[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-7An automatic embossing device for printing labels on wooden boxes includes a conveying structure 2, which includes a frame 201. Guard plates 202 are installed on both sides of the frame 201. A conveying component is provided between the frame 201 and the two guard plates 202, and several carrier plates 206 are provided on the conveying component. Limiting frames 207 are bolted to the carrier plates 206. Several support frames 1 are installed on the back of one of the guard plates 202, and an embossing structure 3 is provided between the tops of the support frames 1. An embossing structure 3 is bolted to both guard plates 202. The mounting brackets 208 corresponding to the printing structure 3 are equipped with fixing cylinders 209. The wooden box is transported by the support frame 1, supported by the carrier plate 206, and limited by the limiting frame 207. During the printing process, the fixing cylinders 209 can clamp and fix the wooden box to improve the stability of the wooden box during the printing process. The printing operation of the wooden box by the printing structure 3 reduces manual intervention, reduces the labor intensity of the operators, and improves efficiency.

[0020] Furthermore, the conveying component includes two rotating shafts 203 rotatably connected between the two guard plates 202 via bearings and bearing seats. Two sprockets 204 are fixedly connected to the outer surfaces of the two rotating shafts 203. Two conveying chains 205 are rotatably connected between the four sprockets 204. The carrier plate 206 is connected between the two conveying chains 205, and the carrier plate 206 can be driven and conveyed through the conveying chains 205.

[0021] Furthermore, a protective box 210 is installed on the side of one of the protective plates 202. A drive motor is installed inside the protective box 210. A transmission component is installed between the drive motor and one end of one of the rotating shafts 203. The transmission component uses a synchronous belt and a synchronous pulley. The drive motor can drive the corresponding rotating shaft 203 to rotate through the synchronous belt and the synchronous pulley, and then drive the carrier plate 206 to move with the cooperation of the sprocket 204 and the conveyor chain 205.

[0022] Furthermore, notches are provided at both ends of the guard plate 202 to avoid the carrier plate 206, so that when the carrier plate 206 reaches the end of the guard plate 202 and rotates downward under the drive of the conveyor chain 205, it will not interfere with the guard plate 202.

[0023] Furthermore, the embossing structure 3 includes a support frame 301 mounted on the support frame 1. A driving component is provided on the support frame 301, and the driving component is connected to a connecting frame 311. Two second cylinders 312 are mounted on the connecting frame 311. The piston rods of the two second cylinders 312 are connected to a fourth connecting plate 313. Two fifth connecting plates 315 are provided below the connecting frame 311. A connecting shaft 314 is connected between the fifth connecting plate 315 and the fourth connecting plate 313, and the outer surface of the connecting shaft 314 passes through the connecting frame 311. The second cylinders 312 are used to drive the fifth connecting plate 315 to rise and fall through the fourth connecting plate 313 and the connecting shaft 314.

[0024] Furthermore, the bottom of each of the two fifth connecting plates 315 is connected to a crossbeam 316. The bottom of each of the two crossbeams 316 is respectively provided with an ink return blade 318 and an ink scraper blade 319. Each ink return blade 318 and ink scraper blade 319 is provided with several fixing clips 317. The fixing clips 317 are set on the crossbeams 316, and the fixing clips 317 are provided with handle bolts. During the lifting and lowering process of the fifth connecting plate 315, the ink return blade 318 and the ink scraper blade 319 can be lifted and lowered.

[0025] Furthermore, the driving component includes a first lifting frame 321 disposed within the support frame 301, a third cylinder 323 mounted on the first lifting frame 321, a second lifting frame 322 connected to the piston rod of the third cylinder 323, an elongated opening 302 opened on the support frame 301, and the end of the second lifting frame 322 passing through the elongated opening 302 and extending to the outside of the support frame 301 and connected to a linear module 304.

[0026] Furthermore, the moving end of the linear module 304 is connected to a third connecting plate 310. A first cylinder 309 is mounted on the top of the third connecting plate 310. The piston rod of the first cylinder 309 is connected to a second connecting plate 308. A cross guide rail is provided between the second connecting plate 308 and the third connecting plate 310. A connecting frame 311 is mounted on the second connecting plate 308. The first cylinder 309 can drive the second connecting plate 308 to rise and fall.

[0027] Furthermore, two limiting rods 320 are fixedly installed inside the support frame 301. The outer surfaces of the two limiting rods 320 pass through the second lifting frame 322 and the first lifting frame 321. A threaded rod is rotatably connected inside the support frame 301 via a bearing. The outer surface of the threaded rod is threadedly connected to the first lifting frame 321. The second lifting frame 322 has a hole to avoid the threaded rod. The top of the threaded rod extends above the support frame 301 and is connected to a handwheel 303. When the handwheel 303 is turned, the threaded rod can be driven to rotate. During the rotation of the threaded rod, the first lifting frame 321 can be raised and lowered.

[0028] Furthermore, two support arms 305 are installed on the non-moving end of the linear module 304. A C-shaped frame 324 is provided below each of the two support arms 305. A first connecting plate 306 is connected between the C-shaped frame 324 and the support arm 305. A screen 307 is inserted between the two C-shaped frames 324, and bolts for fixing the screen 307 are provided on the C-shaped frame 324.

[0029] Robotic arms for picking up and placing wooden crates can be installed at both ends of the guard plate 202. The robotic arms place the wooden crates on top of the carrier plate 206 and limit them by the limiting frame 207. The drive motor drives the carrier plate 206 to move through the transmission components, rotating shaft 203, sprocket 204 and conveyor chain 205, so that the carrier plate 206 moves with the wooden crates to below the screen 307. Then, the wooden crates are clamped by two fixed cylinders 209. The third cylinder 323 drives the second lifting frame 322 to descend, so that the screen 307 presses down on the top of the wooden crates. The first cylinder 309 pushes the second connecting plate 308 to descend. The ink return blade 318 remains raised, while the ink scraper blade 319 descends. The linear module 304 drives the third connecting plate 308 to descend. 10. The linear movement causes the doctor blade 319 to move linearly, scraping the ink on the screen 307 to print the logo onto the wooden box via screen printing. Then, the doctor blade 319 rises, the return blade 318 descends, and the linear module 304 drives the third connecting plate 310 to move back, pushing the ink on the screen 307 back through the return blade 318. The first cylinder 309 drives the second connecting plate 308 and the connecting frame 311 to rise, and the third cylinder 323 drives the second lifting frame 322 to rise, causing the screen 307 to separate from the wooden box. The fixing cylinder 209 releases the fixing of the wooden box, and the wooden box continues to be transported to the end by the conveying structure 2, and then picked up by the robot.
