CCD测宽调速系统在轮胎挤出生产线中的应用

Application of CCD Width Measurement and Extrusion Speed Control System in Tire Extrusion Line

介绍电荷耦合器件(CCD)测宽调速系统在轮胎挤出生产线中的应用。在胎面挤出工艺中,合理调整CCD测宽调速系统的测量控制参数,可保证胎面宽度波动在规定范围内;与未采用CCD测宽调速系统相比,采用CCD测宽调速系统生产的胎面平均质量更接近规定质量,偏倚系数较小,过程能力指数较大,但变差略有增大。在挤出生产线上安装CCD测宽调速系统,可以减小半成品质量差异,提高挤出工艺的稳定性和加工能力,降低劳动强度。

In this paper, the application of charge-coupled device （CCD） width measurement and extrusion speed control system in tire extrusion line was presented. The width of extruded tread was well control with adjustment of control parameters. Compared with the system without CCD,the average quality of tire crown produced by the system with CCD was better with smaller bias coefficient and larger process capability index, while the variation increased slightly. With CCD system, the quality difference of semi- finished products was reduced, and the extrusion stability and processing capability were improved.
