Description

Technical Field

[0001] This utility model relates to the technical field of cable production equipment, specifically an adjustable-spacing cable conductor stranding device. Background Technology

[0002] In the cable manufacturing process, stranding is a crucial step in combining multiple conductors according to a specific pattern to form the cable core. Currently, cable conductor stranding devices on the market have limitations in adjusting the stranding spacing. Traditional stranding devices typically only perform stranding operations at a fixed spacing, making it difficult to meet the diverse spacing requirements of cables of different specifications and applications. Changing the stranding spacing often requires replacing specific molds or making complex mechanical adjustments, which not only increases production costs but also reduces production efficiency. Therefore, those skilled in the art have proposed an adjustable-spacing cable conductor stranding device to address the problems mentioned above. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable-spacing cable conductor stranding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adjustable-gap cable conductor stranding device includes a support base, a drive assembly, and a stranding assembly. Both the drive assembly and the stranding assembly are connected to the support base. The stranding assembly includes a cable laying section and a cable take-up section. The drive assembly includes a drive frustum and a drive pulley. The drive frustum has a conical structure. The drive pulley contacts the conical edge of the drive frustum through a position adjustment mechanism. By adjusting the contact position, the transmission ratio is changed, thereby driving the cable laying section and the cable take-up section to synchronously adjust the cable laying speed and the cable take-up speed, thereby adjusting the spacing of the cable strands.

[0006] As a further embodiment of this utility model: the driving assembly includes a supporting vertical plate, a driving horizontal bar, a supporting inclined platform, a driving plate, a driving frustum, a driving screw, and a driving rod. Two sets of supporting vertical plates and supporting inclined platforms are fixedly connected to the supporting base.

Two sets of driving plates are fixedly connected to the supporting inclined platform and are perpendicular to the platform surface. A driving screw and a driving rod are rotatably connected between the driving plates.

[0007] As a further embodiment of this utility model: the drive assembly also includes a drive crank, a drive motor, a drive screw block, a connecting frame, and a drive pulley. One end of the drive screw passes through the drive plate and is fixedly connected to the drive crank. One end of the drive rod passes through the drive plate and is fixedly connected to the output shaft of the drive motor. The drive screw block is threaded with a drive screw block. The drive pulley is slidably connected to the drive rod. The drive screw block is fixedly connected to the connecting frame. The connecting frame is rotatably connected to the drive pulley. The drive pulley abuts against the drive frustum.

[0008] As a further embodiment of this utility model: the cable-laying section includes an L-shaped support plate, a first transmission rod, a second transmission rod, a cable-laying frame, a conductor disc, a disc frame, a drive wheel, a transmission wheel, a transmission belt, a first bevel gear, and a second bevel gear. The L-shaped support frame and the disc frame are fixedly connected to the support base. The conductor disc is rotatably connected inside the disc frame. The first transmission rod is rotatably connected to one side wall of the L-shaped support frame, and the second transmission rod is rotatably connected to the other side wall of the L-shaped support frame. The end of the second transmission rod is fixedly connected to the conductor disc. The cable-laying frame is fixedly connected to the second transmission rod.

The drive wheel and the transmission wheel are connected by a transmission belt. The end of the first drive rod is fixedly connected to the first bevel gear, and the second transmission rod is fixedly connected to the second bevel gear. The first bevel gear and the second bevel gear mesh with each other.

[0009] As a further embodiment of this utility model: the cable take-up section includes a take-up mold, a take-up vertical plate, a take-up horizontal bar, and a take-up roller. The take-up mold and the take-up vertical plate are fixedly connected to the support base. One end of the drive horizontal bar passes through the support vertical plate and is fixedly connected to the take-up horizontal bar. The other end of the take-up horizontal bar is rotatably connected to the take-up vertical plate. The take-up roller is fixedly connected to the take-up horizontal bar.

[0010] Compared with existing technologies, the beneficial effects of this invention are as follows: This device changes the transmission ratio by adjusting the contact position between the drive pulley and the conical edge of the drive frustum, thereby synchronously adjusting the speed of the cable laying and take-up sections. This allows for flexible adjustment of the cable bundle stranding spacing, meeting the production needs of cables of different specifications and greatly improving the versatility and adaptability of the device. The drive assembly is manually adjusted by a drive crank or automatically adjusted by a drive motor, which moves the drive screw block and connecting frame, thereby changing the position of the drive pulley on the drive frustum. Operation is simple and adjustment is precise. The coordinated cooperation between the cable laying and take-up assemblies and the drive assembly ensures the stability and synchronization of cable laying and take-up during the cable stranding process, effectively improving the quality and production efficiency of the cable stranding.

