Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of curtain wall panel processing equipment technology, and more specifically, to a curtain wall panel grinding device. Background Technology

[0002] In the field of architectural decoration, imitation stone curtain wall panels are widely used because they combine the aesthetics of natural stone with cost advantages. To achieve the ideal decorative effect, the curtain wall panels need to be polished evenly and cleanly while retaining a rough, stone-like surface.

[0003] However, current polishing work faces several challenges. Firstly, the imitation stone curtain wall panels are large in area and have rough surfaces, requiring large polishing discs. During polishing, the polishing effect differs significantly between the center and edges of the disc. The center, due to concentrated force, achieves better polishing results, but also suffers greater wear and tear, leading to frequent disc replacements and increased costs and time. Conversely, the edges, with their more dispersed force distribution, produce less effective polishing, failing to meet overall uniformity requirements.

[0004] On the other hand, the pressure exerted vertically by the grinding disc on the imitation stone curtain wall panel during polishing is insufficient. This results in inadequate polishing force, making it difficult to effectively polish rough surfaces and ensuring the cleanliness of the curtain wall panel surface, thus affecting the overall decorative quality of the imitation stone curtain wall panel. Therefore, there is an urgent need to develop a curtain wall panel polishing device to solve the problems of uneven polishing, uneven wear of the grinding disc, and insufficient pressure. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a curtain wall panel grinding device, which solves the technical problems of insufficient grinding pressure and uneven wear of grinding discs for large-sized imitation stone curtain wall panels in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides a curtain wall panel grinding apparatus, comprising:

[0007] A disc body, the disc body having axial and radial dimensions;

[0008] A polishing brush, comprising several brushes, having a sliding part and a brush part, wherein the sliding part is slidably disposed within the disc body along an axial direction parallel to the disc body, and the brush part is located outside the disc body for polishing curtain wall panels;

[0009] A sliding block is slidably disposed on the disc body along the radial direction of the disc body, and is capable of centrifugal sliding after the disc body rotates;

[0010] The throwing block has a first pushing slope, and the sliding part has a first pushed slope. The first pushing slope and the first pushed slope abut against each other. The throwing block can push the grinding brush to slide and approach the curtain wall panel through the first pushing slope and the first pushed slope.

[0011] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, which further includes:

[0012] A first elastic element, one end of which acts on the throwing block and the other end of which acts on the disc body, is used to provide a force for the centripetal movement of the throwing block;

[0013] The second elastic element, with one end acting on the sliding part and the other end acting on the disc body, is used to provide the grinding brush with force away from the curtain wall panel.

[0014] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, wherein the sliding part has a receiving space for accommodating the grinding brush, the grinding brush also has a sliding shaft, the sliding shaft is slidably disposed in the receiving space along a parallel axis to the disc body, the brush part is an elastic steel wire and is mounted on the sliding shaft, the brush part is inclined relative to the receiving space, and under its own elastic action, it abuts against the inner wall of the receiving space and the tilt angle is restricted by the lower end of the receiving space. After the sliding shaft slides downward toward the curtain wall panel, it can drive the brush part to move in the receiving space and change the tilt angle of the brush part relative to the curtain wall panel.

[0015] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, wherein the brush extends from both sides of the sliding axis.

[0016] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, which further includes:

[0017] The third elastic element has one end acting on the sliding shaft and the other end acting on the sliding part, and is used to provide a force for the sliding shaft to move closer to the swing block.

[0018] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, wherein the disc body has a centrifugal limiting part, which is located on the side of the throwing block away from the center of the disc body, and is used to limit the position of the throwing block to centrifugal sliding.

[0019] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, which further includes:

[0020] A push rod, the lower end of which is connected to the sliding shaft, and the upper end of which has a second pushed inclined surface;

[0021] The secondary throwing block is slidably disposed on the throwing block along the radial direction of the disc body. It has a second pushing inclined surface, which abuts against the second pushed inclined surface. The secondary throwing block can slide centrifugally relative to the throwing block after the throwing block abuts against the centrifugal limiting part. After centrifugal sliding, it can push the pushing rod to move through the second pushing inclined surface and the second pushed inclined surface.

[0022] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, which further includes:

[0023] The fourth elastic element has one end acting on the secondary throwing block and the other end acting on the throwing block, and is used to provide a force for the centripetal movement of the secondary throwing block.

