[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0019] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1-5As shown, a semi-finished calcium sulfate floor surface sander includes two conveyor frames 1, with a conveyor belt 101 between them. The conveyor belt 101 contains a drive roller 102 and a driven roller 103. A motor a104 is mounted on one side of one conveyor frame 1, and one side of the motor a104 is driven by a drive shaft connected to one end of the drive roller 102. The other end of the drive roller 102 is rotatably connected to one side of the other conveyor frame 1 via a bearing. Both ends of the driven roller 103 are rotatably connected to their respective conveyor frames 1 via bearings. A clamping assembly located at the top of the conveyor belt 101 is used to fix floorboards of different widths and prevent displacement. The clamping assembly includes an electric push rod a301, a push plate 302, and a roller 404. A cleaning assembly located at the top of the conveyor belt 101 is used to clean the floor surface after sanding. The cleaning assembly includes a cleaning frame 501, a cleaning groove 503, and a cleaning roller 601.
[0021] The system utilizes the electric push rod a301, push plate 302, and roller 404 in the clamping assembly. By rotating the control handle 202, the height of the polishing roller 206 is controlled to adapt to different floor thicknesses. The length of the electric push rod a301 is adjusted according to different floor widths, ensuring that the roller 404 fits tightly against both sides of the floor, preventing displacement during polishing and the generation of defective products. Furthermore, the cleaning frame 501, cleaning groove 503, and cleaning roller 601 in the cleaning assembly are used to clean the surface of the floor that has just been polished. The powder is then drawn into the filter bag 702 of the collection frame through the exhaust hose 701, further improving the product's smoothness and preventing the cleaned powder from scattering onto other floor surfaces.
[0022] The two conveyor frames 1 are connected to the top of a grinding frame 2. Each grinding frame 2 has a lifting groove 201 on both sides. A control handle 202 is located on the top of the grinding frame 2, and a threaded rod 203 is connected to the bottom of the control handle 202. One end of the threaded rod 203 extends into the interior of the grinding frame 2 and is rotatably connected to a connecting plate 204 via a bearing. Two vertical plates 205 are connected to the bottom of the connecting plate 204, and a grinding roller 206 is positioned between the two vertical plates 205. One end of the grinding roller 206 passes through one of the lifting grooves 201 and is connected to a motor. b207, both sides of the grinding frame 2 are connected to mounting plates 3. An electric push rod a301 is installed on the top of the mounting plate 3. One end of the electric push rod a301 passes through the grinding frame 2 and is connected to a push plate 302. Multiple shrink cylinders 4 are connected to one side of each of the two push plates 302. Multiple springs 401 are installed inside the multiple shrink cylinders 4. An extension column 402 is connected to one side of each spring 401. One end of the extension column 402 passes through the inside of the shrink cylinder 4 and is connected to a mounting bracket 403. Rollers 404 are rotatably connected inside the mounting bracket 403 via a rotating shaft.
[0023] When sanding floors, the lateral vibration and cutting resistance generated by the high-speed rotation of the sanding rollers can easily cause the floor to shift on the conveyor belt surface, resulting in a deviation in the sanding trajectory and the production of defective products. When using this equipment, the electric push rod a301 pushes the push plate 302 at its front end towards the center of the conveyor belt 101, causing the push plate 302 to drive multiple shrink cylinders 4 fixed on it to move synchronously. The spring 401 inside the shrink cylinder 4 always pushes the extension column 402 outward. While the conveyor belt 101 is conveying the floor, the two sides of the floor will contact and slightly compress the spring 401 corresponding to the roller 404. After the spring 401 is compressed, it will generate a force opposite to the direction of deformation, so that the roller 404 fits tightly against the two sides of the floor. Since the roller 404 can rotate freely, when the conveyor belt 101 moves the floor, the roller 404 will roll along with it, providing lateral clamping force while allowing the floor to pass smoothly, effectively preventing the floor from shifting laterally during the conveying and sanding process on the conveyor belt 101.
[0024] The conveyor frame 1 is connected to a gantry frame 5 at its top. A cleaning frame 501 is installed at the bottom of the gantry frame 5. An electric push rod b502 is installed at the top of the gantry frame 5. One end of the electric push rod b502 passes through the gantry frame 5 and is connected to the top of the cleaning frame 501. A cleaning groove 503 is opened inside the cleaning frame 501. A cleaning roller 601 is installed inside the cleaning groove 503. A motor c6 is installed on one side of the cleaning frame 501. One end of the motor c6 is connected to the cleaning roller 601 via a drive shaft. The other end of the cleaning roller 601 is rotatably connected to the inner wall of the cleaning groove 503 via a bearing. A collection frame 7 is installed on one side of one of the conveyor frames 1. An exhaust hose 701 is connected to the top of the collection frame 7. One end of the exhaust hose 701 passes through the gantry frame 5 and extends into the cleaning frame 501. A filter bag 702 is installed inside the collection frame 7. A fan 703 is installed at the bottom of the filter bag 702. Multiple ventilation holes 704 are opened on both sides of the collection frame 7.
