Abstract

The invention provides a sleeve tube roundness control method and device that are used for injecting compressed gas into a sleeve tube from a machine head of an extruder via a pressure stabilizing and air charging device, an inner part of the sleeve tube can be supported via the compressed gas, diameter uniformity and roundness of the sleeve tube can be ensured. The roundness control method disclosed in the invention comprises the extruder and the pressure stabilizing and air charging device, the pressure stabilizing and air charging device is mounted on the machine head of the extruder, and the compressed gas can be guided into the sleeve tube from the machine head of the extruder via the pressure stabilizing and air charging device.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a roundness control method and a roundness control device for a sleeve. Background technique [0002] At present, with the advent of the 4G era, as an effective means of large-capacity, long-distance transmission, fiber optic cables have been more widely used. Traditional ointment-filled optical cables have problems of environmental protection and cleanliness during production and construction. In addition, the country now attaches great importance to environmental protection and low-carbon, and dry-type optical cables have emerged as the times require. They are used in the construction of urban area networks and the transformation of triple play networks Among them, the fully dry optical cable has outstanding advantages such as environmental protection, low cost, light weight and easy laying, which will gradually replace conventional grease-filled optical cables, and its ...
