Description

Technical Field

[0001] The present invention relates to the technical field of optical cable production and processing, and particularly to a cleaning device for an optical fiber guide wheel. Background Art

[0002] In the optical cable production process, the sheathing process is responsible for binding multiple optical fibers in a sleeve. Multiple colored optical fibers are sequentially and synchronously released from an optical fiber pay-off stand. Each optical fiber pay-off stand station is equipped with a set of dancer wheels for dynamically adjusting the tension and a set of idler wheels. Each set of guide wheels consists of 2 to 3 single optical fiber guide wheels arranged coaxially. The optical fiber pay-off path needs to pass through each set of guide wheels. That is, each fiber pay-off station needs to pass through at least 5 guide wheels. Taking a conventional 12-core (station) as an example, each sleeve of optical fibers needs to pass through at least 60 guide wheels. According to the requirements of the optical cable product, the guide wheels on the optical fiber pay-off stand station need to be cleaned regularly. Therefore, the grooves of the guide wheels need to be cleaned in each shift to ensure that the path through which the optical fiber is wound meets the production environment requirements of being clean, free of impurities, and having no foreign objects on the surface.

[0003] In the actual production process, most rely on manual cleaning of the guide wheel grooves. Due to the low efficiency of manual cleaning operations, it is impossible to ensure the progress on time and in quantity, thus affecting the production rhythm of the entire process. At the same time, there are also problems in the actual implementation of manual cleaning of the guide wheels, such as inconsistent cleaning standards and cleaning dead corners. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a cleaning device for an optical fiber guide wheel to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is:

It includes a telescopic mechanism, a rotating mechanism, a driving rotation mechanism, and a cleaning component. The telescopic mechanism is fixed on the side of the optical fiber pay-off stand station, and its telescopic direction is parallel to the axial direction of the dancer wheel and the idler wheel.

[0012] Preferably, the transmission component is a first transmission wheel, a second transmission wheel and a transmission belt. The output end of the driving motor is connected to the first transmission wheel. Both ends of the roller shaft of the rotating roller are rotatably connected to the rotating roller bracket through bearings. One end of the roller shaft of the rotating roller on the same side as the output end of the driving motor penetrates through the rotating roller bracket and is connected to the second transmission wheel. The transmission belt is wound between the first transmission wheel and the second transmission wheel. The driving motor drives the first transmission wheel to rotate and drives the second transmission wheel to drive the rotating roller to rotate through the transmission belt.

The cleaning device is arranged at each fiber optic wire pay-off rack station, so that the dancing wheels or the fixed wheels at multiple fiber optic wire direction stations can be cleaned simultaneously, thereby improving the cleaning efficiency.

[0026] The technical solutions of the present invention will be clearly and completely described below through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0027] See Figures 1 to 6 As shown, a fiber optic guide wheel cleaning device is arranged at the position between the dancing wheel 1 and the fixed wheel 2 at the fiber optic pay-off rack station for directional cleaning according to cleaning requirements. This cleaning device includes a telescopic mechanism, a rotating mechanism, a driving rotation mechanism and a cleaning component. The telescopic mechanism is fixed on the side of the fiber optic pay-off rack station and its telescopic direction is parallel to the axial direction of the dancing wheel 1 and the fixed wheel 2. The rotating mechanism is fixedly connected to the output end of the telescopic mechanism through a connecting seat 3. The output end of the rotating mechanism is fixedly connected with a driving rotation mechanism so that the driving rotation mechanism rotates to contact the circumferential outer surface of the dancing wheel 1 or the fixed wheel 2. The cleaning component is fixedly connected to the driving rotation mechanism through an elastic fastening bracket 4 to rotate with the driving rotation component and embed into the groove 5 on the circumferential outer surface of the dancing wheel 1 or the fixed wheel 2.

