Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or end comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed therein, or may optionally include other steps or elements inherent to such process, method, product, or end.

[0021] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model discloses a specific embodiment of a separation guide mechanism with a grooveless glue coating roller 11, see Figures 1 to 3 The separation guide mechanism includes a frame 1, in which a glue coating roller 11 is provided which can rotate relative to the frame 1.

[0023] In this embodiment, a first guide shaft 21 and a second guide shaft 22 are fixedly mounted in the frame 1 and located to the side of the glue coating roller 11. The first guide shaft 21 and the second guide shaft 22 are both fixed relative to the frame 1. The first guide shaft 21 and the second guide shaft 22 are spaced apart in the height direction. The two guide shafts can be staggered in the height direction or arranged on the same vertical axis.

[0024] As an improvement, the first guide shaft 21 is located above the second guide shaft 22. The outer peripheral side surface of the first guide shaft 21 is sleeved with a plurality of guide blades 3 arranged at intervals along the axial direction of the first guide shaft 21. An elastic member is provided between the second guide shaft 22 and the first guide shaft 21 to drive the guide blades 3 toward the glue coating roller 11. In other embodiments, the second guide shaft 22 can also be located above the first guide shaft 21. The specific arrangement can be selectively adjusted according to actual conditions.

[0025] Optionally, the elastic member is a spring 4. A connecting portion 32 extends downward from the bottom end of the guide plate 3. The top end of the spring 4 is sleeved on the outer peripheral side of the connecting portion 32, and the spring 4 is fixedly connected to the connecting portion 32. In addition, the outer peripheral side surface of the second guide shaft 22 is formed with a plurality of guide posts 23 that protrude outward and are arranged at intervals along the circumference of the second guide shaft 22. The bottom end of the spring 4 is sleeved on the outer peripheral side of the guide posts 23, and the spring 4 is fixedly connected to the guide posts 23. It should be noted that the fixed connection between the spring 4 and the connecting portion 32 and between the spring 4 and the guide posts 23 can be achieved by welding.

[0026] Please see Figure 3 Each guide plate 3 has a through hole 31 in the middle, through which the first guide shaft 21 passes. The diameter of the through hole 31 is larger than the outer diameter of the first guide shaft 21, ensuring that the guide plate 3 has sufficient space for movement. To prevent the guide plates 3 from wobbling, spacers 5 are positioned between adjacent guide plates 3. Each spacer 5 is fixedly mounted on the outer circumference of the first guide shaft 21, forming a groove between adjacent spacers 5 for the guide plates 3 to fit in. This groove limits the freedom of the guide plates 3 to wobble left and right, thereby ensuring the stability of the guiding operation. In other embodiments, the spacers 5 can be integrally formed with the first guide shaft 21.

[0027] Preferably, the top surface and side surface of the guide piece 3 can be set in a crescent shape. The crescent shape can better fit the roller body (glue coating roller 11, lower glue roller, etc.) in all directions and can be selectively set according to actual conditions.

[0028] It should be noted that the outer peripheral side surface of the glue coating roller 11 is a smooth curved surface. Compared with the conventional glue coating roller 11 with annular grooves, the glue coating effect is better and the glue coating is more uniform.

[0029] Compared with the prior art, the separation guide mechanism of this embodiment drives the guide piece 3 to stick to the glue coating roller 11 by setting an elastic part. Under the premise of ensuring that the guide mechanism guides the label paper normally, it can remove the annular groove previously opened on the outer peripheral side of the glue coating roller 11, so that the glue coating is more uniform, eliminates the defects such as bubbles or bulging in the label paper in the past, improves the yield rate, thereby improving work efficiency and solving the problem of low work efficiency in the past.

[0030] Finally, it should be noted that the separation guide mechanism with a grooveless glue coating roller 11 disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
