Abstract

The invention provides a glass tube diameter adjusting device applied in DANNER horizontal pulling tube production. The device comprises a filtering and pressure reducing device, an electric valve, a laser diameter measuring device and a controller; the filtering and pressure reducing device conducts filtering treatment and pressure reducing and stabilizing on high-pressure compressed air and outputs low-pressure gas to the electric valve; the electric valve adjusts the valve opening degree of the electric valve according to valve position and opening degree information carried in a control signal and outputs corresponding flow of low-pressure clean gas to a pulling tube driver blowing interface; the laser diameter measuring device measures the glass tube diameter, converts the glass tube diameter into a corresponding electric signal and transmits the electric signal to the controller; the controller converts the electric signal into the valve position and opening degree information of the electric valve in the PID control process and transmits the control signal carrying the valve position and opening degree information to the electric valve. According to the device, compressed air obtained after filtering and pressure reducing is used to provide the clean gas with the stable pressure, the flow of gas in a glass tube is automatically changed according to glass tube diameter changes, and therefore the glass tube diameter stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of DANNER (Danner) horizontal drawing tubes, in particular to a glass tube diameter adjusting device in the production of DANNER horizontal drawing tubes. Background technique [0002] In the production process of DANNER horizontally drawn tubes, the glass tubes must ensure the consistency of diameter. The consistency of the diameter is affected by the temperature of the glass liquid, the stability of the speed of the drawing machine and the stability of the blowing device inside the glass tube. The temperature of the molten glass is generally adjusted by PID control controlled by the proportion (P), integral (I) and differential (D) of the deviation, and the stability can be guaranteed. At present, more advanced equipment has adopted servo motor closed loop to control the speed of the pipe drawing machine, and the stability of the speed of the pipe drawing machine can also be guaranteed. [0003] In the a...
