In the chinese utility model with publication number CN211569607U, a film conveying device with correction function is disclosed, when the moving plate moves forward, the second conveying roller is instantaneously separated from the film, one side of the film with offset is recovered, then the moving plate moves backward, the first conveying roller is instantaneously separated from the film, and the other side of the film with offset is recovered, so as to complete the correction operation. Meanwhile, the correction of the film can be completed only by adjusting the second conveying roller: when the movable plate is relatively fixed and the sliding block moves, the rotating shaft of the second conveying roller rotates due to the cooperation of the gear and the rack, the roller body of the second conveying roller rotates under the action of film friction force, a differential speed is formed between the roller body and the rotating shaft, when the two rotating shafts rotate in the same direction, the rotating speed of the roller body is increased, and when the rotating shafts rotate in opposite directions, the rotating speed of the roller body is reduced, so that film deviation correction is completed. The whole device has flexible structure and good correction effect.

The device utilizes the differential formed between the roll body and the rotating shaft to rectify the film, but after the film deviates on the roll body, the phenomenon of over-loosening or over-tightening usually occurs on one side of the film, so that when the whole roll body and the rotating shaft form differential rectification, the rectification efficiency of the film is poor, and the film is difficult to quickly rectify, therefore, the film conveying device on the heat shrink film packaging machine is provided to solve the problems.
