[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The labeling and re-pressing sections are designed to facilitate label application onto cosmetic packaging. Firstly, the pressure plate, unwinding roller, and rewinding roller facilitate the application of labels. Secondly, after labeling, the cosmetic packaging moves to a position below the pressure block, which then moves downwards under the influence of a second electric cylinder. This pressure block further compresses the label area, increasing the adhesion between the label and the cosmetic packaging. This re-pressing process avoids problems of poor label adhesion and weak bonding.

[0020] 2. Through the structure of the second spring and connecting seat, when the pressure block presses on the cosmetic packaging box, the elasticity of the second spring can prevent the pressure applied by the pressure block from being too great, which could lead to deformation or damage to the cosmetic packaging, thus protecting the cosmetic packaging.

The connecting plate 22 is not rotatably connected to the ear plate 27; a connecting rod 23 is fixed at the bottom center of the connecting plate 22, and a pressure plate 24 is fixed at the bottom end of the connecting rod 23; a pressure part 3 is provided on the front side of the bracket 20, the pressure part 3 includes a fixed frame 30, two second electric cylinders 31 are fixed on the top of the fixed frame 30, a top plate 32 is fixed between the piston rod ends of the two second electric cylinders 31, a connecting seat 33 is provided below the top plate 32, two guide rods 34 are fixed on the top of the connecting seat 33, the guide rods 34 pass through the top plate 32 and are slidably connected to the top plate 32, and a second spring 35 for pressing against the connecting seat 33 is sleeved on the outside of the guide rods 34; a pressure block 36 for pressing the label is provided below the connecting seat 33.

[0035] In this embodiment, a limiting block 340 is coaxially fixed to the top end of the guide rod 34, and the diameter of the limiting block 340 is larger than the diameter of the guide rod 34. This design effectively prevents the guide rod 34 from moving excessively or falling off during operation, enhancing the stability and safety of the overall structure.

[0036] In this embodiment, the cross-sectional shape of the bracket 20 and the fixing frame 30 is U-shaped, and the bracket 20 and the fixing frame 30 are fixedly connected to the frame 1 by bolts. This design increases the strength and stability of the bracket 20 and the fixing frame 30, making the entire device more stable and reliable.

[0037] In this embodiment, the connecting rod 23 and the pressure plate 24 are integrally formed, with both ends of the pressure plate 24 being upturned. This integral forming structure increases the reliability and stability of the connection between the connecting rod 23 and the pressure plate 24, improving the overall durability and service life.
