[0001] The present invention relates to the technical field of cable production and processing, and in particular to a tension balancing device and a balance adjustment method for a cable shielding layer wrapping machine. Background Art

[0002] During the cable production and processing, in order to avoid the influence of the magnetic field of crossed or adjacent cables, a circle of copper tape is generally wrapped between the cable core and the protective sheath as a shielding layer to eliminate the influence of the magnetic field. At this time, a copper tape wrapping machine is needed to wrap the copper tape around the cable core.

[0003] During the wrapping operation, as the copper tape on the collection plate gradually decreases, the tension of the tension roller on the copper tape gradually increases, which may cause the copper tape to be over-stretched or even broken, and the uniformity of the wrapping before and after will change. Therefore, in the prior art, a method of winding in small amounts multiple times is often used, which results in the need to frequently install the copper tape on the wrapping machine, seriously affecting production efficiency.

[0024] The present invention provides a tension balancing device and a balance adjustment method for a cable shielding layer wrapping machine, which have the following beneficial effects:

[0025] 1. When the wrapping bin rotates, the fixed gear drives the driven gear 1 to rotate, thereby driving the driving gear 1 to rotate through the rotating shaft 1, and then driving the rack to slide toward the axis center of the wrapping bin inside the fixed box through the driving gear 2, and finally driving the limiting wheel 2 to slide toward the axis center of the wrapping bin through the tension shaft. The driving component and the tension adjusting component in the tension adjusting mechanism cooperate with each other to achieve the goal of maintaining the tension of the copper belt unchanged when the copper belt on the periphery of the collecting disk is reduced, thereby avoiding the situation where the tension of the limiting wheel 2 on the copper belt increases when the copper belt is reduced, causing the copper belt to break.

[0026] 2. When the tension adjustment mechanism adjusts the tension of the copper belt, the second shaft drives the ratchet to rotate, and through the cooperation of the ratchet and the limit spring, drives the pulley three to rotate, thereby driving the pulley four to rotate through the transmission belt two, and then driving the pulley five to rotate through the transmission belt three, and then the fourth shaft drives the eccentric wheel to rotate, so that the right end of the balance shaft can rotate downward, thereby changing the winding angle of the copper belt. Through the one-way transmission component and the angle adjustment component in the balance adjustment mechanism, when the copper belt on the periphery of the collecting disk is reduced, the winding angle of the copper belt can be gradually reduced, so that the copper belt can be evenly wound around the periphery of the cable core wire, avoiding the deviation of the winding angle caused by the reduction of the copper belt on the periphery of the collecting disk, resulting in a gap in the winding and affecting the wrapping quality.

[0027] 3. After the copper tape on the periphery of the collecting tray is used up, replace the collecting tray filled with the copper tape, and press the limiting wheel 2 to disengage the rack from the rotating shaft 2. At the same time, the rack is reset upward by the spring group 2, and the limiting wheel 2 is released. The rack is reset to the right and re-engaged with the rotating shaft 2 through the pulley 1, and then the hexagonal rod is rotated with the hexagonal wrench to drive the rotating shaft 4 to rotate through the bevel gear 2 and the bevel gear 1, and then the balance shaft is reset through the eccentric wheel, so that it is convenient to continue to wrap the copper tape around the periphery of the cable core wire. In addition, through the cooperation of the tension adjustment mechanism and the balance adjustment mechanism, the number of times the copper tape is replaced and installed is reduced when the copper tape is wrapped around the cable core wire at one time, thereby improving the production efficiency of the wrapping.

[0049] In this embodiment, the balance adjustment mechanism 3 includes a one-way transmission component and an angle adjustment component.

[0053] A method for adjusting the tension balance of a cable shielding layer wrapping machine, applied to a tension balancing device of any of the above-mentioned cable shielding layer wrapping machines, comprises the following steps:

[0054] S1. First, after installing the collecting tray 4 and the cable core 6, the copper tape 5 is pulled sequentially through the limiting wheel 210 and the balancing shaft 316 to be wound around the right end of the cable core 6. The winding device of the cable core 6 is started, and the three-phase motor 13 is started at the same time to wind the copper tape 5 around the outer periphery of the cable core 6.

[0055] S2. When the wrapping chamber 18 rotates to wrap the copper tape 5 around the cable core 6, the driving component in the tension adjustment mechanism 2 drives the tension adjustment component to adjust the tension of the copper tape 5 in real time;

[0056] S3. When the tension adjustment mechanism 2 is adjusting the tension of the copper strip 5, the one-way transmission component in the balance adjustment mechanism 3 drives the angle adjustment component to adjust the balance of the copper strip 5 in real time;

[0057] S4. When the copper strip 5 is completely wound, the collecting tray 4 is removed, and the second limiting wheel 210 is pressed to reset the second limiting wheel 210 , and the hexagonal rod 314 is rotated with a hexagonal wrench to reset the balancing shaft 316 ;

[0058] S5. Repeat steps S1-S4 until all the cable core wires 6 are wrapped with the copper tape 5.

