Description

Technical Field

[0001] The invention belongs to the technical field of optical cable production, and particularly relates to a synchronous forming device for multi-layer armors of armored optical cables. Background Art

[0002] An armored optical cable is an optical cable wrapped with a protective "armor" on the outside, mainly used to protect optical fiber cables from being bitten by animals, eroded by moisture or other damages. Armored optical cables have important applications in long-distance telecommunication optical fiber lines and primary and secondary trunk line transmissions. They are usually used to connect two optical fiber network devices inside computer rooms and buildings. The armor layer of the armored optical cable includes a rigid protective layer and an outer wrapping layer, etc. The rigid protective layer is divided into an aluminum tape winding layer and an aluminum wire winding layer. Among them, the armor layer wound with aluminum tape has stronger protection performance and is easier to process during production, so it is widely used.

[0003] When the commonly used aluminum tape armored optical cable is formed, the aluminum tape is first wound around the outer wall of the optical cable. After the aluminum tape winding is completed, the optical cable passes through an extruder for the production of the outer layer. Before the optical cable enters the extruder after the aluminum tape winding is completed, a pressing device is used to press the aluminum tape on the outer wall, which can eliminate the stress inside the aluminum tape to a certain extent after bending and make the aluminum tape wind more tightly around the outer wall of the optical cable. However, the commonly used pressing device is two symmetrically arranged rotating rollers. When in use, the optical cable passes through between the two rotating rollers, and the rotating rollers can only press the two side positions on the side wall of the optical cable. The pressing part is uneven, the stress elimination effect is poor, and the tendency of the aluminum tape to expand outwards is strong. During the subsequent extrusion process, the aluminum tape is likely to come into contact and friction with the extrusion die, affecting the setting of the protective layer. Summary of the Invention

[0018] In order to make the objectives and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present invention, and does not strictly limit the specific protection scope claimed by the present invention.

[0019] As Figure 1As shown in the figure, an armored optical cable multi-layer armor synchronous forming device includes a mounting base 1 and an L-shaped platform 2. There are two mounting bases 1, and the two mounting bases 1 are symmetrically arranged. A base frame 3 is arranged between the two mounting bases 1. Aluminum strip winding components 4 are arranged on both sides of the base frame 3, and the two aluminum strip winding components 4 are centrosymmetrically distributed. One end of the base frame 3 is snap-connected with a spiral pressing component 5. A support component 6 and an extruder 7 are fixedly installed at the top of the L-shaped platform 2. One end of the spiral pressing component 5 is rotatably connected to the top of the support component 6.

[0020] According to the above structure, when in use, the optical cable is passed through the base frame 3, the spiral pressing component 5 and the extruder 7. After the base frame 3 rotates, it drives the aluminum strip winding components 4 on both sides to wind the aluminum strip on the outer wall of the optical cable, thereby attaching armor to the optical cable. After the base frame 3 rotates, it drives the spiral pressing component 5 to rotate synchronously. When the optical cable passes through the spiral pressing component 5, the spiral pressing component 5 squeezes the armor on the outer wall of the optical cable, which can release the stress inside the aluminum strip after winding and can also make the aluminum strip wind more tightly on the outer wall of the optical cable. When the armored optical cable passes through the extruder 7, the extruder 7 extrudes rubber to synchronously armor the outer skin of the optical cable.

[0021] As Figure 3 and 4 shown, the base frame 3 includes a frame 31. The frame 31 is in the shape of a "day". Circular plates 32 are fixedly connected to both ends of the frame 31. One end of the circular plate 32 is fixedly connected with a connecting stud 33. The connecting stud 33 is rotatably connected to the top of the corresponding mounting base 1 through a bearing. A servo motor 36 is arranged at one end of the frame 31. The servo motor 36 penetrates through the frame 31, the circular plate 32 and the connecting stud 33. A servo motor 36 is fixedly installed at the bottom end of one of the mounting bases 1. Belt pulleys 37 are fixedly sleeved on the output shaft of the servo motor 36 and the side wall of one of the connecting studs 33. The two belt pulleys 37 are connected by a belt in a transmission manner. One end of one of the connecting studs 33 is fixedly connected with a cylinder 34. The inner diameter of the inner wall of the connecting cylinder 53 is equal to the outer diameter of the outer wall of the cylinder 34. A number of equally spaced convex blocks 35 are arranged on the outer wall of the cylinder 34. The number of convex blocks 35 are respectively engaged with a number of card slots 54.

[0022] According to the above structure, when armoring the optical cable, the optical cable is passed through the servo motor 36, and then the servo motor 36 is started. Through the transmission of the belt, the frame 31 is driven to rotate. After the frame 31 rotates, it drives the spiral pressing component 5 installed on the cylinder 34 to rotate, thereby pressing the armored aluminum strip.

