Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, and particularly relates to a tension belt for steel wire pay-off. Background Art

[0002] In the production process of steel cord, the most basic requirement is the pay-off tension. In order to achieve higher production efficiency, the general single wire wheel has a single wire tens of thousands of meters long. It is necessary to ensure the stable operation of the single wire to the rope forming port and also ensure that the tension difference between the wheel surface and the wheel bottom is not too large. Under such a premise, higher requirements are put forward for the tension pay-off system of steel cord equipment.

[0003] Tension control directly affects key indicators such as the wire diameter, strength, hardness, and shape of the steel cord. Appropriate tension can ensure the stability of the steel cord during the production process, avoid problems such as wire diameter changes, curling, or sagging caused by insufficient tension, thereby ensuring the high quality of the product. Through precise tension control, the downtime and rework rate during the production process can be reduced, the production cost can be lowered, and the production efficiency can be improved.

[0004] The most important part of the pay-off tension system is the tension belt. By controlling the contact pressure between the tension belt and the pay-off shaft / disc, different tensions can be achieved on the pay-off wheel. Currently used nylon tension belts or Teflon steel tension belts have various problems such as easy wear and high-temperature deformation damage during long-term operation.

[0005] Therefore, how to make the tension belt have sufficient wear resistance and heat resistance is the problem to be solved in this application. Summary of the Utility Model

The first surface and the second surface are two opposite side surfaces, and the first surface and the second surface are configured as arc surfaces with the same radian;

[0010] Wherein, the first surfaces of a plurality of friction blocks together form a first friction surface, and the second surfaces of a plurality of friction blocks together form a second friction surface.

For clarity, not every component is labeled in each figure. Now, embodiments of various aspects of the present utility model will be described by way of examples and with reference to the drawings, wherein:

[0024] Figure 2 It is a schematic diagram of the tension belt for wire pay - out shown in the present utility model attached to the surface of the pay - out shaft / disc;

[0025] Figure 3 It is a schematic structural diagram of the friction block shown in the present utility model. Specific embodiments

[0026] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0027] As Figure 1 shown, in the first aspect of the present utility model, a tension belt for wire pay - out is proposed, which includes a wire support structure 10 and a plurality of friction blocks 20. The wire support structure 10 includes an anchoring end 11 and a control end 12. The anchoring end 11 of the wire support structure 10 is fixed at a preset position, and the control end 12 of the wire support structure 10 is connected to a tension control mechanism.

[0028] For example Figure 2 shown, the anchoring end 11 of the wire support structure 10 can be connected to a fixed structure on one side of the pay - out shaft / disc 30, and the control end 12 of the wire support structure 10 is connected to a tension control mechanism, such as a telescopic mechanism. By adjusting the position of the control end 12, a certain contact pressure is maintained between the plurality of friction blocks 20 and the pay - out shaft / disc 30, thereby controlling the pay - out tension of the pay - out shaft / disc 30.

[0029] A plurality of friction blocks 20 are connected to the wire support structure 10, and each friction block 20 has a fixed position relative to the wire support structure 10. In this way, the pay - out tension is controlled by the damping formed by the contact between the plurality of friction blocks 20 and the surface of the pay - out shaft / disc. The plurality of friction blocks 20 can provide effective and reliable friction, which is suitable for providing friction for a long time and continuously.

[0030] Furthermore, the friction block 20 is configured to include a first surface 21 and a second surface 22. Grooves 24 are provided on the surfaces of the first surface 21 and the second surface 22. The first surface 21 and the second surface 22 are two opposite side surfaces, and the first surface 21 and the second surface 22 are configured as arc surfaces with the same radian;

[0031] Among them, the first surfaces 21 of the plurality of friction blocks 20 together form a first friction surface 201, and the second surfaces 22 of the plurality of friction blocks 20 together form a second friction surface 202.

