Description
Technical Field
[0001] The utility model relates to the technical field of resin preheating, in particular to a device for preheating optical fiber ribbon coating resin. Background Art
[0002] Fiber ribboning is the process of bonding multiple optical fibers together in a specific chromatographic arrangement. The primary purpose of fiber ribboning is to increase fiber packing density, facilitate collective splicing, and reduce splicing time and costs. It also makes the fibers easier to identify and maintain, reducing unit costs. Currently, the fiber ribboning process requires coating the optical fibers with a layer of resin to enhance their mechanical strength.
[0003] In existing processes, the resin needs to be preheated during optical fiber ribbon coating before being fed into a Harv-type mold. Existing preheating devices use a conical flow equalizer and a guide sleeve to transform the resin into a hollow tube for transport. This is then heated by inner and outer electric heaters, which provide good heating results. However, this heating method has a drawback: if the inner heater is damaged, replacement is difficult, requiring numerous parts to be removed and resulting in prolonged equipment downtime. Therefore, a preheating device for optical fiber ribbon coating resin is proposed. Utility Model Content
