Description

Technical Field

[0001] This utility model relates to the field of structural core material processing technology, specifically to a wood chip cleaning device. Background Technology

[0002] Wind turbine blades are the core components of wind turbine generators, and their performance directly affects the efficiency of converting wind energy into electrical energy. The blade core material is a critical component of the blade. By employing a sandwich structure in the leading edge, trailing edge, and web of the blade, the blade's weight can be reduced, structural stiffness increased, and local instability prevented, thereby improving the overall load-bearing capacity of the blade. This requires reducing blade weight while ensuring blade stability, and increasing the wind-catching area while meeting stiffness requirements.

[0003] Because wind turbine blades are designed according to complex aerodynamic principles and mechanical performance requirements, their contours are typically irregular, resulting in irregular shapes for the inner walls of the blade cavity. To achieve a good fit between the core material and the inner wall of the wind turbine blade, and to ensure the stability and reliability of the overall blade structure, precise cutting and chamfering of the core material are usually required. Specifically, the core material is typically cut into multiple small pieces to better fit the complex and varied contours of the inner wall; simultaneously, the core material is chamfered to create a structure with specific bevels. This irregular inner wall design of the wind turbine blade means that the slope of the beveled structure on the core material is not constant, but varies as the bevel extends.

[0004] In existing technologies, foam beveling machines are mainly used to cut the core material, enabling large-scale beveling of the core material. However, existing foam beveling machines can only process beveled structures with a fixed slope, and cannot process beveled structures with varying slopes. This makes it difficult for the core material to perfectly fit the irregular inner wall of the wind turbine blade. This not only affects the overall stability of the blade structure, but also easily leads to local stress concentration, reducing the blade's load-bearing capacity and service life. Therefore, in order to fit the inner wall as closely as possible, additional manual grinding or cutting of the core material is required, which greatly increases the labor and time costs of production and reduces production efficiency. At the same time, manual grinding or cutting heavily relies on the operator's experience and skills, which can easily lead to problems such as dimensional deviations. Manual intervention not only increases labor intensity, but more importantly, frequent manual adjustments of the cutting tools are time-consuming, seriously affecting overall production efficiency.

[0005] To address this issue, the inventors developed a wood cutting machine capable of batch processing inclined surfaces with varying slopes, significantly reducing human intervention. Simultaneously, to efficiently and reliably collect and process the sawdust generated during core material cutting, preventing this waste from accelerating saw blade wear and affecting the cutting accuracy, the inventors designed a sawdust cleaning device for this wood cutting machine.

The board cutting equipment includes a workbench and a cutting mechanism for cutting core boards located on the workbench. The wood chip cleaning device includes a crusher, an air blowing assembly, and a dust collection assembly. The crusher includes a housing and a set of crushing blades disposed inside the housing. The collection port at the top of the housing fits tightly against the edge of the workbench and is adapted to the cutting area of ​​the workbench, for guiding the cut waste into the housing.

[0044] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] This embodiment provides a wood chip cleaning device, such as Figures 1-7As shown, a board cutting device is used, comprising a workbench 3 and a cutting mechanism 14 for cutting a core board 001 located on the workbench 3; a wood chip cleaning device includes a crusher, an air blowing assembly, and a dust collection assembly; the crusher includes a housing 21 and a set of crushing blades 22 disposed inside the housing 21; the collection port 211 at the top of the housing 21 is tightly fitted to the edge of the workbench 3 and adapted to the cutting operation area of ​​the workbench 3, for guiding the cut waste into the housing 21; the air blowing assembly is mounted on the workbench 3 via a first support structure. The air supply assembly is located above or to the side of the cutting work area and can be connected to the air source 05 via the air supply duct 01; the air blowing assembly has an air blowing port 231 facing the cutting work area, and the airflow direction of the air blowing port 231 is directed towards the collection port 211, for blowing waste into the box 21; the dust suction assembly is mounted above or to the side of the cutting work area of ​​the workbench 3 via the second support structure and can be connected to the dust collection equipment via the first dust collection duct 02; the dust suction assembly has a first dust suction port 261 facing the cutting work area, for absorbing the dust generated during the cutting process.

