[0028] Specifically, when the wood board to be coated contacts the glue coating roller 11, the glue coating roller 11 is stressed to drive the connecting frame 10, the driven wheel 8, and the U-shaped plate two 12 to move upward along the through groove 9, at the same time, the rotating plate 13 connected with the U-shaped plate two 12 can rotate to push the limiting frame 14 to move closer to each other, and then the middle region of the belt 7 can move closer to each other, so as to compensate for the looseness of the belt 7 caused by the upward movement of the driven wheel 8, and ensure that the belt 7 can still contact the driven wheel 8 and the driving wheel 6 in a tensioned state when the driven wheel 8 moves upward, and by the deformation of the belt 7 within a certain range and the increase of the wrap angle formed by the belt 7, the driven wheel 8 can be more reliably driven to rotate by the belt 7 when the hollow rod 5 and the driving wheel 6 are rotated by the servo motor 4, preventing slipping, and at the same time, the glue can be intermittently dropped from the middle groove of the hollow rod 5 to the surface of the glue coating roller 11 below during the rotation of the hollow rod 5, so that the glue coating roller 11 can coat the wood board of different thicknesses during rotation, thereby improving the application range. In addition, the glue coating bin 2 can support and fix the hollow rod 5 and the glue storage bin 15, and prevent the glue stored in the glue storage bin 15 from falling directly by the contact between the hollow rod 5 and the glue storage bin 15, and the conveyor belt 16 can continuously drive the wood board to pass through the glue coating roller 11, and the surface of the conveyor belt 16 can be provided with friction pads or the like according to the needs to ensure the friction between the conveyor belt 16 and the wood board, and the driving wheel 6 and the driven wheel 8 can be limited by the U-shaped plate one 3, the glue coating bin 2, and the U-shaped plate two 12 and the connecting frame 10, respectively, to prevent horizontal shaking during movement, and the movement direction of the limiting frame 14 can be guided by the glue coating bin 2 to ensure that the limiting frame 14 does not move vertically when acted on by the rotating plate 13, and the rotating rod 18 can prevent excessive friction between the belt 7 and the limiting frame 14 when the belt 7 is acted on by the limiting frame 14, and the protrusion 17 can limit the position of the connecting frame 10 to prevent the connecting frame 10 from moving downward too much and causing the glue coating roller 11 in the connecting frame 10 to contact the conveyor belt 16.

[0029] Referring to Figure 5 The trapezoidal block one 19 is slidably connected to the front and rear sides of the glue coating bin 2, the trapezoidal block two 20 is abutted to the bottom of the trapezoidal block one 19, the guide plate 21 is fixedly connected to the side close to the trapezoidal block two 20, the bottom end of the trapezoidal block two 20 is slidably connected to the top end of the base 1, the connecting plate 22 is fixedly connected to the top end of the base 1, the plurality of rolling balls 23 are rotatably connected to the top end of the connecting plate 22, the U-shaped plate three 24 is arranged on the front and rear sides of the base 1, and the bottom end of the U-shaped plate three 24 is fixedly connected to the top end of the trapezoidal block one 19.

[0030] Specifically, the slope between the trapezoidal block one 19 and the trapezoidal block two 20 and the self-weight of the trapezoidal block one 19 can make the trapezoidal block two 20 force the guide plate 21 with a certain arc to move close to each other along the base 1, and then limit the movement direction of the wood board from both sides after contacting with the wood board, prevent the wood board from being skewed and affecting normal gluing, and support the area of the wood board not in contact with the conveyor belt 16 through the connecting plate 22 and the uniformly distributed balls 23, and the U-shaped plate three 24 can cooperate with the gluing bin 2 to ensure that the trapezoidal block one 19 on both sides moves synchronously, thereby making the wood board on both sides receive the same thrust.

[0031] Working principle: In actual use, the output end of the servo motor 4 can pass through the gluing bin 2 and drive the driving wheel 6 and the hollow rod 5 to rotate through the hole reserved in the U-shaped plate one 3, wherein when the hollow rod 5 rotates, the glue can be intermittently dropped from the glue storage bin 15 to the surface of the glue roller 11 below through the middle channel of the hollow rod 5 to prevent the glue from being wasted when it is continuously released, and the driving wheel 6 can drive the driven wheel 8 to rotate through the belt 7 on the surface of the driving wheel 6, thereby making the glue roller 11 stably obtain the power output by the servo motor 4 through the connection between the driven wheel 8 and the glue roller 11 under the support of the connecting frame 10, and as the wood board gradually approaches the glue roller 11 under the drive of the conveyor belt 16, the glue roller 11 in rotation can be pushed up to the upper surface of the glue roller 11 by the wood board, and the connecting frame 10 connected with the glue roller 11 can drive the U-shaped plate two 12 and the driven wheel 8 to move up, at this time, the rotation of the limiting frame 14 and the inner rotating rod 18 can make the belt 7 concave inward through the rotation of the rotating plate 13, so as to compensate for the looseness of the belt 7 when the driven wheel 8 moves up, prevent the rotation of the driven wheel 8 and the glue roller 11 from being affected, and the wrap angle formed by the belt 7 when it is concave inward can be further increased to make the transmission more stable and reliable, and the glue roller 11 can continue to rotate under the drive of the adjusted belt 7 and the driven wheel 8, so as to evenly apply the glue on the surface of the wood board moving with the conveyor belt 16, thereby achieving the purpose of being suitable for different thicknesses and different layers of plywood production requirements, and in cooperation with the U-shaped plate three 24, the trapezoidal block one 19 on both sides can move the guide plate 21 by the same distance through the trapezoidal block two 20, so as to limit the movement direction of the wood board from both sides, prevent the wood board from being skewed and affecting normal gluing.
