DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present utility model in conjunction with embodiments.

[0021] Please refer to Figures 1-4, the utility model provides a plywood stacking device, which includes a placement board 1. Four corners of the top end of the placement board 1 are fixedly provided with brackets 2. The inner wall of the bracket 2 is provided with a limit activity groove 3. The center of the inner wall of the limit activity groove 3 is fixedly provided with a limit rod 4. The outer wall of the limit rod 4 is sleeved with a tension spring 5. The top end of the tension spring 5 is fixedly provided with a movable block 6. The top end of the movable block 6 is fixedly provided with a movable column 7. The top ends of the movable columns 7 are jointly fixedly provided with a pressing plate 8. The bottom end of the placement board 1 is provided with a mounting frame 10. The center of the mounting frame 10 is provided with a mounting groove 11. The inner wall of the mounting groove 11 is provided with a servo motor 12. The servo motor 12 is fixedly provided with a rotating rod 13. The other end of the rotating rod 13 is provided with a transmission mechanism 14.

[0022] Through the transmission mechanism 14, it can mainly drive the driving bevel gear 141 to rotate, and then can drive a plurality of driven bevel gears 142 to rotate simultaneously. Thus, it can drive the threaded lead screw 143 to rotate, and further can drive the sliding block 15 to move, so as to drive the clamping plate 16 to move. When the clamping plate 16 moves, the four corners of the plywood can be clamped and positioned.

[0023] Further, as Figure 3 and Figure 4 shown, the transmission mechanism 14 includes a driving bevel gear 141. One end of the driving bevel gear 141 is fixedly arranged on the outer wall of the rotating rod 13. The outer wall of the driving bevel gear 141 is meshed with a plurality of driven bevel gears 142. The centers of the driven bevel gears 142 are fixedly provided with threaded lead screws 143.

[0024] By starting the servo motor 12, it can mainly drive the rotating rod 13 to rotate, thus driving the driving bevel gear 141 to rotate, and then can drive a plurality of driven bevel gears 142 to rotate simultaneously. When the driven bevel gear 142 rotates, it can drive the threaded lead screw 143 to rotate, and further can drive the sliding block 15 to move, so as to drive the clamping plate 16 to move, and further can clamp and position the plywood.

[0025] Further, as Figure 1 、 Figure 3 and Figure 4 shown, the outer walls of the threaded lead screws 143 are all threadedly connected with sliding blocks 15. The top ends of the sliding blocks 15 are fixedly provided with clamping plates 16.

[0026] This solution has the following working process: First, place the plywood on the surface of the placement plate 1, and at the same time start the servo motor 12, which can drive the rotating rod 13 to rotate, thereby driving the driving bevel gear 141 to rotate. When the driving bevel gear 141 rotates, it can drive a plurality of driven bevel gears 142 to rotate. When the driven bevel gears 142 rotate, they can drive the threaded screw rod 143 to rotate. During the rotation of the threaded screw rod 143, it can drive the sliding block 15 to move in a limited way, and further drive the clamping plate 16 to move in a limited way. When the clamping plate 16 moves in a limited way, it can clamp and position the four corners of the plywood, preventing the plywood from not being stacked together when placed, which may cause the center of gravity of the stacked plywood to be unstable and the plywood to easily tilt and collapse. At the same time, when stacking too high, by pulling the pressing plate 8, the movable column 7 can be moved, and further the tension spring 5 can be stretched. During the stretching of the tension spring 5, it can drive the pressing plate 8 to reset, and then fix the top of the plywood, making the stacking effect of the plywood better.

[0027] According to the above working process, it can be seen that: through the action of the tension spring 5, it can drive the pressing plate 8 to reset, so that the bottom end of the pressing plate 8 can be attached to the surface of the plywood, thereby further positioning the plywood.

[0028] Furthermore, as Figure 1 , Figure 2 , Figure 3 shown, a limiting groove 9 is provided on the inner wall of the placement plate 1, and a plurality of sliding blocks 15 are all installed in a limited way on the inner wall of the limiting groove 9.

[0029] Furthermore, as Figure 2 shown, the limiting rod 4 passes through the movable block 6 and the movable column 7.

[0030] Furthermore, as Figure 2 shown, the movable block 6 and the movable column 7 are installed in a limited way on the inner wall of the limiting movable groove 3.

[0031] In summary: By starting the servo motor 12, it can drive the rotating rod 13 to rotate, thereby driving the transmission mechanism 14 to operate, and further driving the sliding block 15 and the clamping plate 16 to move simultaneously, so as to clamp the four corners of the plywood, avoiding the deviation of the plywood when placed, which may cause the unstable center of gravity of the placed plywood.

[0032] The above are only the preferred embodiments of the present utility model, and do not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the present utility model.
