The anti-skid switch of the chain scraper conveyor is a protection device used to detect the slip between the conveyor belt and the driving roller and give an alarm. When the conveyor belt slides, it can be used to automatically trigger an emergency stop. Slippage is a serious failure phenomenon.The cause may be overload, belt jam, belt break, roller jam, abnormal motor speed, etc. If it is not stopped in time, it may cause serious damage to the equipment, fire and serious injury.
At present, the problems often encountered in the installation and use of slide switches widely used in chain scraper conveyors are as follows: there are many types of slide switches in chain scraper conveyors, and the applications are often not properly selected. Some products are difficult to adapt to the harsh environmental conditions on site, such as dust, moisture, and vibration. Some products are difficult to install on site, such as split products with speed probes and control boxes. On-site installation and wiring are troublesome.
Many products of the scraper chain conveyor judge slippage by comparing the difference between the actual speed of the conveyor belt and the rated standard speed. Therefore, it is necessary to have the function of avoiding the start and stop process of the chain scraper conveyor, and it is impossible to judge the start and stop of the chain scraper conveyor. The slippage that occurred during this process. However, during the startup of the chain scraper conveyor, due to the presence of acceleration, it is necessary to overcome the large static friction and the possibility of clogging that may occur.
