Description

Technical Field

[0001] The embodiments of the present invention relate to the field of board sanding technology, specifically to a sanding device for the production of decorative boards. Background Technology

[0002] In the production and processing of decorative panels (such as solid wood panels, MDF, plywood, PVC decorative panels, etc.), the surface sanding process is one of the key steps determining product quality. This process removes burrs, scratches, glue residue, and unevenness defects from the panel surface, achieving the preset flatness and smoothness requirements, laying the foundation for subsequent coating, lamination, or splicing processes. However, this sanding process generates dust containing dirt and sawdust. If this dust is not properly controlled, it can not only pollute the production environment and affect the health of operators, but may also adhere to the sanded panel surface, increasing subsequent cleaning processes and reducing production efficiency.

[0003] Existing grinding equipment typically uses a dust collection hood to create a closed working space, along with corresponding dust removal facilities. However, to achieve continuous conveying of sheet metal, the dust collection hood needs to have both an input and output channel, which become the main pathways for dust overflow. Current methods to prevent dust overflow from these channels involve installing a flexible rubber strip at the outlet. When a sheet metal is conveyed, the strip is pushed to one side, ensuring the upper surface of the sheet metal adheres to the lower edge of the strip. At this point, the strip is tilted, and the two edges of the strip form a triangular gap with the end of the channel (this is especially noticeable when conveying thicker sheets). This gap increases the communication area between the inside and outside of the dust collection hood, increasing the probability of dust overflow. This is detrimental to maintaining a clean working environment and protecting the health of workers. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a grinding device for the production of decorative panels, which solves the technical problem that grinding devices in the related art are prone to overflowing dust and affecting the working environment when grinding panels.

[0005] According to one aspect, at least one embodiment of the present invention provides a sanding apparatus for the production of decorative panels, comprising:

[0006] The frame is equipped with a dust removal hood. The dust removal hood has a plate input channel and a plate output channel at both ends. The plate input channel is used to input the plate to be polished, and the plate output channel is used to output the polished plate. The top of the dust removal hood is connected to a dust discharge pipe.

[0007] A grinding and conveying assembly is disposed inside the dust removal hood and located between the plate input channel and the plate output channel. The grinding and conveying assembly is used to grind the plate to be ground that is input from the plate input channel and to output the ground plate through the plate output channel.

[0008] The dust prevention assembly has two components, which are respectively raised and lowered within the plate input channel and the plate output channel. The dust prevention assembly can be raised and lowered to close or open the plate input channel or the plate output channel.

[0009] For example, at least one embodiment of this disclosure provides a sanding apparatus for producing decorative panels, wherein the dust-proof component includes:

[0010] A baffle is provided in the plate input channel or the plate output channel, and the baffle can be moved down to abut against the inner bottom wall of the plate input channel or the plate output channel to close the plate input channel or the plate output channel;

[0011] The baffle can also move upwards to slide against the upper surface of the plate as the plate passes through.

[0012] For example, in at least one embodiment of this disclosure, a sanding apparatus for producing decorative panels is provided, wherein the dust-proof component further includes:

[0013] A drive block is disposed on the side of the baffle closer to the direction from which the plate body comes;

[0014] The lower part of the drive block has a drive ramp, the lower edge of the drive ramp is smoothly connected to the lower edge of the baffle, and the drive ramp is inclined to one side from bottom to top towards the plate body;

[0015] The driving ramp is used to guide the plate to move below the baffle, and with the pushing action of the plate, the baffle and the driving block move upward synchronously, thereby keeping the baffle in sliding contact with the upper surface of the plate.

[0016] For example, at least one embodiment of this disclosure provides a sanding apparatus for producing decorative panels.

[0017] The baffle is rectangular, and several baffles are arranged sequentially along the width direction of the plate input channel or the plate output channel.

[0018] For example, at least one embodiment of this disclosure provides a sanding apparatus for producing decorative panels.

[0019] The baffle has a strip-shaped protrusion and a strip-shaped groove on each of its two ends, and the strip-shaped protrusion on one of the baffles slides into the strip-shaped groove on the adjacent baffle.

[0020] For example, at least one embodiment of this disclosure provides a sanding apparatus for producing decorative panels, wherein the sanding conveying assembly includes:

[0021] Two rotating rollers are arranged in parallel within the dust removal hood.

