Description
Technical Field
The invention relates to the field of optical cable manufacturing equipment, in particular to a micro-tension yarn winding device for optical fiber bundling.
Background
At present, optical fiber cable products are divided into layer stranding type and central tube type according to structures, and in order to improve the optical fiber density of the optical cable, increasing the number of optical fiber cores in a single sleeve becomes a preferred scheme. According to the requirements of industry related standards, the color marks of the optical fibers are 12 colors, and once the number of the optical fiber cores in the sleeve exceeds 12 cores, the 12-color optical fibers are bundled and distinguished by the marks of one bundle of optical fibers, so that communication accidents caused by wrong connection during optical cable connection and maintenance are avoided. The main forms of the current optical fiber bundle are an optical fiber ribbon, a yarn winding optical fiber bundle, a micro-tube optical fiber bundle and the like. The optical fiber bundles in the form of optical fiber ribbons are formed by extruding thin-wall tubes on the outer sides of the optical fiber bundles by adding a resin bonding process, namely filling cured resin between the optical fibers, in the production process of the optical fiber cables, and the optical fiber bundles in the form of micro-tube optical fiber bundles are formed by extruding thin-wall tubes on the outer sides of the optical fiber bundles. The yarn-wound optical fiber bundle is formed by winding a colored yarn on the optical fiber bundle according to a certain pitch, the optical fibers are bundled under the yarn bundling, and the color of the wound yarn can be used as an optical fiber bundle mark, so that the yarn-wound optical fiber bundle becomes a preferred scheme for reducing the cost of an optical fiber bundle-shaped optical cable product.
Because the optical fiber is usually a crystallized silicide protected by the cladding resin, lateral pressure and bending are extremely easy to weaken light transmission capability and even break, the tension of the yarns is required to be very small and the tension fluctuation is small when the yarns are directly bound on the optical fiber bundle, and meanwhile, the yarns on the optical fiber bundle cannot be piled up during the follow-up plastic coating processing. The existing high-speed spiral stranding and bundling method for winding the yarn optical fiber bundle has the defect of unstable tension control, the tension change of the full yarn and the shallow yarn is larger by taking the self resistance of the yarn cylinder as the tension control, when the tension is overlarge, the product is easy to damage, the qualification rate of the finished product is not high, when the tension is too low, the optical fiber bundle is loose, the subsequent production process is influenced, and the product quality risk is high.

Detailed Description
The technical scheme of the present invention will be clearly and completely described in the following detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The existing yarn winding device often causes yarn breakage with small tension resistance under the common influence of mechanical inertia of a rotating part, bearing resistance of a rotating shaft, pagoda shape of yarn groups and resistance of yarn paths in actual use, and cannot guarantee the quality of a wound optical fiber bundle. In order to solve the yarn breakage problem, under the condition of ensuring the winding pitch to meet the design requirement, the tension of the yarn wound on the optical fiber bundle is required to be tiny, so that the optical fiber bundle is ensured not to be loose, and the optical fiber is ensured not to be affected by the lateral pressure of the yarn, so that the light transmission loss is increased. In view of the above, the present invention provides a micro-tension yarn winding device for optical fiber bundling.
Referring to fig. 1-2, a micro-tension yarn winding device for optical fiber bundling can be integrally installed on an optical fiber ribbon production line and an optical fiber secondary plastic sleeving production line as part of the production line, is used for winding and bundling polyester fiber yarns (such as yarns for sewing) meeting standard chromatographic requirements on an optical fiber bundle, and comprises an assembly bracket 1, a yarn spool 2, a yarn spool driving part, a yarn pot 3 and a yarn pot driving part, wherein the assembly bracket 1 is designed into a waist-shaped pore plate, thereby meeting the requirement of the improvement and installation of the production line, and needing no additional floor-type bracket, thereby saving the installation space.
The yarn ball shaft 2 is provided with a yarn ball 10 on the shaft body inside the yarn pot 3, the shaft end is sleeved with a twisting mold 11, the yarn ball shaft 10 is a hollow shaft, a beam passing hole 13 for the optical fiber bundle 12 to pass through is formed in the yarn ball shaft along the axial direction of the yarn ball shaft, and meanwhile, the shaft body where the yarn ball 10 is installed is a conical body with the taper of 10-15 degrees and the angle of 10 degrees is optimal, so that the installation stability of the yarn ball 10 is ensured. The axis of the yarn cluster 10 is coaxial with the optical fiber bundle 12, and compared with the yarn winding mode in which the yarn cluster 10 rotates around the optical fiber bundle 12 in a planetary manner in the prior art, the device is more compact and easy to control.
The center position of the stranding die 11 is also coaxially provided with a wire passing hole 14 at a position corresponding to the hole of the wire passing hole 13, the aperture of the wire passing hole 14 is the sum of the enveloping circle diameter of the optical fiber bundle 12 and the diameter of the yarn 15 which is 1.5-3 times, and the diameter can be adjusted according to the actual optical fiber number in the optical fiber bundle 12, so that the optical fiber bundle 12 and the yarn 15 on the optical fiber bundle 12 penetrate through. In addition, a first yarn through hole 16 and a second yarn through hole 17 are respectively formed on the circumferential side wall of the yarn pot 3.