[0024] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device, wherein the brush is replaceably disposed on the sliding shaft.

[0025] For example, at least one embodiment of this disclosure provides a curtain wall panel grinding device in which the grinding brushes are arranged in a group along the radial direction of the disc body, and several groups of grinding brushes are arranged circumferentially around the axial direction of the disc body. The throwing blocks are also arranged in several circumferentially. One of the throwing blocks can push a group of grinding brushes to slide and approach the curtain wall panel through the first pushing inclined surface and the first pushed inclined surface.

[0026] The beneficial effects of the embodiments disclosed herein are as follows:

[0027] In this disclosure, the grinding brush is automatically pushed to slide by the centrifugal force when the disc rotates, so that the grinding brush applies a more uniform grinding pressure to the curtain wall panel at different positions on the disc. This effectively solves the problem of obvious differences in grinding effect between the center and the edge of the traditional grinding disc, and ensures uniform grinding of the curtain wall panel surface.

[0028] Because the grinding brush can automatically adjust the contact pressure with the curtain wall panel according to the force on different parts of the disc, it avoids the problem of excessive wear due to concentrated force at the center of the grinding disc, thus extending the service life of the grinding brush and reducing the cost and time of replacing grinding parts.

[0043] like Figures 1-6The diagram illustrates a curtain wall panel grinding device according to an embodiment of the present disclosure, comprising a disc body 100, grinding brushes 200, a swivel block 300, a first elastic element 410, and a second elastic element 420. The disc body 100 has an axial direction and a radial direction. The grinding brushes 200 are multiple in number, each having a sliding part 210 and a brush part 220. The sliding part 210 is slidably disposed within the disc body 100 along the axial direction parallel to the disc body 100, while the brush part 220 is located outside the disc body 100 for grinding the curtain wall panel. The swivel block 300 is slidably disposed on the disc body 100 along the radial direction of the disc body 100 and can slide centrifugally after the disc body 100 rotates. The swivel block 300 has a first pushing inclined surface 310, and the sliding part 210 has a first pushed inclined surface 211. The first pushing inclined surface 310 abuts against the first pushed inclined surface 211, and the swivel block 300 can push the grinding brushes 200 to slide and approach the curtain wall panel through the first pushing inclined surface 310 and the first pushed inclined surface 211. The first elastic element 410 acts on the throwing block 300 at one end and on the disc body 100 at the other end, and is used to provide the force for the throwing block 300 to move centripetally; the second elastic element 420 acts on the sliding part 210 at one end and on the disc body 100 at the other end, and is used to provide the force for the grinding brush 200 to move away from the curtain wall panel.

[0044] For example, the disc body 100 is generally disc-shaped with clearly defined axial and radial directions. A mounting hole or mounting shaft is provided at the center of the disc body 100 for connection to the output shaft of the drive motor, thereby enabling the disc body 100 to rotate. Inside the disc body 100, several radially arranged grooves are provided to accommodate the sliding part 210 of the grinding brush 200, allowing the grinding brush 200 to slide along the axial direction of the disc body 100. Corresponding grooves or tracks are also provided at the edges of the disc body 100 for mounting the swivel block 300, ensuring that the swivel block 300 can slide radially when the disc body 100 rotates. The disc body 100, as the basic component of the entire grinding device, provides a carrier for the installation and movement of the grinding brush 200 and the swivel block 300. Connected to the drive motor, the disc body 100 rotates at high speed under the motor's drive, thereby driving the grinding brush 200 and the swivel block 300 to move together, realizing the grinding operation on the curtain wall panel.

[0045] The polishing brush 200 consists of two parts: a sliding part 210 and a brush part 220. The sliding part 210 is shaped to fit a groove within the disc body 100, allowing it to slide smoothly within the groove. A first pushed inclined surface 211 is provided on the side of the sliding part 210 near the throwing block 300, for contacting the first pushing inclined surface 310 of the throwing block 300. The brush part 220 is installed at the end of the sliding part 210 extending out of the disc body 100. The brush part 220 is composed of wear-resistant bristles. The material of the bristles can be selected according to the material of the curtain wall panel and the polishing requirements. For example, steel wire bristles can be used for curtain wall panels with higher hardness, while nylon bristles can be used for relatively softer curtain wall panels. The shape and size design of the brush part 220 must ensure effective coverage of the curtain wall panel surface for comprehensive polishing.

