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 in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0028] An automatic labeling machine includes an automatic labeling machine body 1 and a paper feeding mechanism arranged on the automatic labeling machine. The paper feeding mechanism includes a fixed limit ring 2. A positioning sleeve 3 is fixedly connected to the center of the fixed limit ring 2. A movable limit ring 4 is slidably connected to the outer surface of the positioning sleeve 3. A label paper carrier ring 5 is sleeved on the outer surface of the positioning sleeve 3 and between the fixed limit ring 2 and the movable limit ring 4. The label paper is wound around the label paper carrier ring 5.

[0029] A central shaft 6 is fixedly connected inside the positioning sleeve 3. Grooves arranged in an annular array are formed on the outer surface of the central shaft 6. Tension springs 7 are fixedly connected in the grooves. One end of the tension spring 7 is fixedly connected to a movable pressure plate 8. One end of the movable pressure plate 8 is inclined. Transverse notches 9 arranged in an annular array are formed on the outer surface of the positioning sleeve 3. One end of the movable pressure plate 8 penetrates through the transverse notch 9 and extends to the outside of the positioning sleeve 3.

[0030] As Figure 1, the movable limiting ring 4 is one of the components of the paper preventing mechanism. The automatic labeling machine body 1 with a paper feeding mechanism is a prior art, and the automatic labeling machine body will not be elaborated here. The fixed limiting ring 2 and the movable limiting ring 3 are located at both ends of the label paper bearing ring 5, which can prevent the label paper bearing ring 5 from moving horizontally. The label paper to be labeled is wound around the label paper bearing ring 5, and when the label paper bearing ring 5 rotates, the release of the label paper can be achieved.

[0031] One end of the positioning sleeve 3 is provided with a thread, and a locking nut 10 is threadedly connected to the positioning sleeve 3 for positioning the label paper bearing ring 5 between the fixed limiting ring 2 and the movable limiting ring 4.

[0032] Such as Figure 2 and Figure 4 , the outer surface of the positioning sleeve 3 has a thread to achieve threaded connection with the locking nut 10. By using the locking nut 10, pressure is applied to the movable limiting ring 4 in the direction of the fixed limiting ring 2, and the positioning of the label paper bearing ring 5 can be achieved.

[0033] One end of the positioning sleeve 3 is provided with a rectangular groove 11. The inner surface of the movable limiting ring 4 is fixedly connected with a rectangular connecting plate 12. Inside the positioning sleeve 3 and on the rectangular connecting plate 12, an extrusion end 13 is fixedly connected. The extrusion end 13 is set as a frustum, and the extrusion end 13 abuts against the movable pressing plate 8.

[0034] Such as Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 , the curved surface part of the extrusion end 13 and the part of the movable pressing plate 8 located inside the positioning sleeve 3 are in contact with each other.

[0035] One end of the positioning sleeve 3 is provided with a closing cover 14. The inner surface of the closing cover 14 is fixedly connected with a clamping block 141, and the clamping block 141 is adapted to the rectangular groove 11.

[0036] Such as Figure 5 and Figure 6 , the clamping block 141 can just be inserted into the rectangular groove 11 to clamp the closing cover 14 at one end of the positioning sleeve 3.

[0037] An arc-shaped connecting piece 15 is fixedly connected to the movable pressing plate 8. Limiting shafts 16 are fixedly connected between the outer surface of the central shaft 6 and the inner wall of the positioning sleeve 3 and on both sides of the movable pressing plate 8. The arc-shaped connecting piece 15 is slidably connected to the limiting shafts 16.

[0038] Such as Figure 4 , Figure 5 , Figure 7 and Figure 8, the limiting shaft 16 passes through the arc-shaped connecting piece 15, so that the arc-shaped connecting piece 15 and the movable pressure plate 8 will not tilt during movement.

[0039] One end of the fixed limiting ring 2 far away from the positioning sleeve 3 is fixedly connected with a connecting pipe sleeve 17, and the connecting pipe sleeve 17 is provided with connecting holes 18 arranged in an annular array.

[0040] Such as Figure 1 , Figure 2 and Figure 3 , the connecting pipe sleeve 17 can be fixed to the corresponding mechanism on the automatic labeling machine body 1 through the assistance of the connecting holes 18, and the corresponding mechanism on the automatic labeling machine body 1 drives the connecting pipe sleeve 17 and the entire paper feeding mechanism to rotate, realizing the rotational paper feeding of the label paper bearing ring 5.

[0041] The working principle of an automatic labeling machine provided by the present utility model is as follows:

[0042] When installing the label paper bearing ring 5, the label paper bearing ring 5 is sleeved on the positioning sleeve 3 and moves towards the fixed limiting ring 2. The label paper bearing ring 5 presses the inclined surface of the movable pressure plate 8, so that the movable pressure plate 8 enters the positioning sleeve 3. Then, by using the tension of the tension spring 7, the movable pressure plate 8 presses the positioning label paper bearing ring 5 from the inner wall of the label paper bearing ring 5;

[0043] Then, the movable limiting ring 4 is sleeved on the positioning sleeve 3, and the locking nut 10 locks the movable limiting ring 4, so that the movable limiting ring 4 and the fixed limiting ring 2 squeeze and fix the positioning sleeve 3 from both ends. The movable limiting ring 4 drives the extrusion end 13 to move through the rectangular connecting plate 12, and the extrusion end 13 abuts against the movable pressure plate 8, so that the movable pressure plate 8 will not loosen the positioning of the label paper bearing ring 5.

[0044] Compared with the related technology, an automatic labeling machine provided by the present utility model has the following beneficial effects:

[0045] In the present utility model, the movable pressure plate 8 extends out from the inside of the positioning sleeve 3 and presses the positioning label paper bearing ring 5 from the inner wall. Then, the fixed limiting ring 2 and the movable limiting ring 3 position the label paper bearing ring 5 from both ends, ensuring the synchronous rotation of the label paper bearing ring 5 and the positioning sleeve 3, making the rotation speed of the paper feeding mechanism consistent with the release speed of the label paper, and avoiding the label paper from being loose due to excessive release or being torn due to insufficient release.

[0046] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed.
