Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood cutting equipment technology, and more specifically, to a wood cutting device for furniture manufacturing. Background Technology
[0002] In the furniture manufacturing industry, wood cutting is a crucial process, and its efficiency and quality directly impact the quality of the final product. With the advent of the Industrial Revolution, mechanized cutting equipment gradually replaced traditional hand tools, greatly improving production efficiency and product consistency. However, despite the significant progress brought by mechanization, modern wood cutting equipment still faces many challenges in practical applications. Especially when processing large quantities of wood, the sawdust and dust generated during the cutting process become a significant problem. These debris not only affect the cleanliness of the working environment but may also pose a threat to the health of operators.
[0003] Existing dust collection systems in wood cutting equipment typically consist of only a simple suction device, which is insufficient to effectively capture most of the fine dust particles ejected by the high-speed rotating cutting blade. This results in dust permeating the entire workspace, increasing the risk of air pollution. Furthermore, due to the lack of an effective airflow mechanism, existing suction devices struggle to efficiently collect sawdust and dust generated during the cutting process, leading to unsatisfactory overall dust removal efficiency. This limitation not only affects the cleanliness of the working environment but also poses a potential health risk to operators. Utility Model Content
[0004] The purpose of this invention is to provide a wood cutting device for furniture manufacturing, which solves the problem that existing air extraction devices are not effective in capturing wood chips and dust, and significantly improves dust removal efficiency and the cleanliness of the working environment.
[0005] To achieve the above objectives, a wood cutting device for furniture manufacturing is provided, including a base, a wood placement area in the center of the base, a support seat on one side of the upper end of the base, a cutting blade that is movably mounted on the support seat above the wood placement area, a drive motor that is fixedly connected to one end of the cutting blade via a connecting column, and a protective cover that covers the cutting blade on one side of the connecting column.
[0006] An exhaust pipe is connected to the center of the upper part of the protective cover. The exhaust pipe includes a corrugated hose. The protective cover includes an arc-shaped body and a flat body. The arc-shaped body has several convex guide plates inside, and the flat body has several flat guide plates inside. The flat guide plates are set at a 30° angle towards the exhaust pipe to carry the dust generated during the cutting process into the dust collection box.
[0007] As a further improvement to this technical solution, an air inlet plate is inserted at the upper end of the protective cover below the air extraction pipe, and the air inlet plate is provided with several filter holes.
[0008] As a further improvement to this technical solution, the support base is provided with a fixing plate on the upper side of the protective cover, and a dust collection box is provided on the upper part of the fixing plate, with the upper end of the exhaust pipe connected to the dust collection box.
[0009] As a further improvement to this technical solution, an adjustment motor is inserted at the top of the support base, and a threaded rod is fixedly connected to the lower output end of the adjustment motor. A nut plate is threadedly connected to the threaded rod, and a connecting plate is fixedly connected to the lower end of the nut plate. The drive motor is inserted on the connecting plate.
[0010] As a further improvement to this technical solution, two limiting seats are symmetrically provided on both sides of the cutting blade at the upper end of the base. A cylinder is inserted into the top of the limiting seat, with the cylinder output end facing downwards. A clamp is fixedly provided at the cylinder output end.
[0011] As a further improvement to this technical solution, a cutting groove is provided at the lower end of the base corresponding to the cutting blade.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. The optimized dust collection system in this furniture manufacturing wood cutting device significantly improves equipment performance. Specifically, two different types of guide plates are installed inside the protective cover: a convex guide plate and a flat guide plate. The convex guide plate is located on the inner side of the arc-shaped body of the protective cover, and its shape helps guide larger wood chips along the arc-shaped path and concentrate them towards the exhaust pipe. The flat guide plate is installed on the flat part of the protective cover, arranged at a 30-degree angle towards the exhaust pipe. This angled design allows for smoother airflow and effectively guides fine dust particles generated during cutting to the exhaust pipe, and then into the dust collection box. The two guide plates work together to not only improve the collection efficiency of dust and wood chips, but also reduce particulate matter in the air, ensuring a clean working environment.
[0014] 2. This furniture manufacturing wood cutting device is equipped with a robust wood fixing mechanism. Two symmetrical limit seats are located on both sides of the base, each with a cylinder and a gripper at its top. During cutting, the cylinder extends downwards and the gripper firmly grasps the wood to be cut, ensuring its stability throughout the process. Simultaneously, an adjusting motor inserted at the top of the support seat precisely adjusts the height of the cutting blade via a threaded rod and nut plate to accommodate wood of varying thicknesses. This design not only improves cutting accuracy and reduces the risk of cutting errors or accidental injury caused by wood movement, but also supports rapid loading and unloading of materials, significantly enhancing overall work efficiency.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0024] Please see Figure 1 As shown, the purpose of this embodiment is to provide a wood cutting device for furniture manufacturing, including a base 1 with a wood placement area in the center for stably placing the wood to be cut. A support 3 is provided on one side of the base 1, and a cutting blade 12 that can move up and down is installed on the support 3. The blade is driven by a drive motor 8 through a connecting column 13 to rotate and perform the cutting operation. In order to prevent wood chips from flying during the cutting process and to improve the safety and cleanliness of the working environment, a protective cover 11 is installed on one side of the cutting blade 12. The protective cover 11 not only covers the cutting blade 12, but also integrates an exhaust pipe 10 for immediate collection of dust and debris into a dust collection box 9.