[0046] The polishing brush 200 is the component that directly contacts and polishes the curtain wall panel. During the rotation of the disc 100, the swivel block 300, under centrifugal force, pushes the sliding part 210 of the polishing brush 200 along the axial direction of the disc 100 via the first pushing inclined surface 310 and the first pushed inclined surface 211, bringing the brush part 220 closer to the curtain wall panel and thus polishing its surface. Simultaneously, the force provided by the second elastic element 420 can, to some extent, compensate for the real-time wear of the polishing brush 220 during the polishing process, ensuring that the polishing brush 220 always maintains appropriate contact pressure with the curtain wall panel surface, thus maintaining a stable polishing effect.

[0047] The swivel block 300 is made of a heavy metal material to ensure that it can generate sufficient centrifugal force when the disc 100 rotates. The swivel block 300 is block-shaped and is slidably disposed on a groove or track on the edge of the disc 100 along the radial direction of the disc 100. A first pushing inclined surface 310 is provided on the side of the swivel block 300 near the sliding part 210 of the polishing brush 200. The angle design of this inclined surface needs to take into account factors such as the rotational speed of the disc 100, the mass of the swivel block 300, and the thrust required by the polishing brush 200 to ensure that the swivel block 300 can effectively push the polishing brush 200 to slide through the inclined surface when the disc 100 rotates.

[0048] When the disc 100 rotates, the sling block 300 overcomes the elastic force of the first elastic element 410 and slides radially outward along the disc 100 due to centrifugal force. Through the interaction between the first pushing inclined surface 310 and the first pushed inclined surface 211 of the sliding part 210 of the polishing brush 200, the sling block 300 provides a thrust to the polishing brush 200 close to the curtain wall panel, so that the polishing brush 200 can automatically adjust the contact distance with the curtain wall panel according to the change of centrifugal force when the disc 100 rotates, thereby achieving a more uniform polishing pressure at different positions of the disc 100 and solving the problem of uneven polishing.

[0049] The first elastic element 410 can be a spring, the elastic coefficient of which is selected according to actual needs to ensure that it can provide a suitable centripetal force. One end of the spring abuts against the side of the throwing block 300 near the center of the disc 100, and the other end abuts against the groove or track wall of the disc 100.

[0050] The first elastic element 410 provides a centripetal force for the swivel block 300. When the rotation speed of the disc 100 decreases or stops, the first elastic element 410 allows the swivel block 300 to automatically slide towards the center of the disc 100, so that when the disc 100 rotates again, the swivel block 300 can slide outward again under the action of centrifugal force to push the polishing brush 200. At the same time, the presence of the first elastic element 410 can also buffer the impact force of the swivel block 300 during the centrifugal sliding process to a certain extent, protecting the disc 100 and other components from excessive instantaneous force.

[0051] The second elastic element 420 is also a spring, and its elastic coefficient is selected according to the wear condition of the polishing brush 200 and the required compensation force. One end of the spring abuts against the side of the sliding part 210 of the polishing brush 200 near the center of the disc body 100, and the other end abuts against the bottom or side wall of the corresponding groove in the disc body 100.

[0052] The second elastic element 420 provides force to pull the polishing brush 200 away from the curtain wall panel. During polishing, the brush portion 220 of the polishing brush 200 gradually wears down, resulting in reduced contact pressure between it and the curtain wall panel surface. The second elastic element 420 can compensate for this pressure loss through its own elasticity when the polishing brush 200 wears down, ensuring that the polishing brush 200 always maintains appropriate contact pressure with the curtain wall panel surface and ensuring the stability of the polishing effect. In addition, the second elastic element 420 can also play a certain buffering role when the throwing block 300 pushes the polishing brush 200 closer to the curtain wall panel, preventing the polishing brush 200 from being damaged by excessive thrust.

[0053] During operation, connect and fix the disc 100 to the output shaft of the drive motor through the central mounting hole, ensuring a secure connection and smooth rotation of the disc 100. Place the curtain wall panel to be polished on a suitable workbench, adjust the position of the polishing device so that the disc 100 is above the curtain wall panel and the polishing brush 200 maintains an appropriate distance from the surface of the curtain wall panel.

