Description

Technical Field

[0001] The utility model relates to the technical field of special equipment for optical cable manufacturing, and particularly relates to an optical cable gluing system and its manufacturing equipment. Background Art

[0002] An optical cable is a transmission medium that organically combines metal wires and optical fibers. It can transmit electrical energy and optical information simultaneously on the same path. Under this structure, the integration of power flow, service flow, and information flow is realized, greatly shortening the construction period, reducing the construction cost, saving resources, and laying a solid foundation for the construction of smart grids. Therefore, optical cables are widely used.

[0003] In the final cable stranding step of the optical cable, the stranding process is usually adopted. In this step, optical fibers and metal wires are stranded together to form the basic structure of the optical cable. For example, the patent with the application publication number CN 103413621A discloses a processing system for the conductor core of a power communication optical cable, including a central pay-off reel and a take-up reel. Between the central pay-off reel and the take-up reel, a stranding cage, a gluing device, a bunching die, a glue smoothing device, a curing device, a traction device, etc. are arranged in sequence.

[0004] Among them, the glue output by the gluing device can fill the gaps between multiple strands of cables, improving the overall water tightness of the optical cable. Therefore, the gluing device is an important device in the stranding process. However, due to the short maintenance cycle of the gluing device in the prior art, this situation is caused by various reasons. For example, the glue used in the gluing device is usually a curing glue. During use, some curing glue often adheres to the inner wall of the gluing device without participating in the stranding process. Such curing glue is easy to cure on the inner wall, resulting in the need to stop the operation of the gluing device after running for a certain period of time to replace relevant parts or clean the cured curing glue; the glue supply device in the gluing device may have insufficient glue supply, and it is necessary to stop the operation of the gluing device to supplement the glue in the glue supply device, etc.

[0005] With the continuous increase in the market demand for optical cables, the processing efficiency requirements for optical cables are also increasing. However, during the maintenance period of the gluing device, it is necessary to stop the overall operation of the optical cable manufacturing equipment, which will inevitably affect the overall manufacturing efficiency of the optical cable. Therefore, there is an urgent need in the market for an optical cable gluing device with a short maintenance cycle to improve the overall manufacturing efficiency of optical cables. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide an optical cable gluing system that can prevent a large amount of curing glue from adhering and curing on the inner wall, enabling the optical cable gluing system to operate for a long time, thereby reducing the overall maintenance times of the optical cable gluing system and improving the working efficiency of the optical cable gluing system.

[0007] The present utility model is realized through the following technical solutions.

[0008] An optical cable gluing system, characterized in that it comprises:

[0009] A gluing device for coating glue on the surface of a cable, including an inlet, an outlet, and a guiding surface connecting the inlet and the outlet to form a gluing channel penetrating the gluing device, and further including a glue inlet channel disposed at the top of the gluing channel; wherein the guiding surface is the main part where solidified adhesive adhesion occurs.

[0010] A glue supply device for supplying glue to the gluing device through the glue inlet channel.

[0011] A glue cleaning device for removing the glue adhered to the guiding surface, including a scraping member movably disposed in the gluing channel, one end of the scraping member that fits the guiding surface is the scraping end, and the other end away from the guiding surface is the falling end.

[0012] The working cycle of the scraping member includes the whole process of running from the bottom of the gluing channel to the top of the gluing channel, during which the glue adhered to the guiding surface will be scraped. When the scraping member is placed at the top of the gluing channel, the falling end is closer to the center position of the gluing channel than the scraping end, that is, the falling end is placed below the scraping end, and the glue scraped by the scraping member will flow to the falling end under the influence of gravity and finally drip back into the gluing channel.

[0013] In the overall manufacturing process of an optical cable, the stranding step is usually connected immediately after the gluing step. Therefore, when entering the inlet of the gluing channel, the distance between each strand of cable is relatively large, while near the outlet, the distance between each strand of cable is smaller and approaches to form a whole optical cable.

