Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides an unwinding device for a rewinder, including a bottom plate 1, a mounting frame 2 is fixed to the top end of the bottom plate 1, a mounting disc 4 is rotatably connected to the inner cavity of the mounting frame 2, a motor 3 is fixed to the side wall of the mounting disc 4, a first positioning ring 5 is fixed to the side end of the mounting disc 4, a transmission rod 6 is movably connected to the inner cavity of the mounting disc 4, and a fixing structure 7 is fixed to the side end of the transmission rod 6.

[0024] Adopting the above solution: By rotatably connecting the mounting disc 4 to the inner wall of the mounting frame 2 and connecting the output end of the motor 3 to the side wall of the mounting disc 4, starting the motor 3, the motor 3 can drive the mounting disc 4 to rotate, so as to drive the product to be unwound placed on the device to rotate for unwinding operation.

[0025] The fixed structure 7 includes a rotating inner ring 701, a rotating groove 702, and a positioning block 703. The rotating inner ring 701 is fixed to the side end of the transmission rod 6. Three groups of rotating grooves 702 are formed on the outer wall of the rotating inner ring 701. The rotating grooves 702 are arranged in three groups on the outer wall of the rotating inner ring 701. The shape of the rotating groove 702 is arc-shaped. The positioning block 703 is slidably connected to the inner cavity of the rotating groove 702. The inner cavity of the rotating groove 702 is slidably connected with the positioning block 703. The top end of the positioning block 703 is fixedly connected with a limiting column 704. A second positioning ring 709 is arranged on the outer wall of the limiting column 704. Three holes are arranged on the outer wall of the second positioning ring 709. Three groups of limiting columns 704 are slidably connected with the holes arranged on the outer wall of the second positioning ring 709. A flange plate 705 is fixedly connected to the side wall of the second positioning ring 709. A connecting rod 706 is fixed to the side wall of the rotating inner ring 701. A handwheel 707 is installed on the side wall of the connecting rod 706. Two groups of fixing bolts 708 are arranged at the front and rear ends of the flange plate 705. Two groups of fixing bolts 708 are threadedly connected to the front and rear ends of the flange plate 705. The fixing bolts 708 are symmetrically distributed along the central axis of the flange plate 705.

[0026] Adopting the above solution: By providing components such as the first positioning ring 5, the rotating inner ring 701, the rotating groove 702, the positioning block 703, and the second positioning ring 709, after the user sleeved the product to be unreeled on the outer walls of the first positioning ring 5 and the second positioning ring 709, rotating the handwheel 707 can drive the connecting rod 706 to rotate, thereby driving the position of the rotating inner ring 701 to rotate. During rotation, the rotating groove 702 provided on the surface of the rotating inner ring 701 can drive the position of the positioning block 703 and the limiting column 704 on the positioning block 703 to move. Since the second positioning ring 709 can limit the limiting column 704 on the positioning block 703, it can ensure that when the rotating inner ring 701 rotates, the limiting column 704 can be telescoped through the groove of the second positioning ring 709. Furthermore, the limiting column 704 contacts the inner wall of the product to be unreeled, and the product can be fixed by the three groups of limiting columns 704. The same components are arranged on the inner wall of the first positioning ring 5. When the user rotates the rotating inner ring 701 by using the handwheel 707, the same components inside the first positioning ring 5 can be driven to rotate by the transmission rod 6 fixed on the other side of the rotating inner ring 701, so that the inner walls of the product to be unreeled can be fixed from two lengths, ensuring sufficient fixing strength and facilitating the use of the device. After rotating the handwheel 707 to an appropriate angle, by moving the two fixing bolts 708 fixed on the flange plate 705, the handwheel 707 can be fixed in the current position, ensuring the stability of the subsequent unreeling of the product to be unreeled.

[0027] A first rotating shaft 8 is fixed to the side wall of the mounting bracket 2. A first rotating rod 9 is rotatably connected to the inner cavity of the first rotating shaft 8. A second rotating shaft 10 is fixed to the side wall of the mounting bracket 2. A second rotating rod 11 is rotatably connected to the inner cavity of the second rotating shaft 10. A winding reel 12 is sleeved on the outer wall of the first positioning ring 5. The first rotating shaft 8 is fixed to the side wall of the mounting bracket 2, and the second rotating shaft 10 is fixed to the side wall of the mounting bracket 2. The first rotating shaft 8 and the second rotating shaft 10 are symmetrically distributed about the central axis of the mounting bracket 2.

[0028] Adopting the above scheme: By providing the first rotating shaft 8, the first rotating rod 9, the second rotating shaft 10 and the second rotating rod 11 on the side wall of the mounting bracket 2, it can be ensured that after the product to be unwound is placed on the device by the user, if the unwinding angle is too large, the product to be unwound will fall to the ground, affecting the functionality of the product. The first rotating shaft 8, the first rotating rod 9, the second rotating shaft 10 and the second rotating rod 11 can lift the remaining product to prevent contamination.

[0029] The working principle and usage process of the present utility model: By rotatably connecting the mounting disc 4 to the inner wall of the mounting bracket 2 and connecting the output end of the motor 3 to the side wall of the mounting disc 4, starting the motor 3, the motor 3 can drive the mounting disc 4 to rotate, so as to drive the product to be unwound placed on the device to rotate for unwinding operation. By providing components such as the first positioning ring 5, the rotating inner ring 701, the rotating groove 702, the positioning block 703 and the second positioning ring 709, after the user sleeved the product to be unwound on the outer walls of the first positioning ring 5 and the second positioning ring 709, rotating the handwheel 707 can drive the connecting rod 706 to rotate, thereby driving the position of the rotating inner ring 701 to rotate. When rotating, the position of the positioning block 703 and the limiting column 704 on the positioning block 703 can be driven through the rotating groove 702 provided on the surface of the rotating inner ring 701. Since the second positioning ring 709 can limit the limiting column 704 on the positioning block 703, it can ensure that when the rotating inner ring 701 rotates, the limiting column 704 is telescoped through the groove of the second positioning ring 709, and then the limiting column 704 contacts the inner wall of the product to be unwound, and the three limiting columns 704 can fix it.