[0046] In this embodiment, the crusher can be selected from or modified from existing mature products. The opening plane of the collection port 211 is flush with or transitionally connected to the surface of the workbench 3. The collection port 211 can be a rectangular opening, slightly larger than the cutting area, to ensure that the waste generated during cutting can fall into it. The bottom of the box 21 has a certain depth for storing the crushed waste; alternatively, the bottom of the box 21 can also be connected to a collection device, such as a hopper or a removable drawer, for easy cleaning of the crushed wood chips. The air source 05 refers to equipment that provides compressed air or high-pressure gas, such as an air compressor or blower. The airflow is delivered to the air outlet 231 through the air supply pipe 01 to blow the waste. The specific structure of the air supply pipe 01 and the air source 05 can be found in related technologies and will not be described in detail here. To improve the space utilization of the equipment, the blower, etc., can be placed below the workbench 3, thereby saving space. Dust collection equipment (not shown in the figure) refers to a woodworking central dust collector or industrial dust collector equipped with negative pressure in a woodworking workshop. The first dust collection pipe 02 and the dust collection equipment can be found in relevant technologies, and will not be described in detail here.

[0047] In this embodiment, the wood chip cleaning device is used by activating the air blowing assembly and the dust suction assembly. This causes the air blowing port 231 to generate an airflow directed towards the collection port 211, and the first dust suction port 261 to begin suction. The crusher is in standby mode. The cutting mechanism 14 cuts the core board 001. During the cutting process, larger pieces of scrap material fall directly into the collection port 211, which is attached to the edge of the worktable 3, by gravity and enter the crusher housing 21. At the same time, the airflow generated by the air blowing port 231 of the air blowing assembly blows lighter and smaller wood chips, larger pieces of scrap material that do not fall directly into the collection port 211 by gravity, and other waste materials into the collection port 211, further ensuring that the waste enters the crusher. Meanwhile, the first dust suction port 261 of the dust suction assembly absorbs the fine dust generated during the cutting process and quickly removes it from the cutting area to prevent it from spreading into the air. The waste material entering the housing 21 is crushed by the crushing blade assembly 22, which breaks it into smaller and more uniform particles or fibers for easier subsequent processing.

[0048] The wood chip cleaning device in this embodiment blows the waste generated during cutting into the housing 21 through an air blowing component, while a dust suction component absorbs the dust generated during the cutting process. This effectively reduces the scattering of waste and dust, improves waste collection efficiency and working environment quality, reduces wear and corrosion of the cutting mechanism 14 and other components by dust, extends the service life of the equipment, and lowers maintenance costs. The crushing blade assembly 22 can crush large pieces of waste, significantly reducing the waste volume, facilitating storage and transportation, and laying the foundation for the energy utilization (such as making biomass fuel) or reuse (such as making particleboard and MDF raw materials) of the waste.

[0049] The sawdust cleaning device of this embodiment is characterized in that, Figures 3-7 As shown, the dust collection assembly includes a dust collection hood 26, a first dust collection port 261 and a dust discharge port 262 communicating with the first dust collection port 261, and the dust discharge port 262 can be connected to a dust collection device through a first dust collection pipe 02.

[0050] In this embodiment, the shape and size of the dust collection hood 26 can be designed according to the type of cutting mechanism 14 and the characteristics of the cutting operation area, for example, it can be flared, flat box-shaped, or arc-shaped. The dust collection hood 26 is connected to the dust collection equipment through the first dust collection pipe 02 to ensure sufficient negative pressure suction. The first dust collection port 261 can be located close to the cutting point to maximize the capture of dust generated during the cutting process. The dust discharge port 262 can be provided with a connector for connecting to the first dust collection pipe 02. The connector and the first dust collection pipe 02 can be plugged in and fixed by a clamp.

[0051] The wood chip cleaning device of this embodiment, such as Figures 3-7As shown, the cutting mechanism 14 includes a saw blade motor 142 and a circular saw 141 installed at the output end of the saw blade motor 142; the second support structure includes a fixed beam 27, which is fixedly connected to the housing of the saw blade motor 142, and the dust suction hood 26 is fixedly installed on the fixed beam 27; preferably, the first dust suction port 261 is located near the edge of the circular saw 141.

