Glass fiber sleeve coloring process and equipment

Abstract

The invention discloses a glass fiber sleeve coloring process which comprises the following steps: heating and shaping: a glass fiber sleeve is conveyed into a shaping device to be heated and shaped,and the heating and shaping parameters are as follows: the heating temperature range is set to be 265 to 275 DEG C, and the moving speed range of the glass fiber sleeve is set to be 2.5 to 3.5 m / min;and coloring: the glass fiber sleeve heated and shaped in the step S1 is transferred to a coloring device, the coloring device comprises a coloring pipe with a coloring head, color paste is containedin the coloring pipe, and the lower end of the coloring head abuts against the glass fiber sleeve transferred to the position below the coloring head all the time, so that the outer surface of the glass fiber sleeve is coated with the color paste through the coloring head, the color paste is red color paste, blue color paste or yellow color paste. According to the glass fiber sleeve coloring process provided by the invention, the glass fiber sleeve prepared by adopting the process of firstly heating, shaping and then coloring is more stable in coloring and does not fall off, the coloring is more uniform and stable, the shaping effect is good, and an edge line body can be prevented from scattering.

Description

technical field [0001] The invention relates to the field of casing coloring, in particular to a glass fiber casing coloring process and coloring equipment. Background technique [0002] At present, the surface of wear-resistant sleeves in the industry is colored to distinguish functions. When preparing colored glass fiber sleeves, the first solution is to weave colored yarns into a sheet structure and then shape it. The disadvantage is that the cost is high. The second option is to weave white yarn into a sheet structure and then paint it, and finally shape it. When setting it, it will be treated at high temperature, and the color will fall off. [0003] There are the following problems in the coloring of the existing coloring equipment. The color paste drops drop by drop to the surface of the wear-resistant casing, which cannot guarantee continuous coloring, resulting in discontinuous color on the surface of the wear-resistant casing after coloring; The equipment adopts a...

When preparing colored glass fiber sleeves, the first solution is to weave colored yarns into a sheet structure and then shape it. The disadvantage is that the cost is high. ;The second option is to weave white yarn into a sheet structure and then paint it, and finally shape it. When it is shaped, it will be treated with high temperature, and the color will fall off

[0003] There are the following problems in the coloring of the existing coloring equipment. The color paste drops drop by drop to the surface of the wear-resistant casing, which cannot guarantee continuous coloring, resulting in discontinuous color on the surface of the wear-resistant casing after coloring; The equipment adopts automatic equipment, and it is usually set how often to drip liquid, which cannot guarantee continuity, and there is a problem of uneven coloring of the painted sleeve; and the cost is extremely high, which is a heavy burden on the enterprise
