Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to an aluminum profile stranding device. Background Technology

[0002] Cables play an important role in life. They are usually made up of several or several groups of conductors twisted together into a rope-like shape. Each group of conductors is insulated from each other, and the whole cable is covered with a highly insulating outer layer. Only by twisting together can a cable be guaranteed to be practical. Twisting equipment is required to twist cables.

[0003] By comparing the cable stranding device with patent publication number CN220672294U, this solution achieves position adjustment of the threading hole, thereby adapting to cables with different tensile strengths, expanding the applicability of the device, and reducing cable damage. However, in actual use, because the distance between multiple threading holes and the rotating rod is adjusted independently, the synchronization is poor. Consequently, when the device is affected by external vibrations or different material properties of the cable itself, the distance between a certain threading hole and the rotating rod may become inconsistent. This results in poor cable winding tightness during cable winding, which may lead to uneven winding, reducing the quality of cable winding and lowering the pass rate of cable production.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An aluminum wire stranding device includes a base plate, a pressing mechanism provided on the rear side of the base plate, and a winding mechanism for winding a cable, the winding mechanism being located on the front side of the base plate.

[0007] The winding mechanism includes a support platform located on the front side of the base plate. A fixed sleeve is rotatably mounted on the upper end of the support platform. A wire-laying sleeve is rotatably mounted on the front side of the fixed sleeve. Multiple wire-laying wheels are rotatably mounted on the surface of the wire-laying sleeve, and the multiple wire-laying wheels are distributed around the center of the wire-laying sleeve. A rotating disk is located on the rear side of the wire-laying sleeve. The rotating disk is rotatably connected to the fixed sleeve. Multiple connecting rods are fixed between the rotating disk and the wire-laying sleeve. Multiple sliding grooves are circumferentially opened on the rotating disk. Sliding seats are slidably mounted in the sliding grooves. Tensioning rollers are rotatably mounted on the sliding seats. A cable core passes through the inside of the fixed sleeve.

[0012] Preferably, a torsion spring is connected between the rotating end of the tension roller and the sliding seat, and the tension roller is inclined downward.

[0013] Compared with existing technologies, the beneficial effects are as follows:

[0014] The winding mechanism rotates and winds multiple strands of cable onto the surface of the cable core. During winding, the spacing between multiple tension rollers and the fixed sleeve can be adjusted synchronously using an adjustment component to adapt to winding operations of cables with different material properties. This reduces the damage to the cable caused by the tension generated during winding. By utilizing the synchronicity of the movement of multiple tension rollers, it prevents inconsistencies in the spacing between a tension roller and the fixed sleeve, thereby improving the tightness of the cable winding, making the winding more uniform, improving the quality of cable winding, and increasing the pass rate of cable production.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6 As shown, an aluminum wire stranding device includes a base plate 100, a clamping mechanism for clamping and fixing the wound cable, the clamping mechanism being located on the rear side of the base plate 100, and a winding mechanism for winding the cable, the winding mechanism being located on the front side of the base plate 100.

[0027] In this embodiment: the winding mechanism includes a support platform 201 disposed on the front side of the base plate 100. A fixed sleeve 202 is rotatably mounted on the upper end of the support platform 201. A wire-holding sleeve 204 is rotatably mounted on the front side of the fixed sleeve 202. A rotary motor 203 is disposed above the support platform 201. The output end of the rotary motor 203 is connected to the wire-holding sleeve 204 by a belt drive. Multiple wire-holding wheels 205 are rotatably mounted on the surface of the wire-holding sleeve 204. The multiple wire-holding wheels 205 are distributed around the center of the wire-holding sleeve 204. A guide roller 206 is rotatably mounted on the rear side of the wire-holding sleeve 204 near the end of the wire-holding wheels 205. A rotating disk 208 is provided, which is rotatably connected to a fixed sleeve 202. Multiple connecting rods 207 are fixed between the rotating disk 208 and the overhead cable sleeve 204. Multiple sliding grooves 209 are circumferentially formed on the rotating disk 208. A sliding seat 210 is slidably installed in the sliding groove 209. A tension roller 211 is rotatably installed on the sliding seat 210. A torsion spring is connected between the rotating end of the tension roller 211 and the sliding seat 210. The tension roller 211 is inclined downward. A cable core 400 passes through the fixed sleeve 202. An adjustment component for adjusting the position of the multiple tension rollers 211 is provided on the front side of the rotating disk 208.

