Description

Technical Field

[0001] The present invention relates to the technical field of optical cable processing, and particularly relates to a water-blocking tape guiding device and an optical cable processing device. Background Art

[0002] An optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It uses one or more optical fibers placed in a cladding sheath as a transmission medium and can be used individually or in groups as a communication cable assembly.

[0003] During the cladding process of the outer wall of the optical cable, in some scenarios, the horizontal wrapping method is usually selected for cladding the optical cable. The horizontal wrapping usually adopts a multi-layer winding method, and each layer of water-blocking tape will cover a part of the previous layer, forming a waterproof barrier similar to a "tile" structure. However, in the actual cladding process, the overlapping area between the water-blocking tape and the previous layer of winding may not be laid neatly due to the unevenness of the current water-blocking tape, and there may be wrinkles or unevenness, which not only affects the appearance but also may cause water to penetrate into the optical cable through the wrinkles, reducing the waterproof effect.

[0010] Preferably, the adsorption and flattening component includes a blower fan, the blower fan is fixedly connected to the side wall of the side plate, the air inlet end of the blower fan is fixedly communicated with a conveying pipe, the end of the conveying pipe away from the blower fan is fixedly communicated with a rectangular box, an arc-shaped groove is opened on the side of the rectangular box away from the blower fan, the arc-shaped groove is used to guide the water-blocking tape, and a plurality of flow holes are opened in the arc-shaped groove, and the flow holes are communicated with the rectangular box.

A plurality of inserting rods are fixedly connected to the adjusting end of the adjusting rod. Symmetrically fixed on the outer wall of the inserting rod are limit seats, and a slot for the semi-finished optical cable to pass through is provided on the limit seat. The centers of the slot and the through hole are on the same horizontal line.

[0017] The present invention also provides an optical cable processing device, which includes an optical cable semi-finished product curling device, an optical cable traction device, and also includes a water-blocking tape guiding device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] First, through the setting of the adsorption and smoothing assembly, the present invention not only guides the traveling path of the water-blocking tape, but also can make the side of the water-blocking tape expand outwards under the action of low pressure during the process of covering the outer wall of the optical cable, which helps to ensure that the water-blocking tape is as flat as possible when wound around the outside of the optical cable, is conducive to avoiding wrinkles or irregular overlaps, and can significantly improve the flatness and sealing performance of the water-blocking tape coating layer through adsorption and smoothing, thereby enhancing the waterproof protection effect of the optical cable.

[0020] Second, by forming a negative pressure in the air suction groove, the suction force generated by this negative pressure will adsorb the water-blocking tape and lift it to contact the top of the arc groove by means of the suction force. By this method, not only can the relative position between the water-blocking tape and the arc groove be maintained stable, but also it is conducive to ensuring that the side of the water-blocking tape is properly stretched and flattened under the action of the through hole, ensuring the flatness and quality of the water-blocking tape during the entire covering process. Moreover, during the process of the air suction groove adsorbing and lifting the water-blocking tape, the adsorption force generated by the air suction groove helps to maintain the overall flatness of the water-blocking tape. At the same time, the negative pressure effect during the adsorption process can effectively straighten the uneven places on the water-blocking tape, which is conducive to ensuring that it is smooth and without wrinkles when covered on the surface of the optical cable. Through cooperation with the through hole, a more effective smoothing effect can be achieved.

[0021] Third, through the setting of the adsorption hopper, the adsorption hopper will adsorb and smooth the surface of the water-blocking tape during the moving process. Even if the water-blocking tape is bent during this process, the adsorption hopper can push the water-blocking tape flat during the moving process, and the adsorption hopper can make the water-blocking tape closely fit its adsorption surface under the action of the suction force, which is conducive to maintaining the flatness when the water-blocking tape contacts the outer wall of the optical cable semi-finished product and helps to improve the sealing effect. Because, in order to avoid hindering the movement of the water-blocking tape, the adsorption hopper reduces the suction force intensity in this way. Although there may be a situation of insufficient adsorption force, under the action of the air suction groove, even if the adsorption force of the adsorption hopper fails to achieve the adsorption effect, the water-blocking tape can still be maintained in a state of fitting with the adsorption hopper under the action of the adsorption groove.

