Description

Technical Field

[0001] This application relates to the technical field of steel tape armoring machines, specifically a steel tape armoring machine for producing rubber-sheathed flexible cables. Background Technology

[0002] Steel tape armoring machines are essential equipment for wire and cable factories to produce power cables, plastic cables, and control cables. Rubber-sheathed cables are a type of flexible and movable cable with multiple strands of fine copper wire as conductors, and rubber insulation and rubber sheath. In the production process of rubber-sheathed flexible cables, armoring is required.

[0003] Currently, cable armoring requires wrapping steel coils around the outer wall of the cable during winding. However, when the cable is being wound, the working line is quite long, and the cable is prone to shaking during operation. If the tension is insufficient, the shaking will intensify, which will lead to a reduction in the quality of the cable armor. Utility Model Content

[0004] The purpose of this application is to provide a steel tape armoring machine for producing rubber-sheathed flexible cables, which solves the problem mentioned in the background art that cable armoring requires wrapping a steel coil around the outer wall of the cable during winding. However, when the cable is wound, the working line of the cable is relatively long, and the cable is prone to shaking during operation. When the tension is insufficient, the shaking is aggravated, which leads to a reduction in the quality of cable armoring.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This application provides a steel tape armoring machine for producing rubber-sheathed flexible cables, including a base plate and two sets of U-shaped frames disposed above the base plate. Two sets of drive wheels are rotatably mounted on the inner walls of the two sets of U-shaped frames. Hydraulic rods are fixedly mounted on the inner walls of the grooves of the two sets of U-shaped frames. Lifting blocks are fixedly mounted on the telescopic ends of the two hydraulic rods. Springs are sleeved on the outer walls of the two hydraulic rods. The two ends of the springs are fixedly mounted to the lifting blocks and the inner walls of the U-shaped frames, respectively. The same tensioning wheel is rotatably mounted on the inner walls of the two lifting blocks. The tensioning wheel is located between the two drive wheels. A support mechanism is provided on one side of the two sets of U-shaped frames. An armoring mechanism is provided above the base plate.

[0006] By adopting the above technical solution, the cable is threaded in a W-shape through two driving pulleys and one driven pulley. Under the elastic action of the hydraulic rod and spring, the tensioning pulley can automatically adjust its position according to the change of cable tension. When the cable is slack and the tension is insufficient, the spring pushes the lifting block to move the tensioning pulley up to tighten the cable. When the tension is too high, the spring is compressed, and the tensioning pulley moves down appropriately to relieve the tension, thereby maintaining the stable operation of the cable. This significantly improves the quality of the rubber-sheathed flexible cable armor and ensures product performance.

[0007] Optionally, the support mechanism includes a support plate fixedly installed on the upper part of the base plate, the inner wall of the support plate having a first circular hole, a first bearing being embedded in the inner wall of the support plate located inside the first circular hole, and two U-shaped frames being fixedly installed on the outer walls of the two sides of the support plate respectively.

[0008] By adopting the above technical solution, the base plate can fix the support plate, and the first circular hole on the support plate can facilitate the installation of the first bearing. Then the cable passes through the first bearing, and the first bearing can rotate inside the support plate, reducing the friction force when the cable moves.

[0009] Optionally, the armor mechanism includes a bracket fixedly mounted on the upper end of the base plate, a large bearing is embedded in the inner wall of the bracket, and a rotating disk is fixedly mounted on the inner ring wall of the large bearing.

[0010] By adopting the above technical solution, the base plate can fix the bracket, the bracket can fix the large bearing, and the large bearing can rotate the turntable.

[0011] Optionally, a stepper motor is mounted on the outer wall of the bracket, the output shaft of the stepper motor rotatably passes through the bracket, and a gear is fixedly mounted on the output shaft of the stepper motor.

[0012] By adopting the above technical solution, the bracket can fix the stepper motor, which can drive the gear to rotate. In contrast, the traditional method of fixing the stepper motor and gear is to use a coupling.

[0013] Optionally, a gear ring is fixedly installed on the outer wall of the rotating disk, and the gear meshes with the gear ring.

[0014] By adopting the above technical solution, the rotating disk can fix the gear ring, and when the gear rotates, it can drive the gear ring to rotate, which in turn can drive the rotating disk to rotate.

