Description

[0002] As the core medium for information transmission, the improvement of optical fiber production quality and efficiency is the focus of industry attention. In the optical fiber manufacturing process, the coating process is one of the key links to ensure the stability of optical fiber performance and extend its service life. As a protective layer on the surface of the optical fiber, the coating layer must not only have good mechanical strength to protect the optical fiber from external damage, but also ensure the stability of optical performance. This requires strict control of key parameters such as viscosity and thickness of the coating during the coating process to achieve uniformity and high quality of the coating layer.

[0003] The paint feeding system widely used in the current optical fiber production field generally adopts a high-pressure diaphragm pump to centrally feed the main pipeline of the workshop. Although it meets the needs of large-scale production to a certain extent, it exposes many limitations in actual operation. The system is particularly inconvenient when conducting new paint tests. Since all production lines share a set of paint systems, the test requirements of any production line require the entire system to stop and cooperate, and the pipeline must be fully cleaned. This process is not only time-consuming and labor-intensive, but also greatly reduces production efficiency and increases production costs. In addition, the high-pressure feeding method is prone to bubbles during the transfer of paint from barrels to material tanks, which affects the quality of the paint; and the wear problem caused by the frequent start and stop of the diaphragm pump further increases maintenance costs and production risks.

[0004] In view of this, a more flexible, efficient and cost-controllable coating feeding solution is needed to significantly improve the flexibility and efficiency of optical fiber production while ensuring coating quality. Summary of the invention

[0005] The purpose of this application is to provide a feeding system for optical fiber production, which can supply multiple production lines at the same time, and can also meet the production line to test different coatings, without stopping all the lines to replace the coatings, and can also avoid the generation of bubbles in the coatings.

[0019] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] In the field of optical communications, optical fiber is used as a medium for information transmission, and its production quality and efficiency are directly related to the stability and development of information networks. The production process of optical fiber is complex and delicate, and the performance of the feeding system directly affects the uniformity, quality and overall production efficiency of the optical fiber coating. Traditional feeding methods often have many limitations, such as the inability to achieve flexible distributed feeding, the need to stop production and clean the entire line for coating replacement, resulting in low efficiency, and bubbles that are easily generated during coating transmission, affecting product quality. To solve these problems, this application focuses on an innovative feeding system for optical fiber production. In order to achieve efficient, flexible and accurate feeding, the specific composition, working principle, technical advantages and significant effects of the system in practical applications will be discussed in detail below to present a comprehensive and in-depth understanding.

[0023] See also Figure 1 to Figure 2 As shown, a feeding system for optical fiber production in a preferred embodiment of the present application supports distributed feeding without affecting centralized feeding, is compatible with coating tests, and can also avoid the presence of bubbles in the coating. It specifically includes a ton barrel 100, a buffer tank 200, a small material tank 700, a pipeline unit 300, a sensor 400 and a control unit 500. This feeding system is specially designed for optical fiber production. Its uniqueness lies in that it supports distributed feeding mode without affecting the continuity of centralized feeding, and integrates the compatibility of coating tests and automatic bubble removal functions.

[0024] The pipeline unit 300 includes a first pipeline 310, a second pipeline 320 and a third pipeline 330. The first pipeline 310 connects the ton barrel 100 and the buffer tank 200, the second pipeline 320 connects the buffer tank 200 and the small material tank 700, and the third pipeline 330 connects the small material tank 700 and the drawing tower. The pipeline unit 300 is designed into three parts: the first pipeline 310 is responsible for efficiently transporting the paint from the ton barrel 100 to the buffer tank 200, ensuring a stable supply of large quantities of paint; the second pipeline 320 connects the buffer tank 200 and the detachable small material tank 700, which not only realizes the transition buffering of the paint, but also provides convenience for the rapid replacement of the test paint; the third pipeline 330 seamlessly connects the small material tank 700 and the drawing tower, ensuring the accurate and continuous supply of paint on the production line. The first pipeline 310 , the second pipeline 320 , and the third pipeline 330 are respectively provided with a control valve 600 , and the control valve 600 is used to achieve precise regulation and emergency cutoff of flow.

[0025] Buffer tank 200 serves as the "water reservoir" of the system. When ton barrel 100 is replaced or maintained, buffer tank 200 can continue to provide a stable supply of paint to the production line, avoiding production interruption. Secondly, its internal structure design facilitates the natural floating and static removal of bubbles in the paint, significantly improving the paint quality and reducing optical fiber quality problems caused by bubbles. By adding buffer tank 200, the production interruption time caused by the replacement of ton barrel 100 is reduced, thereby improving the overall production efficiency.

