[0024] Reference Figures 1 to 5 This utility model discloses a dust-removing flat sander, comprising a main body 2, which is H-shaped. A conical bucket is fixedly connected to the lower inner surface of the main body 2, and a fixing pipe 7 is fixedly connected to the lower surface of the conical bucket. Multiple fixing pipes 7 are provided, and the inner wall of each fixing pipe 7 is provided with threads 18. An installation groove 15 is formed on the outer arc surface of each fixing pipe 7. A through hole is formed on the side surface of the installation groove 15, and a sliding element 20 is slidably connected within the through hole. A spring 19 is fixedly connected to the side surface of the installation groove 15 near the sliding element 20. The other end of the spring 19 is fixedly connected to one end of the side surface of the sliding element 20. A fixing element 16 is fixedly connected to the through hole away from the sliding element 20. The other end of the sliding component 20 is fixedly connected to a limiting plate 17. A connecting pipe 12 is provided near the second thread 18 of the fixed pipe 7. There are two connecting pipes 12. A thread 14 is provided on the outer arc surface of the connecting pipe 12 near the second thread 18. A limiting groove 13 is formed on the connecting pipe 12 near the limiting plate 17. A collection box 9 is provided on the inner wall of the main body 2 away from the conical hopper. The upper surface of the collection box 9 is fixedly connected to one of the fixed pipes 7. A vacuum cleaner 8 is provided on the side surface of the connecting pipe 12. One end of the connecting pipe 12 near the collection box 9 is fixedly connected to the output end of the vacuum cleaner 8, and one end of the other connecting pipe 12 is fixedly connected to the input end of the vacuum cleaner 8. The fixing pad is circular, thus fixing both ends of the workpiece.

[0025] A sanding roller 10 is rotatably connected to the inner wall of the sliding frame 3. A motor 11 is fixedly connected to the side surface of the sliding frame 3. The output end of the electric push rod 4 is fixedly connected to the sliding frame 3. The sliding frame 3 and the inner wall of the fixed frame 1 are slidably connected. The sliding frame 3 is U-shaped. A fixed frame 1 is fixedly connected to the upper surface of the main body 2. An electric push rod 4 is fixedly connected to the upper surface of the fixed frame 1.

[0026] A fixing pad is fixedly connected to the spiral column 6 near the lower inner surface of the main body 2. A fixing hole is opened on the upper inner surface of the main body 2. A threaded hole is opened on the upper surface of the connecting plate 5. The spiral column 6 is threadedly connected to the inner wall of the threaded hole of the connecting plate 5. The output end of the motor 11 passes through the sliding frame 3 and the sanding roller 10 and is fixedly connected. The connecting plate 5 is fixedly connected to the inner side wall of the main body 2 near the fixing frame 1.

[0027] Working Principle: When using this equipment, first place the workpiece on the upper surface of the main body 2, near the fixing hole. Then, turn the spiral column 6 to drive the fixing pad to move towards the workpiece surface until the fixing pad firmly presses the workpiece. At this time, start the motor 11 to drive the sanding roller 10 to rotate and perform sanding operations on the workpiece. At the same time, the electric push rod 4 and the vacuum cleaner 8 start synchronously. The electric push rod 4 pushes the sliding frame 3 to reciprocate, assisting the sanding process. The vacuum cleaner 8 generates suction, causing the sanding debris to fall into the conical hopper through the fixing hole, and then be transported to the collection box 9 for centralized collection via the fixing pipe 7 and the connecting pipe 12. When the vacuum cleaner 8 needs maintenance or replacement, first, pull up the sliding part 20 near the output and input ends of the vacuum cleaner 8. At this time, the spring 19 is compressed, causing one of the limiting plates 17 to disengage from the limiting groove 13 of the connecting pipe 12, thereby releasing the limiting fixation of the connecting pipe 12 connected to the vacuum cleaner 8. Next, rotate the vacuum cleaner 8 in the reverse direction to separate the thread 14 on the connecting pipe 12 connecting the output and input ends of the vacuum cleaner 8 from the thread 18 in the fixed pipe 7, thus completing the disassembly from the fixed pipe 7. Finally, move the collection box 9 a certain distance on the inner wall of the main body 2 to easily remove the vacuum cleaner 8 and the connecting pipe 12 for maintenance or replacement. When reinstalling the vacuum cleaner 8, first move the collection box 9 a certain distance away from the conical hopper. Then, align the connecting pipes 12 at both ends of the vacuum cleaner 8 with the fixed pipe 7, pull up the sliding member 20, and rotate the vacuum cleaner 8 to achieve connection and fixation through the cooperation of the thread 14 and the thread 18. After fixing, release the sliding member 20, and the limiting plate 17 will reset under the action of the spring 19 and re-lock into the limiting groove 13, completing the limitation of the vacuum cleaner 8 and thus realizing the installation of the vacuum cleaner 8.