[0024] Example 1

[0025] Please see Figure 1-8 An adjustable-gap cable conductor stranding device includes a support base 1, a drive assembly 2, and a stranding assembly 3. The drive assembly 2 and the stranding assembly 3 are both connected to the support base 1. The stranding assembly 3 includes a cable laying section and a cable take-up section. The drive assembly 2 includes a drive frustum 205 and a drive pulley 212. The drive frustum 205 has a conical structure. The drive pulley 212 contacts the conical edge of the drive frustum 205 through a position adjustment mechanism. By adjusting the contact position, the transmission ratio is changed, thereby driving the cable laying section and the cable take-up section to synchronously adjust the cable laying speed and the cable take-up speed, thereby adjusting the spacing of the cable stranding.

[0026] The drive assembly 2 includes a support vertical plate 201, a drive horizontal bar 202, a support inclined platform 203, a drive plate 204, a drive frustum 205, a drive screw 206, and a drive rod 207. Two sets of support vertical plates 201 and support inclined platforms 203 are fixedly connected to the support base 1. The support inclined platforms 203 are located between the support vertical plates 201. The drive horizontal bar 202 is rotatably connected between the support vertical plates 201. The drive frustum 205 is fixedly connected to the drive horizontal bar 202. The inclined surface of the supported inclined platform 203 is parallel to the conical surface of the drive frustum 205. Two sets of drive plates 204 are fixedly connected to the support inclined platform 203 and are perpendicular to the platform surface of the support inclined platform 203. The drive screw 206 and the drive rod 207 are rotatably connected between the drive plates 204.

[0027] The drive assembly 2 also includes a drive crank 208, a drive motor 209, a drive screw block 210, a connecting frame 211, and a drive pulley 212. One end of the drive screw 206 passes through the drive plate 204 and is fixedly connected to the drive crank 208. One end of the drive rod 207 passes through the drive plate 204 and is fixedly connected to the output shaft of the drive motor 209. The drive screw 206 is threaded with a drive screw block 210. The drive pulley 212 is slidably connected to the drive rod 207. The drive screw block 210 is fixedly connected to the connecting frame 211. The connecting frame 211 is rotatably connected to the drive pulley 212. The drive pulley 212 abuts against the drive frustum 205.

[0028] In drive assembly 2, after drive motor 209 starts, it drives drive rod 207 to rotate, which in turn drives drive frustum 205 to rotate under the support of drive crossbar 202. When it is necessary to adjust the transmission ratio, drive crank 208 can be rotated to make drive screw 206 rotate. Drive screw block 210 on drive screw 206 moves along drive screw 206 under the action of the thread. Drive screw block 210 drives drive pulley 212 to slide on drive rod 207 through connecting bracket 211. Since drive pulley 212 contacts the conical edge of drive frustum 205, the change in position of drive pulley 212 causes the rotation radius at the contact point with drive frustum 205 to change, thereby realizing the adjustment of transmission ratio. When drive pulley 212 moves towards the large end of drive frustum 205, the speed of cable laying and cable winding decreases accordingly; when drive pulley 212 moves towards the small end of drive frustum 205, the speed of cable laying and cable winding increases accordingly.

[0029] Example 2

[0030] This embodiment adds the following improvements to Embodiment 1: The cable-laying section includes an L-shaped support plate 301, a first transmission rod 302, a second transmission rod 303, a cable-laying frame 304, a conductor disc 305, a disc frame 306, a drive wheel 307, a transmission wheel 308, a transmission belt 309, a first bevel gear 310, and a second bevel gear 311. An L-shaped support frame and a disc frame 306 are fixedly connected to the support base 1. The conductor disc 305 is rotatably connected inside the disc frame 306. The first transmission rod 302 is rotatably connected to one side wall of the L-shaped support frame, and the other side wall of the L-shaped support frame is rotatably connected to the first transmission rod 302. A second transmission rod 303 is movably connected, and the end of the second transmission rod 303 is fixedly connected to the wire disc 305. A wire feeding frame 304 is fixedly connected to the second transmission rod 303. A drive wheel 307 is fixedly connected to the drive crossbar 202. A drive wheel 308 is fixedly connected to the first transmission rod 302. The drive wheel 307 and the drive wheel 308 are connected by a transmission belt 309. A first bevel gear 310 is fixedly connected to the end of the first drive rod 207. A second bevel gear 311 is fixedly connected to the second transmission rod 303. The first bevel gear 310 and the second bevel gear 311 mesh with each other.

