Description

Technical Field

[0001] This invention belongs to the technical field of bamboo processing equipment, specifically a bamboo splitting machine with multi-blade telescopic adjustment and automatic centering function. Background Technology

[0002] Bamboo, as an important biomass resource, has wide applications in various fields such as construction, furniture manufacturing, and handicrafts. Due to the structural characteristics of bamboo, it often needs to be split into strips or sheets of a certain width for later use during processing. Traditional bamboo splitting is mainly done manually, which is not only inefficient but also labor-intensive and unsafe. With the increasing demand for industrialized production, automated mechanized bamboo splitting equipment has emerged, greatly improving production efficiency and processing quality.

[0003] In existing technology, bamboo splitting machines consist of a fixed cutter disc, a drive mechanism, and a feeding mechanism. Most traditional bamboo splitting machines use a fixed number of blades, typically 3, 4, 6, or 12. These blades are evenly distributed on a fixed cutter disc or fixed to the machine body in other ways. The drive mechanism includes components such as a motor and a reducer to provide sufficient power to rotate the cutter disc, thereby cutting the bamboo. The feeding mechanism generally has a dedicated worktable or clamp for placing the bamboo tubes to be processed, ensuring that only one bamboo tube is fed into the cutting area at a time. During operation, the appropriate blade configuration is selected according to the required bamboo specifications, and the height and angle of the feed inlet are adjusted to accommodate raw materials of different diameters. The bamboo is then fed to the operator's position in an orderly manner via the feeding mechanism. The operator manually places the prepared whole bamboo tube in the designated position, visually aligns it, and activates the drive mechanism to push the fixed cutter disc to split the bamboo.

[0004] Currently, bamboo splitting machines use a fixed cutter head or fixed blades. Changing the number of bamboo strips requires manual replacement of the cutter head or blade assembly, making the entire process very complicated and taking a long time to stop. Relying on manual visual alignment, the bamboo tubes are prone to eccentric breakage when cutting, resulting in uneven splitting, material waste, and reduced precision.

[0005] Therefore, the present invention provides a bamboo splitting machine with multi-blade telescopic adjustment and automatic centering function. Summary of the Invention

A shock-absorbing spring is sleeved on the outside of the centering cone and is located inside the support arm. The centering cone is used to align with the hollow part in the middle of the bamboo material.

[0014] Preferably, a second servo motor is fixedly connected to the side wall of the sensor base, and the output shaft of the second servo motor is fixedly connected to the infrared camera for controlling the rotation of the infrared camera.

[0015] Preferably, the bamboo splitting platform is provided with a pushing mechanism, which includes two sliding frames slidably connected to the side wall of the bamboo splitting platform.

This allows the blades to process bamboo of different specifications in a single operation, significantly improving production efficiency and reducing manual intervention without the need to change the blade disc. The automatic centering mechanism automatically calibrates the center of the bamboo before splitting, improving the uniformity and accuracy of bamboo splitting. It ensures the centering and fixing effect of the bamboo tip. Before splitting, the bamboo is guided to be as coaxial as possible with the blade support frame, ensuring uniform splitting.

A first servo motor is used to control the rotation angle of the cylinder, thereby controlling the angle of the blades and achieving flexibility in splitting bamboo. The blade disc has multiple grooves, and one end of the blade is inserted into the groove. The groove is located on the main axis of the blade disc, which ensures that the blade is always aligned with the main axis of the blade disc, guaranteeing the stability and accuracy of the cutting.

[0020] 3. The bamboo splitting machine of the present invention, which features multi-blade telescopic adjustment and automatic alignment, outputs corresponding blades through a cylinder to control the number of blades. A first servo motor controls the rotation angle of the cylinder, thereby controlling the angle of the blades and achieving flexibility in splitting bamboo.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 6As shown, the device includes a bamboo splitting platform 1; an automatic bamboo splitting mechanism 3 is provided on one side of the bamboo splitting platform 1, which provides the number and angle of blades required to split the bamboo material 5 based on measured data; the automatic bamboo splitting mechanism 3 includes a blade holder 6; the blade holder 6 is located on one side of the bamboo splitting platform 1, and multiple cylinders 8 are fixedly connected to the blade holder 6. The output ends of the cylinders 8 are all equipped with blades 11 via connecting shafts 9. A blade disc 10 is fixedly connected to the side wall of the blade holder 6 away from the bamboo splitting platform 1, and multiple grooves 23 are formed on the blade disc 10. One end of each blade 11 is inserted into a groove 23; the grooves 23 are all located on the main axis of the blade disc 10, and the blades 11 and the grooves 23 are fitted together; multiple first servo motors 7 are provided on the blade holder 6, and the output shafts of the first servo motors 7 are fixedly connected to the outer wall of the cylinders 8, used to control the cutting angle of the blades 11; there are nine cylinders 8, which are evenly arranged in a three-part distribution.

