Description

Technical Field

[0001] The present application relates to the field of cable pay-off, and in particular to a cable untwisting pay-off device. Background Art

[0002] In the cable manufacturing sector, the demand for composite cables is growing with the continuous development of the communications and power industries. Composite cables, due to their inclusion of multiple communication and power cores, can simultaneously meet the transmission needs of different types of signals and power. They play a key role in many fields, including modern infrastructure construction, industrial automation, and intelligent buildings, significantly promoting the informatization and intelligentization of various industries. However, the production process of composite cables is relatively complex, especially the stranding process, which requires the use of multiple payout devices to ensure the orderly payout and stranding of the various cables. This places higher demands on the performance and cost control of the payout devices.

[0003] In traditional cable production, existing payout stands mostly utilize motor-driven devices to achieve cable payout and untwisting operations. The motor provides power, rotating the cable reel to pay out the cable, while precisely controlling the motor to untwist the cable. This approach ensures accuracy and efficiency in payout and untwisting, adapting to the production of cables of varying specifications and requirements. Furthermore, some payout stands are equipped with complex drive and control systems to further optimize the payout process and improve product quality.

[0004] However, existing payout racks use motor-driven devices to pay out and untwist the cables, resulting in high equipment costs. This significantly increases production costs for composite cable production, which requires multiple payout devices, hindering the company's economic benefits and market competitiveness.

A center rod is installed on the cable reel mounting base for the cable reel to be mounted on. The cable reel mounting clamp is detachably connected to the end of the center rod away from the cable reel base to clamp the cable reel mounted on the center rod on the cable reel mounting base.

[0011] By adopting the above technical solution, the guide rod seat is rotatably installed on the cable reel mounting clamp seat, so that the conductor assembly can be rotated circumferentially around the cable reel mounting member. In conjunction with a number of conductor wheels rotatably installed on the conductor rod and a lead-out wheel rotatably installed on the end of the guide rod seat, the cable on the cable reel can be guided and finally led out by the lead-out wheel; the overall structure of the pay-off device is simple, which helps to reduce the purchase or production cost of the pay-off device.

[0012] Preferably, the conductor rod includes a conductor connecting rod and a conductor guide rod, the conductor connecting rod is installed on the guide rod seat, and the conductor guide rod is installed at one end of the conductor connecting rod; a plurality of conductor wheels are rotatably installed on the conductor guide rod to guide the cables on the cable reel to the lead-out wheel and lead them out by the lead-out wheel.

[0013] By adopting the above technical solution, the cable on the cable reel can be effectively guided to the lead-out wheel and led out by the lead-out wheel. In combination with the cable reel mounting part, the circumferentially rotatable conductor assembly and the adjustment assembly for adjusting the cable reel pay-out tension, normal cable pay-out and tension adjustment can be achieved, thereby reducing the purchase or production cost of the pay-out device.

[0014] Preferably, a positioning rod is provided at one end of the wire connecting rod close to the wire guide rod, and the cable on the cable reel enters the wire wheel after passing through the positioning rod, and the wire wheel on the wire guide rod away from the end of the wire connecting rod is in the same plane as the positioning rod.

[0017] This technical solution utilizes the sliding friction between two friction plates to provide tension control. During operation, the upper friction plate and the bearing seat rotate axially simultaneously. When the pay-off tension adjustment dial rotates counterclockwise, the adjustment spring is compressed. This compresses the upper and lower friction plates, increasing friction and, consequently, the pay-off tension. Conversely, when the tension adjustment dial rotates clockwise, the adjustment spring relaxes. This reduces the pressure between the upper and lower friction plates, lowering friction and, consequently, the pay-off tension. This simple adjustment assembly further reduces the purchase or production costs of the pay-off device.

[0018] Preferably, a locking groove is provided on the mounting shaft, and a locking hole is provided on the friction mounting seat. The locking hole is communicated with the locking groove, and a threaded rod is connected to the locking hole. One end of the threaded rod is inserted into the locking groove and abuts against the bottom of the locking groove.

[0019] By adopting the above technical solution, the friction mounting seat and the mounting shaft can be relatively fixed, thereby ensuring that the adjustment component can stably adjust the cable reel pay-off tension, and the purchase or production cost of the pay-off device is reduced due to the simple structure.

