The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 11, an adjustable multi-bundle fiber spiral winding device comprises a frame body 1 and a plurality of yarn guides 2, wherein the frame body 1 is provided with a through hole 100, the yarn guides 2 are provided with a plurality of yarn guides 2, the yarn guides 2 are distributed annularly along the center of the through hole 100 and are all connected with the frame body 1 in a sliding manner, and fibers can extend out of each yarn guide 2; the frame body 1 is provided with a telescopic mechanism 8, and each wire guide head 2 is driven to stretch and retract through the telescopic mechanism 8.

When in use, a workpiece to be wound passes through the through hole 100 on the frame body 1 and is fixed by the corresponding fixing device. The workpiece can be driven to rotate and move by the fixing device. The fixing device can be realized by adopting various structures, if the fixing device can be provided with a chuck and a movable base, the chuck is arranged on the base, the workpiece is clamped by the chuck and is driven to rotate, and the base drives the chuck and the workpiece to move.

During winding, a plurality of bundles of fibers are drawn out from a creel and are subjected to tension control by the conventional tension controller, and each bundle of fibers respectively passes through the corresponding yarn guide head 2; the single fibers extending out of each wire guide head 2 are gathered into a plurality of bundles of fibers, the bundles of fibers are evenly distributed on the surface of the workpiece, and the fibers are not overlapped and crossed. And then the plurality of bundles of fibers are simultaneously wound on the surface of the workpiece in a spiral shape through the rotation and the movement of the workpiece.

When winding, the godet head 2 can stretch out and draw back according to the shape change of a workpiece (such as a pressure container liner), so that the fiber can be well attached to the outer surface of the workpiece, and the winding effect and the adaptability are further improved; meanwhile, the device can also be suitable for workpieces of different specifications.

Furthermore, the godet heads 2 are connected with the frame body 1 in a sliding mode through a connecting sleeve 7, the connecting sleeve 7 is connected with the frame body 1 in a rotating mode, the godet heads 2 are connected with the connecting sleeve 7 in a sliding mode, and the telescopic mechanism 8 drives the godet heads 2 to slide along the connecting sleeve 7; the device also comprises a first driving mechanism 3, wherein the first driving mechanism 3 is connected with the connecting sleeve 7 and can drive the godet head 2 to rotate.

The arrangement of the connecting sleeve 7 ensures that the godet 2 can be rotated while also being able to be displaced along the connecting sleeve 7. Specifically, a protrusion can be arranged in the connecting sleeve 7, a corresponding key groove is arranged on the wire guide head 2, and sliding is realized through the matching of the key groove and the protrusion; of course, the inner hole of the connecting sleeve 7 can also be set to be a prismatic hole, and the outer part of the wire guide head 2 is also prismatic; so that those skilled in the art can adopt various structural arrangements to realize the sliding connection between the two.

Therefore, in the winding process, each yarn guide head 2 can drive each fiber to rotate, so that each fiber is better attached to the outer surface of the workpiece.

Further, the godet 2 may be provided in various structures as long as it can ensure the passage of the fiber, and preferably, the following structure is adopted:

the thread guide head 2 is a hollow rod, two ends of the hollow rod are provided with openings, and fibers can enter the hollow rod from the opening at one end, so that the opening at the other end extends out; the other end of the hollow rod is flat, and the shape of the opening of the other end is the same as the cross-sectional shape of the fiber. A common fiber has a rectangular cross-sectional shape, and thus the other end opening is also rectangular in shape. Through the structure, the fiber can be driven to rotate correspondingly while the godet head 2 rotates. A gap is formed between the opening at the other end and the fiber, so that the fiber can pass through the gap; of course, smaller gaps can be designed, provided that fiber movement is ensured.

Further, the first driving mechanism 3 includes a first driving element 300 and a first gear transmission 301, and the first driving element 300 is connected with each connecting sleeve 7 through the first gear transmission 301 to drive each godet 2 to rotate. The adoption of a gear transmission mode can ensure the stable and accurate rotation of each yarn guide head 2.

