Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and more specifically, to a wood chip collection device for wood cutting. Background Technology

[0002] In the wood processing industry, using a table saw for wood cutting is a common practice. However, in actual use, existing wood cutting equipment often lacks an efficient, integrated sawdust collection system, resulting in a harsh working environment and numerous problems, specifically: Wood chips generated during the cutting process are prone to flying everywhere, which not only pollutes the working environment and affects the operator's vision, but may also cause health hazards to the respiratory system. Meanwhile, the flying sawdust can easily accumulate at the base of the saw blade and around the motor, which may affect the normal rotation of the saw blade, increase the operating load of the motor, and hinder the heat dissipation of the motor, posing a safety hazard of overheating and damage to the equipment.

[0003] Therefore, in view of this, the existing structure is studied and improved to provide a wood chip collection device for wood cutting, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved In view of the problems existing in the prior art, the purpose of this utility model is to provide a wood chip collection device for wood cutting. It can improve the operator's vision, effectively reduce the health hazards to the operator's respiratory system, meet the occupational health and safety requirements of modern industrial production, reduce the operating load of the motor, extend the overall service life of the motor and saw blade, and improve the reliability and safety of equipment operation.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0006] A sawdust collection device for wood cutting includes a workbench, a grid plate fixedly installed on the top of the workbench, a protective box inside the workbench, a motor installed inside the protective box, and a saw blade connected to the output end of the motor via a coupling. The saw blade extends upward from the gaps in the grid plate to above the table surface of the grid plate, and a gantry frame is fixedly installed on the top of the grid plate, with the gantry frame directly above the saw blade. An air pump is fixedly installed on the side of the workbench. A three-way air pipe is fixedly connected to the air outlet of the air pump. The first outlet of the three-way air pipe is connected to a first jet pipe assembly, which is connected to the inside of the protective box. The second outlet of the three-way air pipe is connected to a second jet pipe assembly, which is connected to the bottom of the gantry frame. The workbench has a discharge port at its inner bottom, and a mounting frame is fixedly installed directly below the workbench. A storage drawer is installed on the mounting frame, and the opening of the storage drawer is located directly below the discharge port.

[0007] Furthermore, the first jet pipe assembly has its jets angled upwards toward the root of the saw blade, and the first jet pipe assembly consists of multiple parallel jet pipes.

[0008] Furthermore, the second jet pipe assembly is oriented towards the grid plate, and the second jet pipe assembly consists of multiple parallel jet pipes.

[0009] Furthermore, the storage drawer and the mounting rack are slidably connected, and the open area of ​​the storage drawer is larger than the opening area at the bottom of the discharge port.

[0010] Furthermore, two pull-out rods are fixedly installed at one end of the storage drawer, and the two pull-out rods are set at the same height and parallel to each other.

[0011] Furthermore, the discharge port is funnel-shaped, wider at the top and narrower at the bottom, and the inner wall of the discharge port has a smooth surface.

[0012] Furthermore, the slit width of the grid plate is slightly larger than the thickness of the saw blade.

[0013] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: ① This solution, through the physical obstruction of the gantry frame, combined with the cleaning of the grid plate by the first air jet assembly, and the immediate blowing of the second air jet assembly at the cutting point, fundamentally curbs the phenomenon of wood chips splashing towards the operator. The wood chips eventually enter the workbench through the mesh of the grid plate and are collected in the storage drawer. This significantly reduces the concentration of airborne dust in the work area, improves the operator's visibility, effectively reduces health hazards to the operator's respiratory system, and meets the occupational health and safety requirements of modern industrial production. ② This solution uses the first air jet assembly to directly purge the critical, easily clogged area at the base of the saw blade. This continuously prevents sawdust buildup, ensures good motor heat dissipation, avoids equipment failure or damage due to overheating, and reduces the operating load on the motor, thereby extending the overall service life of the motor and saw blade and improving the reliability and safety of equipment operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please see Figure 1 - Figure 4 A wood chip collection device for wood cutting includes a workbench 1, a grid plate 2 fixedly installed on the top of the workbench 1, a protective box 3 inside the workbench 1, a motor 4 inside the protective box 3, and a saw blade 401 connected to the output end of the motor 4 via a coupling. The saw blade 401 extends upward from the gaps in the grid plate 2 to above the table surface of the grid plate 2. The combination of workbench 1, grid plate 2, protective box 3, motor 4, and saw blade 401 constitutes a relatively safe cutting platform. Grid plate 2 allows sawdust to fall, while protective box 3 protects the motor 4 and transmission mechanism below.

