[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 As shown in the figure, a cutting device for bamboo and wood processing according to an embodiment of the present invention includes a base 1, a column 10 fixedly provided at the rear end of the top surface of the base 1, a cutting mechanism 2 installed on the column 10, the cutting mechanism 2 including a lever arm 20 rotatably connected to the column 10, a cutting blade 21 rotatably provided on the lever arm 20, and a driving component 3 for driving the cutting blade 21 to work on the lever arm 20. An operating table 4 is provided at the front end of the top surface of the base 1, the operating table 4 has a clearance area 40 adapted to the cutting blade 21, a vertical plate 41 is provided on the operating table 4, and a calibration unit 5 is installed on the vertical plate 41. The calibration unit 5 can be adjusted and locked. During cutting, the bamboo and wood material is calibrated with the calibration unit 5 to achieve cutting positioning.

[0019] During use, the adjustable and locked calibration unit 5 enables precise positioning of bamboo and wood materials, avoiding human positioning errors; the cutting mechanism 2 is rotatably connected to the column 10, and with the clearance range 40 of the operating table 4, the cutting process is stable and efficient; the overall structure is compact and suitable for the cutting needs of various specifications of bamboo and wood materials, making it more practical.

[0020] The drive assembly 3 includes a power source 30 fixed on the lever arm 20, which is driven by the rotating shaft of the cutting blade 21 through a linkage element.

[0021] In use, the cutting blade 21 is rotatably mounted on the free end of the lever arm 20 via a rotating shaft. The drive assembly 3 directly drives the rotating shaft of the cutting blade 21 via a power source 30 (such as a motor) and a linkage element. The linkage element can be a chain and gear combination structure, with a drive gear installed at the output shaft end of the power source 30, and the cutting blade 21 rotatably connected to the free end of the lever arm 20 via the rotating shaft, and a driven gear installed at the end of the rotating shaft. The drive gear and the driven gear are driven by a chain meshing transmission. Alternatively, a belt and pulley combination structure can be used, with the drive pulley at the output end of the power source 30 connected to the driven pulley on the rotating shaft of the cutting blade 21 via a transmission belt. This type of linkage method has high transmission efficiency, reduces energy loss, ensures stable rotation speed of the cutting blade 21, and thus improves cutting quality. In addition, the overall structure is simple, and the components are easy to disassemble and assemble, facilitating daily maintenance.

[0022] A blade cover 22 is installed on the outside of the cutting blade 21, and an adjustable protective plate 23 is also installed on the blade cover 22.

[0023] During use, the blade cover 22 provides basic protection for the cutting blade 21, preventing cutting debris from flying; the adjustable protective plate 23 can adjust the protection range according to the size of the bamboo and wood material, further improving operational safety and adapting to cutting scenarios of materials of different thicknesses. The adjustable protective plate 23 is designed to be hinged to one end of the blade cover 22 via a pivot. When no external force is applied, friction can firmly lock the current position of the protective plate, keeping it stably at the set protection angle (such as retracting it to fit the surface of the blade cover 22, or opening it outward at a certain angle to cover the blade). When adjustment is required, the operator only needs to push the protective plate by hand (the protective plate is made of transparent material such as acrylic). After the external force overcomes the frictional damping, the protective plate can rotate flexibly around the pivot to adjust to the protection position that matches the thickness of the bamboo or wood material. After being released, it can be automatically fixed by the damping, which ensures both the convenience of adjustment and the stability in the non-adjustment state.

[0024] The rear end of the lever arm 20 is connected to a spring member 24, and the other end of the spring member 24 is fixedly connected to the lower end of the column 10. The front end of the lever arm 20 is also connected to a control lever 25.

[0025] When in use, the spring component 24 can automatically drive the power arm 20 to reset after cutting, reducing manual operation steps and labor intensity; the control lever 25 makes it easy for operators to control the downward pressure and speed of the cutting mechanism 2, improving the ease of operation.

[0026] The calibration unit 5 includes a substrate 50 and a calibration component 51 that is detachably mounted on the substrate 50.

[0027] In use, the calibration unit 5 adopts a combination structure of base plate 50 and detachable calibration component 51. Different specifications of calibration component 51 (such as positioning plates of different lengths or shapes) can be replaced according to cutting requirements, which enhances the versatility of the device and reduces equipment replacement costs.

[0028] The top surface of the substrate 50 is formed with a first threaded post 52, the calibration component 51 has a fastening hole 53 adapted to the first threaded post 52, a fastening washer 54 is also sleeved on the outside of the first threaded post 52, and a lever-type fastener 55 is connected to the upper end of the first threaded post 52.

[0029] When using the calibration piece 51, first align the fastening hole 53 of the calibration piece 51 with the first threaded post 52 on the top surface of the substrate 50 and insert it so that the calibration piece 51 fits against the surface of the substrate 50; then, put the fastening washer 54 on the first threaded post 52 to ensure that the washer is flat and pressed against the top surface of the calibration piece 51; finally, screw the lever fastener 55 into the upper end of the first threaded post 52, and rotate the lever (manual operation without tools) to drive the washer to press the calibration piece 51 until the calibration piece 51 is firmly fixed on the substrate 50, thus completing the installation; when disassembling, rotate the lever fastener 55 in the opposite direction, remove the washer, and the calibration piece 51 can be pulled out directly. The whole process does not require complicated tools, is convenient to operate, and can ensure the stability of the position of the calibration piece 51 after installation. The calibration component 51 is quickly disassembled and positioned on the substrate 50 by the cooperation of the first threaded post 52, the fastening hole 53, the fastening washer 54 and the lever-type fastener 55. The adjustment process is simple and efficient, ensuring that the calibration component 51 is accurately and stably positioned.

