[0035] In this embodiment, as shown in the figure, Figure 3 The feeding and discharging mechanism 4 comprises a motor frame 412, a driving motor 413, a first transmission belt 414 and a second transmission belt 415. The motor frame 412 is fixedly installed at the top of one of the bottom plates 401 located at the left end of the veneer laying machine 1.

[0037] In other aspects, the embodiment also provides a pushing mechanism 5 for feeding the melamine boards to be veneered stacked on the feeding plate 402 into the veneer laying machine 1, and pushing the melamine boards with completed veneer to the top end of the discharging plate 403 for stacking, as shown in the figure, Figures 4 to 6 The pushing mechanism 5 comprises a pushing frame 501. The middle of the pushing frame 501 is arranged at the top end of the veneer laying machine 1. The left end of the pushing frame 501 is located at the left side of the conveying assembly 2. The right end of the pushing frame 501 is located between the veneer laying machine 1 and the discharging plate 403.

[0038] In this embodiment, as shown in the figure, Figures 1 to 6As shown, the pushing mechanism 5 comprises two pushing plates 502, two guide plates 503 and two guide blocks 504. The two pushing plates 502 are fixedly installed at the left and right bottom ends of the pushing frame 501 respectively. The two guide plates 503 are fixedly installed at the front and rear sides of the top end of the veneer facing machine 1 respectively. Two guide slots are formed in the side wall of each guide plate 503. The guide block 504 is arranged in each guide slot and divides the guide slot into a straight slot and an inclined slot.

[0039] The pushing plate 502 is moved by the pushing frame 501. The feeding and discharging of the board are realized by the pushing plate 502. The guide plate 503 and the guide block 504 guide the connecting shaft 507.

[0040] In this embodiment, as shown in Figure 5 and Figure 6 , the pushing mechanism 5 comprises a connecting frame 505, a partition plate 506 and a connecting shaft 507. The connecting frame 505 is located at the side of the guide plate 503 away from the middle of the top end of the veneer facing machine 1. The top end of the connecting frame 505 is fixedly connected with the guide block 504. The bottom end of the connecting frame 505 is fixedly installed at the top end of the veneer facing machine 1. The top end of the partition plate 506 is movably connected with the end of the guide block 504 close to the discharging plate 403. The connecting shaft 507 comprises two connecting shafts. The two ends of the connecting shaft 507 are movably installed in the guide slots of the two guide plates 503 respectively. The top end of the connecting shaft 507 is movably connected with the top end of the pushing frame 501.

[0041] In this embodiment, as shown in Figure 4 and Figure 5 , the pushing mechanism 5 comprises a pushing frame 508, a lifting groove 509 and an electric push rod 510. The pushing frame 508 comprises two pushing frames. The two pushing frames 508 are arranged at the side of the two connecting shafts 507 close to the supporting frame 3. The lifting groove 509 comprises two groups of lifting grooves. The two groups of lifting grooves 509 are fixedly installed at the two ends of the two pushing frames 508 respectively. The two groups of lifting grooves 509 are movably sleeved on the two connecting shafts 507 respectively. One end of the electric push rod 510 is fixedly installed at the top end of the supporting frame 3. The output shaft of the electric push rod 510 is fixedly installed at the middle of the pushing frame 508 close to the supporting frame 3.

[0042] The pushing frame 508 is moved by the electric push rod 510 to the direction away from the supporting frame 3. The lifting groove 509 is moved by the pushing frame 508. The connecting shaft 507 is moved by the lifting groove 509. The pushing frame 501 moves synchronously with the two connecting shafts 507. The two ends of the connecting shaft 507 move in the guide slots of the guide plates 503. First, the two ends of the connecting shaft 507 move along the straight slots. When the two ends of the connecting shaft 507 contact the partition plate 506, the partition plate 506 is lifted. After the two ends of the connecting shaft 507 leave the partition plate 506, the partition plate 506 falls. When the two ends of the connecting shaft 507 move from the end of the straight slot close to the supporting frame 3 to the end close to the discharging plate 403, the pushing frame 501 moves a distance of one board along with the connecting shaft 507.