[0052] In this embodiment, the fixed beam 27 is made of high-strength materials (such as steel or aluminum alloy) and has sufficient rigidity. The fixed beam 27 is firmly connected to the housing of the saw blade motor 142 by bolts, welding, or clamps, allowing the fixed beam 27 to move synchronously with the cutting mechanism 14. The dust suction hood 26 is fixedly installed on the fixed beam 27, ensuring that its first dust suction port 261 is always near the cutting point of the circular saw 141, precisely linked with the cutting action. The linkage design between the dust suction hood 26 and the cutting mechanism 14 ensures that no matter where the cutting mechanism 14 moves to for cutting, the first dust suction port 261 always follows the cutting point, achieving "where it cuts, it sucks up dust," greatly improving the dust capture rate. Utilizing the structure of the cutting mechanism 14 itself for support reduces additional independent support components, making the entire device structure more compact and saving space.

[0053] The sawdust cleaning device of this embodiment, further, such as Figure 3 As shown, it also includes a enclosure assembly, which includes a front baffle 251 and a side baffle 252; the front baffle 251 is vertically disposed on the edge of the collection port 211 away from the worktable 3, and the upper edge of the front baffle 251 is higher than the upper edge of the core plate to be cut; there are two side baffles 252, which are vertically disposed opposite each other on the two sides of the collection port 211, and the upper edge of the side baffle 252 is higher than the upper edge of the core plate to be cut.

[0054] In this embodiment, the front baffle 251 and the side baffles 252 can be made of metal plates, high-strength plastic plates, etc., and are arranged vertically. The front baffle 251 and the two side baffles 252 together form a "U"-shaped or three-sided enclosed area above the collection port 211. The enclosure assembly can effectively limit the dispersion of cutting waste outside the collection port 211, guiding it to enter the collection port 211 and the crusher more concentratedly. At the same time, the front baffle 251 and the side baffles 252 help to form a relatively enclosed space, making the airflow of the blowing assembly more concentrated in it, enhancing the efficiency of blowing waste into the collection port 211, and also limiting the diffusion of dust in the cutting operation area to a certain extent, helping the dust collection assembly to capture dust more effectively.

[0055] The sawdust cleaning device of this embodiment, further, such as Figure 3As shown, the positive baffle 251 is provided with a second dust suction port 2511, which can be connected to the dust collection equipment through the second dust collection pipe 03; the second dust suction port 2511 faces the cutting operation area and is used to absorb the dust generated during the cutting process.

[0056] In this embodiment, the second dust suction port 2511 can be circular, rectangular, or slit-shaped. The second dust suction port 2511 is connected to an external dust collection device via the second dust collection pipe 03. A connector can be provided on the side of the baffle 251 away from the collection port 211 for connecting to the second dust collection pipe 03. The connector and the second dust collection pipe 03 can be plugged in and fixed with clamps. This dust collection device can be the same device connected to the first dust collection pipe 02, or it can be an independent auxiliary dust collection device, depending on the amount of dust generated and the cleaning requirements. The second dust suction port 2511 points towards the cutting operation area, further capturing and absorbing the dust generated during the cutting process, achieving more comprehensive dust coverage of the cutting operation area, significantly improving the dust removal rate of the entire device, and further improving the working environment.

[0057] The sawdust cleaning device of this embodiment, further, such as Figure 4 , Figure 5 As shown, the bottom of the housing 21 is provided with a conveying port 212, which can be connected to the dust collection equipment through the third dust collection pipe 04, and is used to guide the waste material after being crushed by the crushing blade group 22 into the dust collection equipment.

[0058] In this embodiment, the conveying port 212 can be located at the bottom of the crusher housing 21, serving as the outlet for the crushed waste. Its size and shape are designed according to the crushed particle size of the waste and the subsequent conveying method; for example, it can be a circular or rectangular opening. The conveying port 212 is connected to a dust collection device via a third dust collection pipe 04. This dust collection device can be the same device connected to the first dust collection pipe 02, or it can be an independent auxiliary dust collection device with negative pressure. The crushed waste enters the dust collection device through negative pressure suction. The housing 21 can be equipped with a connector for connecting to the third dust collection pipe 04. The connector and the third dust collection pipe 04 can be plugged in and fixed with clamps. The waste, after being crushed by the crushing blade assembly 22, directly enters the dust collection device through the conveying port 212 and the third dust collection pipe 04, achieving automated and continuous waste transfer, reducing secondary dust generation that may occur during the transfer of crushed waste, and maintaining a clean workshop environment.

