Abstract
The utility model relates to an optical fiber pre-drying device, and the optical fiber pre-drying device is heated by an electric heater which has an air duct. A running hollow cavity of the optical fiber is heated uniformly, and the temperature is measured by a platinum thermo-resistance and controlled by an electric control board component. The control temperature can be regulated in a range of 60 to 160 DEG according to need, and the temperature reaches to a constant temperature through an automatic control. Then a plastic molding of the optical fiber meets a cladding requirement of the process. The top surface of a drying assembly is provided with an asbestos plate, the side is provided with an insulating plate, and screws are assembled tightly. The utility model has simple and safe operation and maintenance.
Description
Technical field
The utility model belongs to the fiber optic cable manufacturing equipment technical field, is specifically related to the predispersed fiber drying device.
