激光在线测量连续挤出胎面断面尺寸

Continuous measurement for cross-sectional dimensions of extruded tread on line by laser system

介绍激光测量技术的原理及其在胎面挤出生产线上的应用。实际测量了 11 0 0 -2 0 ,12 0 0 -2 0等多种规格胎面断面面积和断面尺寸在正常生产条件下的波动情况。测量数据表明 ,生产线上连续挤出的轮胎胎面断面面积及冠宽、冠厚、肩宽和肩厚等断面尺寸的波动范围均较大。通过对测量数据的分析可查找干扰因素 ,调整挤出工艺 ,提高挤出胎面尺寸稳定性。

The principle of the laser measuring technology and its application to the extruding line of tread were introduced.The cross-sectional areas and dimensions of treads in various sizes of tire,such as 11.00-20,12.00-20 and so on,were measured under the normal production conditions.The results showed that the cross-sectional areas and dimensions,such as crown width and thickness,shoulder width and thickness,fluctuated in a larger range.The interference factors could be found by analyzing the measured data,and thus the dimensional consistancy of extruded tread improved by modifying the extruding process.
