DETAILED DESCRIPTION

[0027] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0028] like Figure 1-Figure 4 As shown, a labeling device of the utility model includes a label placing component, a substrate 2, and a label feeding component, a label peeling component, a bottom paper recycling component, a traction component 3 and a pressing component 4 installed on the substrate 2. Figure 5-Figure 10 As shown, the traction assembly includes a traction seat 31, and two limit plates 32 and a traction wheel 33 installed on the traction seat 31. A mounting block for mounting the two limit plates 32 and the traction wheel 33 is integrally formed on one side of the top of the traction seat 31. The two limit plates 32 are symmetrically arranged close to the side of the traction seat 31, and a gap is provided between the limit plates 32 and the traction wheel 33 for the label to pass through; Figure 9-10 As shown, the clamping assembly 4 includes a clamping seat 41, a clamping wheel 42, a telescopic clamping block 43, an adjusting shaft and an adjusting block 44. The clamping assembly 4 is in the shape of a triangular column as a whole. The clamping seat 41 is provided with a cavity for installing the telescopic clamping block 43 and the adjusting shaft. The telescopic clamping block 43 is in an arc-shaped structure and is slidably installed in the cavity of the clamping seat 41. The cross-section of the adjusting shaft is special-shaped, so that when different faces and points of the adjusting shaft are against the back of the telescopic clamping block, the telescopic clamping block will be displaced; the adjusting shaft is installed in the cavity of the clamping seat, and the top end passes through the top surface of the clamping seat and the adjusting block in turn, and a locking bolt is threadedly connected. The adjusting shaft is close to the side of the telescopic clamping block and is against the back of the telescopic clamping block. The telescopic adjustment of the telescopic clamping block is realized by rotating the adjusting shaft through the adjusting block, thereby realizing the clamping operation of the label belt and ensuring the stable transportation of the label belt. In this embodiment, the inner diameter of the telescopic pressing block is matched with the outer diameter of the pressing wheel, and the distance between the telescopic pressing block and the pressing wheel can be adjusted by rotating the adjusting shaft of the adjusting block, thereby adapting to label papers of different thicknesses.

[0029] In this embodiment, the label placing assembly includes a label placing roller 1 and a first transmission roller shaft 5. The label feeding assembly includes a first feeding roller group 6, a second feeding roller shaft group 7, and a label placing sensing mechanism 8 installed between the first feeding roller group 6 and the second feeding roller shaft group 7. The label placing sensing mechanism 8 is used to locate the position of each label and complete the label counting at the same time. The label stripping assembly includes a guide roller 9, a labeling roller 10, a label stripping plate 11, and a U-shaped label folding block 12 installed on the label stripping plate. The label folding block 12 is installed with a label detection electric eye for detecting whether there is a label on the base paper, thereby realizing the monitoring of missing labels. The base paper recovery assembly includes a label receiving roller 13 and a label receiving guide roller 14. The number of the clamping assemblies 4 is 2, which are cross-symmetrically installed on both sides of the traction assembly 3, wherein the traction assembly 3 and one clamping assembly 4 are installed between the label feeding assembly and the label stripping assembly, and the other clamping assembly 4 is installed between the label stripping assembly and the base paper recovery assembly. When this specific implementation is used, the label tape extends from the label placing roller 1 and passes under a first transmission roller 5. After passing under another first transmission roller 5, it passes under the first feeding roller group 6 and the second feeding roller group 7 in sequence, then passes through the traction assembly 3, passes through the traction wheel 33, passes through a clamping assembly 4, passes through the guide roller 9 close to the stripping plate 11, passes over the stripping plate 11, and then turns back under the stripping plate after passing the stripping end of the stripping plate 11, passes under the stripping plate, passes through the labeling roller 10, passes through another clamping assembly 4, passes through the label receiving guide roller 14, and enters the label receiving roller 13. At this time, the label tape is in a tensioned state.

[0030] In this embodiment, a lifting adjustment mechanism 15 for adjusting the height of the substrate is also included, and the lifting adjustment mechanism can drive the substrate 1 to move up and down. It also includes a horizontal movement mechanism 16 for adjusting the distance between the substrate and the label placement component and an angle adjustment mechanism 17 for adjusting the horizontal relative angle between the label placement component and the substrate. Specifically, the lifting and lowering adjustment mechanism 15 can adopt the lifting and lowering adjustment mechanism in the prior art. For example, the lifting and lowering adjustment mechanism 15 generally includes a screw nut transmission pair, a hand wheel, a guide column, etc.; the horizontal moving mechanism 16 uses a first motor to drive the first slider to move on the first slide rail, and the angle adjustment mechanism 17 includes a rotating shaft, a sleeve sleeved outside the rotating shaft and rotatable around the rotating shaft, and a locking assembly for locking the rotating shaft. One end of the rotating shaft is hinged to the first slide seat so that the rotating shaft can swing around the first slide rail (not more than 30°), and the support frame is fixed on the sleeve. The angle adjustment mechanism uses a second motor to drive the rotation of the rotating shaft and the sleeve. The lifting and lowering adjustment mechanism uses a third motor to drive the screw nut transmission pair, the hand wheel, the guide column, etc. The first motor, the second motor and the third motor are electrically connected to the controller, and are equipped with information collection devices such as photography to collect appearance information of the object to be labeled, and the collected information is fed back to the controller. The controller controls the operation of the first motor, the second motor and the third motor after data processing to achieve precise control of the labeling position.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
