[0056] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0057] In the description of the application, it should be understood that the orientation or positional relationships indicated by the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end portion", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0058] In addition, in the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0059] When the existing panel saw cuts the board, a large amount of debris and dust will be generated at the cutting position of the board. It is provided with a number of dust-proof curtains composed of dust-proof strips on both sides of the pressure beam. During the process of the board entering and leaving the workbench, the dust-proof strips can close the aisle between the pressure beam and the workbench by bending. However, the deformation differences between the dust-proof strips result in large gaps between adjacent dust-proof strips. At the same time, the space between the pressure beam and the workbench is not completely sealed. Therefore, when cutting the board, the wood chips and dust fly at high speed during cutting and are likely to escape from the gaps, scattering on the surface of the workbench or the board. Larger wood chips and dust are likely to damage the board, causing quality accidents and spreading outwards. Moreover, debris and dust are likely to accumulate on the surface of the workbench, causing damage to devices such as bearings, cylinders, and motors, affecting the performance, life, and stability of the equipment. To solve the above technical problems, the embodiment of this application provides a dust removal device for a panel saw, which can quickly remove the wood chips and dust on the surface of the workbench through the first dust suction port, and achieve the sealing treatment of the board cutting through the dust-proof component, effectively preventing the leakage and diffusion of wood chips and dust, improving the dust suction effect of the second dust suction port, and further enhancing the cleanliness of the panel saw.

[0060] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0061] As Figures 1 to 5 shown, the embodiment of this application provides a dust removal device for a panel saw. The panel saw 1 has a workbench 2, a measuring rule 3 provided on one side of the workbench 2, and a pressure beam 4 located above the workbench 2. The workbench 2 has a saw kerf 20 and a number of air outlets 21. The pressure beam 4 and the workbench 2 form an aisle for the board 8 to travel through, including:

[0062] A dust-proof component 5 is provided on both sides of the pressure beam 4 along the traveling direction of the board 8. The dust-proof component 5 has a closed state for closing the aisle and an open state for opening the aisle;

[0063] A driving component 6 is used to drive the dust-proof component 5 to switch between the closed state and the open state;

[0064] The measuring rule 3 is provided with a first dust suction port 30, the pressure beam 4 is provided with a second dust suction port 40. Some of the air outlets 21 are provided with pneumatic floating beads, and the remaining air outlets 21 are provided with an air outlet component 7, and the air outlet direction of the air outlet component 7 faces the first dust suction port 30.

[0065] Specifically, the workbench 2 of the panel saw 1 serves as the working area for sawing the board 8. The pressure beam 4 is located above the workbench 2. The saw kerf 20 of the workbench 2 is the route for the saw blade to travel and saw the board. The stop fence 3 is located at the end of the saw kerf 20 and below the pressure beam 4. One side of the board 8 abuts against the stop fence 3. The bottom end face of the pressure beam 4 is used to press against the board 8, and this end face and the surface of the workbench 2 form an aisle through which the board 8 can freely pass. The dust-proof components 5 are arranged on both sides of the pressure beam 4 and can be closed and opened at both ends of the aisle under the drive of the drive component 6. The pusher device of the panel saw 1 pushes the board 8 under the pressure beam 4. After the board 8 is in place, the pressure beam 4 descends to tightly fix the board 8. The sawing mechanism reciprocates in the saw kerf 20 to saw the board 8. The dust-proof components 5 close this space to improve the sealing of the aisle. The stop fence 3 is designed as a hollow structure. The hollow structure inside the stop fence 3 is connected to the air suction device. There are multiple first dust suction ports 30 on the side of the stop fence 3 facing the board 8. The pneumatic floating beads on the air outlet 21 are in rolling contact with the board. Some of the air outlets 21 are provided with an air outlet component 7. The air outlet component 7 is connected to a air supply device, such as a blower. The air outlet direction of the air outlet component 7 faces the first dust suction ports 30. The lower surface of the board 8 and the upper surface of the workbench 2 form a flat gas channel. When the air supply device blows air through the air outlet component 7, the air flows in this gas channel, which will drive the wood chips and dust located in this gas channel to flow to the vicinity of the first dust suction ports 30. Under the action of the air suction device, they are sucked into the stop fence 3 and the dust is collected through the collection device.

