Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive label production, in particular to a self-adhesive label coating mechanism. Background Art

[0002] Self-adhesive labels are a type of label widely used in various products and industries. They are characterized by having adhesive on the back and can be directly attached to the surface of an object without the need for additional adhesives.

[0003] Announcement No. CN219836721U discloses a self-adhesive coating device for label processing, comprising a box body, a coating mechanism provided inside the box body, a first bracket provided at one end of the box body, a second bracket provided at the other end of the box body, a paper placing rod for mounting a paper placing roller fixedly mounted at one end of the inner wall of the first bracket, and an anti-deflection mechanism provided at the top end of the first bracket for preventing the label from deflecting. The utility model provides an anti-deflection mechanism, wherein two anti-deflection sliding sleeves move toward or away from each other on the paper placing rod, and at the same time, the paper placing roller can be pushed toward the center of the coating roller by the anti-deflection sliding sleeves. When the two anti-deflection sliding sleeves are completely in contact with both ends of the paper placing roller, the rotation can be stopped. Since the two anti-deflection sliding sleeves move at the same speed, it can ensure that the label paper released from the paper placing roller is in a position close to the center of the coating roller, thereby preventing the label paper from approaching the edge of the coating roller and affecting the coating effect.

[0004] The above patent is aimed at the fact that in the actual use of the self-adhesive coating machine in the prior art, the paper placing wheel is generally put on the outside of the paper placing rod, and then the paper placing wheel is fixed to the paper placing rod by a fixing sleeve (generally the fixing sleeve is fixed to the paper placing rod by screws). Since the length of the paper placing wheel is determined according to the width of the label paper, generally the larger the width of the label paper, the longer the length of the paper placing wheel will be, so the position of the fixing sleeve on the paper placing rod is not fixed. Therefore, when the paper placing wheel is fixed by the fixing sleeve, it is difficult to ensure that the label paper released by the paper placing wheel is located in the center position on the coating roller, which easily causes the label paper to be too close to the edge of the coating roller and affects the coating effect of the label paper. The improvement is made. The present application provides another implementation plan for the problem raised in the above patent. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a self-adhesive label coating mechanism, which has the advantage of improving the coating effect and solves the problem that the self-adhesive coating machine in the prior art is generally put on the outside of the paper putting rod, and then fixed to the paper putting rod by a fixing sleeve (generally the fixing sleeve is fixed to the paper putting rod by screws). Since the length of the paper putting wheel is determined according to the width of the label paper, generally the larger the width of the label paper, the longer the paper putting wheel will be, so the position of the fixing sleeve on the paper putting rod is not fixed. Therefore, when the paper putting wheel is fixed by the fixing sleeve, it is difficult to ensure that the label paper put out by the paper putting wheel is located in the center position on the coating roller, which easily causes the label paper to be too close to the edge of the coating roller and affects the label paper coating effect.
