Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cable armor, and particularly relates to a cable steel belt armoring machine with a feeding mechanism. BACKGROUND

[0002] In a cable production process, steel belt armoring is an important process for enhancing the mechanical strength of a cable and improving the corrosion resistance, and a steel belt armoring machine is a key equipment for realizing the process.

[0003] When a traditional cable steel belt armoring machine replaces a steel belt roll, a heavy limiting disc needs to be manually completely disassembled from an installation shaft, and then reassembled and fixed after a new steel belt roll is replaced. Since the steel belt roll itself is heavy, and the limiting disc also has a certain weight, manual carrying is not only labor-intensive, but also easy to cause worker fatigue. Moreover, the replacement process takes a long time, frequent replacement operations increase the interruption time of armoring operation, and seriously affect the continuity and overall work efficiency of cable production.

[0004] In addition, if the limiting disc is not positioned accurately or locked firmly during manual installation, problems such as steel belt deviation and loosening may occur in the subsequent armoring process, which affects the cable armoring quality, and even causes equipment failure or safety hazards. Therefore, how to optimize the replacement mode of the steel belt roll, reduce the labor intensity of workers, shorten the replacement time, and at the same time ensure the stability and reliability of the replacement process, has become a problem to be solved for the existing cable steel belt armoring machine. SUMMARY

[0005] In order to make up for the shortcomings of the prior art, the application provides a cable steel belt armoring machine with a feeding mechanism. The application is mainly used to solve the problem that the existing cable steel belt armoring machine needs to manually disassemble a heavy limiting disc from an installation shaft, and then reassemble and fix it after replacing a new steel belt roll. Since the limiting disc is heavy and the replacement frequency is high, manual carrying is not only labor-intensive, but also takes a long time in the replacement process. The high labor intensity further increases the interruption time of armoring operation, and thus seriously affects the continuity and overall work efficiency of cable production.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: This invention provides a cable steel strip armoring machine with a feeding mechanism, including a frame, a winding rotating frame, a rotating support plate, a rotating bracket, an unwinding mechanism, and a driving mechanism; each of the two support plates of the frame is rotatably connected to one of the rotating support plates; the rotating bracket is fixedly connected between the two rotating support plates; the unwinding mechanism is symmetrically arranged on both sides of the rotating bracket; the other side of one of the rotating support plates is fixedly connected to the winding rotating frame; the winding rotating frame is used to wind the steel strip onto the cable; the other side of the other rotating support plate is connected to the driving mechanism; the driving mechanism is used to drive the rotating support plate and the rotating bracket to rotate. The unwinding mechanism includes a fixed disc, a mounting shaft, a limiting disc, a locking ring, a first hinge plate, a second hinge plate, and a fixed hinge plate. The fixed disc is fixedly connected to the rotating bracket. The mounting shaft is fixedly connected to the central axis of the fixed disc. During operation, the limiting disc is sleeved on the mounting shaft. The locking ring is rotatably connected to the outer side of the limiting disc. The locking ring is connected to the mounting shaft via a fine-pitch thread. A rotating handle is provided on the locking ring. The limiting disc is sequentially hinged to the first hinge plate, the second hinge plate, and the fixed hinge plate via hinges. The non-hinged end of the fixed hinge plate is fixedly connected to the rotating bracket.

[0007] During operation, the steel strip roll is placed on the mounting shaft, with one side of the roll in contact with the fixed disc. Then, the limiting disc is placed on the mounting shaft, contacting the other side of the roll. The rotating handle on the locking ring is turned, utilizing the fine-pitch thread between the locking ring and the mounting shaft to move the limiting disc towards the steel strip roll until it is clamped and fixed between the fixed disc and the limiting disc. At this time, the linkage structure composed of the first hinge plate, the second hinge plate, and the fixed hinge plate rotates adaptively under the pressure of the limiting disc, providing auxiliary guidance for the movement of the limiting disc and ensuring the steel strip roll is securely installed. The drive mechanism starts, driving the rotating support disc connected to it to rotate. This, in turn, drives the rotating support disc on the other side and the unwinding mechanism fixed to the rotating support to rotate synchronously. The steel strip roll on the unwinding mechanism rotates with the rotating support, while the free end of the steel strip is pulled to the winding rotating frame. Under the rotation of the winding rotating frame, the steel strip gradually winds onto the cable passing through the center of the winding rotating frame, completing the steel strip armoring operation of the cable. After the steel strip roll on the fixed plate is used up, the fixed plate is rotated to a vertical angle and then stopped. The rotating handle is then rotated in the opposite direction to remove the limiting plate from the mounting shaft. The removed limiting plate is laterally supported by the first hinge plate, the second hinge plate, and the fixed hinge plate. This allows the steel strip roll to be replaced without having to completely remove the limiting plate, thus saving labor intensity for workers. At the same time, this operation, which does not require manual handling of the limiting plate, greatly shortens the time for replacing the steel strip roll, thereby improving the efficiency of cable armoring.