[0025] like Figure 3 , Figure 4 As shown, the protective cover 11 is designed with a unique combination of an arc-shaped body 18 and a flat body 20, aiming to optimize the collection efficiency of wood chips and dust generated during the cutting process. This design is not arbitrary, but based on in-depth research and analysis of the flow characteristics of wood chips and dust during the cutting process.
[0026] The arc-shaped body 18 is designed primarily to effectively manage the flow and speed of larger wood chips. During wood cutting, larger wood chips often fly out at high speeds. If these chips directly impact the dust collection system or other equipment, they may cause blockages or damage. The curvature of the arc-shaped body 18 guides these large wood chips along an arc-shaped path, thereby slowing their speed and concentrating their flow towards the extraction pipe 10. The convex guide plate 19 is carefully arranged inside the arc-shaped body 18. Its raised structure increases the contact area between the wood chips and the guide plate, helping to disperse the kinetic energy of the wood chips and allowing them to slide more smoothly towards the extraction pipe 10. In addition, this design reduces the possibility of wood chips bouncing back or remaining inside the protective cover 11, ensuring that most of the wood chips are successfully collected into the dust collection box 9.
[0027] The planar body 20 is designed to complement the layout and operational requirements of the cutting mechanism. It provides a flat working surface, allowing the cutting blade 12 to move smoothly up and down, ensuring a clear view during the cutting process and facilitating operator observation and control of the cutting progress. The planar body 20 contains several planar guide vanes 21 arranged at a 30-degree angle towards the exhaust pipe 10. This angle is precisely calculated to ensure sufficient airflow while avoiding excessive resistance, preventing fine dust from accumulating inside the protective cover 11 or escaping into the air. The 30-degree angle also promotes a more uniform pressure distribution in the airflow, improving overall dust collection efficiency and effectively guiding fine dust particles generated during cutting to the exhaust pipe 10 and then into the dust collection box 9. The two guide vanes work together to significantly improve the collection efficiency of dust and sawdust. This integrated design not only reduces airborne particulate matter and ensures a clean working environment but also enhances the overall performance of the equipment, providing operators with healthier and safer working conditions.
[0028] Furthermore, the extraction tube 10 is in the shape of a corrugated flexible tube, such as... Figure 2 As shown, the support base 3 has a fixing plate 17 on the upper side of the protective cover 11. A dust collection box 9 is located on the upper end of the fixing plate 17, and the upper end of the exhaust pipe 10 connects to the dust collection box 9. An air inlet plate 22 is inserted below the exhaust pipe 10 on the upper end of the protective cover 11. The air inlet plate 22 has several filter holes 23, allowing airflow while preventing larger wood chips from directly entering the pipe and causing blockage. This not only ensures the normal operation of the exhaust system but also extends the service life of the equipment. Furthermore, an adjusting motor 4 is inserted at the top of the support base 3. A threaded rod 5 is fixedly connected to the lower output end of the adjusting motor 4. A nut plate 6 is threaded onto the threaded rod 5, and a connecting plate 7 is fixedly connected to the lower end of the nut plate 6. A drive motor 8 is inserted into the connecting plate 7. By adjusting the motor 4, the user can flexibly adjust the cutting depth according to actual needs, adapting to the cutting requirements of wood of different thicknesses and ensuring optimal results for each cut.
[0029] To ensure the stability of the wood to be cut, two symmetrically positioned limiting seats 2 are provided on the base 1, with a cylinder 14 inserted at the top of each limiting seat 2. When the wood needs to be fixed, the cylinder 14 extends downward, and the clamp 15 fixed at its output end firmly grips the wood, ensuring that the wood remains stable throughout the cutting process. This robust fixing mechanism not only improves cutting accuracy and reduces the risk of cutting errors or accidental injury caused by wood movement, but also supports quick loading and unloading of materials, improving overall work efficiency. A cutting groove 16 is provided below the cutting blade 12 on the base 1, providing the necessary space for the cutting blade 12 to perform cutting operations smoothly on the base 1, helping to guide waste material out and preventing accumulation that could affect operation.
[0030] In summary, this wood cutting device for furniture manufacturing achieves a cleaner and safer working environment through the combined action of its various components. From the efficient dust extraction system and robust fixing mechanism to precise cutting control, every part of the design is dedicated to improving work efficiency and quality. In particular, the deflector design within the protective cover 11 and the application of intelligent sensing technology significantly enhance dust collection while ensuring the health and safety of operators. This series of innovative designs is not only suitable for furniture manufacturing sites of all sizes but also provides the industry with new standards and technical references.
