[0002] With the rapid development of the economy, wooden furniture and office supplies are becoming more and more popular. The wood industry is booming. There are few natural wood products in the market, and most of them are synthetic wood products. More and more consumers prefer pure wooden furniture. In the process of wood board processing, the wood board cutting equipment is an essential key tool. Currently, the commonly used one is the CNC wood board cutting equipment. The publication number CN209903396U discloses a CNC wood board cutting equipment, including a cutting unit and an operation platform. The cutting unit includes a numerical control box, a connecting rod, a support rod, a bearing, a hydraulic cylinder, a hydraulic rod, a motor, a cutting blade and a protective cover. The operation platform includes a bracket, a cross bar, a transmission shaft, a storage box and a limit buckle. The top of the numerical control box is fixedly connected with a connecting rod, and the connecting rod is in an inverted L shape. The end of the connecting rod is telescopically connected with a support rod, and the other side of the support rod is detachably connected with a bearing. A hydraulic cylinder is installed at the bottom of the bearing, and a hydraulic rod is fixedly installed at the bottom of the hydraulic cylinder. The other side of the hydraulic rod is fixedly connected with a motor. In the actual application of the above technology, when cutting the wood board, there is no good limiting structure, and the equipment itself cannot fix the wood board. During the processing, the wood board is prone to move or deform, affecting the cutting result, and improvement is needed. Content of the Utility Model

[0030] Embodiment 1

[0031] The present utility model provides a technical solution: a CNC cutting device with an anti-offset mechanism, including a table body 1. A first fixing frame 2 and a second fixing frame 11 are fixedly installed on the surface of the table body 1. Rotating shafts 3 are rotatably connected to the surfaces of the first fixing frame 2 and the second fixing frame 11. Friction rollers 4 are fixedly installed on the surfaces of the rotating shafts 3. A motor 5 is fixedly installed on the surface of the table body 1. A bidirectional lead screw 6 is fixedly installed on the surface of the motor 5. A moving block 7 is threadedly connected to the surface of the bidirectional lead screw 6. A limiting plate 8 is fixedly installed on the surface of the moving block 7. A support 9 is fixedly installed on the surface of the table body 1. A cutting knife 10 is fixedly installed on the surface of the support 9. The number of the limiting plates 8 is two groups, and the two groups of limiting plates 8 are equidistantly distributed on the surface of the table body 1. By driving the lead screw to rotate through the motor 5, the distance between the two groups of limiting plates 8 is adjusted, so as to limit the movement of the wooden board. The two groups of limiting plates 8 can fix and limit the wooden board from two directions. The shape of the limiting plate 8 is L-shaped. The L-shaped limiting plate 8 can ensure the limitation of the side surface of the wooden board and also limit the upper surface of the wooden board, effectively preventing the wooden board from shaking during cutting and affecting the cutting result. A leakage hole 12 is opened on the surface of the table body 1. A support frame 13 is fixedly installed at the bottom end of the table body 1. When the CNC cutting device cuts the wooden board, a large volume of debris will be generated. The leakage hole 12 can facilitate the cleaning of the surface of the table body 1. The support frame 13 at the bottom end of the table body 1 can provide better support force for the CNC cutting device, making the CNC cutting device more stable during use. The cutting knife 10 is located between the first fixing frame 2 and the second fixing frame 11. The friction rollers 4 on the surfaces of the first fixing frame 2 and the second fixing frame 11 can drive the wooden board to move, so as to ensure that the wooden board passes through the cutting knife 10.

[0032] Embodiment 2

[0033] Please refer to Figures 1-2 , a dust suction cover 14 is fixedly installed on the surface of the table body 1, a dust suction chamber 15 is fixedly installed on the side surface of the table body 1, and an air guide pipe 16 is fixedly installed between the dust suction cover 14 and the dust suction chamber 15. The dust suction chamber 15 can suck the dust generated during the cutting process from the dust suction cover 14, and store it in the dust suction chamber 15 after passing through the air guide pipe 16, thus effectively preventing the dust from entering the air and affecting the health of the operator. The dust suction chamber 15 is located directly above the cutting knife 10. When the dust suction chamber 15 is located directly above the cutting knife 10, a larger area can be used to suck the dust at the cutting position, improving the cleaning effect.

[0034] Working principle: When in use, first place the CNC cutting device on a flat position. The support frame 13 at the bottom of the body can provide better support for the CNC cutting device, making the CNC cutting device more stable during use. Then place the wooden board on the surface of the table body 1. Then turn on the motor 5, and drive the lead screw to rotate through the motor 5 to adjust the distance between the two limit plates 8. When the limit block moves to the appropriate position, the friction roller 4 on the surface of the first fixing frame 2 drives the wooden board to move forward. When passing through the cutting knife 10, turn on the dust suction chamber 15. The dust suction chamber 15 can suck the dust generated during the cutting process from the dust suction cover 14, and store it in the dust suction chamber 15 after passing through the air guide pipe 16, thus effectively preventing the dust from entering the air and affecting the health of the operator. When the dust suction chamber 15 is located directly above the cutting knife 10, a larger area can be used to suck the dust at the cutting position, improving the cleaning effect. When the CNC cutting device cuts the wooden board, larger volume debris will be generated. The leakage holes 12 can facilitate the cleaning of the surface of the table body 1.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