[0022] A conveyor belt is fitted around the outer periphery of the two rotating rollers. The conveyor belt is used to receive the plate on the plate input channel and transport the polished plate to the plate output channel.

[0023] The mounting frame is lifted and positioned above the conveyor belt;

[0024] A pressure roller is rotatably mounted on the mounting frame. The pressure roller is arranged transversely along the conveyor belt. The pressure roller and the conveyor belt are respectively used to act on the upper and lower surfaces of the plate.

[0025] A grinding roller is rotatably mounted on the mounting frame. The grinding roller is located on the side of the pressure roller and is used to grind the upper surface of the plate.

[0026] For example, a sanding apparatus for producing decorative panels provided in at least one embodiment of this disclosure further includes:

[0027] An air-blowing cleaning assembly is provided on the mounting bracket. The air-blowing cleaning assembly is used to blow air onto the surface of the grinding roller to remove dust from the surface of the grinding roller.

[0028] For example, at least one embodiment of this disclosure provides a sanding apparatus for producing decorative panels, wherein the air-blowing cleaning component includes:

[0029] A tube body is disposed on the mounting bracket, the tube body is disposed along the axial direction of the grinding roller, and is located above the grinding roller;

[0030] The tube body has several air holes spaced apart.

[0031] For example, at least one embodiment of this disclosure provides a sanding apparatus for producing decorative panels.

[0032] An air inlet pipe is also provided through the dust removal hood, and the outlet end of the air inlet pipe is connected to the pipe body.

[0033] For example, a sanding apparatus for producing decorative panels provided in at least one embodiment of this disclosure further includes:

[0034] An input platform is mounted on the frame, and the conveying surface of the input platform is coplanar with the inner bottom wall of the plate input channel;

[0035] An output platform is mounted on the frame, and the conveying surface of the output platform is coplanar with the inner bottom wall of the plate output channel.

[0036] The beneficial effects of the embodiments of the present invention are as follows:

[0037] In this invention, the frame provides a fixed installation base for the dust collector hood. The synergy of the dust collector hood, exhaust pipe, and exhaust fan achieves efficient dust collection: the dust collector hood confines the grinding action within a closed space, preventing dust from directly spreading to the external environment; after the exhaust fan starts, it creates a negative pressure within the closed space, which actively draws the dust generated during grinding into the exhaust pipe, improving dust collection efficiency and reducing dust residue inside the dust collector hood. Simultaneously, the exhaust pipe connects to an external dust filter device, preventing direct dust discharge and environmental pollution, thus meeting environmental protection requirements.

[0038] The coordination of anti-dust overflow components and channels solves the dust overflow problem: The plate input channel and plate output channel are necessary openings for plate passage. In existing technologies, these openings often cause dust to overflow from the dust collector hood. In this solution, two anti-dust overflow components are respectively installed in the two channels. Without affecting plate passage, by reducing the gaps between the plate and the plate input and output channels, the probability of dust overflow is reduced, further improving the dust removal effect, improving the quality of the working environment around the device, and reducing the impact of dust on the health of operators.

[0039] The grinding and conveying assembly simultaneously grinds and conveys the board inside the dust removal hood. The dust generated during grinding can be immediately extracted by the exhaust fan, preventing dust from adhering to the surface of the ground board and reducing subsequent board cleaning processes. At the same time, the process of the board entering and being conveyed out is continuous, without the need to transfer the board in the middle, ensuring the continuity of the grinding operation and improving production efficiency.

[0040] The components work together to form a complete functional system: the support of the frame provides a foundation for the stable operation of each component, the enclosed dust collection hood provides space for dust collection, the grinding and conveying components realize the core grinding and conveying functions, the dust exhaust pipe and the exhaust fan complete the dust extraction, and the dust overflow prevention components reduce dust overflow. The components work together to solve the problem in the existing technology that dust easily overflows and affects the external environment when grinding the plate. Attached Figure Description

Detailed Implementation

[0055] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0056] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0060] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0061] like Figures 1-12 As shown, a sanding device for producing decorative panels according to an embodiment of the present invention is illustrated, including a frame 1, a dust removal hood 2, a sanding conveyor assembly 3, a dust discharge pipe 23, an exhaust fan 24, and a dust prevention assembly 4. (Dust as referred to herein includes dust, sawdust, and mixtures thereof).