During installation, the installation sleeve is put on the installation elastic strip, the positioning protrusion is inserted into the positioning ring groove to achieve preliminary positioning, and then the locking piece is used to lock the elastic deformation of the installation elastic strip to ensure the stable installation of the wire wheel.

[0022] Preferably, the locking piece includes a locking block, a locking groove is provided on the locking block, a locking rod is provided at the bottom of the locking groove, the locking rod passes through the notch of the locking groove at one end away from the bottom of the locking groove, and a tightening elastic soft concave strip is provided between the inner wall of one end of the bottom of the locking groove and the outer edge side wall of the locking rod close to one end of the bottom of the locking groove; several of the installation elastic strips can be inserted into the gap between the inner ring wall of the locking groove and the locking rod, and several of the installation elastic strips are pressed against the tightening elastic soft concave strip, and the locking rod can limit the deformation of several installation elastic strips.

At the same time, the overall device has a simple structure, which can reduce production costs, and is flexible in use and can meet the detwisting function.

[0024] Preferably, a retraction ring is provided at one end of the locking block away from the locking rod, and the ring opening of the retraction ring away from the locking rod is larger than the ring opening of the retraction ring close to the locking rod.

[0025] By adopting the above technical solution, a retraction ring is provided on the locking block and the size of the ring opening changes gradually. When the wire pulley needs to be disassembled, the locking block is changed in direction, so that several installation elastic strips are inserted into the retraction ring.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a cable untwisting and unwinding device.

[0035] Example 1 Reference Figure 1 and Figure 2 The cable untwisting and unwinding device includes a cable drum mounting part 1, on which a cable drum to be unwound is mounted, and the cable drum mounting part 1 is placed on the ground; a conductor assembly 2 is provided on the cable drum mounting part 1, and the conductor assembly 2 can rotate circumferentially around the cable drum mounting part 1; the cable drum mounting part 1 is also provided with an adjustment assembly 3 for adjusting the cable drum unwinding tension.

[0036] The cable reel mounting member 1 is used to place the cable reel to be paid out, and the cable reel mounting member 1 can be placed on the ground; the conductor assembly 2 can rotate circumferentially around the cable reel mounting member 1, which is conducive to the smooth pay-out of the cable; the adjustment assembly 3 can adjust the pay-out tension of the cable reel to ensure the stability of the pay-out process; in summary, the pay-out effect can be achieved without an additional power source, thereby reducing the purchase or production cost of the pay-out device.

[0037] Reference Figure 1 and Figure 2The cable reel mounting part 1 includes a cable reel mounting base 11 and a cable reel mounting clamp 12. The cable reel mounting base 11 can be placed on the ground, and the cable reel mounting base 11 allows a gap between the cable reel and the ground. A center rod 13 is installed on the cable reel mounting base 11. One end of the center rod 13 is fixed to the cable reel mounting base 11, and the center rod 13 is set at the center position of the cable reel mounting base 11. The cable reel is sleeved on the center rod 13, and the bottom of the cable reel contacts the cable reel mounting base 11. The cable reel mounting clamp 12 is detachably connected to the end of the center rod 13 away from the cable reel base, and the cable reel mounting clamp 12 is threadedly connected to the center rod 13.

[0038] The cable reel mounting clamp 12 is screwed onto one end of the center rod 13 away from the cable reel mounting base 11 , thereby clamping the cable reel sleeved on the center rod 13 onto the cable reel mounting base 11 .

[0039] Reference Figure 2 and Figure 3 The cable drum mounting clamp 12 is integrally formed with a mounting shaft 14 at one end away from the cable drum mounting base 11. The mounting shaft 14 extends in a direction away from the center rod 13. The adjustment assembly 3 includes an adjustment disk 31, which is threadedly connected to the mounting shaft 14. A friction mounting seat 35 is also slidably mounted on the mounting shaft 14. The friction mounting seat 35 is located on the side of the adjustment disk 31 away from the cable drum mounting clamp 12. An adjustment spring 32 is installed between the friction mounting seat 35 and the adjustment disk 31. The adjustment spring 32 is sleeved on the mounting shaft 14. A groove for embedding the end of the adjustment spring 32 is preset on the side of the adjustment disk 31 near the adjustment spring 32.

[0040] A locking groove 141 is provided on the mounting shaft 14, and a locking hole 351 is provided on the friction mounting seat 35. The locking hole 351 is communicated with the locking groove 141. A threaded rod is connected to the locking hole 351. One end of the threaded rod is inserted into the locking groove 141 and abuts against the bottom of the locking groove 141.

