Problems solved by technology

This method has the following disadvantages: 1. The leaky plate works at high temperature, and the temperature sensor inside the leaky plate is always in contact with the high-temperature glass liquid, which makes the temperature sensor easy to age, thereby affecting the accuracy of the temperature sensor
2. Even if this method can control the temperature to stabilize at the ideal temperature, it cannot guarantee that the glass fiber linear density remains unchanged, because there are other factors that affect the glass fiber linear density

Abstract

The invention relates to a method and device for adjusting the linear density of glass fiber through correcting the bushing temperature in a real-time manner, which belongs to a glass fiber manufacturing industry. The method comprises the steps that: a signal representing the weight of a yarn group is produced; the yarn group weight signal is responded, and a weight difference value signal indicating the difference level between the weight of the yarn group and set weight is produced in light of a set weight value; the weight difference value signal is responded, and a bushing temperature correcting signal is produced in light of a characteristic curve or a characteristic database; a signal indicating the practical temperature of a bushing is produced; and the bushing temperature correcting signal and the bushing practical temperature signal are responded, a combinational feedback signal indicating the adjustment of the bushing temperature is produced and is responded, and the bushing temperature is corrected, so as to adjust the linear density of the glass fiber. Not only can linear density fluctuation of the glass fiber, which is resulted from the fluctuation of the bushing temperature, be adjusted, but also linear density fluctuation of the glass fiber, which is caused by the variation of wiredrawing flow, can be adjusted.

Description

technical field [0001] The invention relates to a method and a device for adjusting the linear density of glass fibers by correcting the temperature of a plug plate in real time, belonging to the glass fiber manufacturing industry. Background technique [0002] Glass fiber is widely used in all walks of life. In order to ensure the weight of glass fiber produced, the linear density of glass fiber must be controlled. The main factors affecting the linear density of glass fiber are: first, the temperature of the bushing, which affects the temperature of the bushing. The temperature of the molten glass affects the viscosity of the molten glass, which in turn affects the linear density of the glass fiber; the second is the winding speed of the wire drawing machine. The product will increase the outer diameter of the bobbin, so the winding speed of the bobbin must be adjusted to adjust the drawing speed of the wire drawing machine to ensure the drawing speed, and the drawing spee...
