Description

Loop scanner with adjustable angle Technical Field The utility model relates to a loop scanner, in particular to an angle-adjustable loop scanner. Background The loop scanner is a key detection device for industrial production lines (such as steel rolling, continuous casting and the like) and is mainly used for monitoring and controlling the shape and position of loops formed by strips, plates or wires in the processing process in real time. The loop scanner comprises a base, an angle adjusting structure and a scanning probe, wherein the scanning probe is usually arranged on the base through the angle adjusting structure, the monitoring angle of the scanner can be changed through the angle adjusting structure, different process requirements are met, and the stability of the production process and the surface quality of materials are ensured. The common angle adjusting structure is divided into a manual adjusting structure and an automatic adjusting structure, wherein the manual adjusting structure is used for manually adjusting the inclination angle of a sensor through a mechanical structure (such as a rotating bracket and a bolt to be fixed), is suitable for a fixed process or a low-frequency adjusting scene, the automatic adjusting structure is suitable for high-frequency or dynamic process requirements, is usually adjusted by adopting a worm gear meshing effect, and can be accurately controlled through a remote control system.