[0054] The drive motor is started, causing the disc 100 to rotate at high speed. As the disc 100 rotates, the sliding block 300, under the action of centrifugal force, overcomes the elastic force of the first elastic element 410 and slides radially outward along the disc 100. The sliding block 300 interacts with the first pushed inclined surface 211 of the sliding part 210 of the polishing brush 200 through the interaction of the first pushing inclined surface 310 and the first pushed inclined surface 211 of the sliding part 210 of the polishing brush 200, pushing the sliding part 210 of the polishing brush 200 to slide axially along the disc 100, so that the brush part 220 approaches the surface of the curtain wall panel. During the polishing process, the polishing brush 200 polishes the surface of the curtain wall panel, making the surface of the curtain wall panel even and clean. At the same time, since the polishing brush 220 will gradually wear down, the second elastic element 420 compensates for the wear of the polishing brush 200 through its own elasticity, ensuring that the polishing brush 220 and the surface of the curtain wall panel always maintain appropriate contact pressure and maintain a stable polishing effect. During the rotation of the disc 100, the sling blocks 300 at different positions automatically adjust the thrust on the grinding brush 200 according to the change of centrifugal force, so that the grinding brush 200 applies a more uniform grinding pressure to the curtain wall panel at different positions of the disc 100, thus solving the problem of uneven grinding.

[0055] Once the curtain wall panel surface has achieved the desired polishing effect, turn off the drive motor. As the rotation speed of the disc 100 gradually decreases, the swivel block 300 slides towards the center of the disc 100 under the elastic force of the first elastic element 410, while the polishing brush 200 moves away from the curtain wall panel surface under the elastic force of the second elastic element 420. Remove the polishing device from the worktable, clean the residual debris and dust from the polishing brush 200, and check the wear condition of each component. If necessary, replace or repair severely worn components to prepare for the next polishing operation.

[0056] By using the centrifugal force to automatically push the polishing brush 200 to slide when the disc 100 rotates, the polishing brush 200 applies relatively uniform polishing pressure to the curtain wall panel at different positions on the disc 100, effectively solving the problem of obvious differences in polishing effect between the center and the edge of the traditional polishing disc, and ensuring uniform polishing of the curtain wall panel surface.

[0057] Because the grinding brush 200 can automatically adjust the contact pressure with the curtain wall panel according to the force on different positions of the disc 100, it avoids the problem of excessive wear due to concentrated force at the center of the grinding disc, thus extending the service life of the grinding brush 200 and reducing the cost and time of replacing grinding parts.

[0058] Under the action of centrifugal force, the throwing block 300 pushes the grinding brush 200 closer to the curtain wall panel, increasing the vertical pressure of the grinding brush 200 on the surface of the curtain wall panel. At the same time, the second elastic element 420 compensates for the wear of the grinding brush 200, ensuring that the grinding brush 200 always maintains sufficient grinding force, which can effectively grind the rough surface of the curtain wall panel, improve the cleanliness of the curtain wall panel surface, and thus improve the overall decorative quality of the imitation stone curtain wall panel.

[0059] In some examples, the sliding part 210 has a receiving space 212 for accommodating the polishing brush 200. The polishing brush 200 also has a sliding shaft 230, which is slidably disposed in the receiving space 212 along the axial direction of the parallel disc 100. The brush part 220 is an elastic steel wire and is mounted on the sliding shaft 230. The brush part 220 is inclined relative to the receiving space 212 and abuts against the inner wall of the receiving space 212 under its own elasticity. The tilt angle is limited by the lower end of the receiving space 212. After the sliding shaft 230 slides downward toward the curtain wall panel, it can drive the brush part 220 to move in the receiving space 212 and change the tilt angle of the brush part 220 relative to the curtain wall panel.

