Coloring and curing mechanism of optical fiber coloring machine

Abstract

The invention discloses a coloring and curing mechanism of an optical fiber coloring machine and belongs to the technical field of optical cable processing devices. The optical fiber coloring machine comprises a machine frame box body, and the coloring and curing mechanism comprises a nitrogen inlet pipe provided with a first pressure regulating valve, a printing ink tank, a curing oven and an optical fiber guide device, wherein the printing ink tank and the curing oven are arranged on the machine frame box body; the nitrogen inlet pipe is provided with a three-way connector which arranged in the nitrogen inlet pipe at a position on the air outlet side of the first pressure regulating valve and is connected with the pipes of the printing ink tank and the curing oven respectively; and a second pressure regulating valve is arranged on the pipe connecting the three-way connector and the curing oven. The coloring and curing mechanism of the optical fiber coloring machine has the advantages of increasing nitrogen volume acquired by the printing ink tank, preventing excess nitrogen flow in the curing oven, improving the coloring speed, guaranteeing processing efficiency, saving nitrogen and protecting environment.

Description

technical field [0001] The invention belongs to the technical field of optical cable processing devices, and in particular relates to a coloring and curing mechanism of an optical fiber coloring machine. Background technique [0002] As is well known in the industry, in order to facilitate the identification of optical fibers, it is necessary to smear ink on the outside of the optical fibers, that is, to color the optical fibers, so that each of the several optical fibers in the same optical cable has a corresponding color, which is conducive to improving the laying or maintenance. construction efficiency in the process. In view of this, optical fiber manufacturers including the applicant are almost without exception equipped with optical fiber coloring machines. Although there are imported and domestic optical fiber coloring machines, their structures are roughly the same. At present, the optical fiber coloring machine commonly used by my country's optical fiber production...

Problems solved by technology

However, this disposal method has an alternative problem of taking care of one thing and losing another. The so-called focus on this, that is, the processing efficiency can be improved, and the so-called loss of the other, that is, because the amount of nitrogen entering the curing furnace is also increased at the same time, it will cause serious problems. waste, which ultimately increases the cost of fiber processing

[0004] In view of the above, it is necessary to find a reasonable balance between not affecting the nitrogen supply required by the ink tank and not causing the waste of nitrogen in the curing furnace. For this reason, the applicant has carried out a large number of expert consultations and literature searches. Obtaining technical inspiration that can be used as a reference, the result is: technical information with no expert hands and uninspiring technical information in the literature
