Description

Technical Field

[0001] The present invention relates to the technical field of cable production, in particular to a backtwisting pay-off frame for cable production. Background Art

[0002] In today's cable production sector, with the rapid development of industries like electronic equipment and power transmission, the market demands increasingly stringent quality and performance for cables. The backtwist process is crucial in cable production, and the precision of its operation directly impacts the final quality of the cable.

[0003] Traditional cable detwisting and payoff equipment has numerous technical limitations. For one thing, most detwisting devices utilize a simple single-motor drive, which makes it difficult to precisely control the detwisting speed and torque. In actual production, the unstable power output of the motor results in uneven torque applied to the cable during the detwisting process. For example, when producing communications cables with extremely high torsional requirements, unstable torque can cause distortion and deformation within the cable structure, severely impacting its electrical performance. Signal transmission is susceptible to attenuation and interference, resulting in low product yields and an inability to meet market demand for high-quality cables. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a detwisting pay-off frame for cable production, which solves the problem that traditional cable detwisting pay-off equipment is difficult to ensure the accuracy of detwisting and the quality of the produced cables is difficult to meet unified standards.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a detwisting pay-off frame for cable production, comprising an outer shell, an upper inner wall of the outer shell is rotatably connected to a flip plate 1, an outer wall of the flip plate 1 is fixedly connected to a handle, a lower surface of the flip plate 1 is fitted with a flip plate 2, an outer wall of the flip plate 2 is rotatably connected to the lower inner wall of the outer shell, a buffer pad is fixedly connected to the lower surface of the outer shell, a control center is fixedly connected to the outer wall of the outer shell, a collecting tank is provided inside the lower side of the outer shell, a wire-paying detwisting assembly, a fixed block and a support assembly are fixedly connected to the inner bottom wall of the outer shell, a fan blade is provided on the right outer wall of the wire-paying detwisting assembly, and a connecting assembly is fixedly connected to the outer wall of the outer shell.

[0006] By adopting the above technical solution, the shell serves as the main structure of the entire pay-off frame, providing stable installation space and protection for the internal components, and can resist interference from external environmental factors on the internal precision components; the flip plate 1 and the flip plate 2 are combined with the handle to facilitate the operator to open and close the pay-off frame, facilitate the installation and debugging of cables, and inspect and maintain the internal components, thereby improving the convenience of equipment use; the buffer pad on the lower surface of the shell can effectively reduce the vibration generated when the pay-off frame is working, avoid the cable detwisting accuracy deviation caused by vibration, and at the same time reduce the equipment operation noise and optimize the working environment; the connecting ring 1 is driven to rotate by a double-headed motor, and the connecting ring 1 causes the connecting ring 2 to rotate synchronously through the belt, thereby driving the connecting rod and the mounting seat to rotate, thereby realizing cable detwisting, effectively ensuring that the quality of the produced cables is stable and meets the standards, and improving the reliability and consistency of the product.

[0007] Preferably, the line-releasing and detwisting assembly includes a double-headed motor, the outer wall of the double-headed motor is fixedly connected to the inner bottom wall of the outer shell, one side output end of the double-headed motor is connected to a support block, the other side output end of the double-headed motor is connected to connecting ring one, the connecting ring one is connected to connecting ring two through a belt, the outer wall of connecting ring two is fixedly connected to a gear assembly, the interior of the gear assembly is fixedly connected to a connecting rod, the outer wall of the connecting rod is rotatably connected to the inner wall of the fixed block, and the outer wall of the connecting rod is fixedly connected to a mounting seat.

[0008] Preferably, the gear assembly includes a ring gear, the outer wall of which is fixedly connected to the outer wall of connecting ring 2, the tooth end of the ring gear is meshedly connected to the first gear, the tooth end of the first gear is connected to the second gear, and the outer wall of the second gear is fixedly connected to the outer wall of the connecting rod.

[0009] Preferably, the inner wall of the fan blade is fixedly connected to the right outer wall of the connecting ring 1.

[0010] Preferably, the support assembly includes a fixed plate, the lower surface of the fixed plate is fixedly connected to the inner bottom wall of the shell, the outer wall of the fixed plate is fixedly connected to an electric push rod, the output end of the electric push rod is connected to sliding plate 1, the upper surface of sliding plate 1 is fixedly connected to sliding plate 2, the outer wall of sliding plate 2 is rotatably connected to wheel 1, and the outer wall of wheel 1 is fixedly connected to a limiting ring.

[0011] Preferably, the connecting assembly includes a fixing rod 1, the outer wall of the fixing rod 1 is fixedly connected to the outer wall of the outer shell, the upper surface of the fixing rod 1 is fixedly connected to the fixing rod 2, the upper surface of the fixing rod 2 is rotatably connected to the rotating wheel 2, and a slide groove is opened inside the outer shell, and the slide groove cooperates with the rotating wheel 2 to realize smooth guiding of the cable.