[0018] A gantry frame 5 is fixedly installed at the top of the grid plate 2, and the gantry frame 5 is located directly above the saw blade 401; The gantry 5 provides protection for the operator to push the wood for cutting, greatly reducing the amount of wood chips flying during cutting.

[0019] An air pump 6 is fixedly installed on the side of the workbench 1. A three-way air pipe 601 is fixedly connected to the air outlet of the air pump 6. The first outlet of the three-way air pipe 601 is connected to the first jet pipe assembly 602. The first jet pipe assembly 602 is connected to the inside of the protective box 3. The second outlet of the three-way air pipe 601 is connected to the second jet pipe assembly 603. The second jet pipe assembly 603 is connected to the bottom of the gantry frame 5. The air pump 6, the three-way air duct 601, the first air jet assembly 602, and the second air jet assembly 603 constitute the core of the active collection system. By using air jets, the system can, on the one hand, remove sawdust from the base of the saw blade 401 inside the protective box 3, preventing its accumulation from affecting the heat dissipation of the motor 4 and the rotation of the saw blade 401; on the other hand, it can directly blow sawdust off at the cutting point below the gantry 5, causing it to fall through the mesh of the grid plate 2 into the workbench 1, thus achieving initial control and guidance of sawdust at its source.

[0020] The bottom of the workbench 1 is provided with a discharge port 7. A mounting frame 701 is fixedly installed directly below the workbench 1. A storage drawer 702 is installed on the mounting frame 701. The opening of the storage drawer 702 is located directly below the discharge port 7.

[0021] The discharge port 7, the mounting rack 701, and the storage drawer 702 constitute a sawdust collection and storage system. Sawdust blown down or falling naturally is collected through the discharge port 7 and eventually falls into the storage drawer 702. This design achieves centralized collection of sawdust, facilitating subsequent cleaning, maintaining a clean working environment, and preventing sawdust from accumulating inside the workbench 1.

[0022] See Figure 3 , Figure 4 Specifically, the air jets of the first jet pipe assembly 602 are angled upward toward the root of the saw blade 401.

[0023] It can most effectively disperse the sawdust in the critical areas that are most prone to accumulation and have the greatest impact on the operation of the saw blade 401 and the motor 4, ensuring good heat dissipation of the motor 4 and preventing the saw blade 401 from becoming unstable or overheating due to increased resistance.

[0024] Furthermore, the first jet pipe group 602 is composed of multiple jet pipes arranged in parallel.

[0025] This ensures a wider, more thorough airflow coverage, improving cleaning efficiency and reliability.

[0026] Specifically, the jet direction of the second jet pipe assembly 603 is set towards the grid plate 2.

[0027] It can blow the newly generated sawdust, which has not yet had time to fly, directly downwards into the gaps of the grid plate 2, allowing it to quickly enter the interior of the workbench 1. This greatly reduces the accumulation and flying of sawdust on the surface of the workbench 1, improving the working environment from the source.

[0028] Furthermore, the second jet pipe group 603 consists of multiple jet pipes arranged in parallel.

[0029] This ensures that the entire cutting area is covered, guaranteeing effective sawdust removal regardless of where the wood is cut under the gantry 5.

[0030] See Figure 2 Specifically, the storage drawer 702 and the mounting rack 701 are slidably connected.