Detailed Description of the Invention

[0034] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0035] Application scenario: During the process of covering the outer wall of an optical cable, in some scenarios, the horizontal wrapping method is usually selected to cover the optical cable. The horizontal wrapping usually adopts the method of multi-layer winding. Each layer of water-blocking tape will cover a part of the previous layer, forming a waterproof barrier similar to a "tile" structure. However, during the actual covering process, the overlapping area between the water-blocking tape and the previous layer of winding may not be neatly laid due to the unevenness of the current water-blocking tape, and there may be wrinkles or unevenness, which not only affects the appearance, but may also cause moisture to penetrate into the optical cable through the wrinkles, reducing the waterproof effect.

[0036] As Figures 1 to 10 shown, a water-blocking tape guiding device includes a fence frame 1. A support and limit mechanism is arranged at the top of the fence frame 1. The support and limit mechanism is used to limit the conveying path of the semi-finished optical cable during the guiding and conveying of the semi-finished optical cable. A support frame 6 is fixedly connected to the fence frame 1. A hanging plate 2 is fixedly connected to the top of the support frame 6. A through hole 3 for the semi-finished optical cable to pass through is provided on the hanging plate 2;

[0037] A toothed ring 4 is rotatably connected to one side side wall of the hanging plate 2. A first winding plate 501 is fixedly connected to the side wall of the toothed ring 4. A winding roller 502 is rotatably connected to the side of the first winding plate 501 away from the hanging plate 2. A second winding plate 503 is rotatably connected to the side of the winding roller 502 away from the first winding plate 501. The first winding plate 501, the winding roller 502 and the second winding plate 503 together form a unwinding wheel 5;

[0038] A driving assembly is arranged at the bottom of the hanging plate 2. The driving assembly is used to drive the toothed ring 4 to rotate, so as to drive the unwinding wheel 5 to unwind the water-blocking tape, so that the water-blocking tape can be evenly wound on the outer wall of the semi-finished optical cable;

[0039] A water-blocking tape guiding mechanism is used to guide the water-blocking tape when the unwinding wheel 5 unwinds the water-blocking tape, so as to ensure that the water-blocking tape can be attached to the semi-finished optical cable on the ongoing laying path.

[0040] It should be understood that in the water-blocking tape covering process of the semi-finished optical cable, first, the optical cable passes through in a horizontal state in the order of the support and limit mechanism - through hole 3 - support and limit mechanism. Since the water-blocking tape is introduced from the outside to the production line, therefore, the two sides of the optical cable that needs to be covered with the water-blocking tape are respectively externally connected to a semi-finished optical cable curling device and an optical cable traction device to store and convey the water-blocking tape. The semi-finished optical cable curling device can unwind the optical cable, and the optical cable traction device is used to traction the optical cable to move along a predetermined route, facilitating the conveyance of the covered optical cable to a designated position;

[0041] During the manufacturing process of the optical cable, in order to ensure that the water-blocking tape can be evenly and tightly wrapped around the outer wall of the optical cable, first, a sufficient length of the water-blocking tape is pre-wound on the unwinding wheel 5, and one end of the water-blocking tape is passed through the water-blocking tape guiding mechanism so that it closely adheres to the outside of the semi-finished optical cable. When the optical cable slowly passes through a through-hole 3, the rotation of the toothed ring 4 is controlled by the driving mechanism, and the toothed ring 4 drives the unwinding wheel 5 to move in a circular motion around the optical cable, which is conducive to spirally winding the water-blocking tape onto the outer surface of the optical cable. During this process, the water-blocking tape guiding mechanism not only guides the traveling path of the water-blocking tape but also can level the two sides of the water-blocking tape to avoid the edges of the water-blocking tape overlapping or being uneven with the previously stacked parts during winding. Such a setting is conducive to ensuring that the water-blocking tape can form a smooth and wrinkle-free protective layer on the entire surface of the optical cable.

