[0031] The working principle of this utility model is as follows: In the actual wood processing, when it is necessary to apply glue to the wood, the wood can be placed on the conveying mechanism and conveyed by the conveying mechanism. Then the wood reaches the bottom of the first gantry 7, and the glue guiding component is operated so that the glue guiding component drips water onto the wood through the glue application component. At the same time, the reciprocating component drives the glue application component to reciprocate, so that the glue drips more evenly. Then the wood is conveyed to the bottom of the second gantry 5, and the glue on the wood is scraped flat by the upper smoothing component, and the excess glue on the side of the wood is scraped off by the side smoothing component.

[0032] Furthermore, the conveying mechanism includes a machine base 13, conveying rollers 11, a transmission assembly 10, and a first rotation drive 9.

The bottom of the first gantry 7 is fixedly connected to one side of the machine base 13, and the bottom of the second gantry 5 is fixedly connected to the other side of the second gantry 5.

[0033] As can be seen from the above description, it is advantageous to operate the first rotating drive 9 when it is necessary to transport wood, so that the first rotating drive 9 drives multiple conveying rollers 11 to rotate on the machine base 13 through the transmission assembly 10, and transports wood through the rotating conveying rollers 11.

All glue-dispensing nozzles 23 are connected to the glue-flowing cavity. The connecting pipe 18 is connected to the glue-dispensing box 22, and the glue-flowing cavity is connected to the connecting pipe 18.

[0039] As can be seen from the above description, it is beneficial that after the glue enters the glue dispensing chamber in the glue dispensing box 22, the glue drips onto the wood through the glue dispensing nozzle 23.

When the wood passes by, the side scraper 3 scrapes off the excess glue on the side of the wood.

[0046] Furthermore, it also includes a support frame 12, which is fixedly connected to the lower surface of the machine base 13.

[0047] As can be seen from the above description, it is beneficial to support the entire device through the support frame 12.
