A film conveying device that overcomes the bending of long cantilever

Abstract

The invention discloses a film conveying device that overcomes the bending of a long cantilever. The key points of the technical proposal are: a film conveying device that overcomes the bending of a long cantilever, including a conveying frame, which is horizontally slidably connected to a sliding platform, and the sliding platform is fixed There is a hollow conveying rod arranged horizontally. The end of the hollow conveying rod away from the sliding table is provided with a joint, and the joint is provided with two feeding heads that are up and down symmetrical. The film is placed on the upper surface of the feeding head located above. The hollow The conveying rod is provided with a drive mechanism that drives the two feeding heads to move away from each other to move the popsicles and stick to the inner wall of the pipe. The conveying frame is provided with a moving assembly that drives the hollow conveying rod to move axially along the hollow conveying rod. The conveying frame A supporting wheel is rotatably connected to one end close to the feeding head, and the hollow conveying rod abuts against the upper side wall of the supporting wheel. The present invention can conveniently expand the two film holders and make the film adhere to the inner wall device, while avoiding the bending of the hollow conveying rod.

Description

technical field [0001] The invention relates to the field of weld seam detection, in particular to a film conveying device that overcomes the bending of a long cantilever. Background technique [0002] X-rays are generally used to detect the welds of pipes, and the welds of pipes are imaged through film. The existing technology relies on manual use of adhesive tape to paste the film on wooden round rods, and then through manual positioning with the naked eye. The location of the transillumination needs to place pads to make the film close to the workpiece, and it is necessary to feed the film into the tubular workpiece during the weld flaw detection process. The length of the wooden rod ranges from 200mm to 2000mm. [0003] The film is bound to the wooden rod and then inserted into the inner cavity of the pipe to inspect the weld seam of the pipe, which is inefficient, wastes labor costs, and the positioning accuracy is low. It is completely positioned by the naked eye. Ina...
