[0005] Base;

[0006] Stranding hook, which is rotatably connected with the base, the stranding hook includes a rotating shaft portion and a rotating hook portion, and the rotating hook portion is connected with the rotating shaft portion.

[0007] Drive assembly, including a rotating drive element and a transmission shaft, the rotating drive element is connected with the transmission shaft, the rotating drive element can drive the transmission shaft to rotate, the transmission shaft is eccentrically connected with the rotating shaft portion, and the rotating drive element drives the stranding hook to rotate through the transmission shaft.

[0008] In the above-mentioned eccentric stranding mechanism, a first transmission chain and a first gear are further included, one end of the first transmission chain is engaged with the output portion of the rotating drive element, and the other end of the first transmission chain is engaged with the first gear.

[0009] In the above-mentioned eccentric stranding mechanism, the number of the transmission shaft and the first gear is two, and a first adjusting gear is further included, the first adjusting gear is rotatably connected with the base, the first transmission chain is sequentially engaged with the output shaft of the rotating drive element, one of the first gears, the first adjusting gear, and the other first gear, and finally returns to the output shaft of the rotating drive element to form a closed loop.

[0010] In the aforementioned eccentric stranding mechanism, an adjusting plate is also included. The first adjusting gear and the rotation driving element are both connected to the adjusting plate, and the adjusting plate is slidably connected to the base.

[0011] In the aforementioned eccentric stranded wire mechanism, a fastener is also included. The adjusting plate is provided with a first guide hole and a receiving groove. The drive shaft is accommodated in the receiving groove and can slide within the receiving groove. The fastener passes through the first guide hole and is connected to the base. The fastener can slide within the first guide hole.

[0012] In the aforementioned eccentric stranding mechanism, a second transmission chain is also included, and the transmission shaft is further provided with a second gear. The number of transmission shafts is at least four, and in the vertical direction, two of the transmission shafts are connected to each other by the second transmission chain and two of the second gears.

[0013] In the aforementioned eccentric stranded wire mechanism, a second adjusting gear is further included. The second adjusting gear is slidably connected to the base and meshes with the second transmission chain.

[0016] In the aforementioned eccentric stranding mechanism, the rotating shaft is provided with a first inclined surface, the transmission shaft is provided with a second inclined surface, and the first inclined surface is in contact with the second inclined surface.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Traditional stranding hooks typically rotate around a fixed central axis, meaning the center knot position of the material needs constant adjustment to ensure uniform winding. However, this adjustment often leads to additional friction and resistance, reducing stranding efficiency and potentially causing unnecessary stress on the material. In contrast, stranding hooks employing an eccentric rotation mechanism do not have a fixed rotation center; instead, they move along a predetermined eccentric path. This allows the center knot position of the material to remain relatively stable without frequent large-scale offsets. Consequently, the contact between the stranding hook and the processed material is optimized, reducing friction and other forms of resistance caused by unnecessary displacement.

[0019] 2、By the first transmission chain and the first adjusting gear cooperation makes the two first gear rotation direction opposite, thereby driving two transmission shaft and two transmission above the wire hook rotation direction is also opposite, because two wire hook rotation direction opposite, in the wire process only will pull the outside iron wire, and will not pull and pull the iron wire between two wire hook back and forth thereby causing wear and tear.

[0020] 3、The first adjusting gear and the rotating drive element can be close to or away from the two first gears through the adjusting plate, when the first transmission chain needs to be repaired or replaced, only need to adjust the adjusting plate, so that the first adjusting gear and the rotating drive element close to the two first gears, so that the first transmission chain can be easily removed, after replacement, only need to adjust the first adjusting gear and the rotating drive element away from the two first gears, so that the first transmission chain is tight, thereby completing the replacement.

DETAILED DESCRIPTION

[0028] The following is the specific embodiment of the utility model and combining the drawings, the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixation" should be interpreted broadly. For example, "fixation" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection 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.

[0032] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0033] The specific embodiments described herein are merely illustrative examples of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the patent of this utility model or exceeding the scope defined by the appended claims.

[0034] like Figures 1-5 As shown, an eccentric stranded wire mechanism includes: a base 1, a stranded wire hook 2, and a drive assembly 3.

[0035] The stranded hook 2 is rotatably connected to the base 1. The stranded hook 2 includes a rotating shaft portion 21 and a rotating hook portion 22, and the rotating hook portion 22 is connected to the rotating shaft portion 21.

