[0025] The glue - coating mechanism 2 includes a first frame 201. The bottom of the first frame 201 is fixedly connected to the conveyor 1. Both sides of the top of the first frame 201 are fixedly connected with cylinders 202. The bottom of the output end of the cylinder 202 penetrates through the inner cavity of the first frame 201 and is fixedly connected with a connecting block 203. A storage box 204 is fixedly connected between the two connecting blocks 203. A discharge hole 205 is opened at the bottom of the storage box 204. A discharge pipe 206 which is used in cooperation with the discharge hole 205 is fixedly connected to the bottom of the storage box 204. A lifting plate 207 is arranged at the top of the storage box 204.

The bottom of the sealing block 208 penetrates through the storage box 204 and extends into the inner cavity of the discharge hole 205. Mounting frames 209 are arranged at the bottom of the front side and the rear side of the storage box 204. A pressure roller 210 is movably connected between the two sides of the inner cavity of the mounting frame 209. Lifting rods 211 are fixedly connected to both sides of the top of the mounting frame 209. A tension spring 212 and a mounting plate 213 are sequentially sleeved on the surface of the lifting rod 211 from top to bottom. The surface of the mounting plate 213 is fixedly connected to the storage box 204. The top of the lifting rod 211 is fixedly connected with a connecting plate 214. The surface of the connecting plate 214 is fixedly connected to the lifting plate 207. The top and the bottom of the tension spring 212 are respectively fixedly connected to the connecting plate 214 and the mounting plate 213. By setting the glue - coating mechanism 2, when the pressure roller 210 presses the board, the closure of the discharge hole 205 can be automatically released. At this time, the glue will be discharged through the discharge hole 205 and the discharge pipe 206 to automatically coat the board. By setting the scraping glue assembly 3, not only can the excess glue on the surface of the board be scraped off, but also it can be adjusted according to the thickness of the glue, which is convenient for use.

[0026] Referring to Figure 1 and Figure 5, the glue scraping assembly 3 includes a second frame 301. A handwheel 302 is provided at the top of the second frame 301. A screw rod 303 is fixedly connected to the bottom of the handwheel 302. The bottom of the screw rod 303 penetrates through the inner cavity of the second frame 301 and is movably connected to an adjusting plate 304. A scraping plate 305 is fixedly connected to the bottom of the adjusting plate 304. By cooperating with the handwheel 302, the screw rod 303 can be rotated. When the screw rod 303 rotates, it can drive the adjusting plate 304 to adjust its height. The adjusting plate 304 cooperates to drive the scraping plate 305 to move downward for adjustment. When the plate body is conveyed on the conveyor 1, the scraping plate 305 can automatically scrape off the excess glue on the surface of the plate body.

[0027] Refer to Figure 1 and Figure 5 , the bottom of the screw rod 303 is movably connected to the adjusting plate 304 through a bearing. A threaded hole for cooperating with the screw rod 303 is provided at the top of the second frame 301. By providing the bearing, it is convenient for the connection between the screw rod 303 and the adjusting plate 304. By providing the threaded hole, it is convenient for the cooperation between the screw rod 303 and the second frame 301.

[0028] Refer to Figure 1 and Figure 5 , both sides of the adjusting plate 304 are fixedly connected with sliding blocks 306. A sliding shell 307 is sleeved on the surface of the sliding blocks 306. The surface of the sliding shell 307 is fixedly connected with the inner wall of the second frame 301. By providing the sliding shell 307, the moving range of the sliding blocks 306 can be restricted. By providing the sliding blocks 306 and the sliding shell 307, the stability of the movement of the adjusting plate 304 can be improved.

[0029] Refer to Figure 1 and Figure 2 , limit rods 215 are fixedly connected to the four corners of the top of the material storage box 204. The tops of the limit rods 215 penetrate through the top of the first frame 201 and are fixedly connected with stoppers 216. By providing the limit rods 215, the stability of the adjustment of the material storage box 204 can be improved. By providing the stoppers 216, the adjustment range of the material storage box 204 can be restricted.

[0030] Refer to Figure 2 and Figure 3 , both sides of the pressure roller 210 are movably connected to the inner wall of the mounting frame 209 through a rotating shaft. A limiting hole for cooperating with the lifting rod 211 is provided at the top of the mounting plate 213. By providing the rotating shaft, it is convenient for the installation and use of the pressure roller 210. By providing the limiting hole, it is convenient for the installation and use of the lifting rod 211.

[0031] Refer to Figure 4 , the surface of the sealing block 208 is in contact with the inner wall of the discharge hole 205. The bottom of the sealing block 208 is made of rubber. By providing the sealing block 208, it can be used to close the discharge hole 205. By providing rubber, the sealing performance can be guaranteed.

[0032] Working principle: Place the plate to be coated on the conveyor 1 for transportation. Subsequently, control the operation of the cylinder 202 to drive the connecting block 203 to move downward. The connecting block 203 drives the storage box 204 to move downward. At this time, the pressure roller 210 will also gradually approach the plate until it is tightly attached. When the storage box 204 continues to move downward, the height of the pressure roller 210 remains unchanged. The heights of the lifting rod 211, connecting plate 214, lifting plate 207, and sealing block 208 connected to the pressure roller 210 also remain unchanged. When the storage box 204 moves downward, the sealing of the discharge hole 205 by the sealing block 208 is gradually released. The colloid in the storage box 204 is discharged through the discharge hole 205 and the discharge pipe 206, and the plate can be coated. After the coating is completed, the cylinder 202 drives the storage box 204 to move upward. At this time, due to the setting of the tension spring 212, it will drive the connecting plate 214 to move downward. The connecting plate 214 drives the sealing block 208 to move downward to the lower part of the inner cavity of the storage box 204 through the cooperation of the lifting plate 207 until the sealing block 208 closes the discharge hole 205. At this time, the discharge of the colloid can be avoided. Automatic gluing can be achieved while the pressure roller 210 presses the plate tightly, and it can be automatically closed when gluing is not required. By cooperating with the handwheel 302, the screw 303 can be rotated. When the screw 303 rotates, it can drive the adjusting plate 304 to adjust the height. The adjusting plate 304 cooperates to drive the scraping plate 305 to move downward for adjustment. When the plate is transported on the conveyor 1, the scraping plate 305 can automatically scrape off the excess colloid on the surface of the plate, which is convenient for use.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
