Compared with traditional labels, it has the advantages of not requiring glue brushing, paste, dipping in water, being pollution-free, saving labeling time, etc. It is convenient and fast to use and is widely used in daily chemical industry, medicine, electronics, logistics, food and other industries. During the processing of adhesive labels, glue needs to be coated on the back of the labels.

[0003] For example, the utility model with the application number CN202123063982.3 discloses a glue coating device for adhesive labels. The beneficial effects of this utility model are: it can position and limit labels with different widths, prevent the labels from shifting during the coating process, and avoid the printed label patterns from shifting and affecting the use. However, as the glue coating progresses in the existing coating device, the amount of glue decreases, which easily leads to less glue sticking to the glue roller, resulting in less glue on the surface of the adhesive label.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an automatic adhesive label gluing device is provided. Content of the Utility Model

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 As shown, the automatic gluing device for self-adhesive labels includes a glue box 1 and an adjustment component 3. A glue roller 2 is installed on the inner side of the glue box 1. A back plate 10 is installed on the rear side of the glue box 1. Feed rods 11 are installed on both sides of the surface of the back plate 10. The feed rods 11 cooperate with the tensioning rods 7 to transport and gluing the self-adhesive labels, and two feed rods 11 are symmetrically arranged about the vertical center axis of the back plate 10. An auxiliary component 12 is installed on the side of the exhaust fan 8, and the auxiliary component 12 includes a dust extraction pipe 1201 and a dust extraction box 1 202, and the end of the dust extraction tube 1201 is connected to a dust extraction box 1202, which can absorb dust and other impurities on the surface of the self-adhesive label to make it better glued, and the auxiliary component 12 also includes a dust suction hole 1203 and a brush piece 1204. The dust extraction hole 1203 is opened on the surface of the dust extraction box 1202, and a brush piece 1204 is installed inside the dust extraction box 1202. The brush piece 1204 has the function of brushing away the dust on the surface of the self-adhesive label, thereby increasing the cleaning effect.

[0023] like Figure 2 As shown, an adjustment component 3 for preventing the amount of glue from decreasing and affecting the gluing effect is arranged inside the glue box 1, and the adjustment component 3 includes an adjustment plate 301, a connecting block 302, an adjustment rod 303, an adjustment block 304 and a double-threaded screw rod 305. The lower end of the adjustment plate 301 is installed with a connecting block 302. The adjustment plate 301 moves upward in the glue box 1 as the amount of glue decreases, so that the glue roller 2 and the glue continue to have good contact, so that the gluing effect of the self-adhesive label is maintained, and the two ends of the connecting block 302 are installed with adjustment rods 303 through a rotating shaft. The end of the adjustment rod 303 is connected to the adjustment block 304 through a rotating shaft, and a double-threaded screw rod 305 is arranged inside the adjustment block 304. After being driven by a motor, the double-threaded screw rod 305 rotates so that the adjustment blocks 304 on both sides are close to each other, so that the adjustment rod 303 rotates to change the tilt angle. At this time, the adjustment rod 303 supports and moves the adjustment plate 301, providing adjustment power for the adjustment plate 301.

[0024] like Figure 3 As shown in the figure, a mounting plate 4 is installed in the middle of the back plate 10. A hydraulic rod 5 is installed at the lower end of the mounting plate 4. The telescopic movement of the hydraulic rod 5 causes the mounting frame 6 and the tensioning rod 7 to move, so that the tensioning rod 7 presses down and tightens the self-adhesive label, avoiding wrinkles in the self-adhesive label during latex application and affecting the finished product effect. Moreover, the output end of the hydraulic rod 5 is equipped with a mounting frame 6. The shape of the mounting frame 6 is a U-shaped, and a tensioning rod 7 is installed inside the mounting frame 6. An air extractor 8 is installed at the upper end of the mounting plate 4. The air extractor 8 makes the inside of the dust extraction box 1202 have suction gas, and the top of the air extractor 8 is connected to a dust extraction box 9.

[0025] In summary, for the automatic glue coating device for self-adhesive labels, first, according to Figure 1-Figure 3 the structure shown in the figure, the self-adhesive label to be coated with glue is passed from the right feeding rod 11 to the lower side of the tensioning rod 7 and then passes outside the left feeding rod 11. Before gluing, the air extractor 8 is turned on to make the inside of the dust extraction box 1202 have suction gas. The dust extraction box 1202 can suck dust and other impurities on the surface of the self-adhesive label, making it better glued. At the same time, the brush piece 1204 brushes the dust on the surface of the self-adhesive label, enhancing the cleaning effect. When gluing, the glue coating roller 2 is driven by the motor to rotate, and the self-adhesive liquid in the glue tank 1 is roll-coated on the surface of the self-adhesive label. As the amount of glue decreases during gluing, the double-threaded screw rod 305 can be controlled to rotate driven by the motor, causing the adjusting blocks 304 on both sides to approach, making the adjusting rod 303 rotate and change the inclination angle. At this time, the adjusting rod 303 provides a jacking force for the adjusting plate 301 to move, providing adjustment power for the adjusting plate 301. At this time, the adjusting plate 301 moves upward in the glue tank 1 as the amount of glue decreases, so that the glue coating roller 2 and the glue continue to have good contact, maintaining the glue coating effect of the self-adhesive label.

[0026] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
