[0013] Compared with the prior art, this utility model provides a bamboo cutting device for bamboo furniture production, which has the following advantages:

[0014] 1. This bamboo cutting device for bamboo furniture production moves the mounting plate, cutting assembly, and compression limiting assembly downwards by activating two first hydraulic cylinders. The clamping plate contacts the bamboo first. As the mounting plate continues to move downwards, it further compresses the compression spring. The spring force of the compression spring causes the clamping plate to squeeze and limit the bamboo, thus ensuring the stability of the bamboo cutting position and minimizing the shaking of the bamboo during cutting, thereby improving the cutting effect.

[0015] 2. This bamboo cutting device for bamboo furniture production uses a stepper motor to drive a bevel gear, which in turn drives a threaded rod to rotate. During rotation, the threaded rod moves the moving block and the bamboo as a whole to the left. After each cutting operation, the stepper motor is activated to move the bamboo to the left until the left side of the bamboo aligns with the right side of the L-shaped board. This automatic feeding eliminates the need for manual rearrangement of the bamboo, ensuring continuous cutting operations, improving processing efficiency, and simplifying user operation.

The bottom of the bamboo material 14 is attached to the top of the processing table 1.

[0025] A fixing component 15 is movably installed between the front and rear sides of the inner wall of the rectangular hole 12.

[0027] A compression limiting component 17 is fixedly installed on the bottom right side of the mounting plate 5. The compression limiting component 17 includes a rectangular frame 171. The rectangular frame 171 located to the right of the cutting blade 63 is fixedly installed on the bottom of the mounting plate 5. A rectangular block 172 extending to its bottom is movably installed inside the rectangular frame 171. A clamping plate 173 located above the bamboo material 14 is fixedly installed on the bottom of the rectangular block 172. Limiting grooves 174 are opened on both the left and right sides of the inner wall of the rectangular frame 171. A limiting block 175 is movably installed inside each of the two limiting grooves 174, with one end fixedly connected to the top of the left and right sides of the rectangular block 172 respectively. A compression spring 176 located inside the rectangular frame 171 and fixedly connected to the bottom of the mounting plate 5 is fixedly installed on the top of the rectangular block 172. The compression spring 176 has a very large elastic coefficient.

[0028] In use, the controller 7 activates two first hydraulic cylinders 4 to move the mounting plate 5, cutting assembly 6, and compression limiting assembly 17 downwards as a whole, and activates the drive motor 62 to rotate the cutting blade 63. The clamping plate 173 will initially contact the bamboo 14. As the mounting plate 5 continues to move downwards, it further compresses the compression spring 176. The elasticity of the compression spring 176 causes the clamping plate 173 to compress and limit the bamboo 14, thus ensuring the stability of the bamboo 14's cutting position and minimizing vibration during cutting, thereby improving the cutting effect. The cutting blade 63 cuts the bamboo 14 as it moves downwards, and the cut portion falls from the material drop hole 8. After a single cutting operation, the bamboo is ready for use. The two first hydraulic cylinders 4 are activated to move the mounting plate 5, cutting assembly 6, and extrusion limiting assembly 17 upwards for resetting. Then, the stepper motor 161 is activated to drive the bevel gear 163 to rotate, which in turn drives the threaded rod 10 to rotate via the driven bevel gear 164. During the rotation of the threaded rod 10, the moving block 11 and the bamboo material 14 move to the left until the left side of the bamboo material 14 is in contact with the right side of the L-shaped plate 3, thus automatically feeding the material. Then, the two first hydraulic cylinders 4 can be activated again to move the mounting plate 5, cutting assembly 6, and extrusion limiting assembly 17 downwards for cutting. No manual rearrangement of the bamboo material 14 is required, thus ensuring continuous cutting and improving processing efficiency and user convenience.

[0029] In summary, this bamboo cutting device for bamboo furniture production moves the mounting plate 5, cutting assembly 6, and compression limiting assembly 17 downwards by activating two first hydraulic cylinders 4. The clamping plate 173 initially contacts the bamboo 14. As the mounting plate 5 continues to move downwards, it further compresses the compression spring 176. The spring force of the compression spring 176 causes the clamping plate 173 to compress and limit the bamboo 14, ensuring the stability of the bamboo 14's cutting position and minimizing vibration during cutting, thus improving the cutting effect. Secondly, the stepper motor 161 drives the drive bevel gear 163 to rotate, which in turn drives the threaded rod 10 to rotate via the driven bevel gear 164. During rotation, the threaded rod 10 drives the moving block 11 and the bamboo... The bamboo material 14 moves to the left as a whole. After a single segmentation is completed, the stepper motor 161 is started to drive the bamboo material 14 to move to the left until the left side of the bamboo material 14 is in contact with the right side of the L-shaped plate 3. This automatically performs the feeding operation without the need for manual rearrangement of the bamboo material 14, thus ensuring continuous segmentation and improving processing efficiency. This also makes it more convenient for users. It solves the problem that existing bamboo segmentation devices often lack automatic feeding functions due to their simple structure, which requires manual rearrangement after a single segmentation, causing great inconvenience. Furthermore, the lack of a limit function leads to significant shaking at the cutting position during segmentation, which is detrimental to the cutting operation.
