The working principle is as follows:

when in use, the plastic bottle 19 is placed on an air chuck 18 through a manipulator, then the second servo motor 16 drives the second rotating shaft 73 to rotate, further drives the driving disc 77 to drive the driven disc 74 to rotate through the shifting post 78, the second servo motor 16 rotates for one circle, then the driven disc 74 rotates for one third of a circle, further drives the driving chuck on the rotating frame 15 to rotate for 120 degrees, so that the loaded plastic bottle 19 rotates to one end of the gas injection mechanism 5, meanwhile, the first servo motor 12 rotates to drive the driving bevel gear 13 to rotate, further drives the bevel gear ring 11 to rotate, further drives the rotating disc 10 to rotate, so that the finger cylinder 14 rotates, the gap between the two clamping blocks 21 on the finger cylinder 14 moves to the line of the rotation of the plastic bottle 19, when the plastic bottle 19 rotates to be close to one end of the finger cylinder 14, the bottle mouth of the plastic bottle 19 rotates to be just between the two clamping blocks 21 on the finger cylinder 14, then the plastic bottle 19 continues to rotate below the gas injection mechanism 5, the finger cylinder 14 also rotates along with the plastic bottle 19 until the plastic bottle 19 moves to a position right below the gas storage cylinder 51, at the moment, the finger cylinder 14 drives the clamping block 21 to clamp the mouth of the plastic bottle 19, so that the limiting ring 23 is clamped in the clamping groove 22, then the fourth servo motor 64 rotates to drive the third threaded rod 63 to rotate, so that the threaded cylinder 62 can be driven to lift, so that the threaded sleeve drives the finger cylinder 14 to clamp the plastic bottle 19 to lift, so that the mouth of the plastic bottle 19 abuts against the rubber pad 53 at the bottom of the gas storage cylinder 51 for sealing, meanwhile, the pneumatic chuck 18 firstly releases the clamping on the plastic bottle 19, then after the plastic bottle 19 is sealed with the rubber pad 53, the bottom of the plastic bottle 19 is clamped again, the plastic bottle 19 is limited, the stability of clamping on the plastic bottle 19 is improved, after the plastic bottle 19 is clamped, the air pump is connected with the air inlet pipe 516, so that the air pump inflates the air storage cylinder 51 through the air inlet pipe 516, air enters the plastic bottle 19, the plastic bottle 19 is inflated, the air pressure in the plastic bottle 19 is increased, the bottle body of the plastic bottle 19 is supported, when the double-sided adhesive tape 20 is used for adhering the double-sided adhesive tape to the bottle body of the plastic bottle 19, the bottle body of the plastic bottle 19 cannot be greatly deformed, the adhering precision of the double-sided adhesive tape can be improved, when more air is filled into the bottle body of the plastic bottle 19, in order to prevent the bottle body from being greatly deformed, when the air pressure in the plastic bottle 19 is high, the air pushes the piston 54, the piston 54 slides upwards and extrudes the spring 59, when the piston 54 slides to one end of the air exhaust hole 55, the air exhaust hole 55 is opened, the interior of the air storage cylinder 51 is communicated with the outside, and the excessive air can be exhausted through the air exhaust hole 55, the pressure in the plastic bottle 19 after the gas is exhausted is reduced, so that the spring 59 continuously pushes the piston 54 downwards to block the exhaust hole 55, pressure maintaining is performed in the plastic bottle 19, the pressure in the plastic bottle 19 is kept within a certain range, after the gas is inflated, the first servo motor 12 rotates to drive the turntable 10 to rotate, the finger cylinder 14 can be driven to clamp the plastic bottle 19 to rotate, and the double-sided adhesive tape is pasted on the surface of the plastic bottle 19 for 360 degrees in a matching manner by the double-sided adhesive tape pasting machine 20;

because the plastic bottles 19 with different sizes or the plastic bottles 19 with different wall thicknesses are different in deformation amount due to the bearing of the air pressure, people can adjust the inflated air pressure according to the sizes and the wall thicknesses of the different plastic bottles 19, people rotate the inner hexagonal knob 517 through a wrench, and then drive the second threaded rod 58 to rotate, so that the second threaded rod 58 moves downwards, the sliding plate 57 is driven to downwards extrude the spring 59, and the spring 59 is compressed, thereby increasing the initial elasticity of the spring 59, and enabling the gas to push the piston 54 to need larger force, therefore, aiming at the thicker and non-deformable plastic bottles 19, the pressure-maintaining air pressure inside the plastic bottles 19 can be increased, so that the plastic bottles are suitable for the different plastic bottles 19, and for the plastic bottles 19 with different heights, the third servo motor 45 rotates to drive the first threaded rod 44 to rotate, and then the L-shaped plate 43 can be driven to go up and down, so that the top plate 8 can go up and down, therefore, the height of the turntable 10 is adjusted, the gas injection mechanism 5 and the finger cylinder 14 are lifted, and the distance between the finger cylinder 14 and the air chuck 18 is adjusted, so that the plastic bottles 19 with different heights are adapted.
