AI Technical Summary
In existing technologies, it is difficult to effectively control the tension of the core wires during the cable production process, resulting in poor cable quality.
The device employs a rocker arm and sleeve structure, combined with first and second elastic components. The rocker arm's movement causes the elastic components to deform, thereby adjusting the tension of the core wire. By utilizing the sliding fit between the sleeve and the rocker arm and the deformation of the elastic components, precise control of the core wire tension can be achieved.
Effectively controlling the tension of the core wires allows them to quickly return to a straight state, improving the quality and consistency of cable assembly.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production technology, and in particular to a tension adjustment mechanism for cable assembly. Background Technology
[0002] In the cable manufacturing process, multiple core wires are twisted together to form a cable core, and then a layer of wrapping tape is wrapped around the outside of the cable core to produce the finished cable. When supplying the core wires, a reel containing the core wires is typically placed on a pay-off frame, and the core wires are then guided out through guide rollers on the pay-off frame. To ensure that the core wires remain straight during the draw-out process, a suitable tension adjustment mechanism is required on the pay-off frame to control the tension of the core wires. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a tension adjustment mechanism for cable cabling, which can control the tension of the core wire during the core wire lead-out process.
[0004] Technical Solution: To achieve the above objectives, this utility model provides a tension adjustment mechanism for cable assembly, comprising a rocker arm and a sleeve; the rocker arm is movably mounted on a support, and a first elastic component is provided on the support, which deforms when the rocker arm is rocked; the lower end of the sleeve is fitted onto the rocker arm, and a tension wheel is installed on the upper end of the sleeve, with the core wire correspondingly passing over the tension wheel; the sleeve and the rocker arm are slidably engaged, and the sleeve and the rocker arm are connected by a second elastic component, which deforms when the sleeve and the rocker arm slide relative to each other.
[0005] Furthermore, the first elastic component includes a crossbar and a support spring; the crossbar is rotatably mounted on a support, and an eccentric wheel is provided at the lower end of the rocker arm. When the rocker arm is rocked, it can drive the eccentric wheel to rotate, and the eccentric wheel presses against the crossbar; the lower end of the support spring is mounted on the support, and the upper end of the support spring supports the crossbar, so that the crossbar and the eccentric wheel remain in contact; when the rocker arm is rocked, it can drive the support spring to deform through the eccentric wheel and the crossbar.
[0006] Furthermore, several winding wheels are installed on the crossbar, and the core wire is wound around several winding wheels before being wound onto the tensioning wheel.
[0007] Furthermore, the second elastic component includes an inner spring and an outer spring; the inner spring is disposed inside the sleeve, and the upper end of the rocker arm abuts against the inner spring; a groove is provided on the sleeve along its length, and an extension is connected to the rocker arm, the extension extending out of the sleeve from the groove; the outer spring is sleeved outside the sleeve, the lower end of the outer spring abuts against the annular part on the sleeve, and the upper end of the outer spring abuts against the extension.
[0008] Furthermore, the annular component is an adjusting nut, and the outer wall of the sleeve has an external thread structure that mates with the thread of the adjusting nut; the adjusting nut can rotate on the outer wall of the sleeve to change the degree of deformation of the outer spring and change the relative position of the sleeve and the rocker arm.
[0009] Furthermore, the sleeve has two opposite sliding grooves, each containing a protruding part; the protruding part is a threaded pin, and the rocker arm has a threaded hole that mates with the threaded pin, so that the threaded pin can be detachably installed on the rocker arm.
[0010] Beneficial effects: The tension adjustment mechanism for cable assembly of this utility model has the following beneficial effects:
[0011] 1) The sleeve is fitted onto the core wire, and the core wire passes over the tensioning wheel on the sleeve. When the tension of the core wire changes, it will drive the rocker arm to shake. When the rocker arm shakes, it will drive the first elastic component to deform, thereby controlling the tension of the core wire and restoring the core wire to a straight state.
[0012] 2) There is a second elastic component between the sleeve and the core wire. When the tension of the core wire changes, the second elastic component can also deform. With the cooperation of the first elastic component and the second elastic component, the tension of the core wire can be better controlled, and the core wire can be restored to a straight state more quickly, which is beneficial to controlling the quality of cable assembly.
[0013] 3) The second elastic component consists of an inner spring, an outer spring, and an adjusting nut. The deformation of the outer spring can be adjusted by adjusting the adjusting nut, thereby changing the relative position of the sleeve and the rocker arm to actively adjust the tension of the core wire.