[0025] After sanding, the floor surface is prone to retaining a lot of dust particles. These dust particles can easily clump together when damp, affecting product quality. When using this equipment, after the floor is sanded by the sanding roller 206, it is conveyed by the conveyor belt 101 to the area below the cleaning frame 501. Depending on the floor thickness, the height of the cleaning frame 501 can be adjusted by the electric push rod b502, ensuring that the opening of the cleaning groove 503 at the bottom of the cleaning frame 501 is as close as possible to the floor surface, forming a relatively enclosed space. Then, the motor c6 drives the cleaning roller 601 to rotate at high speed within the cleaning groove 503. The rotation direction of the cleaning roller 601 ensures that its bristles effectively contact and sweep the freshly sanded floor surface. The rotating cleaning roller 601 sweeps up the sanding dust and debris adhering to the floor surface. Simultaneously, the air inside the collection frame 7... When the machine 703 operates, a negative pressure is generated inside the collection frame 7. This negative pressure is then transmitted through the exhaust hose 701 to the cleaning groove 503 of the cleaning frame 501. The dust and debris swept up by the cleaning roller 601 are then drawn into the exhaust hose 701 under the action of negative pressure. The dust-laden airflow is then drawn into the collection frame 7 through the exhaust hose 701. Inside the collection frame 7, the filter bag 702 intercepts most of the dust particles, causing them to settle inside the filter bag 702. The filtered, relatively clean air passes through the filter bag 702 and is discharged through the ventilation holes 704 on both sides of the collection frame 7. Through the physical cleaning of the cleaning roller 601 combined with the negative pressure suction, the polishing residue on the floor surface is efficiently removed, and the filter bag 702 collects the residue, preventing dust from scattering and polluting the environment or adhering to other floors.
[0026] Working principle:
[0027] When sanding floors, the lateral vibration and cutting resistance generated by the high-speed rotation of the sanding rollers can easily cause the floor to shift on the conveyor belt surface, resulting in a deviation in the sanding trajectory and the production of defective products. When using this equipment, the electric push rod a301 pushes the push plate 302 at its front end towards the center of the conveyor belt 101, causing the push plate 302 to drive multiple shrink cylinders 4 fixed on it to move synchronously. The spring 401 inside the shrink cylinder 4 always pushes the extension column 402 outward. While the conveyor belt 101 is conveying the floor, the two sides of the floor will contact and slightly compress the spring 401 corresponding to the roller 404. After the spring 401 is compressed, it will generate a force opposite to the direction of deformation, so that the roller 404 fits tightly against the two sides of the floor. Since the roller 404 can rotate freely, when the conveyor belt 101 moves the floor, the roller 404 will roll along with it, providing lateral clamping force while allowing the floor to pass smoothly, effectively preventing the floor from shifting laterally during the conveying and sanding process on the conveyor belt 101.
[0028] After sanding, the floor surface is prone to retaining a lot of dust particles. These dust particles can easily clump together when damp, affecting product quality. When using this equipment, after the floor is sanded by the sanding roller 206, it is conveyed by the conveyor belt 101 to the area below the cleaning frame 501. Depending on the floor thickness, the height of the cleaning frame 501 can be adjusted by the electric push rod b502, ensuring that the opening of the cleaning groove 503 at the bottom of the cleaning frame 501 is as close as possible to the floor surface, forming a relatively enclosed space. Then, the motor c6 drives the cleaning roller 601 to rotate at high speed within the cleaning groove 503. The rotation direction of the cleaning roller 601 ensures that its bristles effectively contact and sweep the freshly sanded floor surface. The rotating cleaning roller 601 sweeps up the sanding dust and debris adhering to the floor surface. Simultaneously, the air inside the collection frame 7... When the machine 703 operates, a negative pressure is generated inside the collection frame 7. This negative pressure is then transmitted through the exhaust hose 701 to the cleaning groove 503 of the cleaning frame 501. The dust and debris swept up by the cleaning roller 601 are then drawn into the exhaust hose 701 under the action of negative pressure. The dust-laden airflow is then drawn into the collection frame 7 through the exhaust hose 701. Inside the collection frame 7, the filter bag 702 intercepts most of the dust particles, causing them to settle inside the filter bag 702. The filtered, relatively clean air passes through the filter bag 702 and is discharged through the ventilation holes 704 on both sides of the collection frame 7. Through the physical cleaning of the cleaning roller 601 combined with the negative pressure suction, the polishing residue on the floor surface is efficiently removed, and the filter bag 702 collects the residue, preventing dust from scattering and polluting the environment or adhering to other floors.
