[0034] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0035] In the accompanying drawings, the same reference numerals represent the same parts. It should be noted that the described embodiments are only some, not all, of the embodiments disclosed herein.

[0036] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0037] Example 1

[0038] like Figures 1 to 9 As shown, the label winding structure of this utility model includes:

[0039] A winding body 1 has at least three first shaft holes 2 radially distributed around the axis of the winding body 1 at one end, wherein at least one of the first shaft holes 2 has an oblique shaft hole 3 communicating with the first shaft hole 2 on its side; the oblique shaft hole 3 is located near the outer side; the winding body 1 has at least one through hole 4 communicating with the oblique shaft hole 3;

[0040] At least three winding connecting rods 5 are fixedly or detachably connected to at least three first shaft holes 2; wherein at least one winding connecting rod 5 has a first screw hole 6.

[0041] The first fastener 7 passes through the through hole 4 and the inclined shaft hole 3 and is threadedly connected to the first screw hole 6.

[0042] Figure 4 and Figure 6 The diagram shows a first shaft hole 2 located above a slanted shaft hole 3; the slanted shaft hole 3 communicates with the first shaft hole 2, and a through hole 4 is located above the slanted shaft hole 3; as shown. Figure 4As shown, the left end of the uppermost winding connecting rod 5 is located at the left end of the first shaft hole 2. (See Figure 2) Figure 4 When the first fastener 7 is rotated clockwise or counterclockwise, it can pull the winding connecting rod 5 to swing up and down; that is, as Figure 4 As shown, the first fastener 7 can pull the winding connecting rod 5 upward through the threaded connection, ultimately resulting in the right end of the winding connecting rod 5 being at an upward tilt angle; or the first fastener 7 can loosen the threaded connection, causing the winding connecting rod 5 to be in the position shown. Figure 3 The label is shown in a relaxed horizontal position. When the right end of the winding connecting rod 5 is at an upward tilt angle, the wound label can be tightened better during the winding process. When it is necessary to remove the wound label from the three winding connecting rods 5, simply relax the winding connecting rod 5 so that it is at a horizontal angle, and the wound label can be easily removed.

[0043] This invention achieves the function of facilitating the winding and unwinding of the wound label paper by setting a connected oblique shaft hole 3 inside the first shaft hole 2, allowing different winding connecting rods 5 to switch between an open state and a retracted state.

[0044] Further, see Figures 1 to 3 It includes a baffle 8, and the winding body 1 has a corresponding second screw hole 9 at one end connected to the winding connecting rod 5 and the baffle 8 respectively;

[0045] It includes a second fastener 10, which is threadedly connected to the second screw hole 9. Figure 4 The diagram shows that the baffle 8 and the winding body 1 are detachably connected by a second fastener 10.

[0046] Furthermore, the winding body 1 has a second shaft hole 11 at its center; the other end of the winding body 1 is provided with a magnet 12 that is fixedly connected or detachably connected.

[0047] It includes a magnetic base 13, one side of which has a fixedly connected connecting shaft 14; the magnetic base 13 is movably installed in the second shaft hole 11, and the magnetic base 13 is magnetically connected to the magnet 12. Figure 4 The connecting shaft 14 is shown to be movably inserted into the second shaft hole 11; wherein the magnetic base 13 abuts against the magnet 12 and the winding body 1 under the magnetic attraction of the magnet 12.

[0048] Furthermore, the other end of the winding body 1 has a magnetic suction hole 15, and the magnet 12 is installed in the magnetic suction hole 15.

[0049] Furthermore, each end of the winding body 1 has a countersunk hole 16, which communicates with the second shaft hole 11; a bearing 17 is installed in each of the countersunk holes 16. Figure 4 This demonstrates that when the connecting shaft 14 is installed in the second shaft hole 11, the connecting shaft 14 is simultaneously located within the bearing 17. The connecting shaft 14 has a third shaft hole 18.

[0050] Furthermore, the connecting shaft 14 has a third threaded hole 19 on its side; it also includes a third fastener 20, which is threadedly connected to the third threaded hole 19. Figure 4 This demonstrates that the third fastener 20 can move up or down via a threaded connection with the third screw hole 19, as shown. Figure 4 As shown, when the third fastener 20 moves downward, the end of the third fastener 20 abuts against the motor shaft of the motor installed in the label rewind body 21.

[0051] Example 2

[0052] like Figures 1 to 9 As shown, the label rewinding device of this utility model includes all the solutions of the label winding structure described in Embodiment 1; and also includes a label rewinding body 21. The label rewinding body 21 is the prior art, and will not be described in detail here. The difference between it and the prior art is that the motor shaft of the motor inside the label rewinding body 21 is installed in the third shaft hole 18 of the connecting shaft 14 in the label winding structure, and the motor shaft is fixedly connected to the connecting shaft 14.

[0053] This invention utilizes magnet 12 to connect the magnetic base 13 and the winding body 1. Therefore, the entire rotation of the winding body 1 and the winding connecting rod 5 is driven by the magnetic attraction of the magnet. When the external force during rotation is greater than the magnetic attraction, the magnetic base 13 can continue to rotate normally under the drive of the motor, while the winding body 1 and the winding connecting rod 5 can slip and not rotate. That is, they slip and do not rotate because the magnetic attraction is less than the external force. This improves the safety of the product while ensuring the basic rewinding force and making the overall winding secure. On the other hand, it also avoids the problem of motor overheating and aging caused by the motor not rotating under the obstruction of external force.
