The belt conveyor fixed winch Ratchet Buckle, on which an automatic control system can form an automatic tensioning device, is a widely used tensioning form in modern large belt conveyors. Because the automatic tensioning device needs to complete the automatic tensioning process, The structure and control of the tightening device are more complicated;
The biggest difference between automatic tensioning and fixed tensioning devices is that it has sensing elements and control systems. Due to the harsh use environment of the bulk material belt conveyor equipment, it has a great impact on the sensing elements and control system. Practical automatic The design and use of the tensioning device must fully consider the impact on the environment. In order to solve the problem, various automatic tensioning devices have been proposed or used;
From the control method, the automatic tensioning device is divided into a stable type, a follow-up type, and a comprehensive type with both stability and follow-up characteristics. The stable type automatic tensioning device does not depend on the change of the conveyor load, the adhesion of the nylon conveyor belt and the drive roller Conditions and other parameters, it can set the Cargo Tie Down under different working conditions according to the starting, braking, normal operation, and other working conditions, and the tensioning device in one working condition is equivalent to the fixed tensioning device. Therefore, it only It can keep the tension at the rubber separation point constant within a certain error range;
