Description

Technical Field

[0001] The utility model relates to an aluminum disk flywheel ring component used in a cradle device of a steel cord double twisting machine. 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.

[0007] For the cradle device in the existing steel cord double twisting machine, it is also necessary to provide an improved structure involving the aluminum disk flywheel ring assembly in order to reduce the operating energy consumption and achieve the purpose of energy saving.

[0008] The utility model aims to provide an aluminum disk flywheel ring assembly for a steel cord double-twisting machine, improves the aluminum disk structure, and then only installs one flywheel ring between the aluminum disks on both sides, and two channels are arranged in the flywheel ring, which respectively pass through the core strand and the surface wire; by reducing one flywheel ring, the number of parts in high-speed contact and friction with the air is reduced, thereby reducing the air resistance and achieving the purpose of energy saving.

[0009] In order to achieve the above-mentioned utility model object, the utility model provides an aluminum disk flywheel ring assembly for a steel cord double twisting machine, comprising two aluminum disks and one flywheel ring; only one flywheel ring is arranged between the two aluminum disks;

[0010] The mounting protrusions on the aluminum plate are processed to form mounting grooves, which match the size of the flywheel ring;

[0011] The mounting groove is located on the outside of the mounting protrusion of the aluminum plate;

[0012] The two ends of the flywheel ring are respectively embedded in the mounting grooves of the aluminum disk, and the flywheel ring rotates synchronously with the two aluminum disks at high speed;

[0013] A pressing plate is installed on the installation groove by fasteners, and the pressing plate presses and fixes the end of the flywheel ring in the installation groove of the aluminum plate;

[0014] There are two wire guide holes in the flywheel ring, corresponding to the core strand and the surface thread;

[0015] A counterweight is arranged on one side of the aluminum plate away from the flywheel ring.

[0016] As a further improvement of the utility model, more than two pressing plates are provided; fasteners are provided on both sides of each pressing plate.

[0017] As a further improvement of the utility model, a wire guide block is embedded in the installation groove;

[0018] There are two wire guide holes on the wire guide block, and wear-resistant wire guide sleeves are embedded in the wire guide holes;

[0019] The wire-passing hole and the wire-guiding sleeve therein are respectively connected with two wire-guiding holes in the flywheel ring.

[0020] As a further improvement of the present invention, the counterweight is an independent steel component;

[0021] The counterweight is fixed to the aluminum plate by fasteners.

[0022] The aluminum disk flywheel ring assembly for the steel cord double twisting machine of the utility model reduces the flywheel ring between the aluminum disks to one, thereby reducing the parts in high-speed contact and friction with the air, 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.

[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

[0032] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0033] The utility model relates to an aluminum disk flywheel ring assembly for a steel cord double twisting machine, which is installed in a cradle device of the steel cord double twisting machine. The overall structure is 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. The improvement of the utility model is that only one flywheel ring 2 is provided 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 high speed; two wire guide holes are provided in the flywheel ring 2, which correspond to the core strand and the surface thread passing through respectively.

[0034] The utility model is used as an improvement on the cradle device in the existing steel cord double-twist machine, that is, the original two flywheel rings are removed, and then the aluminum plate 1 is properly processed, especially the mounting protrusion 11 on the aluminum plate 1 is processed to form a mounting groove 12, and the mounting groove 12 matches the size of the flywheel ring 2; the mounting groove 12 is located on the outside of the mounting protrusion 11 of the aluminum plate 1, which is convenient for disassembly and assembly; one end of the flywheel ring 2 is embedded in the mounting groove 12; a pressure plate 13 is installed on the mounting groove 12 with fasteners, and the pressure plate 13 is preferably provided with two, and the end of the flywheel ring 2 is pressed at multiple points to fully fix the flywheel ring 2 on the aluminum plate 1; because the mounting groove 12 is located on the outside, during the high-speed rotation of the aluminum plate 1, the centrifugal force generated by the flywheel ring 2 will act on the pressure plate 13, so it is necessary to fully reinforce the pressure plate 13 to avoid disengagement during high-speed rotation. Figure 5 , Figure 6 shown.

[0035] Furthermore, a wire guide block 21 is embedded in the installation groove 12, and two wire holes 22 are opened on the wire guide block 21. Wear-resistant wire guide sleeves are embedded in the wire holes 22, which are generally made of alloy materials, can improve the service life, and can be replaced independently; the wire holes 22 and the wire guide sleeves located therein are connected with the two wire guide holes in the flywheel ring 2. If the steel wire is directly inserted into the wire guide hole of the flywheel ring 2, it is easy to generate friction at the end, causing wear of the flywheel ring 2, so it is necessary to line it with a wire guide sleeve, and correspondingly, a special wire guide block 21 needs to be set to install and fix the wire guide sleeve; the wire guide block 21 is fixed in the installation groove 12 of the aluminum plate 1 by fasteners, and the wire guide block 21 is installed close to the end of the flywheel ring 2.

[0036] Furthermore, in order to achieve dynamic balance of the aluminum plate 1 during high-speed rotation, a counterweight 3 is provided on the side of the aluminum plate 1 away from the flywheel ring 2. Figure 8 As shown, the counterweight block 3 is an independent component, especially a steel component, which can obtain a larger counterweight with a smaller volume; the counterweight block 3 is fixed to the aluminum plate 1 by fasteners.

[0037] The aluminum disk flywheel ring assembly for the steel cord double twisting machine of the utility model reduces the flywheel ring 2 between the aluminum disks 1 to one, thereby reducing the parts in high-speed contact and friction with the air, 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.