[0023] As Figures 2 - 4As shown in the figure, the aluminum strip winding assembly 4 includes an aluminum strip mounting structure 41, a direction-changing structure 42, and a guiding structure 43.

One end of the mounting shaft 413 is fixedly connected to a threaded column 414. A second clamping plate 415 is arranged on the threaded column 414. A nut 416 for pressing the second clamping plate 415 is arranged on the side wall of the threaded column 414. The direction-changing structure 42 includes a first substrate 421 fixedly connected to one side of the frame 31. One side of the first substrate 421 is fixedly connected to a mounting cylinder 422. The top of the mounting cylinder 422 is rotatably connected to a U-shaped frame 423 through a rotating shaft. A direction-changing roller 424 is rotatably connected inside the U-shaped frame 423. Two symmetrically arranged first rotating rods 425 are rotatably connected inside the U-shaped frame 423. The guiding structure 43 includes a second substrate 431 fixedly connected to one side of the frame 31. Two corresponding first connecting plates 432 are fixedly connected to one side of the second substrate 431. One end of the first connecting plate 432 is fixedly connected to a support column 433. One end of the support column 433 is fixedly connected to a second connecting plate 434. Equally spaced second rotating rods 435 are rotatably connected between the first connecting plate 432 and the second connecting plate 434.

[0024] According to the above structure, during armoring, two aluminum strip coils are respectively placed on two mounting shafts 413, and then the aluminum strip coils are installed between the first clamping plate 412 and the second clamping plate 415 by tightening the nut 416. The aluminum strip passes through the second rotating rods 435 of the two guiding structures 43 in sequence, then bypasses from the bottom end of the direction-changing roller 424, then passes through between the two first rotating rods 425, and finally the aluminum strip is attached to the outer wall of the optical cable. The optical cable moves forward through an external traction device. As the frame 31 rotates, the two aluminum strip winding assemblies 4 rotate with the frame 31, so that the aluminum strip is wound around the outer wall of the optical cable in a spiral shape.

[0025] As Figures 4 - 6 shown in the figure, the spiral pressing assembly 5 includes two corresponding thin-walled cylinders 51. A spiral extrusion member 55 is fixedly connected between the two thin-walled cylinders 51. There are two spiral extrusion members 55, and the two spiral extrusion members 55 are distributed in a circular array around the axis of the thin-walled cylinder 51. One end of one of the thin-walled cylinders 51 is fixedly communicated with a conical cylinder 52. One end of the conical cylinder 52 is fixedly communicated with a connecting cylinder 53. A plurality of equally spaced card slots 54 are arranged at one end of the connecting cylinder 53. The spiral extrusion member 55 includes a spiral belt 551.

A spiral mounting member 552 is fixedly connected to the inner wall of the spiral belt 551. Equally spaced extrusion rollers 553 are rotatably connected inside the spiral extrusion member 55. The axis of the extrusion roller 553 is perpendicular to the tangent line of the corresponding part of the spiral mounting member 552.

[0026] According to the above structure, during use, the optical cable passes through the two spiral extrusion members 55. When the frame 31 rotates, the cylinder 34 rotates with the frame 31. The connecting cylinder 53 is snap-connected to the cylinder 34 through the cooperation of the card slot 54 and the protrusion 35. After the cylinder 34 rotates, it drives the connecting cylinder 53 to rotate, and then drives the entire spiral pressing assembly 5 to rotate synchronously with the frame 31. After the spiral belt 551 rotates, it drives the spiral mounting member 552 to rotate. After the spiral mounting member 552 rotates, the pressing roller 553 presses against the outer wall of the optical cable to press the aluminum strip on the outer wall of the optical cable. The rotation of the spiral extrusion member 55 cooperates with the forward movement of the optical cable, so that the pressing roller 553 rotates spirally along the outer wall of the optical cable, so that the aluminum strip on the outer wall of the optical cable can be extruded in the whole section, improving the effect of aluminum strip stress release, and can also improve the tightness of the aluminum strip winding.