[0008] Preferably, the unwinding mechanism further includes an automatic locking unit; the automatic locking unit includes a lever handle, a swing groove block, a piston rod, a first spring, a drive cylinder, a hydraulic pipe, a telescopic cylinder, and a tensioning rod; a telescopic cylinder is provided at the hinge connecting the limiting plate, the first hinge plate, the second hinge plate, and the fixed hinge plate; the telescopic cylinder hydraulically drives the tensioning rod to abut against the hinge surface of adjacent parts; all the inlets of the telescopic cylinders are connected to the outlet of the drive cylinder through the hydraulic pipe; the drive cylinder is fixedly connected to the stepped surface on the locking ring; the piston rod is slidably connected inside the drive cylinder; the first spring is provided on the side of the piston at the end of the piston rod where there is no hydraulic oil; the sliding shaft provided at the extended end of the piston rod slides in the waist-shaped groove on the swing groove block; one end of the swing groove block is hinged to the locking ring; one side of the swing groove block is fixedly connected to one end of the lever handle.

[0009] During operation, after the limiting plate is removed from the mounting shaft, since the hinges between the first hinge plate, the second hinge plate, and the fixed hinge plate lack a binding force in the direction of rotation, the limiting plate cannot be completely confined to the side of the fixed plate. Consequently, the limiting plate may move and obstruct the replacement of the steel strip roll. Therefore, in the free state, this solution utilizes the elastic force of the first spring to squeeze the hydraulic oil in the drive cylinder, allowing the hydraulic oil to enter each telescopic cylinder through the hydraulic pipe. This pushes the tensioning rod to extend and abut against the hinge surface of the adjacent hinge. The friction between the tensioning rod and the hinge surface achieves automatic locking between the first hinge plate, the second hinge plate, and the fixed hinge plate, preventing the limiting plate from rotating unexpectedly. When a new steel strip coil needs to be installed, the lever is turned, causing the swing block to rotate around its hinge point with the locking ring. The oblong groove on the swing block drives the sliding shaft at the end of the piston rod to move, causing the piston rod to compress the first spring and slide into the drive cylinder. This draws the hydraulic oil in the drive cylinder back through the hydraulic pipe, reducing the hydraulic oil in the telescopic cylinder. The clamping rod retracts under the action of its own return spring, releasing the locking of the first hinge plate, the second hinge plate, and the fixed hinge plate. At this time, the limit plate can be freely rotated to replace the steel strip coil. After replacement, the lever is released, the first spring returns to its original position, pushing the piston rod to move. The hydraulic oil re-enters the telescopic cylinder, and the clamping rod extends again to achieve automatic locking, ensuring that the limit plate remains stable when not in the replacement state.

[0010] Preferably, an electric telescopic rod is provided between the fixed plate and the limiting plate; the cylinder of the electric telescopic rod is fixedly connected to the rotating bracket; and the extended end of the electric telescopic rod is fixedly connected to the rotating seat of the damping wheel.

[0011] During operation, the electric telescopic rod extends and retracts adaptively according to the diameter of the steel strip roll, causing the damping wheel to contact the outer circumference of the steel strip roll. The friction between the damping wheel and the steel strip roll regulates the unwinding speed, preventing the steel strip from becoming loose or stacked due to inertia during unwinding. This ensures the steel strip is delivered to the winding frame with stable tension, improving the uniformity and tightness of the steel strip winding on the cable. As the diameter of the steel strip roll gradually decreases during unwinding, the electric telescopic rod continues to extend, keeping the damping wheel in constant contact with the outer circumference of the steel strip roll, maintaining a stable damping effect until the steel strip roll is completely unwound.

[0012] Preferably, the damping wheel is rotatably connected to the support shaft; an elastic rubber sleeve is provided on the mounting surface where the support shaft connects to the rotating seat; and a wear-resistant rubber layer is fixedly connected to the side surface of the rotating seat near the damping wheel.

[0013] During operation, the damping wheel is mounted on the rotating seat via a support shaft. The elastic rubber sleeve between the support shaft and the rotating seat has a certain elastic deformation capacity. When the outer circumference of the steel strip coil is uneven or has diameter fluctuations, the elastic rubber sleeve can cause the damping wheel to adaptively follow the changes in the outer circumference of the steel strip coil through its own elastic deformation, making slight oscillations. This ensures that the damping wheel always maintains good contact with the outer circumference of the steel strip coil, avoiding sudden changes in damping force due to poor contact, which would affect the stability of the steel strip unwinding. At the same time, by adjusting the pressure applied to the damping wheel by the electric push rod, the compression of the elastic rubber sleeve can be changed, thereby changing the magnitude of the friction between the wear-resistant rubber layer and the damping wheel. This allows for adjustment of the friction between the damping wheel and the steel strip coil, enabling precise control of the unwinding speed of steel strips of different materials and thicknesses.

[0014] Preferably, a torque sensor is provided between the damping wheel and the support shaft; the drive mechanism includes a rotary drive unit and an electromagnetic brake unit.

