AI Technical Summary
When the cradle device in existing steel cord double twisters rotates at high speed, the flywheel ring produces greater air resistance due to the contact between the flywheel ring and the air, resulting in greater rotational driving force, which affects the efficiency of the equipment and may lead to a decrease in the quality of the steel wire.
In the aluminum disc flywheel ring assembly of the cradle device, the number of flywheel rings is reduced from the two flywheel rings between the aluminum discs to 1. The two ends of the flywheel ring are fixed on the aluminum disc. Guide wire holes are provided in the flywheel ring to protect the core strand and the surface wire, and counterweights are provided on the aluminum disc to maintain dynamic balance.
By reducing the number of flywheel rings, components that are in contact with the air at high speed are reduced, thereby reducing air resistance, reducing rotational driving power, improving the energy saving efficiency of the equipment, and improving the production quality of steel wires.

Abstract
Description
Technical Field
[0001] The utility model relates to an improved structure of a cradle device used in a steel cord double-twisting machine, in particular to an improved structure of an aluminum disk flywheel ring component therein. Background Art
[0002] Steel cord is a product widely used in rubber skeleton materials, mainly used as skeleton materials for various tire rubber products; steel cord is generally made of two or more steel wires twisted into strands. The equipment for producing steel cord is mainly a steel cord double twist machine, which inputs the core strand and the surface strand into the twisting device together according to the structural characteristics of the steel cord, and then twists the strands to form the steel cord; to achieve twisting, a cradle device will be used, such as a multi-strand inner-release and outer-retracting double twist rope making machine with Chinese patent publication number CN216304286U, a four-pitch stranding machine that can realize continuous production with Chinese patent publication number CN201449817U, a twisting pair machine with Chinese patent publication number CN102412030B, a twelve-cradle device with Chinese patent publication number CN102587176B, and a twelve-cradle device with Chinese patent publication number CN202466269U.
[0003] There are several I-shaped wheels in the cradle device for wire protection; there are rotating aluminum discs at both ends of the cradle device, and two flywheel rings are connected between the two rotating aluminum discs. A group of core strands pass through one of the flywheel rings, and a group of surface strands pass through the other flywheel ring for output. The flywheel rings protect the output of the steel wire; the cradle device rotates at high speed, and the speed can generally reach more than 4500rpm, or even 6000rpm. The flywheel rings on both sides are symmetrically arranged, which can make the cradle device achieve stable dynamic balance.
[0004] Since the cradle device needs to maintain high-speed rotation, in order to reduce friction with the air, the aluminum discs at both ends are generally designed to be conical, and the flywheel ring is also designed to be flat. The aluminum disc is generally solid and has a small surface, so the friction resistance generated by contact with the air is small; however, the flywheel ring is a separate suspended component, which always cuts the air during rotation, so it will generate greater air resistance, so the drive device needs to output a larger rotational driving force to maintain the high-speed rotation of the cradle device.
[0005] In order to reduce the friction of the flywheel ring, some manufacturers have tried to cancel the flywheel ring, such as a steel wire double-twist internal pay-off cradle device with Chinese patent publication number CN104562817A, in which a wire guide wheel is directly set at the end of the rotating aluminum disk to pass the wire through the guide wheel; or a high-speed double-twist machine without a flywheel ring with Chinese patent publication number CN216514842U; but the problems caused by this are also significant. Due to the lack of a flywheel ring, the steel wire is directly in contact with the air, generating resistance, which affects the steel wire itself; at the same time, the steel wire is flexible, and as the cradle device rotates at a high speed, the steel wire is extended outward by the centrifugal force; therefore, the product quality is ultimately poor, and the cradle device can only be operated at a reduced speed, which reduces the operating efficiency of the equipment.
[0006] Therefore, in order to solve the above problems, the cradle device needs to be further improved and designed, especially the aluminum disc flywheel ring assembly therein needs to be improved and designed. Utility Model Content
[0007] The utility model aims to provide an aluminum disk flywheel ring assembly, a cradle device and a steel cord double twisting machine, which reduces the number of flywheel rings between aluminum disks to one, thereby reducing the number of parts in high-speed contact and friction with air, thereby reducing air resistance and achieving the purpose of energy saving.

[0011] There are two wire guide holes in the flywheel ring, which correspond to the core strand and the surface thread respectively.
[0012] As a further improvement of the utility model, one side of the aluminum plate protrudes to form a flywheel ring mounting protrusion, a mounting groove is provided on the inner side of the flywheel ring mounting protrusion, and one end of the flywheel ring is embedded in the mounting groove;
[0013] The pressure plate presses and fixes one end of the flywheel ring in the installation protrusion of the flywheel ring through a fastener.