[0062] The frame 1 serves as the supporting foundation for the entire grinding device, and its structure is adapted to the installation requirements of each component, ensuring that each component maintains relative positional stability during operation. The dust collector hood 2 is fixedly installed on the frame 1, and its interior forms a closed space to accommodate the grinding action. Along the conveying direction of the plate to be ground, the two end side walls of the dust collector hood 2 have a plate input channel 21 and a plate output channel 22, respectively, with their central axes extending in the same horizontal direction to ensure that the plate can pass smoothly through the dust collector hood 2 horizontally. To facilitate maintenance of the internal components of the dust collector hood 2, an inspection door is provided on the side wall of the dust collector hood 2. The inspection door is rotatably connected to the side wall of the dust collector hood 2 via hinges, and a sealing element (such as a sealing strip) is provided between the inspection door and the side wall of the dust collector hood 2 to ensure that the interior of the dust collector hood 2 remains closed when the inspection door is closed.

[0063] The grinding and conveying assembly 3 is located in the bottom area inside the dust removal hood 2 and is arranged along the conveying direction of the plate. The starting end of the grinding and conveying assembly 3 corresponds to the inner port of the plate input channel 21, and the ending end corresponds to the inner port of the plate output channel 22. The grinding and conveying assembly 3 includes a conveying structure and a grinding structure. The conveying structure and the grinding structure are linked to ensure that the grinding action is completed synchronously during the conveying of the plate.

[0064] One end of the dust exhaust pipe 23 is connected to the top of the dust removal hood 2, with the connection point located in the area above the grinding conveying assembly 3 on the top of the dust removal hood 2. The other end of the dust exhaust pipe 23 is connected to an external dust removal filter device to filter the extracted dust. The exhaust fan 24 is fixedly installed inside the cavity of the dust exhaust pipe 23, located at the end of the dust exhaust pipe 23 near the dust removal hood 2. The air inlet of the exhaust fan 24 faces the inside of the dust removal hood 2, and the air outlet faces the end of the dust exhaust pipe 23 connected to the external dust removal filter device.

[0065] There are two dust prevention components 4. One dust prevention component 4 is installed on the inner wall of the plate input channel 21 along the width direction of the channel, and the other dust prevention component 4 is installed on the inner wall of the plate output channel 22 along the width direction of the channel.

[0066] The working process of the polishing device is as follows: The exhaust fan 24 is started, and the exhaust fan 24 draws air into the dust collection hood 2 through the dust discharge pipe 23, so that the dust collection hood 2 is negatively pressured; the plate to be polished is pushed into the dust collection hood 2 from the plate input channel 21. When the plate passes through the plate input channel 21, the anti-overflow dust component 4 reduces the probability of dust overflow by reducing the gap between the plate 8 and the inner walls of the plate input channel 21. Air enters into the dust collection hood 2 through this gap (the gap between the plate 8 and the inner walls of the plate input channel 21) to achieve gas circulation. Since the gap is for air intake, the possibility of dust overflow is further reduced. After the grinding plate enters the dust collection hood 2, it falls onto the conveying structure of the grinding conveying assembly 3. The drive of the grinding conveying assembly 3 is activated, causing the conveying structure to rotate and the plate to move along the conveying direction. At the same time, the drive drives the grinding structure to rotate, grinding the surface of the plate during the movement. The dust generated during grinding is drawn into the dust discharge pipe 23 along with the air by the exhaust fan 24 and is then transported to the external dust collection and filtration device (such as a dust collector bag) through the dust discharge pipe 23. The ground plate continues to move with the conveying structure and is sent out of the dust collection hood 2 through the plate output channel 22. When the plate passes through the plate output channel 22, the anti-overflow dust assembly 4 in the channel also reduces the probability of dust overflow by reducing the gap between the plate 8 and the inner walls of the plate output channel 22. Air enters the dust collection hood 2 through this gap (the gap between the plate 8 and the inner walls of the plate output channel 22) to achieve gas circulation. Since the gap is for air intake, the possibility of dust overflow is further reduced.

