[0021] Please see Figure 1 This application provides a cutting device 100 to prevent chipping during wood cutting. The device includes a workbench 10, a baffle structure 20, a protective cover 30, and two sets of pressure plate structures 40. A circular saw blade 11 driven by a motor is mounted on the workbench 10. The baffle structure 20 is located on the upper surface of the workbench 10 and on one side of the saw blade, used to adjust the width of the wood cutting. A bracket structure 50 is mounted on the surface of the workbench 10 and covers the saw blade. The protective cover 30 has symmetrically arranged protruding plates 31 on both sides. The pressure plate structures 40 are mounted on the protruding plates 31 and are used to press the wood on both sides of the cutting position to prevent chipping during cutting. The pressure plate structure 40 includes a support rod 41 slidably mounted on the protruding plate 31, a pressure plate 42 hinged to the bottom end of the support rod 41, and a spring 43 sleeved on the support rod 41. The center of gravity of the pressure plate 42 is located behind the hinge point in the cutting direction to achieve an inclined opening, and the support rod 41 is inclined relative to the horizontal plane.
[0022] The cutting device 100 of this application applies adaptive pressure to both sides of the wood cutting position through symmetrically arranged pressure plate structures 40, effectively suppressing edge chipping caused by wood fiber tearing. The center of gravity of the pressure plate 42 is designed to be located behind the hinge point, and together with the inclined support rod 41 and spring 43, it realizes automatic tensioning and follow-feeding of the pressure plate 42 during the cutting process. The structure requires no additional power, ensuring the flatness of the cut surface, reducing material waste, and significantly improving the quality and production efficiency of wood processing.
[0023] Specifically, please refer to Figure 1The worktable 10 is equipped with a circular saw blade driven by a motor, with the saw blade protruding significantly from the upper surface of the worktable 10. The rotation of the saw blade is driven by the motor, which is connected to the saw blade through a series of mechanical transmission devices. When the motor starts, it drives the saw blade to rotate at high speed, thereby achieving the cutting function. It is worth noting that the installation of the circular saw blade 11 on the worktable 10 and the fact that the saw blade is driven to rotate by a motor are both existing technologies, which have mature applications and widespread understanding in related fields. Therefore, they will not be described in detail or further explanation here.
[0024] A baffle structure 20 is located on the upper surface of the workbench 10, on one side of the saw blade, and is used to adjust the width of the cut wood planks. The baffle structure 20 includes a baffle 21, a locking stud 22, and a wing nut 23. Two through holes 211 are provided at both ends of the top surface of the baffle 21, penetrating both the top and bottom surfaces. The locking stud 22 passes through the workbench 10 from its lower surface, through the through holes 211, and extends beyond the top surface of the baffle 21. The wing nut 23 is located at the free end of the locking stud 22, and can be used to fix the baffle 21 to the workbench 10 by turning the wing nut 23.
[0025] Furthermore, the workbench 10 has two parallel and perpendicular slots 12. The lower end of the locking stud 22 is provided with a retaining part 221 that matches the shape of the slot 12, so that the locking stud 22 can be engaged in the slot 12 and slide along the direction of the slot 12. When it is necessary to adjust the distance between the baffle 21 and the saw blade, loosen the wing nut 23, move the baffle 21 to the required position, and then tighten it again to ensure stable operation of the device. The slot 12 can be a stepped slot, a dovetail slot, etc.
[0026] The protective cover 30 is securely mounted on the workbench 10 via the support structure 50. The protective cover 30 is a cover-shaped structure that covers the saw blade. The bottom surface of the protective cover 30 maintains a gap with the workbench 10 to allow the wooden board to pass through. The overall shape of the protective cover 30 is arc-shaped to match the protruding part of the saw blade, which is used to prevent the saw blade from causing accidental injury to people in the vicinity during operation.
[0027] Furthermore, in order to better maintain the stability of the entire structure, two sets of support structures 50 are set on the same side of the workbench 10 to jointly support the protective cover 30, so as to maintain the working stability of the protective cover 30.
[0028] Specifically, the support structure 50 includes a vertical plate 51 and a fixing rod 52. The vertical plate 51 is fixed to the edge of the workbench 10 and is on the same side as the baffle structure 20. One end of the fixing rod 52 is fixed to the vertical plate 51, and then the fixing rod 52 passes through the through hole 212 in the baffle 21, and the other end of the fixing rod 52 passes through the protective cover 30 and is fixed thereto. The protective cover 30 can rotate along one of the fixing rods 52.
