Description

Technical Field

[0001] This utility model relates to the field of steel cord technology, and in particular to a steel cord anti-detachment winding shaft and I-beam reel. Background Technology

[0002] The invention of the automobile is undoubtedly an important symbol of human civilization's progress. As the only part of the automobile that comes into direct contact with the ground, the quality of the tires directly affects whether the automobile can realize the value of its invention. Today, rubber tires with built-in steel cords are widely used in various vehicles and machinery.

[0003] As a key structural material for tires, steel cord relies on I-beam spools for its production, handling, and packaging. However, the winding shafts currently used with I-beam spools generally have a circular cross-section design. The smooth, round surface lacks edge support, and the steel cord is fixed solely by its own winding force during winding, lacking additional pre-stress tension restraint.

[0004] Therefore, during transportation, the steel cords are easily loosened by external forces such as bumps and vibrations, which can lead to problems such as falling off and scattering. This not only requires additional sorting of the steel cords before subsequent use, increasing labor costs, but may also cause damage to the steel cords due to friction and compression during the scattering process, affecting their mechanical properties and ultimately having an adverse impact on the tire's load-bearing, traction, and safety performance. Utility Model Content

[0005] The main purpose of this utility model is to provide a steel cord anti-detachment winding shaft and I-beam reel. The cross-section of the winding shaft body along the length direction is set as a regular polygon, and its corners can exert a squeezing effect on the wound steel cord, so that the steel cord obtains prestress tension and is tightly bound to the outside of the shaft body. This can prevent the steel cord from falling off or scattering during transportation, and ensure that the steel cord remains neat after transportation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A steel cord anti-detachment winding shaft includes a shaft body, a through hole on one side of the shaft body, and the cross-section of the shaft body in the length direction is a regular polygon.

[0007] Furthermore, the cross-section of the shaft along its length is a regular hexagon.

[0008] Furthermore, the shaft is made of nylon material.

[0009] This utility model also discloses an H-beam wheel, including a shaft body, with fixed discs on both sides of the shaft body, and a positioning hole matching the through hole on one side of the fixed disc.

[0010] Furthermore, a number of pins are fixed on one side of the fixed plate, and insertion holes matching the pins are respectively opened on both sides of the shaft.

[0011] Furthermore, one of the fixed discs has a slot on its side away from the shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The cross-section of the winding shaft of this utility model is set as a regular polygon along its length direction. Its corners can exert a squeezing effect on the wound steel cord, so that the steel cord can obtain prestress tension and be tightly bound to the outer periphery of the shaft. This can prevent the steel cord from falling off or scattering during transportation, and ensure that the steel cord can remain neat after transportation.

[0013] 2. The shaft of this utility model is made of nylon material, which has the advantages of being drop-resistant, rust-proof, and not easily deformed. It can resist the effects of physical collisions and environmental corrosion during the production and use of steel cord, reduce the frequency of shaft damage, meet the usage needs of steel cord production scenarios for a long time, and reduce replacement costs.

[0014] 3. The I-beam wheel of this utility model achieves a fixed connection between the shaft and the fixed plate through pins, holes and adhesive bonding, thus avoiding loosening during assembly. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1 As shown, a steel cord anti-detachment winding shaft and I-beam wheel include a shaft body 1, a through hole 101 on one side of the shaft body 1, and the cross section of the shaft body 1 in the length direction is a regular polygon.

[0025] In this embodiment, the cross-section of the shaft 1 along its length is a regular hexagon with an interior angle of 158 degrees and an exterior included angle of 23 degrees, which is close to a circle. When the steel cord is wound around the outside of the shaft 1, the steel cord will have a certain prestress tension due to the edges and corners of the shaft 1, thus tightly binding it to the outside of the shaft 1, achieving a good anti-loosening effect and preventing the steel cord from becoming loose during transportation.

[0026] Among them, shaft 1 is made of PA66 nylon material, which has the advantages of being drop-resistant, rust-proof, and not easily deformed, and can meet the needs of steel cord production and use.

[0027] This utility model also discloses an H-beam wheel, such as Figure 2 and Figure 3As shown, it includes a shaft body 1, with fixed disks 2 on both sides of the shaft body 1. A positioning hole 202 matching the through hole 101 is opened on one side of the fixed disk 2. The positioning hole 202 and the through hole 101 have the same diameter. After the shaft body 1 and the fixed disk 2 are connected, an I-beam wheel is formed. In use, the rotating shaft of the rotating device can be inserted into the positioning hole 202 and the through hole 101, thereby driving the I-beam wheel to rotate and realize the winding operation of steel cord.

[0028] Specifically, such as Figure 3 As shown, a number of pins 203 are fixed on one side of the fixed plate 2, and insertion holes 204 matching the pins 203 are respectively opened on both sides of the shaft body 1. After the pins 203 are inserted into the insertion holes 204, the fixed plate 2 is fixed to the shaft body 1 by the friction between the two. The pins 203 can also be completely glued and fixed in the insertion holes 204 by glue. Furthermore, when the I-beam wheel is installed on the rotating device, the rotating shaft of the rotating device extends through the through hole 101 and the positioning hole 202, and the end of the extension is threaded with a locking structure, thereby clamping and fixing the I-beam wheel on the rotating shaft of the rotating device.

[0029] The fixing plate 2 and the shaft 1 can also be injection molded as a whole.

[0030] Among them, such as Figure 2 and Figure 3 As shown, one of the fixed discs 2 has a slot 201 on its side away from the shaft 1, such as... Figure 4 As shown, the buckle on the chuck on the rotating shaft of the rotating device can be engaged in the slot 201, thereby ensuring that the rotating shaft of the rotating device rotates synchronously with the I-beam wheel.

[0031] Working principle: The cross-section of the shaft 1 along its length is a regular hexagon, which is nearly circular but retains its corner features. When the steel cord is wound around the outer perimeter of the shaft 1, the corners of the shaft 1 will exert a squeezing effect on the steel cord, giving the steel cord a certain prestress tension. This tension allows the steel cord to be tightly bound to the outer perimeter of the shaft 1, effectively preventing the steel cord from falling off or scattering due to loosening during transportation.

[0032] The I-beam wheel consists of a shaft body 1 and two fixed discs 2 on both sides. Several pins 203 are fixed on one side of the fixed disc 2. The two sides of the shaft body 1 are respectively opened with insertion holes 204 that match the pins 203. After the pins 203 are inserted into the insertion holes 204, they are initially fixed by the friction between the two. In order to further improve the connection firmness, the pins 203 can be completely glued and fixed in the insertion holes 204 by glue, and finally assembled to form the I-beam wheel.

[0033] In use, the rotating shaft of the rotating device is inserted into the positioning hole 202 of the fixed plate 2 and the through hole 101 of the shaft body 1 in sequence. The end of the rotating shaft extending out of the through hole 101 adopts a threaded connection locking structure. Through the clamping action of the locking structure, the I-beam wheel is stably clamped and fixed on the rotating shaft of the rotating device, preventing the I-beam wheel from shifting along the axial direction of the rotating shaft during rotation. In addition, a slot 201 is provided on the side of one of the fixed plates 2 away from the shaft body 1. The chuck on the rotating shaft of the rotating device is provided with a buckle. The buckle is inserted into the slot 201 to ensure the synchronous rotation of the rotating shaft of the rotating device and the I-beam wheel.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