[0060] In some examples, the brush portion 220 extends from the sliding shaft 230 to both sides of the sliding shaft 230. A third elastic member 430 acts on the sliding shaft 230 at one end and on the sliding portion 210 at the other end, providing a force to move the sliding shaft 230 closer to the swivel block 300. The disc body 100 has a centrifugal limiting portion 110 located on the side of the swivel block 300 away from the center of the disc body 100, used to limit the centrifugal sliding position of the swivel block 300. The lower end of the push rod 510 is connected to the sliding shaft 230, and the upper end has a second pushed inclined surface 511. The secondary throwing block 520 is slidably disposed on the throwing block 300 along the radial direction of the disc 100, and has a second pushing inclined surface 521. The second pushing inclined surface 521 abuts against the second pushed inclined surface 511. After the secondary throwing block 520 abuts against the throwing block 300 and the centrifugal limiting part 110, it can centrifugally slide relative to the throwing block 300. After centrifugal sliding, the push rod 510 can be moved by the second pushing inclined surface 521 and the second pushed inclined surface 511. One end of the fourth elastic member 440 acts on the secondary throwing block 520, and the other end acts on the throwing block 300, to provide a force for the secondary throwing block 520 to move centripetally. One end of the fifth elastic member acts on the push rod 510, and the other end acts on the sliding part 210, to provide a force for the push rod 510 to move away from the curtain wall panel.

[0061] For example, the sliding part 210 is internally designed with a receiving space 212 to accommodate other parts of the polishing brush 200. The shape and size of the receiving space 212 are adapted to the sliding shaft 230 and brush part 220 of the polishing brush 200, providing them with room to move. The lower end of the receiving space 212 can limit the tilt angle of the brush part 220, ensuring that the brush part 220 works within a certain angle range to achieve the best polishing effect.

[0062] The sliding shaft 230 is slidably disposed within the receiving space 212 along the axial direction of the parallel disc 100. It serves to connect to and drive the brush section 220. When the sliding shaft 230 slides up and down within the receiving space 212, it can drive the brush section 220 to move, thereby changing the tilt angle of the brush section 220 relative to the curtain wall panel. This design allows the grinding brush 200 to flexibly adjust its contact angle with the curtain wall panel, improving the adaptability of grinding.

[0063] The brush part 220 can be made of elastic steel wire, extending to both sides from the sliding shaft 230. This elastic steel wire material ensures that the polishing brush 220 has sufficient hardness to polish the curtain wall panel, while also possessing a certain degree of elasticity, allowing it to abut against the inner wall of the receiving space 212 under its own elasticity. As the sliding shaft 230 slides downwards towards the curtain wall panel, the brush part 220 moves within the receiving space 212, changing its tilt angle relative to the curtain wall panel, thereby enabling more detailed polishing of different parts and textures on the surface of the curtain wall panel.

[0064] The third elastic element 430 can be a spring, with one end abutting against the side of the sliding shaft 230 near the swivel block 300, and the other end abutting against the sliding part 210. The spring constant is selected according to the adjustment force and frequency required by the polishing brush 200 to ensure that the sliding shaft 230 can be provided with a stable and appropriate force to move towards the swivel block 300.

[0065] The third elastic element 430 provides a force to the sliding shaft 230 to move closer to the swivel block 300. During the polishing process, when the swivel block 300 pushes the sliding part 210, the third elastic element 430 assists the sliding shaft 230 to respond better, allowing the brush part 220 to adjust its tilt angle more quickly to adapt to different polishing conditions. At the same time, when the polishing brush 200 is subjected to external impacts or other disturbances, the third elastic element 430 acts as a buffer, protecting the structural integrity of the polishing brush 200.

[0066] The centrifugal limiting part 110 is part of the interior of the disc body 100 and is located on the side of the sling block 300 away from the center of the disc body 100. It can match the shape of the sling block 300 and limit the centrifugal sliding of the sling block 300.

[0067] The centrifugal limiting part 110 is used to limit the position of the centrifugal sliding block 300. When the sliding block 300 slides outward under the centrifugal force generated by the rotation of the disc 100, it cannot continue to slide outward once it comes into contact with the centrifugal limiting part 110. This not only ensures that the sliding block 300 operates within a safe range, but also provides the triggering condition for the operation of the subsequent secondary sliding block 520.

[0068] The lower end of the push rod 510 is firmly connected to the sliding shaft 230, and the upper end has a second pushed inclined surface 511. The length of the push rod 510 is designed according to the structure of the disc body 100 and the positional relationship between the components to ensure that the thrust of the secondary throwing block 520 can be effectively transmitted to drive the sliding shaft 230 to move.