[0042] It should be noted that the driving assembly, the toothed ring 4 and the unwinding wheel 5 together form a water-blocking tape wrapping device; among them, the driving assembly includes a motor, the motor is fixedly connected to the hanging plate 2, and the output shaft end of the motor is fixedly connected with a first gear, and the first gear meshes with the toothed ring 4.

[0043] As a further embodiment of the present invention, the water-blocking tape guiding mechanism includes two side plates 33, the two side plates 33 are respectively fixedly connected to the mutually remote sides of the first winding plate 501 and the second winding plate 503, two limiting rollers 504 are rotatably connected between the two side plates 33, and adsorption and leveling components are symmetrically arranged on the two side plates 33. The adsorption and leveling components are used to adsorb and flatten the two sides of the water-blocking tape during the guiding and conveying process of the water-blocking tape to ensure that the sides are flat when fitting with the semi-finished optical cable.

[0044] It should be understood that when the water-blocking tape is introduced into the adsorption area of the adsorption and leveling component, during the process of the water-blocking tape starting to wrap the outer wall of the optical cable, the adsorption and leveling component will create a low-pressure area at the two side edges of the water-blocking tape. In this way, during the process of the water-blocking tape wrapping the outer wall of the optical cable, the side edges of the water-blocking tape will be stretched outwards under the action of the low pressure, which is conducive to ensuring that the water-blocking tape is as flat as possible when wound around the outside of the optical cable, and is conducive to avoiding wrinkles or irregular overlaps. Through adsorption and leveling, it is conducive to significantly improving the flatness and sealing performance of the water-blocking tape coating layer, thereby enhancing the waterproof protection effect of the optical cable.

[0045] As a further embodiment of the present invention, the adsorption and leveling component includes a blower fan 7, the blower fan 7 is fixedly connected to the side wall of the side plate 33, the air inlet end of the blower fan 7 is fixedly communicated with a conveying pipe 8, the end of the conveying pipe 8 away from the blower fan 7 is fixedly communicated with a rectangular box 9, an arc-shaped groove 10 is opened on the side of the rectangular box 9 away from the blower fan 7, the arc-shaped groove 10 is used to guide the water-blocking tape, and a plurality of flow holes 11 are opened inside the arc-shaped groove 10, and the flow holes 11 communicate with the rectangular box 9.

[0046] It should be understood that first, the water-blocking tape is introduced into the inside of the arc-shaped groove 10. The bending angle of the arc-shaped groove 10 is set according to the actual situation to ensure that it can fit the top of the water-blocking tape to play a guiding role. After the water-blocking tape is placed, the blower fan 7 is synchronously controlled to start. Here, it can also be realized by a negative pressure pump, etc. The blower fan 7 discharges the air inside the rectangular box 9 outward through the delivery pipe 8. The rectangular box 9 will construct a negative pressure space inside the arc-shaped groove 10 through the flow holes 11, so that the adsorption force generated by the flowing air will adsorb the side wall of the water-blocking tape. On the one hand, the suction force generated inside the arc-shaped groove 10 can effectively stretch and flatten the side of the water-blocking tape during the covering process, which is beneficial to maintaining the flatness of the water-blocking tape and then eliminating possible bends or wrinkles. On the other hand, during the adsorption process, the adsorption force is also beneficial to removing dust and impurities on the contact surface between the water-blocking tape and the optical cable. This not only helps to ensure that the water-blocking tape fits tightly and evenly on the surface of the optical cable, but also avoids problems such as poor adsorption or loose sealing caused by impurities, thus ensuring the covering quality and waterproof effect. On the third hand, the negative pressure space can help to expel the air between the water-blocking tape and the surface of the optical cable, which is beneficial to preventing the formation of bubbles or voids during the covering process. This not only improves the waterproof performance but also enhances the adhesion between the water-blocking tape and the optical cable.