[0016] Appendix Figure 3 This is a schematic diagram of the rocker arm and sleeve. Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] As attached Figures 1 to 3The cable tension adjustment mechanism includes a rocker arm 1 and a sleeve 2. The rocker arm 1 is rotatably mounted on a support 3, which is mounted on a pay-off frame. A pay-off reel containing core wires 6 is also placed on the pay-off frame. A first elastic component 4 is provided on the support 3, and the rocker arm 1 can deform the first elastic component 4 when rocked. The inner contour shape of the sleeve 2 is consistent with the outer contour shape of the rocker arm 1, so that the lower end of the sleeve 2 can fit on the rocker arm 1. A tensioning wheel 5 is installed on the upper end of the sleeve 2, and the core wires 6 led from the pay-off reel pass around the tensioning wheel 5. Due to the presence of the first elastic component 4, when the tension of the core wires 6 changes, it will cause the rocker arm 1 to rock, thereby causing a change in the elastic force of the first elastic component 4. In turn, it can control the tension of the core wires 6, so that the core wires 6 return to a straight state, ensuring the quality of the cable.
[0019] The sleeve 2 is slidably engaged with the rocker arm 1, meaning the sleeve 2 can slide along the rocker arm 1. The sleeve 2 and the rocker arm 1 are connected by a second elastic component 7. When the sleeve 2 slides relative to the rocker arm 1, it causes the second elastic component 7 to deform. Due to the presence of the second elastic component 7, when the tension of the core wire 6 changes, the second elastic component 7 can also adjust the tension of the core wire 6, allowing the core wire 6 to return to a straight state more quickly, which is beneficial for controlling the quality of cable assembly.
[0020] As attached Figure 1 As shown, the first elastic component 4 includes a crossbar 8 and a support spring 9. The crossbar 8 is rotatably mounted on the support 3, that is, one end of the crossbar 8 is hinged to the support 3. An eccentric wheel 10 is provided at the lower end of the rocker arm 1. When the rocker arm 1 is rocked, it drives the eccentric wheel 10 to rotate, and the eccentric wheel 10 presses against the crossbar 8, with the wheel surface of the eccentric wheel 10 in contact with the upper surface of the crossbar 8. The lower end of the support spring 9 is mounted on the support 3, and the upper end of the support spring 9 supports the crossbar 8, thereby keeping the crossbar 8 in contact with the eccentric wheel 10. When the rocker arm 1 is rocked, it drives the eccentric wheel 10 to rotate. When the eccentric wheel 10 rotates, the contact position between the eccentric wheel 10 and the crossbar 8 changes, causing the crossbar 8 to rotate to a certain extent. When the crossbar 8 rotates, the support spring 9 deforms accordingly. The deformation of the support spring 9 can adjust the tension of the core wire 6, thereby restoring the core wire 6 to a straight state.
[0021] As attached Figure 2 As shown, several winding wheels 11 are also installed on the crossbar 8. The core wire 6 is wound around the winding wheels 11 and then wound around the tension wheel 5. When the tension of the core wire 6 changes, the core wire 6 can directly drive the crossbar 8 to rotate, thereby deforming the support spring 9. In this way, the core wire 6 can also be restored to a straight state more quickly.
[0022] As attached Figure 3As shown, the second elastic component 7 includes an inner spring 12 and an outer spring 13. The inner spring 12 is disposed inside the upper part of the sleeve 2, and the upper end of the rocker arm 1 abuts against the inner spring 12. A groove 14 is formed on the sleeve 2 along its length direction, and an extension is connected to the rocker arm 1, extending out of the sleeve 2 from the groove 14. The outer spring 13 is sleeved on the outside of the sleeve 2, and is located below the inner spring 12. An annular part is provided on the outer wall of the sleeve 2, and the lower end of the outer spring 13 abuts against the annular part on the sleeve 2, while the upper end of the outer spring 13 abuts against the extension.
[0023] When the core wire 6 becomes loose, the inner spring 12 and the outer spring 13 will extend accordingly, causing the sleeve 2 to slide upward relative to the rocker arm 1, thereby tightening the core wire 6 and restoring it to a straight state. When the core wire 6 becomes tight, the inner spring 12 and the outer spring 13 will be compressed, causing the sleeve 2 to slide downward relative to the rocker arm 1.
[0024] The annular component is an adjusting nut 15, and the outer wall of the sleeve 2 has an external thread structure that engages with the adjusting nut 15. The adjusting nut 15 can rotate on the outer wall of the sleeve 2 to change the degree of deformation of the outer spring 13 and change the relative position of the sleeve 2 and the rocker arm 1, thereby actively adjusting the tension of the core wire 6.
[0025] The sleeve 2 has two opposing grooves 14, each containing a protruding part, which makes the force on both sides of the rocker arm 1 more balanced. The protruding part is a threaded pin 16, and the rocker arm 1 has a threaded hole that mates with the threaded pin 16, so that the threaded pin 16 can be detachably installed on the rocker arm 1. Because the threaded pin 16 is detachable, it is convenient to fit the sleeve 2 onto the rocker arm 1 when assembling the sleeve 2 and the rocker arm 1.
[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