[0069] The secondary swivel block 520 is also made of a heavy metal material and is slidably mounted on the swivel block 300 along the radial direction of the disc 100. It has a second pushing inclined surface 521, which abuts against the second pushed inclined surface 511 of the push rod 510. When the swivel block 300 abuts against the centrifugal limiting part 110, the centrifugal force generated by the continued rotation of the disc 100 will cause the secondary swivel block 520 to slide centrifugally relative to the swivel block 300. Through the interaction between the second pushing inclined surface 521 and the second pushed inclined surface 511, the push rod 510 moves, which in turn drives the sliding shaft 230 to move, further adjusting the tilt angle of the polishing brush 200 and achieving more precise polishing control.

[0070] The fourth elastic element 440 can be a spring, with one end abutting against the side of the secondary swing block 520 near the center of the swing block 300, and the other end abutting against the swing block 300. The spring constant is selected according to the motion requirements of the secondary swing block 520 to ensure that it can provide a suitable centripetal force for the secondary swing block 520. When the rotation speed of the disc 100 decreases or stops rotating, the fourth elastic element 440 causes the secondary swing block 520 to slide towards the center position of the swing block 300, so that it can slide outward again under the action of centrifugal force next time.

[0071] The fifth elastic element can also be a spring, with one end abutting against the side of the push rod 510 near the center of the disc 100, and the other end abutting against the sliding part 210. Its elastic coefficient is selected according to the buffering and reset force required by the push rod 510. The fifth elastic element provides the force to push the push rod 510 away from the curtain wall panel. After the secondary throwing block 520 pushes the push rod 510 closer to the curtain wall panel, when the centrifugal force disappears or decreases, the fifth elastic element resets the push rod 510, and at the same time drives the sliding shaft 230 and the brush part 220 back to the initial position or appropriate position, preparing for the next grinding adjustment.

[0072] Before the grinding device is started, the brush part 220 of the grinding brush 200 maintains a certain tilt angle under the constraint of its own elasticity and the lower end of the accommodating space 212. Under the action of the third elastic element 430, the sliding shaft 230 is close to the side of the throwing block 300. Under the action of the first elastic element 410, the throwing block 300 is close to the center of the disc 100, the secondary throwing block 520 is close to the center of the throwing block 300 under the action of the fourth elastic element 440, and the push rod 510 is away from the curtain wall panel under the action of the fifth elastic element.

[0073] The drive motor rotates the disc 100, and the sliding block 300, under centrifugal force, overcomes the elastic force of the first elastic element 410 and slides radially outward along the disc 100. The sliding block 300 interacts with the first pushed inclined surface 211 of the sliding part 210 of the polishing brush 200 through the interaction of the first pushing inclined surface 310 and the first pushed inclined surface 211 of the sliding part 210 of the polishing brush 200, pushing the sliding part 210 of the polishing brush 200 to slide axially along the disc 100, bringing the brush part 220 closer to the curtain wall panel. Simultaneously, the third elastic element 430 assists the sliding shaft 230 in responding to the thrust of the sliding block 300, allowing the brush part 220 to adjust its tilt angle as needed for preliminary polishing of the curtain wall panel.

[0074] When the sliding block 300 slides to abut against the centrifugal limiting part 110, the centrifugal force generated by the continued rotation of the disc 100 causes the secondary sliding block 520 to slide relative to the sliding block 300 against the elastic force of the fourth elastic element 440. The secondary sliding block 520 interacts with the second pushed inclined surface 521 and the second pushed inclined surface 511 of the push rod 510 through the interaction, causing the push rod 510 to move, which in turn drives the sliding shaft 230 to slide downwards towards the curtain wall panel. The movement of the sliding shaft 230 causes the brush part 220 to move within the receiving space 212, further changing the tilt angle relative to the curtain wall panel, thus achieving a more refined polishing of the curtain wall panel. During this process, the fifth elastic element acts as a buffer for the push rod 510, preventing the push rod 510 from being damaged due to excessive force.

[0075] After polishing is completed, the drive motor stops rotating. The polishing block 300 slides towards the center of the disc 100 under the action of the first elastic element 410, and the polishing brush 200 moves away from the curtain wall panel under the action of the second elastic element 420. The secondary polishing block 520 slides towards the center of the polishing block 300 under the action of the fourth elastic element 440, and the push rod 510 moves away from the curtain wall panel under the action of the fifth elastic element, driving the sliding shaft 230 and the brush part 220 back to their initial or suitable positions, preparing for the next polishing cycle.

