A device for improving the production stability of the belt

Abstract

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. It is composed of compressed air precision pressure regulating valve, air pipe, double-set air tank large tank, double-set air tank inner tank, resin tank, etc. The air inlet of the compressed air precision pressure regulating valve is connected to the air source, and the air outlet is connected to the Double-set air tank large tank, double-set air tank inner tank is installed in the double-set air tank large tank, the double-set air tank inner tank is connected to the resin tank through the air pipe, and the resin tank is connected by the resin delivery pipe and has a mold. In the production process of the present invention, when the production of a reel and ribbon optical fiber is stopped, the residual air pressure in the resin tank is counter-pressured and the resin in the air pipe is not in contact with the air pipe connected to the compressed air precision pressure regulating valve, which ensures the precision pressure regulating valve Safe and stable production status. It solves the problem that the remaining air pressure in the resin tank will send the resin back to the compressed air pipe when the disc is changed every time when the machine is parked, causing the optical fiber to be scattered.

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 ...

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
