[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can achieve synchronous spiral winding of multiple bundles of fibers, improve the winding efficiency, solve the problems of difficult yarn feeding, easy stress concentration in the wound product, and difficult intervention in the winding process.

[0016] Among them, the radial telescopic mechanism of the wire guide head changes according to the change in the diameter of the rotating body to be wound, and always keeps the end of the wire guide tube in contact with the outer surface of the rotating body in the best state. At the same time, the self-rotation mechanism of the wire guide head can make the fiber filaments wind at different helix angles according to needs to obtain products with different properties. At the same time, it can also make the fiber filaments fit more closely to the rotating body, the fiber filaments are evenly distributed, do not cross or overlap, and reduce the use of fibers.

At the same time, a guide wheel tangent to the rectangular neutral plane is installed at the tail, which can make the fiber filaments transition more smoothly during the winding process, avoid excessive stress on the fibers at the outlet due to excessive tension, and at the same time, the compaction effect of the guide wheel makes the fiber filaments fit more closely to the outer surface of the rotating body.

[0018] There is a certain misalignment between the circumferential distribution of the film winding roller and the circumferential distribution of the unwinding roller, which can avoid 180-degree separation of the film yarn. At the same time, the presence of the damping motor enables the yarn to maintain an appropriate tension during the transfer process.

[0034] During operation, two yarn feeding drive motors 501 are used as drive inputs to drive the corresponding first yarn feeding drive shafts 502, driving the meshing movement between the first yarn feeding drive pinion 503 and the yarn feeding drive large gear 544. The yarn feeding drive large gear 544 has a wide tooth width and can mesh with the first yarn feeding drive pinion 503 and the second yarn feeding drive pinion 504 at the same time, so that the second yarn feeding drive shaft 530 can be driven. The second yarn feeding drive shaft 530 then drives the meshing first yarn feeding drive bevel gear 531 and second yarn feeding drive bevel gear 532, and then the third yarn feeding drive shaft 529 is driven. The third yarn feeding drive shaft 529 drives the drive roller 535. The six rollers form a smooth spatial curve to gently guide the fiber filaments to the drive roller 535. The air cylinder 543 is inflated to push the push rod 541 forward. The push rod 541 is connected to the driven roller shaft 539, and then the driven roller 540 is pushed until the driven roller 540 and the drive roller 535 clamp the fiber filaments. Under the driving action of the clamping and friction, the fiber filaments will automatically be sent from the fiber roll to the wire guiding head assembly; when the sensor detects that the tension of the fiber filaments does not meet the conditions, the damping motor 509 drives the unwinding roller 507 to adjust the tension; during normal winding, the film winding drive motor 512 will drive the film winding roller 511 to wind and recycle the film peeled off from the fiber filaments by rotation. The above three sets of mechanism systems do not interfere with each other and work independently.

[0035] The working process of the present invention is as follows: First, it winds around the position of the inner bottle mouth. Since the diameter at the bottle mouth position is constantly changing, from small to large, to ensure the uniformity of winding, the contact area of each bundle of fibers with the inner liner is also gradually increasing. When transitioning from the bottle mouth to the bottle body, the contact area between the fibers and the inner liner is the largest. When starting to wind from the bottle mouth position, the helical-bevel gear reduction motor 101 inputs power to drive the radial telescopic drive shaft 102, driving the radial telescopic drive pinion 103 to rotate counterclockwise. The engaged radial telescopic drive gear 104 moves clockwise. Under the guiding action of the guide rail 110 and the slider 109, the connecting rod 106 drives the slider 109 to move in the direction of a smaller radius. The slider 109 is connected to the wire guiding tube 401 through the connecting plate 108 and the wire guiding head connector 107, and the wire guiding head assembly moves in the direction of a smaller radius.

[0036] At this time, all the wire guiding head assemblies maintain synchronous movement. When the guide wheel 402 of the wire guiding head assembly is tangent to and fits the inner bottle, the helical-bevel gear reduction motor 101 stops, and all actions stop. At this time, the wire guiding head assembly extends to an appropriate position. Subsequently, the air cylinder 543 is inflated to push the push rod 541 forward. The push rod 541 is connected to the driven roller shaft 539, and then the driven roller 540 is pushed until the driven roller 540 and the driving roller 535 clamp the fiber filament. The air cylinder 543 stops inflating and maintains the current state. At this time, all the driven rollers 540 and the air cylinder 543 reach the correct positions, and the preparation work is completed.

[0037] The side of the fiber starts to wind, causing the inner liner to rotate circumferentially and move axially. At the same time, the two yarn feeding drive motors 501 are used as drive inputs to drive the corresponding first yarn feeding drive shafts 502, driving the meshing movement between the first yarn feeding drive pinions 503 and the yarn feeding drive gears 544. The yarn feeding drive gear 544 has a wide tooth width and can be meshed with the first yarn feeding drive pinion 503 and the second yarn feeding drive pinion 504 at the same time, so that the second yarn feeding drive shaft 530 is driven; the second yarn feeding drive shaft 530 then drives the engaged first yarn feeding drive bevel gears 531 and second yarn feeding drive bevel gears 532, and then the third yarn feeding drive shaft 529 is driven. The third yarn feeding drive shaft 529 drives the driving roller 535. Six rollers form a smooth space curve to gently guide the fiber filament to the driving roller 535. The air cylinder 543 is inflated to push the push rod 541 forward. The push rod 541 is connected to the driven roller shaft 539, and then the driven roller 540 is pushed until the driven roller 540 and the driving roller 535 clamp the fiber filament, and the fiber filament clamped by the driving roller 535 and the driven roller 540 is driven; At the same time, the helical-bevel gear reduction motor 101 starts to rotate in the opposite direction, and its speed is controlled so that the wire guide head assembly retracts as the radius of curvature at the liner head changes. At the same time, the spin drive motor 301 outputs counterclockwise, drives the first spin drive shaft 302, drives the first spin drive pinion 303 to engage with the spin drive gear 313 for transmission, and then drives a plurality of second spin drive pinions 306, and the second spin drive pinions 306 drive the second spin drive shaft 304 to rotate, and the plurality of second spin drive shafts 304 drive the corresponding first pulleys 310, and the first pulley 310 and the second pulley 308 are driven, and the second pulley 308 is connected with the wire guide tube 401 by the coaxial shaft key and keyway. The wire guide tube 401 is driven, and the speed of the spin drive motor 301 is controlled, so that the wire guide head rotates as the radius of curvature at the liner head changes. At this time, the wire guide head assembly both rotates and retracts radially.

[0038] When the winding reaches the transition position between the bottle mouth and the bottle body, the wire guide assembly retracts to the maximum position, and the contact area between the fiber and the liner is the largest. At this time, the helical-bevel gear reduction motor 101 and the spin drive motor 301 stop rotating. Continue to drive the liner to move axially and rotate circumferentially, and spirally wind the bottle body. At this stage, the wire guide assembly does not move. After completing the winding of the bottle body, at the transition position between the bottle body and the head at the other end, the helical-bevel gear reduction motor 101 starts to output clockwise, and controls its rotation speed so that the wire guide assembly extends along with the change of the radius of curvature at the liner head. At the same time, the spin drive motor 301 starts to output clockwise, and controls the rotation speed of the spin drive motor 301 so that the wire guide assembly rotates along with the change of the radius of curvature at the liner head. At this time, the wire guide assembly both rotates and extends radially. In conjunction with the axial movement and circumferential rotation of the liner, the spiral winding of the other end of the liner is completed, thereby completing the spiral winding operation of the first layer of the liner.