[0047] As a further embodiment of the present invention, a mounting seat 12 is fixedly connected to the side wall of the rectangular box 9, a suction cylinder 13 is fixedly connected to the side wall of the mounting seat 12, a suction groove 14 is formed on the outer wall of the suction cylinder 13, and the suction cylinder 13 is fixedly communicated with the delivery pipe 8 through a connecting pipe 15.

[0048] It should be understood that in the above embodiments, the side of the water-blocking tape is adsorbed by suction to maintain the flatness of the water-blocking tape and adsorb possible impurities on the surface to keep the surface of the water-blocking tape clean. During the actual operation, in order not to hinder the movement of the water-blocking tape, the air flow through the flow holes 11 will be limited within a certain range. At this time, the position of the water-blocking tape and the flow-through hole 3 needs to be within a suitable range. However, during the process of guiding and transporting the water-blocking tape, the position between the water-blocking tape and the arc-shaped groove 10 may change, which may affect the adsorption effect. Therefore, an air suction cylinder 13 is installed and communicated with the conveying pipe 8 through a connecting pipe 15. During operation, the air suction cylinder 13 continuously evacuates the internal air, thereby forming a negative pressure in the air suction groove 14. The suction force generated by this negative pressure will adsorb the water-blocking tape and lift it to contact the top of the arc-shaped groove 10 by means of the suction force. By this method, not only can the relative position between the water-blocking tape and the arc-shaped groove 10 be maintained stable, but also it is beneficial to ensure that the side of the water-blocking tape is properly stretched and flattened under the action of the flow-through hole 3, ensuring the flatness and quality of the water-blocking tape during the entire wrapping process. Moreover, during the process of the air suction groove 14 adsorbing and lifting the water-blocking tape, the adsorption force generated by the air suction groove 14 helps to maintain the overall flatness of the water-blocking tape. At the same time, the negative pressure effect during the adsorption process can effectively straighten the uneven parts on the water-blocking tape, which is beneficial to ensure that it is smooth and wrinkle-free when wrapped around the surface of the optical cable. Through cooperation with the flow-through hole 3, a more effective flattening effect can be achieved.

[0049] As a further embodiment of the present invention, an electric push rod 16 is fixedly connected inside the air suction cylinder 13. The telescopic end of the electric push rod 16 is fixedly connected with a connecting cylinder 17. A plurality of air inlets 18 are opened on the outer wall of the connecting cylinder 17. The bottom end of the connecting cylinder 17 is provided with an adsorption hopper 19 through a connecting member, and the adsorption hopper 19 is located inside the air suction groove 14.

[0050] It should be understood that in the above-mentioned embodiment, it is mentioned that the water-blocking tape is adsorbed and lifted by the air suction groove 14, so that the water-blocking tape contacts the end of the arc groove 10 and maintains the relative position relationship with the flow hole 3. However, in the actual operation process, if no additional force is applied to the outside, and only the suction force generated by adsorption is relied upon to smooth the water-blocking tape, the effect may not be good for those with more bends and wrinkles. Therefore, when the air inside the air suction groove 14 is discharged to the outside, the air will also be discharged through the adsorption bucket 19, the connecting tube 17, and the air inlet 18, so that the adsorption bucket 19 adsorbs the water-blocking tape. After the adsorption is completed, the electric push rod 16 is controlled to start working, and the connecting tube 17 is driven to move by the electric push rod 16, and the connecting tube 17 drives the adsorption bucket 19 to move through the connecting piece. During the movement of the adsorption bucket 19 The surface of the water-blocking tape will be adsorbed and smoothed. Even if the water-blocking tape is bent during this process, the adsorption bucket 19 can flatten the water-blocking tape during the movement, and the adsorption bucket 19 can make the water-blocking tape fit closely with its adsorption surface under the action of suction, which is beneficial to maintain the flatness of the water-blocking tape when it contacts the outer wall of the semi-finished optical cable, and helps to improve the sealing effect. The adsorption bucket 19 can also smooth and compact the overlapping area to achieve a better sealing effect. Because, in order to avoid hindering the movement of the water-blocking tape, the adsorption bucket 19 adopts this method to reduce the suction strength. Although there may be a situation of insufficient adsorption force, under the action of the suction groove 14, even if the adsorption force of the adsorption bucket 19 cannot achieve the adsorption effect, the adsorption effect of the adsorption groove can maintain the state in which the water-blocking tape and the adsorption bucket 19 are in contact.

