Description

Technical Field

[0001] The present invention relates to the technical field of cable production and processing, and particularly relates 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 process, in order to avoid the magnetic field influence of crossed or adjacent cables, generally a copper tape is wound around the cable core wire and the protective sheath as a shielding layer to eliminate the magnetic field influence. At this time, a copper tape wrapping machine is required to wind the copper tape onto the cable core wire.

[0003] During the wrapping operation, as the copper tape on the collecting disk gradually decreases, the tension of the copper tape by the tension roller gradually increases, which may cause the copper tape to be stretched excessively or even broken, and the uniformity of the front and back wrapping will change. Therefore, in the prior art, the method of winding in small amounts and multiple times is often used, resulting in the need to frequently install the copper tape onto the wrapping machine, seriously affecting the production efficiency.

[0018] A method for adjusting the tension balance of a cable shielding layer wrapping machine is applied to the tension balance device of a cable shielding layer wrapping machine described in any one of the above. The method includes the following steps:

[0019] S1. First, after installing the collecting disc and the cable core wire, the copper tape is tractioned through the second limiting wheel and wound around the balance shaft in sequence to the outer periphery of the right end of the cable core wire. The winding device of the cable core wire is started, and at the same time, the three-phase motor is started to wind the copper tape around the outer periphery of the cable core wire.

[0020] S2. When the wrapping bin rotates to wind the copper tape around the cable core wire, the driving assembly in the tension adjusting mechanism drives the tension adjusting assembly to adjust the tension of the copper tape in real time.

[0021] S3. When the tension adjusting mechanism adjusts the tension of the copper tape, the one-way transmission assembly in the balance adjusting mechanism drives the angle adjusting assembly to adjust the balance of the copper tape in real time.

[0022] S4. When the copper tape is completely wound, the collecting disc is removed, and the second limiting wheel is pressed to make the second limiting wheel reset, and the hexagonal rod is rotated by a hexagonal wrench to make the balance shaft reset.

[0023] S5. Repeat steps S1 - S4 until all the outer peripheries of the cable core wires are wound with copper tape.

[0024] The beneficial effects of the tension balance device and the balance adjustment method of a cable shielding layer wrapping machine provided by the present invention are as follows:

[0025] 1. When the wrapping bin rotates, the driven gear one is driven to rotate by the fixed gear, so that the driving gear one is driven to rotate by the first rotating shaft, and then the rack is driven to slide towards the axis of the wrapping bin inside the fixed box by the driving gear two. Finally, the second limiting wheel is driven to slide towards the axis of the wrapping bin by the tension shaft. Through the mutual cooperation of the driving assembly and the tension adjusting assembly in the tension adjusting mechanism, when the copper tape on the outer periphery of the collecting disc decreases, the tension of the copper tape can be kept unchanged, and further, when the copper tape decreases, the situation that the tension of the copper tape becomes too large by the second limiting wheel and causes the copper tape to break can be avoided.

[0026] 2. When the tension adjustment mechanism adjusts the tension of the copper strip, the second rotating shaft drives the ratchet wheel to rotate. Through the cooperation of the ratchet pawl and the limit spring, the third pulley is driven to rotate, thereby driving the fourth pulley to rotate through the second transmission belt, and then driving the fifth pulley to rotate through the third transmission belt. Furthermore, the fourth rotating shaft drives the eccentric wheel to rotate, enabling the right end of the balance shaft to rotate downward, and further causing the winding angle of the copper strip to change. Through the one-way transmission component and the angle adjustment component in the balance adjustment mechanism, when the copper strip on the outer periphery of the collecting disc decreases, the winding angle of the copper strip can be gradually reduced, enabling the copper strip to be evenly wound around the outer periphery of the cable core wire, and preventing the winding angle from deviating when the copper strip on the outer periphery of the collecting disc decreases, resulting in gaps in the winding and affecting the wrapping quality.

[0027] 3. After the copper strip on the outer periphery of the collecting disc is used up, replace it with a collecting disc fully loaded with copper strip, and press the second limit wheel to disengage the rack from the second rotating shaft. At the same time, the rack is reset upward through the second spring group. Release the second limit wheel, and the rack is reset to the right through the first pulley to re-engage with the second rotating shaft. Then use a hex wrench to rotate the hexagon rod, driving the fourth rotating shaft to rotate through the second bevel gear and the first bevel gear, and further resetting the balance shaft through the eccentric wheel. This facilitates the subsequent winding of the copper strip around the outer periphery of the cable core wire, and through the cooperation of the tension adjustment mechanism and the balance adjustment mechanism, the number of times of replacing and installing the copper strip is reduced during the single-time wrapping of the copper strip around the cable core wire, improving the production efficiency of the wrapping.