[0066] In this embodiment, some of the air outlets 21 on the workbench 2 are installed with the air outlet component 7, and the air outlet direction of the air outlet component 7 faces the first dust suction ports 30. The dust-proof components 5 of the dust removal device can improve the sealing effect between the pressure beam 4, the board 8 and the workbench 2, ensuring that the wood chips and dust will not escape and spread to the external environment. During the sawing process of the board 8, the air outlet component 7 blows the wood chips and dust on the workbench 2 towards the first dust suction ports 30. Under the combined action of the first dust suction ports 30 and the second dust suction ports 40, it is ensured that the wood chips and dust can be effectively sucked away. The dust-proof components 5 can enter the open state under the drive of the drive component 6, thereby opening the aisle, and the pusher device of the panel saw 1 can push the board 8 onto the workbench. After the board 8 is in place, the pressure beam 4 descends, and the dust-proof components 5 are converted from the open state to the closed state under the drive of the drive component 6, closing the aisle. When the board 8 is in place and the dust-proof components 5 are all in the closed state, the pressure beam 4, the workbench 2 and the dust-proof components 5 together form a closed space, ensuring that the wood chips and dust generated during the sawing of the board 8 will not escape from this closed space and spread to the external environment, significantly improving the cleanliness of the panel saw 1 and providing a good protection effect for the health of the operator.

[0067] As Figure 6 and Figure 7As shown, the above aisle has a first aisle entrance and a second aisle entrance;

[0068] The dust-proof component 5 includes a rotating component 51 and a lifting component 52, and the driving component 6 includes a first driving member 61 and a second driving member 62;

[0069] The first driving member 61 drives the rotating component 51 to rotate, so that the rotating component 51 closes or opens the first aisle entrance;

[0070] The second driving member 62 drives the lifting component 52 to lift, so that the lifting component 52 closes or opens the second aisle entrance.

[0071] Specifically, the aisle has an entrance area where the plate 8 enters and an exit area where it leaves. The first aisle entrance can be the entrance area or the exit area. Correspondingly, the second aisle entrance is the exit area or the entrance area. The installation positions of the rotating component 51 and the lifting component 52 can be selected according to actual needs. For example, the rotating component 51 is installed in the exit area, and the lifting component 52 is installed in the entrance area, or the rotating component 51 is installed in the entrance area, and the lifting component 52 is installed in the exit area. After the plate 8 enters the workbench 2, under the drive of the first driving member 61 and the second driving member 62 respectively, the rotating component 51 and the lifting component 52 can enter the open state, thereby opening the first aisle entrance and the second aisle entrance. The pusher device of the panel saw 1 pushes the plate 8 onto the workbench 2. After the plate 8 is in place, the pressing beam 4 descends, and the rotating component 51 and the lifting component 52 are converted from the open state to the closed state, closing the first aisle entrance and the second aisle entrance. When the plate 8 is in place and both the rotating component 51 and the lifting component 52 are in the closed state, the pressing beam 4, the workbench 2, the rotating component 51 and the lifting component 52 together form a closed space, ensuring that the sawdust generated during the sawing of the plate 8 does not escape from the closed space and spread to the external environment.

[0072] In this embodiment, by configuring the first driving member 61 to drive the rotation of the rotating component 51, the conversion between the closed state and the open state of the rotating component 51 is realized; by configuring the second driving member 62 to drive the lifting of the lifting component 52, the conversion between the closed state and the open state of the lifting component 52 is realized, which can simplify the structural design of the driving component 6 and ensure that the actions of the rotating component 51 and the lifting component 52 do not interfere with each other.

[0073] It can be understood that both the first driving member 61 and the second driving member 62 are controlled by a control system, and this control system is connected to the main control system of the panel saw 1. After the main control system pushes the plate 8 to the cutting position, it can send a control instruction to the control system, and then control the rotating component 51 and the lifting component 52 to convert between the open state and the closed state.

