The glue outlet end opening of the overflow pipe 433 is higher than the glue inlet end opening of the overflow pipe 433, preferably, the overflow pipe 433 is lapped on the side wall of the glue collecting box 434, and the glue outlet of the overflow pipe 433 is located in the glue collecting box 434. The highest point of the overflow pipe 433 is higher than the lower end surface of the first glue box 411.

The setting of overflow pipe 433 has restricted the height of glue water level in first glue box 411 to avoid glue in the first glue box 411 too much and spill over outside first glue box 411, and overflow pipe 433 lies in the lower terminal surface of first glue box 411 with the intercommunication position of first glue box 411, thereby makes the glue of first glue box 411 bottom flow all the time, thereby avoids the glue concentration of first glue box 411 bottom inhomogeneous.

The glue collecting box 434 is provided with a glue feeding pipe 431. The lower end opening of the rubber feeding pipe 431 extends into the rubber collecting tank 434, and the upper end opening of the rubber feeding pipe 431 extends into the feeding barrel 422. The rubber delivery pipe 431 is provided with a liquid pump 432, and the liquid pump 432 is fixedly connected with a rubber collection tank 434. The liquid pump 432 is activated to cause the glue in the first glue cartridge 411 to be delivered into the filler barrel 422 through the glue delivery pipe 431.

The implementation principle of the embodiment is as follows:

the glue in the adding barrel 422 continuously falls into the second glue box 421, so that the glue in the second glue box 421 continuously overflows, one part of the overflowed glue falls on the second painting roller 321, the other part of the overflowed glue falls into the first glue box 411 for the first painting roller 311 to pick up, the glue in the first glue box 411 flows into the glue collecting box 434 through the overflow pipe 433, and the liquid pump 432 is started to convey the glue in the first glue box 411 into the adding barrel 422 through the glue conveying pipe 431, so that the continuous circulation of the glue is realized;

the first brushing rotary roller 311 and the second brushing rotary roller 321 are respectively abutted against two sides of the honeycomb paper core c, the first brushing rotary roller 311 and the second brushing rotary roller 321 rotate to glue the honeycomb paper core c and simultaneously drive the honeycomb paper core c to move forwards, after the honeycomb paper core c coated with glue leaves the first brushing rotary roller 311, the honeycomb paper core c firstly passes through the upper part of the first laminating rotary roller 212 to be attached to the first surface paper a under the action of the first laminating rotary roller 212, and then passes through the lower part of the second laminating rotary roller 222 to be attached to the second surface paper b under the action of the second laminating rotary roller 222, so that a finished honeycomb paperboard is obtained.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
