Description
Technical Field
The invention relates to an optical fiber winding technology, in particular to a godet wheel set, a godet mechanism, an optical fiber winding device and a novel optical fiber winding process.
Background
In the new process of winding optical fiber, the optical fiber needs to be wound on a winding disc alternately clockwise and anticlockwise, and the optical fiber also needs to be arranged back and forth on the winding disc along the axial direction, and a yarn guide hook with an optical fiber jumper wire prevention function is used at the moment to be used as an actuating element for pulling the optical fiber to do the above actions. The currently commonly used actuating element is a yarn guiding hook (commonly called as a pig tail) on a textile machine, and has the advantages of simplicity and feasibility: the optical fiber can not run out from the yarn guide hook in the running process of the optical fiber, and the requirement of the optical fiber winding process is basically met.
However, because the sliding friction is adopted between the optical fiber and the yarn guide hook, when the optical fiber meets various arrangement requirements, the wrap angle of the optical fiber and the yarn guide hook can be changed, and the friction force can be changed. When the winding disc rotates anticlockwise, the friction force is about 50g; when the winding disc rotates clockwise, the friction force is about 25g, and the friction force is larger than the allowable stretching force range of the optical fiber by 20g, so that the phenomenon of breakage of the optical fiber is easy to occur in the winding process, and the requirements of a new optical fiber winding process cannot be met.
Disclosure of Invention
The invention aims to solve the technical problems that: when the existing yarn guide hook is used as an executing element to carry out a new process of winding the optical fiber, the friction force generated between the optical fiber and the yarn guide hook is larger than the allowable stretching force of the optical fiber, so that the optical fiber is easily broken.
The invention aims to provide a yarn guide wheel set, a yarn guide mechanism, an optical fiber winding device and a novel optical fiber winding process, wherein the yarn guide wheel set is used for replacing the existing yarn guide hook, so that the friction force between the yarn guide hook and the optical fiber can be reduced to be within the allowable stretching force range of the optical fiber in the optical fiber winding process, the breakage of the optical fiber is prevented, and the requirements of the novel optical fiber winding process are met.
In order to achieve the above object, a first aspect of the present invention provides a godet wheel set, including a fixed plate, a first pulley, a second pulley, and a third pulley; the fixed plate is horizontally arranged, the first pulley and the second pulley are vertically arranged on the front side of the fixed plate in a staggered mode through pulley brackets, the centers of the two pulley grooves are the same in height, and the first pulley is positioned in front of the second pulley; the third pulley is horizontally arranged at the rear side of the fixed plate through a pulley bracket, and the groove bottom elevation of the top pulley groove is the same as the center heights of the first pulley groove and the second pulley groove.
The first pulley and the second pulley are vertically arranged, so that the optical fiber is always positioned in 2 vertical pulley grooves at the same time, and the optical fiber is ensured not to fall off when being switched from one pulley to the other pulley. The first and second pulleys are staggered in the front-back direction, because if two pulleys are arranged side by side, when the optical fiber is moved out of one pulley groove and does not enter the other pulley groove, the pulleys just move upwards or downwards, and the optical fiber can fall out of a gap between the two pulleys. The third pulley mounted horizontally is designed because: the optical fiber is wound on the winding disc through the wire unwinding disc and the wire guiding mechanism, the wire guiding mechanism can drive the optical fiber to move up and down, and the positions of the wire unwinding disc and the winding disc are fixed, so that when the wire guiding mechanism moves up or down, the height of the optical fiber is always higher than that of the wire unwinding disc, the optical fiber has a downward pulling force, and the horizontally installed pulley ensures that the optical fiber cannot fall off from the first and second pulley grooves which are vertically installed in the front 2.
Further, the first pulley, the second pulley and the third pulley are all arranged on the pulley bracket through bearings. The pulley can rotate more flexibly due to the arrangement of the bearing, and the friction force between the guide wire hook and the optical fiber wire is further reduced.
Further, the pulley grooves of the first pulley, the second pulley and the third pulley may be V-grooves or rectangular grooves, and the surface roughness Ra of the inner wall of the pulley groove is 6.4 or more.
Further, the distance between the outer edges of the first pulley and the second pulley is 0.5 mm-2 mm, and the distance between the bottom of the pulley groove at the front side of the third pulley and the outer edge of the second pulley is 8 mm-20 mm when the pulley groove is observed from top to bottom along the vertical direction.