[0014] Therefore, when the scraping member moves to the top of the gluing channel, one end of the falling end close to the inlet is higher than the other end close to the outlet, then it can guide the glue located at or near the falling end to flow towards the position close to the outlet and finally drip at the position close to the outlet. In this case, the probability of the glue directly dripping onto the cable increases, enabling the glue adhered to the guiding surface to be reused instead of falling back onto the guiding surface again after being scraped.

[0015] As a further improvement of the present utility model, the scraping member includes a first scraping plate and a second scraping plate. When the first scraping plate and the second scraping plate move to the top or bottom of the gluing channel, the first scraping plate and the second scraping plate fit together.

[0016] Wherein, the process of the first squeegee and the second squeegee moving from the bottom of the glue application channel to the top of the glue application channel is the working cycle, and the movement trajectories of the first squeegee and the second squeegee in their respective working cycles are opposite to each other;

[0017] Then, when the first squeegee and the second squeegee approach each other at the top of the glue application channel, the glue scraped off between the two will be continuously squeezed, and the glue will be extruded from between the two after they are joined, and the extruded glue will be more likely to flow to the falling-back end and finally complete the process of dripping onto the cable;

[0018] The process of the first squeegee and the second squeegee moving from the top of the glue application channel to the bottom of the glue application channel is the return cycle, and the movement trajectories of the first squeegee and the second squeegee in their respective return cycles are opposite to the movement trajectories of their respective working cycles;

[0019] Wherein, the movement trajectory is represented by the movement trajectory direction, the movement trajectory form and the movement amplitude, so the movement trajectory has directionality.

[0020] When the first squeegee and the second squeegee move back to the bottom of the glue application channel, the two will respectively scrape the passing guiding surface again to prevent some glue from not being scraped off during the working cycle. And when the first squeegee and the second squeegee approach each other at the bottom of the glue application channel, the glue scraped off between the two will still be continuously squeezed, and the glue will be extruded from between the two after they are joined, but at this time the extruded glue will flow to both sides of the squeegee member to facilitate scraping the glue to the top of the glue application channel in the next working cycle.

[0021] As a further improvement of the present utility model, guiding inclined surface structures are provided on the falling-back ends of the first squeegee and the second squeegee. When the first squeegee and the second squeegee are joined at the bottom of the glue application channel, the guiding inclined surface structures are away from the joining part of the first squeegee and the second squeegee.

[0022] When the first squeegee and the second squeegee are joined at the bottom of the glue application channel, the guiding inclined surface structures guide the extruded glue to flow to both sides of the squeegee member; and when the first squeegee and the second squeegee are joined at the top of the glue application channel, their guiding inclined surface structures instead form a structure similar to a guiding groove, which will further guide the glue to flow in the guiding groove to a position near the wire outlet and then drip.

[0023] As a further improvement of the present utility model, the glue cleaning device further includes a driving device. A transmission block is connected to one end of the squeegee member near the wire outlet, and the transmission block is adapted to the driving device.

[0024] As a further improvement of the present utility model, a glue delivery channel is further provided on the glue scraping member. When the glue scraping member is placed on the top of the glue coating channel, the glue delivery channel communicates with the glue inlet channel for accommodating the passage of the glue.

[0025] As a further improvement of the present utility model, the cross-sectional dimension of the wire inlet is larger than that of the wire outlet. Since the spacing between the strands of the cable is smaller near the wire outlet, in this structure, the guiding surface near the wire outlet is closer to the cable, that is, the glue scraping member in the glue coating channel is also close to the cable, which is more conducive to the glue drops on the falling end dropping onto the cable.

[0026] As a further improvement of the present utility model, a connection port is formed at the connection between the glue inlet channel and the glue coating channel. The first distance between the connection port and the wire outlet is smaller than the second distance between the connection port and the wire inlet, that is, the glue inlet channel is closer to the wire outlet.

[0027] In the glue adding process of the optical cable, the curing glue used has viscoelasticity, which can exhibit both viscosity (i.e., fluid properties, such as flowing) and elasticity (i.e., solid properties, such as maintaining shape). Therefore, after the glue enters the glue coating channel, it is easy to form a lump structure in the glue coating channel instead of flowing away directly.

