Background technique

Rubber is the basic raw material for tire production. Before tire production, it needs to be pre-processed by mixing, production line extrusion, calendering, and molding. In the mixing and preparatory processes, rubber is usually processed in the form of a film. During the transfer between processes, if there are sundries in the film, especially metal sundries, it will easily cause damage to the production and processing equipment, and it will also have a serious impact on the quality of tire production, so it needs to be detected and removed in time. The existing metal debris detection and removal method is: use the metal detector installed on the transfer conveyor belt between the preparatory processes to perform qualitative detection on the conveying film, once the metal detector detects that there is metal debris in the film, the conveyor belt must be stopped immediately Afterwards, the operator will search for the metal debris mixed in the film in the prompt area, and manually remove them, and then start the conveyor belt to run again, and continue the film transmission and detection. Obviously, this method of detection and elimination needs to frequently interrupt the film transmission process, which cannot guarantee the continuity and smoothness of the production connection between processes, which seriously affects the production and processing efficiency of the film, especially many metal debris are buried inside the film and It is very small, not only difficult to distinguish with the naked eye, but also cumbersome to remove by hand, which also significantly increases the labor intensity of the staff.
