[0037] Combination Figure 1-5As shown in the figure, this disclosure provides a bamboo rotary cutting device, including: a support slide 100, with a clamping frame 101 at one end, and a rotary cutting slide rail 102 at the upper part of the support slide 100; a sliding blade holder 200, slidably disposed on the rotary cutting slide rail 102 on one side of the bottom of the clamping frame 101; a hinged blade holder 201, hingedly disposed within the sliding blade holder 200, and a rotary cutting blade 202 is horizontally disposed within the hinged blade holder 201; a support slide rail 300, one end of which is hinged to the bottom of the support slide 100 near the clamping frame 101, and the other end of the bottom of the support slide 100 is provided with a lifting rod 301, the support slide 100 and the lifting rod 301 are hingedly connected, and the hinged blade holder 201 is slidably disposed on the support slide rail 300.
[0038] Using the bamboo rotary cutting device provided in this embodiment, the support slide 100 can be fixed on the bottom surface to support the clamping frame 101. Two clamping frames 101 are respectively arranged on both sides of one end of the support slide 100. The clamping frames 101 can clamp and rotate bamboo or wood. A rotary cutting slide rail 102 is provided on the upper part of the support slide 100 on one side of the clamping frame 101. The sliding blade holder 200 can slide freely on the rotary cutting slide rail 102, allowing the sliding blade holder 200 to move away from or closer to the clamping frame 101, thus facilitating rotary cutting of the wood. A hinged blade holder 201 is also hinged to the sliding blade holder 200. The hinged blade holder 201 is located inside the sliding blade holder 200, and its two sides are rotatably connected to the two sides of the sliding blade holder 200. By rotating the hinged blade holder... The angle of the rotary cutting blade 202 can be adjusted to meet the rotary cutting requirements of blanks of different thicknesses. The support slide rail 300 has a long strip structure. One end of the support slide rail 300 is hinged to the support slide 100 at the bottom of the clamping frame 101, and the other end of the support slide rail 300 is connected to the lifting rod 301. The other end of the lifting rod 301 is hinged to the bottom of the support slide 100. By adjusting the vertical extension and retraction of the lifting rod 301, one end of the support slide rail 300 can move up and down, thereby adjusting the tilt angle of the support slide rail 300. The hinged blade holder 201 can slide on the support slide rail 300. In this way, by controlling the angle of the support slide rail 300, the angle of the cutting blade 211 on the hinged blade holder 201 can be controlled, thereby adapting to the rotary cutting of blanks of different thicknesses and ensuring the stability and accuracy of the rotary cutting process.
[0039] Optionally, a drive screw 103 is provided on the side of the support slide 100 away from the clamping frame 101, and the drive screw 103 is threadedly connected to the sliding tool holder 200.
[0040] Thus, a drive screw 103 is provided on the upper part of the support slide 100 away from the clamping frame 101. The drive screw 103 extends along the direction of the rotary cutting slide rail 102 and is threadedly connected to the sliding tool holder 200. By rotating the drive screw, the sliding tool holder 200 can be moved on the rotary cutting slide rail 102 to achieve precise position adjustment, thereby controlling the thickness accuracy and efficiency in rotary cutting.
[0041] Optionally, the hinged tool holder 201 has a rotary cutting groove 203 on the hinged axial side to accommodate the clamping frame 101. A rotary cutting blade 202 is provided on the hinged tool holder 201, and the rotary cutting blade 202 is positioned facing into the rotary cutting groove 203. A pressure ruler frame 400 is hinged to the side of the hinged tool holder 201 away from the rotary cutting groove 203. A pressure ruler strip 401 is provided at the bottom of the side of the pressure ruler frame 400 near the rotary cutting blade 202, and the pressure ruler strip 401 is positioned facing the blade edge of the rotary cutting blade 202.
[0042] Thus, the hinged blade holder 201 has rotary cutting grooves 203 on both sides, and the sliding blade holder 200 also has grooves on its sides. This allows the material on the clamping frame 101 to enter the rotary cutting grooves 203. The cutting edge of the rotary cutting blade 202 is positioned within the rotary cutting grooves 203. By swinging the clamping frame 101, the cutting edge angle of the rotary cutting blade 202 can be adjusted, thereby allowing for precise rotary cutting of slabs of different thicknesses. The hinged blade holder 201 is located away from the rotary cutting grooves 203. A pressure gauge frame 400 is hinged on one side. A pressure gauge strip 401 is provided at one end of the pressure gauge frame 400 near the rotary cutting groove 203. The end of the pressure gauge strip 401 is near the rotary cutting blade 202. The thickness of the slab can be controlled by the distance between the pressure gauge strip 401 and the rotary cutting blade 202. The pressure gauge strip 401 can effectively press the slab after rotary cutting by the rotary cutting blade 202, which can prevent the slab skin from being damaged after rotary cutting and ensure that the pressure on both sides of the slab skin is balanced during rotary cutting, thereby stabilizing the rotary cutting quality of the slab.
[0043] Optionally, the pressure gauge frame 400 and the hinged knife holder 201 are connected by an eccentric shaft frame 500, which is slidably mounted on the hinged knife holder 201.
[0044] In this way, the pressure gauge frame 400 and the hinged blade holder 201 are connected by an eccentric shaft frame 500. The eccentric shaft frame 500 can drive the pressure gauge frame 400 to slide on the hinged blade holder 201. This allows control over the distance between the pressure gauge strip 401 on the pressure gauge frame 400 and the rotary cutting blade 202, thus enabling adjustment of slabs of different thicknesses. This allows for the accumulation of slabs with different thicknesses, achieving more flexible thickness control and ensuring rotary cutting accuracy and stability.