[0029] A pressure plate structure 40 is installed on the protective cover 30 to press down the wooden board at the cut position, preventing chipping. Specifically, protruding plates 31 are formed on both sides of the protective cover 30 for the installation of two sets of pressure plate structures 40, which respectively press down on both sides of the cut wooden board. The pressure plate structure 40 includes a support rod 41, a pressure plate 42, and a spring 43. The upper end of the support rod 41 passes through the mounting plate and is slidable. The upper surface of the pressure plate 42 is hinged to the bottom end of the support rod 41 through a flange structure. The spring 43 is sleeved on the support rod 41, with one end of the spring 43 abutting against the lower surface of the mounting plate, and the other end of the spring 43 being limited and fixed by a protruding boss 411 on the support rod 41. The preload of the spring 43 is configured to maintain continuous contact between the pressure plate 42 and the surface of the wooden board when the wooden board passes through.
[0030] Furthermore, considering practical operation and functional requirements, the pressure plate 42 is designed with an offset center of gravity to facilitate wood cutting. Specifically, during the wood cutting process, the appropriate tilt design of the pressure plate 42 can greatly improve the convenience and efficiency of cutting. In the cutting direction, the center of gravity of the pressure plate 42 is located behind the hinge point, allowing it to automatically tilt during actual cutting due to the offset center of gravity. This automatic tilting effect allows the pressure plate 42 to open towards the wood, thus creating more favorable conditions for wood cutting, facilitating the cutting tools to smoothly cut the wood, and greatly improving the smoothness and convenience of the entire cutting process.
[0031] Furthermore, to ensure the pressure plate 42 can more stably press down on the wooden board, the support rod 41 is designed to be inclined relative to the horizontal plane. The inclination angle is [30, 45] degrees. The inclined state of the support rod 41 can share the force generated when the pressure plate 42 is squeezed by the wooden board. When the wooden board applies pressure to the pressure plate 42, the inclined support rod 41 will bear part of the pressure, thus allowing the support rod 41 to move slowly. This slow movement of the support rod 41 can further promote the pressure plate 42 to better press the wooden board, ensuring that the pressure plate 42 achieves a better pressing effect on the wooden board.
[0032] Furthermore, to effectively prevent the support rod 41 from rotating during use and ensure the stability and reliability of the entire device, the support rod 41 is designed as a square support rod 41. Its four sides are perpendicular to each other and at fixed angles, which better restricts its rotation compared to support rods of other shapes such as circles. Simultaneously, the mounting plate has openings corresponding to the square support rod 41 for sliding within them. This design allows the support rod 41 to slide smoothly within the openings without rotating, thus meeting the needs of practical use.
[0033] The working process of the cutting device 100 is as follows:
[0034] In actual operation, the wooden board to be cut is first placed on the workbench 10, and the distance between the baffle 21 and the saw blade is adjusted according to the required cutting width. By loosening the wing nut 23, the baffle 21 is moved to the appropriate position and then tightened again to ensure that the baffle 21 is firmly fixed, so as to achieve precise width control. Then, the motor is started to make the saw blade rotate at high speed, and the protective cover 30 is adjusted to an appropriate height to ensure that it fits tightly with the protruding part of the saw blade, thereby effectively preventing flying chips or accidental injuries that may be generated during the cutting process.
[0035] During the wood board cutting process, the pressure plate structure 40 begins to function. When the wood board contacts the pressure plate 42, due to the offset design of the pressure plate 42's center of gravity, the pressure plate 42 automatically tilts and opens to facilitate the wood board's entry, creating a stable pressing effect. The elasticity of the spring 43 further enhances the pressure of the pressure plate 42 on the wood board, ensuring a tight fit and preventing edge chipping caused by vibration or external forces. At the same time, the inclined design of the support rod 41 distributes some of the pressure on the pressure plate 42, making the entire pressing process smoother and more efficient.
[0036] To ensure cutting quality, the protective cover 30 and the support structure 50 provide additional safety as the plank passes through the saw blade. The curved design of the protective cover 30 not only matches the shape of the saw blade but also provides sufficient space for the plank to pass smoothly, avoiding jamming or cutting deviations caused by insufficient space. In addition, the two symmetrically arranged support structures 50 ensure the stability of the protective cover 30 during operation, preventing shaking or displacement due to external interference.
[0037] Throughout the entire cutting process, all components work together, from width adjustment and pressure stabilization to safety protection, demonstrating the scientific and practical design of the device. This cutting device 100, which prevents chipping during wood cutting, not only significantly improves the quality and efficiency of wood processing but also greatly reduces material waste caused by chipping, providing the wood processing industry with an efficient and reliable solution.
