Description

Technical Field

[0001] This utility model relates to the field of bamboo processing machinery technology, and in particular to a rotating device for removing inner nodes and splitting bamboo. Background Technology

[0002] Bamboo, as an important natural engineering material, is widely used in building decoration, furniture manufacturing, and handicrafts due to its excellent mechanical properties and environmentally friendly characteristics. In the industrial processing of bamboo, the bamboo tubes formed after cutting raw bamboo require a crucial process of removing the inner nodes. Traditional manual node removal suffers from three major technical bottlenecks: First, it is difficult to balance work efficiency and processing quality, requiring operators to repeatedly adjust the angle of the bamboo tube and use different sized chisels, resulting in long processing times per piece; second, controlling processing precision is difficult, as manual operation easily causes excessive cutting or penetrating damage to the inner wall of the bamboo tube, leading to a high scrap rate; and third, there are serious safety hazards, as high-speed impact chisels can easily rebound and cause injuries.

[0003] While existing mechanized equipment has improved processing efficiency to some extent, it still has significant drawbacks: fixed tool systems cannot adapt to changes in the diameter of bamboo tubes of different specifications, leading to bamboo node residue; single-axis rotating drilling mechanisms are ineffective at handling the connection between bamboo nodes and the tube wall, requiring subsequent manual adjustments; traditional pushing mechanisms lack precise positioning capabilities, easily resulting in cumulative errors during continuous operation. More significantly, the tool systems of existing equipment generally employ an integral structure, which is highly susceptible to tool chipping or motor overload when encountering exceptionally hard bamboo nodes, severely impacting production continuity. Furthermore, the limiting mechanisms of traditional devices often use simple clamping methods, frequently resulting in axial movement of the bamboo tube under high-speed rotation, causing spiral cutting marks on the processed surface and affecting the quality of the finished product. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a rotating bamboo splitting device that can split bamboo and remove internal knots during the splitting process, thereby reducing the scrap rate.

[0007] Furthermore, the limiting component includes a first telescopic cylinder, and the left and right vertical plates of the limiting frame are provided with strip-shaped sliding openings. A first mounting plate is provided at the lower end of the limiting frame. The left and right ends of the first mounting plate are connected and fixed by second bolts passing through the strip-shaped sliding openings. Multiple first arc-shaped grooves are provided at equal intervals on the upper surface of the first mounting plate. The first telescopic cylinder is embedded in the middle of the upper horizontal plate of the limiting frame. A pressing limiting plate is provided at the end of the telescopic rod of the first telescopic cylinder. Multiple second arc-shaped grooves that cooperate with the first arc-shaped grooves are provided at equal intervals on the lower surface of the pressing limiting plate.

[0008] Furthermore, the connector includes an extension block, and extension blocks are provided on both the left and right sides of the support ring. The extension blocks are fixed inside the cut opening by a third bolt.

[0009] Furthermore, the pushing component includes a movable plate, and the support base has a second strip-shaped groove on both its left and right sides. A synchronous motor is installed in the second strip-shaped groove, and the output end of the synchronous motor is connected to a second screw. A sliding block is spirally sleeved on the second screw, and the sliding block is connected to a U-shaped movable seat. The U-shaped movable seat is sleeved on the front end of the support base. The lower surface of the horizontal plate of the U-shaped movable seat has guide rail grooves on both its left and right ends that cooperate with the guide rail. The movable plate is installed on the upper surface of the horizontal plate of the U-shaped movable seat. A second telescopic cylinder is embedded in the center of the front of the movable plate.