[0012] Preferably, the control center is equipped with a tension sensor and a PLC controller, and the PLC controller is electrically connected to the double-headed motor and the electric push rod for real-time monitoring and adjustment of the cable tension and back-twisting speed.

[0013] Preferably, an elastic buffer layer is provided between the first flip plate and the second flip plate, and the elastic buffer layer is made of rubber.

[0014] Preferably, a detachable filter is provided at the bottom of the collecting tank, the aperture of the filter is smaller than the diameter of the cable, and is used to collect debris that falls off during the untwisting process.

[0015] Preferably, a transparent observation window is provided on the outer wall of the flip plate 1, and the observation window is made of high-temperature resistant tempered glass to facilitate real-time monitoring of the internal cable status.

[0016] Working principle: First, hold the handle on the flip plate one and flip it upwards. After placing the cable on the mounting seat of the pay-off and back-twist assembly, lower the flip plate one so that its lower surface fits with the flip plate two to complete the initial fixation of the cable.

[0017] The control center is activated, and its built-in tension sensor begins monitoring the cable tension in real time and transmits the data to the PLC controller. The PLC controller controls the operation of the double-headed motor based on the preset tension value and detwist speed parameters. One output end of the double-headed motor drives the support block to rotate, while the other output end drives connecting ring 1. Connecting ring 1 is connected to connecting ring 2 via a belt, which drives connecting ring 2 to rotate synchronously. The ring gear fixed to the outer wall of connecting ring 2 rotates accordingly. The ring gear meshes with the first gear, driving the first gear to rotate, which in turn drives the second gear connected to it. The second gear is fixed to the outer wall of the connecting rod, which in turn rotates the connecting rod and the mounting base, achieving the detwist operation of the cable.

[0018] During the back-twisting process, the electric push rod extends and retracts according to the command of the control center. When the electric push rod extends, it pushes the sliding plate 1 to rise, and the sliding plate 1 drives the sliding plate 2 to rise, so that the rotating wheel 1 contacts the cable and provides supporting force. The limit ring on the outer wall of the rotating wheel 1 can prevent the cable from deviating during the support process.

[0019] During the untwisting and pay-off process, the cable passes through the second wheel and the slide groove opened inside the shell to achieve smooth guidance. At the same time, the debris that falls off during the untwisting process will fall into the collection tank. The bottom of the collection tank is equipped with a detachable filter with an aperture smaller than the cable diameter, which can effectively collect debris and keep the working environment clean.

[0020] The present invention provides a backtwist pay-off stand for cable production, which has the following beneficial effects: 1. The present invention drives the connecting ring 1 to rotate through a double-headed motor, and the connecting ring 1 causes the connecting ring 2 to rotate synchronously through a belt. The gear ring on the connecting ring 2 drives the first gear and the second gear, and then drives the connecting rod and the mounting seat to rotate, thereby realizing cable detwisting, effectively ensuring that the quality of the produced cables is stable and meets the standards, improving the reliability and consistency of the products, reducing the cable quality problems caused by inaccurate detwisting, and improving the market competitiveness of the products.

[0021] 2. The present invention drives the fan blades to rotate when the connecting ring rotates, which can cool the double-headed motor and reduce the temperature of the motor during long-term operation, helping to extend the service life of the motor, reduce the frequency of equipment failures, reduce maintenance costs, improve production efficiency, and ensure the continuity of the production process.

[0022] 3. The outer wall of the rotating wheel in the support assembly of the present invention is fixed with a limiting ring. During the production process, the limiting ring can effectively limit the lateral displacement of the cable, ensuring that the cable always remains in the correct position during the untwisting and pay-off operations, preventing the cable from deviating from the predetermined trajectory, improving the accuracy and stability of cable production, ensuring the consistency of product quality, reducing production accidents and product defects caused by cable deviation, and further improving product quality and production safety.

[0023] 4. A detachable filter screen is provided at the bottom of the collection tank of the present invention, and its aperture is smaller than the cable diameter. It can effectively collect debris generated by friction of the cable during the back-twisting process, avoid debris scattering around the equipment, keep the production environment clean, reduce the cleaning cost caused by debris contaminating the production site, and prevent debris from mixing into other production links to affect product quality, thereby maintaining the hygiene of the production environment and the standardization of the production process.

