[0002] A winder is a device used to wind continuous materials into rolls. It is widely used in the production of paper, film, textiles, metal foil, etc. Its basic function is to wind long strips of material (such as paper, plastic film, metal strip, etc.) into cylindrical rolls at the final stage of the production process for subsequent storage, transportation and use. The role of the air shaft in the winder is to provide stable material winding and tension control. The air bag is filled with gas to increase the diameter of the shaft, ensuring that the material is tightly fixed on the shaft during the winding process.

[0024] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0025] When in use, the winder drives the inflatable shaft 4 to reel the material. During the use of the inflatable shaft 4, the external air source device inflates the airbag 5 through the air pipe 20. The expansion of the airbag 5 drives the multiple extension pieces 7 to move to the outside of the inflatable shaft 4. The extension piece 7 drives the key 8 to move outward to adjust the winding size of the inflatable shaft 4. On the contrary, the air source device evacuates air to shrink the airbag 5 and move the key 8 into the inflatable shaft 4. By opening the electromagnetic valves in the multiple branch pipes 74, the air inlet pipe 20 can pressurize the air intake in the sealing cylinder 71 through the multiple branch pipes 74, drive the piston 72 to move upward, and the piston 72 drives the telescopic rod 73 to extend outward. On the basis of the expansion of the airbag 5, the adjustable range of the key strip is increased. On the contrary, by opening the electromagnetic valve of the air outlet pipe 75, the pressure in the sealing cylinder 71 can be reduced to move the key 8 downward. By moving the clamping rod 178 into the movable groove 175, the clamping rod 178 squeezes the second spring 176 and moves out of the clamping groove 179 of the second bending plate 174. After the first bending plate 173 and the second bending plate 174 are unlocked, the first bending plate 173 and the second bending plate 174 can be rotated ninety degrees in opposite directions, and the first bending plate 173 and the second bending plate 174 can be pulled out from the two mounting plates, so that the first mounting plate 171 and the second mounting plate 172 can be separated, so as to facilitate the disassembly of the inflatable shaft 4, and facilitate the quick replacement of the reel or replacement and maintenance. By unscrewing the screws 13 out of the inflatable shaft 4, the cover plate 14 can be removed from both sides of the inflatable shaft 4, so that the airbag 5 and the structure inside the inflatable shaft 4 can be inspected; When the key 8 is worn and deformed during use, the key 8 is moved out of the inflatable shaft 4 through the airbag 5, and then the hand nut 12 is screwed out of the screw 11 to drive the key 8 to move upward, and the key 8 is separated from the extension 7, so that the key 8 can be disassembled and replaced separately; When winding or unwinding two materials of different thicknesses and lengths, the four differential bevel gears 24 are driven by the driving assembly 25 to work, so as to achieve the difference in rotation speed of the two inflatable shafts 4, thereby meeting the use requirements of different tensions.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
