Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber production, specifically a coating device for optical fiber production. Background Technology

[0002] In the optical fiber production process, different types of coating materials need to be selected according to different uses, environments, and application fields. For example, in applications requiring rapid curing, ease of production, and low cost, acrylic resin coatings can be selected; while in applications requiring special properties such as high temperature resistance and radiation resistance, polyimide or metal coatings can be selected to meet specific application requirements. For example, the prior art patent document with publication number CN211035709U provides a resin coating device for optical fiber production. This device, by setting up a mounting frame, a first connecting block, a second connecting block, a motor, a first rotating shaft, a first drum, a third connecting block, a fourth connecting block, a second rotating shaft, and a second drum, can realize rapid pulling of optical fibers, facilitating rapid application of resin to the optical fibers.

[0003] However, when the device winds up the optical fiber using a rotating first drum, the optical fiber ends up on the outer edge of the drum. This obviously limits the drum's ability to collect the optical fiber and has significant drawbacks. To address this, we propose a coating device for optical fiber production. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a coating device for optical fiber production, including an operating table 1, a first roll 13 and a second roll 14 rotatably mounted on the upper end of the operating table 1, a heating sleeve 2 slidably mounted on the upper end of the operating table 1, a guide sleeve 21 fixedly mounted on the front end of the heating sleeve 2, a movable plate 24 fixedly mounted on the lower end of the heating sleeve 2, a rotating disk 25 rotatably mounted on the upper end of the operating table 1, an eccentric slider 251 slidably connected to the movable plate 24 fixedly mounted on the outer periphery of the upper end of the rotating disk 25, a drive motor 15 and a spray frame 31 fixedly mounted on the upper end of the operating table 1, the output shaft of the drive motor 15 being interconnected with the first roll 13 and the rotating disk 25 via a transmission belt, and the spray frame 31 being disposed between the heating sleeve 2 and the guide sleeve 21.

[0025] Working principle: When in use, the optical fiber is pulled outward from the outer periphery of the second drum 14 and inserted into the guide sleeve 21, the spray frame 31 and the heating sleeve 2 in sequence. Finally, the optical fiber is fixedly installed on the outer periphery of the first drum 13.

[0026] When the drive motor 15 is started, the first drum 13 and the rotating disk 25 can be rotated through its output shaft and transmission belt. Firstly, the rotating first drum 13 can wind up the optical fiber. Secondly, since the heating sleeve 2 is slidably connected to the operating table 1, the movement direction of the heating sleeve 2 can be restricted, so that the rotating disk 25 can drive the heating sleeve 2 to reciprocate in front of the first drum 13 through the sliding connection between the eccentric slider 251 and the movable plate 24, thereby evenly winding the optical fiber around the first drum 13. A guide sleeve 21 fixedly connected to the heating sleeve 2 is provided in front of the spray frame 31, so that the optical fiber can enter the spray frame 31 in a vertical direction.

[0027] During the optical fiber winding process, the spray frame 31 and the heating sleeve 2 are activated. The spray frame 31 can uniformly coat the surface of the optical fiber, and the heating sleeve 2 can heat and cure the resin around the optical fiber.

[0028] As a further description of the above technical solution: A bracket 17 is fixedly installed on the upper end of the operating table 1, and a spray frame 31 is fixedly installed on the upper end of the bracket 17. A limiting rotation cavity 172 is opened on the upper end of the bracket 17, and a rotating disk 25 is rotatably installed in the limiting rotation cavity 172. A limiting slide groove 241 is opened on the lower end of the movable plate 24, and an eccentric slider 251 is slidably installed in the limiting slide groove 241. A limiting slide rail 171 is fixedly installed on the upper end of the bracket 17, and a limiting slide cavity 22 is opened on the outer side of the heating sleeve 2, which is slidably connected to the limiting slide rail 171. A limiting rotating seat 18 is fixedly installed on the upper end of the operating table 1, and a worm gear 26 is rotatably installed in the limiting rotating seat 18. The output shaft of the drive motor 15 is rotatably connected to the worm gear 26 through a transmission belt. A worm wheel 252 is fixedly installed on the lower end of the rotating disk 25, and the worm gear 26 and the worm wheel 252 are meshed with each other.

[0029] Specifically, the rotational connection between the limiting rotational cavity 172 and the rotating disk 25 can restrict the direction of movement of the rotating disk 25;

[0030] By sliding between the limiting slide rail 171 and the limiting slide cavity 22, the movement direction of the heating sleeve 2 can be restricted at the upper end of the bracket 17, so that the rotating disk 25 can drive the heating sleeve 2 to reciprocate through the sliding connection between the limiting slide groove 241 and the eccentric slider 251.

[0031] The limiting rotating seat 18 can restrict the movement direction of the worm 26. Through the rotational connection between the worm 26 and the output shaft of the drive motor 15 and the threaded connection between the worm wheel 252 and the worm 26, the drive motor 15 can drive the rotating disk 25 to rotate.

[0032] As a further description of the above technical solution: The inner cavity of the spray frame 31 is provided with a feeding chamber 32 and a collecting chamber 33 on the upper and lower sides respectively. A nozzle 34 is fixedly installed at the upper end of the collecting chamber 33, and the nozzle 34 is connected to the feeding chamber 32. A storage tank 3 is fixedly installed at the upper end of the operating table 1. A feeding pipe 36 and a return pipe 37 are fixedly installed at the outer end of the storage tank 3. The feeding pipe 36 is connected to the feeding chamber 32, and the return pipe 37 is connected to the bottom of the collecting chamber 33. A conveying pump 35 connected to the feeding pipe 36 is fixedly installed inside the storage tank 3. A filling hole 38 is opened at the upper end of the storage tank 3.

[0033] Specifically, when it is necessary to coat the surface of the optical fiber with resin through the spray frame 31, the delivery pump 35 is started, and the resin inside the storage tank 3 is transported to the feeding chamber 32 through the feed pipe 36. Then, it is sprayed vertically into the collection chamber 33 through the nozzle 34 to achieve the effect of coating the optical fiber inside the collection chamber 33.

[0034] The resin that falls into the collection chamber 33 can be recycled to the storage tank 3 through the return pipe 37, which is convenient for subsequent coating operations. The injection hole 38 is provided so that the resin can be injected into the storage tank 3.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
