However, in actual applications, due to the influence of various factors such as material properties, conveying speed, equipment wear, etc., the conveyor belt often deviates, which not only affects the accuracy and stability of material conveying, but also may cause damage to the equipment and even threaten the safety of operators. Therefore, how to effectively correct the deviation of the guide chute has become an urgent problem to be solved in the field of material conveying. Most traditional guide chute deviation correction devices adopt a mechanical adjustment method, that is, the tension or position of the conveyor belt is adjusted manually or automatically. This method can solve the deviation problem to a certain extent, but it has the disadvantages of low adjustment accuracy, slow response speed, and low degree of automation. Utility Model Content

This shape is conducive to the stability of materials during the transmission process. Through the design of the lower tensioning component, dynamic tensioning is achieved by using springs and guide rods, which can quickly respond to changes in the tension of the transmission belt, maintain the tension of the transmission belt, reduce the probability of its deviation, and quickly adjust the belt position to improve the correction response speed. Each group of correction and warning components includes a correction part, a detection control part and an early warning part, which can realize real-time monitoring and automatic adjustment of the deviation of the transmission belt.
