Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1 to 8 As shown, a corrugated paper uniform coating device in one embodiment of the present invention includes: a supporting side plate 1, a coating structure 2, and a glue replenishing mechanism 3.

[0033] like Figures 1 to 2 As shown, multiple evenly distributed auxiliary rollers 101 are installed on the support side plate 1 to assist in conveying corrugated paper. Multiple evenly distributed driven rotating teeth 103 are installed at both ends of one of the auxiliary rollers 101 to assist in driving the auxiliary roller 101 to rotate. Multiple support legs 102 are fixed below the support side plate 1 to support the support side plate 1, providing support for the entire device, thereby ensuring the stability of the corrugated paper conveying, preventing tilting, and ensuring uniform glue application to the corrugated paper.

[0034] like Figures 1 to 6As shown, the glue application structure 2 is installed on the support side plate 1. The glue application structure 2 includes a glue application roller 201 for applying glue to the corrugated paper. Both ends of the glue application roller 201 are fixedly connected to support side rods 202 to support the glue application roller 201, making it less likely to fall off and easier to rotate. A pair of glue-spreading arc plates 203 are provided on one side of the glue application roller 201. A connecting bent rod 204 is fixedly connected to the glue-spreading arc plate 203. The pair of support side rods 202 and the connecting bent rod 204 are rotatably connected to the support side plate 1. Guided by the glue-spreading arc plate 203, the glue on the glue application roller 201 can be evenly applied to the corrugated paper.

[0035] like Figures 1 to 5 As shown, each of the pair of support side rods 202 is equipped with a drive gear 205. The drive gears 205 mesh with the driven rotating gear 103, and the drive gears 205 can drive the driven rotating gear 103 to rotate, thereby enabling the glue applicator roller 201 and the auxiliary roller 101 to rotate synchronously and in opposite directions, facilitating the movement of the corrugated paper. A fixed bearing 206 is fixedly connected between the support side rod 202 and the support side plate 1, so that the rotation of the support side rod 202 is not easily affected.

[0036] like Figures 1 to 8 As shown, a drive rod 207 is fixedly connected to a pair of connecting bent rods 204, which is used to drive the connecting bent rods 204 and the glue-spreading arc plate 203 to rotate, so that when glue spreading is not required, the glue-spreading arc plate 203 will not affect the glue on the glue-spreading roller 201. A hexagonal connecting block 208 is fixedly connected to one end of the drive rod 207 to facilitate the rotation of the drive rod 207.

[0037] like Figures 1 to 8 As shown, the drive rod 207 is equipped with multiple evenly distributed first limiting racks 209, which are used to limit and fix the drive rod 207 through the fixing sleeve 210, the outer fixing rack 211, and the inner fixing rack 212, preventing the drive rod 207 from rotating, thereby ensuring that the glue-spreading arc plate 203 and the connecting bent rod 204 are not easily rotated. The drive rod 207 is fitted with a fixing sleeve 210, and multiple evenly distributed outer fixing racks 211 and inner fixing racks 212 are respectively installed on the inner and outer rings of the fixing sleeve 210, for limiting and fixing the drive rod 207. A groove is carved in the support side plate 1, and multiple evenly distributed second limiting racks 213 are installed on the side wall of the groove to assist in fixing the drive rod 207.

[0038] like Figures 1 to 4As shown, the glue replenishing mechanism 3 is installed above the glue applicator 201. The glue replenishing mechanism 3 includes a storage frame 301 for storing glue, thereby facilitating quick and easy glue replenishment of the glue applicator 201. Multiple lifting rods 302 are inserted into the storage frame 301. A fixing frame 303 is fixedly connected to one end of the multiple lifting rods 302 outside the storage frame 301. Multiple glue-spreading strips 304 and multiple through holes 305 are installed on the side of the fixing frame 303 near the glue applicator 201 for dispersing and evenly conveying glue into the glue applicator 201.

[0039] like Figures 1 to 4 As shown, a pair of push cylinders 306 are installed on the storage frame 301. A piston rod 307 is installed on the push cylinder 306. The other end of the piston rod 307 is fixedly connected to the fixed frame 303. It is used to control the lifting and lowering movement of the fixed frame 303 and the glue strip 304, so as to facilitate the glue application roller 201 to replenish glue, so as to continuously apply glue to the corrugated paper and improve production efficiency.

[0040] like Figures 1 to 4 As shown, multiple shrink sleeves 308 are fixed inside the storage frame 301 to seal the delivery through hole 310, thus preventing glue leakage when the glue applicator 201 does not need to be replenished. One end of the lifting rod 302 located inside the storage frame 301 is inserted into the shrink sleeve 308. A support spring 309 is fixedly connected between the lifting rod 302 and the shrink sleeve 308 to assist in pulling the lifting rod 302 back to its original position, thereby preventing the fixed frame 303 and the multiple glue applicator strips 304 from shaking and reducing glue splashing.

[0041] Specifically, the lifting rod 302 has multiple conveying holes 310 at one end inside the storage frame 301, which are used to convey the glue in the storage frame 301 to the fixed frame 303, thereby realizing the glue application roller 201.

[0042] In practical use, a pair of top-push cylinders 306 control the extension of the piston rod 307, thereby driving the fixed frame 303 and the glue-spreading strip 304 to move downward, so that the glue-spreading strip 304 is attached to the surface of the glue-spreading roller 201. The descent of the fixed frame 303 will also drive the lifting rod 302 to move downward, so that the conveying through hole 310 can be gradually exposed. At this time, the glue stored in the frame 301 can be conveyed into the fixed frame 303 through the conveying through hole 310, and then flow from the through hole 305 to the surface of the glue-spreading roller 201. Driving the glue-spreading roller 201 to rotate can achieve glue replenishment.

[0043] The corrugated paper is conveyed by multiple auxiliary rollers 101, moving it between the auxiliary rollers 101 and the glue applicator 201. At this point, the glue applicator 201 can apply glue to the corrugated paper, while the glue-equalizing arc plate 203 can guide the glue from both ends of the glue applicator 201 to the middle, thereby improving the glue application effect on the corrugated paper.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