[0026] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see the attached Figure 1 -Attached Figure 3 An embodiment of the present invention provides a detwisting pay-off frame for cable production, comprising a shell 1, an upper inner wall of the shell 1 being rotatably connected to a flip plate 2, an outer wall of the flip plate 2 being fixedly connected to a handle 3, a lower surface of the flip plate 2 being fitted with a flip plate 2, an outer wall of the flip plate 2 4 being rotatably connected to the lower inner wall of the shell 1, a buffer pad 5 being fixedly connected to the lower surface of the shell 1, a control center 6 being fixedly connected to the outer wall of the shell 1, a collecting tank 7 being provided inside the lower side of the shell 1, a pay-off detwisting assembly 8, a fixing block 9 and a supporting assembly 11 being fixedly connected to the inner bottom wall of the shell 1, a fan blade 10 being provided on the right outer wall of the pay-off detwisting assembly 8, and a connecting assembly 12 being fixedly connected to the outer wall of the shell 1.

[0028] Specifically, first, grasp the handle 3 on flip plate 1 (2) and flip it upward. After placing the cable on the pay-off and untwisting assembly 8, lower flip plate 1 (2) so that its lower surface is in contact with flip plate 2 (4), completing the initial cable fixation. The control center 6 activates the pay-off and untwisting assembly 8 to untwist the cable. During the untwisting process, the support assembly 11 extends and retracts according to the control center 6's instructions, contacting and providing support. Debris that falls off during the untwisting process falls into the collection trough 7, effectively collecting the debris and maintaining a clean working environment. Finally, the cable passes through the connection assembly 12 to the next process.

[0029] Please see the attached Figure 3 -Attached Figure 5The unwinding assembly 8 includes a double-headed motor 81, the outer wall of the double-headed motor 81 is fixedly connected to the inner bottom wall of the outer shell 1, one side output end of the double-headed motor 81 is connected to the support block 82, the other side output end of the double-headed motor 81 is connected to the connecting ring 1 83, the connecting ring 1 83 is connected to the connecting ring 2 84 through a belt, the outer wall of the connecting ring 2 84 is fixedly connected to the gear assembly 85, the interior of the gear assembly 85 is fixedly connected to the connecting rod 86, the outer wall of the connecting rod 86 is rotatably connected to the inner wall of the fixed block 9, and the outer wall of the connecting rod 86 is fixedly connected to the mounting seat 87; the inner wall of the fan blade 10 is fixedly connected to the right outer wall of the connecting ring 1 83.

[0030] Specifically, when the entire pay-off rack begins operation, the control center 6 issues a start command to the double-headed motor 81. The double-headed motor 81 is fixed to the inner bottom wall of the housing 1, providing a stable power source for the entire assembly. After startup, one output end of the double-headed motor 81 drives the support block 82 to rotate. The rotation of the support block 82 is not directly used for cable detwisting, but is used to reduce vibration and deviation caused by unilateral force, making the equipment run more smoothly and reliably. The output end of the other side of the double-headed motor 81 drives the connecting ring 1 83 to rotate synchronously. The connecting ring 1 83 is connected to the connecting ring 2 84 by a belt. The rotation of the connecting ring 1 83 is transmitted to the connecting ring 2 84 via the belt, driving the connecting ring 2 84 to rotate at the same speed. The gear assembly 85 fixed to the outer wall of the connecting ring 2 84 rotates accordingly, and the gear assembly 85 then drives the connecting rod 86 to rotate in the opposite direction. The outer wall of the connecting rod 86 is rotatably connected to the inner wall of the fixed block 9. The fixed block 9 provides stable support and positioning for the connecting rod 86, ensuring that the connecting rod 86 maintains a precise axial position during rotation to avoid shaking or deviation. Mounting block 87, attached to the outer wall of connecting rod 86, rotates with the rod. As mounting block 87 rotates, the cable attached to it twists accordingly, achieving untwisting of the cable. This multi-stage transmission allows precise control of the untwisting speed and torque, meeting untwisting process requirements during cable production and ensuring that the quality of the produced cable meets standards.

[0031] When the connecting ring 1 83 rotates, it drives the fan blades 10 to rotate, thereby reducing the temperature of the double-headed motor 81.

[0032] Please see the attached Figure 3 and attached Figure 4 Gear assembly 85 includes a ring gear 851, the outer wall of which is fixedly connected to the outer wall of connecting ring 2 84. The tooth end of ring gear 851 is meshedly connected to a first gear 852, and the tooth end of first gear 852 is connected to a second gear 853. The outer wall of second gear 853 is fixedly connected to the outer wall of connecting rod 86. It should be noted that one end of first gear 852 is rotatably connected to fixed block 9 via a connecting shaft (not shown in the drawings).

[0033] Specifically, in the gear assembly 85, the ring gear 851 is fixed to the outer wall of the second connecting ring 84 and rotates with the second connecting ring 84. The ring gear 851 is meshed with the first gear 852. When the ring gear 851 rotates, it drives the first gear 852 to rotate. In turn, the first gear 852 drives the second gear 853 to rotate in the opposite direction. The second gear 853 is fixed to the outer wall of the connecting rod 86. Therefore, the rotation of the second gear 853 drives the connecting rod 86 to rotate in the opposite direction.