[0074] In this embodiment, through the cooperation of the first dust suction port 30 on the straightedge 3 and the second dust suction port 40 on the pressure beam 4, a directional air flow is formed to centrally adsorb wood chips and dust, improving the dust removal efficiency. The dust-proof component can be switched between a closed state and an open state by the driving component 6, closing the aisle to form a closed space, effectively preventing the leakage of wood chips and dust, and ensuring a clean operating environment. In addition, the pneumatic floating beads at some air outlets 21 reduce the friction between the board 8 and the workbench 2, and combined with the air outlet component 7 to guide the air flow direction, enhancing the flow efficiency of wood chips towards the dust suction port.

[0075] In another feasible solution, two rotating components 51 or two lifting components 52 can also be provided on both sides of the pressure beam 4 of the dust-proof component 5.

[0076] To improve the sealing effect of the rotating component 51, based on the above specific implementation manner, please refer to Figure 6 、 Figure 8 and Figure 9 , the panel saw 1 has two oppositely arranged columns 10, and the pressure beam 4 is located between the two columns 10;

[0077] The rotating component 51 includes a rotating shaft 511 and a plurality of first dust-proof strips 512;

[0078] The first driving member 61 includes a first cylinder 611 and a rotating crank 612;

[0079] Bearings 513 are provided at both ends of the rotating shaft 511, the bearings 513 are provided on the columns 10, the first end of the rotating crank 612 is connected to the end of the rotating shaft 511, and the second end of the rotating crank 612 is hinged to the output shaft of the first cylinder 611;

[0080] A first limiting structure 5110 is provided on the rotating shaft 511, the first dust-proof strip 512 has a mounting hole sleeving the rotating shaft 511, and a second limiting structure 5120 for clamping the first limiting structure 5110 is provided in the mounting hole. Under the action of the first driving member 61, the first dust-proof strip 512 rotates with the rotating shaft 511, so that the first dust-proof strip 512 closes or opens the first aisle opening.

[0081] The panel saw 1 has two columns 10 for supporting the panel saw 1, and the pressure beam 4 is located between the two columns 10. Bearings 513 are installed on the columns 10, and both ends of the rotating shaft 511 are installed and fixed on the columns 10 through the bearings 513. The rotating shaft 511 faces the front side of the pressure beam 4. The rotating assembly 51 is configured at the first crossing, and the first crossing is located in the exit area. The first dust-proof strip 512 is sleeved on the rotating shaft 511 and can rotate around the rotating shaft 511. A first limiting structure 5110 is provided on the rotating shaft 511, and a second limiting structure 5120 is provided inside the first dust-proof strip 512. With the cooperation of the first limiting structure 5110 and the second limiting structure 5120, the first dust-proof strip 512 is clamped and fixed, so that the first dust-proof strip 512 can rotate with the rotating shaft 511, enter the open state to open the first crossing. When the first driving member 61 is reset, the first dust-proof strip 512 can be reset by its own gravity and enter the closed state to close the first crossing.

[0082] In this embodiment, the first crossing is controlled by the rotating assembly 51, and the second crossing is controlled by the lifting assembly 52 to realize the independent opening and closing of both ends of the passage, adapting to the needs of different plates to enter and exit. The first driving member 61 and the second driving member 62 respectively control the rotating assembly 51 and the lifting assembly 52, reducing the mechanical complexity, reducing the failure rate, and at the same time improving the stability of the sealing action.

[0083] Further, the first dust-proof strip 512 includes an open snap ring 5121 and a dust-proof plate 5122, and ribs extending axially are provided on the outer periphery of the rotating shaft 511;

[0084] The open snap ring 5121 is provided with a first flange and a second flange extending radially outward in the circumferential direction. The open snap ring 5121 is sleeved on the rotating shaft 511, and the rib is located between the first flange and the second flange. The dust-proof plate 5122 is connected to the first flange.

[0085] Specifically, the first dust-proof strip 512 is installed on the rotating shaft 511. The rotating shaft 511 passes through the bearings 513 of the two columns 10 on both sides of the panel saw 1. Rotating cranks 612 are respectively provided at both ends of the rotating shaft 511, and these rotating cranks 612 are connected to the piston rods of the first cylinders 611. The first cylinders 611 are fixedly installed on the columns 10, and their telescopic movements can drive the rotating cranks 612 and the rotating shaft 511 to perform rotational movements in the bearings 513, thereby completing the opening and closing operations of the first dust-proof strip 512.

