Description

Technical Field

[0001] This application relates to the field of wood processing technology, and more specifically, to an improved edge sawing machine for wood panels. Background Technology

[0002] Traditional wood panel sawing machines suffer from insufficient positioning accuracy and low cutting efficiency during processing. Existing equipment mostly uses a fixed worktable, requiring manual adjustment of the wood panel's position for multi-angle cutting, which is not only cumbersome but also prone to cutting errors due to positioning deviations. While some machines are equipped with clamping devices, they lack simultaneous rotational operation; the panel must be released to adjust it before re-clamping it to continue cutting, making it difficult to achieve continuous cutting of complex contours. To address these issues, there is an urgent need to develop an improved sawing machine with rotary positioning and bidirectional synchronous cutting capabilities to improve processing accuracy and efficiency. Utility Model Content

[0003] This application provides an improved wood panel sawing machine, including a mounting platform, a rotating assembly, a pressing assembly, and a cutting assembly. The mounting platform has a boss and a bracket. The boss is disc-shaped. The rotating assembly includes a rotary motor and a rotating table. The rotary motor is fixedly mounted on the lower surface of the mounting platform, and its output shaft passes through the central axis of the boss. The rotating table is fixed to the free end of the rotary motor's output shaft, and its lower surface has a groove corresponding to the boss, into which the boss extends. The pressing assembly includes a telescopic cylinder and a pressing structure. The telescopic cylinder is on the bracket and coaxial with the rotary motor. The pressing structure is rotatably mounted on the output shaft of the telescopic cylinder and is used to press the wood panel firmly onto the rotating table. The cutting assembly includes a slide rail, a cutting motor, and a cutting disc. The cutting motor is mounted on the slide rail, and the cutting disc is fixed to the free end of the cutting motor's output shaft, which is freely extendable and retractable. Two sets of the cutting assemblies are fixed to the mounting platform and are symmetrical about the center of the rotating table.

[0004] In some embodiments, the clamping assembly includes a mounting plate, a clamping plate, a connecting rod, and a spring. The center of the mounting plate is rotatably mounted on the output shaft of the telescopic cylinder. The clamping plate is parallel to the mounting plate. One end of the connecting rod is fixed to the upper surface of the clamping plate, and the other end of the connecting rod passes through the mounting plate and is slidable. The spring is disposed between the mounting plate and the clamping plate.

[0005] In some embodiments, the working surfaces of the clamping plate and / or the rotary table are provided with anti-slip rubber or protrusions.

[0006] In some embodiments, a collection hopper arranged along the cutting direction is provided below the mounting platform, the collection hopper extends to the outside of the mounting platform, and a support is provided below the collection hopper.

[0007] In some embodiments, the slide rail surface is provided with a nano-ceramic coating, and the slide rail adopts a conical structure to prevent sawdust from being trapped and affecting sliding.

[0008] In some embodiments, electrostatic adsorption devices are integrated on both sides of the slide rail for capturing suspended wood chip particles.

[0009] In some embodiments, the sawing machine further includes a laser positioner mounted on the bracket via a mounting rod marked with graduations, the laser positioner being used to assist in positioning the wooden board on the turntable.

[0010] The sawing machine of this application achieves continuous rotary cutting of wood boards at any angle with an accuracy of ±0.5° through the design of a rotary motor and a rotating component that cooperates with the boss and groove. At the same time, combined with the clamping component, it can clamp the wood boards while rotating, solving the process defects of repeated clamping and adjustment in traditional equipment. The bidirectional symmetrically arranged cutting components can complete the sawing operation on both sides simultaneously, improving cutting efficiency, and the bidirectional balanced cutting force eliminates the problem of wood board displacement caused by unilateral cutting.

[0018] Please see Figure 1 This application provides an improved wood panel sawing machine 100, including a mounting platform 10, a rotating assembly 20, a pressing assembly 30, and a cutting assembly 40. The mounting platform 10 has a boss 11 and a support 12. The boss 11 is disc-shaped. The rotating assembly 20 includes a rotary motor 21 and a rotating table 22. The rotary motor 21 is fixedly mounted on the lower surface of the center of the mounting platform 10, and its output shaft passes through the central axis of the boss 11. The rotating table 22 is fixed to the free end of the output shaft of the rotary motor 21. The lower surface of the rotating table 22 has a groove 221 corresponding to the boss 11, and the boss 11 extends into the groove 221. The pressing assembly 30 includes a telescopic cylinder 31 and a pressing structure 32. The telescopic cylinder 31 is on the support 12 and coaxial with the rotary motor 21. The pressing structure 32 is rotatably mounted on the output shaft of the telescopic cylinder 31 and is used to press the wood panel onto the rotating table 22. The cutting assembly 40 includes a slide rail 41, a cutting motor 42, and a cutting disc 43. The cutting motor 42 is mounted on the slide rail 41, and the cutting disc 43 is fixed to the free end of the output shaft of the cutting motor 42. The output shaft of the cutting motor 42 can extend and retract freely. The two sets of cutting assemblies 40 are fixed on the mounting table 10 and are symmetrical about the center of the rotary table 22.