[0028] Therefore, in this structure, the lump glue will appear at the position near the wire outlet. On the one hand, when some of the glue drops in the lump glue drop to the bottom of the glue coating channel, it is far from the wire inlet, and it can be scraped up by the glue scraping member during its flow towards the wire inlet. On the other hand, during the flow of the glue on the falling end towards the wire outlet, dripping may occur. In this structure, the probability of the glue drops falling into the lump glue is increased, which can also improve the utilization rate of the glue.

[0029] As a further improvement of the present utility model, the glue supply device includes:

[0030] At least two glue storage parts for storing the glue;

[0031] A communication part including a main channel, several branch channels and start-stop valves provided on the branch channels. One end of the branch channel is connected to the glue storage part, and the other end is connected to the main channel;

[0032] A glue outlet provided on the main channel for outputting the glue;

[0033] A glue supply system for providing pressure to the glue storage part to output the glue stored in the glue storage part. In this structure, it can ensure that the glue supply device can stably supply glue for a long time and prevent the situation of the glue adding system shutting down due to insufficient glue volume.

[0034] As a further improvement of the present utility model, a glue quantity detection device is provided in the glue supply device, and the glue quantity detection device is linked to the control device, and the control device is used to control the opening and closing state of the start-stop valve and the on-off state of the pressure supply system.

[0035] An optical cable manufacturing device, characterized in that it includes the optical cable glue adding system described in any of the above.

[0036] The beneficial effects of the present utility model include:

[0037] (1) By providing a glue cleaning device to scrape the glue on the guiding surface, the situation where glue adheres to the guiding surface and solidifies is reduced, thereby preventing the need to clean the glue coating device after a short period of use, and ensuring the long-term stable operation of the glue adding system;

[0038] (2) While scraping the glue, the glue cleaning device can reuse the scraped glue during the glue adding operation, greatly improving the utilization rate of the glue and reducing the loss cost of the glue adding operation;

[0039] (3) Through the improvement of the glue supply device, it is ensured that the required glue can be stably output for a long time, preventing the shutdown of the glue adding system caused by insufficient glue supply. Description of the Drawings

[0049] Among Figures 1 - 3 them, to more clearly show the structure of the glue cleaning device, the transmission block part is removed, which does not affect the scope of protection of the claims of the present utility model. Specific embodiments

[0050] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] The orientation terms such as upper, lower, left, right, front, rear, front side, back side, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0052] The optical cable is prepared by stranding multiple optical fibers and cables. In this embodiment, for the convenience of description, before the stranding step is completed, the optical fibers and cables are collectively referred to as cable α.

[0053] As shown in the patent with the application publication number CN 103413621A, which is an existing technology, in the usual preparation steps of an optical cable, the parallel wire die is arranged after the glue adding system. Therefore, in the glue adding system, multiple strands of cable α show a stranding trend. Specifically, multiple strands of cable α rotate forward in the glue adding system and the gap between them continuously decreases.

[0054] Embodiment 1:

[0055] An optical cable glue adding system, as Figures 1 - 4 and Figure 7 shown, includes a glue coating device 1, a glue supply device 2, and a glue cleaning device 3.

[0056] Among them, the glue coating device 1 is used to coat glue on the surface of the cable α, and includes an inlet 101, an outlet 102, and a guiding surface 103 connecting the inlet 101 and the outlet 102. The structure of the guiding surface 103 enables a glue coating channel 4 to be formed throughout the glue coating device 1, and multiple strands of the cable α pass through the glue coating channel 4 to complete the glue coating work. The glue coating device 1 also includes a glue inlet channel 104 disposed on its top, and the glue inlet channel 104 communicates with the glue coating channel 4, which can ensure that the glue provided by the glue supply device 2 flows into the glue coating channel 4, thereby ensuring the stable progress of the glue coating work.

