Description

Technical Field

[0001] This utility model relates to the field of belt detection technology, and in particular to a belt tear detection device. Background Technology

[0002] Belt conveyors are important industrial continuous conveying equipment, widely used in the production of cement, metallurgy, chemical, steel, calcium carbide and other industries for material transfer. They are a crucial link in the entire production process. During the transportation of materials, belts are prone to longitudinal tearing due to long-handled sharp objects. Once a longitudinal tear accident occurs, it will affect normal production, leading to long-term shutdowns and significant economic losses. Therefore, it is necessary to conduct tear detection on belts during transportation.

[0003] Existing belt tear detection devices primarily employ non-contact methods, utilizing cameras and laser emitters. These are fixed to the belt conveyor frame via a support bracket. The laser emitter projects a laser beam onto the underside of the upper belt, while the camera captures an image of the area illuminated by the laser. This image is then processed, analyzed, and compared. If the image captured by the camera breaks, the detection device identifies a tear. This allows for timely detection of belt tears using a camera and laser emitter. However, this method of longitudinal belt tear detection can lead to false positives if the camera fails to detect the laser beam, potentially disrupting production. Utility Model Content

[0004] This invention provides a belt tear detection device to solve the technical problem that the above-mentioned belt longitudinal tear detection method may make a wrong judgment during the detection process because the camera does not detect the laser line, which may affect production.