[0026] The sensor 400 detects the status of the ton barrel 100, the buffer tank 200 and the small material tank 700, and transmits the relevant signal to the control unit 500. The sensor group 400 throughout the system monitors the key parameters such as the liquid level, pressure, temperature, etc. of the ton barrel 100, the buffer tank 200 and the small material tank 700 in real time, and transmits the data to the intelligent control unit 500 in real time. The control unit 500 is connected to each of the control valves 600 to adjust the status of the control valves 600. The control unit 500 automatically adjusts the opening and closing status of each control valve 600 based on the preset algorithm and real-time data, optimizes the paint flow and pressure, and predicts and responds to potential faults, so as to realize the intelligent management and efficient operation of the feeding system. The integrated application of the sensor 400 and the control unit 500 realizes the intelligent monitoring and automatic adjustment of the feeding system, reduces the need for manual intervention, and improves the stability and reliability of the system operation.

[0027] Among them, the small material tank 700 is detachably connected to the second pipeline 320 and the third pipeline 330. This design enhances the flexibility and testing capabilities of the system. Through simple and quick disassembly and installation, the operator can easily replace the small material tank 700 containing different formulas or test coatings. There is no need to interrupt the main production line, and the coating performance can be quickly verified and optimized, which accelerates the research and development cycle of new products.

[0028] In order to further improve the flexibility and efficiency of the optical fiber production feeding system, a plurality of buffer tanks 200 are included, each of which includes the corresponding first pipeline 310, each of which is connected to a plurality of small material tanks 700, and each of which includes the corresponding second pipeline 320. Specifically, a plurality of independent buffer tanks 200 are configured in the system, each of which is equipped with an exclusive first pipeline 310, which is directly connected to the ton barrel 100, ensuring the rapid and stable transmission of the coating from the ton barrel 100 to the buffer tank 200. More importantly, each buffer tank 200 can be connected to and serve multiple small material tanks 700 at the same time, and each small material tank 700 is connected to the buffer tank 200 through its exclusive second pipeline 320, forming a many-to-many feeding network. The flexible configuration of multiple buffer tanks 200 and multiple small material tanks 700 not only greatly enhances the feeding capacity of the system, but also significantly improves the flexibility and response speed of the production line. When a production line needs to change paint or perform maintenance, it only needs to switch to other small material tanks 700 that have been prepared with paint to achieve seamless connection without interrupting the operation of the entire production line. At the same time, the existence of multiple buffer tanks 200 also provides more space and possibilities for temporary storage and pretreatment of paint, further reducing bubbles in the paint and improving the quality of the paint.

[0029] In order to further optimize the degree of automation and coating utilization efficiency of the optical fiber production feeding system, the system specially introduces a ton barrel 100 placement rack design with an integrated lifting cylinder or spring, specifically including a ton barrel 100 placement rack, the ton barrel 100 is placed on the ton barrel 100 placement rack, the ton barrel 100 placement rack also includes a lifting cylinder, the ton barrel 100 is tilted by the lifting cylinder, the sensor 400 detects the weight of the ton barrel 100, and in a further technical solution, a spring is set on the ton barrel 100 placement rack, and the spring is set to lift the end of the ton barrel 100 away from the outlet upward as the coating in the ton barrel 100 decreases, so that the ton barrel 100 tilts toward its outlet, so that the coating in the ton barrel 100 is drained as much as possible. Specifically, the ton barrel 100 is placed on a special ton barrel 100 placement rack, which is equipped with a precision lifting cylinder. When the remaining paint in the ton barrel 100 needs to be emptied, the control unit 500 will start the lifting cylinder according to the real-time feedback of the sensor 400, so that it slowly and steadily pushes one end of the ton barrel 100 up, so that the ton barrel 100 as a whole tilts toward the outlet. This design cleverly uses the principles of physics to allow the paint to flow out of the ton barrel 100 more smoothly, reducing residue. In addition, a spring device is optionally added to the ton barrel 100 placement rack. The spring is cleverly installed below the end of the ton barrel 100 away from the outlet, and its elastic coefficient is accurately calculated to ensure that as the paint in the ton barrel 100 gradually decreases, the spring can automatically and appropriately lift this end of the ton barrel 100 upward. Through the lifting cylinder or spring, the dynamic tilt adjustment of the ton barrel 100 during the feeding process is achieved, ensuring that the paint can be almost completely emptied.

