The utility model relates to the technical field of veneer reeling machines, and provides a roll shaft diameter adjustable thin-wall veneer reeling machine which comprises an outer shell, a rotating roll is rotatably connected to the inner side of the outer shell, a limiting structure is connected between the rotating roll and the outer shell, an adjusting roll is rotatably arranged on the inner side of the outer shell, and the adjusting roll is used for adjusting the diameter. The limiting structure comprises a limiting plate fixedly connected to the position, close to one end, of the outer surface of the rotating roller, the outer surface of the rotating roller is movably sleeved with a movable plate, a fixed plate is fixedly connected to the inner side of the outer shell, a limiting air cylinder is fixedly connected to the surface of the fixed plate, and a connecting plate is fixedly connected between the output end of the limiting air cylinder and the movable plate. The outer surface of the fixing plate is connected with a guide assembly. The guide assembly comprises a guide plate fixedly connected to the outer surface of the fixing plate. According to the technical scheme, the plate rolling machine solves the problem that when an existing plate rolling machine is used for corresponding to plates with different lengths, no limiting structure exists, and deviation is likely to happen when the plates are rolled.

This utility model relates to the field of rewinding machine technology and discloses a feeding device for an automatic rewinding machine, including a main frame. The main frame is equipped with a feeding mechanism and a winding mechanism. The feeding mechanism is located above the winding mechanism on the main frame. The feeding mechanism includes: a vertical plate; a sliding groove disposed on the vertical plate; a limiting plate located directly above the winding mechanism, with both ends sliding vertically within the sliding groove and fitting against the material body wound on the winding mechanism, used to detect the roll thickness of the material body; and a limiting sleeve that slides vertically on the vertical plate, with a height adjustment structure to limit the highest point of the limiting plate's upward sliding. This invention solves the problems of existing devices in monitoring the winding diameter, limiting the fabric roll diameter, and preventing the fabric roll from expanding and loosening after cutting.
