Description

Technical Field

[0001] The present application relates to the technical field of flexible film production, and in particular to a deviation correction device for a flexible film rewinding machine. Background Art

[0002] Flexible film is a polymer sheet with a certain thickness and tough texture, and its water-impermeability is particularly remarkable. After the flexible film strip is rolled up on the winding core tube, a part of the flexible film strip will be partially offset along the axial direction of the winding core tube. At this time, the film rewinding machine must be used to rewind the roll of flexible film strip.

[0003] Existing film rewinding machines generally include a frame, a unwinding roller, a winding roller and a correcting roller. The unwinding roller is connected to a rotating motor for driving the unwinding roller to rotate, and the winding roller is connected to a rotating motor for driving the winding roller to rotate. The correcting roller is arranged on the frame between the unwinding roller and the winding roller and can move along the axial direction of the correcting roller itself. The correcting roller is also provided with two abutting sleeves for abutting the side edges of the flexible film strip. The two abutting sleeves are detachably connected to the correcting roller so that the distance between the two abutting sleeves can be adjusted according to the flexible film strips of different widths.

[0004] When rewinding a roll of flexible film strip, the worker can first fix the core tube sleeve of the roll of the strip on the unwinding roller, then wind one end of the strip around the correcting roller and pass it between the two abutment sleeves, then connect one end of the strip to the winding roller, and finally start the rotating motors on the winding roller and the unwinding roller to start rewinding; when the flexible film strip is wound to the offset part, the worker can correct the offset part by moving the correcting roller manually or with other equipment.

[0005] However, since the correction roller pushes the flexible film strip from one side of the flexible film strip with the help of the abutment sleeve to move the strip, it is easy for the other side of the flexible film strip to move too fast along the axial direction of the correction roller during the correction process, while the other side cannot move in time, which will cause wrinkles, indentations and other damages on the flexible film strip, making it waste.

[0006] In view of this, it is necessary to provide a deviation correction device for a flexible film rewinding machine. Utility Model Content