[0086] The rotating shaft 511 drives the first dust-proof strip 512 to rotate through the rib, and the first dust-proof strip 512 freely rotates relative to the rotating shaft 511 by its own weight. When the sheet 8 is loaded from the rear or the front, the pressing beam 4 rises, the first cylinder 611 extends the piston rod, drives the rotating crank 612 to rotate, and drives the rotating shaft 511 to rotate, so as to make the first dust-proof strip 512 open the first access opening to avoid the collision between the sheet 8 and the dust-proof strip. When the sheet 8 moves to the cutting position, the first dust-proof strip 512 closes. Due to the presence of the sheet 8 and the free rotation ability of the first dust-proof strip 512 relative to the rotating shaft 511, part of the first dust-proof strip 512 cannot return to the initial state (i.e., the vertically downward state), but naturally hangs on the upper surface of the sheet 8. During the process of the saw blade moving from right to left to cut the sheet 8, when the sawing-generated dust diffuses, due to the blockage of the first dust-proof strip 512 in front of the pressing beam 4, the dust can be effectively prevented from diffusing to the outside.

[0087] In this embodiment, the first cylinder 611 drives the rotating shaft 511 to rotate through the rotating crank 612, drives the first dust-proof strip 512 to quickly close or open the aisle, has a fast response speed and a remarkable sealing effect, and the first limiting structure 5110 on the rotating shaft 511 is clamped with the second limiting structure 5120 of the first dust-proof strip 512 to ensure the accurate position of the dust-proof strip and avoid misalignment caused by vibration.

[0088] In another feasible solution, to improve the sealing effect between the first dust-proof strip 512 and the sheet 8 and the surface of the workbench 2, and eliminate the gap between the part of the first dust-proof strip 512 hanging on the upper surface of the sheet 8 and the part hanging on the surface of the workbench 2. On the basis of the foregoing specific embodiment, the dust-proof plate 5122 is composed of a dust-proof outer shell and a dust-proof inner shell, and the first limiting structure 5110 and the second limiting structure 5120 are connected to each other through an elastic element. Specifically, the dust-proof inner shell is embedded in the dust-proof outer shell and can slide on the dust-proof outer shell. The elastic element can be a rubber rubber band or a spring 722 with relatively high durability. After the first cylinder 611 is reset, the first dust-proof strip 512 rotates by the gravity of the dust-proof outer shell and the dust-proof inner shell. The dust-proof inner shell is squeezed by the sheet 8 and automatically retracts into the dust-proof outer shell, and under the elastic force of the elastic element, it pushes the opening snap ring 5121 to continue to rotate, thereby driving the dust-proof outer shell and the dust-proof inner shell to move outward, so that the first dust-proof strip 512 placed on the sheet 8 can complete the reset operation in the vertical state, thus avoiding the problem of gaps between the first dust-proof strips 512.

[0089] Although the reset operation of the first dust-proof strip 512 in the vertical state is achieved through the dust-proof inner shell, the dust-proof outer shell, and the elastic element, during the actual application process, the dust-proof inner shell is likely to scratch the plate 8. To solve this technical problem, on the basis of the foregoing specific embodiment, balls are added to the bottom of the dust-proof inner shell to achieve rolling contact between the dust-proof inner shell and the plate 8, thereby avoiding the problem of damage to the plate 8.

[0090] In this embodiment, the opening snap ring 5121 cooperates with the rib of the rotating shaft 511 to achieve the convenient installation and replacement of the dust-proof plate 5122, reduce the maintenance cost. The dust-proof plate 5122 naturally hangs down by gravity, fits the surface of the plate or the workbench 2, eliminates the gap, and prevents dust from escaping from the edge.

[0091] In a preferred embodiment, please refer to Figures 10 to 13 , the above-mentioned lifting assembly 52 includes a moving plate 521 and a plurality of second dust-proof strips 522 slidably engaged with the moving plate 521. The plurality of second dust-proof strips 522 are arranged side by side and equidistantly along the length direction of the moving plate 521, and adjacent second dust-proof strips 522 are connected;

[0092] The second driving member 62 includes two second cylinders. The two second cylinders are respectively located at both ends of the moving plate 521. The second cylinders are fixed on the column 10, and the output shafts of the second cylinders are connected to the moving plate 521.