[0030] The top surface of the substrate 50 is also provided with a fixing member 56, which includes a fixed end 57 and a movable end 58 hinged to the fixed end 57. The fixing member 56 is clamped and fixed to the upright plate 41 through the clamping fit formed by the fixed end 57 and the movable end 58.

[0031] When in use, the fixed end 57 and the movable end 58 of the fastener 56 are fixed to the upright plate 41 by clamping, which can flexibly adjust the height or horizontal position of the calibration unit 5 on the upright plate 41 to adapt to the positioning needs of bamboo and wood materials of different sizes, and the connection is firm and not easy to loosen.

[0032] The fixed end 57 has a second threaded post 6 and a fastening knob 60 is connected to the outside of the second threaded post 6. The movable end 58 has a through groove that is adapted to the second threaded post 6.

[0033] In use, the second threaded post 6 cooperates with the fastening knob 60 and the through groove of the movable end 58 to achieve quick locking and unlocking of the fixing part 56, which is convenient to operate and ensures that the calibration unit 5 is stably fixed after adjustment, further improving the positioning accuracy. Among them, the through groove is a long strip-shaped trajectory groove, and the length direction of the trajectory groove is adapted to the trajectory of the movable end 58 rotating around the hinge point, so as to avoid interference between the movable end 58 and the second threaded post 6 during the rotation process.

[0034] An adjustment mechanism for adjusting the horizontal front-to-back position of the operating table 4 is also provided between the base 1 and the operating table. The adjustment mechanism includes a first fixed seat 7 fixed at the center of the top surface of the base 1. An adjustment screw 70 extending in the front-to-back direction is rotatably inserted in the first fixed seat 7. One end of the adjustment screw 70 extends through to the outside of the first fixed seat 7 and is connected to an adjustment knob 75. The bottom surface of the operating table 4 is provided with a threaded mating block 71 that is adapted to the thread of the adjustment screw 70. Two second fixed seats 72 are provided on the left and right sides of the first fixed seat 7 on the top surface of the base 1. Each second fixed seat 72 is fixed with a guide rod 73 extending in the front-to-back direction. The bottom surface of the operating table 4 is provided with guide blocks 74 that are slidably adapted to the two guide rods 73 respectively.

[0035] In use, by adding an adjustment mechanism that can be adjusted in the front-to-back direction, the horizontal distance between the operating table 4 and the cutting mechanism 2 can be flexibly adjusted: when the adjustment knob 75 is turned, the adjustment screw 70 rotates in the first fixed seat 7. The adjustment screw 70 has an external thread and the threaded mating block 70 has a threaded mating hole that matches the external thread. Through the thread transmission between the adjustment screw 70 and the threaded mating block 71, the operating table 4 is driven to slide back and forth along the guide rod 73. The cooperation between the guide block 74 and the guide rod 73 ensures that the table moves smoothly without deviation. This structure can adapt to the cutting needs of bamboo and wood materials of different lengths. Especially for scenarios where different cutting allowances need to be reserved or the cutting starting point position needs to be adjusted, it can be achieved by precisely adjusting the front and back positions of the table. There is no need to frequently replace the calibration part 51, which further improves the versatility and operational flexibility of the device. The adjustment process is convenient and labor-saving, and the structure is stable and reliable.

[0036] The specific working process of this utility model is as follows: When using the bamboo and wood processing cutting device, first, according to the length of the bamboo and wood material and the cutting starting point requirements, adjust the front and back position of the operating table 4 through the adjustment mechanism, rotate the adjustment knob 75, so that the adjustment screw 70 rotates in the front and back direction in the first fixed seat 7, and drive the operating table 4 to slide back and forth along the guide rod 73 through the threaded mating block 71 until the distance between the table and the cutting mechanism 2 is adapted to the material requirements; then, according to the material cutting accuracy requirements, adjust the height or horizontal position of the calibration unit 5 on the upright plate 41 by rotating the movable end 58 of the fixing part 56 around the hinge point (using the long strip track groove to avoid interference with the second threaded post 6), and tighten the fastening knob 60 to complete the locking; then select the appropriate calibration part 51, fit its fastening hole 53 into the first threaded post 52 of the base plate 50, put on the fastening washer 54, and tighten the lever to fix it; The drive assembly 3 is activated, and the power source 30 drives the cutting blade 21 to rotate through linkage components such as chain gears or belt pulleys. At the same time, the laser generating unit emits a laser beam and calibrates with the clearance interval 40 to indicate the cutting position. The operator positions the bamboo or wood material against the calibration piece 51, holds the control lever 25 and lowers the pressure arm 20, causing the cutting blade 21 to rotate along the column 10 and cut the material through the clearance interval 40. There is a limiting structure between the lever 20 and the column 10 to limit the maximum downward pressure path of the lever 20, thereby limiting the maximum downward pressure path of the cutting blade 21. During the cutting process, the blade cover 22 and the adjustable protective plate 23 prevent debris from flying. After the cutting is completed, the lever is released, and the spring 24 automatically resets the power arm 20, completing one cutting operation.