[0036] The drive assembly 3 includes a rotation drive element 31 and a transmission shaft 32. The rotation drive element 31 is connected to the transmission shaft 32 and can drive the transmission shaft 32 to rotate. The transmission shaft 32 is eccentrically connected to the rotating shaft portion 21. The rotation drive element 31 drives the stranded hook 2 to rotate through the transmission shaft 32.

[0037] Specifically, the rotating hook 22 is vertically connected to the rotating shaft 21, and the rotating drive element 31 drives the transmission shaft 32 to rotate. Because the connection between the rotating shaft 21 and the transmission shaft 32 is not coaxial but eccentric, that is, the center lines of the two do not coincide, but there is a certain offset in space, thus performing eccentric rotation.

[0038] In this embodiment, since the conventional stranding hook 2 usually rotates around a fixed central axis, the position of the center knot of the material needs to be constantly adjusted as the stranding hook 2 rotates to ensure uniform winding. However, this adjustment often leads to additional friction and resistance, thereby reducing stranding efficiency and potentially causing unnecessary stress on the material. In contrast, the stranding hook 2 with an eccentric rotation mechanism does not have a fixed rotation center, but moves along a predetermined eccentric path, so that the position of the center knot of the material can remain relatively stable without frequent large-scale offsets. Therefore, the contact between the stranding hook 2 and the material being processed is more optimized, reducing friction and other forms of resistance caused by unnecessary displacement between the two.

[0039] like Figures 1-5 As shown, based on the above embodiment, it also includes a first transmission chain 33 and a first gear 34. The first gear 34 is connected to one end of the transmission shaft 32, one end of the first transmission chain 33 meshes with the output part of the rotation drive element 31, and the other end of the first transmission chain 33 meshes with the first gear 34.

[0040] Specifically, when the rotation drive element 31 starts working, it rotates through its output shaft and transmits the rotational motion to the first gear 34 through the first transmission chain 33. Since the first transmission chain 33 and the first gear 34 are closely matched, the first gear 34 rotates accordingly, thereby driving the transmission shaft 32 connected to it to rotate together.

[0041] In this embodiment, a transmission method in which the first gear 34 and the first transmission chain 33 mesh is adopted to prevent slippage during transmission, thereby ensuring the stability and efficiency of the entire system.

[0042] like Figures 1-5As shown, based on the above embodiment, the number of transmission shafts 32 and the first gears 34 is two, and a first adjusting gear 35 is also included. The first adjusting gear 35 is rotatably connected to the base 1. The first transmission chain 33 meshes sequentially with the output shaft of the rotation drive element 31, one of the first gears 34, the first adjusting gear 35 and the other first gear 34, and finally returns to the output shaft of the rotation drive element 31 to form a closed loop.

[0043] Specifically, there are two drive shafts 32 and two first gears 34. The first drive chain 33 meshes with the rotation drive element 31, one of the first gears 34, the first adjusting gear 35 and the other first gear 34 in one operation. The first drive chain 33 meshes with the same side of the two first gears 34, but the moving directions of the meshing parts of the first drive chain 33 and the two first gears 34 are opposite, so that the rotation directions of the two first gears 34 are opposite.

[0044] In this embodiment, the first transmission chain 33 and the first adjusting gear 35 work together to make the two first gears 34 rotate in opposite directions, thereby driving the two transmission shafts 32 and the two wire hooks 2 on the transmission shafts to rotate in opposite directions. Since the two wire hooks 2 rotate in opposite directions, only the outer wire is pulled during the wire twisting process, and the wire between the two wire hooks 2 is not pulled back and forth, thus avoiding wear.

[0045] like Figures 1-5 As shown, based on the above embodiment, it also includes an adjustment plate 4. The first adjustment gear 35 and the rotation drive element 31 are both connected to the adjustment plate 4, and the adjustment plate 4 is slidably connected to the base 1.

[0046] Specifically, the first adjusting gear 35 is rotatably connected to the adjusting plate 4, so that the first adjusting gear 35 and the rotation driving element 31 can move relative to the two first gears 34 on the base 1.

[0047] In this embodiment, the first adjusting gear 35 and the rotation drive element 31 can be moved closer to or further away from the two first gears 34 by adjusting the plate 4. When the first transmission chain 33 needs to be repaired or replaced, simply adjust the plate 4 to bring the first adjusting gear 35 and the rotation drive element 31 closer to the two first gears 34, so that the first transmission chain 33 can be easily removed. After the replacement is completed, simply adjust the first adjusting gear 35 and the rotation drive element 31 away from the two first gears 34 to tighten the first transmission chain 33, thereby completing the replacement.

