[0035] The release paper 10 and the working edge 34 of the label stripping plate 3 are in sliding abutment, and the effective separation of the label 12 and the release paper 10 at the working edge 34 is realized by combining the angle control of the taut release paper 10 and the label stripping plate 3.

[0036] The drive machine 13 drives the reel 14 to rotate, thereby moving the release paper 10 and realizing the continuity of the labeling process.

[0037] The labeling machine is simple and reliable in structure, and can also ensure the peeling and pasting effects of the label 12.

[0038] The limiting piece 4 can limit the release paper 10, so that the label 12 can be reliably separated from the release paper 10 at the working edge 34.

[0039] The light axis one 16 and the light axis two 17 can limit the release paper 10, and the distance of the release paper 10 on the sleeve 11 to the working edge 34 is increased, so that the release paper 10 and the label 12 can be flattened, and wrinkles of the release paper 10 and the label 12 are avoided, thereby avoiding affecting the subsequent separation of the label 12 and the winding of the release paper 10.

[0040] The detection assembly is designed, so that when the release paper 10 with the label 12 passes through the gap between the two limiting plates 24, the thickness sensor 25 can detect the label 12 and the release paper 10 in real time.

[0041] The connecting piece 21, the limiting plate 24 and the thickness sensor 25 can be adjusted in the length direction of the long hole, so as to ensure the detection effect of the thickness sensor 25.

[0042] By designing the supporting plate 18 and the blocking ring 19, the release paper 10 can reliably slide against the optical axis 1 6 and the optical axis 2 17;

[0043] By designing the compacting assembly, after the label 12 is separated from the release paper 10, the user can control the machine body 1 to make the compression roller 30 roll on the pasted label 12, thereby compacting the label 12 and ensuring that the label 12 will not be separated from the target surface;

[0044] By designing the connecting shaft 27, the connecting rod 28, the tension spring 1 29, the blocking plate 1 31, and the opposite type photoelectric sensor 32, when the compression roller 30 is pressed, the blocking plate 1 31 acts and blocks between the emitting end and the receiving end of the opposite type photoelectric sensor 32, at which time the driving machine 13 can immediately stop to prevent the compression roller 30 from moving during the compacting of the label 12;

[0045] By designing the elastic compression rod 15, the release paper 10 can be reliably wound on the reel 14;

[0046] By designing the blocking plate 2 6, the elastic ring 7, the bolt 8, and the tension spring 2 9, on the one hand, the blocking plate 2 6 cannot easily be separated from the mounting shaft 5, and on the other hand, the sleeve 1 1 and the multiple turns of the release paper 10 wound on the sleeve 1 1 cannot be separated from the mounting shaft 5, and the release paper 10 cannot be scattered.
