Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0037] Reference Figures 1-10The image shows a preferred embodiment of the present invention.

[0038] The present invention provides a bamboo splitting machine for splitting bamboo tubes into multiple bamboo strips, comprising a positioning clamping structure 600, a centering structure 100, a bamboo splitting knife 201, a pushing structure 400 for pushing the bamboo tube forward, and a rotating cylinder 300. The positioning clamping structure 600, the centering structure 100, the bamboo splitting knife 201, and the rotating cylinder 300 are arranged in sequence. The positioning clamping structure 600 clamps the bamboo tube being fed, keeping the bamboo tube horizontal.

[0039] The concentric structure 100 has a concentric channel 102 for the bamboo tube to pass through. After the front end of the bamboo tube passes through the concentric structure 100, the concentric structure 100 adjusts the front end of the bamboo tube to be aligned with the bamboo splitting knife 201. The rotating cylinder 300 has a horizontally arranged hollow cavity.

[0040] The pushing structure 400 pushes the bamboo tube, which has been adjusted by the centering structure 100, forward from back to front, so that the bamboo tube passes through the bamboo splitting knife 201. As the bamboo tube passes through the bamboo splitting knife 201, the bamboo splitting knife 201 cuts the outer wall of the bamboo tube, dividing the bamboo tube into multiple bamboo pieces. The multiple bamboo pieces pass through the hollow cavity of the rotating cylinder 300 and move forward.

[0041] The bamboo splitting machine described above, which splits bamboo tubes into multiple bamboo strips, first sets the desired number of bamboo strips. Based on this setting, the splitting blade 201 is positioned at the designated location. The alignment structure 100 aligns the bamboo tube with the splitting blade 201 at the designated location. Then, the pushing structure 400 pushes the bamboo tube to split it into multiple bamboo strips. In this way, the bamboo tube can be split from the top to the bottom to form multiple bamboo strips. The overall operation is simple, realizes automated bamboo splitting, effectively improves the utilization rate of bamboo ends, and increases production efficiency.

[0042] A bamboo clamping arm 500 is provided in front of the rotating drum 300. When the front end of the bamboo strip extends from the front end of the rotating drum 300, the bamboo clamping arm 500 clamps the front end of the bamboo strip and pulls the bamboo strip out of the rotating drum 300 for feeding. This allows the split bamboo strips to be collected individually. In this way, compared with centralized collection, the bamboo strips collected individually can be directly connected to the feed port of the rough planer, eliminating intermediate steps and facilitating the overall automation layout of the production line.

[0043] The positioning and clamping structure 600 includes a clamping head and a support claw 602 that holds the bamboo tube from bottom to top, with the clamping head and support claw 602 arranged front to back. The clamping head includes two clamping claws 601 arranged vertically and clamping the bamboo tube vertically, with a clamping channel between the two clamping claws 601 for the bamboo tube to pass through. In this way, the bamboo tube can be clamped and fixed in the clamping channel by the clamping claws 601, and the support claw 602 further stabilizes the bamboo tube horizontally, making the bamboo tube more stably arranged in the clamping channel.

[0044] The concentric structure 100 includes four swing plates 101 that swing towards each other or away from each other. The four swing plates 101 are arranged in a spaced-around manner, and the four swing plates 101 enclose a concentric channel 102 for the bamboo tube to pass through.

[0045] Once the front end of the bamboo tube passes through the concentric channel 102 and is positioned towards the bamboo splitting knife 201, the four swing plates 101 clamp the bamboo tube and swing towards or away from each other to ensure that the front end of the bamboo tube is aligned with the bamboo splitting knife 201. In this way, the concentric structure 100 ensures that the center of bamboo of different thicknesses is aligned with the center of the bamboo splitting knife 201 before the bamboo is split, ensuring that the split bamboo pieces are of the same size. Furthermore, the four swing plates 101 can be controlled to swing, thereby adjusting the center position of the bamboo tube in the concentric channel 102.

[0046] The pushing structure 400 includes a horizontally arranged pushing rod 402 that pushes the bamboo tube forward from back to front. The pushing rod 402 is connected to a power element 401, which drives the pushing rod 402 to move forward or backward. The front end of the pushing rod 402 has a pushing end that abuts against the rear end of the bamboo tube. The pushing end is recessed to the rear, forming a concave spherical groove 403 for the rear end of the bamboo tube to be embedded.

[0047] A concave spherical groove 403 is formed on the pushing end, which can center the bamboo when the pushing rod 402 pushes the bamboo, and prevent the bamboo from tilting during the impact, resulting in bamboo pieces of different sizes after splitting.

[0048] A longitudinally arranged turntable 200 is provided in front of the concentric structure 100. The turntable 200 has multiple turntable holes, which are arranged at intervals around the center of the turntable 200. The rear end of the rotating cylinder 300 passes through the turntable holes. The bamboo splitting knife 201 is arranged on the turntable 200, located between the rear end of the rotating cylinder 300 and the concentric structure 100, and aligned with the turntable holes.

[0049] The turntable 200 has a positioning structure and a driving structure on its side. When the pushing structure 400 pushes the bamboo tube toward the bamboo splitting knife 201, the positioning structure of the turntable 200 fixes the turntable 200 relatively.