[0093] In this embodiment, the second dust-proof strip 522 is lifted and slid by the moving plate 521, automatically adjusts the height according to the thickness of the plate, closely fits the plate and the workbench 2, adapts to diverse processing requirements. The multiple second dust-proof strips 522 are arranged side by side and equidistantly, dispersing the pressing force, avoiding local wear, and prolonging the service life.

[0094] Further, the moving plate 521 includes a hanging plate 5211 and a plurality of guide blocks 5212. The guide blocks 5212 are equidistantly arranged on the hanging plate 5211. Vertical extending chutes 5212a are provided on both side surfaces of the guide blocks 5212. The second dust-proof strip 522 has a groove 522a for receiving the guide block 5212 and a third folded edge 522b for clamping the chute 5212a.

[0095] In this embodiment, the chute 5212a of the guide block 5212 cooperates with the third folded edge 522b of the second dust-proof strip 522 to ensure the vertical movement of the dust-proof strip during the lifting process, avoid tilting and jamming. The combined structure of the hanging plate 5211 and the guide block 5212 simplifies the processing and assembly, and improves the production efficiency.

[0096] In another feasible solution, to simplify the structure of the moving plate 521, the guide block 5212 is omitted. The moving plate 521 is a frame or plate-like member. The moving plate 521 is provided with sliding holes penetrating through both ends in its height direction. The second dust-proof strip 522 is suspended on the moving plate 521 through the sliding holes, and the head of the second dust-proof strip 522 is larger than the diameter of the sliding holes. Specifically, the moving plate 521 is arranged in a plate-like structure, which has a top surface, a bottom surface, and four side surfaces. The sliding passes through the bottom surface from the top surface. The second dust-proof strip 522 passes through the sliding holes and is clamped with the moving plate 521. When the second driving member 62 drives the moving plate 521 to rise, under the action of clamping, the second dust-proof strip 522 follows the moving plate 521 to rise. When the sheet 8 is pushed to the cutting position, the second driving member 62 drives the moving plate 521 to descend, and the second dust-proof strip 522 follows to descend. During the descent of the second dust-proof strip 522, the second dust-proof strip 522 located on the sheet 8 abuts against the surface of the sheet 8, and the remaining second dust-proof strips 522 abut against the workbench 2, thus sealing the second crossing.

[0097] As Figure 14 and Figure 15 shown, on the basis of the above specific implementation, along the extending direction of the saw kerf 20, a plurality of air outlet assemblies 7 are arranged side by side on both sides of the saw kerf 20. The workbench 2 has an air cavity and mounting holes communicated with the air cavity;

[0098] The air outlet assembly 7 includes an air duct assembly 71 and an elastic switch 72. The air duct assembly 71 has an air inlet, an air duct, and an air outlet that are communicated with each other. The air duct assembly 71 is arranged on the mounting hole, and the elastic switch 72 is arranged in the air duct assembly 71. When the elastic switch 72 is in a compressed state, the air outlet is communicated with the air duct. When the elastic switch 72 is in a relaxed state, the air outlet is closed.

[0099] In this embodiment, the elastic switch 72 automatically compresses or relaxes according to the gravity of the sheet 8 to control the air outlet to be conducted or closed, realizing an energy-saving mode of "air outlet when there is a plate and closed when there is no plate". Moreover, the air duct assembly 71 cooperates with the elastic switch 72 to accurately direct the air flow to the first dust suction port 30, avoiding the reduction of the dust removal efficiency caused by the dispersion of the air flow.

[0100] In some embodiments, the air duct assembly 71 includes an upper valve sleeve 711 and a lower valve sleeve 712. The lower valve sleeve 712 is embedded in the upper valve sleeve 711. The upper valve sleeve 711 is snap-connected to the workbench 2. The upper valve sleeve 711 has the air outlet. The outer periphery of the lower valve sleeve 712 is provided with a hollow structure, and the hollow structure is the air inlet. The elastic switch 72 is arranged in the lower valve sleeve 712;

[0101] The upper valve sleeve 711 is snap-connected to the workbench 2, and the upper valve sleeve 711 is snap-connected to the lower valve sleeve 712.