[0010] The beneficial effects of this utility model are as follows: This utility model achieves precise positioning and continuous processing of bamboo tubes by setting multiple sets of adjustable bamboo splitting parts in the support frame in conjunction with the limiting frame and the pushing mechanism. The modular tool system composed of the support ring and the blade mounting plate can quickly adjust the cutting parameters.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please see Figures 1 to 4As shown, this utility model provides an embodiment: a rotating bamboo splitting device for removing inner nodes, including a support base 1. Guide rails 11 are provided at both ends of the upper surface of the support base 1. A limiting frame 2 is provided at the rear end of the upper surface of the support base 1. A limiting component 3 for limiting the bamboo tube is provided inside the limiting frame 2. A support frame 4 is connected to the middle of the rear surface of the left and right vertical plates of the limiting frame 2 via a connecting rod 21. Multiple bamboo splitting components 6 are installed at equal intervals inside the support frame 4. A pushing component 7 for pushing and setting up the bamboo tube is provided at the front end of the upper surface of the support base 1. Each bamboo splitting component 6 includes a blade holder 61. A limiting block 62 is provided on the upper surface of the blade holder 61. Multiple limiting grooves 63 that cooperate with the limiting block 62 are opened at equal intervals on the rear surface of the upper horizontal plate of the support frame 4. A cutting opening 64 is opened in the middle of the blade holder 61. The cutting opening 64 is... Connector 8 is connected to support ring 65. Support rod 66 is provided in the middle of support ring 65. Multiple blade mounting plates 67 are provided at equal intervals on the outer side of support rod 66. Blade mounting plates 67 are located between support rod 66 and support ring 65. Blade mounting plates 67 have strip-shaped blade mounting grooves 68. A first motor (not shown) is embedded in the middle of the front of support rod 66. The output shaft of the first motor is connected to a rotating disk 69. A first strip-shaped groove 9 is provided in the middle of rotating disk 69. A second motor (not shown) is provided in the first strip-shaped groove 9. The output end of the second motor is connected to a first screw (not shown). Moving blocks 92 are spirally sleeved on both the left and right ends of the first screw. Connecting blocks 93 are connected to the front of moving blocks 92 by fixing screws. Drill bits 94 are provided on the front of connecting blocks 93.

[0017] The support base is the basic structure that supports the entire device, and can be implemented using a welded steel plate frame. Guide rails on its surface provide sliding tracks for the moving parts. The limiting frame is the constraint mechanism that fixes the bamboo tubes, and can be formed by welding rectangular steel pipes. Internal limiting components use a cylinder to drive a pressing plate to fix the bamboo tubes. The bamboo-splitting component is the core component that performs the cutting operation, and can be a split-type tool holder structure. A ring-shaped cutting area is formed by a support ring and a support rod. The blade mounting slot is the positioning structure that fixes the cutting tool, and can be a T-slot design that allows the blade to be adjusted radially. The first strip-shaped groove is the spatial structure that accommodates the driving components, and can be formed by milling. An internal telescopic protective sleeve prevents chips from entering.

[0018] Specifically, during processing, after the bamboo tube is positioned by the arc-shaped groove within the limiting frame, the pushing mechanism moves the bamboo tube towards the bamboo-splitting component. The blade assembly within the support ring rotates and cuts under motor drive, while a rotating disk drives a bidirectional screw to make the drill bit move synchronously towards the center. When encountering exceptionally hard bamboo nodes, the strip structure of the blade mounting groove allows for slight displacement of the blade, preventing damage to the tool from rigid impacts. The mating structure of the guide rail and the moving seat ensures no skewing occurs during the pushing process, and the fitting design of the limiting block and the limiting groove maintains the stable working state of the bamboo-splitting component.

[0019] Compared to existing technologies, traditional single-axis cutters can only perform cutting in one direction, while this solution achieves a three-dimensional cutting path through a ring-shaped arrangement of multi-directional inserts. In existing technologies, integral cutters are prone to breakage when encountering hard bamboo joints; this solution's split-type tool holder structure, through a combination of support rods and support rings, allows for individual replacement of components while maintaining structural strength. Traditional pushing mechanisms lack dynamic compensation capabilities; this solution's guide rail groove and moving seat cooperation structure can correct pushing trajectory deviations in real time.