[0042] In this embodiment, the lower end of the speed regulator 14 is fixedly connected to the left end of the lower inner side of the workbench 11. The inner circumference of the second pulley 17 is fixedly connected to the outer circumference of the wrapping chamber 18. The outer circumference of the wrapping chamber 18 is rotatably connected to the middle part of the control chamber 12. At the outer circumference of the right end of the wrapping chamber 18, a collecting disc 4 is fixedly installed. Around the outer circumference of the collecting disc 4, a copper strip 5 is wound. The right end of the copper strip 5 is wound around the outer circumference of the right end of the cable core 6.

[0043] Specifically, pass the cable core 6 through the first limiting wheels 110 inside the cable drum 19. Install the collecting disc 4 on the outer circumference of the right side of the wrapping chamber 18. Pass one end of the copper strip 5 through a second limiting wheel 210 and a balance shaft 316 in sequence and wind it around the outer circumference of the right end of the cable core 6. Install the right end of the cable core 6 on the towing rope of the winding device. Start the winding device and at the same time start the three-phase motor 13. Drive the first pulley 15 to rotate through the speed regulator 14, and then drive the wrapping chamber 18 to rotate through the first transmission belt 16 and the second pulley 17. Finally, wind the copper strip 5 around the outer circumference of the cable core 6.

[0044] In this embodiment, the tension adjusting mechanism 2 includes a driving component and a tension adjusting component. The tension adjusting component includes a fixed box 27. Inside the fixed box 27, on the upper right side, a rack 28 is slidably connected. At the upper right end of the rack 28, a tension shaft 29 is fixedly connected. Around the outer circumference of the right end of the tension shaft 29, a second limiting wheel 210 is rotatably connected. On the left end of the rack 28, a first spring group 211 is evenly distributed. The left ends of the first spring group 211 are all fixedly connected with first pulleys 212. At the lower end of the rack 28, a second spring group 213 is fixedly connected. The lower end of the second spring group 213 is fixedly connected with second pulleys 214.

[0045] In this embodiment, the left ends of the first pulleys 212 are all slidably connected to the left inner side of the fixed box 27. The lower ends of the second pulleys 214 are slidably connected to the lower inner side of the fixed box 27. Around the outer circumference of the left end of the tension shaft 29, it is slidably connected to the opening on the upper right side of the fixed box 27.

[0046] In this embodiment, the driving assembly includes a fixed gear 21. The inner circumference of the fixed gear 21 is fixedly connected to the outer circumference of the cable drum 19. The fixed gear 21 is meshed with a first driven gear 22. A first rotating shaft 23 is fixedly connected to the middle of the first driven gear 22. A first driving gear 24 is fixedly connected to the outer circumference of the right side of the first rotating shaft 23. The first driving gear 24 is meshed with a second driving gear 25. A second rotating shaft 26 is fixedly connected to the middle of the second driving gear 25. The second driving gear 25 is meshed with a rack 28.

[0047] In this embodiment, the left ends of the first rotating shaft 23 and the second rotating shaft 26 are both rotatably connected to the front end on the left side inside the control bin 12 through limit bearing seats, and the right end of the first driven gear 22 is rotatably connected to the front end on the right side inside the wrapping bin 18.

[0048] Specifically, when the wrapping bin 18 rotates, the first driven gear 22 is driven to rotate by the fixed gear 21, so that the first driving gear 24 is driven to rotate through the first rotating shaft 23, and then the rack 28 is driven to slide towards the axis of the wrapping bin 18 inside the fixed box 27 through the second driving gear 25. Finally, the second limiting wheel 210 is driven to slide towards the axis of the wrapping bin 18 through the tension shaft 29. Through the mutual cooperation of the driving assembly and the tension adjusting assembly in the tension adjusting mechanism 2, it is realized that when the copper strip 5 on the outer circumference of the collecting disc 4 decreases, the tension on the copper strip 5 can be kept unchanged, and further, when the copper strip 5 decreases, the situation that the tension of the copper strip 5 becomes too large due to the second limiting wheel 210 and the copper strip 5 breaks is avoided.