[0050] After the back end of the bamboo tube passes through the bamboo splitting knife 201, the positioning structure of the turntable 200 opens, the driving structure of the turntable 200 rotates the turntable 200 to a set angle, and the positioning structure of the turntable 200 then fixes the turntable 200 relatively.

[0051] The turntable 200 is driven to rotate by the turntable 200 drive structure on the side. At the same time, the turntable 200 positioning structure fixes the turntable 200 relatively, so that the bamboo splitting knife 201 is relatively fixed, preventing the bamboo splitting knife 201 from being unstable during impact, which would result in bamboo pieces of different sizes after splitting.

[0052] The rotating cylinder 300 is provided with a cylinder positioning structure and a cylinder driving structure on its side. When the bamboo clamping arm 500 pulls a single bamboo piece out of the rotating cylinder 300, the cylinder positioning structure fixes the rotating cylinder 300 relatively. After the bamboo clamping arm 500 pulls a single bamboo piece out of the rotating cylinder 300, the cylinder positioning structure opens and the cylinder driving structure drives the rotating cylinder 300 to rotate at a set angle.

[0053] In this way, the bamboo clamping arm 500 can continuously remove bamboo pieces from one angle. Each time a bamboo piece is removed, the rotating cylinder 300 rotates by one angle, and the bamboo clamping arm 500 removes a bamboo piece. This operation is repeated until the bamboo clamping arm 500 pulls all the bamboo pieces out of the rotating cylinder 300 for feeding. During the removal process, the cylinder positioning structure fixes the rotating cylinder 300, ensuring that the rotating cylinder 300 remains relatively fixed while the bamboo clamping arm 500 removes a single bamboo piece from the rotating cylinder 300.

[0054] The inner wall of the rotating cylinder 300 is provided with multiple horizontally arranged limiting strips 301. The multiple limiting strips 301 are arranged around the circumference of the rotating cylinder 300 at intervals. There are limiting strip grooves between adjacent limiting strips 301 for bamboo strips to pass through. The front end of the rotating cylinder 300 is provided with multiple spreading pieces 302. The inner ends of the multiple spreading pieces 302 are gathered together to form a fixed block. The fixed block is fixed at the center position of the front end of the rotating cylinder 300. The multiple spreading pieces 302 are arranged around the fixed block at intervals. Along the direction from the inside to the outside, the spreading pieces 302 are arranged to be inclined forward, and the spreading pieces 302 are arranged to be aligned with the limiting strip grooves.

[0055] After multiple bamboo strips enter the rotating cylinder 300, they are placed in the limiting grooves and move forward along the limiting grooves. When the front ends of the multiple bamboo strips extend from the front end of the rotating cylinder 300, multiple spreading pieces 302 are located in the area surrounded by the multiple bamboo strips. The outer ends of the spreading pieces 302 abut against the inner sidewall of the bamboo strips from the inside out, restricting the bamboo strips from bending inward, so that the multiple bamboo strips maintain an enclosed posture.

[0056] Thus, when the bamboo tube is cut into multiple bamboo strips, the multiple bamboo strips enter the rotating cylinder 300. However, as the multiple bamboo strips move forward in the bamboo tube, they will collapse towards the center, causing the positions of the multiple bamboo strips to become disordered. Therefore, the spreading plate 302 abuts against the inner wall of the bamboo strip. The multiple spreading plates 302 spread the multiple bamboo strips apart, and the multiple spread bamboo strips maintain an enclosed posture. The spreading plates 302 spread the bamboo strips to the designated position in the limiting groove to ensure that the bamboo clamping arm 500 can accurately clamp the bamboo strip.

[0057] The bamboo splitting knife 201 includes a fixing ring 203, which encloses a bamboo splitting area. Multiple cutting blades 202 are located in the bamboo splitting area. A central block 204 is provided at the center of the bamboo splitting area. The outer ends of the cutting blades 202 are connected to the fixing ring 203, and the inner ends of the cutting blades 202 are connected to the central block 204. Multiple cutting blades 202 are arranged around the central block 204 at intervals. The central block 204 has a rearward-facing splitting surface, which protrudes rearward and forms an annular blade 205 arranged around the center of the splitting surface.

[0058] As the bamboo tube passes through the bamboo splitting knife 201, multiple cutting blades 202 cut the outer wall of the bamboo tube, dividing it into multiple bamboo strips. The central block 204 is placed inside the bamboo tube, and the ring blade 205 cuts off the inner sections of the bamboo tube, so that the multiple bamboo strips are separated.

[0059] In this way, when the bamboo tube passes through the cutter, multiple cutting blades 202 cut the outer wall of the bamboo tube, dividing the bamboo tube into multiple bamboo pieces, while the annular blade 205 breaks the inner section of the bamboo tube, ensuring that the bamboo tube is divided into multiple bamboo pieces.

[0060] The center block 204 is located behind the fixing ring 203, and the cutting blade 202 is arranged at an angle to the rear along the direction from the outside to the inside.

[0061] In this way, as the bamboo tube passes through the bamboo splitting knife 201, the central block 204 will first break open the inner section of the bamboo tube, which is beneficial for the subsequent cutting knife 202 to divide the bamboo tube into multiple bamboo pieces.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
