Description

Technical Field

[0001] This utility model belongs to the field of optical fiber processing equipment technology, specifically relating to a guide wheel fixing device for improving the stability of optical fiber cabling. Background Technology

[0002] In the optical fiber manufacturing industry, the take-up stage of the optical fiber tension screening machine, coloring machine, and drawing machine plays a decisive role in the quality of the finished optical fiber. Currently, the technical defects of the take-up and winding reels are quite prominent in the industry: First, the winding reels have poor operational stability and are prone to shaking during operation, resulting in defects such as wire compression and skipping in the optical fiber. This is especially true when increasing the production line speed or producing small-diameter G.657 optical fiber (which has a smaller take-up tension setting), where the winding can easily form a stepped shape, seriously affecting the regularity of the optical fiber and product quality. Second, the existing fixed brackets, due to their slender structural design, lack sufficient mechanical strength. When the equipment is in high-speed take-up mode, the bracket vibration is significantly aggravated, which not only interferes with the normal production process but also poses a safety hazard to the equipment. Third, during the movement of the optical fiber in the long groove of the take-up winding device, it is easy to come into contact with and rub against the device components, resulting in scratches on the optical fiber surface and significantly reducing the yield of finished optical fiber products.

[0003] Under actual production conditions, the weight of a full reel of optical fiber at the take-up end is approximately 5 kg, the production line speed is 2500 m / min to 3000 m / min, the actual take-up speed is 5000 rpm to 6000 rpm, and the vibration value at the take-up end needs to be controlled within 5 mm. 2 Within a range of / s, existing technologies are insufficient to meet the aforementioned stringent performance requirements, necessitating breakthroughs through technological innovation.

[0004] Therefore, a guide wheel fixing device for improving the stability of optical fiber cabling is proposed. Summary of the Invention

[0005] This invention provides a guide wheel fixing device to improve the stability of optical fiber cabling, with the aim of solving the problems mentioned above.

The cabling wheel assembly includes: a cabling wheel fixing shaft that rotates through the outer wall of the fixed plate; a small shaft embedded at one end of the cabling wheel fixing shaft; a cabling wheel disposed on the outer wall of the small shaft; and a pressure wheel assembly disposed on the fixed plate. The pressure wheel assembly includes: a support rod disposed on the outer wall of the fixed plate; a pressure wheel fixing plate disposed on the outer wall of the support rod; a one-way bearing disposed on the inner wall of the pressure wheel fixing plate; a pressure wheel disposed on the inner wall of the one-way bearing; a cylinder fixing bracket disposed on the outer wall of the fixed plate near the top of the cabling wheel; an externally threaded cylinder disposed on the outer wall of the cylinder fixing bracket; a spherical bearing that rotates on the outer wall of the pressure wheel fixing plate; and a self-aligning connector disposed between the externally threaded cylinder and the spherical bearing.

[0007] Furthermore, a U-shaped slot is provided on one outer wall of the support plate to allow the fixing plate to move up and down.

[0008] Furthermore, a clamping ring is fixedly connected to one end of the fixed shaft near the support plate by bolts, and a positioning ring is provided on the outer side wall of the fixed shaft near the fixed plate, with the positioning ring and the fixed plate fitting together.

[0009] Furthermore, a groove is provided on one side of the outer wall of the fixing plate near the fixing shaft, and an adjustable handle screw is embedded on the top of the fixing plate near the groove. A screw hole is provided at the bottom of the groove to be screwed into the adjustable handle screw.

[0010] Furthermore, the cable guide assembly also includes a flange bearing located between the small shaft and the cable guide, and a spacer is provided on the outer side wall of the cable guide fixed shaft, the spacer being fixedly connected to the inner ring of the flange bearing.

[0011] Furthermore, the pressure roller assembly also includes a flange bearing two disposed between the support rod and the pressure roller fixing plate, and a spacer two is provided on the outer side wall of the support rod. The spacer two is fixedly connected to the inner ring of the flange bearing two, and an outer shaft clip passes through the outer side wall of the support rod near the flange bearing two.

[0012] Furthermore, the air inlet end of the external threaded cylinder is provided with a quick-connect fitting, one end of which is connected to an external air pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model has the following effects:

[0015] 1. Excellent scratch resistance: By using a special soft material on the surface and a shape-matched pressure wheel, combined with an optimized cable routing structure design, direct hard contact between the optical fiber and the device components during the cable take-up process is effectively avoided, thus solving the problem of scratches on the optical fiber surface from the root and significantly improving the qualification rate of finished optical fiber products.

[0016] 2. Significant vibration reduction effect: Through optimized structural design of core components such as the support plate and fixed shaft, and the adoption of scientific and reasonable component connection methods, the vibration amplitude of the cable guide wheel fixing bracket is significantly reduced. Actual testing has verified that, under full fiber optic coil and high-speed operation, the device vibration value can be stably controlled within the specified standard (less than 5mm). 2 Within a range of / s, it effectively ensures the stable operation of the equipment.