[0015] During operation, when the torque sensor detects that the damping wheel is no longer applying torque, it means the steel strip roll on the fixed disc has run out. Upon receiving the electrical signal from the torque sensor, the controller immediately activates the electromagnetic brake unit, applying brakes to the rotating support disc. This stops the rotating bracket and the unwinding mechanism, maintaining their current position so that workers can promptly replace the steel strip roll. Once a new steel strip roll has been replaced and re-clamped, the worker presses the reset button. The controller then releases the electromagnetic brake unit, restarting the drive mechanism and resuming the rotation of the rotating bracket and unwinding mechanism to continue the steel strip armoring operation for the cable. Real-time monitoring of the damping wheel torque by the torque sensor automatically determines whether the steel strip roll is exhausted, eliminating the need for constant manual observation. This automatic shutdown when the steel strip roll is depleted prevents idling, further improving the automation and reliability of the equipment. It also facilitates rapid replacement of the steel strip roll.

[0016] Preferably, at least two sets of telescopic guide rods are provided between the rotating seat and the rotating bracket; the two ends of the telescopic guide rods are respectively fixedly connected to the rotating seat and the rotating bracket.

[0017] The telescopic guide rod consists of an inner rod and an outer cylinder. The inner rod slides inside the outer cylinder, and the end of the outer cylinder is fixedly connected to a rotating bracket. The end of the inner rod is fixedly connected to a rotating seat. During operation, when the electric telescopic rod drives the rotating seat and damping wheel to extend and retract, the inner rod of the telescopic guide rod slides synchronously within the outer cylinder, providing precise guidance for the movement direction of the rotating seat. This prevents the rotating seat from shifting or wobbling during movement and ensures that the damping wheel maintains accurate contact with the outer circumference of the steel strip coil, guaranteeing the stability of the damping adjustment effect. Simultaneously, the telescopic guide rod also shares the radial force borne by the electric telescopic rod, preventing damage due to long-term uneven loading and extending its service life. The multiple sets of telescopic guide rods further enhance the stability of the guidance and the overall rigidity of the structure, making the movement of the rotating seat smoother and more reliable.

[0018] Preferably, the mounting shaft is provided with sliding grooves at uniform intervals along the circumferential direction; the groove depth of the sliding groove is greater than the tooth height of the fine thread on the mounting shaft; the locking ring is provided with clearance grooves at uniform intervals along the circumferential direction in the thread, and the thread width retained on the locking ring is less than the width of the sliding groove on the mounting shaft.

[0019] During operation, the sliding groove on the mounting shaft and the clearance groove on the locking ring engage with each other. When the limiting disc is fitted onto or removed from the mounting shaft, the locking ring can be rotated to align the clearance groove on the locking ring with the sliding groove on the mounting shaft. At this point, the locking ring can move quickly along the axial direction of the mounting shaft, allowing for rapid loading and unloading of the limiting disc without rotating the locking ring, further shortening the operation time for changing steel strip coils. Once the limiting disc has moved to the designated position, rotating the locking ring engages the threaded portion on the locking ring with the fine-pitch thread on the mounting shaft. Rotating the handle then drives the locking ring to clamp and fix the limiting disc. This structural design ensures locking reliability while improving the ease of loading and unloading the limiting disc, significantly improving operational efficiency, especially in scenarios requiring frequent steel strip coil changes.

[0020] Preferably, the winding rotating frame includes a mounting turntable, a first support rod, a second support rod, a fixed plate, a guide plate, a first reversing guide wheel, an auxiliary support plate, a second reversing guide wheel, and a third reversing guide wheel; the mounting turntable is fixedly connected to one side of the rotating support plate; the fixed plate is fixedly connected to the mounting turntable by the first and second support rods arranged laterally; the guide plate is fixedly connected to the middle of the two first support rods; the auxiliary support plate is fixedly connected to the second support rod; the second reversing guide wheel is arranged at one end of the auxiliary support plate near its inner side; the auxiliary support plate is located near its inner side... A third reversing guide wheel is provided at one of the outer ends; the second reversing guide wheel is hinged to the auxiliary support plate via a swing frame; a second spring is provided below the swing frame, offset from the hinge axis; the lower end of the second spring is fixedly connected to the auxiliary support plate via a support block; a first reversing guide wheel is provided on the mounting turntable at a position corresponding to the second reversing guide wheel laterally; the first reversing guide wheel is rotatably connected to the mounting turntable via a mounting base; a fourth reversing guide wheel with two wheels arranged side by side is provided on the other side of the rotating support plate at a position corresponding to the first reversing guide wheel; the fourth reversing guide wheel is positioned laterally corresponding to the position of the fixed plate.

[0021] During operation, the steel strip is drawn from the unwinding mechanism and sequentially passes around the fourth, first, second, and third guide rollers before being guided to the center of the winding rotating frame. The fourth guide roller provides initial guidance and transition, while the first guide roller further adjusts the steel strip's direction to ensure smooth transmission to the second guide roller. The second guide roller is hinged to the auxiliary support plate via a swing frame and maintains tension on the steel strip under the action of the second spring. When tension fluctuations occur during unwinding, the second guide roller uses the adaptive swing of the swing frame and the elastic deformation of the second spring to buffer and adjust, ensuring the steel strip remains at the appropriate tension and preventing excessive tension leading to stretching or insufficient tension causing loosening and wrinkling. The third guide roller guides the steel strip to the central axis of the winding rotating frame, precisely aligning it with the cable passing through the center, so that the steel strip can be evenly and tightly wound onto the cable surface. As the installation turntable rotates together with the rotating support plate, the steel strip, guided by multiple guide wheels, continuously winds around the cable with stable tension and angle, ensuring the forming quality of the armor layer.

