Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and more specifically, it relates to an adhesive coating mechanism for manufacturing self-adhesive labels. Background Technology

[0002] In the manufacturing process of self-adhesive labels, an adhesive coating process is required. After being dried in an oven, the evenly coated self-adhesive label tape exhibits a uniform adhesive layer thickness and is smoothly wound. Currently, most adhesive coating mechanisms on the market use a roller coating method, which is highly efficient but cannot guarantee the thickness of the adhesive layer, resulting in uneven coating and poor overall quality. Therefore, this utility model proposes an adhesive coating mechanism for self-adhesive label manufacturing. Utility Model Content

[0005] The present invention is further configured to include an embossing component disposed in front of the adhesive roller; the embossing component includes a smooth roller disposed above the self-adhesive label tape and a raised roller disposed below the self-adhesive label tape, wherein the roller surfaces of the raised roller and the smooth roller are both in contact with the self-adhesive label tape.

[0006] The present invention is further configured such that the fixing plate is arranged horizontally.

[0007] In summary, this utility model has the following beneficial effects:

[0008] 1. By using a uniform coating assembly located behind the coating roller, the coating thickness can be made uniform, thus improving the coating quality.

[0009] 2. By changing the position of the adjusting block within the adjusting hole, the force of the movable plate against the fixed plate is adjusted, thereby achieving the function of adjusting the thickness of the adhesive layer.

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See Figures 1 to 3As shown, the adhesive coating mechanism for manufacturing self-adhesive labels involved in this embodiment includes an adhesive trough 1 located below a self-adhesive label tape 100 that is conveyed back and forth. An adhesive coating roller 2 with its surface abutting the self-adhesive label tape is rotatably connected within the adhesive trough 1. The assembly includes a glue-spreading component located behind the adhesive coating roller 2. The glue-spreading component includes a fixed plate 3 arranged horizontally above the self-adhesive label tape 100 and a movable plate 4 located below the self-adhesive label tape 100. The glue-spreading component includes an adjusting shaft 5 rotatably connected to the adhesive trough 1. The lower end of the movable plate 4 is connected to the adjusting shaft 5, and its upper end abuts against the fixed plate 3. The adjusting shaft 5 is equipped with a follow-up, radially... An adjusting arm 6 extends outward from the glue-holding tank 1. The adjusting arm 6 has an adjusting hole 7 extending along its length. An adjusting block 8 is slidably connected inside the adjusting hole 7. The adjusting block 8 has a first spring connecting post 9. The glue-holding tank 1 has a second spring connecting post 10. A tension spring 11 connects the second spring connecting post 10 and the first spring connecting post 9. One end of the adjusting block 8 has a compression spring 12 located inside the adjusting hole, and the other end has an adjusting screw 13 threadedly connected to the adjusting arm. One end of the adjusting screw 13 abuts against the adjusting block 8, and the other end has a rotating part 131 located outside the adjusting hole 7.

[0018] In this embodiment, the self-adhesive label tape 100, which is conveyed back and forth, passes through the fixed plate 3 and the movable plate 4. The fixed plate 3 is located above the self-adhesive label tape 100, and the movable plate 4 is located below the self-adhesive label tape 100. Due to the tension of the tension spring 11, the movable plate 4 swings upward and continuously presses against the self-adhesive label tape 100 between the fixed plate 3 and the movable plate 4, scraping off the excess adhesive on the self-adhesive label tape 100 and performing a uniform adhesive treatment.

[0019] By rotating the adjusting screw 13 clockwise, the adjusting block 8 can be moved outward within the adjusting hole 7, causing the tension spring 11 to be stretched, increasing the tension, and consequently increasing the force of the movable plate 4 against the self-adhesive label tape 100, thus reducing the thickness of the adhesive layer after scraping. By rotating the adjusting screw 13 counterclockwise, the adjusting block 8 can be moved inward within the adjusting hole 7, causing the tension spring 11 to be shortened appropriately, reducing the tension, and consequently reducing the force of the movable plate 4 against the self-adhesive label tape 100, thus increasing the thickness of the adhesive layer after scraping.

[0020] The scraped-off adhesive can flow down with the movable plate 4 and be recycled into the adhesive collection tank 1.

[0021] The compression spring 12 is used to reset the adjusting block 8.

[0022] Example 2

[0023] See Figures 1 to 3As shown, the adhesive coating mechanism for manufacturing self-adhesive labels involved in this embodiment is further configured, based on embodiment 1, to include an embossing assembly disposed in front of the adhesive coating roller 2; the embossing assembly includes a smooth roller 14 disposed above the self-adhesive label tape 100 and a raised roller 15 disposed below the self-adhesive label tape 100, the roller surfaces of the raised roller 15 and the smooth roller 14 are both in contact with the self-adhesive label tape 100.

[0024] In this embodiment, by setting up the smooth roller 14 and the embossed roller 15 that are conveyed along with the self-adhesive label tape 100, the embossed roller 15 can emboss the adhesive surface of the self-adhesive label tape 100 during the rolling process, thereby increasing the roughness and thus making the adhesive adhesion stronger.

[0025] The adhesive coating mechanism for self-adhesive label manufacturing disclosed in this utility model can achieve uniform adhesive layer thickness and improve coating quality by using a uniform adhesive component located behind the adhesive roller; by changing the position of the adjusting block in the adjusting hole, the force of the movable plate against the fixed plate can be adjusted, thereby realizing the function of adjusting the adhesive layer thickness; and by setting the embossing component, the roughness of the adhesive surface of the self-adhesive label tape is increased, resulting in higher adhesive adhesion. The overall function is complete and highly practical.