[0057] As Figures 5 - 6 shown, below the connection port of the glue coating channel 4 and the glue inlet channel 104 is usually the formation position of the agglomerated glue β. Multiple strands of the cable α pass through the agglomerated glue β during movement to complete the coating of the glue on the surface of the cable α. During this period, the cable α will also stir the agglomerated glue β. Therefore, the glue adhering to the guiding surface 103 mainly comes from two aspects. One part is that part of the glue in the agglomerated glue β drips to the bottom of the glue coating channel 4 under the influence of its own gravity, and the other part splashes to the side of the glue coating channel 4 and finally adheres to the guiding surface 103 on the side of the glue coating channel 4 after being stirred by the cable α.

[0058] The glue cleaning device 3 is used to clean the glue adhering to the guiding surface 103, and includes a scraping member 301 movably disposed in the glue coating channel 4. One end of the scraping member 301 that fits the guiding surface 103 is the scraping end 301-1, and the other end away from the guiding surface 103 is the falling end 301-2. When the scraping member 301 moves, the scraping end 301-1 can scrape off the glue on the guiding surface 103; when the scraping member 301 moves to the top of the glue coating channel 4, under the influence of the gravity of the glue itself, it can guide the glue to drip into the glue coating channel 4 from the falling end 301-2. During the dripping process of the glue, the glue may directly contact the cable α or drip back into the agglomerated glue β located in the glue coating channel 4.

[0059] When the scraping member 301 moves to the top of the glue coating channel 4, one end of the falling end 301-2 close to the inlet 101 is higher than the other end close to the outlet 102. Therefore, the glue located on or near the falling end 301-2 will be guided to move towards the position of the outlet 102 and finally drip near the outlet 102. Under this structure, the probability of the glue directly dripping onto the cable α is increased.

[0060] Among them, the scraping member 301 can be one or more members of any shape. However, since the scraping end 301-1 of the scraping member 301 can scrape the glue on the guiding surface 103, the scraping end 301-1 needs to be everywhere in contact with the guiding surface 103.

[0061] The working cycle of the glue scraping member 301 starts from the bottom of the glue application channel 4 and ends when it moves to the top of the glue application channel 4. Then it can enter the retention cycle of the glue scraping member 301 to facilitate the falling back of the scraped glue. After the working cycle or the retention cycle ends, the glue scraping member 301 enters the return cycle, and the glue scraping member 301 moves back from the top of the glue application channel 4 to the bottom of the glue application channel 4.

[0062] If the glue scraping member 301 is a complete member, then during the return cycle, the direction of the movement trajectory of the glue scraping member 301 is the same as that in the working cycle, so as to scrape the part of the guiding surface 103 that was not involved in the previous working cycle during the return cycle, and the scraped glue will also be scraped to the top of the glue application channel 4 during the next working cycle; if the glue scraping member 301 comprises multiple members, then the direction of the movement trajectory of each member during the return cycle can be different from that in the working cycle.

[0063] The presence of the glue cleaning device 3 can prevent a large amount of glue from adhering to the guiding surface 103, which may cause the glue application device 1 to need to be shut down urgently for glue cleaning after being used for a period of time, greatly increasing the time interval between two maintenance operations and ensuring the long-term stable operation of the glue adding system.

[0064] Preferably, as Figures 1 - 3 shown, the glue scraping member 301 comprises a first glue scraping plate 301a and a second glue scraping plate 301b. When the first glue scraping plate 301a and the second glue scraping plate 301b move to the top or bottom of the glue application channel 4, the first glue scraping plate 301a and the second glue scraping plate 301b are in contact with each other.

[0065] In this embodiment, when observing from the position of the wire inlet 101 towards the wire outlet 102, during the working cycle, the first glue scraping plate 301a moves in the clockwise direction, while the second glue scraping plate 301b moves in the counterclockwise direction. During the working cycle, the glue on the guiding surface 103 is respectively scraped towards the top of the glue application channel 4. After the two are in contact with each other at the top of the glue application channel 4, the glue between them is extruded and made to drip back into the glue application channel 4.