[0027] As Figure 7 shown, the support assembly 6 includes a base 61 fixedly connected to the top of the L-shaped platform 2. A chute 62 is provided at the top of the base 61. A slider 63 is slidably connected inside the chute 62. A vertical plate 64 is fixedly connected to the top of the slider 63. A positioning member 65 for engaging the slider 63 is provided at the bottom of the base 61. An installation round hole 66 is provided in the middle of the vertical plate 64. One of the thin-walled cylinders 51 is rotatably connected inside the installation round hole 66 through a bearing. The positioning member 65 includes a sliding cavity 651 and an installation cavity 652 provided at the bottom of the base 61. There are four installation cavities 652, and the four installation cavities 652 are arranged in pairs. A sliding rod 653 is slidably connected inside the sliding cavity 651. One end of the sliding rod 653 is fixedly connected to an end head 654. The other end of the sliding rod 653 is fixedly connected to a square plate 655. One end of the square plate 655 is fixedly connected to a first spring 656. One end of the first spring 656 is fixedly connected to one end of the sliding cavity 651. A pin 657 is slidably connected to the top of the installation cavity 652. The bottom end of the pin 657 is fixedly connected to a wedge plate 658. The bottom end of the wedge plate 658 is fixedly connected to a bottom post 659. The bottom end of the bottom post 659 is fixedly connected to a second spring 6510. The bottom end of the second spring 6510 is fixedly connected to the bottom end of the installation cavity 652. Four wedge-shaped grooves 6511 are provided on the side wall of the sliding cavity 651. The four wedge plates 658 respectively penetrate through the four wedge-shaped grooves 6511. Grooves matching the pins 657 are symmetrically provided at the bottom end of the base 61.

[0028] According to the above structure, the spiral pressing assembly 5 and the base frame 3 can be separated, so as to facilitate the repair and replacement of the worn spiral pressing assembly 5. During replacement, the slide bar 653 is pressed inward by the end head 654, and the wedge-shaped groove 6511 presses the wedge-shaped plate 658 downward, so that the pin 657 moves downward. At this time, the slider 63 can slide inside the chute 62. Slide the slider 63 to the left to separate the whole spiral pressing assembly 5 from the cylinder 34, and open one end of the connecting cylinder 53, which is convenient for repairing the spiral pressing assembly 5. During reset, release the end head 654. Under the action of the first spring 656, the slide bar 653 moves to the right. Under the elastic force of the second spring 6510, the bottom column 659, the wedge-shaped plate 658 and the pin 657 move upward, and the corresponding pin 657 is inserted into the corresponding groove to position the slider 63.

[0029] The working principle of the present invention is as follows: When armoring an optical cable, the optical cable is passed through the servo motor 36, and then the servo motor 36 is started. Through the transmission of the belt, the frame 31 is driven to rotate. Two aluminum tape reels are respectively placed on two mounting shafts 413, and then the aluminum tape reels are installed between the first clamping plate 412 and the second clamping plate 415 by tightening nuts 416. The aluminum tape is sequentially passed through the second rotating rods 435 of the two guiding structures 43, then bypassed from the bottom of the deflecting roller 424, then passed through between the two first rotating rods 425, and finally the aluminum tape is attached to the outer wall of the optical cable. The optical cable moves forward through an external traction device. As the frame 31 rotates, the two aluminum tape winding assemblies 4 rotate with the frame 31, so that the aluminum tape is wound around the outer wall of the optical cable in a spiral shape. When in use, the optical cable passes through the two spiral squeezing members 55. When the frame 31 rotates, the cylinder 34 rotates with the frame 31. The connecting cylinder 53 is engaged with the cylinder 34 through the cooperation of the clamping groove 54 and the convex block 35. After the cylinder 34 rotates, it drives the connecting cylinder 53 to rotate, and further drives the entire spiral pressing assembly 5 to rotate synchronously with the frame 31. After the spiral belt 551 rotates, it drives the spiral mounting member 552 to rotate. After the spiral mounting member 552 rotates, the pressing roller 553 presses against the outer wall of the optical cable to press the aluminum tape on the outer wall of the optical cable. The rotation of the spiral squeezing member 55 cooperates with the forward movement of the optical cable, so that the pressing roller 553 rotates in a spiral shape along the outer wall of the optical cable, so that the aluminum tape on the outer wall of the optical cable can be squeezed in the whole section, improving the effect of aluminum tape stress release, and improving the tightness of aluminum tape winding. The spiral pressing assembly 5 can be separated from the base frame 3, so as to facilitate the maintenance and replacement of the worn spiral pressing assembly 5. When replacing, the slide bar 653 is pressed inward by the end head 654, and the wedge-shaped groove 6511 presses the wedge-shaped plate 658 downward, so that the pin 657 moves downward. At this time, the slider 63 can slide inside the chute 62. Slide the slider 63 to the left to separate the whole spiral pressing assembly 5 from the cylinder 34, and open one end of the connecting cylinder 53 to facilitate the maintenance of the spiral pressing assembly 5. When resetting, release the end head 654, and the slide bar 653 moves to the right under the action of the first spring 656. Under the elastic force of the second spring 6510, the bottom column 659, the wedge-shaped plate 658 and the pin 657 move upward, and the corresponding pin 657 is inserted into the corresponding groove to position the slider 63.

[0030] The above are only the preferred embodiments of the present invention.