[0059] The wood chip cleaning device of this embodiment, such as Figure 3 , Figure 4As shown, the air blowing assembly further includes an air guide shroud 23 and an air guide plate 24; the air guide shroud 23 is provided with the air blowing port 231 and an air inlet 232 communicating with the air blowing port 231; the air inlet 232 can be connected to the air source 05 through the air supply pipe 01; the air guide plate 24, at least one piece, is installed inside the air guide shroud 23 and located at the position of the air blowing port 231.

[0060] In this embodiment, an airflow channel is formed inside the air guide shroud 23. The geometry of the air guide shroud 23 (such as fan-shaped, duckbill-shaped, or elongated) is designed according to the size and shape of the required blowing area, aiming to optimize the distribution and directionality of the airflow. The air guide plate 24 is used to adjust the direction, diffusion angle, or speed distribution of the airflow. By adjusting the angle and number of air guide plates, the blown airflow can be more accurately directed towards the collection port 211 and cover the required blowing area, thereby more effectively pushing the waste. The air inlet 232 may be provided with a connector for connecting to the air supply duct 01. The connector and the air supply duct 01 can be plugged in and fixed by clamps. The combined use of the air guide shroud 23 and the air guide plate 24 ensures that the airflow is concentrated on the target waste, reducing airflow waste and ineffective diffusion.

[0061] The sawdust cleaning device of this embodiment, further, such as Figure 1 , Figure 2 As shown, it also includes a machine cover 28, which covers the plate cutting equipment to form an installation space 281; the cutting mechanism 14, the collection port 211, and the air guide hood 23 are all located within the installation space 281, the workbench 3 is at least partially located within the installation space 281, and a core board feed port 282 is formed between the bottom of the machine cover 28 and the upper surface of the workbench 3; the machine cover 28 is provided with a plurality of pipe holes 283.

[0062] In this embodiment, the machine cover 28 is made of metal sheet or composite material and has functions such as sound insulation, dust prevention, and safety protection. The core components, such as the cutting mechanism 14, the collection port 211, and the air guide hood 23, or their main working areas, are all located within the installation space 281. The workbench 3 is at least partially located within the installation space 281 and is used to support the core board to be cut. A core board feed port 282 is designed between the bottom of the machine cover 28 and the upper surface of the workbench 3 for feeding the core board into and out of the cutting area. This feed port 282 is typically designed to minimize dust spillage and may be equipped with brush strips or flexible baffles. Several pipe holes 283 are provided on the machine cover 28 for passing through the air supply duct 01, the first dust collection duct 02, the second dust collection duct 03, and the third dust collection duct 04, as well as other necessary cable conduits (such as power lines and control lines). The machine cover 28 forms a sealed space, greatly limiting the spillage of dust and waste generated during the cutting process, controlling pollution diffusion at the source, and making the entire system more environmentally friendly. The cover 28 provides a physical barrier to prevent operators from directly contacting the high-speed rotating cutting mechanism, thus improving operational safety. The cover 28 also effectively reduces noise generated during the operation of the cutting equipment, improving the acoustic environment of the workshop.

[0063] In this embodiment of the wood chip cleaning device, the first support structure is the inner wall of the machine cover 28, and the air guide shroud 23 is fixedly installed on the inner wall of the machine cover 28.

[0064] In this embodiment, the air guide shroud 23 is directly fixed to the inner wall of the housing 28 by bolts, welding, or adhesive bonding, and the air inlet 232 can be directly covered on the corresponding pipe hole 283. The air guide shroud 23 is directly fixed to the inner wall of the housing, and its position is precise and stable, and it will not easily shift due to external vibration.

[0065] The sawdust cleaning device of this embodiment, further, such as Figures 3-5 As shown, the box 21 slopes downward and converges around the inner wall of the collection port 211, forming a funnel-shaped guide area that is larger at the top and smaller at the bottom.

[0066] In this embodiment, the funnel-shaped guide zone can be designed as a smooth cone, pyramid, or stepped constriction to ensure that waste can slide down smoothly. Utilizing gravity, the funnel-shaped guide zone effectively guides various types of waste entering from the collection port 211 smoothly towards the crushing blade assembly 22, preventing waste from accumulating or getting stuck at the box inlet. The inclined inner wall design reduces friction and resistance of waste in the box inlet area, thereby reducing the risk of blockage and ensuring the continuous and stable operation of the crusher.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
