胶带纵向撕裂是胶带输送机最严重、经济损失最大的一种事故。国外从70年代初,开始研究胶带撕裂保护。采用的保护多数为机械式的。如西德采用横向机械振动的方法,苏联和波兰采用旋转滚轮组和空转弹簧辊子系统等。70年代末至80年代初,西德、日本、苏联、美国、英国等对胶带撕裂保护的研究,从机械式发展到电气保护。成功的有:嵌入法、光电传感技术和超声波扫描技术等。 Longitudinal tear tape is the most serious belt conveyor, the largest economic loss of an accident. Abroad from the early 70s, began to study tape tear protection. Most of the protection used is mechanical. For example, West Germany adopted the method of transverse mechanical vibration, and the Soviet Union and Poland adopted the rotating roller set and idler spring roller system. From the late 1970s to the early 1980s, West Germany, Japan, the Soviet Union, the United States, Britain and other research on tape tear protection, from mechanical development to electrical protection. Successful are: embedded method, photoelectric sensing technology and ultrasonic scanning technology.
