[0028] The driving unit 200 is disposed on one side of the support platform 101, and includes a motor 201, an eccentric circle 202 disposed on one side of the motor 201, a moving block 203 sleeved on the side wall of the eccentric circle 202, and a waist-shaped rail 204 sleeved on the side wall of the moving block 203; and,

[0029] A cutting machine M is arranged at the bottom of the moving block 203 .

[0030] Furthermore, the support platform 101 is C-shaped, including a workbench 101a arranged at the bottom thereof, support legs 101b arranged on both sides of the workbench 101a, a cutting groove 101c arranged through the surface of the workbench 101a, a unloading notch 101d arranged on both sides of the cutting groove 101c, a pair of positioning strips 101e arranged on the other side of the cutting groove 101c, and a dovetail strip 101f arranged on one side of the upper end of the support platform 101.

[0031] Furthermore, the eccentric circle 202 includes a pair of first limiting strips 202a arranged around the outer wall thereof.

[0032] Furthermore, the moving block 203 includes a connecting rod 203a disposed at the bottom thereof, and a mounting plate 203b disposed at the bottom of the connecting rod 203a.

[0033] Furthermore, the waist-shaped rail 204 includes a pair of second limiting strips 204a arranged around its outer wall, a dovetail groove 204b arranged through one side of the end face of the waist-shaped rail 204, a swing arm 204c arranged on the side wall of the waist-shaped rail 204, and an ejection assembly 204d arranged on one side of the swing arm 204c.

[0034] Furthermore, the ejection assembly 204d includes a limiting rod 204d-1, a rubber block 204d-2 sleeved on the end of the limiting rod 204d-1, and a spring 204d-3 sleeved on the outer wall of the limiting rod 204d-1.

[0035] Furthermore, the axial hole of the eccentric circle 202 is fixedly connected to the axial end of the motor 201; the dovetail bar 101f cooperates with the dovetail groove 204b; and the limiting rod 204d-1 is fixedly connected to one side of the lower end of the swing arm 204c.

[0036] Furthermore, the abutment block 102 is fixedly connected to the workbench 101 a by bolt fastening on one side thereof.

[0037] It should be noted that the support platform 101 is C-shaped in side view. For the convenience of description, the opening of the C is set to face outwards, otherwise it faces inwards. The bottom panel of the support platform 101 is a workbench 101a, and the top panel is used as a support platform for the motor 201. Four symmetrically distributed support legs 101b are fixed on both sides of the workbench 101a. Bolt holes are opened on the support legs 101b, which can be directly placed on the table or fixed on the table by bolts.

[0038] Below the saw blade of the cutting machine M, a through cutting groove 101c is provided on the surface of the workbench 101a, so that the cutting machine M can cut the wooden board more completely.

[0039] At the position adjacent to the cutting groove 101c, the two sides of the working table 101a are provided with relatively large and symmetrically distributed unloading notches 101d, and the wood boards can fall from the unloading notches 101d after being cut, providing space for the next wood board cutting. Two symmetrically distributed positioning strips 101e are also fixed on the outer surface of the working table 101a, which can limit the feeding of the wood boards and prevent them from deviating during cutting.

[0040] Preferably, the spacing of the positioning strips 101e can be adjusted according to actual needs, and the fixing method between the positioning strips 101e and the workbench 101a includes but is not limited to bolt connection, latch connection, and snap-fit ​​connection.

[0041] Preferably, a motor 201 is fixed on the panel at the top of the workbench 101a, with the shaft end of the motor 201 facing outwards. A dovetail bar 101f is also fixed on the end surface of the top panel facing outwards, and the dovetail bar 101f can cooperate with the dovetail groove 204b and the two are movably connected, so that the waist rail 204 can move along the extension direction of the dovetail bar 101f.

[0042] Preferably, an axial hole is opened on the eccentric circle 202, and the shaft end of the motor 201 passes through the hole and is fixedly connected to the eccentric circle 202. A pair of first limit strips 202a are also fixed on the outer periphery of the two end surfaces of the side wall of the eccentric circle 202, and the moving block 203 is sleeved on the eccentric circle 202, which can prevent the moving block 203 from detaching from the eccentric circle 202, and the eccentric circle 202 and the moving block 203 are movably connected.

