[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] Depend on Figure 1-6 This invention discloses a method for feeding wood into a wood saw, comprising the following steps: The first step is to place the wooden board inside the outer casing 1, and rotate the first clamping mechanism and the second clamping mechanism to the top of the outer casing 1, with the first clamping mechanism and the second clamping mechanism respectively located on both sides of the two ends of the wooden board, so that when the first clamping mechanism and the second clamping mechanism move downward, they can be located on both sides of the wooden board. The second step is that during the rotation of the first clamping mechanism and the second clamping mechanism, the push plate 6 pushes the uppermost wooden board, so that the uppermost wooden board and the second wooden board intersect each other, that is, the uppermost wooden board slides to one side, so that one end of the uppermost wooden board extends to one side. Third, the first lead screw 4 moves downward, causing the first clamping mechanism and the second clamping mechanism to move downward. When it reaches the predetermined position (which could be when the lower end of the second clamping mechanism is fixed on the second wooden board, or it could be done by using a sensor or other means), the first lead screw 4 stops moving downward. Fourth step: The first clamping mechanism and the second clamping mechanism approach each other, and when the first clamping mechanism contacts one end of the wooden board, one end of the wooden board is pressed down. At this time, the other end of the wooden board is raised and clamped by the second clamping mechanism. The lower ends of the first clamping mechanism and the second clamping mechanism are at different heights, with the lower end of the first clamping mechanism being lower. Thus, when the lower end of the second clamping mechanism is against the second layer of wooden board, the lower end of the first clamping mechanism is below the lower end of the first layer of wooden board. When one end of the wooden board is pressed down, this end of the wooden board will not separate from the first clamping mechanism. After the other end of the wooden board is raised, it can be clamped by the second clamping mechanism. As a result, when the first clamping mechanism and the second clamping mechanism move upward, the first layer of wooden board (the uppermost wooden board) can be separated. Fifth step, the first lead screw 4 drives the first clamping mechanism and the second clamping mechanism to move upward, the top layer of wood board is taken out, the first clamping mechanism and the second clamping mechanism rotate to one side of the outer casing 1, and then the wood board is placed on the saw. Step 6: The clamping mechanism moves back above the outer casing 1, and then steps 1 through 5 are repeated.

[0015] When this solution is implemented, the first layer of wooden board can be pushed, which facilitates the first clamping mechanism to clamp one end of the wooden board. Then, one end of the wooden board is pressed down, causing the other end of the wooden board to tilt upward, which facilitates the second clamping mechanism to clamp the other end of the wooden board. Thus, when the first clamping mechanism and the second clamping mechanism rotate, the wooden board can be moved to one side of the outer shell 1, achieving the purpose of automated clamping and picking up of the wooden board.

[0016] The upper end of the outer shell 1 is an open structure. A support rod 2 is fixedly connected to one side of the outer shell 1. A first rotating plate 3 that can rotate is provided on the support rod 2. The first lead screw 4 is provided through the first rotating plate 3. A mounting plate 5 is fixedly connected to the lower end of the first lead screw 4. The first clamping mechanism and the second clamping mechanism are both mounted on the mounting plate 5.

[0017] The first clamping mechanism includes a first sleeve block 8, a second rotating plate 9 is provided at the lower end of the first sleeve block 8, the second rotating plate 9 can rotate at the lower end of the first sleeve block 8, and a second locking block 14 is fixedly connected to one side of the second rotating plate 9 near the lower end. The second clamping mechanism includes a second socket block 15, on which a first locking block 12 is disposed through and connected to the second socket block 15 by a spring 13.

[0018] When the first clamping mechanism and the second clamping mechanism approach each other, the second locking block 14 on the first clamping mechanism can receive the protruding end of the wooden board. When the second clamping mechanism moves, the first locking block 12 on it can push against the side of the wooden board and extend the spring 13. Then, when the wooden board is tilted up, the first locking block 12 can extend under the wooden board. As the first clamping mechanism and the second clamping mechanism move upward, the wooden board is removed.

[0019] The upper ends of the first socket block 8 and the second socket block 15 are both fitted outside the second lead screw 7 and are threaded together. When the second lead screw 7 rotates, the first socket block 8 and the second socket block 15 can move closer to or further away from each other.

[0020] A first rotating shaft 10 is fixedly connected to the second rotating plate 9, and a pressure block 11 is rotatably provided on the first sleeve block 8. A second rotating shaft is fixedly connected to one end of the pressure block 11. Both the first rotating shaft 10 and the second rotating shaft are provided with gear rings so that the pressure block 11 can rotate with the first rotating shaft 10.

[0021] To enable the pusher plate 6 to push the topmost wooden board, and to continue pushing the lower wooden boards after the topmost board is removed, the following technical solution is provided: a third lead screw 18 is provided inside the outer casing 1, a first gear 19 is fixedly connected to the upper end of the third lead screw 18, a third gear 22 is provided on the outer wall of the outer casing 1, and a first actuating tooth 16 is fixedly connected to the first rotating plate 3. The first actuating tooth 16 meshes with the third gear 22, and the third gear 22 meshes with the first gear 19.

[0022] A rotating rod 20 is fixedly connected to the push plate 6, and a second gear 21 is fixedly connected to the end of the rotating rod 20. A fourth gear 28 is installed on the side wall of the outer casing 1. The side and upper end of the fourth gear 28 are provided with tooth surfaces. The second gear 21 meshes with the tooth surface at the upper end of the fourth gear 28. A second actuating tooth 17 is provided on the first rotating plate 3, and the second actuating tooth 17 meshes with the tooth surface on the side of the fourth gear 28.

[0023] The rotating rod 20 is rotatably mounted on the mounting block 23. The mounting block 23 is also provided with a through hole through which the third lead screw 18 passes. Two threaded blocks 24 that can approach each other are provided in the through hole. The two threaded blocks 24 can be tightly attached to the surface of the third lead screw 18, and the threaded blocks 25 are threadedly engaged with the third lead screw 18. Thus, when the first rotating plate 3 rotates, the third lead screw 18 can rotate, thereby driving the mounting block 23 to rotate, which in turn causes the push plate 6 to move downward.

[0024] Connecting rods 25 are fixedly connected to both threaded blocks 24. A rotatable fourth lead screw 26 is also provided inside the mounting block 23. The connecting rods 25 are sleeved on the fourth lead screw 26. A rotating block 27 is also fixedly connected to the fourth lead screw 26. When the push plate 6 moves to the bottom, the user can rotate the rotating block 27 to separate the threaded block 25 from the third lead screw 18, thereby moving the position of the push plate 6.

[0025] The pusher plate 6 moves downwards by a distance equal to the height of a wooden board each time. The lower end of the pusher plate 6 is lower than the lower end of the topmost wooden board.

[0026] The rotation of the first lead screw 4 and the second lead screw 7 can be driven by a motor or by other means. The rotation of the first rotating plate 3 can also be driven by a motor. These driving methods are all existing structures and are not described in detail in this application.