[0102] The upper valve sleeve 711 and the lower valve sleeve 712 are connected by snaps. The upper valve sleeve 711 is also connected to the workbench 2 by snaps. The outer periphery of the upper valve sleeve 711 is provided with snaps, and its inner side wall is provided with grooves. The inner side wall of the mounting hole of the workbench 2 is designed with a slot that is inserted and matched with the snap, and the outer peripheral wall of the lower valve sleeve 712 is provided with a hook that is snap-connected to the groove. Both the upper valve sleeve 711 and the lower valve sleeve 712 are in a cylindrical structure. One end of the upper valve sleeve 711 is designed to be open, and the end face of the other end is provided with an air outlet. The diameter of the air outlet is smaller than the inner diameter of the upper valve sleeve 711. The lower valve sleeve 712 is fitted with the upper valve sleeve 711. One end facing the air outlet is also designed to be open, and the end face of the other end can be a sealed plane or a corresponding hollow structure can be provided. The elastic switch 72 is arranged in the lower valve sleeve 712. The end of the elastic switch 72 abuts against the end face of the lower valve sleeve 712. The upper valve sleeve 711 and the lower valve sleeve 712 jointly define an air outlet cavity for accommodating the elastic switch 72. When no sheet material 8 is placed on the workbench 2, the elastic switch 72 is in a relaxed state. At this time, the elastic switch 72 can block the air outlet. When the elastic switch 72 is deformed by the gravity of the sheet material 8, the elastic switch 72 will contract, thereby opening the air outlet and realizing the discharge of air.

[0103] In addition, the upper valve sleeve 711 and the lower valve sleeve 712 can be manufactured by an injection molding one-piece forming process. In a preferred embodiment, nylon or polycarbonate is selected as the manufacturing material. Such a structure is particularly suitable for high-strength assembly requirements. Using recycled materials and directly injection molding through a mold on an injection molding machine can realize the recycling of recycled plastics.

[0104] In this embodiment, the upper valve sleeve 711 and the lower valve sleeve 712 are connected by snaps, which is convenient for disassembling and cleaning the dust accumulated in the air duct, preventing blockage from affecting the air outlet efficiency. At the same time, the nested valve sleeve design can reduce the gaps between components, ensure that the air flow is only discharged directionally from the air outlet, and improve the stability of the air pressure.

[0105] To improve the durability of the elastic switch 72, the elastic switch 72 includes a sphere 721 and a spring 722. The first end of the spring 722 is connected to the sphere 721, and the second end is connected to the bottom wall of the lower valve sleeve 712. The sphere 721 is embedded in the air outlet, and the diameter of the sphere 721 is larger than the diameter of the air outlet, so that a part of the sphere 721 protrudes outside the air outlet;

[0106] The inner diameter of the lower valve sleeve 712 is greater than the diameter of the sphere 721. The material of the sphere 721 can be selected from metal and plastic. In some embodiments, the sphere 721 can be a steel ball or a nylon ball. When a steel ball is used, the spring 722 is welded to the steel ball. When a nylon ball is used, the spring 722 and the nylon ball can be integrally designed by injection molding through a mold to improve the connection firmness between the nylon ball and the spring 722.

[0107] On the basis of the above specific implementation manner, the air outlet assembly 7 further includes a wind guide cover 73. The wind guide cover 73 is located above the air outlet. The wind guide cover 73 is connected to the elastic switch 72. The wind guide cover 73 has a chamber for receiving the upper valve sleeve 711. The wind guide cover 73 can slide up and down relative to the upper valve sleeve 711. One side of the wind guide cover 73 is provided with a wind guide outlet, and the wind guide outlet faces the first dust suction port 30. In some embodiments, the wind guide cover 73 is further provided with an arc-shaped wind guide surface for guiding the flow.

[0108] In this embodiment, the arc-shaped wind guide surface of the wind guide cover 73 concentrates the air flow at the air outlet and guides it to the first dust suction port 30, reducing the residue of wood chips on the surface of the workbench 2. The wind guide cover 73 can slide up and down to adapt to the thickness of the board, avoiding secondary dust generation caused by the air flow swirling back.