[0028] The above-mentioned telescopic mechanism includes a telescopic cylinder 6 and a telescopic rod 7. The telescopic cylinder 6 is vertically arranged on the side of the optical fiber pay-off rack station. The telescopic rod 7 is drivingly connected to the telescopic cylinder 6 so that its telescopic direction is arranged parallel to the axial directions of the dancer roller 1 and the fixed pulley 2. A connecting seat 3 is fixed to the end of the telescopic rod 7 that is not connected to the telescopic cylinder 6. In order to ensure that the rotating mechanism, the driving and rotating mechanism, and the cleaning component are accurately moved into place and are in the same plane as the dancer roller 1 and the fixed pulley 2, a position sensor (not shown in the figure) is hereby provided at the end of the telescopic rod 7 where the connecting seat 3 is fixed.

[0029] The above-mentioned rotating mechanism includes a rotating base 8, a rotating cylinder 9, and a rotating disk 10. The rotating base 8 is arranged on the connecting seat 3 and a rotating cylinder 9 is built therein. The output end of the rotating cylinder 9 is connected to the center of one side surface of the rotating disk 10. A driving and rotating mechanism is connected to an arbitrary position on the other side surface of the rotating disk 10 so that the rotating cylinder 9 controls the driving and rotating mechanism to rotate and contact between the dancer roller 1 and the fixed pulley 2. Similarly, in order to ensure that the driving and rotating mechanism can be accurately rotated into place to fit and contact with the circumferential outer surface of the dancer roller 1 or the fixed pulley 2, a position sensor (not shown in the figure) is hereby provided at the connection of the rotating disk 10 and the driving and rotating mechanism.

[0030] The above-mentioned driving and rotating mechanism includes a motor base 11, a rotating roller bracket 12, a driving motor 13, a transmission component, and a rotating roller 14. One end of the motor base 11 is fixedly connected to the rotating disk 10, and the other end is fixedly connected to the rotating roller bracket 12. The driving motor 13 is fixed on the motor base 11. The rotating roller 14 is rotatably arranged along the axial direction of the dancer roller 1 or the fixed pulley 2, and its circumferential outer surface is a friction contact surface. The output end of the driving motor 13 is drivingly connected to the rotating roller 14 through the transmission component. In this embodiment, the transmission component adopts a first transmission wheel 15, a second transmission wheel 16, and a transmission belt 17. The output end of the driving motor 13 is connected to the first transmission wheel 15. Both ends of the roller shaft of the rotating roller 14 are rotatably connected to the rotating roller bracket 12 through bearings. One end of the roller shaft of the rotating roller 14 on the same side as the output end of the driving motor 13 penetrates through the rotating roller bracket 12 and is connected to the second transmission wheel 16. A transmission belt 17 is wound between the first transmission wheel 15 and the second transmission wheel 16. The driving motor 13 drives the first transmission wheel 15 to rotate and drives the second transmission wheel 16 to drive the rotating roller 14 to rotate through the transmission belt 17. Because the friction contact surface of the rotating roller 14 contacts the circumferential outer surface of the dancer roller 1 or the fixed pulley 2, the dancer roller 1 or the fixed pulley 2 can rotate together with the rotating roller 14 under the action of friction force, so that the cleaning component can comprehensively clean the grooves 5 on the dancer roller 1 or the fixed pulley 2.

[0031] The elastic fastening bracket 4 is in a zigzag shape. One end of the elastic fastening bracket 4 is rotatably connected to the side of the rotating roller 14 bracket away from the transmission component, and the rotation direction of the elastic fastening bracket 4 is the same as that of the rotating mechanism. The other end of the elastic fastening bracket 4 extends away from the rotating roller 14 and is provided with a cleaning component, so that the cleaning component corresponds to the friction contact surface position of the rotating roller 14. By rotatably connecting the elastic fastening bracket 4 with the rotating roller bracket 12, the cleaning component can be adaptively adjusted according to the positions of the dancing wheel 1 and the fixed wheel 2. In this embodiment, the cleaning component is a cleaning wipe 18, and serrated structures 19 are respectively provided on the upper and lower side surfaces of the cleaning wipe 18 to correspond to the grooves 5 on the outer circumferential surface of the dancing wheel 1 or the fixed wheel 2.

