[0027] As shown, Figure 4 The conveying assembly includes mounting plates 161, conveying belts 17, conveying rollers 171 and second motors 18. Each mounting plate 161 is connected to the top end of each centering plate 16 by welding. Each two conveying rollers 171 are distributed in front of and behind each mounting plate 161 and are rotatably connected to the mounting plate 161. Each conveying belt 17 is rotatably connected between two longitudinally aligned conveying rollers 171, with the bottom end approaching the top end of the conveyor belt 2. Each second motor 18 is connected to the top end of each mounting plate 161 by bolts, with the output shaft facing downward. The top end of the front conveying roller 171 is fixedly connected with the output shaft of the corresponding second motor 18. When the board is conveyed forward by the conveyor belt 2, it will contact the conveying belt 17 and be continuously conveyed due to the movement of the conveying belt 17, slowing down the sliding speed of the board under the action of gravity, so that the board can be uniformly transferred to the buffer plate 5.

[0028] When the device is needed, first, the support frame 1 is placed between two production lines, ensuring that the discharge end of the previous production line is aligned with the placement plate 8, and the feeding end of the next production line is aligned with the buffer plate 5, then the two electric push rods 19 are started, the extension end is shortened, and the two movable plates 23 are moved inward, the two center plates 16 drive the two conveyor belts 17 to move inward with the two movable plates 23, so as to flexibly adjust the distance between the two center plates 16 according to the actual transverse length of the plate, then the first motor 3 and the two second motors 18 are started, the output shaft of the first motor 3 drives the front side conveying roller 201 to rotate counterclockwise, cooperates with the rear side conveying roller 201, and drives the conveying belt 2 to rotate counterclockwise, the output shaft of the two second motors 18 drives the front side two conveying rollers 171 to rotate counterclockwise, cooperates with the rear side two conveying rollers 171, and drives the two conveyor belts 17 to rotate counterclockwise;

[0029] When the previous production line sends the processed plate to the placement plate 8, the placement plate 8 rotates counterclockwise due to the weight of the plate, the torsion spring 11 is deformed, in the process of rotation, the baffle 13 temporarily blocks the plate on the placement plate 8, preventing it from falling too early, at the same time, the second guide rod 14 rotates counterclockwise with the placement plate 8, and contacts and is stopped by the top block 12 when it rotates to a certain angle, with the continuous rotation of the placement plate 8, the second guide rod 14 remains in the state of being stopped by the top block 12, so that the baffle 13 is stationary, and the second spring 15 is compressed, when the placement plate 8 rotates counterclockwise to the appropriate angle and is stopped by the rear end of the conveying belt 2, it is away from the baffle 13, at this time, the plate smoothly slides through the gap between the placement plate 8 and the baffle 13 to the rear end of the conveying belt 2, with the continuous rotation of the conveying belt 2, the plate is driven to gradually separate from the placement plate 8, the torsion spring 11 returns to its original shape, promoting the placement plate 8 to rotate clockwise to return to the initial position, at the same time, the second guide rod 14 is separated from the top block 12, and the second spring 15 returns to its original state;

[0030] After the plate separates from the placement plate 8, it is conveyed forward under the action of its own gravity and the traction of the conveying belt 2, in the process of conveying, the plate contacts the two center plates 16 for positioning and adjustment, ensuring that it remains in the center state on the conveying belt 2, avoiding the deviation of the plate in the conveying process, the plate continues to move forward and contacts the two conveyor belts 17, the two conveyor belts 17 rotate at the same speed as the conveying belt 2, assisting the conveying belt 2 to stably convey the plate, slowing down the sliding speed of the plate under the action of gravity, and ensuring that the plate can move forward in a stable and uniform manner;

[0031] When the front end of the board detaches from the conveyor belt 2, it contacts the sponge roller 4 for cushioning, and then transfers to the buffer plate 5. The buffer plate 5 moves downward due to the weight of the board, and the first spring 7 is compressed accordingly, thus playing a cushioning role, reducing direct collision between the board and the buffer plate 5, and protecting the corners of the board from wear. When the board is completely transferred to the buffer plate 5, its front end extends beyond the edge of the buffer plate 5 and enters the feeding end of the next production line. At this time, the relevant equipment of the next production line quickly takes over the board and performs subsequent processing. Thus, the unloading process of a board is completed.

[0032] It is important to note that in order to ensure that the rotation speeds of the two conveyor belts 17 and the conveyor belt 2 are consistent, the rotation speeds of the output shafts of the first motor 3 and the two second motors 18 should be precisely controlled. The rotation speeds can be adjusted according to the length ratio of the conveyor belts 17 and 2 to ensure that the material transported by the conveyor belts 17 and 2 is equal in the same amount of time, thereby maintaining the coordination and efficiency of the entire transmission system.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
