Referring to fig. 7, on the basis of the first embodiment, the present embodiment arranges sliding joints 7 at two ends of the curing oven 4; the sliding joint 7 comprises a guide rail 71 arranged on the box body and a sliding seat 72 arranged on the guide rail 71, wherein a connecting plate 73 matched with the curing oven 4 is arranged on the sliding seat 72, and a second wire avoiding hole 74 matched with the first wire avoiding hole 22 is arranged on the connecting plate 73. The connecting plate can synchronously slide on the guide rail along with the sliding seat, and the purpose is to facilitate threading. When the equipment is used for the first time, the optical fibers need to penetrate through all the equipment one by one, if the sliding joints are not arranged, the optical fibers are difficult to penetrate through the curing oven, and through the arrangement of the sliding joints, the optical fibers are more convenient and faster to penetrate through the curing oven, and the improvement of the working efficiency is facilitated.
Referring to fig. 1, the sliding seat 72 of the embodiment is provided with a rubber pad (12) which is provided with a clamping groove. During initial threading, the optical fibers passing through the curing oven can be fixed in the clamping groove, so that messy or staggered optical fibers during threading are avoided.
The working principle is as follows: the first wire avoiding holes are preferably six, six optical fibers can be simultaneously colored and cured, and the corresponding second wire avoiding holes, second wire avoiding wheels, third wire avoiding wheels and coloring channels are all six. The optical fiber from the pay-off rack sequentially passes through a first wire avoiding rack, a third wire avoiding rack, a high-pressure coloring mold, a curing oven, a fourth wire avoiding rack and a second wire avoiding rack, and can be fixed through corresponding rubber pads on corresponding equipment while passing through the corresponding equipment. After threading is finished, the equipment can be started to continuously color and solidify the optical fiber. The production speed of the traditional single optical fiber coloring is 1500 m/min-3000 m/min, the production speed of the optical fiber coloring is 200 m/min-500 m/min, the corresponding function of the ultraviolet lamp tube is reduced, and the energy consumption is reduced; the invention simultaneously colors six optical fibers, improves the working efficiency, reduces the labor intensity and avoids the operations of midway transportation, storage and the like compared with the traditional single mode. The wavelength of the light emitted by the ultraviolet lamp tube is 365 nm-415 nm.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