[0031] When the driving frustum 205 rotates, it drives the driving wheel 307 on the driving crossbar 202 to rotate. The driving wheel 307 transmits power to the transmission wheel 308 on the first transmission rod 302 via the transmission belt 309, causing the first transmission rod 302 to rotate. The first bevel gear 310 at the end of the first transmission rod 302 meshes with the second bevel gear 311 on the second transmission rod 303, thereby transmitting power to the second transmission rod 303. When the second transmission rod 303 rotates, it drives the conductor disc 305 fixedly connected to its end and the wire feeding frame 304 fixed on the second transmission rod 303 to rotate. The conductor disc 305 is used to guide the cable conductor, and the wire feeding frame 304 is used to place the cable conductor to be bundled. During rotation, the wire feeding frame 304 releases the cable conductor, providing raw materials for the bundling operation.

[0032] The cable take-up section includes a take-up mold 312, a take-up vertical plate 313, a take-up horizontal bar 314, and a take-up roller 315. The take-up mold 312 and the take-up vertical plate 313 are fixedly connected to the support base 1. One end of the drive horizontal bar 202 passes through the support vertical plate 201 and is fixedly connected to the take-up horizontal bar 314. The other end of the take-up horizontal bar 314 is rotatably connected to the take-up vertical plate 313. The take-up roller 315 is fixedly connected to the take-up horizontal bar 314.

[0033] When the drive bar 202 rotates, it drives the take-up bar 314, which is fixedly connected at one end, to rotate. The take-up bar 314 then drives the take-up roller 315, which is fixed on it, to rotate. During the cable stranding operation, the cable conductor released from the cable release assembly is stranded and formed by the take-up die 312. The formed cable is then wound and collected by the take-up roller 315, completing the cable stranding and take-up work.

[0034] Working principle

[0035] In drive assembly 2, after drive motor 209 starts, it drives drive rod 207 to rotate, which in turn drives drive frustum 205 to rotate under the support of drive crossbar 202. When it is necessary to adjust the transmission ratio, drive crank 208 can be rotated to make drive screw 206 rotate. Drive screw block 210 on drive screw 206 moves along drive screw 206 under the action of the thread. Drive screw block 210 drives drive pulley 212 to slide on drive rod 207 through connecting bracket 211. Since drive pulley 212 contacts the conical edge of drive frustum 205, the change in position of drive pulley 212 causes the rotation radius at the contact point with drive frustum 205 to change, thereby realizing the adjustment of transmission ratio. When drive pulley 212 moves towards the large end of drive frustum 205, the speed of cable laying and cable winding decreases accordingly; when drive pulley 212 moves towards the small end of drive frustum 205, the speed of cable laying and cable winding increases accordingly.

[0036] When the driving frustum 205 rotates, it drives the driving wheel 307 on the driving crossbar 202 to rotate. The driving wheel 307 transmits power to the transmission wheel 308 on the first transmission rod 302 via the transmission belt 309, causing the first transmission rod 302 to rotate. The first bevel gear 310 at the end of the first transmission rod 302 meshes with the second bevel gear 311 on the second transmission rod 303, thereby transmitting power to the second transmission rod 303. When the second transmission rod 303 rotates, it drives the conductor disc 305 fixedly connected to its end and the wire feeding frame 304 fixed on the second transmission rod 303 to rotate. The conductor disc 305 is used to guide the cable conductor, and the wire feeding frame 304 is used to place the cable conductor to be bundled. During rotation, the wire feeding frame 304 releases the cable conductor, providing raw materials for the bundling operation.

[0037] When the drive bar 202 rotates, it drives the take-up bar 314, which is fixedly connected at one end, to rotate. The take-up bar 314 then drives the take-up roller 315, which is fixed on it, to rotate. During the cable stranding operation, the cable conductor released from the cable release assembly is stranded and formed by the take-up die 312. The formed cable is then wound and collected by the take-up roller 315, completing the cable stranding and take-up work.