[0020] Through the above technical solutions, this application effectively solves the problem of incomplete removal of inner nodes from bamboo tubes, and adapts to the processing needs of bamboo of different diameters through an adjustable tool system. The modular blade mounting structure reduces maintenance costs, and the bidirectional drive mechanism ensures a balanced distribution of cutting force. The protective sleeve design extends the service life of key components, and the combined application of multi-directional limiting mechanisms significantly improves the safety of the processing.

[0021] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the left half of the first screw has a left-hand thread, the right half of the first screw has a right-hand thread, the limiting block 62 is fixed in the limiting groove 63 by the first bolt, and a telescopic protective sleeve 91 is provided in the first strip groove.

[0022] Among them, left-hand and right-hand threads refer to the screw surface having a helical structure with opposite directions. This can be achieved using a double-ended anti-directional thread machining process. The symmetrically distributed thread structure enables the two moving blocks to move synchronously in opposite directions during screw rotation. The limiting block is fixed by the first bolt, meaning the tool holder and support frame are fastened using a detachable mechanical fastening method. This can be achieved using standard hexagonal bolts with anti-loosening washers, facilitating quick disassembly and maintenance of the tool assembly. The telescopic protective sleeve is a sealing device with axial extension. It can be achieved using corrugated tubular rubber material combined with a metal skeleton structure, covering the opening of the first strip-shaped groove to form a dynamic seal.

[0023] Specifically, when the first motor drives the rotating disk to rotate, the opposing thread structure of the first screw causes the two moving blocks to achieve symmetrical displacement within the first strip-shaped groove, driving the drill bit connected to the connecting block to form a symmetrical reaming trajectory. The limiting block uses a first bolt passing through the limiting groove to position and fix the tool holder within the support frame; when the tool needs to be replaced, the position can be adjusted by loosening the bolt. The telescopic protective sleeve deforms accordingly with the reciprocating motion of the moving blocks, always covering the working area of ​​the first strip-shaped groove, preventing bamboo chips from entering the transmission mechanism.

[0024] Compared to existing technologies, traditional bamboo-splitting devices often use a single-sided thread structure on the screw, leading to asynchronous tool movement. This solution achieves bidirectional symmetrical feed through an anti-directional thread design, ensuring symmetrical bamboo cutting. Conventional equipment typically uses welding or riveting to fix the tools; this solution uses bolt fixing, improving tool maintenance efficiency by more than three times. In existing technologies, the transmission groove is generally exposed; this solution's added telescopic protective sleeve effectively solves the problem of debris jamming.

[0025] Through the above technical solution, this application achieves precise symmetrical control of the tool movement trajectory, reduces the workload of equipment maintenance, avoids downtime caused by foreign object intrusion in the transmission mechanism, and significantly improves the stability of the bamboo joint cutting process and the maintainability of the equipment.

[0026] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the limiting member 3 includes a first telescopic cylinder 31, and the left and right vertical plates of the limiting frame 2 are provided with strip-shaped sliding openings 32. The lower end of the limiting frame 2 is provided with a first mounting plate 33. The left and right ends of the first mounting plate 33 are connected and fixed by second bolts 34 passing through the strip-shaped sliding openings 32. The upper surface of the first mounting plate 33 is provided with a plurality of first arc-shaped grooves 35 at equal intervals. The middle of the upper horizontal plate of the limiting frame 2 is provided with the first telescopic cylinder 31. The end of the telescopic rod of the first telescopic cylinder 31 is provided with a pressing limiting plate 36. The lower surface of the pressing limiting plate 36 is provided with a plurality of second arc-shaped grooves 37 that cooperate with the first arc-shaped grooves 35 at equal intervals.

[0027] The strip-shaped groove refers to a guide channel extending longitudinally along the vertical plate of the limiting frame. It can be achieved through laser cutting or milling and is used to constrain the lateral movement trajectory of the first support plate. The first arc-shaped groove is a supporting structure with a specific curvature, which can be machined using a CNC machine tool. Its curvature matches the outer diameter of the bamboo tube to achieve multi-point contact support. The second arc-shaped groove is a complementary groove structure located at the bottom of the pressing limiting plate. It can be manufactured through casting or stamping processes and forms a closed clamping space with the first arc-shaped groove. The first telescopic cylinder is a pneumatic actuator with linear output power, such as a double-acting cylinder structure, used to drive the pressing limiting plate to complete vertical lifting and lowering movements.

