Device for improving ribbon matrix production stability

Abstract

The invention relates to a device for improving ribbon matrix production stability, and belongs to the technical field of optical fiber ribbon cable processing. The device comprises a compressed air precision pressure regulating valve, an air pipe, a double-shell type large air tank, a double-shell type inner air tank, a resin tank and the like, wherein an air inlet of the compressed air precision pressure regulating valve is connected to an air source, and an air outlet of the compressed air precision pressure regulating valve is connected to the double-shell type large air tank; the double-shell type inner air tank is arranged in the double-shell type large air tank and is connected to the resin tank by the air pipe; and the resin tank is connected to a ribbon matrix mold by a resin conveying pipe. The device has the beneficial effects that when the production of a reel of ribbon matrix optical fibers is completed and the device stops operating in a production process, residual air pressure in the resin tank back presses resin sent to the air pipe, so that the resin is not in contact with the air pipe connected to the compressed air precision pressure regulating valve, thereby ensuring the safe and stable production state of the precision pressure regulating valve. The device solves the problem that when a conventional device stops operating and a reel is changed every time, residual air pressure in the resin tank can back press and send the resin to the compressed air pipe, which causes scattering of optical fiber ribbons.

Description

technical field [0001] The invention relates to a device for improving the stability of ribbon production, and belongs to the technical field of optical fiber ribbon and cable processing. Background technique [0002] Optical fiber ribbon cable is the core backbone optical cable in communication networks such as metropolitan area network and access network. It has the advantages of high density, compact structure, convenient fast connection and easy branching. The production of parallel optical fiber is the source production process of optical fiber ribbon cable, and it plays a vital role in the quality of parallel optical fiber in the entire optical fiber ribbon cable. At present, the production of tape optical fiber is to directly apply air pressure to the resin tank through a compressed air precision pressure regulating valve, and the tape resin in the resin tank is pressed into the tape mold through the resin delivery pipeline, and coated to the A bundled optical fiber ...

AI Technical Summary

Problems solved by technology

However, during the production process, when each group of optical fibers needs to be stopped for disk replacement, the compressed air precision pressure regulating valve stops working to supply air, and the residual air pressure in the resin tank sends the resin back to the compressed air pipe. After several After the first stop and repeated disk changes, the resin that is sent to the air pipe will flow into the precision pressure regulating valve and damage the pressure regulating valve, and the damaged pressure regulating valve cannot be normally delivered to the resin tank when the car is started again. Air pressure, resulting in quality accidents such as fiber optic strips, which cannot be produced normally
