Description
Technical Field
[0001] The utility model relates to a cable guiding and conveying structure of a untwisting machine. Background Art
[0002] Data network cables are composed of multiple strands of twisted pairs. The twisted pair is composed of two copper wires with insulating protective layers twisted together at a certain density. Through the twisting setting, the electric waves radiated by one wire during transmission are offset by the electric waves emitted by the other wire, thereby reducing signal interference.
[0003] During the twisting process, generally, a untwisting machine is required to control the network cable to rotate to a certain extent, so as to generate necessary untwisting force on the cable to eliminate the original twisting phenomenon of the cable, and ensure the consistency and effect of the twisting of the network cable. However, when conventional vertical untwisting machines and the like convey network cables, due to the thinness of the network cables, they are extremely prone to breakage. If the cables are conveyed too loosely, since the network cables are in a loose state, it is not conducive to the initial rotation and bending of the network cables, and it is difficult to eliminate the original twisting problem of the cables. As a result, when the subsequent cables are twisted, untwisting occurs due to uneven local stress inside the cables, affecting the twisting and stranding effect of the network cable twisted pair.

[0022] The tension spring 32 is sleeved outside the wire barrel 3. One end of the tension spring 32 is connected to the top cover 31, and the other end of the tension spring 32 is connected to the lower surface of the cavity 22 inside the connecting column 2. The tension spring 32 can pull the wire barrel 3 through the top cover 31 and the connecting column 2, so that the top cover 31 is as close as possible to the upper surface of the connecting column 2, so as to make the wire barrel 3 in a downward pressure state.

[0026] The range of the included angle a is between 110 degrees and 135 degrees. A groove (not labeled) is provided in the center of the guide post 6. The range of the included angle a is within 120 degrees, facilitating the cable 8 to pass through the guide post 6, the guide wheel 5, and the track wheel 4 in sequence and enter the bobbin 3, reducing the possible breakage of the cable 8 caused by small-angle bends such as right angles or acute angles. At the same time, the groove in the center of the guide post 6 facilitates the guiding and limiting of the cable 8 during conveyance.
[0027] The cable guiding and conveying structure of this untwisting machine conveys the cable 8 to the center of the guiding wheel 5 through the limit of the central groove of the guiding column 6, and enters the track wheel 4 through the guiding of the guiding wheel 5. A sliding rod 41 is movably connected behind the track wheel 4, and the sliding rod 41 slides in the waist-shaped hole 12 in the center of the vertical plate 1. A locking rod 51 is movably connected behind the guiding wheel 5, and the distance between the guiding wheel 5 and the track wheel 4 is adjusted by the elastic force of the pushing spring 13 between the sliding rod 41 and the locking rod 51 to automatically adjust the tightness of the cable 8 after passing through the guiding wheel 5 and the track wheel 4. Then, it enters the wire groove 33 inside the bobbin 3 through the track wheel 4. A tension spring 32 connected to the outer top cover 31 of the bobbin 3 is connected in the cavity 22 inside the connecting column 2. The elastic deformation of the tension spring 32 enables the wire groove 33 to adjust the tightness of the cable 8 through the height difference between the lower end of the bobbin 3 and the track wheel 4 after entering the bobbin 3. The structure of the arc opening 34 at the lower end of the bobbin 3 ensures the smooth entry of the cable 8 into the wire groove 33. Then, the cable 8 enters the installed untwisting machine for rotational twisting after passing through the wire groove 33.
[0028] The beneficial effects of the present utility model are as follows: Since the vertical plate is movably connected to the connecting column through a sleeve, and the guiding column and the track wheel are movably connected to the surface of the vertical plate, the cable can be guided through the guiding wheel. And because the vertical plate can rotate relative to the connecting column, the guiding wheel can be accurately oriented towards the direction in which the cable is input into the guiding wheel, ensuring the accurate guiding of the cable input by the guiding wheel and reducing the situation where the cable input breaks away from the guiding and conveying structure. A waist-shaped hole is provided in the center of the vertical plate, and a sliding rod movably connected to the track wheel is slidably arranged inside the waist-shaped hole, enabling the track wheel to adjust the distance between the track wheel and the guiding wheel through the sliding of the sliding rod in the waist-shaped hole. Through the locking rod movably connected to the guiding wheel and the pushing spring connected between the locking rod and the sliding rod, the track wheel and the guiding wheel can have a certain tightness adjustment effect through the spring deformation of the pushing spring, ensuring a reasonable tightness of the cable when it is conveyed through the guiding wheel and the track wheel. A bobbin is slidably connected to the center of the connecting column, and a wire groove for the cable to pass through is provided in the center of the bobbin. A tension spring connected to the top cover on the surface of the bobbin is connected inside the connecting column, enabling the bobbin to limit and press the cable through the tension spring when the cable passes through the track wheel and enters the wire groove, further ensuring the tightness of the cable when it passes through the track wheel and enters the wire groove inside the bobbin. It effectively avoids the situation where the cable is conveyed too loosely and the twisting is not standard or the cable is conveyed too tightly and breaks. The cable can be guided in the corresponding direction and the tightness can be reasonably adjusted through the guiding wheel, the track wheel, and the bobbin during the conveying process, enabling the cable to be straight and stable and fed into the untwisting machine for rotational twisting, ensuring the rotational twisting effect and quality of the cable after it enters the untwisting machine.
[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