[0031] The automatic bamboo splitting mechanism 3 provided by this invention, in use, is fed by a feeding machine to bamboo material 5 onto the splitting table 1, and then pushed to the automatic bamboo splitting mechanism 3. Before splitting, the bamboo material 5 needs to be measured. The size of the bamboo material 5 is measured by an automatic measuring mechanism 4, and the measurement result is transmitted to the system. The system estimates the diameter and thickness of the bamboo material 5, and then quickly calculates the required number and angle of blades 11 based on the diameter and thickness of the bamboo material 5. When equipping the blades 11, the principle of three-part, six-part, and twelve-part blade modes is followed. When the diameter of the bamboo material 5 is less than the set value d, the first cylinder 8 in each of the three divisions will be opened, and the corresponding blade 11 will be output through the cylinder 8, realizing the three-part blade mode. When the diameter of the bamboo material 5 is greater than the set value D, each of the three divisions of cylinder 8 will be opened, and the corresponding blade 11 will be output through the cylinder 8, realizing the twelve-part blade mode. When the diameter of the bamboo material 5 is between d and D, the first two cylinders 8 in each of the three divisions will be opened. The cylinder 8 outputs the corresponding blade 11, enabling the activation of the six-blade mode and thus controlling the number of blades 11. This facilitates the cutting of bamboo 5 into uniformly wide sheets. When the angle of the blade 11 needs to be adjusted, the first servo motor 7 is activated, which drives the cylinder 8 to rotate. The cylinder 8, through the connecting shaft 9, drives the blade 11 to rotate, thereby controlling the angle of the blade 11. This allows for cutting bamboo 5 of different thicknesses, achieving flexibility in bamboo splitting. The cutter disc 10 has multiple grooves 23. One end of the blade 11 is inserted into the groove 23, and the groove 23 is located on the main axis of the cutter disc 10. This ensures that the blade 11 is always aligned with the main axis of the cutter disc 10, guaranteeing the stability and accuracy of the cutting. By controlling the automatic bamboo splitting mechanism 3, the number of bamboo splitting blades can be quickly switched, allowing the blades to process bamboo of different specifications in one operation. This significantly improves production efficiency and reduces manual intervention, eliminating the need to change the cutter disc 10.

[0032] like Figure 1As shown, the top of the bamboo splitting platform 1 is fixed with multiple M-shaped bamboo support pieces, and the bamboo material 5 is placed on the M-shaped bamboo support pieces.

[0033] The M-shaped bamboo support strip provided by this invention, when in use, adopts an "M"-shaped geometric structure with a symmetrical sawtooth-shaped protrusion in its cross-section, forming multiple independent support points; it is preferably made of high-strength alloy steel or wear-resistant nylon material, taking into account both rigidity and elastic buffering capacity; and it is arranged in a linear array along the top of the bamboo splitting platform 1, with the spacing between adjacent strips controlled within the range of 50-100mm, ensuring full coverage of the bamboo material and avoiding local suspension; it is locked in the T-shaped groove pre-set on the surface of the bamboo splitting platform by bolts, which facilitates quick disassembly and adjustment; when the bamboo material 5 is pushed to the processing position, the M-shaped bamboo support strip absorbs the slight fluctuations caused by the diameter difference of the bamboo material by its own elastic deformation, achieving self-adaptive fitting.

[0034] like Figure 2 As shown, the blade holder 6 is provided with a centering mechanism 12 on the side away from the bamboo splitting platform 1. The centering mechanism 12 is located at the center of the blade disc 10 via the main shaft of the blade disc 10. The main shaft of the blade disc 10 ensures that the bamboo material 5 and the blade disc 10 are always coaxial.

[0035] The centering mechanism 12 provided by this invention is fixed inside the cutter head 10 by a support frame during use. The centering mechanism 12 can ensure the centering and fixing effect of the front end of the bamboo material 5; guide the bamboo material 5 to be as coaxial as possible with the cutter head 6 before slicing, ensure uniform slicing, realize the symmetrical cutting of bamboo by multiple cutter heads 10 and the circumferential layer-by-layer cutting, so that the bamboo is subjected to uniform force during the cutting process, avoids bamboo cracking, ensures the quality of the radial fracture of bamboo, and reduces the waste of bamboo material 5 in the harvesting and processing process.

[0036] like Figure 2 As shown, the centering mechanism 12 includes a centering cone 15 and multiple support arms 17. One end of the centering cone 15 is fixed to the main shaft of the cutter head 10. The support arms 17 are located on the outside of the centering cone 15, with one end close to the centering cone 15 slidably connected to the outside of the centering cone 15 and the other end away from the centering cone 15 fixed to the outer wall of the centering cone 15. A shock-absorbing spring 16 is sleeved on the outside of the centering cone 15 and is located inside the support arm 17. The centering cone 15 is used to align with the hollow part in the middle of the bamboo material 5.

