Description

Optical fiber disc locking device of ring winding machine

Technical Field

Background

The optical fiber disk is used for a carrier for long-distance optical fiber bearing and winding, is an indispensable bearing and winding disk for factory packaging of optical fiber products, and is generally standardized in the industry at present. However, according to different purposes and characteristics of various optical fibers, part of the optical fiber discs need to be customized, and the optical fibers are small in outer diameter and long in distance, and the lengths and the arrangement modes of the optical fibers are necessarily rewound by means of a ring winding device or a fiber dividing and rewinding device in the using process, so that the fixation of the optical fiber discs on a rotating disc or a shaft is very important.

As for the rotation form of the optical fiber tray, a rotation shaft type and a rotation tray type are common.

The rotation shaft type is a common rotation mode at present. At present, the shaft end is usually clamped by a fixing clamping block in a common shaft end fixing mode, so that the optical fiber disc is prevented from slipping, however, the fixing mode only can limit the axial movement of the optical fiber disc, but cannot play a good limiting role in circumferential rotation movement, the rotating shaft type is only suitable for the large-diameter large-aperture optical fiber disc, the rotation radial jumping amount is uncontrollable in small size and small aperture, and the thickness of the optical fiber disc is limited.

The rotary disk type is a rotation mode more suitable for a miniaturized customized optical fiber disk. Because of special occasions, the inner hole of part of the optical fiber disc is small, the external dimension is small, and the small shaft is not suitable to be designed into a rotating shaft form because the rotation radial jumping of the slender shaft is uncontrollable, a rotating disc is arranged on the fixed shaft, and the rotating disc drives the optical fiber disc to rotate. In this case, the locking of the optical fiber disc is achieved by the rotation of the optical fiber disc without the rotation of the elongated bearing shaft.