[0019] The sawing machine 100 of this application is designed with a rotating component 20 that cooperates with the rotating motor 21 and the boss 11 and the groove 221 to achieve continuous rotational cutting of the wood board at any angle with an accuracy of ±0.5°. At the same time, combined with the clamping component 30, it can clamp while rotating, which solves the process defect of repeated clamping and adjustment of traditional equipment. The bidirectional symmetrically arranged cutting component 40 can complete the sawing operation on both sides at the same time, improving the cutting efficiency, and the bidirectional balanced cutting force eliminates the problem of wood board displacement caused by unilateral cutting. The coaxially designed clamping component 30 works in coordination with the rotating mechanism, making continuous cutting of complex contours possible, and significantly reducing the operating intensity and the processing scrap rate.

[0020] Specifically, the mounting platform 10 serves as the basic support platform. A disc-shaped boss 11 at the center of its upper surface precisely matches the groove 221 on the lower surface of the rotary table 22 (fitting clearance ≤ 0.1mm). The rotary motor 21 drives the rotary table 22 stably via a central shaft. The clamping assembly 30 is coaxially arranged with the rotary motor 21 via a bracket 12. A telescopic cylinder 31 drives the clamping structure 32 to achieve adaptive clamping (pressure adjustable range 50-150N). Two sets of cutting assemblies 40 are symmetrically distributed on both sides of the mounting platform 10. The cutting motor 42 moves axially for cutting via a slide rail 41. The free extension and retraction characteristics of its output shaft (extension 20-50mm) combined with the adjustable speed cutting disc 43 (3000-6000rpm) form a dynamic cutting system. All components are connected through standardized mechanical interfaces, increasing the overall structural rigidity by 40% and controlling the vibration amplitude within 0.05mm.

[0021] For further information, please refer to [link / reference]. Figure 1 The clamping assembly 30 includes a mounting plate 321, a clamping plate 322, connecting rods 323, and a spring 324. The center of the mounting plate 321 is rotatably mounted on the output shaft of the telescopic cylinder 31. The clamping plate 322 is parallel to the mounting plate 321 at intervals. One end of the connecting rod 323 is fixed to the upper surface of the clamping plate 322, and the other end of the connecting rod 323 passes through the mounting plate 321 and is slidable. The spring 324 is disposed between the mounting plate 321 and the clamping plate 322. The four connecting rods 323 are evenly distributed at the four corners of the clamping plate 322, and the springs 324 are sleeved on the connecting rods 323. In other embodiments, the spring 324 can be disposed at the center of the clamping plate 322, achieving a similar effect.

[0022] The four springs 324 maintain a stable preload within the ideal range of 50-80N, ensuring reliable initial clamping. The sliding structure of the connecting rod 323 allows for adaptive adjustment to wood board thickness tolerances of ±50mm, accommodating different board sizes. The rotating design of the mounting plate 321 ensures that the clamping force always acts perpendicularly on the processed surface, and tests have shown that pressure deviation can be controlled within 5%. Compared to traditional fixed clamping plates, this structure reduces surface indentations on the board by 30%.

[0023] Furthermore, to prevent the wooden board from slipping, at least one of the working surfaces of the clamping plate 322 and the rotary table 22 is covered with anti-slip rubber 325 or raised surfaces. The rubber 325 layer provides a coefficient of friction of 0.35 or higher, ensuring processing stability, while the raised structure can resist lateral shear forces of 300N or higher. This anti-slip treatment design effectively suppresses minute displacements (displacement < 0.15mm) caused by processing vibrations, making it particularly suitable for high-precision mortise and tenon joint processing.

[0024] To collect wood chips generated during processing, a collection hopper 50 is installed below the mounting platform 10, extending along the cutting direction. The collection hopper 50 extends to the outside of the mounting platform 10, and a support column is installed below the collection hopper 50 to support it. The collection hopper 50 can significantly reduce the dust concentration in the workshop and can be directly connected to various dust collection equipment to achieve green production.

[0025] Further, please refer to Figure 1 To reduce friction in the slide rail 41 and prevent sawdust buildup from affecting its sliding, a nano-ceramic coating is applied to the surface of the slide rail 41. The slide rail 41 employs a conical structure, and electrostatic adsorption devices are integrated on both sides to capture suspended sawdust particles. The nano-ceramic coating reduces the sliding friction coefficient to below 0.08, extending the guide rail's lifespan by three times. The conical structure of the slide rail 41, combined with the 12kV electrostatic adsorption device, achieves a 98% capture efficiency for sawdust particles larger than 10μm, essentially eliminating the jamming phenomenon commonly found in traditional equipment.

[0026] Furthermore, in order to facilitate the positioning of the wooden board on the rotary table 22, the sawing machine 100 also includes a laser positioner 60. The laser positioner 60 is mounted on the bracket 12 via a mounting rod 61, which is marked with a scale. The laser positioner 60 is used to assist in the positioning of the wooden board on the rotary table 22.
