Abstract

The invention provides a preheating device for optical fiber with coating resin, the inlet end extends into the resin bucket through the input pipeline, and the outlet end is connected with the coating Hafur mold through the output pipeline. The preheating device includes: a A hollow cylindrical outer tube for conveying resin; an annular outer layer electric heater, which is close to the outside of the hollow cylindrical outer tube; several outer layer temperature sensors connected with the outer tube; an annular guide installed in the center of the outer tube Flow sleeve; an internal heating electric heater, set in the annular flow guide sleeve; a built-in temperature sensor, close to the internal heating electric heater; a heating power supply, providing electric energy for the outer layer electric heater and the internal heating electric heater; several A digital temperature controller whose interface is connected with the outer layer temperature sensor and the built-in temperature sensor. The invention has simple and compact structure, convenient operation and maintenance; effectively solves the problem of rapid dynamic and uniform heating of resin materials, precise temperature measurement and temperature control, improves the quality of production technology, and reduces the material cost of resin delivery system components in equipment manufacturing.

Description

technical field [0001] The invention relates to a resin preheating device, in particular to an optical fiber with coating resin preheating device whose inner and outer layers of the conveying pipeline can be heated. Background technique [0002] In the manufacturing process of optical fiber ribbon cable, there is an optical fiber ribbon process, which involves primary and secondary ribbon forming technology. At present, the preheating device for optical fiber with coating resin in primary and secondary ribbon forming equipment at home and abroad can generally only be equipped with multi-section external electric heaters on the outside of the optical fiber with coating resin delivery pipe in the resin barrel. Measure and control the heating temperature. This method heats the coating resin by lengthening the preheating path, and the speed is slow and the uniformity is poor, so it cannot be applied to the high-speed optical fiber paralleling process.
