DETAILED DESCRIPTION

[0021] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Please refer to Figure 2 A water-based adhesive bottomless paper coating device comprises a coating machine body 1, the coating machine body 1 comprises a guide roller 2 and an anilox roller 3, the guide roller 2 is mounted on the left side of the anilox roller 3, a gap for clamping paper is provided between the guide roller 2 and the anilox roller 3, a glue coating plate 4 is mounted above the guide roller 2, the glue coating plate 4 is mounted on the coating machine body 1 through a hinge and tilted toward the lower right, the lower end of the glue coating plate 4 is located above the anilox roller 3, the tilt angle of the glue coating plate 4 is between 45° and 60°, a glue connection groove 5 is mounted below the guide roller 2, the glue connection groove 5 is horizontally mounted on the coating machine body 1 through bolts, and the right end of the glue connection groove 5 is located below the anilox roller 3. By arranging the glue coating plate above the anilox roller, the glue falls from the glue coating plate onto the paper being transmitted, and then is evenly smeared by the guide roller, and a glue connection groove is provided under the guide roller to receive the excess glue for easy recycling.

[0024] like Figure 5 As shown, a single-sided opening groove 41 is provided on the left side of the upper surface of the glue-spreading plate 4, and a plurality of transverse diversion grooves 42 are provided on the right side. A downward T-shaped groove 43 is provided on the left edge of the glue-spreading plate 4, and an upward T-shaped groove 44 is provided on the right edge. In this way, the glue can enter the groove and then fall onto the paper through the diversion groove, avoiding the problem of uneven glue coating in various places of the paper.

[0025] The three gluing plates 4 are stacked one after another, and two adjacent gluing plates 4 are connected by hinges. When the paper is narrow, one gluing plate can be used, and the others can be folded together. When the paper is wide, two or three gluing plates can be unfolded and used, and it is very convenient to adjust the width of the gluing plates.

[0026] A folding bracket 6 is installed below the glue-coating plate 4, and the folding bracket 6 is a spring folding tripod. The side of the folding bracket 6 is installed on the coating machine body 1, and there are three folding brackets 6 installed in total, and the three glue-coating plates 4 are supported by the folding brackets 6 respectively. The folding bracket supports the glue-coating plate, and the bracket can also adjust the angle through the spring to change the angle of the glue-coating plate, which has a wider range of uses.

[0027] The lower end of the glue connection groove 5 is provided with a glue outlet, and the glue outlet is connected with a glue guide tube 7, and the end of the glue guide tube 7 is connected to the glue storage barrel. The glue guide tube can guide the glue in the glue connection groove into the glue storage barrel, and the glue is recycled and reused.

[0028] The glue outlet of the glue connection groove 5 is equipped with a solenoid valve 8, which is a high-viscosity solenoid valve with a model of WODE-SX5S. The solenoid valve can be opened at intervals to guide the glue to the glue guide tube, which does not require human operation and is very convenient.

[0029] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
