In the accompanying drawings, each identical or nearly identical component shown in various figures may be represented by the same reference numeral. For the sake of clarity, not every component is labeled in every figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, in which:

[0018] Figure 1 This is a schematic structural diagram of a pay-off stand for twisting steel cords shown in the present invention;

[0019] Figure 2 It is a schematic diagram of the steel wire being wound between the guide wheel group and the pay-off wheel group shown in the present invention. DETAILED DESCRIPTION

[0020] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0021] Combine Figure 1 As shown, the first aspect of the present invention provides a pay-off stand for twisting steel cord, comprising at least one base 10, which is arranged outside the stranding equipment and has a plurality of swivel seats 11 for loading spools.

[0022] In this way, the I-spool is not restricted by the volume of the twisting equipment. By flexibly setting the number of I-spools, different twisting requirements can be met. For example, the maximum capacity of the base 10 is to place eight I-spools. When twisting eight or fewer strands of steel cord, one base 10 can be used. If twisting more than eight strands of steel cord, different numbers of bases 10 can be combined as needed. When twisting 15 strands of steel cord, two bases 10 are used.

[0023] Combine Figure 1 As shown, the base 10 is further provided with a plurality of guide arms 14 distributed corresponding to the swivel seat 11 and a pay-off arm 15 , the guide arm 14 is provided with a guide wheel set 20 , and the pay-off arm 15 is provided with a pay-off wheel set 30 .

[0024] Among them, the pay-off wheel group 30 includes multiple pay-off wheels, and the guide wheel group 20 includes a first guide wheel 21 and a second guide wheel 22. The axis of the first guide wheel 21 is arranged along the first direction, and the axis direction of the second guide wheel 22 is arranged along the second direction. The first direction is perpendicular to the second direction, and the top of the wire groove of the first guide wheel 21 is at the same height as the wire groove of the second guide wheel 22.

[0025] In this way, when the I-shaped wheel on the rotating seat 11 pays off the wire, the steel wire on the surface of the I-shaped wheel passes around the first guide wheel 21, the second guide wheel 22 and the pay-off wheel in sequence. The steel wire is smoothly transitioned through multiple guide wheels and pay-off wheels, making the pay-off smooth.

[0026] Furthermore, the multiple pay-off wheels are arranged in a straight line, so that the multiple steel wires wound off the pay-off wheels enter the stranding device parallel to each other within a predetermined area for twisting. In this way, when the steel wires enter the stranding device from the pay-off frame, they are relatively concentrated, which is conducive to being twisted into strands in the stranding device.

[0027] Combine Figure 1 As shown, at least two support columns 12 are provided on the base 10 , and a connecting rod 13 is provided at the upper end of the support column 12 , and the guide arm 14 and the pay-off arm 15 are both connected to the connecting rod 13 .

[0028] Among them, a plurality of guide arms 14 are arranged on the left and right sides of the connecting rod 13 , and the pay-off arm 15 is arranged at the front end of the connecting rod 13 .

[0029] Optionally, multiple swivel seats 11 are divided into a first group on the first side of the support column 12 and a second group on the second side of the support column 12, and multiple guide arms 14 are also divided into a first group on the first side of the connecting rod 13 and a second group on the second side of the connecting rod 13.

[0030] In this way, multiple swivel seats 11 are divided into two groups, each group is arranged longitudinally with a compact structure. Through multiple pay-off wheels on the pay-off arm 15 at the front end of the connecting rod 13, each steel wire is guided in the direction of entry before entering the stranding equipment.

[0031] Further, the number of the wire grooves on the surfaces of the multiple pay-off wheels is greater than or equal to the number of the swivels 11. Each steel wire wound out of the spool is introduced into the stranding device through the wire grooves on the surface of the pay-off wheel.

[0032] In an optional embodiment, the pay-off wheel includes two line-passing grooves arranged one above the other, and the guide wheel group 20 is divided into a large guide wheel group and a small guide wheel group.

[0033] Combine Figure 2 As shown, specifically, the base 10 has a total of eight swivel seats 11, the pay-off arm 15 is provided with four double-groove pay-off wheels, and the connecting rod 13 is provided with eight guide wheel groups, which are divided into four large guide wheel groups and four small guide wheel groups.

[0034] Taking the guide wheel group on one side as an example, the large guide wheel group is divided into two groups, namely the first guide wheel a21a, the second guide wheel a22a and the first guide wheel c21c, the second guide wheel c22c; the small guide wheel group is also divided into two groups, namely the first guide wheel b21b, the second guide wheel b22b and the first guide wheel d21d, the second guide wheel d22d.

[0035] It should be understood that the height of the wire groove of the second guide wheel a22a and the second guide wheel c22c is the same as the height of the wire groove above the pay-off wheel, and the height of the wire groove of the second guide wheel b22b and the second guide wheel d22d is the same as the height of the wire groove below the pay-off wheel.

[0036] In this way, the steel wire wound around the second guide wheel a22a and the second guide wheel c22c can be smoothly wound into the wire groove above the pay-off wheel without any up and down deflection, and the steel wire wound around the second guide wheel b22b and the second guide wheel d22d can be smoothly wound into the wire groove below the pay-off wheel without any up and down deflection.

[0037] Furthermore, the axial heights of the first guide wheel a21a, the first guide wheel b21b, the first guide wheel c21c and the first guide wheel d21d are the same. In order to allow the steel wire to smoothly transition when passing around the first guide wheel and the second guide wheel, the top of the first guide wheel corresponds to the height of the wire groove of the second guide wheel. Therefore, the diameter of the first guide wheel a21a is larger than the diameter of the first guide wheel b21b, and the diameter of the first guide wheel c21c is larger than the diameter of the first guide wheel d21d.

[0038] In the above embodiment, a wire clamp (not shown in the figure) is provided on one side of the first guide wheel 21. During the wire changing operation, the wire end led out of the I-wheel can be clamped by the wire clamp.

[0039] In combination with the above embodiments, the pay-off stand proposed by the utility model places the I-wheel outside, and all the I-wheels are finally concentrated on the take-up port of the stranding equipment through the guide wheel group of the pay-off stand to pay out the wire. The wire routing is smooth, and the number of I-wheels can be increased or decreased according to different twisting requirements to flexibly adapt to different production needs. At the same time, the swivel seat can be replaced and used according to different I-wheel apertures to adapt to different I-wheels, thereby solving the limitations of existing equipment on the number and types of pay-off I-wheels.

[0040] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