[0022] Preferably, a pressure sensor is provided between the second spring and the support block.

[0023] During operation, when the pressure sensor reading is lower than the set value, the controller extends the electric telescopic rod, increasing the pressure on the damping wheel. This increases the friction between the damping wheel and the steel strip coil, increasing the tension of the steel strip. Consequently, the compression of the second spring increases, and the pressure detected by the pressure sensor returns to the set range. Conversely, when the pressure sensor reading is higher than the set value, the controller shortens the electric telescopic rod, reducing the pressure on the damping wheel and decreasing the friction between the damping wheel and the steel strip coil. This reduces the tension of the steel strip, decreases the compression of the second spring, and the pressure detected by the pressure sensor returns to the set range. Real-time monitoring of the second spring pressure by the pressure sensor provides dynamic feedback on the steel strip tension. The controller automatically adjusts the extension of the electric telescopic rod based on the feedback signal, achieving closed-loop control of the steel strip tension. This ensures that the steel strip maintains a constant tension throughout the armoring process, effectively preventing problems such as uneven armor layer tightness, steel strip wrinkles, or breakage caused by unstable tension, further improving the product quality of cable armor.

[0024] Preferably, the third guide wheel and the auxiliary support plate are rotatably connected by a vertical pivot; the relative rotation between the third guide wheel and the auxiliary support plate is restricted by an elastic band.

[0025] During operation, the third guide wheel can rotate horizontally relative to the auxiliary support plate via a vertical pivot. When the steel strip experiences lateral tension due to slight changes in cable diameter or deviations in winding angle during the winding process, the third guide wheel can adaptively rotate around the vertical pivot at a certain angle. This allows the steel strip to enter the winding position at a more suitable angle, reducing frictional resistance and localized stress concentration between the steel strip and the wheel rim, and preventing wear or curling of the steel strip edges. The elastic band limits the rotation angle of the third guide wheel. When the lateral tension disappears, the elastic band pulls the third guide wheel back to its initial guide position, ensuring the guiding accuracy of subsequent steel strips. This rotatable structure with a reset function further improves the adaptability of the third guide wheel to changes in the steel strip's direction, ensuring the smoothness and stability of the steel strip winding process.

[0026] The beneficial effects of this invention are as follows: 1. In this invention, the linkage structure composed of the first hinge plate, the second hinge plate, and the fixed hinge plate undergoes adaptive rotation under the squeezing action of the limiting plate, providing auxiliary guidance for the movement of the limiting plate and ensuring the stable installation of the steel strip roll. After the steel strip roll on the fixed plate is used up, the fixed plate is controlled to rotate to a vertical angle and then stopped. The rotating handle is then turned in the opposite direction to remove the limiting plate from the mounting shaft. The removed limiting plate is laterally supported by the first hinge plate, the second hinge plate, and the fixed hinge plate, thus allowing for steel strip roll replacement without completely removing the limiting plate. This saves labor intensity and significantly reduces the time required to replace the steel strip roll, thereby improving the efficiency of cable armoring.

[0027] 2. In the free state, the first spring's elastic force compresses the hydraulic oil in the drive cylinder, causing the hydraulic oil to enter each telescopic cylinder through the hydraulic pipe. This pushes the tightening rod to extend and abut against the hinge surface of adjacent hinges. The friction between the tightening rod and the hinge surface achieves automatic locking between the first hinge plate, the second hinge plate, and the fixed hinge plate, preventing unexpected rotation of the limit plate. When a new steel strip coil needs to be installed, the lever is turned, causing the swing block to rotate around its hinge point with the locking ring. The waist-shaped groove on the swing block drives the sliding shaft at the end of the piston rod to move, causing the piston rod to compress the first spring and slide into the drive cylinder. This draws the hydraulic oil in the drive cylinder back through the hydraulic pipe, reducing the amount of hydraulic oil in the telescopic cylinder. The tightening rod retracts under the action of its own return spring, releasing the locking of the first hinge plate, the second hinge plate, and the fixed hinge plate. At this time, the limit plate can be freely rotated for steel strip coil replacement. After replacement, release the lever, the first spring returns to its original position and pushes the piston rod to move. Hydraulic oil re-enters the telescopic cylinder, and the clamping rod extends again to achieve automatic locking, ensuring that the limit plate remains stable when not being replaced.

[0028] 3. In this invention, the electric telescopic rod adapts to the diameter of the steel strip roll, causing the damping wheel to contact the outer circumference of the steel strip roll. The friction between the damping wheel and the steel strip roll regulates the unwinding speed, preventing the steel strip from becoming loose or stacked due to inertia during unwinding. This ensures the steel strip is delivered to the winding frame with stable tension, improving the uniformity and tightness of the steel strip winding on the cable. As the diameter of the steel strip roll gradually decreases during unwinding, the electric telescopic rod continues to extend, keeping the damping wheel in constant contact with the outer circumference of the steel strip roll, maintaining a stable damping effect until the steel strip roll is completely unwound.

