Axial automatic limiting tube winding machine driven by friction

The invention belongs to manufacturing of tube-winding type heat exchanger in chemical industry, and particularly relates to an axial automatic limiting tube winding machine driven by friction used for winding heat exchange tubes for a wound tube body which is one internal part of the tube-winding type heat exchanger. The axial automatic limiting tube winding machine driven by friction comprises a driving supporting device and an adjusting and supporting device for displacement. The driving supporting device comprises a driving supporting beam guide rail, a driving supporting beam movably arranged on the driving supporting beam guide rail and driving supporting roll devices arranged on the driving supporting beam. The driving supporting beam guide rail is arranged in the axial direction of the driving supporting roll devices. The two driving supporting roll devices are driven through a motor. The adjusting and supporting device for displacement comprises a driven supporting beam guide rail, a driven supporting beam movably arranged on the driven supporting beam guide rail and driven supporting roll devices which are movably arranged on the driven supporting beam and can slide symmetrically on the driven supporting beams. The driving supporting guide rail and the driven supporting guide rail are perpendicular with each other. The axial automatic limiting tube winding machine driven by friction has the advantages of being simple in structure, convenient to operate, safe and stable.