[0015] Optionally, the inner wall of the rotating disk is provided with a second circular hole, and a second bearing is embedded in the inner wall of the rotating disk located inside the second circular hole.

[0016] By adopting the above technical solution, the second bearing can be embedded and installed through the second circular hole inside the rotating disk. The cable passes through the second bearing, and the second bearing can rotate inside the rotating disk, reducing the friction force when the cable moves.

[0017] Optionally, a positioning seat is rotatably installed on the inner wall of the rotating disk located on both sides of the second bearing. The outer wall of the positioning seat is provided with a positioning groove. A slider is slidably connected to the inner wall of the positioning seat located inside the positioning groove. A steel drum is fixedly installed on the outer wall of the slider. The inner wall of the steel drum is slidably connected to the outer wall of the positioning seat. A threaded ring is threadedly installed on the outer wall of the positioning seat located on one side of the steel drum.

[0018] By adopting the above technical solution, the rotating disk can provide rotational support for the two positioning seats, and the positioning groove on the positioning seat can facilitate the sliding of the slider. In turn, the slider can position the steel drum, and the threaded ring can limit the movement of the steel drum.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application uses a cable that is threaded in a W-shape through two driving pulleys and one driven pulley. Under the elastic action of the hydraulic rod and spring, the tensioning pulley can automatically adjust its position according to the change of cable tension. When the cable is slack and the tension is insufficient, the spring pushes the lifting block to move the tensioning pulley up to tighten the cable. When the tension is too high, the spring is compressed and the tensioning pulley moves down appropriately to relieve the tension, thereby maintaining the stable operation of the cable. This significantly improves the quality of the rubber-sheathed flexible cable armor and ensures product performance. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This application provides a technical solution: a steel strip armoring machine for producing rubber-sheathed flexible cables, including a base plate 1 and two sets of U-shaped frames 2 set above the base plate 1. Two sets of drive wheels 23 are rotatably installed on the inner walls of the two sets of U-shaped frames 2. Hydraulic rods 3 are fixedly installed on the inner walls of the grooves of the two sets of U-shaped frames 2 respectively. Lifting blocks 5 are fixedly installed on the telescopic ends of the two hydraulic rods 3 respectively. Springs 4 are respectively sleeved on the outer walls of the two hydraulic rods 3. The two ends of the springs 4 are fixedly installed with the lifting blocks 5 and the inner walls of the U-shaped frames 2 respectively. The same tensioning wheel 6 is rotatably installed on the inner walls of the two lifting blocks 5. The tensioning wheel 6 is located between the two drive wheels 23. A support mechanism is provided on one side of the two sets of U-shaped frames 2. An armoring mechanism is provided above the base plate 1. In the technical solution of this application, the cable is passed through two driving wheels 23 and one driven wheel in a W-shape. Under the elastic action of the hydraulic rod 3 and the spring 4, the tension wheel 6 can automatically adjust its position according to the change of cable tension. When the cable is slack and the tension is insufficient, the spring 4 pushes the lifting block 5 to move the tension wheel 6 up to tighten the cable. When the tension is too high, the spring 4 is compressed and the tension wheel 6 moves down appropriately to relieve the tension, thereby maintaining the stable operation of the cable, significantly improving the quality of the rubber-sheathed flexible cable armor and ensuring product performance.

[0024] In the technical solution of this application, such as Figure 1 and Figure 3As shown, the armor mechanism includes a bracket 10 fixedly mounted on the upper end of a base plate 1. A large bearing 11 is embedded in the inner wall of the bracket 10, and a rotating disk 12 is fixedly mounted on the inner ring wall of the large bearing 11. The base plate 1 can fix the bracket 10, and the bracket 10 can fix the large bearing 11, which in turn allows the rotating disk 12 to rotate. A stepper motor 16 is mounted on the outer wall of the bracket 10. The output shaft of the stepper motor 16 rotates through the bracket 10, and a gear 17 is fixedly mounted on the output shaft of the stepper motor 16. The bracket 10 can fix the stepper motor 16, and the stepper motor 16 can drive the gear 17 to rotate. The traditional stepper motor 16 and gear 17... 7. For fixed installation, a coupling is used. A gear ring 13 is fixedly installed on the outer wall of the rotating disk 12. The gear 17 meshes with the gear ring 13. The rotating disk 12 can fix the gear ring 13. When the gear 17 rotates, it can drive the gear ring 13 to rotate, and the gear ring 13 can drive the rotating disk 12 to rotate. A second circular hole 14 is opened on the inner wall of the rotating disk 12. A second bearing 15 is embedded in the inner wall of the rotating disk 12 inside the second circular hole 14. The second bearing 15 can be embedded in the second circular hole 14 inside the rotating disk 12. The cable passes through the second bearing 15, and the second bearing 15 can rotate inside the rotating disk 12, reducing the friction force when the cable moves.