[0066] During the return cycle, the first glue scraping plate 301a moves in the counterclockwise direction, while the second glue scraping plate 301b moves in the clockwise direction until the two are in contact with each other at the bottom of the glue application channel 4. The movement trajectories of the two during the return cycle are opposite to their movement trajectories during their respective working cycles. During the return cycle, the two scrape the glue that still remains on the guiding surface 103 again. After the two are in contact with each other, the scraped glue will be extruded and flow onto the falling-back end 301-2 or overflow to both sides of the glue scraping member 301. Then during the next working cycle, such glue will be scraped and moved to the top of the glue application channel 4 again and finally drip back into the glue application channel 4.

[0067] Preferably, as Figures 1 - 3 shown, guiding inclined plane structures 301-3 are provided on the falling ends 301-2 of the first glue scraping plate 301a and the second glue scraping plate 301b. When the first glue scraping plate 301a and the second glue scraping plate 301b are in contact with each other at the bottom of the glue coating channel 4, the guiding inclined plane structures 301-3 are away from the contact portion of the first glue scraping plate 301a and the second glue scraping plate 301b. Then, in the return cycle, the guiding inclined plane structures 301-3 can guide the glue extruded between the two to flow to both sides of the glue scraping member 301.

[0068] In the working cycle, when the first glue scraping plate 301a and the second glue scraping plate 301b are in contact with each other at the top of the glue coating channel 4, the guiding inclined plane structures 301-3 of the two can form a structure similar to a guiding groove. The glue extruded by the first glue scraping plate 301a and the second glue scraping plate 301b falls into the guiding groove. Since the contact area between the glue and the falling end 301-2 increases, the glue will not directly drip, and then under the influence of its own gravity, it flows to the position where the wire outlet 102 is located and finally drips at a position close to the wire outlet 102. The probability of the glue dripping onto the cable α is increased.

[0069] Preferably, as Figures 5 - 6 shown, a transmission block 302 is connected to one end of the glue scraping member 301 close to the wire outlet 102. The transmission block 302 can protrude from the wire inlet 101 and is connected to the driving device in the glue cleaning device 3. So that the driving device can drive the overall movement of the glue scraping member 301 through the rotating block. The driving device can be any mechanical driving device, which is a well-known implementation method for those skilled in the art, so it will not be described in detail in this embodiment.

[0070] Preferably, as Figure 1 and Figure 4 shown, a glue conveying channel 301-4 is further provided on the glue scraping member 301. Since after the working cycle, the glue scraping member 301 may enter a retention cycle to facilitate the falling back of the glue. The setting of the glue conveying channel 301-4 can ensure that when the glue scraping member 301 is placed at the top of the glue coating channel 4, the glue conveying channel 301-4 is communicated with the glue inlet channel 104 to accommodate the glue passing through and ensure a constant input of glue into the glue coating channel 4. At the same time, combined with the structure of the glue scraping member 301, part of the glue flowing towards the wire outlet 102 can directly flow in parallel with the input glue when flowing through the glue conveying channel 301-4, so as to return to the mass of glue β.

[0071] Preferably, as Figure 3As shown, the cross-sectional dimension of the inlet 101 is larger than that of the outlet 102. In this embodiment, the cross-sections of both the inlet 101 and the outlet 102 are circular, so that the glue application channel 4 as a whole forms a frustum-like structure. In this structure, the guiding surface 103 always adheres closely to the cable α, and the falling-back end 301-2 on the glue scraping member 301 that abuts against the guiding surface 103 also adheres more closely to the cable α, making it easier and faster for the glue droplets to directly fall onto the cable α or drip back into the mass of glue β after dripping.

[0072] Preferably, as Figure 6 shown, a connection port is formed at the connection between the glue inlet channel 104 and the glue application channel 4, and the first distance between the connection port and the outlet 102 is smaller than the second distance between the connection port and the inlet 101, that is, the glue inlet channel 104 is closer to the outlet 102. In this structure, the mass of glue β can be formed at a position close to the outlet 102. Then, after being matched with the structure of the glue scraping member 301, when the glue moves to the falling-back end 301-2 close to the outlet 102 and drips, it is easier to drip onto the mass of glue β, which can also improve the utilization rate of the glue and prevent the glue from dripping onto the guiding surface 103 again.