[0014] As a further improvement of the utility model, a threading hole is provided at the installation position of the flywheel ring of the aluminum disk, and the threading hole is connected with the wire guide hole in the flywheel ring, and two threading holes are provided.
[0015] Furthermore, a wire guide sleeve is embedded in the wire passing hole, and the wire guide sleeve is connected to the wire guide hole in the flywheel ring.
[0016] As a further improvement of the utility model, a counterweight block is provided on the side of the aluminum plate away from the flywheel ring.
[0017] Furthermore, the counterweight block is integrally processed with the aluminum plate.
[0018] Furthermore, the counterweight block is an independent steel component, the counterweight block is embedded in the aluminum plate, and the counterweight block is fixed in the aluminum plate by fasteners.
[0019] A second aspect of the utility model provides a cradle device, comprising two aluminum plates and a flywheel ring;
[0020] Two aluminum discs and one flywheel ring form the aluminum disc flywheel ring assembly as described above, and rotate synchronously at high speed.
[0021] The third aspect of the utility model provides a steel cord double twisting machine, which is provided with a cradle device of an aluminum disk flywheel ring assembly composed of two aluminum disks and a flywheel ring as described above.
[0022] The aluminum disk flywheel ring assembly of the utility model reduces the number of flywheel rings between the aluminum disks to one, thereby reducing the number of components in high-speed contact and friction with air, further reducing air resistance, and achieving the purpose of energy saving.
[0023] Therefore, during the operation of the steel cord double-twisting machine, the rotational driving power of the driving cradle device is lower, which is more energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0032] The utility model relates to a structural improvement of a cradle device in a steel cord double twisting machine, in particular to a structural improvement of an aluminum disk flywheel ring assembly; the aluminum disk flywheel ring assembly of the utility model has an overall structure as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; aluminum plates 1 are provided on both sides of the cradle device, and the two aluminum plates 1 are coaxially arranged to rotate at high speed.
[0033] The improvement of the utility model is that only one flywheel ring 2 is arranged between the two aluminum plates 1, and the two ends of the flywheel ring 2 are respectively fixed on the two aluminum plates 1, and the flywheel ring 2 rotates synchronously with the two aluminum plates 1 at a high speed;
[0034] Two wire guide holes are arranged in the flywheel ring 2, corresponding to the core strand and the surface thread passing through respectively.
[0035] Further Figure 5 , Figure 6 As shown; one side of the aluminum plate 1 protrudes to form a flywheel ring mounting protrusion 11, and a mounting groove 111 is provided on the inner side of the flywheel ring mounting protrusion 11, and one end of the flywheel ring 2 is embedded in the mounting groove 111, and the pressure plate 13 presses and fixes one end of the flywheel ring 2 in the flywheel ring mounting protrusion 11 through a fastener; because the flywheel ring 2 is installed on the inner side of the flywheel ring mounting protrusion 11 of the aluminum plate 1, when the aluminum plate 1 and the flywheel ring 2 rotate at high speed, the centrifugal force generated by the flywheel ring 2 is fully borne by the flywheel ring mounting protrusion 11, which is not easy to cause the pressure plate 13 to detach, and the installation is more reliable. In addition, there is no protrusion on the outer side of the aluminum plate 1, and the air friction resistance during high-speed rotation is also smaller.
[0036] A wire hole 12 is provided at the installation position of the flywheel ring 2 of the aluminum plate 1, and the wire hole 12 is connected with the wire guide hole in the flywheel ring 2, and two wire holes 12 are also provided. Further, a wire guide sleeve 21 is embedded in the wire hole 12. Since the material of the aluminum plate 1 is aluminum alloy, which is not wear-resistant, the wear-resistant wire guide sleeve 21 is lined in the wire hole 12, which can improve the service life and can be replaced independently.
[0037] Furthermore, in order to achieve dynamic balance of the aluminum plate 1 during high-speed rotation, a counterweight block 3 is provided on the side of the aluminum plate 1 away from the flywheel ring 2. The counterweight block 3 can be a convex block integrally processed with the aluminum plate 1, or can be Figure 7 As shown, the counterweight block 3 is an independent component, especially a steel component, which can obtain a larger counterweight with a smaller volume, and is embedded in the aluminum plate 1 and fixed by fasteners.
[0038] The aluminum disk flywheel ring assembly of the utility model reduces the flywheel ring 2 between the aluminum disks 1 to one, thereby reducing the parts that come into contact and rub against the air at high speed, thereby reducing the air resistance and achieving the purpose of energy saving. According to calculations, it is expected that the rotation drive power of the cradle device can be reduced by 1-2kw.