[0049] In this embodiment, the balance adjusting mechanism 3 includes a one-way transmission assembly and an angle adjusting assembly. The angle adjusting assembly includes a fourth rotating shaft 310 and a rotating bin 315. A balance shaft 316 is rotatably connected inside the rotating bin 315. An eccentric wheel 311 is fixedly connected to the right side in the middle of the fourth rotating shaft 310. The lower end of the eccentric wheel 311 is in contact with the upper side of the left end of the balance shaft 316. A first bevel gear 312 is fixedly connected to the outer circumference of the right end of the fourth rotating shaft 310. The first bevel gear 312 is meshed with a second bevel gear 313. A hexagonal rod 314 is fixedly connected to the middle of the second bevel gear 313.

[0050] In this embodiment, the one-way transmission assembly includes a ratchet wheel 31. The inner circumference of the ratchet wheel 31 is fixedly connected to the outer circumference of the middle of the second rotating shaft 26. A third pulley 32 is rotatably connected to the outer circumference of the ratchet wheel 31. Pawls 33 are evenly distributed inside the third pulley 32. A limit spring 34 is fixedly connected to the side of each pawl 33 away from the ratchet wheel 31. The limit spring 34 is connected to a fourth pulley 36 through a second transmission belt 35. A third rotating shaft 37 is fixedly connected to the middle of the fourth pulley 36. The fourth pulley 36 is connected to a fifth pulley 39 through a third transmission belt 38. The inner circumference of the fifth pulley 39 is fixedly connected to the outer circumference of the left end in the middle of the fourth rotating shaft 310.

[0051] In this embodiment, the left ends of the fourth rotating shaft 310 and the third rotating shaft 37 are both rotatably connected to the upper left inside of the control bin 12 through limit bearing seats. The pawls 33 are all engaged with the ratchets 31, and one ends of the limit springs 34 far away from the ratchets 31 are fixedly connected to the inside of the third pulley 32.

[0052] Specifically, when the tension adjusting mechanism 2 adjusts the tension of the copper strip 5, the second rotating shaft 26 drives the ratchet 31 to rotate. Through the cooperation of the pawl 33 and the limit spring 34, the third pulley 32 is driven to rotate, so that the fourth pulley 36 is driven to rotate through the second transmission belt 35, and then the fifth pulley 39 is driven to rotate through the third transmission belt 38. Furthermore, the fourth rotating shaft 310 drives the eccentric wheel 311 to rotate, so that the right end of the balance shaft 316 can rotate downward, and then the winding angle of the copper strip 5 changes. Through the one-way transmission assembly and the angle adjustment assembly in the balance adjustment mechanism 3, when the copper strip 5 on the outer periphery of the collecting disc 4 decreases, the winding angle of the copper strip 5 can be gradually reduced, so that the copper strip 5 can be evenly wound around the outer periphery of the cable core wire 6, avoiding deviation of the winding angle when the copper strip 5 on the outer periphery of the collecting disc 4 decreases, resulting in gaps in the winding and affecting the winding quality.

[0053] A method for adjusting the tension balance of a cable shielding layer wrapping machine is applied to the tension balance device of a cable shielding layer wrapping machine in any one of the above, and includes the following steps:

[0054] S1. First, after installing the collecting disc 4 and the cable core wire 6, the copper strip 5 is drawn through the second limit wheel 210 and the balance shaft 316 in sequence and wound around the right end outer periphery of the cable core wire 6. The winding device of the cable core wire 6 is started, and at the same time, the three-phase motor 13 is started to wind the copper strip 5 around the outer periphery of the cable core wire 6.

[0055] S2. When the wrapping bin 18 rotates to wind the copper strip 5 around the cable core wire 6, the driving assembly in the tension adjusting mechanism 2 drives the tension adjusting assembly to adjust the tension of the copper strip 5 in real time.

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

[0057] S4. When the copper strip 5 is completely wound, the collecting disc 4 is removed, and the second limit wheel 210 is pressed to reset the second limit wheel 210, and the balance shaft 316 is reset by rotating the hexagonal rod 314 with a hexagonal wrench.

[0058] S5. Repeat steps S1 - S4 until the outer peripheries of all the cable core wires 6 are wound with the copper strip 5.

