AI Technical Summary
Existing fiber drawing equipment calibration technology relies heavily on manual intervention, is inefficient, costly, or has complex systems with poor dynamic adaptability, and cannot meet the demands of modern fiber production for high precision, high efficiency, and low cost.
An infrared transmitter and receiver are used to adjust the motor, enabling automatic or manual calibration. Combined with a controller, the device can detect component offsets in real time and adjust their positions, achieving fast and high-precision calibration through infrared interaction.
It enables automatic, rapid, and high-precision calibration of optical fiber drawing equipment, solving the problems of low efficiency and poor accuracy of traditional manual calibration, and ensuring the quality and stability of optical fiber production.

Abstract
Claims
1. A wire drawing apparatus which can be easily calibrated, characterized in that, The system includes a vertically arranged drawing tower. Inside the drawing tower, from top to bottom, are a rod feeding device, a drawing furnace, an annealing tube, a cooler, a coating device, a curing device, a twisting wheel, a traction wheel, and a take-up device. A preform is fed into the drawing furnace via the rod feeding device. The end of the preform is heated to form the initial shape of the optical fiber, i.e., the bare fiber. The bare fiber passes sequentially through the annealing tube, cooler, coating device, and curing device to form a finished optical fiber with a protective coating. The finished optical fiber is then wound onto the take-up device by the twisting wheel and traction wheel. It also includes an infrared emitter, multiple infrared receivers, and multiple regulating motors. The power shaft of each regulating motor is arranged radially along the drawing tower. The drawing furnace, annealing tube, cooler, coating device, and curing device are each connected to the power shaft of one of the regulating motors. The infrared emitter is fixed to the outside of the bar feeding device and the emission direction is downward along the axial direction of the drawing tower. An infrared receiver is respectively arranged on the outside of the drawing furnace, annealing tube, cooler, coating device, and curing device.
2. Drawing apparatus conveniently calibratable according to claim 1, characterized in that, When the laser emitted by the infrared emitter enters each of the infrared receivers, the wire drawing furnace, annealing tube, cooler, coating device or curing device that is fixed with the infrared receivers is in the initial position or the central collimation position.
3. A conveniently calibratable wire drawing apparatus as claimed in claim 1, wherein, It also includes a controller, the output terminal of each of the infrared receivers is connected to the controller, and the control terminal of the controller is connected to the drive control terminal of each of the regulating motors.
4. A calibratable wire drawing installation according to any one of claims 1 to 3, characterized in that A bare fiber diameter gauge is installed between the annealing tube and the cooler to measure the diameter of the bare fiber in real time. The bare fiber gauge is connected to the power shaft of an adjusting motor, and an infrared receiver is installed on the outside of the bare fiber gauge.
5. A calibratable wire drawing installation according to any one of claims 1 to 3, characterized in that A coating diameter gauge is installed at the rear end of the curing device to measure the diameter of the finished optical fiber in real time.