[0017] 3. Improved cable routing accuracy: The innovative design of the cable routing wheel assembly structure and its installation and adjustment method effectively reduces the sway of the cable routing wheel on the small shaft, ensuring tight and neat fiber routing, avoiding defects such as wire compression, jumpers, and steps, and significantly improving the quality and production efficiency of fiber optic cable take-up.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Reference Figure 1-3 This utility model embodiment proposes a guide wheel fixing device to improve the stability of optical fiber cabling. It is composed of multiple functional components. A support plate 1 serves as the basic load-bearing component, securely mounted on the equipment frame. A U-shaped slot is formed on its surface for connecting a fixed shaft 2. This U-shaped slot design allows the fixed shaft 2 to move vertically within the plane of the support plate 1, facilitating flexible adjustment of the installation height according to different production needs. Once the position of the fixed shaft 2 is determined, a bolt and a clamping ring 3 are used to apply a tightening force, firmly locking the fixed shaft 2 and ensuring the stability of the installation position.

[0026] The fixed plate 4 is sleeved on the fixed shaft 2 and has dual adjustment functions of forward and backward movement and left and right rotation. The fixed plate 4 is positioned by the fit of the positioning ring 5 and the fixed plate 4. With the tightening operation of the adjustable handle screw 6, the installation position and angle of the fixed plate 4 can be precisely adjusted, providing a flexible and stable installation base for the wire guide wheel assembly 7. The wire guide wheel assembly 7 is fixed on the fixed plate 4 by threaded connection. The front and rear positions of the wire guide wheel 72 can be precisely adjusted by adjusting the thread insertion depth according to actual production needs. After adjustment, the nut is tightened for secondary tightening to prevent loosening during equipment operation.

[0027] The cable guide wheel assembly 7 mainly consists of a cable guide wheel fixing shaft 71, a cable guide wheel 72, a small shaft 73, a spacer 74, and a flange bearing 75. The outer circle of the small shaft 73 is machined with high precision, and the surface finish meets specific technical standards. It forms a precise sliding fit with the inner hole of the bearing, ensuring the smooth rotation of the cable guide wheel 72. The small shaft 73 is firmly fixed to the cable guide wheel fixing shaft 71 by two bolts arranged at a 90-degree angle. This unique bolt layout design effectively enhances the stability of the small shaft 73 installation and prevents it from shifting during equipment operation. A spacer 74 is set between the cable guide wheel 72 and the cable guide wheel fixing shaft 71. Its main function is to fix the inner ring of the flange bearing 75 and provide a stable rotation support structure for the cable guide wheel 72, thereby significantly reducing the sway amplitude when the cable guide wheel 72 rotates.

[0028] The crimping wheel assembly 8 consists of a crimping wheel 81, a one-way bearing 82, a crimping wheel fixing plate 83, a flange bearing 84, a support rod 85, an outer shaft clip 86, and a spacer 87. The surface of the crimping wheel 81 is made of a special soft material, and its shape and angle are specifically designed according to the contour of the crimping wheel 81. The two achieve a precise match, which ensures that the optical fiber in the cable tray is effectively pressed while minimizing damage to the surface of the optical fiber. The one-way bearing 82 is installed in the inner hole of the crimping wheel 81, giving the crimping wheel 81 a one-way rotation characteristic, that is, only the crimping wheel 81 is allowed to drive the optical fiber outward, effectively preventing the optical fiber from retracting and ensuring the continuity and stability of the cable laying process.

[0029] The pressure roller 81 and the one-way bearing 82 are fixed on the pressure roller fixing plate 83. The pressure roller fixing plate 83 and the support rod 85 are connected by the flange bearing 84 and the spacer 87. The outer shaft clip 86 is used to fix the outside of the support rod 85. All components work together to build a stable and reliable pressure roller assembly 8 structure system, ensuring that the pressure roller 81 runs stably during operation.

[0030] The external thread cylinder 9 is mounted on the fixed plate 4 via the cylinder fixing bracket 10. Utilizing the external thread structure, the cylinder mounting position can be easily and precisely adjusted to adapt to the usage requirements under different production conditions. The external thread cylinder 9 is connected to the spherical bearing 11 by a self-aligning connector 12. This self-aligning connector 12 can achieve free rotation of the angle, effectively compensating for angular deviations caused by component installation errors or during operation, and ensuring accurate transmission of cylinder action. In addition, the cylinder is connected to the air pipe by a quick-connect fitting 13, which features quick connection and good sealing, facilitating daily equipment maintenance and pipeline replacement operations.

[0031] In summary, by optimizing the structural design, the following objectives are achieved: First, to improve the overall strength and rigidity of the cable tray support, effectively suppressing the vibration of the support during equipment operation; second, to improve the assembly method of the cable tray and the small shaft, reducing the left-right sway of the cable tray and improving the accuracy of cable routing; and third, to innovate the design of the pressure roller assembly and cable routing path, avoiding direct contact between the optical fiber and the device components, eliminating the problem of scratches on the optical fiber surface, thereby comprehensively improving the quality of optical fiber take-up and production efficiency.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