[0029] 4. In this invention, the damping wheel is mounted on the rotating seat via a support shaft. The elastic rubber sleeve between the support shaft and the rotating seat has a certain elastic deformation capability. When the outer circumference of the steel strip coil is uneven or has diameter fluctuations, the elastic rubber sleeve can cause the damping wheel to adaptively follow the changes in the outer circumference of the steel strip coil through its own elastic deformation, ensuring that the damping wheel always maintains good contact with the outer circumference of the steel strip coil, avoiding sudden changes in damping force due to poor contact, which would affect the stability of the steel strip unwinding. At the same time, by adjusting the pressure applied to the damping wheel by the electric push rod, the compression of the elastic rubber sleeve can be changed, thereby changing the magnitude of the friction between the wear-resistant rubber layer and the damping wheel, thus achieving adjustment of the friction between the damping wheel and the steel strip coil, and realizing precise control of the unwinding speed of steel strips of different materials and thicknesses.

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 3 As shown, a cable steel strip armoring machine with a feeding mechanism includes a frame 1, a winding rotating frame 2, a rotating support plate 3, a rotating bracket 4, an unwinding mechanism 5, and a drive mechanism 6. One of the rotating support plates 3 is rotatably connected to each of the two support plates of the frame 1. The rotating bracket 4 is fixedly connected between the two rotating support plates 3. The unwinding mechanism 5 is symmetrically arranged on both sides of the rotating bracket 4. The other side of one of the rotating support plates 3 is fixedly connected to the winding rotating frame 2. The winding rotating frame 2 is used to wind the steel strip onto the cable. The other side of the other rotating support plate 3 is connected to the drive mechanism 6. The drive mechanism 6 is used to drive the rotating support plate 3 and the rotating bracket 4 to rotate. The unwinding mechanism 5 includes a fixed disk 51, a mounting shaft 52, a limiting disk 53, a locking ring 54, a first hinge plate 55, a second hinge plate 56, and a fixed hinge plate 57. The fixed disk 51 is fixedly connected to the rotating bracket 4. The mounting shaft 52 is fixedly connected to the central axis of the fixed disk 51. During operation, the limiting disk 53 is sleeved on the mounting shaft 52. The locking ring 54 is rotatably connected to the outer side of the limiting disk 53. The locking ring 54 is connected to the mounting shaft 52 by a fine thread. A rotating handle is provided on the locking ring 54. The limiting disk 53 is sequentially hinged to the first hinge plate 55, the second hinge plate 56, and the fixed hinge plate 57 through a hinge connection. The non-hinged end of the fixed hinge plate 57 is fixedly connected to the rotating bracket 4.

[0034] During operation, the steel strip roll is placed on the mounting shaft 52, with one side of the roll in contact with the fixing plate 51. Then, the limiting plate 53 is placed on the mounting shaft 52, contacting the other side of the steel strip roll. The rotating handle on the locking ring 54 is rotated, utilizing the fine-pitch thread between the locking ring 54 and the mounting shaft 52 to move the limiting plate 53 towards the steel strip roll until it is clamped and fixed between the fixing plate 51 and the limiting plate 53. At this time, the linkage structure composed of the first hinge plate 55, the second hinge plate 56, and the fixed hinge plate 57 undergoes adaptive rotation under the pressure of the limiting plate 53, providing auxiliary guidance for the movement of the limiting plate 53 and ensuring the steel strip roll is securely installed. The drive mechanism 6 is started, which drives the rotating support plate 3 connected to it to rotate. Then, through the rotating bracket 4, the rotating support plate 3 on the other side and the unwinding mechanism 5 fixed on the rotating bracket 4 are rotated synchronously. The steel strip roll on the unwinding mechanism 5 rotates together with the rotating bracket 4. At the same time, the free end of the steel strip is pulled to the winding rotating frame 2. Under the rotation of the winding rotating frame 2, the steel strip is gradually wound around the cable passing through the center of the winding rotating frame 2, completing the steel strip armoring operation of the cable. After the steel strip roll on the fixed plate 51 is used up, the fixed plate 51 is rotated to a vertical angle and stopped. The rotating handle is then rotated in the opposite direction to remove the limiting plate 53 from the mounting shaft 52. The removed limiting plate 53 is laterally supported by the first hinge plate 55, the second hinge plate 56, and the fixed hinge plate 57. This allows the steel strip roll to be replaced on the fixed plate 51 without having to completely remove the limiting plate 53, thus saving labor intensity for workers. At the same time, this operation, which does not require manual movement of the limiting plate 53, greatly shortens the time for replacing the steel strip roll, thereby improving the efficiency of cable armoring.