[0059] Specifically, after the copper strip 5 on the outer periphery of the collecting disc 4 is used up, replace the collecting disc 4 fully loaded with the copper strip 5, and press the second limiting wheel 210 so that the rack 28 disengages from the second rotating shaft 26. At the same time, the rack 28 is reset upward through the second spring group 213. Release the second limiting wheel 210, and the rack 28 is reset to the right through the first pulley 212 to re-engage with the second rotating shaft 26. Then use a hex wrench to rotate the hexagon rod 314, drive the fourth rotating shaft 310 to rotate through the second bevel gear 313 and the first bevel gear 312, and further reset the balance shaft 316 through the eccentric wheel 311, facilitating the subsequent continuous winding of the copper strip 5 around the outer periphery of the cable core wire 6. And through the cooperation of the tension adjusting mechanism 2 and the balance adjusting mechanism 3, when the copper strip 5 is wound around the cable core wire 6 at one time, the number of times of replacing and installing the copper strip 5 is reduced, and the production efficiency of winding is improved.

[0060] Working principle: Pass the cable core wire 6 through the upper and lower limiting wheels 110 inside the cable drum 19. Install the collecting disc 4 on the outer periphery of the right side of the wrapping bin 18. Pass one end of the copper tape 5 through the limiting wheel 210 and the balance shaft 316 in sequence and wind it around the outer periphery of the right end of the cable core wire 6. Install the right end of the cable core wire 6 on the traction rope of the winding device. Start the winding device and at the same time start the three-phase motor 13. Drive the pulley 15 to rotate through the speed governor 14, and then drive the wrapping bin 18 to rotate through the transmission belt 16 and the pulley 17. Finally, wind the copper tape 5 around the outer periphery of the cable core wire 6. When the wrapping bin 18 rotates, drive the driven gear 22 to rotate through the fixed gear 21, thereby drive the driving gear 24 to rotate through the rotating shaft 23, and then drive the rack 28 to slide towards the axis of the wrapping bin 18 inside the fixed box 27 through the driving gear 25. Finally, drive the limiting wheel 210 to slide towards the axis of the wrapping bin 18 through the tension shaft 29. Through the mutual cooperation of the driving component and the tension adjusting component in the tension adjusting mechanism 2, when the copper tape 5 on the outer periphery of the collecting disc 4 decreases, the tension of the copper tape 5 can be maintained without change, thereby avoiding the situation that when the copper tape 5 decreases, the tension of the copper tape 5 by the limiting wheel 210 becomes too large and causes the copper tape 5 to break. When the tension adjusting mechanism 2 adjusts the tension of the copper tape 5, the rotating shaft 26 drives the ratchet wheel 31 to rotate. Through the cooperation of the ratchet pawl 33 and the limiting spring 34, drive the pulley 32 to rotate, thereby drive the pulley 36 to rotate through the transmission belt 35, and then drive the pulley 39 to rotate through the transmission belt 38. Furthermore, the rotating shaft 310 drives the eccentric wheel 311 to rotate, so that the right end of the balance shaft 316 can rotate downward, and then the winding angle of the copper tape 5 changes. Through the one-way transmission component and the angle adjusting component in the balance adjusting mechanism 3, when the copper tape 5 on the outer periphery of the collecting disc 4 decreases, the winding angle of the copper tape 5 can be gradually reduced, so that the copper tape 5 can be evenly wound around the outer periphery of the cable core wire 6, avoiding the deviation of the winding angle when the copper tape 5 on the outer periphery of the collecting disc 4 decreases and causing gaps in the winding, which affects the wrapping quality. After the copper tape 5 on the outer periphery of the collecting disc 4 is used up, replace it with a collecting disc 4 full of copper tape 5, and press the limiting wheel 210 to make the rack 28 disengage from the rotating shaft 26. At the same time, the rack 28 is reset upward through the spring group 213. Release the limiting wheel 210, and the rack 28 is reset to the right through the pulley 212 and engages with the rotating shaft 26 again. Then use a hex wrench to rotate the hexagon rod 314, drive the rotating shaft 310 to rotate through the bevel gear 313 and the bevel gear 312, and then the balance shaft 316 is reset through the eccentric wheel 311, which is convenient for subsequent winding of the copper tape 5 around the outer periphery of the cable core wire 6. And through the cooperation of the tension adjusting mechanism 2 and the balance adjusting mechanism 3, when wrapping the copper tape 5 around the cable core wire 6 once, the number of times of replacing and installing the copper tape 5 is reduced, and the production efficiency of wrapping is improved.