[0067] In this embodiment, the frame 1 provides a fixed installation base for the dust collector hood 2. The dust collector hood 2, the dust exhaust pipe 23, and the exhaust fan 24 work together to achieve efficient dust collection: the dust collector hood 2 confines the grinding action within a closed space, preventing dust from directly spreading to the external environment; after the exhaust fan 24 is activated, it creates a negative pressure within the closed space, which actively draws the dust generated during grinding into the dust exhaust pipe 23, improving dust collection efficiency and reducing dust residue inside the dust collector hood 2. Simultaneously, the dust exhaust pipe 23 connects to an external dust filter device, preventing direct dust discharge and environmental pollution, thus meeting environmental protection requirements.

[0068] The dust overflow prevention component 4, in conjunction with the channels, solves the dust overflow problem: The plate input channel 21 and plate output channel 22 are necessary openings for the plate to pass through. In existing technologies, these openings often cause dust to overflow from the dust collector hood. In this solution, two dust overflow prevention components 4 are respectively installed in the two channels. Without affecting the passage of the plate, by reducing the gap between the plate 8 and the plate input channel 21 and plate output channel 22, the probability of dust overflow is reduced, further improving the dust removal effect, improving the quality of the working environment around the device, and reducing the impact of dust on the health of operators.

[0069] The grinding and conveying assembly 3 simultaneously grinds and conveys the board inside the dust removal hood 2. The dust generated during grinding can be immediately extracted by the exhaust fan 24, preventing dust from adhering to the surface of the ground board and reducing subsequent board cleaning processes. At the same time, the process of the board entering and being conveyed out is continuous, without the need to transfer the board in the middle, ensuring the continuity of the grinding operation and improving production efficiency.

[0070] The components work together to form a complete functional system: the support of the frame 1 provides a foundation for the stable operation of each component, the enclosure of the dust removal hood 2 provides space for dust collection, the grinding and conveying component 3 realizes the core grinding and conveying functions, the dust exhaust pipe 23 and the exhaust fan 24 complete the dust extraction, and the dust overflow prevention component 4 reduces dust overflow. The components work together to solve the problem in the prior art that when the grinding device grinds the plate 8, dust easily overflows and affects the external environment.

[0071] Furthermore, refer to Figure 1 and Figure 5 As shown, the dust prevention component 4 includes a baffle 41. The upper inner walls of both the plate input channel 21 and the plate output channel 22 are vertically oriented with grooves. The baffle 41 slides within these grooves, with its lower edge extending beyond the grooves into the plate input channel 21 and the plate output channel 22. The baffle 41 slides up and down along the grooves to achieve lifting and lowering. Since the weight of the baffle 41 is greater than the sliding friction between it and the grooves, without external force, the baffle 41 falls naturally under gravity, its lower edge fitting against the lower wall of the channel, thus sealing the channel. When the plate enters from the plate input channel 21 or exits from the plate output channel 22, the front end of the plate contacts the baffle 41 and applies an upward force, pushing the baffle 41 to rise along the slide. At this time, the lower edge of the baffle 41 is in contact with the upper surface of the plate. During the continuous movement of the plate, the baffle 41 always remains in contact with the upper surface of the plate until the plate has completely passed through the channel. The baffle 41 falls back to the initial position under the action of gravity and re-closes the channel.

[0072] In this embodiment, the lifting structure of the baffle 41 is combined with gravity drive, enabling automatic opening and closing of the channel without an additional power source. The function is achieved through the inherent characteristics of the mechanical structure. Simultaneously, the baffle 41 automatically adjusts its rising height according to the thickness of the plate 8, ensuring its lower edge remains in contact with the plate surface. This provides an effective seal for plates 8 of varying thicknesses, enhancing the versatility of the dust prevention component 4. After the plate 8 passes through, the baffle 41 falls back to close the channel, reducing the possibility of dust overflow.

[0073] Furthermore, refer to Figure 5 and Figure 12 As shown, the dust prevention assembly 4 also includes a drive block 42, which is fixed to the side of the baffle 41 closest to the direction from which the plate comes, and its length is the same as that of the baffle 41 (the length is the distance between the left and right ends of the baffle 41 in the horizontal direction). A drive ramp 421 is formed at the lower part of the drive block 42, which extends downwards from the side closest to the direction from which the plate comes to the other side, with its lower edge smoothly connected to the lower edge of the baffle 41, and its upper edge close to the side closest to the direction from which the plate comes to the. When the plate moves into the channel, the front end of the plate first contacts the drive ramp 421. As the plate continues to move forward, it generates an upward component force on the drive ramp 421, and the drive block 42 drives the baffle 41 to rise along the slide groove until the lower edge of the baffle 41 passes over the upper surface of the plate and fits against it.