[0030] Specifically, the ton barrel 100 placement rack is arranged above the buffer tank 200, and the first pipeline is not pressurized. The ton barrel 100 placement rack is arranged directly above the buffer tank 200. This design not only optimizes the space utilization, but also creates conditions for the natural flow of the paint. On this basis, gravity is used as the motive force for the transmission of the paint in the first pipeline, and the traditional pressurization method is abandoned. Specifically, the ton barrel 100 is firmly placed on the placement rack, and its outlet is seamlessly connected with the first pipeline below. When it is necessary to feed the buffer tank 200, the paint naturally slides along the first pipeline under the action of gravity and finally flows into the buffer tank 200. In this process, no external pressure equipment is required to intervene, which not only simplifies the system structure, but also greatly reduces energy consumption and operating costs. The use of gravity to transmit paint not only ensures the stability and continuity of the paint flow, but also effectively avoids problems such as leakage, pollution or damage to the paint quality that may be caused by improper pressurization. In addition, gravity transmission also reduces the friction and impact of the paint in the pipeline, helps to protect the pipeline from wear and tear, and extends the service life of the system.

[0031] In order to improve the overall operational stability and safety of the optical fiber production and feeding system, an alarm unit is also included. The addition of this unit enables the system to quickly issue an alarm when an abnormality or potential fault is detected, reminding the operator to take corresponding measures in time, thereby effectively avoiding production interruptions or safety accidents. The alarm unit communicates with each key component in the system (such as the ton barrel 100 placement rack, buffer tank 200, small material tank 700, sensor 400, etc.) in real time to continuously monitor its operating status and parameters. Once any abnormality is found (such as insufficient paint, pipeline blockage, abnormal pressure, equipment failure, etc.), the alarm unit will be activated immediately, and the alarm information will be accurately conveyed to the operator through various methods such as sound and light alarms, SMS notifications, and email reminders. In addition, the alarm unit also has an intelligent analysis function. It can preliminarily determine the cause of the abnormality based on historical data and current status, and give corresponding processing suggestions to provide strong support for operators. The real-time monitoring and rapid response capabilities of the alarm unit can promptly discover and deal with potential safety hazards, effectively avoid the occurrence of safety accidents, and ensure the safety of the production environment. Through timely alarms and handling of abnormalities, the alarm unit can reduce the number and duration of production interruptions and improve the overall stability and reliability of the production line.

[0032] In order to improve the flexibility and efficiency of the feeding system, this design specifically introduces the fourth pipeline as an independent channel, directly connecting the inlet and outlet of the small material tank 700. Specifically, it also includes a fourth pipeline, which is an independent pipeline connecting the inlet and outlet of the small material tank 700. As a dedicated channel, the inner diameter, material and connection method of the fourth pipeline are designed to ensure the smoothness, stability and safety of the paint during the transmission process. When the system is in a specific working mode or needs to quickly adjust the feeding path according to production needs, the paint can be guided to the fourth pipeline through devices such as the control valve 600 door, so that the paint is directly transmitted to the next link without passing through the small material tank 700. The introduction of the fourth pipeline also increases the redundancy of the system, that is, when the main feeding path fails or needs maintenance, it can quickly switch to the fourth pipeline as a backup path to ensure the continuity and stability of production.

[0033] Please read further Figure 2, the buffer tank 200 is arranged obliquely above the small material tank 700, and the second pipeline is arranged obliquely. This layout design also takes into account the auxiliary effect of gravity. The buffer tank 200 is placed at a higher position, and the gravity difference is used to enable the paint to automatically flow to a lower place, which reduces the use of auxiliary equipment such as pumping, reduces energy consumption and extends the service life of the equipment. By utilizing the gravity difference to promote the natural flow of the paint, the frequency and intensity of use of auxiliary equipment such as pumping are reduced, thereby reducing energy consumption and improving the overall energy efficiency of the system. The layout method of placing the buffer tank 200 obliquely above the small material tank 700 makes the overall structure of the system compact and reasonable, optimizes space utilization, and saves production site occupation.

