It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0025] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0026] As Figures 1-9 shown, the utility model embodiment provides a compatible inside and outside yarn group pay-off support device, which comprises two bearing seats 4 arranged symmetrically, and the inside of the two bearing seats 4 is respectively provided with a first rotating rod 3 and a second rotating rod 8, the first rotating rod 3 and the second rotating rod 8 are commonly provided with a pneumatic tensioning shaft 5 at the end close to each other, the outside of the pneumatic tensioning shaft 5 is provided with a plurality of split support rings 6, the surface of the split support ring 6 is provided with an arc-shaped groove 12, and the inside of the arc-shaped groove 12 is provided with an elastic limiting ring 13.

[0027] The split support ring 6 is an arc-shaped structure, and a plurality of split support rings 6 are spliced to form a ring-shaped support assembly coaxial with the pneumatic tensioning shaft 5.

[0028] The compatible inside and outside yarn group pay-off support device further comprises a base 1, and the two sides of the surface of the base 1 are respectively provided with a support frame 2, and the bearing seat 4 is installed on the surface of the support frame 2. The side surface of the support frame 2 is provided with a pneumatic disc brake 10, the surface of the second rotating rod 8 is provided with a brake disc 9, and the brake disc 9 and the pneumatic disc brake 10 are matched to realize brake control.

[0029] The utility model discloses an embodiment provides a kind of compatible inside and outside yarn ball's pay-off support device, to solve the problem that existing winding equipment only supports outside yarn ball, cannot stable adaptation inside yarn ball, especially under the background of cost control and equipment versatility requirement gradually promotion, the device is adapted by the differentiation of structure, realizes the compatible support and stable pay-off of two different structure yarn ball.

[0030] The pay-off support device includes a base 1, the two sides of the base 1 are provided with support frames 2, a bearing seat 4 is installed on the surface of each support frame 2, a first rotating rod 3 and a second rotating rod 8 are respectively arranged in the two bearing seats 4, and a pneumatic tensioning shaft 5 is connected and installed at the end of the two rotating rods close to each other. The pneumatic tensioning shaft 5 is a mature technology, has a self-tightening function, and makes the external expansion key pop out by inflating the inner cavity to reliably lock different yarn balls. For the outside yarn ball 14 with a paper tube structure (preset support tube), the pneumatic tensioning shaft 5 can be directly fitted on the outside, and the yarn ball can be quickly locked and rotated by relying on the pneumatic expansion function, so that the structure is stable and easy to disassemble and assemble. For the inside yarn ball 7 without a paper tube structure, the yarn ball cannot be directly positioned by the tensioning shaft, and needs to be further supported radially by an external structure.

[0031] To solve the above problems, a plurality of split support rings 6 are fitted on the outside of the pneumatic tensioning shaft 5, the split support rings 6 are designed in an arc shape, the plurality of split support rings 6 are spliced to form a coaxial annular support assembly around the pneumatic tensioning shaft 5, the overall structure is compact, and is suitable for annular wrapping and stable positioning of yarn balls without a core. An arc-shaped groove 12 is arranged on the outer surface of each split support ring 6, a plurality of arc-shaped grooves 12 form a continuous ring groove after splicing, and an elastic limiting ring 13 is embedded in the ring groove. The elastic limiting ring 13 penetrates through the plurality of arc-shaped grooves 12 formed by splicing, fixes the position of the split support ring 6 to prevent axial sliding, so that the split support ring 6 always maintains a stable coaxial state, and provides a complete and firm support basis for yarn balls without a core structure. Through this structure, the inside yarn ball can be directly placed on the plurality of spliced split support rings 6 for pay-off operation.