[0074] In this embodiment, the driving ramp 421 of the driving block 42 converts the horizontal thrust of the plate into the upward force of the baffle 41. The ramp guides the baffle 41 to rise smoothly, ensuring the smooth conveying of the plate 8. The smooth connection between the driving ramp 421 and the lower edge of the baffle 41 allows the front end of the plate to smoothly transition to the area below the baffle 41.

[0075] Furthermore, refer to Figure 3 , Figure 5 and Figure 12 As shown, the baffle 41 is a rectangular structure, with several arranged side-by-side along the horizontal width of the plate input channel 21 or the plate output channel 22, with a small gap reserved between adjacent baffles 41. Each baffle 41 slides within a groove in its corresponding channel, and each moves up and down independently along the groove without interfering with the others. When the width of the plate 8 is less than the width of the channel (refer to...), Figure 6 and Figure 7 As shown), the plate 8 pushes only the baffles 41 within the corresponding width range to rise through the channel, while the remaining baffles 41 remain in contact with the lower wall of the channel; when the width of the plate is the same as the width of the channel, all baffles 41 are pushed to rise, and their lower edges press together on the upper surface of the plate to form a complete seal.

[0076] In this embodiment, several parallel baffles 41 can be partially raised and lowered according to the width of the plate. When the width of the plate 8 is less than the width of the channel, the unpushed baffles 41 can still seal the remaining area of ​​the channel, reducing the gap between the plate and the inner wall of the channel and reducing the risk of dust overflowing from areas where the plate does not pass. The segmented design makes the sealing more targeted, improving the dust prevention effect when plates of different widths pass through. At the same time, the segmented design reduces the weight of a single baffle 41, further reducing the resistance when the plate 8 pushes the baffle 41 upward, reducing power consumption during plate transportation, reducing wear between the plate and the baffle 41, and extending the service life of the components. In addition, a single baffle 41 can be replaced individually when damaged, without the need for overall replacement, reducing maintenance costs.

[0077] Preferably, such as Figure 7 As shown, the upper end of the baffle 41 is connected to a pull member 7 (which can be a spring, a tension rope, etc., with one end of the pull member 7 connected to the slide wall and the other end connected to the upper end of the baffle 41). Under the pulling force of the pull member 7, when the lower edge of the baffle 41 contacts the inner wall below the plate input channel 21 or the plate output channel 22, the pulling force of the pull member 7 is equal to the weight of the baffle 41 (ensuring that the baffle 41 can easily rise and open under the drive of the front end of the plate, and reducing the wear on the drive inclined surface 421).

[0078] Furthermore, as a specific implementation method, such as Figure 8 and Figure 7 As shown, the chute is a through groove, that is, a strip-shaped sliding hole 43 (penetrating the upper side wall of the plate input channel 21 or the plate output channel 22). The baffle 41 is vertically set and penetrates the strip-shaped sliding hole 43. The upper end of the baffle 41 is connected to the pull member 7, and the lower edge of the baffle 41 is located in the plate input channel 21 or the plate output channel 22.

[0079] Furthermore, refer to Figure 11 and Figure 12 As shown, the left end face of the baffle 41 has a strip-shaped protrusion 411 along its length (the baffle 41 is vertically slidable and rectangular, i.e., it has upper and lower ends and left and right ends), and the right end face has a strip-shaped groove 412 along its length. The cross-sectional shape of the strip-shaped protrusion 411 matches the cross-sectional shape of the strip-shaped groove 412, such as a dovetail shape, and the length of the strip-shaped protrusion 411 is the same as the length of the baffle 41. When several baffles 41 are arranged side by side, the strip-shaped protrusion 411 of one baffle 41 is embedded in the strip-shaped groove 412 of the adjacent baffle 41, forming a sliding fit. The strip-shaped protrusion 411 can slide freely along the vertical direction of the strip-shaped groove 412, and the gap between the two is small.

[0080] In this embodiment, the cooperation between the strip-shaped protrusion 411 and the strip-shaped groove 412 improves the sealing between adjacent baffles 41 and reduces the possibility of dust overflowing from the gaps between the baffles 41. At the same time, it guides the lifting and lowering of the baffles 41, preventing the baffles 41 from shifting or tilting during the lifting and lowering process, improving the stability of the plate conveying during the grinding process, and extending the service life.