[0035] like Figure 3 , Figure 5 , Figure 8 and Figure 9As shown, the unwinding mechanism 5 further includes an automatic locking unit 58; the automatic locking unit 58 includes a lever handle 581, a swing groove block 582, a piston rod 583, a first spring 584, a drive cylinder 585, a hydraulic pipe, a telescopic cylinder 586, and a tensioning rod 587; a telescopic cylinder 586 is provided at the hinge connecting the limiting plate 53, the first hinge plate 55, the second hinge plate 56, and the fixed hinge plate 57; the telescopic cylinder 586 hydraulically drives the tensioning rod 587 to abut against the hinge surface of adjacent parts; all the inlets of the telescopic cylinders 586 are... The hydraulic pipe is connected to the outlet of the drive cylinder 585; the drive cylinder 585 is fixedly connected to the stepped surface of the locking ring 54; the piston rod 583 is slidably connected inside the drive cylinder 585; the first spring 584 is provided on the piston side without hydraulic oil at the end of the piston rod 583; the sliding shaft provided at the protruding end of the piston rod 583 slides in the waist-shaped groove on the swing block 582; one end of the swing block 582 is hinged to the locking ring 54; one side of the swing block 582 is fixedly connected to one end of the lever handle 581.

[0036] During operation, after the limiting plate 53 is removed from the mounting shaft 52, since the hinges between the first hinge plate 55, the second hinge plate 56, and the fixed hinge plate 57 lack a binding force in the direction of rotation, the limiting plate 53 cannot be completely restricted to one side of the fixed plate 51. Consequently, the limiting plate 53 may move and obstruct the replacement of the steel strip roll. Therefore, in this solution, in the free state, the elastic force of the first spring 584 is used to squeeze the hydraulic oil in the drive cylinder 585, so that the hydraulic oil enters each telescopic cylinder 586 through the hydraulic pipe, pushing the top clamping rod 587 to extend and abut against the hinge surface of the adjacent hinge. The friction between the top clamping rod 587 and the hinge surface achieves automatic locking between the first hinge plate 55, the second hinge plate 56, and the fixed hinge plate 57, preventing the limiting plate 53 from rotating unexpectedly. When a new steel strip coil needs to be installed, the lever 581 is turned, causing the swing block 582 to rotate around its hinge point with the locking ring 54. The waist-shaped groove on the swing block 582 drives the sliding shaft at the end of the piston rod 583 to move, causing the piston rod 583 to compress the first spring 584 and slide into the drive cylinder 585. This draws the hydraulic oil in the drive cylinder 585 back through the hydraulic pipe, reducing the hydraulic oil in the telescopic cylinder 586. The clamping rod 587 retracts under the action of its own return spring, releasing the locking of the first hinge plate 55, the second hinge plate 56, and the fixed hinge plate 57. At this time, the limit plate 53 can be freely rotated to perform the steel strip coil replacement operation. After the replacement is completed, the lever 581 is released, the first spring 584 returns to its original position, pushing the piston rod 583 to move. The hydraulic oil re-enters the telescopic cylinder 586, and the clamping rod 587 extends again to achieve automatic locking, ensuring that the limit plate 53 remains stable when not in the replacement state.

[0037] like Figure 3 ,Figure 4 and Figure 6 As shown, an electric telescopic rod 59 is provided between the fixed plate 51 and the limiting plate 53; the cylinder of the electric telescopic rod 59 is fixedly connected to the rotating bracket 4; the extended end of the electric telescopic rod 59 is fixedly connected to the rotating seat 592 of the damping wheel 591.

[0038] During operation, the electric telescopic rod 59 extends and retracts adaptively according to the diameter of the steel strip roll, causing the damping wheel 591 to contact the outer circumference of the steel strip roll. The friction between the damping wheel 591 and the steel strip roll regulates the unwinding speed, preventing the steel strip from becoming loose or stacked due to inertia during unwinding. This ensures the steel strip is delivered to the winding rotating frame 2 with stable tension, improving the uniformity and tightness of the steel strip winding on the cable. As the diameter of the steel strip roll gradually decreases during unwinding, the electric telescopic rod 59 continues to extend, keeping the damping wheel 591 in constant contact with the outer circumference of the steel strip roll, maintaining a stable damping effect until the steel strip roll is completely unwound.

[0039] like Figure 7 As shown, the damping wheel 591 is rotatably connected to the support shaft 593; an elastic rubber sleeve 594 is provided on the mounting surface where the support shaft 593 is connected to the rotating seat 592; and a wear-resistant rubber layer 595 is fixedly connected to the side surface of the rotating seat 592 near the damping wheel 591.

[0040] During operation, the damping wheel 591 is mounted on the rotating seat 592 via the support shaft 593. The elastic rubber sleeve 594 between the support shaft 593 and the rotating seat 592 has a certain elastic deformation capability. When the outer circumference of the steel strip coil is uneven or there are diameter fluctuations, the elastic rubber sleeve 594 can cause the damping wheel 591 to adaptively follow the changes in the outer circumference of the steel strip coil through its own elastic deformation, ensuring that the damping wheel 591 always maintains good contact with the outer circumference of the steel strip coil, avoiding sudden changes in damping force due to poor contact, which would affect the stability of the steel strip unwinding. At the same time, by adjusting the pressure applied to the damping wheel 591 by the electric push rod, the compression of the elastic rubber sleeve 594 can be changed, thereby changing the magnitude of the friction between the wear-resistant rubber layer 595 and the damping wheel 591. This allows for adjustment of the friction between the damping wheel 591 and the steel strip coil, achieving precise control of the unwinding speed of steel strips of different materials and thicknesses. The wear-resistant rubber layer 595 on the rotating seat 592 can reduce the direct friction between the support shaft 593 and the rotating seat 592 when the damping wheel 591 swings, thus extending the service life of the rotating seat 592. It can also play a certain buffering role and reduce the noise generated during the swing of the damping wheel 591.