[0037] When the centering mechanism 12 provided by the present invention is in use, after the blade 11 is stabilized, the rear push plate continues to move forward under the drive of the lower drive motor 20, pushing the bamboo material 5 toward the blade 11 for cutting. During the cutting process, the centering cone 15 of the centering mechanism 12 is aligned with the middle of the bamboo material 5 and penetrates it. Under the action of the shock-absorbing spring 16, the six support arms 17 keep the bamboo material 5 stable in the center. When the push plate reaches the limit position and approaches the cutter head 10, the bamboo material 5 passes through the blade 11, and the remaining length will automatically split due to tension. The process of splitting a bamboo material 5 is completed. The push plate does not need to be in complete contact with the centering mechanism 12. The bamboo splitting table 1 and the bamboo splitting knife only need to work according to the predetermined process and do not interfere with each other.

[0038] like Figure 2 and Figure 3 As shown, three initial blades are fixed between the spindle of the cutter head 10 and the support ring, and the support ring between two of the initial blades contains three grooves 23.

[0039] In use, the blade disc 10 provided by this invention has cylinders 8 arranged in three equal parts around the blade holder 6, with three cylinders 8 in each part. This arrangement allows the blades to act more evenly on the bamboo material 5 during operation, improving the bamboo splitting effect. Simultaneously, three initial blades are fixed between the main shaft of the blade disc 10 and the support ring. The support ring between two of the initial blades contains three grooves 23. This design increases the number and distribution density of the blades, further improving the efficiency and quality of bamboo splitting.

[0040] like Figure 2 and Figure 3 As shown, the outer wall of the main shaft of the cutter head 10 is provided with tooth grooves 13, and the end of the blade 11 away from the cylinder 8 is provided with saw teeth 14. The saw teeth 14 mesh with the corresponding tooth grooves 13 to stabilize the cutter.

[0041] When the tooth groove 13 and saw teeth 14 provided by the present invention are in use, the saw teeth 14 below the cutter head 10 and the tooth groove 13 on the central shaft of the cutter head 10 are connected by meshing in a self-locking slot connection. After the cylinder 8 adjusts the angle, the blade 11 passes through the depth of the groove 23 and finally connects and fixes with the tooth groove 13 in the center of the cutter head 10, which can ensure unidirectional locking during the cutting process.

[0042] like Figure 1 and Figure 6 As shown, the bamboo splitting table 1 is provided with an automatic measuring mechanism 4 at one end near the knife holder 6, which is used to measure the outer diameter and wall thickness of the bamboo material 5. The automatic measuring mechanism 4 includes a sensor base 19, which is fixed at the end of the bamboo splitting table 1 near the knife holder 6. An infrared camera 18 is rotatably connected to the sensor base 19 via a rotating shaft.

[0043] When the automatic measuring mechanism 4 provided by the present invention is in use, an infrared camera 18 is provided below the bamboo material 5 to detect the diameter and thickness of the bamboo tube and transmit the measurement results to the system. The system estimates the diameter and thickness of the bamboo material 5 and then quickly calculates the required number and angle of the blades 11 based on the diameter and thickness of the bamboo material 5.

[0044] like Figure 5 As shown, a second servo motor 22 is fixedly connected to the side wall of the sensor base 19. The output shaft of the second servo motor 22 is fixedly connected to the infrared camera 18 and is used to control the rotation of the infrared camera 18.

[0045] When the second servo motor 22 provided by the present invention is used, the output shaft of the second servo motor 22 drives the infrared camera 18 to rotate, thereby expanding the shooting range of the infrared camera 18 and improving the applicability of the infrared camera 18.

[0046] like Figure 1 As shown, the bamboo splitting platform 1 is equipped with a pushing mechanism 2. The pushing mechanism 2 includes two sliding frames slidably connected to the side wall of the bamboo splitting platform 1. A push plate is fixed between the two sliding frames. Two sprockets 21 are rotatably connected to the bottom of the bamboo splitting platform 1 via a rotating shaft. A chain is sleeved between the two sprockets 21. A second rotating wheel is fixedly connected to one end of one of the rotating shafts. A drive motor 20 is provided below the bamboo splitting platform 1. A first rotating wheel is fixedly connected to the output shaft of the drive motor 20. A belt is sleeved between the first rotating wheel and the second rotating wheel. A connecting rod is provided between the chain and the sliding frame.

