Description

Technical Field

[0001] This utility model relates to the field of optical fiber manufacturing technology, and in particular to an optical fiber transmission mechanism. Background Technology

[0002] In the field of optical fiber manufacturing, the optical fiber transport mechanism is a core hub connecting key processes such as preform drawing, coating, plastic coating, and take-up. Its operating status directly determines the continuity of optical fiber production and the quality of the final product. This mechanism achieves high-speed and stable transport of optical fiber in each process stage through the coordinated transmission of components such as guide wheels and traction wheels, ensuring that the optical fiber completes subsequent processing at a preset speed and tension. The cleanliness of the optical fiber product surface is of paramount importance.

[0003] In actual production scenarios, the optical fiber transmission process faces multiple risks of foreign object contamination. On the one hand, dust, suspended particulate matter, and other impurities are unavoidable in the production workshop environment. These foreign objects are carried by airflow and adsorbed onto the surface of the optical fiber when it moves at high speed. On the other hand, during the long-term contact between production equipment and optical fiber, tiny abrasive particles or stains are generated. These contaminants are easily detached and adhere to the surface of the optical fiber. These foreign objects, such as dirt and dust, adhering to the surface of the optical fiber can have multiple negative impacts on optical fiber production: First, foreign objects can damage the integrity of the optical fiber surface; second, the presence of contaminants can hinder the tight bonding between the coating layer and the optical fiber surface, leading to defects such as coating peeling and cracking, which cannot effectively play a protective role and reduce the bending resistance and environmental corrosion resistance of the optical fiber; third, hard foreign objects may scratch the surface of the optical fiber during transportation, forming fine scratches, further aggravating transmission loss, and even increasing the risk of breakage during subsequent use of the optical fiber.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: In order to remove impurities adhering to the surface of the optical fiber during the optical fiber delivery process, this embodiment provides a new optical fiber delivery mechanism 2.

[0021] like Figure 1 , Figure 2 As shown, the conveying mechanism 2 includes a housing 3, a guide wheel 4, and a gas dispersion structure 6, with both the guide wheel 4 and the gas dispersion structure 6 disposed inside the housing 3.

[0022] like Figure 3 , Figure 4 , Figure 5As shown, specifically, the housing 3 includes a cylindrical body 32 and a cover plate 31 detachably disposed at the opening end of the cylindrical body 32. Two inlet / outlet holes 33 are symmetrically arranged on the side wall of the cylindrical body 32. The guide wheel 4 is located in the middle of the cylindrical body 32, and the central axis of the guide wheel 4 is disposed through the hole 36 of the cylindrical body 32. At the same time, the end of the central axis of the guide wheel 4 is inserted into the bearing seat 35. In addition, the central axis of the guide wheel 4 can be connected to the motor for power as needed. After the mechanism is installed on the conveying route, the optical fiber enters the housing 3 through one inlet / outlet hole 33, then contacts the guide wheel 4, and finally exits the housing 3 through the other inlet / outlet hole 33. In order to limit the position of the optical fiber relative to the guide wheel 4, the guide wheel 4 is provided with an annular guide groove 41. The cross-section of the annular guide groove 41 is set with a V-shaped structure, and the bottom of the cross-section is chamfered. The optical fiber supported on the guide wheel 4 is adapted to the chamfer.

[0023] like Figure 7 As shown, the gas dispersion structure 6 includes an annular pipe 62 and multiple nozzles 61 evenly and interconnectedly mounted on the annular pipe 62. The annular pipe 62 is fitted to the end of the cylinder 32, and the inlet end of the annular pipe 62 is connected to the output end of the blower 1 through the gas delivery pipe 11 and the air filter. When the blower 1 is working, it draws gas into the housing 3, increasing the pressure inside the housing 3. Under the action of the internal and external pressure difference, the gas inside the housing 3 is discharged from the inlet and outlet holes 33, that is, there are two airflows rushing out of the housing 3, blocking external impurities from entering, and at the same time blowing away dust and other impurities on the surface of the optical fiber, realizing the initial cleaning of the optical fiber.

[0024] like Figure 4 As shown, with the bearing housing 35 stably installed, in order to ensure the housing 3 is placed stably, two brackets 34 are detachably provided on the back side of the housing 3. The brackets 34 are designed as L-shaped structures, and the horizontal sections of the brackets 34 are connected to the bearing housing 35 by bolts, thereby stably supporting the device under the action of the bearing housing 35.

[0025] like Figure 7 As shown, in order to stably install the annular tube 62 inside the housing 3, an externally threaded tube 63 is provided at the top of the annular tube 62, and an internally threaded sleeve 64 is threaded onto the externally threaded tube 63. When assembling the annular tube 62 and the housing 3, the externally threaded tube 63 is provided through the hole at the top of the cylinder 32, and then the internally threaded sleeve 64 is fitted onto the externally threaded tube 63, while the bottom of the internally threaded sleeve 64 is positioned to press against the cylinder 32.

