Fig. 1 is a schematic structural view of a sheet unwinding device according to the present invention;

fig. 2 is an enlarged view of a movable portion of the sheet unwinding device.

In the figure: 1. a limiting disc; 2. a drive shaft; 3. a movable portion; 4. a motor; 5. a driven structure; 6. a driven shaft; 7. an upper roller; 8. and (5) a lower roller.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1:

referring to fig. 1-2, a sheet unwinding device comprises a driving structure, a driven structure 5, an upper roller 7 and a lower roller 8, wherein the driving structure comprises a driving shaft 2, a limiting disc 1, a motor 4 and a movable part 3, two ends of the driving shaft 2 are fixed on the unwinding device in a matching way through bearings, one end of the driving shaft 2 is connected with an output shaft of the motor 4 through a coupler, the motor 4 can be a YS904 three-phase motor and is used for driving the driving shaft 2 to rotate, the driving shaft 2 is further provided with the limiting disc 1, the limiting disc 1 can be fixed on the driving shaft 2 in a welding or other way, two ends of the movable part 3 are movably connected with the driving shaft 2 through pins as shown in fig. 2, one end of the movable part can be used as a rotating end, when a roll 9 needs to be sleeved into the movable part 3, the pin is pulled out to rotate the movable part 3 by a certain angle, and the pin is inserted, so that the structure is convenient and quick, and the operation is convenient.

The driven structure 5 consists of driven shafts 6, the driven shafts 6 are matched on the driven structure 5 through bearings, at least 3 driven shafts 6 are provided in the embodiment, when the width of the coil stock 9 is increased, the number of the driven shafts 6 can be synchronously increased, and the coil stock 9 is convenient to slide.

The lower roller 8 is fixed on a metal plate, the upper roller 7 is fixed above the lower roller 8 through the movable block, the distance between the upper roller and the lower roller 7 and the distance between the upper roller and the lower roller 8 are adjustable, and the lower roller 8 and the upper roller 7 are matched with bearings to realize rolling.