[0032] Thus, a tension band can provide two friction surfaces, namely a first friction surface 201 and a second friction surface 202. The parameters of the two friction surfaces are the same and can be used for the tension control of the same pay-off spool / drum. When the tension control performance of the first friction surface 201 for the current pay-off spool / drum deteriorates, the second friction surface 202 can be replaced to control the tension of the current pay-off spool / drum. The service life of a tension band is much longer than that of the current tension band.

[0033] Furthermore, the steel wire includes a stranded steel wire bundle. The main body of the steel wire support structure 10 of the tension band is a stranded steel wire, which has good flexibility and high strength. Different numbers of friction blocks 20 and corresponding spacings can be set according to the diameter of the pay-off spool / drum, so that each friction block 20 closely adheres to the surface of the pay-off spool / drum. Thus, effective tension control can be provided.

[0034] Furthermore, as Figure 3 shown, the friction block 20 is configured as a hexahedron structure, including two end faces, a pair of arc-shaped side faces and a pair of flat side faces. A perforation 25 is provided on the end face 23 of the friction block 20, and the perforation 25 penetrates through the two end faces 23 of the friction block 20.

[0035] Thus, after a plurality of friction blocks 20 connected in series to the steel wire support structure 10 are attached to the pay-off spool / drum with their first arc surfaces, they can maintain the stability of the position state and will not shift or roll.

[0036] In an alternative embodiment, the steel wire support structure 10 includes a steel wire, and the steel wire passes through the perforation 25.

[0037] In other embodiments, the steel wire support structure 10 includes more than one steel wire, such as two or three parallel steel wires. The steel wire passes through the perforation 25. The arrangement direction of the steel wires is defined as the first direction, and the flat side face is perpendicular to the first direction.

[0038] Thus, positioning of the friction block 20 is achieved by more than two steel wires, so that the arc surface of the friction block 20 closely adheres to the surface of the pay-off spool / drum, that is, there is no skew and no local uneven friction occurs.

[0039] In an alternative embodiment, the perforation 25 is filled with an adhesive structure, and the steel wire support structure 10 is fixed in the perforation 25 through the adhesive structure. Optionally, the adhesive structure is a thermosetting adhesive.

[0040] Furthermore, the groove 24 is configured to extend along the length direction of the friction block 20, and the depth is less than half of the friction block 20. Thus, by constructing the groove 24 on the first surface 21 and the second surface 22, a heat dissipation groove can be formed. When the friction block 20 continuously contacts the pay-off spool / drum, effective heat dissipation can be provided to avoid too high surface temperature of the first surface 21 or the second surface 22.

[0041] Preferably, the bottom surface of the groove 24 is a flat surface. In this way, the groove 24 can be used as a scale, that is, visually represent the wear depth of the first surface 21 or the second surface 22. When worn to a predetermined thickness, the other surface is replaced as the friction surface for use.

[0042] Optionally, the grooves 24 provided on the first surface 21 and the second surface 22 have the same depth.

[0043] Furthermore, in order to maintain a relatively large friction area, there are no more than two grooves 24 on the surfaces of the first surface 21 and the second surface 22.

[0044] Combined with the above embodiments, the tension belt proposed by the present utility model takes a steel wire rope as the main body and is equipped with a plurality of friction blocks. The steel wire rope ensures the durability of the tension belt, is not easy to break, and has great plasticity. Due to its good flexibility, it can reasonably arrange the length of the tension belt and the number of friction blocks according to the size of different wire reels. The wear-resistant blocks on the steel wire rope body serve as tension friction components. The width of the tension blocks fits the wire-reeling friction disc, and both the front and back are designed as arc-shaped surfaces for convenient use in both directions. The steel wire rope passes through the center of the friction block and is fixed with high-temperature resistant strong glue. Compared with the existing tension belt, it has better wear resistance, service life, and tension stability.

Those with ordinary knowledge in the technical field to which the present utility model belongs can make various modifications and refinements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to what is defined by the claims.
