Optical fiber coating even shaking device and method

Abstract

The invention discloses an optical fiber coating even shaking method. The optical fiber coating even shaking method includes the following steps that under the condition of heat preservation, a container containing an optical fiber coating is fixed to an even shaking table to control the even shaking table to move, so that an axis of the even shaking table moves in an inverted conical pendulum mode, and thus the optical fiber coating in the container is shaken evenly; and the axis is a straight line vertically penetrating through the geometric center of the even shaking table, the angle between the axis and the vertical direction is 10-20 degrees, and a conical pendulum moves at the speed of 10-30 rpm. The invention further discloses an optical fiber coating even shaking device. Accordingto the optical fiber coating even shaking method, the optical fiber coating can be shaken evenly and quickly, the pre-treatment time of the optical fiber coating is decreased, production energy consumption is reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of quartz optical fiber manufacturing, in particular to an optical fiber coating shaking device and a shaking method. Background technique [0002] With the commercialization of the fifth generation mobile communication technology (5G), the market for quartz optical fiber will further expand. In order to further expand optical fiber production capacity and reduce production costs, increasing the drawing speed has become one of the inevitable options for optical fiber manufacturers. With the continuous improvement of wire drawing speed and the continuous acceleration of production cycle, the probability and length of coating defects caused by uneven coating will increase accordingly, which will cause the loss of optical fiber and is not conducive to the reduction of cost. [0003] Coating defects are mainly caused by uneven coating, dirty molds and poor curing. Uneven coating is caused by incomplete dispersi...

AI Technical Summary

Problems solved by technology

With the continuous improvement of wire drawing speed and the continuous acceleration of production cycle, the probability and length of coating defects caused by uneven coating will increase accordingly, which will cause the loss of optical fiber and is not conducive to the reduction of cost

[0003] Coating defects are mainly caused by uneven coating, unclean mold and poor curing. Uneven coating is caused by incomplete dispersion of additives and high air bubble density in the coating before wire drawing

At present, the pretreatment of paint needs to be placed in an oven at 40-80°C for 6-8 hours, and the recovered paint is left to stand for more than 12 hours. The processing time is long and the heat preservation energy consumption is high, which is not conducive to rapid production and energy consumption reduction.
