[0002] The bamboo incense board is a board made of phyllostachys pubescens as raw material, with a fresh smell of bamboo, and can adsorb harmful substances such as formaldehyde. When making the bamboo incense board, pure phyllostachys pubescens materials are used and processed through multiple processes, having the advantages of tough texture, wear-resistant and pressure-resistant, antibacterial and mildew-proof, etc. Compared with traditional boards, the bamboo incense board has higher environmental protection performance and longer service life, and is a new type of green material. The sizing and pressing device for bamboo incense boards is a device specially used in the production process of bamboo incense boards, and its main function is to perform sizing and pressing operations in the production process of bamboo incense boards.

[0003] The Chinese patent with the publication number CN219650142U discloses a sizing device for bamboo board processing, including a scraping structure, a moving structure is arranged on the left side of the scraping structure, a glue spraying structure is arranged on the top surface of the moving structure, and a supporting structure is arranged at the bottom of the moving structure.

[0004] The above-mentioned existing technical solutions have the following defects: Although the glue spraying structure can achieve uniform spraying of glue, if there is no subsequent pressing step, the sprayed glue may not fully play its bonding role.

[0005] Therefore, we propose a sizing and pressing device for bamboo incense boards to solve the above problems. Content of the Utility Model

The glue is transported from the storage tank 207 through the conveying pipeline 206 to the glue application spray pipe 204, and then evenly sprayed on the surface of the bamboo incense board on the first conveyor belt 3 by the glue application nozzle 205. The sprayed bamboo incense board continues to move forward and passes through the smearing component. The motor 606 drives the threaded rod 603 to rotate, so that the connecting block 604 drives the scraper 605 to move up and down. After adjusting to the appropriate height, the scraper 605 evenly spreads the glue to prevent glue accumulation. The smeared bamboo incense board enters the pressurizing unit, and the first conveyor belt 3 transports the bamboo incense board to the placement table 5. The air cylinder 801 drives the pressing plate 806 to move downward, applying uniform pressure to the bamboo incense board to ensure uniform distribution and firm adhesion of the glue. At the same time, the electric heating plate 805 heats up to accelerate the curing of the glue. The pressurized bamboo incense board is transported to the lower part of the air-drying component through the second conveyor belt 4. The wind generated by the fan 7 evenly blows on the surface of the bamboo incense board to accelerate the drying of the glue.
