[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model provides a clutch tension adjustment device for twisting cores of a digital communication network, comprising a base 1, on the surface of which a driven bevel gear stage 22, a bearing bracket, two groups of open frames 10 and a twisting machine box 11 are fixedly provided; on the surface of the driven bevel gear stage 22, an upper wire roller 23 and a lower wire roller 24 are fixedly provided; on the top of the two groups of open frames 10, a bearing ring frame 16 is fixedly provided, a driven ring 2 is rotated on the left bearing ring frame 16, and an adjusting ring 17 is rotated on the right bearing ring frame 16, and a rack 18 is provided around the outer ends of the driven ring 2 and the adjusting ring 17;

[0027] A rectangular frame 26 is fixed radially inside the driven ring 2, and a group of curved discs 5 are arranged opposite to each other in the upper and lower parts of the rectangular frame 26. Fixed pins 3 are arranged on both sides of the curved discs 5. The outer sides of the fixed pins 3 are threadedly connected with locking screw sleeves 4. A handle 6 is fixed on the end surface of the curved disc 5. A wire roller 7 is rotatably connected to the inside of the curved disc 5 through a rotating pin. The curved disc 5 with an adjusted angle can be fixed in the rectangular frame 26 by the coordinated use of the fixed pins 3 and the locking screw sleeves 4.

[0028] The end surface of the adjusting ring 17 is provided with a racetrack-shaped slide groove 19 on both sides of the center of the circle. A cable harness 20 is slidably arranged inside the racetrack-shaped slide groove 19. An electric push rod 21 is installed inside the racetrack-shaped slide groove 19.

[0029] The right open frame 10 is provided with a side bracket 13, and the side bracket 13 is installed with a motor 14. The output shaft of the motor 14 is provided with two sets of driving gear discs 15, and the end of the output shaft is provided with driving bevel gears 25;

[0030] By placing the upper wire core 8 below the upper wire roller 7 and the lower wire core 9 above the lower wire roller 7, the upper wire core 8 and the lower wire core 9 are passed through the cable sheath 20 and the stranding machine box 11 and moved to the right, the stability of the wire core tension is improved.

[0031] Furthermore, the electric push rod 21 is located at the inner end of the runway-shaped slide 19, and the cable sleeve 20 is located at the outer end of the runway-shaped slide 19. The cable sleeve 20 is fixed on one end of the electric push rod 21. The electric push rod 21 drives the cable sleeve 20 to move radially along the adjustment ring 17, so as to adjust the distance between the two groups of cable sleeves 20, thereby further effectively adjusting the tension of the wire core during the transportation process.

[0032] Furthermore, the driving gear disc 15 is meshed with the rack 18, and the rack 18 is located on the outside of the bearing ring frame 16. When the motor 14 is started, the driving gear disc 15 can be driven to rotate, and through the meshing of the driving gear disc 15 and the rack 18, the driven ring 2 and the adjusting ring 17 can be driven to rotate synchronously in the same direction.

[0033] Furthermore, the two groups of wire rollers 7 are in contact with the upper wire core 8 and the lower wire core 9 respectively, and the upper wire core 8 and the lower wire core 9 pass through the cable sleeve 20 and the twisting machine box 11, so that the upper wire core 8 and the lower wire core 9 that have not been twisted can be tensioned and adjusted by the oblique movement of the wire rollers 7 to prevent the wire core from being too loose and affecting the subsequent twisting process. The tensioned upper wire core 8 and the lower wire core 9 pass through the cable sleeve 20 that can rotate along the circumferential direction of the adjustment ring 17. According to the thickness of the wire core and the required twisting strength, the distance between the cable sleeves 20 is adjusted, thereby adjusting the tension between the wire core and the wire gathering mouth 12. After the wire core passes through the cable sleeve 20, it is wound into a strand and gathered towards the wire gathering mouth 12 as the adjustment ring 17 rotates.

[0034] Furthermore, a wire gathering port 12 and a wire outlet 27 are respectively provided on both sides of the stranding machine box 11. The centers of the wire gathering port 12 and the wire outlet 27 are in the same straight line as the center of the adjustment ring 17. The wire gathering port 12 can gather the upper and lower wire cores.

[0035] Furthermore, the driving bevel gear 25 meshes with the bottom of the driven bevel gear stage 22 . When the motor 14 drives the driven ring 2 and the adjustment ring 17 to rotate synchronously, the driving bevel gear 25 also rotates, thereby causing the driven bevel gear stage 22 to rotate.

[0036] Furthermore, the upper line roller 23 and the lower line roller 24 are designed as a high and low structure, and the upper line core 8 is wound on the upper line roller 23, and the lower line core 9 is wound on the lower line roller 24. When the driven bevel gear table 22 rotates, the upper line roller 23 and the lower line roller 24 are driven to rotate. When the upper line roller 23 on the high side rotates to the rightmost side of the driven bevel gear table 22, the lower line roller 24 is located at the leftmost side of the driven bevel gear table 22. During the rotation process, the upper line core 8 is always located above the lower line core 9, which effectively avoids the upper and lower line cores from being entangled with each other.

[0037] When in use, first lead the wire core from the wire roller, pass the upper wire core 8 and the lower wire core 9 through the upper and lower wire rollers 7 respectively, and place the upper wire core 8 below the upper wire roller 7, and place the lower wire core 9 above the lower wire roller 7, then pass the upper wire core 8 and the lower wire core 9 through the cable sheath 20 and the stranding machine box 11 and move them to the right, as shown in FIG. Figure 1 By adjusting the handle 6, the upper curved disc 5 is rotated clockwise to make the upper wire roller 7 move obliquely downward, and the upper wire core 8 is pressed downward, and the lower curved disc 5 is rotated counterclockwise to make the lower wire roller 7 move obliquely upward, and the lower wire core 9 is pressed upward, so as to adjust the tension state of the wire core to prevent the wire core from being too loose and affecting the subsequent twisting process. At the same time, the locking screw sleeve 4 is rotated to fix the curved disc 5 in the rectangular frame 26, so that the upper and lower wire rollers 7 can stably guide their respective wire cores. After the upper wire core 8 and the lower wire core 9 are tensioned and adjusted, the motor 14 is started to drive the driven ring 2 and the adjusting ring 17 to rotate synchronously in the same direction. At the same time, the driving bevel gear 25 also rotates, thereby causing the driven bevel gear stage 22 to rotate. The adjusting ring 17 drives the two sets of cable shrouds 20 to rotate along its circumferential direction, and the electric push rod 21 drives the cable shrouds 20 to move radially along the adjusting ring 17. According to the thickness of the wire core and the required twisting strength, the distance between the two sets of cable shrouds 20 is adjusted, thereby adjusting the tension between the wire core and the wire gathering port 12, further improving the stability of the wire core during transportation. The wire core of the two sets of cable shrouds is wound into a strand with the rotation of the adjusting ring 17 and gathered towards the wire gathering port 12, and enters the wire twisting machine box 11 to complete the twisting process.