[0032] In addition, a fitting and holding component is provided between the side surfaces of the elastic fastening bracket 4 and the rotating roller bracket 12 to force the cleaning component to maintain an embedded state. The fitting and holding component includes a fixed column 20, a rotating column 21, and a tension spring (not shown in the figure). Fixed columns 20 are respectively and vertically provided on the upper and lower sides of the side surface of the rotating roller bracket 12 at the connection position of the elastic fastening bracket 4. A rotating column 21 is vertically provided at a position on the side surface of the elastic fastening bracket 4 facing away from the rotating roller bracket 12 and close to the connection position with the rotating roller bracket 12. Tension springs are respectively provided between the two fixed columns 20 and the rotating column 21 to form a triangular stable structure, so that after the cleaning wipe 18 is embedded in the groove 5 on the dancing wheel 1 or the fixed wheel 2, it can maintain a constant pressure and fit with the groove surface of the groove 5 under the action of the tension spring.

[0033] The working process of this device is as follows:

[0034] When the dancing wheel 1 or the fixed wheel 2 in the optical fiber pay-off frame station needs to be cleaned, the telescopic cylinder 6 is started, and under the cooperation of the position sensor, the telescopic rod 7 is driven to extend to a specified position, that is, to be in the same plane as the dancing wheel 1 and the fixed wheel 2, so that the subsequent rotating roller 14 can contact the outer circumferential surface of the dancing wheel 1 or the fixed wheel 2, and the cleaning wipe 18 can be embedded in the groove 5 on the outer circumferential surface of the dancing wheel 1 or the fixed wheel 2.

[0035] Thereafter, the rotating cylinder 9 is started to make the rotating disk 10 rotate towards the dancing wheel 1 or the fixed wheel 2 until the outer circumferential surface of the rotating roller 14 contacts the outer circumferential surface of the dancing wheel 1 or the fixed wheel 2. At this time, the serrated structure 19 on the cleaning wipe 18 is also embedded in the groove 5 on the outer circumferential surface of the dancing wheel 1 or the fixed wheel 2, and maintains a constant pressure and fits with the groove surface of the groove 5 under the action of the tension spring.

[0036] Subsequently, the drive motor 13 starts and drives the rotating roller 14 to rotate through the combined transmission of the first driving wheel 15, the second driving wheel 16 and the transmission belt 17. Since the outer circumferential surface of the rotating roller 14 is a friction contact surface that fits the outer circumferential surface of the dancing wheel 1 or the fixed wheel 2, the dancing wheel 1 or the fixed wheel 2 can rotate together with the rotating roller 14 under the action of friction, so that the cleaning block 18 can comprehensively clean the grooves 5 on the outer circumferential surface of the dancing wheel 1 or the fixed wheel 2. Since each group of dancing wheels 1 or fixed wheels 2 contains multiple guide wheel pieces, the cleaning block 18 can clean multiple guide wheel pieces simultaneously, and the overall cleaning efficiency is significantly improved. The cleaning time can be selected during the gap of replacing the production materials at the optical fiber pay-off frame station, without occupying separate cleaning time, which can improve the production rhythm and the unit output efficiency.

[0037] This device is also loaded with a control system to enable the device to have an automatic cleaning mode and a manual cleaning mode. In the automatic cleaning mode, the whole group can be cleaned, that is, the fixed wheel is cleaned first and then the dancing wheel is cleaned in sequence, or the fixed wheel or the dancing wheel can be cleaned separately. In the manual cleaning mode, it can be controlled to clean only the fixed wheel or the dancing wheel. During cleaning, the control system can adjust parameters such as cleaning time, frequency, and cleaning action mode at any time to meet different cleaning requirements.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
