[0020] Working principle:

[0021] During the label closing process, the label is released by the unwinding roller 2 and conveyed along the guide roller 3 to the space between the two horizontal rollers of the horizontal roller group 4. A laser beam emitted by the laser emitting device 7 is focused onto the label surface to create an easy-tear line. After the easy-tear line is created, the label is conveyed to the space between the two horizontal rollers of the horizontal roller group 5. A perforating needle wheel 8 punches vent holes in the label to facilitate venting during the subsequent closing process. The label with vent holes is conveyed towards the pressing plate 12 by the guide roller 2 11, and the sides of the label are bent inward by the guide pressure roller 9. The label is gradually folded and aligned by multiple pressing plates 12. After folding, the label is conveyed to the horizontal roller group 3 14, where glue is applied to the folded area by the glue spraying device 13, thus completing the easy-tear line creation and closing process. After closing, the label is wound up by the winding roller 16 after passing through the guide roller 3 15.

[0022] When processing bottle labels of different models, it is necessary to adjust the position of the laser emitting device 7. By pressing down the rocker arm of the limiting plate 622, the locking teeth 6221 disengage from the tooth surface of the rack 611, and the slide table 62 is pushed to slide along the linear slide rail 1, which can quickly adjust the relative position of the laser emitting device 7 in the width direction of the bottle label. After releasing the rocker arm of the limiting plate 622, the locking teeth 6221 and the tooth surface of the rack 611 mesh and engage with each other. By using the handwheel screw mechanism 621, the slide table 63 is slid along the linear slide rail 2, which can finely adjust the relative position of the laser emitting device 7 in the width direction of the bottle label. By using the handwheel screw mechanism 631, the slide table 64 is slid along the linear slide rail 3, which can finely adjust the relative position of the laser emitting device 7 in the bottle label conveying direction. The height of the laser emitting device 7 can be adjusted by using the handwheel screw mechanism 651, which is used to adjust the focal length of the laser emitting device 7.

[0023] Furthermore, the guide roller 9 has a conical wheel structure, and the end with the larger outer diameter of the guide roller 9 is the pressing end 91, which is the outer circumferential structure of a V-shaped inclined grinding wheel; the special structure of the guide roller 9 enables the bottle label to bend smoothly, improving the bottle label's folding processing effect.

[0024] The label-closing device disclosed in this embodiment, which has an online easy-tear line application function, focuses a laser beam emitted by a laser emitting device 7 onto the surface of the bottle label to apply an easy-tear line. After the easy-tear line is applied, the bottle label is sent between two horizontal rollers of the horizontal roller group 5. A perforating needle wheel 8 punches vent holes in the bottle label to facilitate venting during the subsequent label-closing process. The label is then closed by a guide pressure roller 9, a pressing plate 12, and a glue spraying device 13. This completes the label easy-tear line application and label-closing process in one station, shortening the time required for the bottle label to close. The label production process is streamlined, improving production efficiency. It also avoids damage to bottle labels caused by traditional mechanical cutting. The laser emitting device 7 can produce finer, neater tear lines, enhancing the label's aesthetics and integrity. By pressing down on the rocker arm of the limiting plate 622, the locking teeth 6221 disengage from the tooth surface of the rack 611. Through the sliding engagement structure of the support base 61, slide table 1 62, and slide table 2 63, the relative position of the laser emitting device 7 in the bottle label width direction can be quickly and precisely adjusted, making adjustment convenient and efficient.
