Description

Technical Field

[0001] This utility model relates to the field of quartz optical fiber production and processing technology, specifically to a coating device for quartz optical fibers. Background Technology

[0002] Quartz optical fiber has become the core carrier of modern optical communication due to its low loss and high bandwidth characteristics. It is a fiber-shaped optical device made of high-purity quartz glass as the core material. It consists of three parts: core, cladding and coating. In actual processing, coating equipment is used to form a stable coating on the outer wall of the quartz optical fiber cladding. This improves the quartz optical fiber product's resistance to environmental interference and provides a foundation for subsequent processing and applications.

[0003] Current quartz fiber coating equipment often requires user assistance in positioning and forward conveying the product when coating the outer cladding of long quartz fibers. This makes it difficult for the equipment to achieve automated continuous coating processing and easily leads to problems such as spray position deviation and uneven coating surface, resulting in poor processing effect that no longer meets people's needs. Based on this, we propose a new type of quartz fiber coating equipment to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for quartz optical fibers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for quartz optical fibers, including a frame, and further comprising... The adjustable slide rails are respectively installed on both sides of one end of the frame. A second motor is installed at the bottom of the adjustable slide rail. The output end of the second motor is connected to a worm gear transmission assembly. The adjustable slide rail is internally connected to a lead screw that matches the worm gear transmission assembly. Sliding parts that match the lead screw are uniformly slidably connected on the adjustable slide rail. A PLC controller is embedded in the outer wall of the frame, a third motor is installed on one side of the sliding part, and a positioning drive roller is connected between adjacent third motors. The material bin is installed at the bottom of the machine frame. The top of the material bin is equipped with an arc-shaped top cover. Spray nozzles are installed on both sides inside the arc-shaped top cover. A corrosion-resistant pump connected to the spray nozzles is installed on the material bin. The top of the frame is threadedly connected to a guide seat, and the top of the guide seat is provided with an annular scraper.

[0006] Furthermore, a partition plate is provided at the middle position of the lead screw, and the outer walls of the lead screw at the top and bottom of the partition plate are provided with external thread layers in opposite directions.

[0007] Furthermore, two sliding members are provided, and adjacent sliding members are symmetrically distributed about the horizontal center line of the separator.

[0008] Furthermore, the inner wall of the sliding member is provided with an internal thread layer that matches the external thread layer.

[0009] Furthermore, the third motor and the sliding component are connected by screws to form a disassembly and assembly structure.

[0010] Furthermore, a threaded locking post is provided at the bottom of the guide seat, and a threaded connection is formed between the threaded locking post and the frame.

[0011] Furthermore, a first motor is installed at the top of the material bin, and the output end of the first motor is connected to a mixing shaft.

[0012] Furthermore, a sealing plate is provided between the first motor and the hopper, and a temperature sensor is installed at the bottom of the sealing plate.

[0013] Furthermore, a heating wire is installed at the bottom of the mixing shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The quartz optical fiber coating equipment optimizes its performance by incorporating a second motor. The PLC controller can start the second motor, which, combined with the transmission and self-locking properties of the worm gear drive assembly, ensures smooth rotation of the lead screw, preventing loosening. Furthermore, a separator is positioned in the middle of the lead screw, with oppositely oriented external threads on the top and bottom of the separator. The inner walls of the two sliding parts have matching internal threads, allowing the two symmetrically distributed sliding parts to move synchronously towards or away from each other. This alters the distance between the two positioning drive rollers, enabling them to coat the outer wall of the cladding material of the quartz optical fiber to be coated. Automated calibration and positioning ensure the product is centered in the processing position. Simultaneously, the third motor on the sliding component starts, driving the positioning drive roller to rotate and push the product forward automatically. This facilitates continuous coating processing and improves work efficiency. On the other hand, the product conveyed by the positioning drive roller enters the interior of the arc-shaped top cover. At this time, two corrosion-resistant pumps start, automatically pumping the coating material from the material box into the nozzle. The coating is then evenly applied to the outer wall of the product through symmetrically distributed nozzles. After completing one coating, the product continues to be conveyed forward and passes through the annular scraper inside the two guide seats to scrape off the excess material on the outer wall of the product, improving the coating effect on the outer wall and ensuring the uniformity of the coating surface.

Based on the partition plate 1 set at the middle position of the lead screw 3, the lead screw 3 at the top and bottom of the partition plate 1 is provided with external thread layers in opposite directions. The inner sidewalls of the two sliding parts 2 are respectively provided with internal thread layers that match the external thread layers. This can drive the two vertically symmetrically distributed sliding parts 2 to move synchronously towards or away from each other. This can change the distance between the two positioning drive rollers 15, so that they can automatically calibrate and position the outer wall of the cladding of the quartz optical fiber raw material to be coated, ensuring that it is in the center processing position. At the same time, the third motor 14 on the sliding part 2 starts, driving the positioning drive roller 15 to rotate, which can push the product forward automatically. This facilitates the continuous coating process of the product and improves work efficiency. Material box 22 is installed at the bottom of the machine frame 10. The top of the material box 22 is provided with an arc-shaped top cover 6. Both sides of the arc-shaped top cover 6 are provided with nozzles 7.

On the other hand, the heating wire 16 installed at the bottom of the mixing shaft 19 is energized to generate heat, which heats the coating material. Combined with the temperature monitoring function of the temperature sensor 18 installed at the bottom of the sealing plate 17, the coating material can be effectively heated and temperature controlled, avoiding the problem of condensation of the coating material inside the material box 22, improving the coating effect of the quartz optical fiber, and also avoiding the problem of clogging of the spraying equipment.

This allows the two symmetrically distributed sliding parts 2 to move synchronously towards or away from each other. This changes the distance between the two positioning drive rollers 15, enabling automated calibration and positioning of the outer cladding wall of the quartz optical fiber raw material to be coated, ensuring it is in the center processing position. Simultaneously, the third motor 14 on the sliding part 2 starts, driving the positioning drive rollers 15 to rotate, which can automatically convey the product forward. This facilitates continuous coating processing and improves work efficiency. Then, the product conveyed by the positioning drive rollers 15 enters the arc-shaped top...
