Background
The optical fiber coloring machine is widely applied to the first working procedure of optical cable manufacture: and (3) a coloring process. The curing oven of the coloring machine is a device for curing coloring ink on the optical fiber, and the design of the curing oven plays a vital role in the quality of coloring and curing the optical fiber. The coloring and curing process of the optical fiber coloring machine is shown in fig. 1, a coloring ink heating component is arranged above a curing oven 5, an inlet die seat 6 of the curing oven is fixedly connected to an inlet of the curing oven, an existing inlet die 7 of the curing oven is arranged on the inlet die seat 6 of the curing oven, and the existing inlet die 7 of the curing oven and the inlet die seat 6 of the curing oven are detachably connected. The optical fiber uncolored section 3 passes through a coloring ink heating component consisting of a coloring mold 1 and a coloring mold seat 2 from top to bottom, coloring ink is coated on the surface of the optical fiber to form an optical fiber colored section 4, the optical fiber colored section 4 enters a curing furnace 5 from top to bottom through an existing inlet mold 7 of the curing furnace, the optical fiber colored section 4 is irradiated by a UV lamp outside the quartz tube in the curing furnace 5 for carrying out ink catalytic curing treatment, and the quartz tube is a device for isolating the optical fiber colored section 4 from the air in the curing furnace and continuously fills nitrogen into the quartz tube to prevent the ink from oxidizing.

Disclosure of Invention
Disclosure of Invention
In order to solve the problem that the optical fiber curing is affected by the fact that coloring ink of an optical fiber coloring machine enters a curing oven in the background art, the invention provides an inlet die of the curing oven for the optical fiber coloring machine.
The technical scheme of the curing oven inlet die is as follows: the shape of the curing oven inlet die 8 is a cylinder, a circular groove 801 coaxial with the cylinder is arranged on the upper plane of the cylinder, a conical boss 802 protruding vertically upwards is arranged at the center of the bottom surface of the circular groove 801, the generatrix of the conical boss 802 is an inward bending arc or straight line, the height of the conical boss 802 is the same as the depth of the circular groove 801, a vertical downward optical fiber through hole II 803 is arranged at the center of the upper end surface of the conical boss 802, and the optical fiber through hole II 803, the conical boss 802 and the circular groove 801 are coaxial with the cylinder of the curing oven inlet die 8;
the outer diameter of the cylinder of the curing furnace inlet die 8 is 32-45 mm, and the height is 15-20 mm; the caliber of the circular groove 801 is 70% -90% of the outer diameter of the cylinder, and the depth is 60% -70% of the height of the cylinder; the outer diameter of the bottom surface of the conical boss 802 is 75% -80% of the caliber of the circular groove 801, the outer diameter of the upper end surface of the conical boss 802 is 13-15 mm, and the height of the conical boss 802 is the same as the depth of the circular groove 801; the aperture of the optical fiber through hole II 803 is 4-5 mm;
the present invention will be further described below, and the curing oven inlet die 8 of the present invention is a die for a curing oven inlet of an optical fiber pigmenting machine.
The center of the inlet die 8 of the curing oven is an optical fiber through hole II 803, the optical fiber through hole II 803 is used for allowing the optical fiber coloring section 4 to pass through the curing oven, and the optical fiber through hole II 803 is sized so as to allow the optical fiber coloring section 4 to pass through without shaking the optical fiber coloring section 4. Because the size of the fiber through hole II 803 is too small, the fiber penetration is difficult; the size of the optical fiber through hole II 803 is too large, and the air flow passing through the inlet die 8 of the curing oven is too large, so that the coloring section 4 of the optical fiber shakes, and the aperture of the optical fiber through hole II 803 is 4-5 mm.
The outer circle size of the curing oven inlet die 8 is matched with the curing oven inlet die seat 6, and is the same as that of the existing curing oven inlet die, and in order to adapt to curing ovens of different types, the outer diameter range of the cylinder of the curing oven inlet die 8 is 32-45 mm. The curing oven inlet die 8 is arranged on the curing oven inlet die seat 6, because the curing oven inlet die 8 needs to be cleaned periodically, the curing oven inlet die 8 is convenient to clean after being disassembled, and the curing oven inlet die 8 is arranged on the curing oven inlet die seat 6 and is designed to be disassembled.
The caliber and depth of the circular grooves 801 are factors that determine the ink capacity of the grooves. The depth of the groove is not too shallow, the capacity is small due to too shallow depth, frequent cleaning is needed, the depth of the groove is not too deep, the ink is not easy to clean due to too deep depth of the groove, the difficulty of cleaning the ink is increased, the caliber range of the circular groove 801 is 70% -90% of the outer diameter of the cylinder, and the depth range of the groove is 60% -70% of the height of the cylinder.
The conical boss 802 protruding vertically upward on the bottom surface of the circular recess 801 in the curing oven inlet die 8 is to prevent the colored ink dropped from the ink heating seat in the above colored ink heating part from entering the inside of the curing oven, and to introduce the colored ink drop into the circular recess 801 around the conical boss 802 of the curing oven inlet die 8. The existing inlet die 7 of the curing oven used originally is designed for a conical groove 701, and when the colored ink drops, it will flow into the curing oven along the conical groove 701 and thus into the quartz tube.
The conical boss 802 in the curing oven inlet die 8 is surrounded by a circular groove 801, the circular groove 801 being capable of containing pigmented ink flowing down the protruding conical boss 802. When the colored ink is accumulated to be close to two thirds of the round grooves, the colored ink is cleaned in time, and overflow is prevented.
The upper end face of the conical boss 802 is flush with the upper end face of the curing oven inlet die 8, the outer diameter of the upper end face of the conical boss 802 is related to the aperture of the optical fiber through hole II 803, and the outer diameter of the upper end face of the conical boss 802 is 3-4 times as large as the aperture of the optical fiber through hole II 803 to be the best choice.
The boss is a conical side surface with respect to the bottom surface of the circular groove 801 such that a buffer transition is formed from the upper end surface of the conical boss 802 to the bottom surface of the circular groove 801, and the coloring ink droplets that have landed on the conical side surface do not splash. If the vertical cylindrical boss is provided, the colored ink can be prevented from entering the curing oven partially, but the colored ink which is dropped on the bottom surface of the groove is easy to splash to cause secondary pollution. According to the invention, the gradient of the conical surface is integrated, the capacity factor of the circular groove for containing ink is integrated, the outer diameter of the bottom surface of the conical boss 802 is 75% -80% of the caliber of the circular groove 801, the outer diameter of the upper end surface of the conical boss 802 is 13-15 mm, and the height of the conical boss 802 is the same as the depth of the circular groove 801;
when the curing oven inlet die 8 is used, the existing curing oven inlet die 7 is detached from the curing oven, the curing oven inlet die 8 is replaced, and other equipment and working procedures are not changed, so that the optical fiber coloring quality can be improved, and the labor intensity of workers can be reduced.
The beneficial effects of the invention are as follows: the invention changes the conical groove structure of the existing inlet die of the curing oven, adopts the structure that the conical boss is arranged in the circular groove, so that the coloring ink dripped from the coloring ink heating component of the optical fiber coloring machine can not enter the quartz tube in the curing oven, the coloring curing quality of the optical fiber is ensured, the labor intensity of workers is lightened, and the production capacity is improved.