Example 1
Referring to fig. 3, the optical fiber bundle 12 is moved through the wire hole 14 and the beam passing hole 13 in a direction as shown. Yarn 15 is led out from yarn cluster 10, passes through first yarn through hole 16 to outside yarn pot 3, and then passes along the outer side wall of yarn pot 3 to second yarn through hole 17 and passes to inside yarn pot 3 to be bound to optical fiber bundle 12 at stranding die 11. In this embodiment, the yarn pot 3 rotates with the yarn 15, so the opening positions of the first yarn through hole 16 and the second yarn through hole 17 can be adjusted according to the actual situation, and the specific requirement is not required, and the line between the center of the two circles coincides with the axis of the yarn pot 3 better.
The yarn cluster 10 and the yarn pot 3 can coaxially rotate in the same direction or in the opposite direction according to practical conditions, and the yarn 15 is wound on the surface of the optical fiber bundle 12. In this embodiment, the yarn cluster 10 and the yarn pot 3 rotate in the same direction and in the same axis, the yarn cluster shaft servo motor 7 drives the yarn cluster shaft 2 through the second synchronous belt 8 to control the steering and the rotating speed of the yarn cluster 10 and the yarn 15, and the yarn pot servo motor 4 drives the yarn pot 3 to rotate through the first synchronous belt 5 and controls the steering of the yarn pot 3. The device controls the yarn pot servo motor 4 and the yarn ball shaft servo motor 7 by a programmable controller, and can control and regulate the rotating speeds of the yarn pot servo motor 4 and the yarn ball shaft servo motor 7 in real time according to the detected torque difference so as to achieve the purpose of controlling the tension of the yarn 15 and the winding pitch of the yarn 15 on the optical fiber bundle 12. Under the condition that the moving speed of the optical fiber bundle 12 is unchanged, the higher the speed of the same-direction rotation of the yarn group 10 and the yarn pot 3, the smaller the pitch of the yarn 15 wound on the optical fiber bundle 12, the closer the same-direction rotation speed of the yarn group 10 and the yarn pot 3, and the smaller the tension of the yarn 15 wound on the optical fiber bundle 12.
Example two
Referring to fig. 4-5, the fiber bundle 12 is moved through the line aperture 14 and the beam passing aperture 13 in a direction as shown. The yarn 15 is led out from the yarn cluster 10 and directly pulled to the surface of the stranding die 11, and is bound to the optical fiber bundle 12 after being attached to the surface of the enveloping stranding die 11. When the yarn 15 passes through the twisting mold 11, frictional force acts on the yarn 15, and a certain tension is applied to the corresponding yarn 15 when the yarn 15 is wound around the optical fiber bundle 12, so that the optical fiber bundle 12 can be restrained. Meanwhile, the circular arc surface 18 is formed by circular arc transition among the circumferential outer side surface and the end surface of the stranding die 11 and the inner side wall of the wire passing hole 14, so that the yarn 15 can be attached to the surface of the stranding die 11 for movement and continuously receives the action of friction force, and the roughness of the circular arc surface 18 is 0.8-1.6 mu m. The yarn cluster shaft servo motor 7 drives the yarn cluster shaft 2 through the second synchronous belt 8 to control the steering and rotating speed of the yarn cluster 10 and the yarn 15 so as to enable the yarn 15 to be wound on the optical fiber bundle 12. The yarn pot 3 can effectively prevent the yarn 15 from being disturbed by the outside, and the yarn pot 3 can select synchronous rotation or non-rotation and does not need to be required.
Example III
In this embodiment, a limiting die 19 is added on the basis of the second embodiment. Referring to fig. 6 to 7, a limiting die 19 is coaxially sleeved on the shaft body of the yarn ball shaft 2 between the yarn ball 10 and the stranding die 11, the limiting die 19 is in a ring shape, the inner diameter of the limiting die 19 is larger than the outer diameter of the stranding die 11, the inner side surface of the limiting die 19 is an arc surface 20, and the roughness of the arc surface 20 is 0.8-1.6 mu m. A connecting rod 21 is arranged on the circumferential outer side surface of the limit die 19 and is fixedly connected with the inner side wall of the yarn pot 3. Yarn 15 is led out from yarn cluster 10 and is bound to optical fiber bundle 12 after being attached to the inner side surface of limiting die 19 and circular arc surface 18 on stranding die 11. The limiting die 19 is provided to prevent the yarn 15 from being thrown under the action of the rotating centrifugal force and reduce friction between the yarn 15 and the twisting die 11.
In this embodiment, the inner diameter of the limiting die 19 is the sum of the outer diameter of the twisting die 11 and 2 to 10 times the diameter of the yarn 15, and the outer diameter and thickness are appropriate, so that the yarn cannot collide with the yarn package 10 after being mounted. The structure adopted in this embodiment significantly improves the friction and stability between the yarn 15 and the stranding die 11, thereby ensuring the yarn winding quality of the optical fiber bundle 12 and ensuring closer optical fibers.
Example IV
In this embodiment, a brush member is added on the basis of the second embodiment, as shown in fig. 8 to 9, the brush member is disposed inside the yarn pot 3, and the brush member acts at least on the portion of the yarn 15 between the yarn cluster 10 and the surface of the twisting mold 11 to force the yarn 15 to remain attached to the surface of the twisting mold 11.