[0045] Optionally, a tool spacing screw 205 is threadedly connected to one side of the upper part of the articulated tool holder 201; one end of the tool spacing screw 205 is rotatably connected to the eccentric shaft holder 500.
[0046] Thus, the upper part of the articulated tool holder 201 is connected to a tool spacing screw 205 via a thread. One end of the tool screw is rotatably connected to the eccentric shaft bracket 500. By rotating the tool spacing screw 205, the position of the eccentric shaft bracket 500 on the articulated tool holder 201 can be finely adjusted, thereby precisely controlling the distance between the pressure strip 401 and the rotary cutter 202.
[0047] Optionally, a height threaded rod 501 is vertically provided on the upper part of the pressure gauge frame 400 away from the eccentric shaft frame 500, and the height threaded rod 501 is pressed onto the upper part of the sliding tool holder 200.
[0048] In this way, a height threaded rod 501 is vertically set on the side of the pressure gauge frame 400 away from the eccentric shaft frame 500. By rotating the height threaded rod 501, the tilt angle of the pressure gauge frame 400 can be adjusted, so that the height of the pressure gauge strip 401 is flush with the height of the rotary cutting blade 202. This ensures that the pressure gauge strip 401 is always in close contact with the surface of the blank during the rotary cutting process, which can better press the blank and avoid the warping or tearing of the blank skin during rotary cutting due to height differences. This further improves the uniformity of rotary cutting and the surface finish.
[0049] Optionally, an eccentric shaft 502 is rotatably disposed inside the eccentric shaft bracket 500, and an eccentric rod 503 is disposed on one side of the eccentric shaft 502. The pressure gauge bracket 400 is rotatably sleeved on the eccentric rod 503. An eccentric adjustment rod 504 is fixedly disposed in the middle of the eccentric rod 503. A lower fine adjustment screw 505 is threadedly connected to the middle of the eccentric adjustment rod 504. The lower fine adjustment screw 505 contacts the inner bottom of the pressure gauge bracket 400. An upper fine adjustment screw 506 is threadedly connected to the upper part of the pressure gauge bracket 400, and the upper fine adjustment screw 506 is pressed against the eccentric adjustment rod 504.
[0050] Thus, an eccentric shaft 502 is rotatably mounted inside the eccentric shaft bracket 500, and an eccentric rod 503 is eccentrically mounted on one side of the eccentric shaft 502. The pressure gauge bracket 400 is rotatably sleeved on the eccentric rod 503. An eccentric adjustment rod 504 is fixed in the middle of the eccentric rod 503. A lower fine-tuning screw 505 is threadedly connected to the middle of the eccentric adjustment rod 504. The lower end of the lower fine-tuning screw 505 is pressed against the inner bottom of the pressure gauge bracket 400. An upper fine-tuning screw 506 is threadedly connected to the outer top of the pressure gauge bracket 400, and one end of the upper fine-tuning screw 506 is pressed against the eccentric adjustment rod. On 504, the eccentric adjustment rod 504 can be stably fixed on the pressure gauge frame 400 by the upper fine adjustment screw 506 and the lower fine adjustment screw 505. The position of the eccentric adjustment rod 504 on the pressure gauge frame 400 can be controlled by adjusting the upper fine adjustment screw 506 and the lower fine adjustment screw 505. By adjusting the position of the eccentric adjustment rod 504, the eccentricity of the pressure gauge frame 400 can be finely adjusted, thereby finely adjusting the distance between the pressure gauge strip 401 and the rotary cutting blade 202, further ensuring the precise alignment of the pressure gauge strip 401 and the rotary cutting blade 202 during the rotary cutting process.
[0051] Optionally, a push screw 402 is provided laterally at the bottom of the pressure ruler frame 400, and the push screw 402 is rotatably connected to the pressure ruler strip 401.
[0052] In this way, the push screw 402 is horizontally arranged at the bottom of the pressure frame 400. The push screw 402 is threadedly connected to the pressure frame 400. By rotating the push screw 402, the position of the pressure frame 400 can be adjusted horizontally. This can control the horizontal distance between the pressure strip 401 and the rotary cutting blade 202, thereby controlling the distance between the pressure strip 401 and the rotary cutting blade 202, which makes it convenient to press the rotary-cut slab.
[0053] Optionally, clamping rollers 104 are respectively provided on both sides of the upper part of the clamping frame 101, and the clamping rollers 104 are rotatably mounted on the clamping frame 101.
[0054] Thus, there are two clamping frames 101 respectively arranged on both sides of the support slide 100. Each clamping frame 101 is equipped with a clamping roller 104. The two clamping rollers 104 are arranged opposite each other to clamp and rotate the material. The material can be rotary cut by bringing the rotary cutter 202 close to the material.
[0055] Optionally, a guide plate 206 is provided on the upper part of the articulated blade holder 201, a conveyor belt 207 is provided at the end of the guide plate 206, a cutting frame 208 is provided at the end of the conveyor belt 207, a cutting roller 209 is provided at the bottom of the cutting frame 208, a blade roller 210 is provided on the upper part of the cutting roller 209, and a cutting blade 211 is provided on the upper part of the blade roller 210 along the length direction.
[0056] In this way, the guide plate 206 on the upper part of the hinged blade holder 201 can allow the rotary-cut slab to pass smoothly, and the conveyor belt 207 at the end of the guide plate 206 can transport the rotary-cut slab and transport the slab into the cutting frame 208. The bottom of the cutting frame 208 is provided with a cutting roller 209, and a blade roller 210 is rotatably provided on the upper part of the cutting roller 209. The cutting blade 211 on the blade roller 210 can contact the cutting roller 209. In this way, the rotary-cut slab can be cut by the blade roller 210 and the cutting blade 211.
