During the production process, it needs to be twisted by a twisting device. The twister is a link in the twisting equipment, which is mainly used to pre-twist or untwist the steel wire. For example, a steel cord twisting system disclosed in patent No. CN116289278A comprises: a first rotatable flywheel portion, the first flywheel portion is used to simultaneously release more than two outer windings and twist them into a whole outer winding bundle; a first twister is arranged at the rear side of the first flywheel portion, the outer winding bundle passes through the first twister and is reversely twisted into a single outer winding; a second rotatable flywheel portion is arranged at the rear side of the first twister, the second flywheel portion is used to release a single core wire and simultaneously twist the core wire with the outer winding from the first twister to obtain a steel cord. However, the two wire wheels in this type of twister are staggered, that is, the two are staggered from the axis of rotation of the twister. This structure makes the twister work only at a certain speed and cannot achieve high speed operation, affecting production efficiency and twisting effect. Utility Model Content

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1-Figure 4 As shown, the twisting device for steel cord twisting equipment provided in this embodiment is used in combination with the steel cord twisting equipment to pre-twist or untwist the steel wire, which mainly includes a box 10, a fixed seat 20 arranged in the box 10, a rotating seat 30 rotatably arranged on the fixed seat 20, two wire passing wheel groups 40 arranged on the rotating seat 30, and a driving motor 50 arranged in the box 10. The steel wire 100 passes through one side of the box 10, passes through the fixed seat 20, the rotating seat 30 and the wire passing wheel group 40, and then passes through the other side of the box 10. The rotating seat 30 is driven by the driving motor 50 to rotate, and then the steel wire 100 is twisted.

[0029] The box body 10 has an openable upper cover to open and close the internal space of the box body 10. During normal operation, the upper cover is in a closed state to avoid external interference. When maintenance or wire installation operations are required, the upper cover can be opened.

[0030] In addition, both ends of the rotating seat 30 are connected to the fixed seat 20 through the rotating shaft 301, and the driving motor 50 is used to drive the rotating shaft 301 to rotate, and the center lines of the two wire-passing wheel groups 40 are located in the same plane, and the rotating axis 301 line of the rotating shaft 301 is located in the plane where the center lines of the two wire-passing wheel groups 40 are located, that is, the coincidence points of the three are located on the same straight line.

[0031] In addition, a first synchronous wheel 61 is provided on one side of the rotating shaft 301, and the first synchronous wheel 61 is located on the outside of the fixed seat 20. The output shaft of the driving motor 50 is provided with a second synchronous wheel 62. A synchronous belt 63 is provided between the first synchronous wheel 61 and the second synchronous wheel 62, and rotational drive is realized through the structure of the synchronous belt and the synchronous wheel.

[0032] The fixed seat 20 includes a fixed bottom plate 21 and fixed side plates 22 arranged at both ends of the fixed bottom plate 21 . Both ends of the rotating seat 30 are connected to the fixed side plates 22 via a rotating shaft 301 . There is a distance between the rotating seat 30 and the fixed bottom plate 21 .

[0033] Also, considering that the internal space of the box body 10 is deep and partially blocked by the upper cover, resulting in a poor internal field of vision, the operator is usually required to hold a flashlight for lighting. Therefore, a receiving groove is provided on the fixed bottom plate 21, and a light-emitting lamp body is provided in the receiving groove. The upper cover of the receiving groove is provided with a transparent cover 211, and the lighting function is realized by the light-emitting lamp body. The upper end surface of the cover 211 is flush with the upper end surface of the fixed bottom plate 21, and can also be lower than the upper end surface of the fixed bottom plate 21 to avoid interfering with the rotational movement of the rotating seat 30.

[0034] Furthermore, the rotating seat 30 includes a rotating bottom plate 31 and rotating side plates 32 disposed at two ends of the rotating bottom plate 31 , and the rotating shaft 301 is disposed outside the rotating side plates 32 .

[0035] In addition, the wire passing wheel assembly 40 includes a wire passing wheel body 41, a limit cover 42 and a locking piece 43. The limit cover 42 is arranged at the upper end of the wire passing wheel body 41, and the locking piece 43 passes through the limit cover 42 and penetrates into the wire passing wheel body 41. The wire passing wheel body 41 is surrounded by a plurality of circles of wire passing grooves 411. The wire passing wheel body 41 is sleeved on a fixed shaft located on the rotating base plate 31, and the limit cover 42 covers the upper end of the wire passing wheel body 41. The locking piece 43 passes through the limit cover 42 and is screwed into the fixed shaft, so that the limit cover 42 can be limited above the wire passing wheel body 41, thereby limiting the wire passing wheel body 41 from falling off. The locking piece 43 can be a bolt or other structure.