[0041] like Figure 1 and Figure 2As shown, a torque sensor is provided between the damping wheel 591 and the support shaft 593; the drive mechanism 6 includes a rotary drive unit 61 and an electromagnetic brake unit 62.

[0042] During operation, when the torque sensor detects that the damping wheel 591 is no longer applying torque, it means the steel strip roll on the fixed disc 51 has run out of power. Upon receiving the electrical signal from the torque sensor, the controller immediately activates the electromagnetic brake unit 62, applying brakes to the rotating support disc 3. This stops the rotating bracket 4 and the unwinding mechanism 5, maintaining their current position so that workers can promptly replace the steel strip roll. Once a new steel strip roll has been replaced and re-clamped, the worker operates the reset button. The controller then releases the brakes from the electromagnetic brake unit 62, restarting the drive mechanism 6 and resuming the rotation of the rotating bracket 4 and the unwinding mechanism 5, continuing the steel strip armoring operation for the cable. Real-time monitoring of the torque of the damping wheel 591 by the torque sensor automatically determines whether the steel strip roll is exhausted, eliminating the need for constant manual observation. This achieves automatic shutdown when the steel strip roll is depleted, preventing idling and further improving the automation and reliability of the equipment. It also facilitates rapid replacement of the steel strip roll.

[0043] like Figure 3 , Figure 4 and Figure 6 As shown, at least two sets of telescopic guide rods 596 are provided between the rotating seat 592 and the rotating bracket 4; the two ends of the telescopic guide rods 596 are respectively fixedly connected to the rotating seat 592 and the rotating bracket 4.

[0044] The telescopic guide rod 596 consists of an inner rod and an outer cylinder. The inner rod is slidably fitted inside the outer cylinder, and the end of the outer cylinder is fixedly connected to the rotating bracket 4. The end of the inner rod is fixedly connected to the rotating seat 592. During operation, when the electric telescopic rod 59 drives the rotating seat 592 and the damping wheel 591 to telescopically move, the inner rod of the telescopic guide rod 596 slides synchronously inside the outer cylinder, providing precise guidance for the movement direction of the rotating seat 592. This prevents the rotating seat 592 from shifting or wobbling during movement and ensures that the damping wheel 591 maintains accurate contact with the outer circumference of the steel strip coil, guaranteeing the stability of the damping adjustment effect. Simultaneously, the telescopic guide rod 596 also shares the radial force borne by the electric telescopic rod 59, preventing damage to the electric telescopic rod 59 due to long-term uneven loading and extending its service life. The multiple sets of telescopic guide rods 596 further enhance the stability of the guidance and the overall rigidity of the structure, making the movement of the rotating seat 592 more stable and reliable.

[0045] like Figure 4 and Figure 5As shown, the mounting shaft 52 is provided with sliding grooves 521 evenly spaced along the circumferential direction; the groove depth of the sliding groove 521 is greater than the tooth height of the fine thread on the mounting shaft 52; the locking ring 54 is provided with clearance grooves evenly spaced along the circumferential direction in the thread, and the thread width retained on the locking ring 54 is less than the width of the sliding groove 521 on the mounting shaft 52.

[0046] During operation, the sliding groove 521 on the mounting shaft 52 and the clearance groove on the locking ring 54 cooperate with each other. When the limiting disc 53 is fitted onto or removed from the mounting shaft 52, the locking ring 54 can be rotated to align the clearance groove on the locking ring 54 with the sliding groove 521 on the mounting shaft 52. At this time, the locking ring 54 can move quickly along the axial direction of the mounting shaft 52, and the limiting disc 53 can be quickly loaded and unloaded without rotating the locking ring 54, further shortening the operation time for changing steel strip coils. After the limiting disc 53 moves to the designated position, the locking ring 54 is rotated to engage the threaded part on the locking ring 54 with the fine thread on the mounting shaft 52. Then, by rotating the handle to drive the locking ring 54 to rotate, the limiting disc 53 can be clamped and fixed. This structural design ensures the reliability of locking while improving the convenience of loading and unloading the limiting disc 53, which can significantly improve the operating efficiency, especially in operation scenarios where steel strip coils need to be changed frequently.

