[0027] The following is a specific embodiment of the present application, and the technical scheme of the present application is further described in combination with the drawings, but the present application is not limited to these embodiments.

[0028] A trademark paper glue coating device, as shown in Figure 1 , comprising a glue cylinder 1, a glue roller 2 and a glue scraping plate 3 arranged in the glue cylinder 1, and a base 31 and a pressing plate 32 for fixing the glue scraping plate 3, the glue scraping plate 3 being located between the base 31 and the pressing plate 32 and being fixed by screws passing through the pressing plate 32, the glue scraping plate 3 and the base 31 in turn, and the gap between the end of the glue scraping plate 3 and the surface of the glue roller 2 forming a glue supply gap.

[0029] In use, the glue cylinder 1 contains glue liquid at the bottom, the bottom of the glue roller 2 is immersed in the glue liquid to draw the glue liquid on its surface, and at the same time the glue roller 2 rotates clockwise, when the part drawing the glue liquid rotates to the glue scraping plate 3, the end of the glue scraping plate 3 scrapes the glue layer on the surface of the glue roller 2 and at the same time scrapes the excess glue layer with a thickness exceeding the width of the glue supply gap. It can be seen that the width of the glue supply gap affects the thickness of the glue layer on the glue roller 2 and further affects the thickness of the trademark paper coated by the glue roller 2, so when in use, the width of the glue supply gap needs to be adjusted to be suitable for different specifications of trademark paper.

[0030] In this application, in order to adjust the width of the glue supply gap between the end of the glue scraping plate 3 and the glue roller 2, a glue amount adjusting block 33 is further included. As shown in Figure 2 , the glue amount adjusting block 33 is wedge-shaped, including an abutting surface 331 abutting with the cylinder wall of the glue cylinder 1, the abutting surface 331 being parallel to the cylinder wall of the glue cylinder 1 and being able to completely fit, generally being a vertical surface; further including an adjusting surface 332 opposite to the abutting surface 331, the adjusting surface 332 being an inclined surface, the distance from the adjusting surface 332 to the abutting surface 331 decreasing from top to bottom along the vertical direction, and at the same time the adjusting surface 332 abutting with the other end of the glue scraping plate 3 opposite to the end for scraping glue. Figure 2 and Figure 3 When the glue amount adjusting block 33 moves vertically downward close to the cylinder wall of the glue cylinder 1, the width of the part between the glue scraping plate 3 and the cylinder wall of the glue cylinder 1 increases, thereby pushing the glue scraping plate 3 to move on the base 31 in the direction away from the cylinder wall of the glue cylinder 1, thereby reducing the width of the glue supply gap between the glue scraping plate 3 and the glue roller 2, so as to reduce the thickness of the glue layer on the glue roller 2.

[0031] In some embodiments, since the glue amount adjusting block 33 is only installed between the glue scraping plate 3 and the cylinder wall of the glue cylinder 1 by abutment, there can be instability problems. Therefore, the glue amount adjusting block 33 can be in abutment with the pressing plate 32 or directly connected with the pressing plate 32, and the glue amount adjusting block 33 can be further fixed by the fixed pressing plate 32.

[0032] For example, in some embodiments, the glue amount adjusting block 33 and the pressing plate 32 are separate, and the glue amount adjusting block 33 is in abutment with the pressing plate 32. During adjustment, the screw can be loosened, the pressing of the pressing plate 32 on the glue scraping plate 3 can be slowed down, or the pressing plate 32 can be completely removed, and then the glue scraping plate 3 is moved by the glue amount adjusting block 33. Since it is necessary to ensure the abutment of the glue amount adjusting block 33 and the pressing plate 32, and the connection of the pressing plate 32 and the glue scraping plate 3 by the screw, as shown in Figure 2 , the glue scraping plate 3 is provided with a waist-shaped hole 34 in the length direction parallel to the direction from the glue applying roller 2 to the cylinder wall of the glue cylinder 1 to adapt to the movement of the glue scraping plate 3, and the pressing plate 32 and the base 31 are respectively provided with screw holes matched with the screw.