[0041] A lower friction plate 34 is attached to the end of the friction mount 35 away from the adjustment spring 32 via adhesive bonding. A bearing seat 26 is mounted on the end of the mounting shaft 14 away from the cable drum mounting clamp 12. This bearing seat 26 houses a bearing that is rotatably mounted on the mounting shaft 14. An upper friction plate 33 is attached to the end of the bearing seat 26 near the adjustment spring 32 via adhesive bonding. The upper friction plate 33 rotates synchronously with the bearing seat 26, allowing it to abut against the lower friction plate 34.

[0042] During operation, the upper friction plate 33 and the bearing seat 26 rotate axially simultaneously. When the payout tension adjustment dial 31 rotates counterclockwise, the adjustment spring 32 is compressed. This compresses the upper friction plate 33 and the lower friction plate 34, increasing friction and the payout tension. Conversely, when the tension adjustment dial 31 rotates clockwise, the adjustment spring 32 relaxes. The pressure between the upper friction plate 33 and the lower friction plate 34 decreases, reducing friction and, consequently, the payout tension.

[0043] Reference Figure 2 and Figure 3 The wire assembly 2 is arranged at one end of the mounting shaft 14 away from the cable drum mounting clamp 12. The wire assembly 2 includes a guide rod seat 21. The guide rod seat 21 is fixed to the end of the bearing seat 26 away from the adjusting disk 31 by bolts. The guide rod seat 21 rotates synchronously with the bearing seat 26.

[0044] A wire rod 22 is installed on the guide rod seat 21. The wire rod 22 includes a wire connecting rod 221 and a wire guide rod 222. The wire connecting rod 221 is installed on the guide rod seat 21, wherein the wire connecting rod 221 is passed through the guide rod seat 21, and for balance, the length of the wire connecting rod 221 on both sides of the guide rod seat 21 is consistent.

[0045] The wire guide rod 222 is installed on one end of the wire connecting rod 221 by means of bolts. At this time, the plane in which the wire guide rod 222 and the wire connecting rod 221 are located has an inclination angle with the vertical plane, that is, the virtual extension line of the wire guide rod 222 has an angle less than 90° with the ground. Several wire wheels 24 are installed on the wire guide rod 222.

[0046] A positioning rod 223 is provided at one end of the wire connecting rod 221, near the wire guide rod 222. In this embodiment, the positioning rod 223 and the wire connecting rod 221 lie in a vertical plane, meaning that the virtual extension of the positioning rod 223 is perpendicular to the ground. The wire pulley 24 on the end of the wire guide rod 222, located away from the wire connecting rod 221, lies in the same vertical plane as the positioning rod 223. This means that the circumferential plane of the wire pulley 24 is also perpendicular to the ground. After passing through the positioning rod 223, the cable on the cable drum enters the wire pulley 24, which then guides the cable on the drum.

[0047] For balance, in the embodiment of the present application, a straight rod similar to the positioning rod 223 can be set at one end of the wire connecting rod 221 away from the wire guiding rod 222 for balance. A roller 2231 is rotatably sleeved on the positioning rod 223 to reduce friction of the cable.

[0048] In this embodiment, a through slot is provided on the guide rod seat 21, a steering wheel 25 is installed at the through hole of the guide rod seat 21, and a lead-out wheel 23 is installed at one end of the guide rod seat 21 away from the cable drum mounting clamp seat 12. A through hole is provided on the top of the guide rod seat 21, and the through hole is connected to the through slot.

[0049] The cable enters the deflection wheel 25 after the guide wheel 24 is guided, and enters the lead-out wheel 23 after the deflection wheel 25 turns to, and is finally drawn by the lead-out wheel 23. In the present embodiment, the cable portion that enters the lead-out wheel 23 after the deflection wheel 25 turns to is a vertical state.

[0050] The working principle of Example 1 is as follows: the cable drum mounting clamp 12 is unscrewed from the center rod 13. The operator hoists the cable drum to the top of the center rod 13 using a lifting device and slowly lowers the cable drum. The cable drum is now sleeved onto the center rod 13. The operator then re-screws the cable drum mounting clamp 12 onto the center rod 13 to clamp the cable drum. The cable end is passed through a plurality of guide pulleys 24 and is drawn out through a steering pulley 25 and a lead-out pulley 23 for payout. Overall, the payout device in this embodiment achieves the payout effect without the need for an additional power source. The simple structure achieves the payout function, thereby reducing the purchase or production cost of the payout device.