[0028] Specifically, the first mounting plate achieves lateral position adjustment through the cooperation of the second bolt and the strip-shaped sliding opening, allowing the spacing of the first arc-shaped grooves to adapt to bamboo tubes of different diameters. When the bamboo tube is placed in the first arc-shaped groove, the first telescopic cylinder drives the pressing and limiting plate downwards, causing the second arc-shaped groove to form a ring-like clamping action with the first arc-shaped groove. This clamping method, through the cooperation of two sets of complementary grooves, forms a continuous contact surface along the axial direction of the bamboo tube, while simultaneously utilizing multi-point contact to disperse clamping stress.

[0029] Compared to existing technologies, traditional limiting mechanisms use flat clamps to directly press against the outer wall of the bamboo tube, which can easily cause localized stress concentration and lead to deformation. This solution uses the cooperation of upper and lower arc-shaped grooves to form a contour-following clamp, maintaining sufficient clamping force while avoiding damage to the surface of the bamboo tube. The combination of the strip-shaped sliding opening and the second bolt gives the first mounting plate a lateral adjustment function, which can adapt to the processing needs of bamboo materials of different specifications.

[0030] Through the above technical solution, this application effectively solves the problem of spiral marks on the processed surface caused by the axial movement of the bamboo tube. The closed clamping structure formed by the upper and lower arc-shaped grooves can eliminate the relative sliding between the bamboo tube and the limiting component, and the constant clamping force provided by the first telescopic cylinder ensures the axial stability of the bamboo tube during processing. The strip-shaped sliding adjustment mechanism enables the equipment to quickly adapt to the processing needs of bamboo tubes of different diameters, avoiding the problem of bamboo node residue caused by the specification limitations of traditional equipment.

[0031] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the connector 8 includes an extension block 81. The support ring 65 has extension blocks 81 extending outward on both its left and right sides. The extension blocks 81 are connected and fixed in the cut opening 64 by a third bolt 82.

[0032] The extension block refers to the protruding structure extending outward from both sides of the support ring. It can be made of the same metal as the support ring through welding or integral molding, and is used to increase the contact area with the cutting edge of the tool holder. The third bolt is a threaded fastener, specifically a standard hexagonal bolt with a nut, used to detachably fix the extension block to the cutting edge of the tool holder. The extension block and the third bolt together form a modular connection structure. Under abnormal loads, the support ring and tool holder can be quickly separated by loosening the bolts, preventing damage to the overall structure.

[0033] Specifically, after the support ring is inserted into the cutting opening of the tool holder via extension blocks on both sides, a third bolt passes through the threaded hole in the extension block and the side wall of the tool holder to complete the fastening. When the tool system needs maintenance or replacement, the support ring can be removed entirely by simply loosening the third bolt, without disassembling the main structure of the tool holder. This connection method allows the support ring and the tool holder to form a rigid connection while maintaining separability. If tool jamming or abnormal vibration occurs during bamboo joint processing, the connection can be buffered and protected by adjusting the bolt preload.

[0034] Compared with existing technologies, traditional tool systems use integral casting or welding to fix the support ring to the tool holder, requiring the entire component to be replaced when the tool is damaged. In contrast, this solution uses a modular connection structure to enable rapid disassembly and assembly of key components, significantly reducing maintenance time. In existing technologies, integral structures are prone to stress concentration and tool holder cracking when encountering hard bamboo joints. This solution uses extension blocks to distribute the load and combines bolt fastening to form elastic constraints, effectively improving structural reliability.

[0035] Through the above technical solution, this application solves the maintenance difficulties caused by the overall structure of traditional tool systems, realizes the rapid replacement of the support ring assembly, and reduces equipment downtime; at the same time, the modular connection method can adapt to the installation requirements of different specifications of tools, and improves the equipment's adaptability to processing bamboo tubes of different diameters.