[0031] The sliding connection makes it very convenient and quick to put in and take out the storage drawer 702, which facilitates the regular cleaning of the collected wood chips and greatly improves the ease of use and maintainability of the equipment.

[0032] Furthermore, the open area of ​​the storage drawer 702 is larger than the opening area at the bottom of the discharge port 7.

[0033] This ensures that all sawdust falling from the discharge port 7 falls accurately into the storage drawer 702, preventing sawdust from spilling outside the storage drawer 702 and guaranteeing collection efficiency.

[0034] Specifically, two pull rods 703 are fixedly installed at one end of the storage drawer 702, and the two pull rods 703 are set at the same height and parallel to each other.

[0035] It provides a clear and convenient point of force application, so that the operator does not need to put their hands under the storage drawer 702, which may contain residual sawdust. Pulling out and pushing back the storage drawer 702 is more effortless, convenient and hygienic.

[0036] See Figure 2 , Figure 3 Specifically, the discharge port 7 is a funnel shape that is wider at the top and narrower at the bottom, and the inner wall of the discharge port 7 has a smooth surface.

[0037] The funnel shape, wider at the top and narrower at the bottom, effectively guides and gathers scattered wood chips to a smaller outlet, playing a role in concentration and guidance, and preventing wood chips from accumulating inside the workbench 1.

[0038] At the same time, the smooth surface significantly reduces the friction and adhesion of wood chips when they fall, ensuring that the wood chips can slide smoothly into the storage drawer 702, effectively avoiding the problem of blockage in the discharge port 7 itself, and ensuring the continuous and stable operation of the collection system.

[0039] See Figure 1 , Figure 3Specifically, the gap width of the grid plate 2 is slightly larger than the thickness of the saw blade 401.

[0040] This ensures that the saw blade 401 can rotate freely in the gap without rubbing or colliding with the grid plate 2, while minimizing the gap as much as possible. This ensures safety and prevents small pieces of wood or larger wood chips from falling into the interior of the protective box 3 through the excessively large gap.

[0041] Working principle: When the operator places the wood on the grid plate 2 and pushes it toward the saw blade 401 for cutting, a large amount of wood chips are generated. The gantry 5, which is fixedly installed on the grid plate 2, firstly acts as a physical barrier, effectively suppressing the large-scale splashing of wood chips upward and forward, and confining most of the wood chips to the table surface area of ​​the workbench 1.

[0042] After the device is started, the air pump 6 begins to work, generating compressed airflow. The airflow is split through the three-way air guide pipe 601 to the first jet pipe group 602 and the second jet pipe group 603. The second jet pipe group 603 can blow the sawdust off the table surface as soon as it is generated and before it has gained enough kinetic energy to disperse, causing it to fall into the workbench 1 below through the gaps in the grid plate 2. This achieves real-time control of the sawdust from its generation source.

[0043] Simultaneously, the first air jet assembly 602 is introduced into the protective housing 3. The nozzle of this assembly is angled upwards and aimed at the root of the saw blade 401. The first air jet assembly 602 continuously blows air, which can effectively remove the accumulated debris in key areas, ensure good heat dissipation of the motor 4, guarantee the smooth and high-speed operation of the saw blade 401, and eliminate safety hazards.

[0044] All the wood chips that are blown off and fall naturally eventually collect at the bottom of the workbench 1.

[0045] The bottom of the workbench 1 is designed with a funnel-shaped discharge port 7, which is wider at the top and narrower at the bottom. This structure can effectively guide and concentrate the dispersed wood chips to the outlet. In addition, the inner wall of the discharge port 7 is smooth, allowing the wood chips to slide down smoothly and avoiding blockage.

[0046] Finally, the sawdust falls through the discharge port 7 into the storage drawer 702 directly below. The opening area of ​​the storage drawer 702 is larger than that of the discharge port 7, ensuring that all sawdust is received. When the storage drawer 702 is full, the operator can easily pull out the storage drawer 702 using the pull rod 703 to clean out the sawdust, and then push the storage drawer 702 back into its original position for continued use.

[0047] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