[0051] As a further implementation scheme of the present invention, the top end of the connecting cylinder 17 is rotatably connected to a second gear 20, the second gear 20 is fixedly connected to a curved shielding plate 21 on one side close to the adsorption bucket 19, and the interior of the suction cylinder 13 is fixedly connected to a rack 22, which meshes with the second gear 20.

[0052] It should be understood that in the above example, it is described that the overly bent water-blocking belt is adsorbed by the adsorption hopper 19 and the air suction groove 14 to achieve a flattening effect. However, during the process of the adsorption hopper 19 gradually moving from the surface of the water-blocking belt to the side, the adsorption hopper 19 will also drive the connecting cylinder 17 to move, the connecting cylinder 17 drives the second gear 20 to move, and the second gear 20 drives the arc-shaped baffle 21 to move. After moving to a predetermined position, the second gear 20 will drive the arc-shaped baffle 21 to rotate. As the arc-shaped baffle 21 gradually moves away, more air inlets 18 are exposed, which leads to an increase in the air flow rate through the adsorption hopper 19, thereby enhancing the adsorption force; when approaching the side of the water-blocking belt, this enhanced adsorption force can more effectively flatten the curled edges and wrinkles to ensure the flatness of the water-blocking belt; during the return process, in order to avoid the adsorption hopper 19 having a negative impact on the flatness of the water-blocking belt and preventing it from driving the water-blocking belt to have a rewinding phenomenon, the rack 22 will drive the arc-shaped baffle 21 to cover part of the air inlets 18 again, which can reduce the number of air inlets 18, thereby reducing the adsorption force of the adsorption hopper 19, which is beneficial to avoiding unnecessary traction on the water-blocking belt during the movement and return of the adsorption hopper 19, and can ensure the flatness and stability of the water-blocking belt, ensuring that the water-blocking belt is not pulled or deformed when the adsorption hopper 19 returns to its original position and maintaining its original flat state. Through the above design, not only the flatness of the water-blocking belt during the coating process is ensured, but also the negative effects that may occur during the return process are effectively prevented.

[0053] As a further embodiment of the present invention, the connecting member includes a universal ball 23. The universal ball 23 is fixedly connected to the connecting cylinder 17. A plurality of drainage holes 24 are formed in the universal ball 23. The drainage holes 24 communicate with the connecting cylinder 17. The universal ball 23 is rotatably connected to the adsorption hopper 19, and the drainage holes 24 communicate with the adsorption hopper 19. A spring 25 is fixedly connected between the connecting cylinder 17 and the adsorption hopper 19, and the spring 25 is sleeved on the universal ball 23.

[0054] It should be understood that by forming drainage holes 24 in the universal ball 23, a connection is formed among the adsorption hopper 19, the drainage holes 24, and the connecting cylinder 17, which is beneficial to the flow of air.

