A third gear rotates to be meshed with a rack so as to drive a sliding base, a connecting block and a bundling device to synchronously move, self-adaptive distance adjustment is conducted according to bundling cable coil bodies with different diameters, practicability is improved, operation is convenient and fast, and after debugging is completed, the device is convenient to operate. And then the control panel is used for simultaneously starting each group of binding devices to bind and package the binding cable coils with different diameters, so that the packaging stability of the binding cable coil body is guaranteed.

The utility model provides an unreeling device of a medicinal aluminum foil coating printing machine, which relates to the technical field of coating printing machines, and comprises a platform plate, an unreeling component for unreeling and a deviation rectifying device for deviation rectifying are arranged on the upper surface of the platform plate, the unreeling component comprises two vertical plates, a driving motor is arranged on the side surface of each vertical plate, and the deviation rectifying device is arranged on the side surface of each vertical plate. The vertical plates are connected with the platform plate in a sliding mode, and a rotating disc is rotationally connected between the two vertical plates. According to the unreeling device of the medicinal aluminum foil coating printing machine, when reel bodies of different sizes need to be replaced in the using process, a hydraulic rod drives a toothed plate to move so as to drive a vertical plate to move, an old bearing cylinder is replaced with a new bearing cylinder, and when the size of the bearing cylinder is large, a first electric push rod drives a sliding block to move, so that the reel bodies of different sizes can be replaced. And the bearing cylinder is clamped by the sliding block, so that the stability of the bearing cylinder is maintained, and the problem that a common unwinding device in the prior art is poor in applicability is solved.

The invention relates to a roll and a roll manufacturing method. A roll (1) is provided with: a winding core (2); a long first film (10) wound around the winding core (2); and a joining member (3) that joins one end of the first film (10) in the longitudinal direction to the winding core (2). The joining member (3) is disposed between the winding core (2) and one end of the first film (10) in the longitudinal direction in the thickness direction of the first film (10). Furthermore, in the radial direction of the winding body (1), the distance from the outer peripheral surface of the winding core (2) to the radial inner side surface of one end of the first film (10) in the longitudinal direction is the shortest in at least one end in the width direction with respect to the distance in the entire region in the width direction.