[0047] like Figures 10 to 13 As shown, the winding rotating frame 2 includes a mounting turntable 21, a first support rod 22, a second support rod 23, a fixing plate 24, a guide plate 25, a first reversing guide wheel 26, an auxiliary support plate 27, a second reversing guide wheel 28, and a third reversing guide wheel 29. The mounting turntable 21 is fixedly connected to one side of the rotating support plate 3. The fixing plate 24 is fixedly connected to the mounting turntable 21 by the first support rod 22 and the second support rod 23 arranged laterally. The guide plate 25 is fixedly connected to the middle of the two first support rods 22. The auxiliary support plate 27 is fixedly connected to the second support rod 23. The second reversing guide wheel 28 is arranged at one end of the auxiliary support plate 27 near the inner side. A third reversing guide wheel 29 is provided at one end of the outer side; the second reversing guide wheel 28 is hinged to the auxiliary support plate 27 via a swing frame 281; a second spring 282 is provided below the swing frame 281, offset from the hinge axis; the lower end of the second spring 282 is fixedly connected to the auxiliary support plate 27 via a support block 283; a first reversing guide wheel 26 is provided on the mounting turntable 21 at a position corresponding to the second reversing guide wheel 28; the first reversing guide wheel 26 is rotatably connected to the mounting turntable 21 via a mounting base; a fourth reversing guide wheel 20 with two wheels arranged side by side is provided on the other side of the rotating support plate 3 at a position corresponding to the first reversing guide wheel 26; the fourth reversing guide wheel 20 is positioned laterally corresponding to the position of the fixed plate 51.

[0048] During operation, after the steel strip is drawn out from the unwinding mechanism 5, it passes in sequence around the fourth guide wheel 20, the first guide wheel 26, the second guide wheel 28 and the third guide wheel 29, and is finally guided to the center position of the winding rotating frame 2. The fourth guide wheel 20 serves as an initial guide and transition wheel, while the first guide wheel 26 further adjusts the direction of the steel strip to ensure smooth transmission to the second guide wheel 28. The second guide wheel 28 is hinged to the auxiliary support plate 27 via the swing frame 281 and maintains tension on the steel strip under the action of the second spring 282. When tension fluctuations occur during unwinding, the second guide wheel 28 can buffer and adjust through the adaptive swing of the swing frame 281 and the elastic deformation of the second spring 282, ensuring that the steel strip is always in a suitable tension state, avoiding excessive tension leading to stretching and deformation or insufficient tension leading to loosening and wrinkling. The third guide wheel 29 guides the steel strip to the central axis of the winding rotating frame 2, precisely aligning it with the cable passing through the center, so that the steel strip can be evenly and tightly wound on the cable surface. As the installation turntable 21 rotates together with the rotating support plate 3, the steel strip, under the coordinated guidance of multiple guide wheels, continuously winds onto the cable with stable tension and angle, ensuring the forming quality of the armor layer.

[0049] like Figure 12 and Figure 13 As shown, a pressure sensor 284 is provided between the second spring 282 and the support block 283.

[0050] During operation, when the pressure value of pressure sensor 284 is lower than the set value, the controller controls the electric telescopic rod 59 to extend, increasing the pressure on damping wheel 591, thereby increasing the friction between damping wheel 591 and steel strip coil, increasing the tension of steel strip, and consequently increasing the compression of second spring 282. The pressure value detected by pressure sensor 284 then rises back to the set range. When the pressure value of pressure sensor 284 is higher than the set value, the controller controls the electric telescopic rod 59 to shorten, reducing the pressure on damping wheel 591, decreasing the friction between damping wheel 591 and steel strip coil, reducing the tension of steel strip, decreasing the compression of second spring 282, and causing the pressure value detected by pressure sensor 284 to fall back to the set range. By monitoring the pressure of the second spring 282 in real time through the pressure sensor 284, the tension of the steel strip can be dynamically fed back. The controller automatically adjusts the extension and retraction of the electric telescopic rod 59 according to the feedback signal, realizing closed-loop control of the steel strip tension. This ensures that the steel strip maintains a constant tension during the armoring process, effectively avoiding problems such as uneven tightness of the armor layer, steel strip wrinkles or breakage caused by unstable tension, and further improving the product quality of cable armor.

[0051] like Figure 12 and Figure 13As shown, the third guide wheel 29 and the auxiliary support plate 27 are rotatably connected by a vertical shaft; the relative rotation between the third guide wheel 29 and the auxiliary support plate 27 is restricted by an elastic band 291.

[0052] During operation, the third guide wheel 29 can rotate horizontally relative to the auxiliary support plate 27 via a vertical pivot. When the steel strip experiences lateral tension on the third guide wheel 29 due to slight changes in cable diameter or deviations in winding angle during the winding process, the third guide wheel 29 can adaptively rotate around the vertical pivot at a certain angle. This allows the steel strip to enter the winding position at a more suitable angle, reducing frictional resistance and local stress concentration between the steel strip and the rim of the third guide wheel 29, and preventing wear or curling of the steel strip edges. The elastic band 291 limits the rotation angle of the third guide wheel 29. When the lateral tension disappears, the elastic band 291 pulls the third guide wheel 29 to automatically return to its initial guide position, ensuring the guiding accuracy of the subsequent steel strip. This rotatable structure with a reset function further improves the adaptability of the third guide wheel 29 to changes in the steel strip direction, ensuring the smoothness and stability of the steel strip winding process.
