[0049] Among them, the cutting mechanism 3, the limiting mechanism 5, the material cutting mechanism and the fixing member 4 can all be controlled by the control system.

[0050] Moreover, the control system can be a conventional control unit such as a PLC control unit, the cutting mechanism 3 is a conventional structure, and in addition to the saw blade, it can also include a saw blade housing, a saw blade drive motor, etc., and the fixing part 4 can be a conventional electric clamp.

[0051] In this embodiment, during the cutting process of the wood, the wood is transported to the cutting mechanism 3 through a plurality of conveying rollers 2. During the conveying process, the front end of the wood gradually abuts against the limiting mechanism 5. The limiting mechanism 5 can limit the cutting length of the wood and can adjust the cutting length of the wood as needed. Then the conveying rollers 2 stop running and the fixing parts 4 fix the wood. Finally, the cutting mechanism 3 cuts the wood. The cut wood can be unloaded from the machine body 1 through the unloading mechanism 6. Compared with the prior art, the utility model can facilitate the automatic processing of wood and facilitate the unloading of wood after cutting, which effectively improves the working efficiency of the automatic wood cutter.

[0052] Embodiment 2:

After the second baffle 53 moves, it approaches the first baffle 50, thereby squeezing the trigger switch 54. The trigger opening tube is triggered after being squeezed and a signal is fed back to the control system. After receiving the signal, the control system controls the conveying rollers 2 to stop running, and at the same time drives the first baffle 50 to move, thereby separating the front end of the wood from the limiting mechanism 5. Then the fixing part 4 fixes the wood, and finally the cutting mechanism 3 cuts the wood. After the wood is cut, the unloading mechanism 6 unloads the wood from the machine body 1. The initial position of the first baffle 50 can also be preset through the control system to adjust the cutting length of the wood. Compared with the prior art, the utility model further improves the degree of automation of the automatic wood cutter.

[0061] Embodiment 4:

[0062] The present embodiment provides an automatic wood breaking machine, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features: the unloading mechanism 6 also includes: a unloading frame 60, one end of which is movably connected to the machine body 1, and the side of the unloading frame 60 is arc-shaped. The unloading frame 60 can be driven by a telescopic cylinder 61 to lift and rotate; a blocking rod 62, which is movably arranged on the machine body 1 and located at the front side of the unloading frame 60, and a buffer column 7 is arranged at the bottom of the blocking rod 62.

[0063] Moreover, the unloading rack 60 includes two arc-shaped side rods and a top beam rod. When the unloading rack 60 is in a low position, the two side rods are located below the conveying roller 2. The telescopic cylinder 61 is a conventional structure. One end of the telescopic cylinder 61 is movably connected to the machine body 1, and the other end is movably connected to one of the two side rods. The telescopic cylinder 61 can be controlled by a control system.

[0064] In this embodiment, after the wood is cut, the telescopic cylinder 61 operates to drive the unloading rack 60 to rotate and rise, thereby lifting the wood on the conveyor roller 2 and unloading the body 1. After the wood is unloaded, the blocking rod 62 falls first and finally moves to one side of the body 1. The buffer column 7 at the bottom of the blocking rod 62 can effectively reduce the vibration generated during the unloading process of the wood, thereby preventing the body 1 from being damaged due to vibration, and improving the service life of the body 1.

[0065] Embodiment 5:

[0066] This embodiment provides an automatic wood breaking machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the buffer column 7 also includes: a fixed column 70, which is arranged on the machine body 1, and a buffer chamber 71 and a spring chamber 76 chamber 72 are arranged in the fixed column 70; a movable column 73, which is arranged on the fixed column 70 and can move up and down, and a piston portion 74 is arranged on the movable column 73, and a spring 76 groove 75 is arranged at the bottom end of the movable column; a spring 76, which is arranged in the spring chamber 72;

[0067] Among them, the piston part 74 is located in the buffer chamber 71, and there is a gap between the piston part 74 and the inner wall of the buffer chamber 71. The buffer chamber 71 and the spring 76 chamber 72 are separated from each other. The bottom end of the movable column 73 is located in the spring 76 chamber 72, and the top end of the spring 76 is located in the spring 76 groove 75. The top end of the movable column 73 is movably connected to the material blocking rod 62.

[0068] Moreover, the buffer chamber 71 and the spring chamber 76 72 are separated by the surface of the bottom end of the movable column 73 and a conventional seal. The top end of the movable column 73 is movably connected to the material stopping rod 62 in a conventional manner, such as installing a connecting block at the bottom of the material stopping rod 62, and a movable groove is provided on the connecting block. The top end of the movable column 73 is connected to a rotating shaft, and the rotating shaft is movably connected to the movable groove, so that the movable block can rotate and move linearly relative to the material stopping rod 62.

[0069] In this embodiment, when the buffer column 7 is impacted, the movable column moves downward, the piston portion 74 moves accordingly, and the buffer chamber 71 is filled with a buffer. The buffer can flow through the gap between the piston portion 74 and the inner wall of the buffer chamber 71, thereby buffering the impact through fluid resistance. At the same time, the spring 76 is also compressed with the movement of the movable column 73. After the impact dissipates, the spring 76 can drive the movable column 73 to reset. By separating the buffer chamber 71 and the spring 76 chamber 72, the spring 76 can be prevented from contacting the buffer, thereby increasing the service life of the spring 76, thereby ensuring the buffering effect of the buffer column 7, reducing the vibration generated during the wood unloading process, and increasing the service life of the machine body 1.