[0081] Furthermore, refer to Figure 4 As shown, the grinding and conveying assembly 3 includes a rotating roller 31, a conveyor belt 32, a mounting frame 33, a pressure roller 34, and a grinding roller 35. The rotating roller 31 is horizontally rotatably mounted at the bottom of the dust collector hood 2. Two rotating rollers 31 are spaced apart along the conveying direction of the plate, and their ends are connected to the inner wall of the dust collector hood 2 via bearing seats. One of the rotating rollers 31 is connected to a drive motor. The conveyor belt 32 is fitted over the two rotating rollers 31, and its conveying surface is coplanar with the lower walls of the plate input channel 21 and the plate output channel 22. The mounting frame 33 is located above the conveyor belt 32, and vertical guide rails are provided on both sides of the inner wall of the dust collector hood 2. The two ends of the mounting frame 33 are slidably connected to the guide rails. The pressure roller 34 and the grinding roller 35 are both horizontally rotatably mounted on the mounting frame 33. The central axes of both are perpendicular to the conveying direction of the conveyor belt 32, and the surface of the grinding roller 35 is provided with a grinding layer such as sandpaper or a grinding wheel. During operation, the lifting drive unit drives the mounting frame 33 to descend, bringing the pressure roller 34 and the grinding roller 35 closer to the conveyor belt 32. The plate is moved by the conveyor belt 32, and after being pressed by the pressure roller 34, it enters the area below the grinding roller 35. The grinding roller 35 rotates to grind the upper surface of the plate, and the ground plate is sent out from the plate output channel 22 along with the conveyor belt 32.

[0082] Preferably, multiple sets of grinding rollers 35 are arranged sequentially along the conveying direction; or the surface of the conveyor belt 32 is provided with anti-slip texture to enhance the friction between it and the plate. As a specific implementation, for example... Figure 4 As shown, in the plate conveying direction, there are three sets of pressure rollers 34 spaced apart. One set is located above the middle of the conveyor belt 32, and the other two sets are close to the plate input channel 21 and the plate output channel 22, respectively. There are two sets of grinding rollers 35. The two sets of grinding rollers 35 are located between two adjacent sets of pressure rollers 34. The two sets of grinding rollers 35 rotate in opposite directions, and the movement direction of the outer peripheral wall above the grinding rollers 35 is towards the middle (that is, between the two sets of grinding rollers 35, at the middle pressure roller 34). The dust discharge pipe 23 is located at the top middle position of the dust removal hood 2, that is, above the middle pressure roller 34.

[0083] In this embodiment, the rotating roller 31 and the conveyor belt 32 cooperate to achieve continuous conveying of the board. The pressure roller 34 presses the board tightly onto the conveyor belt 32, preventing the board from shifting or vibrating due to the friction of the grinding roller 35 during the grinding process. This ensures the stability of the contact between the grinding roller 35 and the board surface and improves the grinding accuracy. The lifting and lowering setting of the mounting frame 33 allows the distance between the pressure roller 34 and the grinding roller 35 and the conveyor belt 32 to be adjustable, adapting to the grinding needs of decorative boards of different thicknesses.

[0084] Furthermore, refer to Figure 4 and Figure 10 As shown, the polishing device also includes an air-blowing cleaning component 5, which is fixed on the mounting bracket 33 and located on one side above the polishing roller 35. It is connected to an external air source through a pipeline, and the air outlet direction is towards the outer circumferential surface of the polishing roller 35. When the polishing roller 35 rotates the polishing plate, the air-blowing cleaning component 5 continuously sprays air to blow away the dust adhering to the surface of the polishing roller 35. The blown-away dust is sucked into the dust exhaust pipe 23 under the negative pressure generated by the exhaust fan 24, preventing it from drifting in the dust removal hood 2 (the movement direction of the outer circumferential wall above the polishing roller 35 is set towards the middle, which can guide the blown-away dust to move towards the middle, making it easier to suck away the dust through the dust exhaust pipe 23), and can ensure the cleanliness of the surface of the polishing roller 35, thereby maintaining the polishing effect and polishing efficiency.