[0034] Specifically, the discharge port of the small material tank 700 is arranged at the lower part. Setting the discharge port at the lower part not only conforms to the physical law that fluid materials such as paint naturally sink due to gravity, but also significantly improves the efficiency and stability of feeding. Through this design, the paint can naturally flow out through the discharge port at the lower part after accumulating to a certain amount in the small material tank 700, without the need for additional auxiliary means such as pumping or vibration, thereby simplifying the operation process and reducing energy consumption. In addition, setting the discharge port at the lower part also helps to reduce the residual phenomenon of paint in the tank. Since the paint is affected by gravity in the tank, it tends to gather in a low place. Therefore, the discharge port is located at the lower part, which can more effectively empty the paint in the tank and avoid waste. At the same time, this also facilitates subsequent cleaning and maintenance work, reducing the difficulty and cost of cleaning.

[0035] Specifically, a degassing device is also included between the buffer tank 200 and the small material tank 700. This design is intended to further improve the quality and stability of the paint. The degassing device serves as a bridge connecting the two key components. It integrates efficient degassing technology inside, which can effectively remove bubbles or mixed air generated during the transmission of the paint. If these bubbles are not handled in time, they will not only affect the uniformity and adhesion of the paint, but may also have an adverse effect on the subsequent production process. The working principle of the degassing device is based on physical methods. By controlling pressure, temperature or introducing specific media, the bubbles in the paint are quickly gathered and discharged. The structure is compact and easy to operate. It can be seamlessly integrated into the existing feeding system without causing too much impact on the overall layout.

[0036] Specifically, the first pipeline 310 includes a plurality of access ports, each of which is connected to a ton barrel 100, and the buffer tank 200 is arranged on a vibration platform. By arranging a plurality of access ports thereon, simultaneous access and independent control of a plurality of ton barrels 100 are realized, and each access port is carefully designed with a sealing and quick connection mechanism to ensure a stable connection and leak-free transmission between the ton barrel 100 and the first pipeline 310. In addition, in order to further ensure the smooth flow and efficient use of the paint, the buffer tank 200 is cleverly placed on a vibration platform. The vibration platform serves as a support and auxiliary device for the buffer tank 200. By generating vibrations of a certain frequency and amplitude, it can effectively prevent the paint from being deposited, agglomerated or forming bubbles in the buffer tank 200. This vibration effect not only promotes the uniform mixing and flow of the paint, but also improves the transmission efficiency of the paint from the ton barrel 100 to the buffer tank 200, and reduces the risk of production interruption caused by blockage or poor flow.

[0037] As can be seen from the foregoing, this application provides an efficient, flexible and reliable feeding system for optical fiber production. The system realizes accurate feeding and flexible deployment of multiple optical fiber production lines through innovative modular design, and at the same time meets the production line's demand for rapid switching of multiple coatings in different test stages without the need to shut down the entire line, greatly improving production efficiency and flexibility. It consists of ton barrels, buffer tanks, small material tanks, pipeline units, sensors, control units and multiple optional enhanced components (such as ton barrel racks, lifting cylinders, alarm units, fourth pipelines, degassing devices, vibration platforms, etc.), forming a comprehensive feeding solution that integrates intelligent monitoring, precise control, efficient transmission and stable supply.

[0038] Specifically, this system realizes the initial feeding from the ton barrel to the buffer tank through the first pipeline. The setting of the buffer tank effectively balances the volatility of the paint supply and ensures the stability and continuity of the paint supply. The second pipeline accurately distributes the paint in the buffer tank to each small material tank to support the independent feeding needs of multiple production lines. The detachable design of the small material tank facilitates the rapid replacement of paint and meets the production line's testing needs for different paints. The third pipeline is responsible for transporting the paint in the small material tank to production equipment such as the drawing tower to ensure the smooth progress of the production process.

[0039] In addition, the system also integrates advanced sensors and control units, which can monitor the status information of the liquid level, weight, etc. of ton barrels, buffer tanks and small material tanks in real time, and automatically adjust the opening and closing status of each control valve accordingly to achieve intelligent supply and precise distribution of paint. This not only improves the utilization rate of the paint, but also reduces production failures caused by human operating errors. Through innovative measures such as adding degassing devices, optimizing pipeline design, and setting the buffer tank diagonally above the small material tank, the risk of bubbles generated during the transportation of the paint is effectively reduced, and the surface quality and consistency of optical fiber products are improved. At the same time, the feature of supporting multiple communication protocols enables this system to be easily integrated into various production environments, achieving seamless docking and interlocking control with equipment such as drawing towers, further enhancing the compatibility and scalability of the system.

[0040] The above is only a specific implementation of the present application, and any other improvements made based on the concept of the present application are deemed to be within the protection scope of the present application.