[0025] In the technical solution of this application, such as Figure 3 and Figure 4 As shown, positioning seats 18 are rotatably installed on the inner walls of the rotating disks 12 located on both sides of the second bearing 15. Positioning grooves 19 are provided on the outer walls of the positioning seats 18. A slider 21 is slidably connected to the inner wall of the positioning seat 18 located inside the positioning grooves 19. A steel drum 20 is fixedly installed on the outer wall of the slider 21. The inner wall of the steel drum 20 is slidably connected to the outer wall of the positioning seat 18. A threaded ring 22 is threadedly installed on the outer wall of the positioning seat 18 located on one side of the steel drum 20. The rotating disks 12 can provide rotational support for the two positioning seats 18, and the positioning grooves 19 on the positioning seats 18 can facilitate the sliding of the slider 21 into the positioning grooves. The slider 21 can then position the steel drum 20, and the threaded ring 22 can limit the movement of the steel drum 20.

[0026] In the technical solution of this application, such as Figure 1 and Figure 3As shown, the support mechanism includes a support plate 7 fixedly installed on the upper end of the base plate 1. The inner wall of the support plate has a first circular hole 8. A first bearing 9 is embedded in the inner wall of the support plate 7 located inside the first circular hole 8. Two U-shaped frames 2 are respectively fixedly installed on the outer walls on both sides of the support plate 7. The base plate 1 can fix the support plate 7, and the first circular hole 8 on the support plate 7 can facilitate the installation of the first bearing 9. Then the cable passes through the first bearing 9, and the first bearing 9 can rotate inside the support plate 7 to reduce the friction force of the cable movement when it passes through.

[0027] In use, during the production of rubber-sheathed flexible cables, the cable passes through the second bearing 15 and the first bearing 9, and then passes in a W-shape through the two drive wheels 23 on the two sets of U-shaped frames 2 and the tension wheel 6 located between the two drive wheels 23. External equipment wire feeding mechanism and winding mechanism are provided on both sides of the cable. With the cooperation of the winding mechanism, the cable can be moved. After production begins, the stepper motor 16 in the armor mechanism starts, and its output shaft drives the gear 17 to rotate. Since the gear 17 meshes with the toothed ring 13 on the outer wall of the rotating disk 12, the rotation of the gear 17 will drive the toothed ring 13 and the rotating disk 12 to rotate stably on the inner ring wall of the large bearing 11. At the same time, the cable moves forward continuously under the traction of the winding mechanism. When passing through the two drive wheels 23, the drive wheels 23 rotate to assist in the cable delivery. During cable transport, the hydraulic rod 3 and spring 4 work together. When the cable becomes slack or lacks tension, the spring force of spring 4 will push the lifting block 5 upward. The lifting block 5 will drive the tensioning wheel 6 upward, thereby tightening the cable and increasing its tension. When the cable tension is too high, spring 4 will be compressed, and the lifting block 5 will drive the tensioning wheel 6 downward appropriately to relieve the cable tension. This allows the tensioning wheel 6 to automatically adjust its position according to the cable tension, ensuring that the cable always maintains a stable operating state. When the rotating disk 12 rotates, the positioning seat 18, which is rotatably mounted on its inner wall, also rotates. Here, the cable is wound by traction force, or driven by an external drive motor. A steel drum 20 is sleeved on the outer wall of the positioning seat 18. The steel drum 20 is slidably positioned in the positioning groove 19 on the outer wall of the positioning seat 18 by a slider 21 and limited by a threaded ring 22. As the rotating disk 12 rotates, the steel strip on the steel drum 20 is naturally carried out and evenly wound around the outer wall of the cable, completing the armoring process of the rubber-sheathed flexible cable. In the entire process, the components work together to effectively solve the shaking problem caused by the long working line and insufficient tension during cable winding and armoring, significantly improving the quality of the rubber-sheathed flexible cable armoring and ensuring product performance.