[0036] Please continue reading. Figure 1 and Figure 2As shown, in one embodiment of this utility model, the pushing member 7 includes a movable plate 71. The support base 1 has a second strip-shaped groove 72 on both its left and right sides. A synchronous motor (not shown) is installed in the second strip-shaped groove 72. The output end of the synchronous motor is connected to a second screw (not shown). A sliding block (not shown) is spirally sleeved on the second screw. The sliding block is connected to a U-shaped movable seat 73. The U-shaped movable seat 73 is sleeved on the front end of the support base 1. The lower surface of the horizontal plate of the U-shaped movable seat 73 has guide rail grooves (not shown) that cooperate with the guide rail 11 at both ends. The movable plate 71 is installed on the upper surface of the horizontal plate of the U-shaped movable seat 73. A second telescopic cylinder 74 is embedded in the center of the front of the movable plate 71. An L-shaped support plate 75 is installed at the end of the telescopic rod of the second telescopic cylinder 74. The L-shaped support plate 75 is located on the rear side of the movable plate 71. A plurality of third arc-shaped grooves 76 are equally spaced on the upper surface of the horizontal plate of the L-shaped support plate 75.

[0037] The second groove refers to the linear guide structure on the side of the support base, which can be a rectangular groove machined by machining. Its function is to provide installation space for the second screw and limit its movement trajectory. The synchronous motor is the power device that drives the rotation of the second screw, which can be a servo motor with a reducer. Its function is to achieve the positioning accuracy of the pushing mechanism by precisely controlling the rotational speed. The second screw is a threaded transmission rod, which can be machined from a trapezoidal threaded steel rod. Its function is to convert the rotational motion of the motor into the linear displacement of the sliding block. The guide rail groove is the groove structure at the bottom of the U-shaped moving seat that mates with the guide rail. It can be formed by embedding wear-resistant nylon material. Its function is to reduce frictional resistance and maintain movement stability through sliding contact. The third arc-shaped groove is a semi-circular positioning structure on the surface of the L-shaped support plate, which can be CNC milled. Its function is to achieve multi-point fixation through contact with the curved surface of the bamboo tube's outer wall.

[0038] Specifically, when the synchronous motor starts, the second screw drives the sliding block to move axially along the second strip groove, pushing the U-shaped moving seat to slide smoothly along the guide rail of the support base through the guide rail groove. After the moving plate moves synchronously to the set position with the U-shaped moving seat, the second telescopic cylinder drives the L-shaped support plate to extend backward, so that the third arc-shaped groove forms multi-point contact with the outer wall of the bamboo tube. During the pushing process, the cooperation between the guide rail groove and the guide rail constrains the movement direction of the U-shaped moving seat, and the closed-loop control of the synchronous motor eliminates the gap error existing in traditional mechanical transmission.

[0039] Compared to existing technologies, traditional pushing mechanisms use a single power source to drive the push rod structure, and the lack of a displacement feedback mechanism results in a cumulative error exceeding 3 mm. This solution, through a precision transmission combination of a synchronous motor and a second screw, combined with the guiding and limiting function of the guide rail groove, controls the bamboo tube pushing and positioning accuracy within 0.5 mm. Furthermore, multiple third arc-shaped grooves on the L-shaped mounting plate form distributed support points, effectively preventing the bamboo tube from deflecting during the pushing process compared to the line contact method of traditional V-shaped clamps.

[0040] Through the above technical solution, this application solves the problem of cumulative error caused by the lack of precise positioning function in traditional pushing mechanisms, and achieves precise positioning of bamboo tubes during continuous processing. The distributed support design with multiple arc-shaped grooves enhances the stability of the bamboo tubes and prevents axial movement during processing. The synchronous motor-driven screw transmission mechanism improves the controllability of the pushing action, enabling the equipment to adapt to the processing needs of bamboo tubes of different lengths.

[0041] In this utility model, the synchronous motor, the telescopic cylinder, and the motor are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0042] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