[0048] like Figures 1-5As shown, based on the above embodiment, it also includes a fastener (not shown in the figure). The adjusting plate 4 is provided with a first guide hole 41 and a receiving groove 42. The transmission shaft 32 is accommodated in the receiving groove 42 and can slide in the receiving groove 42. The fastener passes through the first guide hole 41 and is connected to the base 1. The fastener can slide in the first guide hole 41.

[0049] Specifically, the fastener can be a screw, and the base 1 is provided with a threaded hole. When the adjusting plate 4 needs to be moved, simply loosen the screw to push the adjusting plate 4 to move. After the movement is completed, tighten the screw to press the adjusting plate 4 against the base 1, thereby preventing it from moving.

[0050] In this embodiment, the drive shaft 32 is housed in the receiving groove 42, allowing it to pass through the adjusting plate 4 and be driven by the rotation drive element 31. Fasteners are used to securely fix the connection between the drive shaft 32 and the adjusting plate 4, while ensuring that it can be easily disassembled or adjusted when needed. The first guide hole 41 provides a clear path for the movement of the adjusting plate 4, allowing the adjusting plate 4 to slide smoothly on the predetermined track, avoiding unnecessary offset or shaking, thereby improving the overall stability and response speed of the system.

[0051] like Figures 1-5 As shown, based on the above embodiment, it also includes a second transmission chain 36, and the transmission shaft 32 is also provided with a second gear 37. The number of transmission shafts 32 is at least four, and in the vertical direction, two transmission shafts 32 are connected to each other by the second transmission chain 36 and two second gears 37 meshing together.

[0052] Specifically, the rotation drive element 31 and the first transmission chain 33 drive two transmission shafts 32 located on the same water surface to rotate relative to each other. The other two transmission shafts 32 are located in their vertical directions and are driven by the meshing of the second gear 37 and the second transmission chain 36.

[0053] In this embodiment, since the two transmission shafts 32 in the vertical direction are driven by the second gear 37 and the second transmission chain 36, the rotation direction and rotation speed of the two transmission shafts 32 are the same, thereby further enhancing the consistency of the stranding operation.

[0054] like Figures 1-5 As shown, based on the above embodiment, a second adjusting gear 38 is also included. The second adjusting gear 38 is slidably connected to the base 1 and meshes with the second transmission chain 36.

[0055] In this embodiment, the second adjusting gear 38 can be used to adjust the tension of the second transmission chain 36. When the second transmission chain 36 needs to be repaired or replaced, simply move the second adjusting gear 38 to disengage it from the second transmission chain 36, and the second transmission chain 36 can be removed for repair or replacement. When installing the second transmission chain 36, simply move the second adjusting gear 38 to engage it with the second transmission chain 36 to complete the installation.

[0056] like Figures 1-5 As shown, based on the above embodiment, the base 1 is provided with a second guide hole 11, and the second adjusting gear 38 is connected to the base 1 through the second guide hole 11.

[0057] In this embodiment, the second guide hole 11 provides a clear path for the movement of the second adjusting gear 38, allowing the second adjusting gear 38 to slide smoothly on the predetermined track, avoiding unnecessary offset or shaking, thereby improving the overall stability and response speed of the system.

[0058] like Figures 1-5 As shown, based on the above embodiment, the rotating hook 22 is further provided with a wire feeding part 221, the center of which is close to the center of the drive shaft 32.

[0059] Specifically, during the stranding process, the center knot is always located in the wire receiving section 221, and the wire receiving section 221 is relatively offset from the center of the drive shaft 32 during the eccentric rotation of the stranding hook 2.

[0060] In this embodiment, since the wire feeding section 221 is close to the rotating shaft section 21 and the center of the wire feeding section 221 is close to the center of the transmission shaft 32, the center knot is always located in the wire feeding section 221 during the stranding process, and the deviation is small, which improves the working efficiency of stranding.

[0061] like Figures 1-5 As shown, based on the above embodiment, the rotating shaft 21 is provided with a first inclined surface 211, and the transmission shaft 32 is provided with a second inclined surface 321, with the first inclined surface 211 in contact with the second inclined surface 321.

[0062] In this embodiment, the connection between the first inclined surface 211 and the second inclined surface 321 makes the center line of the rotating shaft and the center line of the transmission shaft 32 not lie on the same straight line, thereby achieving the purpose of eccentric connection, and thus making the stranded hook 2 rotate eccentrically during rotation.