[0026] like Figure 5 , Figure 6As shown, to further clean the surface of the optical fiber, a first receiving chamber 42 is provided below the guide wheel 4. The main body of the first receiving chamber 42 is an arc-shaped plate, and triangular plates are provided at both ends of the arc-shaped plate. The arc-shaped plate is positioned near the arc-shaped surface of the guide wheel 4, and the triangular plates extend into the annular guide groove 41, with a gap between the triangular plates and the side of the annular guide groove 41. A first cleaning cotton 43 is placed in the space formed by the first receiving chamber 42 and the guide wheel 4. Therefore, when the optical fiber is attached to the guide wheel 4, the first receiving chamber 42 is stationary on the housing 3. The first receiving chamber 42 compresses the first cleaning cotton 43 into the annular guide groove 41, and at the same time, the first cleaning cotton 43 contacts the optical fiber, thereby achieving secondary cleaning of the optical fiber.

[0027] like Figure 6 As shown, to ensure stable installation of the first receiving chamber 42 relative to the cover plate 31, a first support rod 45 is fixedly installed below the first receiving chamber 42. The first support rod 45 passes through the first support plate 46, and a nut is threaded onto one end of the first support rod 45 protruding from the first support plate 46. The first support plate 46 is vertically installed on the cover plate 31. A first spring 44, fitted onto the first support rod 45, contacts both ends of the first receiving chamber 42 and the first support plate 46, respectively, and is in a compressed state. With the cooperation of the first support rod 45 and the first support plate 46, the first receiving chamber 42 is stably installed on the side of the cover plate 31, and when the first spring 44 recovers its deformation, the first receiving chamber 42 always tends to move closer to the guide wheel 4.

[0028] like Figure 2 , Figure 8 As shown, in order to keep the optical fiber taut during transmission, a pressing device 5 is provided inside the housing 3. The pressing device 5 includes an arc-shaped plate 51, two pressing rollers 52, and two second receiving chambers 53. The two pressing rollers 52 are rotatably mounted on the support shafts 513 at both ends of the arc-shaped plate 51. The two second receiving chambers 53 are respectively positioned above the two pressing rollers 52, and a second cleaning cotton 531 is placed in the space formed by the second receiving chambers 53 and the pressing rollers 52. During assembly, the arc-shaped plate 51 is adjustablely mounted on the cylinder 32 and is positioned above the guide rollers 4. At the same time, the pressing rollers 52 are distributed on both sides of the guide rollers 4. Therefore, under the action of the two pressing rollers 52, the optical fiber contacts the guide rollers 4 in an inverted "Ω" shape, thereby controlling the optical fiber to be taut. At the same time, the second cleaning cotton 531 contacts the optical fiber and cleans the parts that the first cleaning cotton 43 cannot wipe, thereby effectively removing foreign matter adhering to the surface of the optical fiber.

[0029] like Figure 9As shown, to achieve the adjustable function of the arc plate 51, two ear plates are fixedly installed on the top of the arc plate 51. One ear plate has a through hole 511, and the other ear plate has a threaded hole 512. A guide rod 515 is inserted through the through hole 511, and a threaded post 516 is threaded through the threaded hole 512. The tops of both the guide rod 515 and the threaded post 516 are inserted through the cylinder 32, and a connecting arc plate 514 is connected to the tops of both the guide rod 515 and the threaded post 516. The threaded post 516 is rotatably connected to the connecting arc plate 514. The connecting arc plate 514 is fitted against the outer surface of the cylinder 32. Therefore, with the cooperation of the connecting arc plate 514, the guide rod 515, and the threaded post 516, the arc plate 51 is stably installed inside the cylinder 32. When it is necessary to adjust the height of the arc plate 51 and thus adjust the position of the pressure roller 52, the threaded post 516 can be rotated to control the raising and lowering of the arc plate 51.

[0030] like Figure 10 As shown, to limit the position of the optical fiber and the pressure roller 52, a recessed groove 521 is provided on the outer wall of the pressure roller 52, and the recessed groove 521 and the annular guide groove 41 are located on the same plane. Therefore, the optical fiber passes through the recessed groove 521. To form a space for storing the cleaning cotton, a protrusion is provided at the end of the second receiving chamber 53. The protrusion of the second receiving chamber 53 extends into the recessed groove 521, and the protrusion does not contact the side of the recessed groove 521. Therefore, a space for storing the second cleaning cotton 531 is formed between the second receiving chamber 53 and the pressure roller 52.

[0031] like Figure 10 As shown, in order to ensure the stable installation of the second receiving chamber 53, a second support rod 533 is fixedly installed above the second receiving chamber 53. The second support rod 533 passes through the second support plate 532, and a nut is fitted on the part of the second support rod 533 that protrudes from the second support plate 532. Meanwhile, the second support plate 532 is vertically installed on the cover plate 31. In addition, the upper and lower ends of the second spring 534 fitted on the second support rod 533 are in contact with the second support plate 532 and the second receiving chamber 53, respectively.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any related changes, modifications or additions made without departing from the concept of the present utility model should be included within the protection scope of the present utility model.