[0028] The adjustment assembly includes an adjustment disc 212 located in front of the rotating disc 208. The adjustment disc 212 is rotatably connected to the fixed sleeve 202. A rotating handle is fixed to the front end of the adjustment disc 212. Multiple clamping cylinders 214 are provided between the front end of the adjustment disc 212 and the rear end of the cable-holding sleeve 204 to lock the position of the adjustment disc 212 and prevent it from rotating. A rotating plate 213 is rotatably installed between the adjustment disc 212 and the sliding seat 210. The winding mechanism rotates and winds multiple strands of cable onto the surface of the cable core 400. During winding, the adjustment assembly can also be used to synchronously adjust the spacing between multiple tension rollers 211 and the fixed sleeve 202 to adapt to the winding operation of cables with different material properties, reduce the tension generated during the winding process and prevent damage to the cable. By utilizing the synchronicity of the movement of multiple tension rollers 211, it prevents the spacing between a certain tension roller 211 and the fixed sleeve 202 from being inconsistent, thereby improving the tightness of the cable winding, making the winding more uniform, improving the quality of cable winding, and increasing the pass rate of cable production.

[0029] In this embodiment: the pressing mechanism includes a support plate 301 disposed at the rear end of the base plate 100. An upper pressure roller 302 is rotatably mounted on the upper end of the support plate 301, and a lower pressure roller 303 is disposed below the upper pressure roller 302. The lower pressure roller 303 is rotatably connected to the support plate 301. A pressing motor 304 is mounted on the rotating end of the upper pressure roller 302. The cable core 400 passes between the upper pressure roller 302 and the lower pressure roller 303. A take-up roller 305 is rotatably mounted at the rear end of the support plate 301. A winding motor 306 is installed at the rotating end of 05. It drives the pressing motor 304 to rotate the upper pressure roller 302. The upper pressure roller 302 and the lower pressure roller 303 work together to press the surface of the wound cable core 400 to eliminate the stress of the cable wrapped on the surface of the cable core 400 and reduce the cable from unraveling on the surface of the cable core 400. Finally, the winding motor 306 drives the winding roller 305 to rotate, thereby winding the wound and pressed cable core 400 onto the winding roller 305.

[0030] Working principle: First, the cable core 400 is passed through the fixed sleeve 202, the upper pressure roller 302, and the lower pressure roller 303. Then, the multiple strands of cable to be wound are placed on the wire-laying roller 205, so that the multiple strands of cable pass through the upper end of the guide roller 206, around the upper end of the tension roller 211, and are wound on the surface of the cable core 400. Then, the drive motor 203 drives the wire-laying sleeve 204 and the rotating disk 208 to rotate, driving the multiple strands of cable to rotate and wrap the multiple strands of cable on the surface of the cable core 400. The cable will be subjected to a certain tension when it is wound. Then, the torsion spring set between the tension roller 211 and the sliding seat 210 can adaptively adjust the rotation position of the tension roller 211. In this way, the cable drives the tension roller 211 to rotate downward, reducing the large friction between the cable and the tension roller 211 and causing damage to the cable.

[0031] Then, the pressure motor 304 is driven to rotate the upper pressure roller 302, which, together with the lower pressure roller 303, presses the surface of the wound cable core 400 to eliminate the stress of the cable wrapped on the surface of the cable core 400 and reduce the cable from unraveling on the surface of the cable core 400. Finally, the winding motor 306 is driven to rotate the winding roller 305, which then winds the wound and pressed cable core 400 onto the winding roller 305.

[0032] When producing cables of different materials, the adjustment disc 212 is rotated by manually turning the rotary handle. The thrust of multiple rotating plates 213 drives multiple sliding seats 210 to slide synchronously within the grooves 209 of the rotating disc 208. This adjusts the distance between multiple tension rollers 211 and the fixed sleeve 202, ensuring that the tension on each cable is consistent during winding. This prevents inconsistencies in the distance between a tension roller 211 and the fixed sleeve 202, thereby improving the tightness and uniformity of the cable winding, enhancing the quality of the cable winding, increasing the pass rate of cable production, and expanding the applicability of the device. Finally, multiple clamping cylinders 214 are driven to move backward to clamp the adjustment disc 212, preventing rotation during cable winding.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