[0032] A pneumatic disc brake 10 is installed on the side surface of the support frame 2, and a brake disc 9 is arranged on the outer surface of the second rotating rod 8. The brake disc 9 and the pneumatic disc brake 10 cooperate to form a pay-off tension control system. A friction type brake structure is formed between the brake and the brake disc, which is a mature control scheme and is widely used in various industrial transmission devices. The brake can apply a constant or adjustable braking force to the rotating part during the operation of the device, so as to ensure the constant tension of the yarn during the pay-off process and avoid problems such as broken line and loose line. The clamping force of the pneumatic adjusting brake 10 can be adjusted to accurately control the rotation damping of the brake disc 9, so as to realize stable pay-off tension adjustment under different yarn ball specifications and further improve the practical performance of the device.

[0033] The overall structural design enables the device to adapt to different types of yarn balls without replacing the main components, especially providing complete covering support for the inner extraction yarn ball without a paper tube by combining the support mode, realizing the coaxiality, balance and stability during the unwinding process. The device has obvious cost advantage and universality, and can be widely used in the fields of glass fiber, composite material, industrial winding, cable pretreatment and the like, solves the technical problems such as inflexible structure adaptation of traditional equipment, unavailability of inner extraction yarn ball and complex switching process, and has significant industrial application prospect.

[0034] In the embodiment, the elastic limiting ring 13 is an elastic limiting spring with a ring structure. It is arranged inside the arc-shaped groove 12 of the split support ring 6 formed by splicing, penetrates through the whole ring-shaped support assembly, and realizes overall limiting and elastic cooperation of all split support rings 6.

[0035] The ring structure of the elastic limiting spring enables it to continuously limit all split support rings 6 in the axial direction, avoids axial displacement of a single support ring due to rotation vibration or load fluctuation during work, and thus guarantees the stability and coaxiality of the overall structure of the ring-shaped support assembly. At the same time, since it has elastic characteristics, when there is a slight tolerance error or size change caused by thermal expansion and cold contraction during splicing of the split support ring 6, the elastic structure can automatically adjust and exert a slight elastic force, realize dynamic compensation and self-adaptive compression, effectively improve the assembly tightness between components, and avoid phenomena such as looseness, dislocation or vibration misplacement.

[0036] In addition, compared with the rigid limiting piece, the elastic limiting spring does not produce local concentrated stress when stressed, can better disperse the load, prolong the structure life and reduce wear, at the same time, is convenient for assembly and disassembly, improves the maintenance convenience and system modularization level. The structure is especially suitable for the running environment of the inner extraction yarn ball, can maintain the axial consistency of the split support ring during high-speed rotation and unwinding, ensure the stable support and smooth unwinding of the inner extraction yarn ball, and further improve the reliability and adaptability of the whole device.

[0037] In the embodiment, the groove width of the arc-shaped groove 12 matches the thickness size of the elastic limiting ring 13. The structural design ensures that the elastic limiting ring 13 can be accurately embedded in the grooves of the split support rings 6 formed by splicing, thereby realizing effective limiting and stable positioning of the whole split support ring.

[0038] By precisely matching the groove width with the thickness of the elastic limiting ring, the elastic limiting ring is prevented from loosening or shaking after installation, ensuring that it always remains in the designed position during high-speed rotation, tension changes or operation, and will not be caused to come off, deviate or vibrate unstably due to excessive structural fitting gap. The close fitting of the structure can also enhance the connecting force of the elastic limiting ring between each support ring segment, realize the coordinated movement between the split structure, and improve the rigidity and stability of the overall ring-shaped support assembly.

[0039] Meanwhile, the structural design facilitates assembly operation, and the elastic limiting ring can be smoothly inserted into the groove through elastic deformation during installation, and can also be quickly removed through elastic release during disassembly, without the need for additional tools, thereby improving the modular installation efficiency of the assembly and reducing maintenance costs. The precise fitting mode in combination with the elastic force buffering characteristics of the elastic limiting ring itself not only enhances the stability of the limiting function, but also further improves the reliability and adaptability of the pay-off support device during the operation of the load inner yarn package.

[0040] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