Further, the first gear transmission mechanism 301 comprises a first gear ring 3010 and a first connecting post 3011, the first gear ring 3010 is rotatably connected to the frame body 1, and the first driving element 300 is connected to the first gear ring 3010 and drives the first gear ring 3010 to rotate; the first connecting columns 3011 are provided with a plurality of connecting columns and are rotatably connected with the frame body 1, and each wire guide head 2 is connected with one first connecting column 3011; the first connecting column 3011 is driven to rotate through rotation of the first gear ring 3010, the first connecting column 3011 drives the connecting sleeve 7 (the wire guide head 2) to rotate, one end of the first connecting column 3011 is provided with a first connecting gear 3012 meshed with the first gear ring 3010, the other end of the first connecting column 3011 is provided with a first transmission gear 3014, and the first transmission gear 3014 is meshed with a first driving gear 3013 arranged on the connecting sleeve 7.

When the first gear ring 3010 rotates, the first connecting column 3011 can be driven to rotate by meshing with the first connecting gear 3012 at one end of the first connecting column 3011; the first connecting post 3011 rotates, and can be engaged with a first driving gear 3013 arranged on the connecting sleeve 7 through a first driving gear 3014 at the other end of the first connecting post, so as to drive the godet 2 to rotate. Therefore, when the first ring gear 3010 rotates, all the godets 2 can be driven to rotate.

Further, since the sizes of the workpieces are different, the godet heads 2 (fibers) used for winding the workpieces of different sizes are also different; simple examples are: when the winding is smaller, the winding operation can be carried out through 20 wire guides 2; when winding larger sizes, 40 godets 2 may be required. Although the above structure can drive all the godet heads 2 to rotate at the same time, the adaptability is poor, and the corresponding control cannot be performed according to the requirement. Therefore, the respective control is realized by the following structure, and the variable driving is realized by driving the corresponding number of the godet heads 2 to rotate according to the specification of the workpiece, and the following structure is preferably adopted:

the first gear ring 3010 is connected with the frame body 1 in a sliding manner through the slewing bearing 4, the first gear ring 3010 is connected with the slewing bearing 4 in a sliding manner, a third driving mechanism 5 is arranged between the first gear ring 3010 and the slewing bearing 4, and the first gear ring 3010 is driven to slide along the axial direction through the third driving mechanism 5; the first connecting columns 3011 are divided into at least two groups, and can be engaged with the first connecting gear 3012 on one or more groups of first connecting columns 3011 through the movement of the first gear ring 3010 to drive the corresponding wire guide head 2 to rotate.

Specifically, the method comprises the following steps: the inner ring 400 of the rotary support 4 is fixedly connected with the frame body 1, and the outer gear ring 401 of the rotary support 4 is connected with the first gear ring 3010 in a sliding manner, or vice versa. For the sliding connection, a person skilled in the art may set corresponding sliding grooves, sliding pillars 402, and the like to implement the sliding connection, that is, the sliding pillars 402 are disposed on the outer gear ring 401, the first gear ring 3010 is connected to the sliding pillars 402, and the first gear ring 3010 is provided with corresponding connection holes. As the third driving mechanism 5, various members having a telescopic function such as an electric telescopic cylinder and a screw elevator; taking the electric telescopic cylinder as an example, a cylinder body of the electric telescopic cylinder is fixedly connected with the outer gear ring, a rod body of the electric telescopic cylinder is fixed with the outer gear ring 401, and the first gear ring 3010 slides (moves) through the expansion and contraction of the rod body.

For example, the following steps are carried out: when there are 60 first connecting posts 3011, they can be divided into three groups, each group including 20 connecting posts (which of course may not be equally divided). When the first ring gear 3010 moves, it engages with the first link gear 3012 on the first link post 3011 (20) in the first group, and drives 20 first link posts 3011 to rotate at the same time, that is, drives 20 wire guides 2 to rotate to wind a small-sized workpiece.