[0051] Example 2 Reference Figure 4 and Figure 5 The cable untwisting and unwinding device further includes a plurality of mounting assemblies 4 disposed on the conductor rod 22, and the conductor pulley 24 is removably mounted on the mounting assemblies 4. The mounting assemblies 4 include a plurality of elastic mounting strips 42. In this embodiment, the elastic mounting strips 42 are made of metal or stainless steel. Metal or stainless steel elastic mounting strips 42 are elastic while maintaining a certain degree of hardness. One end of each of the elastic mounting strips 42 is mounted on the conductor rod 22. In this embodiment, one end of each of the elastic mounting strips 42 is fixed to the conductor guide rod 222 by welding. The multiple elastic mounting strips 42 of each mounting assembly 4 form a virtual circle, and gaps exist between adjacent elastic mounting strips 42.

[0052] In order to cooperate with multiple mounting elastic strips 42, a mounting sleeve 241 is integrally formed in the center of the wire wheel 24. The mounting sleeve 241 is a stainless steel structure and can be mounted on several mounting elastic strips 42; positioning protrusions 421 are integrally formed on the outer sides of several mounting elastic strips 42. The positioning protrusions 421 are arc-shaped protrusions. A positioning ring groove 242 is provided on the inner ring side of the mounting sleeve 241. Several positioning protrusions 421 can be inserted into the positioning ring groove 242, and the wire wheel 24 can rotate around several positioning protrusions 421.

[0053] When the wire pulley 24 is mounted on the plurality of mounting elastic strips 42 and the plurality of positioning protrusions 421 are inserted into the positioning ring grooves 242, in order to prevent the wire pulley 24 from falling off the mounting elastic strips 42, a locking member 41 is provided at one end of the plurality of elastic strips away from the wire guide rod 222 to lock the elastic deformation of the plurality of mounting elastic strips 42.

[0054] The locking piece 41 includes a locking block 411, which is provided with a locking groove 4111. A locking rod 412 is integrally formed at the bottom of the locking groove 4111. The end of the locking rod 412 away from the bottom of the locking groove 4111 passes through the notch of the locking groove 4111. A tightening elastic soft groove strip 413 is provided between the inner wall of one end of the bottom of the locking groove 4111 and the outer edge side wall of the locking rod 412 close to one end of the bottom of the locking groove 4111. The tightening elastic soft groove strip 413 is made of rubber, and is fixed to the bottom of the locking groove 4111 by gluing.

[0055] Several installation elastic strips 42 can be inserted into the gap between the inner ring wall of the locking groove 4111 and the locking rod 412. At this time, the end of the installation elastic strip 42 is inserted into the elastic soft concave strip 413, and the side walls of the installation elastic strip 42 are respectively limited by the inner wall of the locking groove 4111 and the locking rod 412, so that the locking rod 412 limits the deformation of several installation elastic strips 42.

[0056] A retraction ring 414 is integrally formed at one end of the locking block 411 away from the locking rod 412. The opening of the retraction ring 414 away from the locking rod 412 is larger than the opening of the retraction ring 414 close to the locking rod 412, that is, the inner wall of the retraction ring 414 forms a guiding slope.

[0057] The implementation principle of Example 2 is as follows: for cables of different sizes, it is necessary to replace the appropriate wire pulley 24 for wire routing. At this time, the wire pulley 24 is sleeved on the end of the installation elastic strip 42 and slides to the positioning protrusion. The wire pulley 24 is finally installed on the installation elastic strip 42. The locking block 411, the locking rod 412 and the elastic soft concave strip 413 cooperate to allow the installation elastic strip 42 to be inserted and tightened therein. The locking rod 412 is used to limit the deformation of the installation elastic strip 42. When it is necessary to remove the wire pulley 24, the locking block is changed in direction, so that several installation elastic strips 42 are inserted into the retraction ring 414. The inner wall of the retraction ring 414 acts as a guide to deform the several installation elastic strips 42, thereby facilitating the separation of the installation sleeve 241 of the wire pulley 24 from the installation elastic strip 42, thereby improving the convenience of removing the wire pulley 24.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
