards under the action of the second electric telescopic rod 19 to reset, simultaneously, the heating plate 23 drives the sealing ring 25 to move leftwards under the action of the second lead screw 17 until the groove on the left side of the heating plate 23 is clamped with the composite pipe 12, the composite pipe 12 and the sealing ring 25 are simultaneously heated through the heating plate 23, and after plastics at the port of the composite pipe 12 are melted, heating plate 23 moves to the right and breaks away from with compound pipe 12, then the staff drives third electric telescopic handle 21 anticlockwise rotation 180 degrees through fourth motor 20, make third electric telescopic handle 21 drive seal ring 25 through thermal-insulated frame 26 and heating plate 23 and turn to the left side by the right side, then make compound pipe 12 and the inboard seal ring 25 laminating of heating plate 23 be in the same place under first lead screw 5's effect, heat through heating plate 23 once more, make compound pipe 12 and seal ring 25 support tight bonding, the extrusion, the design, thereby accomplish the sealing to compound pipe 12, take off compound pipe 12 after sealing the completion, then get into the sealing of next round.
