Specifically, a first connecting part is constructed on the lifting plate 4, the driven roller 15 is rotationally connected to the first connecting part, a second connecting part is constructed on the supporting plate 8, the driving roller 16 is rotationally connected to the second connecting part, the driving wheel 17 is positioned between the driving roller 16 and the driven roller 15, friction wheels in the prior art can be selected among the driving roller 16, the driven roller 15 and the driving wheel 17, friction transmission can be realized among the driving roller 16, the driven roller 15 and the driving wheel 17, a power source is arranged on the supporting plate 8 to drive the driving roller 16 to rotate, and when the driving roller 16 rotates, the driving wheel 17 and the driven roller 15 can drive a second synchronous wheel 5 to rotate, so that the second synchronous belt 6 is driven to carry out speed reduction transmission on a rotary cutting veneer. The rotary cutting veneer stacking device has the advantages that when the power source drives the second synchronous belt 6 to convey the rotary cutting veneer through the structures such as the driving roller 16, the speed of the power source driving the second synchronous belt 6 to convey the rotary cutting veneer is adjustable, namely the speed of the second synchronous belt 6 to convey the rotary cutting veneer can be adjusted, so that after the rotary cutting veneer is switched to the bottom of the second synchronous belt 6, the speed of the second synchronous belt 6 is gradually reduced, the rotary cutting veneer is further forced to perform deceleration movement, the horizontal speed of the rotary cutting veneer is reduced to zero after the rotary cutting veneer moves to a specific position, and therefore the influence of the horizontal speed of the rotary cutting veneer on the rotary cutting veneer when the rotary cutting veneer falls into a stacking area can be eliminated, and the rotary cutting veneer can be stacked as orderly as possible.
As an alternative to the above-described adjustment of the conveying rate of the second timing belt 6 by the power source, it is preferable that the driving roller 16 and the driven roller 15 are each configured in a truncated cone shape, the support plate 8 is slidably connected with a slider 18, and the driving wheel 17 is rotatably connected with the slider 18. Specifically, the driving roller 16 and the driven roller 15 are both configured in a truncated cone shape (i.e. one end diameter is larger than the other end diameter), the central axes of the driving roller 16 and the driven roller 15 are parallel to each other and are opposite to each other (as shown in fig. 6), when the belt wheel conveying mechanism is between the first stroke and the second stroke (i.e. when the connecting post 12 is relatively abutted against the first horizontal plane 113), opposite sides of the driving wheel 17 are respectively in transmission connection with the driving roller 16 and the driven roller 15, otherwise, when the connecting post 12 is relatively moved away from the position of the first horizontal plane 113, the driving roller 16 and the driven roller 15 lose transmission; the first connecting part of the supporting plate 8 is provided with a through groove 19, the through groove 19 is arranged along the side line of the opposite side of the driving roller 16 and the driven roller 15, the sliding block 18 is connected in the through groove 19 in a sliding way, when the connecting column 12 is relatively abutted against the first horizontal plane 113, even if the sliding block 18 moves along the through groove 19, the driving roller 16 and the driven roller 15 can be in transmission connection through the transmission wheel 17, the function of the arrangement is that when the sliding block 18 is positioned on the right side of the through groove 19, one end with a larger diameter of the driving roller 16 is in transmission connection with one end with a smaller diameter of the driven roller 15 (through transmission wheel 17), otherwise, when the sliding block 18 moves leftwards along the through groove 19, one end with a smaller diameter of the driving roller 16 is in transmission connection with one end with a larger diameter of the driven roller 15, namely, the sliding block 18 moves leftwards along the through groove 19 under the condition of not changing the rotation speed of the driving roller 16, so that the speed of the rotary cutting veneer can be reduced.
If the speed difference between the rotary cut single board conveyed by the first synchronous belt 2 and the second synchronous belt 6 is larger, the rotary cut single board is easily pulled by the first synchronous belt 2 and the second synchronous belt 6 when the rotary cut single board is switched from the first synchronous belt 2 to the second synchronous belt 6, and the rotary cut single board is offset, and the like, therefore, the driving roller 16, the driving wheel 17 and the like are arranged, when the rotary cut single board is switched from the first synchronous belt 2 to the second synchronous belt 6, the speed of the rotary cut single board conveyed by the second synchronous belt 6 is basically the same as the speed of the rotary cut single board conveyed by the first synchronous belt 2, so that the rotary cut single board can be smoothly switched and abutted under the second synchronous belt 6, when the belt pulley reducing mechanism is positioned between the first stroke and the second stroke, the driving sliding block 18 is far away from the second synchronous belt 6 along the through groove 19, so as to gradually reduce the speed of the second synchronous belt 6, and smoothly reduce the conveying speed of the rotary cut single board until the speed of the belt pulley reducing mechanism runs the second stroke, and the speed of the rotary cut single board at the bottom of the second synchronous belt 6 is nearly zero, so that the offset of the rotary cut single board falling into the horizontal stacking area can be avoided as much as possible.
Further, a linkage mechanism is also included for driving the slider 18 and the slide plate 11 to slide synchronously along the support plate 8. Specifically, in the above embodiment, the driving force of the slider 18 moving along the through slot 19 may be selected from the structures of a cylinder in the prior art, etc., so as to operate synchronously by matching the cylinder with the linear driving mechanism, thereby driving the slider 18 and the slide 11 to slide synchronously along the support plate 8. Preferably, in the present embodiment, the slide 11 is configured with an extension 20, the extension 20 is configured with a movable slot, and the slider 18 is fixed with a synchronizing rod 21, and the synchronizing rod 21 is located in both the through slot 19 and the movable slot. The advantage of this arrangement is that when the slide 11 is far away from the second synchronous belt 6 along the support plate 8, the synchronous rod 21 can be forced to move synchronously through the inner wall of the movable groove, and the sliding groove 13 and the through groove 19 are different in arrangement direction, so that the moving track of the slide 11 and the sliding block 18 is different, the movable groove is set to be long, when the synchronous rod 21 and the sliding block 18 are forced to move through the inner wall of the movable groove, the synchronous rod 21 can move in the movable groove in a manner of adapting to different movement tracks of the slide 11 and the sliding block 18, and therefore, the linear driving mechanism can drive the slide 11 to move and simultaneously drive the sliding block 18 to move along the through groove 19. The belt pulley speed reducing mechanism has the advantages that when the linear driving mechanism drives the sliding plate 11 to move away from the second synchronous belt 6 along the sliding groove 13, the belt pulley speed reducing mechanism can be forced to move a first stroke and a second stroke successively through the sliding plate 11, the connecting column 12 is relatively abutted against the first horizontal plane 113 between the first stroke and the second stroke, when the sliding plate 11 and the sliding block 18 synchronously move on the supporting plate 8, the sliding block 18 is synchronously moved away from the second synchronous wheel 5 when the sliding plate 11 moves away from the second synchronous wheel 5, namely, the connecting column 12 relatively moves on the first horizontal plane 113, the driving wheel 17 moves between the driving roller 16 and the driven roller 15 to reduce the rotating speed of the second synchronous wheel 5, so that the speed of the second synchronous conveying rotary-cut single plate is gradually reduced, and when the linear driving mechanism drives the sliding plate 11 to reset, the belt pulley speed reducing mechanism is directly reset under the action of the elastic piece 7, and the driven roller 15 moves along with the lifting plate 4 and is separated from the driving wheel 17, so that the second synchronous wheel 5 is not driven, namely, after the rotary-cut single plates are stacked, the belt pulley speed reducing mechanism is not driven by the driving roller 16, and the waste of kinetic energy is avoided as much as possible.
