Description

Technical Field

[0001] The utility model relates to the technical field of speed detection of material conveying belts, in particular to a non-contact belt speed and material state detection device. Background Art

[0002] As a common material conveying equipment, conveyor belts are used in various material conveying occasions, especially in industrial production, such as processing plants, warehouses, ports, mines and other places. The most basic function of conveyor belts is to transport materials from one place to another. For example, ore can be transported from the excavation area to the processing area, and raw materials can be transported from one production line to the next. Conveyor belts can realize the automatic transportation of materials, thereby reducing labor intensity, improving production efficiency and reducing production costs. As the main component for carrying and conveying materials, in order to ensure that the materials can run effectively and smoothly, the conveyor belt speed needs to be detected in real time. By obtaining the belt running speed information, the running status of the conveyor belt and the status of the material above it can be judged. In the field of material sorting, the running speed of the conveyor belt and the running status of the material will have a great impact on the accuracy of material sorting. The instability of the conveyor belt speed will lead to the uncertainty of the material running status, which will cause the sorting equipment to be unable to accurately identify and effectively sort the materials. Therefore, the conveyor belt speed detection is very important in the material sorting industry, and even directly affects the stable and effective operation of the sorting equipment.

[0003] The existing method for detecting the speed of conveyor belts is mainly to install contact and non-contact speed measuring devices on the belts or rollers. Among them, the contact speed measuring device calculates the speed of the belt by detecting the rotational angular velocity of the roller in contact with the conveyor belt. Due to the speed loss of friction transmission between the belt and the roller, the sliding error of the belt on the roller, and the change of the roller diameter caused by the sticky material on the roller during the operation of the belt, the belt detection speed is inaccurate. In addition, the mutual friction between the belt and the roller causes the belt to wear quickly and the replacement frequency is high, which increases the cost of use. The ordinary non-contact speed measuring device is to weld a sensing surface on the side of the driven roller, detect the sensing area through the speed detector, and read the number of pulses to calculate the belt speed. This method reduces the degree of equipment wear, but when encountering bulk goods with a high metal content (such as ore, scrap metal, etc.), the speed measurement pulse will be disturbed during the belt transportation process, and there is a risk of inaccurate speed measurement. There may be a certain amount of slippage between the belt and the roller, and there will be a large error in measuring the rotation speed of the roller and converting it to the speed of the belt.