[0055] As a further embodiment of the present invention, a push rod 26 is fixedly connected to the side of the arc-shaped baffle 21 close to the adsorption hopper 19. A circular ring 27 is fixedly connected to the side of the adsorption hopper 19 close to the push rod 26. The circular ring 27 is provided with an inclined opening 28, and the push rod 26 is matched with the inclined opening 28.

[0056] It should be understood that during the process of the adsorption hopper 19 moving towards the side of the water-blocking belt, in order to further process the curled edge, the ejector rod 26 is provided, so that the ejector rod 26 moves synchronously with the arc-shaped baffle 21. When the arc-shaped baffle 21 drives the ejector rod 26 to move, under the guidance of the inclined opening 28, it will push the adsorption nozzle to deflect, thereby using the bending force generated by the deflection to bend the side of the water-blocking belt, which helps to further smooth the side of the water-blocking belt.

[0057] As a further embodiment of the present invention, the support and limit mechanism includes an adjusting rod 29. The adjusting rod 29 is fixedly connected to the top of the fence frame 1. A plurality of inserting rods 30 are fixedly connected to the adjusting end of the adjusting rod 29. Symmetrically fixed on the outer wall of the inserting rod 30 are limit seats 31. A slot hole 32 for the semi-finished optical cable to pass through is provided on the limit seat 31. The center of the slot hole 32 and the through hole 3 are on the same horizontal line.

[0058] It should be understood that the semi-finished optical cable sequentially passes through the slot hole 32 and the through hole 3, and the semi-finished optical cable is limited by the setting of the slot hole 32, which is beneficial to maintaining the moving track of the optical cable and its flatness, and helps the subsequent coating process.

[0059] This application also includes an optical cable processing device, as Figure 11 shown, including a semi-finished optical cable curling device, an optical cable traction device, and a water-blocking belt guiding device.

[0060] It should be understood that the optical cable traction device provides power for the movement of the semi-finished optical cable, and a water-blocking belt guiding device is arranged between the semi-finished optical cable curling device and the optical cable traction device. The water-blocking belt guiding device includes a water-blocking belt guiding mechanism and a water-blocking belt wrapping device, so that while guiding the water-blocking belt, the water-blocking belt can be completely wrapped on the surface of the optical cable.

[0061] The working principle of the present invention:

[0062] In the process of wrapping the water-blocking belt of the semi-finished optical cable, first, the optical cable passes through in sequence according to the order of the support and limit mechanism - through hole 3 - support and limit mechanism in a horizontal state. Since the water-blocking belt is introduced into the production line from the outside, therefore, the two sides of the optical cable that needs to be wrapped with the water-blocking belt are respectively externally connected to the semi-finished optical cable curling device and the optical cable traction device to store and transport the water-blocking belt. The semi-finished optical cable curling device can unwind the optical cable, and the optical cable traction device is used to traction the optical cable to move along a predetermined route, which is convenient for transporting the wrapped optical cable to a designated position;

[0063] During the manufacturing process of an optical cable, in order to ensure that the water-blocking tape can be evenly and tightly wrapped around the outer wall of the optical cable. First, a sufficient length of the water-blocking tape is pre-wound on the unwind reel 5, and one end of the water-blocking tape is passed through the water-blocking tape guiding mechanism of the water-blocking tape to make it close to the outside of the semi-finished optical cable. When the optical cable slowly passes through a through-hole 3, the rotation of the gear ring 4 is controlled by the driving mechanism. The gear ring 4 drives the unwind reel 5 to move in a circular motion around the optical cable, which is conducive to spirally winding the water-blocking tape onto the outer surface of the optical cable. During this process, the water-blocking tape guiding mechanism not only guides the traveling path of the water-blocking tape, but also can level the two sides of the water-blocking tape, which is beneficial to avoiding the overlap or unevenness between the edges of the water-blocking tape and the previously laminated parts during winding. Through such a setting, it is beneficial to ensure that the water-blocking tape can form a smooth and wrinkle-free protective layer on the entire surface of the optical cable.