[0043] Preferably, the two sides of the moving block 203 are straight surfaces, which are square in this embodiment, but are not limited to waist-shaped or other shapes. Two connecting rods 203a are fixed at the bottom of the moving block 203. The connecting rods 203a are columnar and completely penetrate the bottom of the inner wall of the waist-shaped rail 204. Therefore, the moving block 203 can move up and down inside the waist-shaped rail 204. In addition, a pair of second limiting strips 204a are fixed at the openings on both sides of the inner wall of the waist-shaped rail 204. The second limiting strips 204a are also waist-shaped, which can prevent the moving block 203 from escaping.

[0044] A mounting plate 203b is also fixed at the bottom of the connecting rod 203a, which can be used to install the cutting machine M. The cutting machine M is fixedly connected to the mounting plate 203b. When the moving block 203 moves up and down, the cutting machine M and its saw blade can be moved up and down.

[0045] Preferably, when the eccentric circle 202 rotates, it can drive the waist-shaped rail 204 to move horizontally, and the moving block 203 will move up and down at this time. Therefore, the saw blade presents a downward and horizontal compound sawing movement, which greatly improves the sawing range of the cutting machine M and increases the applicability to wooden boards of different widths.

[0046] Preferably, a through and transverse dovetail groove 204b is provided below the inner end surface of the waist-shaped rail 204. In addition, a swing arm 204c is fixed on the side wall of the waist-shaped rail 204. Whether the swing arm 204c is on the left or right side of the waist-shaped rail 204 depends on the direction of the rotating shaft of the motor 201. In this embodiment, the swing arm 204c is fixed on the right side of the waist-shaped rail 204, that is, the rotating shaft of the motor 201 rotates clockwise, which is also the direction when the cutting machine M cuts. When the motor 201 reverses, the cutting direction of the cutting machine M is opposite.

[0047] Preferably, an ejection assembly 204d is fixed to the bottom of one side of the swing arm 204c close to the support platform 101. Specifically, one end of the limit rod 204d-1 is fixedly connected to the swing arm 204c, and the other end is provided with a limit ring for limiting the rubber block 204d-2. The rubber block 204d-2 is cylindrical, with a cylindrical cavity inside, and can move along its axis on the limit rod 204d-1. Similarly, a limit ring is also provided at the opening of the cavity of the rubber block 204d-2 to prevent the rubber block 204d-2 from escaping from the limit rod 204d-1 during movement. In addition, a spring 204d-3 is also sleeved on the limit rod 204d-1, and the spring 204d-3 acts on the rubber block 204d-2 and pushes the rubber block 204d-2 to the farthest end of the limit rod 204d-1.

[0048] When cutting, the ejection assembly 204d can squeeze the wooden board laterally, cooperating with the left and right limiters of the positioning strip 101e to prevent the wooden board from moving forward and backward during cutting. After the cutting work is completed, the wood is ejected under the action of the spring 204d-3.

[0049] Preferably, the abutment block 102 can move forward and backward at the discharge notch 101d and be temporarily fixed by lateral bolts to facilitate determination of the cutting length of the wooden board.

[0050] Preferably, the motor 201 can be a servo motor to facilitate setting the rotation speed, or a reducer, such as a planetary reducer, can be installed at the shaft end of the motor 201.

[0051] When in use, a person needs to put the wooden board between the positioning strips 101 e and push it toward the abutment block 102 .

[0052] In order to facilitate the description of the motion state of the eccentric circle 202, a point P is marked at the large end of the eccentric circle 202. When the point P is at the upper end, the saw blade is away from the cutting groove 101c, and the person pushes the wooden board to the abutment block 102;

[0053] Then the motor 201 rotates clockwise, and the point P moves to the right. At this time, the saw blade cuts from the right side. The motor 201 continues to rotate, and the point P moves from the right to the left. At this time, the saw blade completes the sawing and sawing action from right to left. At the same time, the rubber block 204d-2 approaches and moves to the side of the wooden board and squeezes it. The spring 204d-3 is gradually compressed. As the saw blade reaches the left side, the wooden board is cut, and the potential energy of the spring 204d-3 is released, and the cut wood is ejected.

[0054] Then point P moves to the top, the saw blade is lifted, the staff can continue to feed the material, and the swing arm 204c is reset accordingly. This reciprocating operation can realize the cutting and unloading of the board, greatly reducing the fatigue of the staff.

[0055] In summary, this design improves the cutting range of wooden boards of different widths. While automatically cutting the wooden boards, it can also temporarily fix the wooden boards while they are being cut. It also realizes automatic unloading of the cut wood, so that personnel only need to perform feeding work, greatly reducing work intensity and time costs.