[0085] In this embodiment, the air-blowing cleaning component 5 can remove dust adhering to the surface of the grinding roller 35 in real time, thus preventing dust accumulation on the surface of the grinding roller 35 from reducing its grinding effect and efficiency. At the same time, the blown-off dust is promptly drawn into the dust exhaust pipe 23, reducing the dust concentration in the dust removal hood 2, lowering the probability of dust re-adhering to the surface of the ground board, and reducing the workload of subsequent board cleaning processes.

[0086] Furthermore, refer to Figure 4 and Figure 10 As shown, the air-blowing cleaning assembly 5 includes a tube 51, which is fixed to the mounting bracket 33 by a support. The tube 51's length direction is aligned with the length direction of the polishing roller 35 and is located above the polishing roller 35. Several air-blowing holes 52 are spaced apart along the length of the side wall of the tube 51 near the polishing roller 35, with the axis of each air-blowing hole 52 facing the outer circumferential surface of the polishing roller 35. The tube 51 is closed at both ends, with an air inlet on the middle side wall, which is connected to an external air source via a pipe. During operation, gas enters the tube 51 through the air inlet, is distributed within the internal cavity, and is simultaneously ejected through the air-blowing holes 52 to different positions on the surface of the polishing roller 35, forming multiple airflows covering the entire length of the polishing roller 35.

[0087] In this embodiment, the tube body 51 is arranged along the length of the polishing roller 35, and is equipped with several evenly spaced air holes 52, so that the airflow can cover the entire surface of the polishing roller 35, ensuring that dust in all areas of the polishing roller 35 can be effectively removed, avoiding cleaning blind spots caused by single-point or localized air blowing. The multi-hole design achieves comprehensive cleaning and improves the cleanliness of the surface of the polishing roller 35.

[0088] Furthermore, refer to Figure 1 and Figure 4 As shown, an air inlet pipe 25 is installed through the side wall of the dust collector hood 2. The end of the air inlet pipe 25 located outside the dust collector hood 2 is connected to an air source, and the end located inside the dust collector hood 2 is connected to the air inlet of the pipe body 51. When the grinding device is working, the air source continuously supplies gas to the pipe body 51 through the air inlet pipe 25.

[0089] In this embodiment, the air inlet pipe 25 directly introduces the air source from outside the dust removal hood 2, avoiding the problem of dust being sucked into the pipe body 51 caused by taking air from inside the dust removal hood 2, ensuring the cleanliness of the air source of the blowing cleaning component 5, and reducing the probability of the blowing hole 52 being blocked by dust or impurities.

[0090] In another implementation, the end of the air inlet pipe 25 located outside the dust collector hood 2 is an open end, or a filter screen is installed. The exhaust fan 24 itself draws air into the dust collector hood 2 to generate negative pressure, guiding the external airflow through the air inlet pipe 25 into the pipe body 51, and then into the dust collector hood 2 through the air blowing hole 52, thereby realizing air circulation. This not only removes dust, but also cleans the surface of the grinding roller 35 with air blowing. This method can be achieved without adding any other structures.

[0091] Preferably, a high-pressure air source or a blower is connected to one end of the air inlet pipe 25 outside the dust removal hood 2, so that it can work together with the exhaust fan 24 to achieve gas circulation, discharge dust and clean the polishing roller 35.

[0092] Furthermore, such as Figure 4 As shown, the grinding device also includes an input platform 61 and an output platform 62. The input platform 61 is fixedly installed on the frame 1 near the side of the plate input channel 21, and its top surface is a horizontal conveying surface, which is at the same level as the lower inner wall surface of the plate input channel 21. The output platform 62 is fixedly installed on the frame 1 near the side of the plate output channel 22, and its top surface is a horizontal conveying surface, which is at the same level as the lower inner wall surface of the plate output channel 22. The plate to be ground is conveyed to the inlet of the plate input channel 21 through the conveying surface of the input platform 61 and pushed into the dust collection hood 2; the ground plate is sent out from the plate output channel 22 and falls into the conveying surface of the output platform 62, and is then conveyed by the output platform 62 to the next process.

[0093] In this embodiment, the coplanarity of the input platform 61 and the plate input channel 21 provides a smooth transition for the plate entering the channel, avoiding the front end of the plate from tilting or getting stuck due to height differences. This ensures that the plate can smoothly enter the grinding conveying assembly 3 inside the dust removal hood 2, reducing collision and wear between the plate and the channel inlet. The coplanarity of the output platform 62 and the plate output channel 22 provides stable support for the ground plate.

[0094] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
