The utility model discloses an industrial flaw detection X-
ray film developing
machine which comprises a film developing
machine body, a bottom plate is arranged below the film developing
machine body, universal
brake wheels are fixedly connected to the periphery of the bottom of the bottom plate, a plurality of stand columns are fixedly connected to the periphery of the top of the bottom plate, and the film developing machine body is installed outside the stand columns in a sleeving and sliding mode. A lifting
assembly is arranged between the film developing machine body and the bottom plate, and an X-
ray film inlet is formed in one side of the film developing machine body. By arranging the adjusting
assembly, the connecting frame, the second motor, the driving
assembly and other structures, after the second motor drives the main gear to rotate and is meshed with the driven gear to rotate, the conveying belt between the side plates can be conveniently adjusted to the proper position, and the first motor is used for driving the transmission roller to rotate to drive the conveying belt to rotate; and the released X-
ray film can be conveniently and automatically released, the problem that the X-ray film is manually held by hand to be released is solved, and the convenience in use is improved.
