Further optimization is carried out on the basis of the embodiment: the scissors 40 for cutting the air bag b are arranged between the packaging mechanism 20 and the feeding mechanism 30, when the air bag b is completely shrunk on the surface of the tracheal cannula a, and after the supporting claw 302 exits from the forming sleeve 201, the scissors 40 automatically cut the air bag b, and finally, redundant excess materials during heat shrinkage are manually removed.

The specific use mode of the invention is as follows: firstly, the trachea cannula a is clamped on the elastic chuck 101, the part of the trachea cannula a which is not clamped is placed on the supporting plate 102, the supporting plate 102 and the clamping block 103 are mutually clamped, then the supporting tube 104 and the expansion rod 105 are controlled to move towards the trachea cannula a, hot air is introduced into the supporting tube 104, the expansion rod 105 is aligned with an air passage c on the trachea cannula a and inserted, then the supporting tube 104 and the expansion rod 105 are moved towards the side of the packaging mechanism 20 and inserted into the trachea cannula a and the air passage c, the air cylinder connected with the pressing block 210 is controlled to move, the pressing block 210 clamps the trachea cannula a, then the air cylinder connected with the cutting knife 209 moves, and the cutting knife 209 cuts an air outlet cut on the surface of the trachea cannula a,

then the fixed base connected with the supporting plate 102 is controlled to move towards the elastic chuck 101 until the tracheal cannula a completely enters the sleeve 211, then the elastic chuck 101 is controlled to discharge the clamped tracheal cannula a, the control supporting tube 104 and the expanding rod 105 follow the supporting plate 102 and simultaneously move towards one side of the forming sleeve 201 until the tracheal cannula a passes through the forming sleeve 201,

then, a driving device connected with the accommodating rod 301 is controlled to be started, the accommodating rod 301 drives the air bag b to move towards one side of the forming sleeve 201 and enter the forming sleeve 201, the supporting claw 302 and the heat sealing element 202 are in the same position, and the supporting claw 302 drives the air bag b to expand outwards, so that the sleeve 211 extends into the control tube 303;

then controlling the cylinder connected with the forming sleeve 201 to start, enabling the forming sleeve 201 to move towards the middle, starting the cylinder connected with the heat sealing piece 202 at one end with the supporting claw 302, driving the heat sealing piece 202 to clamp the supporting claw 302 to move towards the middle, enabling the clamped airbag b to be heated, softened and compressed until the airbag b is compressed on the sleeve 211, enabling the supporting claw 302 to retract into the accommodating rod 301 by controlling a driving component connected with the supporting claw 302 after the supporting claw 302 is compressed to be hijacked with the sleeve 211, starting a suction pump connected with the forming sleeve 201, enabling the suction pump to receive air to generate negative pressure, enabling the airbag b to be adsorbed on the inner wall of the forming groove 203 for forming, enabling the heat sealing piece 202 to move towards the middle under the driving of the cylinder at one end without the supporting claw 302, directly heating the airbag b and compressing towards the middle until the accommodating rod 301 is completely withdrawn from the forming sleeve 201, namely, the airbag b can be hot-pressed on the sleeve 211 (as shown in the drawings 11(a) - (b) in the specification);

after the air bag b is compressed on the sleeve 211, the supporting plate 102 is controlled to move towards the elastic chuck 101, so that the sleeve 211 is withdrawn from the forming sleeve 201, that is, the heat sealing piece 202 drives the air bag b to be pressed towards the middle to the surface of the endotracheal tube a, and the air bag b is cut by the scissors 40 (as shown in fig. 11(b) - (c);

after the air bag b is heat sealed on the surface of the endotracheal tube a, the processed endotracheal tube a is taken out from the forming sleeve 201 by controlling the direction of the supporting tube 104 and the expanding rod 105 moving away from the elastic collet 101, and then the product with the air bag b manufactured can be obtained (as shown in the attached fig. 11(c) - (d) of the specification).