[0073] Embodiment 2:

[0074] The difference between this embodiment and Embodiment 1 is that, as Figure 7 shown, in this embodiment, the glue supply device 2 includes two glue storage parts 201, a communication part 202, a glue outlet 203 and a pressure supply system.

[0075] Among them, in this embodiment, since there are only two glue storage parts 201, the main channel 202-1 and the branch channel 202-2 in the communication part 202 are arranged on the same straight line, the start-stop valve is arranged on the branch channel 202-2, and the glue outlet 203 is arranged on the main channel 202-1. Those skilled in the art can easily know that in the case of only two glue storage parts 201, using a single pipe and setting start-stop valves at both ends of the pipe close to the glue storage parts 201 can also achieve the corresponding effect. Therefore, the essence of such technical solutions does not deviate from the scope of the technical solutions of each embodiment of the present invention.

[0076] If there are three or more glue storage parts 201 in the glue supply device 2, one end of the branch channel 202-2 is connected to the glue storage part 201, and the other end is connected to the main channel 202-1, so that the branch pipe can guide the glue to be input into the main channel 202-1, and finally the glue is output through the glue outlet 203 on the main pipe.

[0077] The pressure supply system is arranged on the glue storage part 201, and can provide pressure in the glue storage part 201 to squeeze the glue stored in the glue storage part 201 into the branch channel 202-2, and finally achieve the effect of outputting the glue.

[0078] When one of the glue storage parts 201 supplies glue, the start-stop valves on the remaining branch channels 202-2 are closed, and the pressure supply systems on the remaining glue storage parts 201 do not supply pressure. When the glue in the glue storage part 201 is almost used up, the start-stop valves on the branch channels 202-2 connected to any one of the remaining glue storage parts 201 storing glue can be opened, as well as the pressure supply system of this glue storage part 201, and at the same time, the start-stop valves on the branch channels 202-2 of the current glue storage part 201 are closed, so that the new glue storage part 201 starts to undertake the glue supply work. During the process of the new glue storage part 201 supplying glue, glue can be replenished for the previous glue storage part 201.

[0079] The glue supply device 2 of this device can ensure the long-term stable output of glue and prevent the shutdown of the glue adding system caused by insufficient glue volume.

[0080] Preferably, a glue volume detection device is provided in the glue supply device 2. This device can be a weight detection device for the glue storage part 201 to detect the overall weight of the glue storage part 201. When the overall weight of the glue storage part 201 is lower than the corresponding index, it indicates that the glue volume is tending to be insufficient; if the structure of using an extended pressure rod to extrude the glue in the glue storage part 201 is adopted in the pressure supply system, as Figure 7 shown, the glue volume detection device can adopt a structure for detecting the extended length of the pressure rod, etc., to detect the remaining amount of glue in the glue storage part 201.

[0081] The control device can control the opening and closing states of the start-stop valves. The relevant structure of the control device is a well-known implementation method for those skilled in the art, so it will not be elaborated in this embodiment. The control device is linked to the glue volume detection device. When the glue volume detection device detects that the glue volume in the glue storage part 201 is insufficient, the control system will control the start-stop valve on the branch pipeline of the current glue storage part 201 to close and the corresponding pressure supply system to close, while the start-stop valve on the branch pipeline of any one of the remaining glue storage parts 201 is opened and the pressure supply system is opened, so as to ensure the automatic long-term stable supply of glue.

[0082] Compared with manually recording the usage time of the glue storage part 201 and converting it to determine whether it is used up and thus requiring the switching work of the glue storage part 201, after setting the glue volume detection device and linking it to the control device, the switching work of the glue storage part 201 is more accurate and can better ensure the long-term stable operation of the glue supply device 2.

[0083] Embodiment 3:

[0084] An optical cable manufacturing device includes the optical cable glue adding system described in any one of Embodiments 1-2.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model.