[0034] Please see the attached Figure 2 and attached Figure 6 The support assembly 11 includes a fixed plate 111, the lower surface of the fixed plate 111 is fixedly connected to the inner bottom wall of the shell 1, the outer wall of the fixed plate 111 is fixedly connected to the electric push rod 112, the output end of the electric push rod 112 is connected to the sliding plate 113, the upper surface of the sliding plate 113 is fixedly connected to the sliding plate 2 114, the outer wall of the sliding plate 2 114 is rotatably connected to the rotating wheel 115, and the outer wall of the rotating wheel 115 is fixedly connected to the limiting ring 116.

[0035] Specifically, before the equipment is put into operation, the operator will pre-set the operating parameters of the electric push rod 112 through the control center 6 based on the cable specifications, materials, and production process requirements. When the cable begins to untwist and pay out, the control center 6 sends instructions to the electric push rod 112 based on the cable status data monitored in real time. The electric push rod 112 performs telescopic movement according to the received instructions. Its output end is connected to the sliding plate 113. When the electric push rod 112 extends, it pushes the sliding plate 113 upward in the vertical direction; conversely, when the electric push rod 112 contracts, the sliding plate 113 descends.

[0036] A retaining ring 116, fixed to the outer wall of wheel 115, acts as a limiter. During the production process, the cable may experience lateral displacement due to various factors. Restricting ring 116 limits the cable's lateral movement, ensuring that the cable remains in the correct position for untwisting and payout operations, preventing the cable from deviating from its intended trajectory. This improves the accuracy and stability of cable production and ensures consistent product quality.

[0037] Please see the attached Figure 1 and attached Figure 7 The connecting component 12 includes a fixing rod 121, the outer wall of the fixing rod 121 is fixedly connected to the outer wall of the shell 1, the upper surface of the fixing rod 121 is fixedly connected to the fixing rod 2 122, the upper surface of the fixing rod 2 122 is rotatably connected to the rotating wheel 2 123, and a slide groove 124 is opened inside the shell 1, and the slide groove 124 cooperates with the rotating wheel 2 123 to realize smooth guidance of the cable.

[0038] Specifically, chute 124 provides a preset motion trajectory for the cable, working in conjunction with reel 2 123 to ensure precise cable guidance in all directions. Horizontally, chute 124 limits the cable's lateral displacement, preventing it from drifting left or right during movement. Vertically, reel 2 123 interacts with chute 124 to ensure the cable remains at the proper height for payout and untwisting operations. This effectively prevents cable entanglement and knotting during production, improving efficiency and quality while reducing scrap.

[0039] Please see the attached Figure 1 -Attached Figure 3 The control center 6 has a built-in tension sensor and a PLC controller. The PLC controller is electrically connected to the double-headed motor 81 and the electric push rod 112 for real-time monitoring and adjustment of the cable tension and back-twisting speed. An elastic buffer layer is provided between the flip plate 1 2 and the flip plate 2 4, and the material of the elastic buffer layer is rubber.

[0040] Specifically, the PLC controller, based on monitoring data, precisely controls the electric push rod 112, pushing the sliding plate 113 and sliding plate 2 114 up and down, driving the rotating wheel 115 to adjust its height, ensuring that the cable is always optimally supported. This automated adjustment process eliminates the need for frequent manual intervention, not only reducing operator workload but also significantly improving production efficiency, making the entire cable production process more efficient and streamlined. During operation of the payout frame, especially during the operation of the backtwist assembly, the equipment generates a certain degree of vibration. The rubber elastic buffer layer absorbs and disperses this vibration, reducing the transmission of vibration from the main body of the equipment to the cable.

[0041] Please see the attached Figure 2 A detachable filter is provided at the bottom of the collecting tank 7. The aperture of the filter is smaller than the cable diameter and is used to collect debris that falls off during the back-twisting process. A transparent observation window is provided on the outer wall of the flip plate 2. The observation window is made of high-temperature resistant tempered glass, which is convenient for real-time monitoring of the internal cable status.

[0042] Specifically, during the untwisting process, friction and other factors can cause the cable to produce debris, such as tiny particles from the insulation layer and wire fragments. The removable filter at the bottom of the collection tank 7 effectively collects this debris, preventing it from scattering around the equipment, keeping the production environment clean and tidy, reducing cleaning costs caused by debris contaminating the production site, and preventing debris from entering other production processes and affecting product quality. Operators can observe the status of the internal cables at any time without opening the flip plate 2. The observation window allows staff to promptly detect problems such as tangles, entanglements, and damaged outer sheaths, facilitating timely adjustments.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