[0043] The connection shaft 507 is moved along the partition plate 506 to the inclined groove, and the connection shaft 507 gradually rises in the lifting groove 509 during the movement, and when rising to the top end of the inclined groove, the connection shaft 507 also rises to the top end of the lifting groove 509, and the connection shaft 507 at the top end of the inclined groove falls into the straight groove close to the support frame 3, so that the connection shaft 507 is reset, and the pushing frame 501 is reset along the connection shaft 507.

[0044] Working principle: when the present application is used, the stacked melamine board to be pasted is placed on the feeding plate 402 by a forklift or the like, at this time, the feeding plate 402 is at the lowest end, and the discharging plate 403 is at the highest end without a board, and after the melamine board to be pasted is placed, the electric push rod 510 is started to drive the pushing frame 508 to move away from the support frame 3, the lifting groove 509 is driven to move, and the connection shaft 507 is driven to move, so that the pushing frame 501 moves synchronously along the two connection shafts 507, and the two ends of the connection shaft 507 move in the guide groove on the guide plate 503, first moving along the straight groove, and lifting the partition plate 506 when contacting the partition plate 506, and after the connection shaft 507 moves away from the partition plate 506, the partition plate 506 falls, and when the connection shaft 507 moves from the end of the straight groove close to the support frame 3 to the end close to the discharging plate 403, the pushing frame 501 moves a distance of a board along the connection shaft 507;

[0045] The melamine board to be pasted on the feeding plate 402 is pushed to the conveying assembly 2 by the pushing plate 502 at the left bottom end of the pushing frame 501, and the board is conveyed to the inside of the veneer machine 1 for veneering, and the pushing plate 502 at the right bottom end of the pushing frame 501 pushes the melamine board that has been veneered to the top end of the discharging plate 403;

[0046] After that, the pushing frame 508 is retracted by the electric push rod 510, and the connection shaft 507 is retracted by the lifting groove 509, and when the connection shaft 507 moves close to the support frame 3, the two ends of the connection shaft 507 move in the guide groove, and due to the action of the partition plate 506, the connection shaft 507 moves along the partition plate 506 to the inclined groove, at this time, the connection shaft 507 gradually rises in the lifting groove 509 during the movement, and when rising to the top end of the inclined groove, the connection shaft 507 also rises to the top end of the lifting groove 509, and the connection shaft 507 at the top end of the inclined groove falls into the straight groove close to the support frame 3, so that the connection shaft 507 is reset, and the pushing frame 501 is reset along the connection shaft 507;

[0047] In the process of the pusher frame 501 rising, the pusher plate 502 is driven to rise, so that the pusher plate 502 does not block the finished melamine board conveyed by the conveying assembly 2, and when the melamine board is conveyed to the designated position, the conveying assembly 2 stops, and after the pusher plate 502 resets, the pusher frame 501 pushes the pusher frame 508 again to drive the right pusher plate 502 to push the finished melamine board to the unloading plate 403 for stacking;

[0048] During the process of the pusher frame 501 rising to reset, the feeding plate 402 is driven to rise and the unloading plate 403 is simultaneously lowered to realize automatic feeding and unloading. In this process, the driving motor 413 is started, then the first transmission belt 414 drives the threaded rod 411 to rotate, and the second transmission belt 415 simultaneously drives the two threaded rods 411 to rotate. When the threaded rod 411 under the feeding plate 402 rotates, the push plate 409 is driven to move towards the second transmission belt 415, and the bottom end of the second support rod 405 is driven by the push plate 409 to move towards the second transmission belt 415. At this time, the top end of the first support rod 404 is also simultaneously driven by the second support rod 405 to move towards the second transmission belt 415, so that the feeding plate 402 rises. Since the threads on the two threaded rods 411 are in opposite directions, the threaded rod 411 under the unloading plate 403 drives the push plate 409 to move away from the second transmission belt 415, so that the unloading plate 403 descends. Therefore, the rising distance of the feeding plate 402 is the same as the descending distance of the unloading plate 403. The feeding plate 402 is controlled to rise by one thickness of the board each time, and the pusher plate 502 is used to push the material, so that the functions of automatically feeding the stacked melamine board and automatically unloading and stacking the finished board are realized.