[0076] The 200 sanding brush can automatically adjust its tilt angle according to different sanding conditions, so that it can better fit the shape and texture of the curtain wall panel surface, greatly improving the adaptability of sanding and meeting the sanding needs of various complex curtain wall panels.

[0077] By setting up the secondary swing block 520 and the push rod 510, after the swing block 300 reaches the limit position, the tilt angle of the grinding brush 200 is further finely adjusted, which realizes fine grinding of the curtain wall panel, helps to improve the grinding quality of the curtain wall panel and meet the high requirements of the decorative effect.

[0078] The design of each elastic element not only provides the necessary motion power and cushioning for the components, but also makes the movement of each component in the entire grinding device more stable during operation, thereby enhancing the stability of the equipment and extending its service life.

[0079] In some examples, the brush portion 220 is alternatively disposed on the sliding shaft 230. The polishing brushes 200 are arranged in a group along the radial direction of the disc body 100, and several groups of polishing brushes 200 are arranged circumferentially around the axial direction of the disc body 100. The swivel blocks 300 are also arranged in several circumferentially. One swivel block 300 can push a group of polishing brushes 200 to slide and approach the curtain wall panel through the first pushing inclined surface 310 and the first pushed inclined surface 211.

[0080] For example, the brush part 220 is replaceably mounted on the sliding shaft 230. For instance, the sliding shaft 230 may have a slot or threaded structure, and one end of the brush part 220 may have a matching locking block or nut. This design allows the brush part 220 to be easily disassembled and replaced after wear, without needing to replace the entire polishing brush 200, thus reducing operating costs. Simultaneously, the brush part 220 extends to both sides from the sliding shaft 230, ensuring sufficient polishing coverage on the curtain wall panel.

[0081] The replaceable brush head 220 improves the economy and flexibility of the sanding device. During actual sanding, the brush head 220, as the part in direct contact with the curtain wall panel, experiences frequent wear. When the brush head 220 wears to a certain extent and affects the sanding effect, only the brush head 220 needs to be replaced, instead of replacing the entire sanding brush 200, reducing component replacement costs and time. Furthermore, for curtain wall panels of different materials and sanding requirements, brush heads 220 of different materials, hardness, or shapes can be selected for replacement, further enhancing the adaptability of the sanding device.

[0082] The polishing brushes 200 are arranged in a group along the radial direction of the disc body 100, and multiple groups of polishing brushes 200 are arranged circumferentially around the axial direction of the disc body 100. The sliding part 210 in each group of polishing brushes 200 can slide axially in the groove within the disc body 100. There are also several throwing blocks 300, arranged circumferentially along the edge of the disc body 100, and each throwing block 300 can push a group of polishing brushes 200 to slide and approach the curtain wall panel through its first pushing inclined surface 310 and the first pushed inclined surface 211 of the sliding part 210 of the polishing brush 200. This layout design allows the polishing brushes 200 at each position to automatically adjust their contact pressure and position with the curtain wall panel according to the change of centrifugal force under the action of the throwing blocks 300 when the disc body 100 rotates.

[0083] Multiple sets of polishing brushes 200 are arranged in a circular pattern, ensuring that the entire surface of the curtain wall panel is polished relatively evenly during the rotation of the disc 100. Each swivel block 300 pushes a set of polishing brushes 200, ensuring the consistency of the movement of the polishing brushes 200 at different positions on the disc 100 and avoiding over- or under-polishing in certain areas. At the same time, the coordinated work of multiple sets of polishing brushes 200 increases the polishing coverage area, improves polishing efficiency, and enables the polishing of the curtain wall panel to be completed in a shorter time.

[0084] The replaceable brush part 220 design reduces the cost of component replacement, while allowing for flexible replacement of the brush part 220 according to the needs of different curtain wall panels, improving the adaptability of the grinding device to various curtain wall panels and meeting diverse grinding requirements.

[0085] The optimized layout of the 200 grinding brush and the 300 swivel block allows for more uniform grinding of the curtain wall panel surface, avoiding localized grinding differences. At the same time, the coordinated work of multiple 200 grinding brushes improves grinding efficiency, reduces grinding time, and enhances overall grinding quality.
