# Conveyor belt manufacturer mechanical design latest scientific calculation requirements

During the design process, we can divide the conveyor line into three sections: the starting horizontal section, the inclined section, and the last horizontal section. If the starting stress of the conveyor belt is restricted, the rubber belt mechanical starting device is used. It is not safe to start the system. It is assumed that the quality between the loosening of the drive roller and the tensioning device is neglected. The tensioning device is far away from the driving device and should be considered in the calculation, but under the condition of slipping. The tension of the belt is mainly controlled by the tensioning device. If the tensioning device is installed near the head roller, it is obvious that an external force much smaller than this braking force will cause the rubber belt of the head roller to relax. The solution to this problem is to apply a braking force on the tail drum that will increase rather than reduce the contact pressure between the belt and the drum. However, further calibration of the tail drum indicates an ordinary smooth tail drum. Dynamic tension is unlikely to produce a sufficient ratio of tight-side tension to loose-side tension, so the following measures should be taken: increasing tension The tail roller plus the protective surface or the thickening roller to increase the wrap angle of the tail drum can realize the operation requirements. It should be noted that the above calculation is based on the maximum friction loss, thus obtaining the minimum sliding distance, due to the maximum Most equipment is operated under a variety of different conditions, so braking and sliding problems should be studied for each frictional resistance value. Lower frictional braking force indicates a larger sliding distance or larger braking.

Finally, it needs to be additionally stated that according to different models, the calculation of the running resistance of the belt conveyor often uses two calculation methods: the simple calculation method and the detailed calculation method. The simple calculation method uses the total running resistance coefficient of the conveyor. Calculating the running resistance, the obtained driving power, the tension and strength parameters of the circulating conveyor belt are all approximate. This method can meet the accuracy requirements for the belt conveyor with small bandwidth and short transportation distance, but due to the transportation distance. The structure of the conveyor is becoming more and more complicated, and the structure of the conveyor is more and more complicated. The error of the approximation algorithm is quite significant. Therefore, the detailed calculation method is proposed, that is, the piece-by-section calculation method is also called point-by-point calculation. The essence is that according to the geometric characteristics of the layout of the belt conveyor. The whole machine is divided into several sections, the running resistance is obtained step by step, and then the resistance of each section is integrated to find the total resistance. Although this method has a large calculation amount, the calculation result is more realistic, so for example, heat-resistant transportation The resistance to operation with equal mechanical transmission lines is mainly determined by the piece-by-stage calculation method.