The relative position relation of the pulleys is limited, so that on one hand, the structure of the godet wheel set is compact, and the working efficiency is improved; on the other hand, if the edges of the pulleys are close together, no gap or too small gap is formed, the installation is inconvenient, the resistance to the rotation of the pulleys is increased, and the friction force between the optical fiber and the godet wheel set is increased.
Further, the first pulley and the second pulley have the same structure, the diameter of the outer circle of the pulley is 16 mm-20 mm, the depth of the pulley groove is 6 mm-8 mm, and the width of the pulley groove is 5 mm-8 mm; the diameter of the outer circle of the third pulley is 16 mm-20 mm, the depth of the pulley groove is 6 mm-8 mm, the groove width of the third pulley groove is 5 mm-8 mm when the third pulley groove is a V-shaped groove, and the groove width of the third pulley groove is 8 mm-20 mm when the third pulley groove is a rectangular groove.
The larger the godet set volume, the heavier the weight, the greater the friction of the pulley and the greater the likelihood of the fiber falling off of too small a chute size, so it is necessary to limit the godet set size to a reasonable range, which also facilitates processing and installation.
Further, the distance between the outer edges of the first pulley and the second pulley is 0.5 mm-2 mm when viewed from top to bottom along the vertical direction, and the first pulley is 8 mm-13 mm deviated to the right compared with the second pulley; the pulley groove of the third pulley is a rectangular groove, and the distance between the groove bottom of the pulley groove at the front side of the third pulley and the outer edge of the second pulley is 8-20 mm.
Ensuring that the optical fiber wires can be simultaneously positioned in respective pulley grooves when passing through the pulleys. The purpose is that the optical fiber wire will not fall off from between the two pulleys when switching from one pulley to the other.
In order to achieve the above object, a second aspect of the present invention provides a yarn guiding mechanism, which includes a traversing mechanism, wherein any one of the yarn guiding wheel sets is provided on the traversing mechanism, the yarn guiding wheel set is provided on the traversing mechanism through a fixing plate thereof, and the traversing mechanism drives the yarn guiding wheel set to reciprocate up and down.
In order to achieve the above object, a third aspect of the present invention provides an optical fiber winding device, which includes a winding disc, a wire unwinding disc, and the wire guiding mechanism, wherein the optical fiber on the winding disc is wound in the winding disc under the driving of the wire guiding mechanism.
In order to achieve the above object, a fourth aspect of the present invention provides a new optical fiber winding process, for the winding device, comprising the following steps:
step one, optical fiber wires are sent out from a wire releasing disc, pass through the upper surface of a third pulley groove, and sequentially bypass a second pulley groove and a first pulley groove to reach a winding disc;
step two, the winding disc starts to rotate clockwise, the fiber guiding mechanism drives the fiber to be arranged from bottom to top along the axial direction of the winding disc, and when the fiber is arranged at the uppermost end of the winding disc, the winding disc stops rotating and rotates reversely;
when the rotation direction of the winding disc is changed from clockwise to anticlockwise, the pulley mainly used for bearing the movement of the optical fiber wire is changed from the second pulley to the first pulley, at the moment, the optical fiber wire is driven by the wire guide mechanism to be arranged from top to bottom along the axial direction of the winding disc, and when the optical fiber wire is arranged at the bottommost end of the winding disc, the first circulation of the optical fiber wire arranged on the winding disc is ended;
step four, stopping and rotating the winding disc clockwise again, and starting the arrangement of the optical fiber wires of the next round; and (3) repeating the steps circularly until the arrangement quantity of the optical fiber wires on the winding disc reaches the requirement, and stopping winding.
The invention has the beneficial effects that:
the yarn guiding hook adopts the yarn guiding wheel set in a rolling friction mode to replace the yarn guiding hook in the original sliding friction mode, so that the friction force between the optical fiber and the yarn guiding hook is greatly reduced. When the godet wheel set is used in a new optical fiber winding process, when the winding disc rotates anticlockwise, the friction force is not more than 13g; when the winding disc rotates clockwise, the friction force is not more than 8g, and the friction force is within the allowable stretching force range of the optical fiber.