[0059] Specifically, after the copper tape 5 on the periphery of the collecting tray 4 is used up, the collecting tray 4 filled with the copper tape 5 is replaced, and the limiting wheel 210 is pressed to disengage the rack 28 from the rotating shaft 26. At the same time, the rack 28 is reset upward by the spring group 213, and the limiting wheel 210 is released. The rack 28 is reset to the right and re-engaged with the rotating shaft 26 through the pulley 1 212. The hexagonal rod 314 is then rotated with a hexagonal wrench to drive the rotating shaft 4 310 to rotate through the bevel gear 2 313 and the bevel gear 1 312, and then the balance shaft 316 is reset through the eccentric wheel 311, so that it is convenient to continue to wrap the copper tape 5 around the periphery of the cable core wire 6. In addition, through the cooperation of the tension adjustment mechanism 2 and the balance adjustment mechanism 3, the number of times the copper tape 5 is replaced and installed is reduced when the copper tape 5 is wrapped around the cable core wire 6 at one time, thereby improving the wrapping production efficiency.

[0060] Working principle: Pass the cable core wire 6 between the upper and lower limiting wheels 110 in the cable drum 19, install the collecting plate 4 to the right outer periphery of the wrapping bin 18, and pass one end of the copper belt 5 through the limiting wheel 210 and the balance shaft 316 in turn to the right end outer periphery of the cable core wire 6, and install the right end of the cable core wire 6 to the traction rope of the winding device, start the winding device, and start the three-phase motor 13 at the same time, drive the pulley 15 to rotate through the speed regulator 14, and then drive the wrapping bin 18 to rotate through the transmission belt 16 and the pulley 2 17, and finally wrap the copper belt 5 around the outer periphery of the cable core wire 6. When the wrapping bin 18 rotates, the fixed gear 21 drives the driven gear 22 to rotate, thereby driving the driving gear 2 through the rotating shaft 23. 4 rotates, and then drives the rack 28 to slide toward the axis center of the wrapping bin 18 inside the fixed box 27 through the driving gear 25, and finally drives the limiting wheel 210 to slide toward the axis center of the wrapping bin 18 through the tension shaft 29. The driving component and the tension adjusting component in the tension adjusting mechanism 2 cooperate with each other to achieve that when the copper strip 5 on the periphery of the collecting tray 4 is reduced, the tension of the copper strip 5 can be kept unchanged, thereby avoiding the situation that when the copper strip 5 is reduced, the tension of the limiting wheel 210 on the copper strip 5 increases, causing the copper strip 5 to break. When the tension adjusting mechanism 2 adjusts the tension of the copper strip 5, the rotating shaft 26 drives the ratchet 31 to rotate, and through the cooperation of the pawl 33 and the limit spring 34, the pulley 3 32 is driven to rotate, thereby The transmission belt 2 35 drives the pulley 4 36 to rotate, and then the transmission belt 38 drives the pulley 5 39 to rotate, and then the rotating shaft 4 310 drives the eccentric wheel 311 to rotate, so that the right end of the balance shaft 316 can rotate downward, thereby changing the winding angle of the copper belt 5. Through the one-way transmission component and the angle adjustment component in the balance adjustment mechanism 3, it is achieved that when the copper belt 5 on the periphery of the collecting tray 4 is reduced, the winding angle of the copper belt 5 can be gradually reduced, so that the copper belt 5 can be evenly wound around the periphery of the cable core 6, avoiding the deviation of the winding angle caused by the reduction of the copper belt 5 on the periphery of the collecting tray 4, resulting in a winding gap and affecting the wrapping quality. After the copper belt 5 on the periphery of the collecting tray 4 is used up, it is replaced with a collecting tray full of copper belt 5. The gear 28 is disengaged from the rotating shaft 26 by pressing the limiting wheel 210, and the rack 28 is reset upward by the spring group 213, and the limiting wheel 210 is released, and the rack 28 is reset to the right and re-engaged with the rotating shaft 26 by the pulley 1 212, and the hexagonal rod 314 is rotated with the hexagonal wrench to drive the rotating shaft 4 310 to rotate by the bevel gear 2 313 and the bevel gear 1 312, and then the balancing shaft 316 is reset by the eccentric wheel 311, so that the copper tape 5 can be continued to be wound around the periphery of the cable core wire 6. In addition, the tension adjustment mechanism 2 and the balance adjustment mechanism 3 cooperate to achieve the copper tape 5 wrapped around the cable core wire 6 at one time, thereby reducing the number of times the copper tape 5 is replaced and installed, thereby improving the production efficiency of the wrapping.
