1.张力控制系统在加工处理布、纸、胶卷等诸如此类成卷的材料,以及制造或加上电线和绳索等的过程中,为了保证和提高质量,准确控制张力是很重要的,使张力控制自动化、省力,就成了一项重要的任务。如卷筒纸这一类纸张,在加工过程中要卷进卷出,如果张力过大,则产生纵向绉纹,如果张力过小,则产生横向绉纹,因此在印刷机上一见这种情况,就用切纸机把纸张切断。为了防止这种情况,在卷进轴和卷出轴上各安装磁粉离合器、制动器,用来控制力矩,控制张
1. Tension Control System It is important to accurately control the tension during the processing of materials such as rolls, paper, film and the like, as well as the manufacture or incorporation of electric wires and ropes, etc. to ensure and improve the quality of the tension control Automation, effort, has become an important task. Such as paper webs of this type, in the process of rolling into the roll out, if the tension is too large, the resulting longitudinal crepe, if the tension is too small, the resulting lateral crepe, so saw this on the press , Cut the paper with the cutter. In order to prevent this situation, in the roll into the shaft and roll out the shaft on each installation of magnetic clutch, brake, used to control the torque, control sheet
