玻璃管生产过程中外径检测与控制

Outside Diameter Measurement and Control on Glass Tubing Drawing Line

玻璃管作为玻璃生产中的中间产品,主要用来生产安瓿、荧光灯管等产品。由于这些最终产品对玻管外径都有一定的要求,因而应把外径作为质量检验的一项主要指标。 玻璃管的生产方式有水平拉管(Danner法)、垂直引下,垂直引上以及垂直转水平拉管(Vello法)等,其生产过程都是连续的。为了获得合格的产品。

This paper describes two on-line methods to measure outside diameter of glass tubes--contact method and noncontact method (including rotating mirror method and tuning-fork method) and the comparison of their principles and apparatus. This paper also describes the mechanism and working principles of pulse generation, counting and pulse distribution, shift register, output and setting in automatic glass tube O. D sortion and control system.