When the first gear ring 3010 continues to move, it can engage with the first connecting gears 3012 on the two groups of first connecting posts 3011, and simultaneously drive 40 first connecting posts 3011 to rotate, that is, drive 40 wire guides 2 to rotate to wind the medium-sized workpiece.

When the first ring gear 3010 moves further, it can engage with the first connecting gears 3012 on three (all) groups of first connecting posts 3011, and simultaneously drive 60 first connecting posts 3011 to rotate, that is, drive 60 wire guides 2 to rotate to wind the medium-sized workpiece.

Specifically, the method comprises the following steps: the axial lengths of the first connecting gears 3012 on the first connecting posts 3011 in each group may be set to be different, and the axial lengths of the first connecting gears 3012 in each group are gradually increased or shortened, so as to ensure that the first gear rings 3010 can be engaged with the corresponding first connecting gears 3012 in the moving process, and increase or decrease the number of the first gear rings engaged with the first connecting gears 3012. Of course, the arrangement position of the first connecting gear 3012 in each group may be changed, and the above-described function may be achieved as well.

For example, the following steps are carried out: the first connecting columns 3011 are provided with 60, which are also divided into three groups; the axial length of the first connecting gear 3012 on the first connecting post 3011 in the first group > the axial length of the first connecting gear 3012 on the first connecting post 3011 in the second group > the axial length of the first connecting gear 3012 on the first connecting post 3011 in the third group. Therefore, when the first ring gear 3010 moves, it can mesh with the first connecting gear 3012 in the first group; while continuing to move, the first connecting gear 3012 in the first group and the second group can be engaged at the same time; further movement may be simultaneously engaged with the first connecting gear 3012 of the first, second and third sets.

Since the first ring gear 3010 needs to be driven to move by the third driving mechanism 5, and at the same time, needs to be driven to rotate by the first driving piece 8010; to ensure that the first drive element 300 is always connected to the first ring gear 3010, one skilled in the art may suitably increase the axial length of the first ring gear 3010 to ensure that it is connectable to the first drive element 300 regardless of its movement.

Of course, a person skilled in the art may also adopt a sliding connection between the first driving member 300 and the pivoting support 4 or the frame body 1, so as to ensure that the first driving member 300 can move together with the first gear ring 3010.

Therefore, those skilled in the art can adopt various structures to realize that the first driving member 300 is connected with the first gear 3010 and drives the first gear 3010 to rotate.

However, in order to improve the overall operation effect, the following structure is preferably adopted:

further, the first driving element 300 is engaged with the teeth (the outer gear ring 401) on the slewing bearing 4 through the gear or the first worm 6, and drives the first gear ring 3010 to rotate. By adopting the structural arrangement, the first driving element 300 can be fixed on the frame body 1 and does not need to move together with the first gear ring 3010, so that the stability in the driving process can be ensured.

The telescopic mechanism 8 can be realized by adopting various structures, and no matter what structure is adopted, the telescopic mechanism can be realized as long as the telescopic mechanism can realize the wire guide head 2, such as: a plurality of telescopic cylinders can be arranged, and the stretching of the silk guide head 2 is driven by the stretching of the telescopic cylinders.

The shifting fork 8000 is adopted, so that the movement of the godet head 2 can be conveniently controlled while the rotation of the godet head is not influenced; compared with the arrangement of a plurality of telescopic cylinders, the structure is simpler and more reasonable, and the arrangement of unnecessary power can be reduced.

Further, in order to conveniently realize the connection between the shifting fork 8000 and the godet head 2, a clamp 10 is fixed on the godet head 2, a groove connected with the shifting fork 8000 is formed in the clamp 10, and the end part of the shifting fork 8000 can be clamped into the groove to be rotatably connected with the clamp 10.

The rotation of the nut 80120 in the screw nut 80120 mechanism is converted into the movement of the screw rod 80121, so that the shifting fork 8000 is driven to move along the guide rod 8001.