[0047] When in use, the pushing mechanism 2 provided by the present invention drives the first rotating wheel by turning on the electric drive motor 20, which in turn drives the belt to rotate, which in turn drives the second rotating wheel to rotate, which in turn drives the shaft to rotate, which in turn drives the connected sprocket 21 to rotate, which in turn drives the chain to rotate, which in turn drives another sprocket 21 to rotate, thereby achieving continuous rotation of the chain. The chain drives the connecting plate to move, which in turn drives the sliding frame to move, which in turn drives the push plate to move, thereby pushing the bamboo material 5.

[0048] like Figure 4 As shown, the width of the blade 11 is ≤35mm, and the length of the blade 11 is 1-8mm shorter than the distance between the lower surface of the base of the tool holder 6 and the upper surface of the top seat of the tool holder 6. The material of the blade 11 can be selected from one of high-hardness tungsten carbide, TiN coating or ceramic composite blade 11.

[0049] The blade 11 provided by this invention is used for cutting bamboo 5. The blade 11 is designed as an irregularly shaped blade, with a width not exceeding 35mm and a length 1-8mm shorter than the distance between the lower surface of the base of the tool holder 6 and the upper surface of the top seat of the tool holder 6. This size design ensures that the blade 11 has sufficient cutting area while avoiding interference with other components due to excessive length. The material of the blade 11 can be selected from high-hardness tungsten carbide, TiN coating, or ceramic composite blades 11. These materials have high hardness and wear resistance, meeting the requirements of long-term, high-intensity bamboo-splitting work.

[0050] Working principle: The bamboo material 5 is conveyed to the bamboo splitting table 1 by the feeding machine. The M-shaped support plate can position the bamboo material 5 in the center of the mechanism. Then, the bamboo material 5 is pushed to the front of the automatic bamboo splitting mechanism 3 by the pushing mechanism 2. Under the measurement of the automatic measuring mechanism 4, the size of the bamboo material 5 is calculated. Then, the automatic bamboo splitting mechanism 3 is controlled to select the appropriate number of blades 11 and determine the splitting angle to split the bamboo material 5 into a suitable bamboo strip shape. By controlling the automatic bamboo splitting mechanism 3, the number of bamboo splitting blades can be quickly switched, allowing the blades to process bamboo of different specifications in one operation, significantly improving production efficiency and reducing manual intervention, without the need to replace the blade disc 10; the automatic centering mechanism 12 can automatically calibrate the center of the bamboo material 5 before splitting, improving the uniformity and accuracy of bamboo splitting; it can ensure the centering and fixing effect of the front end of the bamboo material 5; it guides the bamboo material 5 to be as coaxial as possible with the support frame of the blade 11 before splitting, ensuring uniform splitting, realizing symmetrical cutting of bamboo by multiple blade discs 10, cutting the bamboo layer by layer along the circumference, so that the bamboo is subjected to uniform force during the cutting process, avoiding bamboo cracking, ensuring the quality of the radial fracture of the bamboo, and reducing the waste of bamboo material 5 in the harvesting and processing process.

[0051] The system detects the diameter and thickness of the bamboo tube using an automatic measuring mechanism 4. It can quickly and automatically calculate the required number and angle of blades. The cylinder 8 is used to output the corresponding blades 11 and control the number of blades 11. The first servo motor 7 is used to control the rotation angle of the cylinder 8, thereby controlling the angle of the blades 11 and achieving flexibility in splitting bamboo. The blade disc 10 has multiple grooves 23. One end of the blade 11 is inserted into the groove 23, and the groove 23 is located on the main axis of the blade disc 10. This ensures that the blade 11 is always aligned with the main axis of the blade disc 10, guaranteeing the stability and accuracy of the cutting.

The cylinder 8 outputs the corresponding blades 11 and controls the number of blades 11. The first servo motor 7 controls the rotation angle of the cylinder 8, thereby controlling the angle of the blades 11 and achieving flexibility in splitting bamboo.

The serrations 14 below the blade disc 10 and the tooth grooves 13 on the central axis of the blade disc 10 are connected by a self-locking slot through meshing. After the cylinder 8 adjusts the angle, the moving blade passes deep into the groove 23 of the blade disc 10 and finally connects and is fixed with the tooth groove 13 in the center of the blade disc 10, ensuring unidirectional locking during the cutting process.

[0053] By activating the drive motor, the output shaft of the drive motor 20 drives the first rotating wheel, which in turn drives the belt to rotate. The belt then drives the second rotating wheel to rotate, which in turn drives the shaft to rotate. This rotation drives the connected sprocket 21 to rotate, which in turn drives the chain to rotate. The chain then drives another sprocket 21 to rotate, thus achieving continuous rotation of the chain. The chain drives the connecting plate to move, which in turn drives the sliding frame to move, which in turn drives the push plate to move, thereby pushing the bamboo material 5.