[0033] For another example, in some embodiments, as shown in Figure 4 , the glue amount adjusting block 33 and the pressing plate 32 are integrated, and the glue amount adjusting block 33 is directly connected with the pressing plate 32. During adjustment, the pressing plate 32 can be pressed on the glue scraping plate 3 at all times, which can limit the lifting of the glue scraping plate 3, and avoid problems such as that the distance between the end of the glue scraping plate 3 and the glue applying roller 2 does not match the expectation, the glue amount does not match the expectation, the glue scraping plate 3 is not stably installed, the glue scraping plate 3 is easily shaken during the glue applying process to affect the glue applying quality, and the like. In the integrated design, since the glue amount adjusting block 33 moves the pressing plate 32, the distance between the pressing plate 32 and the glue scraping plate 3 is affected, therefore, a deformable gasket 321 is arranged between the pressing plate 32 and the glue scraping plate 3 to adapt to different distances and improve the installation strength, and the glue scraping plate 3 and the gasket 321 are respectively provided with a waist-shaped hole 34 in the length direction parallel to the direction from the glue applying roller 2 to the cylinder wall of the glue cylinder 1, and the pressing plate 32 and the base 31 are respectively provided with screw holes matched with the screw.

[0034] The pressing of the pressing plate 32 can limit the lifting of the glue scraping plate 3 during adjustment, and in some embodiments, the base 31 is provided with a limiting groove 312, and the glue scraping plate 3 is arranged in the limiting groove 312, and the two ends of the glue scraping plate 3 in the axial direction of the glue applying roller 2 are respectively in abutment with the groove walls of the limiting groove. The limiting groove 312 can limit the swinging of the glue scraping plate 3 during adjustment, thereby avoiding problems such as that the distance between each point of the end of the glue scraping plate 3 and the glue applying roller 2 is not consistent, thereby causing uneven glue amount.

[0035] In some embodiments, in order to ensure that the glue amount adjusting block 33 stably and vertically moves downward to push the glue scraping plate 3, the base 31 or / and the cylinder wall of the glue cylinder 1 is provided with a guide, and the glue amount adjusting block 33 is provided with a guide part matched with the guide.

[0036] For example, in some embodiments, as shown in Figure 2 The base 31 is provided with a vertical guide column 311, which is a guide member, and the glue amount adjusting block 33 is provided with a through hole for inserting the guide column 311, which is a guide portion. The guide column 311 guides the moving direction of the glue amount adjusting block 33. On this basis, in some embodiments, one end of the guide column 311 is rotationally connected to the base 31, and the other end forms a control end. The guide column 311 is provided with external threads. The through hole of the glue amount adjusting block 33 is provided with internal threads for threadedly connecting with the external threads of the guide column 311. In the threaded connection structure, the glue amount adjusting block 33, which cannot rotate due to abutment, can be vertically moved by rotating the guide column 311, which can improve the stability and accuracy of the moving direction of the glue amount adjusting block 33, and further maintain the stability of the glue amount adjusting block 33. In some embodiments, in order to facilitate the rotation control of the guide column 311, the control end is provided with an internal hexagonal hole, and a screwdriver is inserted to control the guide column 311.

[0037] For example, in some embodiments, the glue tank 1 is provided with a guide rail, which is a guide member, and the glue amount adjusting block 33 is provided with a sliding block for slidingly connecting with the guide rail, which is a guide portion. The guide rail guides the moving direction of the glue amount adjusting block 33.

[0038] In some embodiments, the guide column 311 and the guide rail can be provided at the same time. The guide rail and the sliding block can further limit the rotation trend of the glue amount adjusting block 33 along with the guide column 311, so as to ensure that the rotation of the guide column 311 drives the vertical movement of the glue amount adjusting block 33.

[0039] In addition, in some embodiments, as shown in Figure 5 The glue tank 1 is provided with a plurality of glue applying rollers 2, a plurality of glue scraping plates 3 corresponding to the number of the glue applying rollers 2, and a plurality of glue amount adjusting blocks 33 corresponding to the number of the glue scraping plates 3. The glue applying rollers 2 and the glue scraping plates 3 are one-to-one corresponding, and the glue scraping plates 3 and the glue amount adjusting blocks 33 are one-to-one corresponding, so that the glue applying amount of each glue applying roller 2 can be individually adjusted, and the glue applying flexibility is improved.

[0040] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
