Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a dust-free grinding device for building engineering technology. Background Technology

[0002] The construction and decoration industry is booming across the country, leading to a corresponding increase in demand for building materials. During installation, the four edges of the materials often need to be sanded for ease of installation. According to a dust-free sanding device for architectural decorative panels (application number CN208773190U), a dust cover is installed on top of a workbench. Inside the dust cover, a sliding mechanism and a sliding plate are installed. The sliding mechanism moves the sliding plate, and a pressure block, consisting of a hydraulic cylinder, a telescopic rod, and a pressure plate, is installed on top of the sliding plate. When sanding the decorative panel, the dust cover door is first opened, and the decorative panel is placed on the sliding plate. The hydraulic cylinder on the pressure block moves the pressure plate on the telescopic rod downwards to fix the panel. At this point, the motor slides to a suitable position via a slide rail, driving the sanding blade on the rotating shaft to sand the decorative panel on the sliding plate. This device is easy to operate, effectively improving work efficiency. Furthermore, the sanding dust is absorbed by a dust collection device inside the dust cover, effectively preventing dust pollution. However, this device can only grind one side of the board. When changing the other side of the board, the position of the board needs to be adjusted manually, which reduces the efficiency of the grinding process. Utility Model Content

[0027] Example 2

[0028] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a filter groove 29 is provided inside the grinder 1 and below the grinder chamber 2. A pull-out drawer 30 is placed inside the filter groove 29, with one end of the drawer 30 extending to the outside of the grinder 1. A filter plate 31 is fixedly connected inside the drawer 30. A pump 32 is fixedly connected to one side of the grinder 1, with one end of the pump 32 extending into the filter groove 29. A third suction tube 35 is fixedly connected to one side of the inner cavity of the grinder chamber 2, and a third suction tube 35 is fixedly connected to the other side of the inner cavity of the grinder chamber 2.

A controller is fixedly connected to one side of the grinder 1. The controller controls the operation of this device. By taking the pull-out drawer 30 out of the filter tank 29, the dust collected on the surface of the filter plate 31 is cleaned. Then the pull-out drawer 30 and the filter plate 31 are pushed back into the filter tank 29 to collect dust.

[0029] In summary, when using this dust-free grinding device for building engineering, open the door on one side of the grinder 1, then place the board onto the top of the fixed platform 15. Next, the telescopic end of the first electric telescopic rod 24 pushes the clamping blocks 25 to move, causing the two clamping blocks 25 to clamp the board. Then, the output end of the second self-locking motor 19 drives the second lead screw 21 to rotate, causing the second lead screw 21 to drive the moving plate 22, which in turn moves the side plate 23, the first electric telescopic rod 24, and the clamping blocks 25. This causes the two clamping blocks 25 to move the board, bringing one side of the board into contact with the grinding disc 28. Then, the output end of the drive motor 27 drives the grinding disc 28 to rotate. The movement of the grinding disc 28, via the extension end of the second electric telescopic rod 40, drives the drive motor 27 and the grinding disc 28 to move, grinding the side of the board. Simultaneously, the pump 32 starts, drawing air and grinding dust from inside the grinding chamber 2 into the filter tank 29 through the third suction pipe 35, the second suction pipe 34, and the first suction pipe 33. The dust is separated by the filter plate 31. Air is drawn in by the pump 32 and then discharged through the other end of the pump 32. After grinding one side of the board, the output of the second self-locking motor 19 drives the second lead screw 21 to rotate, causing the second lead screw 21 to drive the moving plate 22. The first electric telescopic rod 24, clamping block 25, and plate are moved to their initial positions. Then, the output of the first self-locking motor 8 drives the first lead screw 9 to rotate, causing the lead screw 9 to drive the first moving block 10 to move the fixed platform 15 and plate below the first rotating disk 6. Then, the telescopic end of the first electric telescopic rod 24 drives the clamping block 25 to reset and move, releasing the limiting fixation of the plate. Then, the telescopic end of the hydraulic rod 4 pushes the first servo motor 5 to move down, so that the first rotating disk 6 contacts the top of the plate. Then, the output of the first servo motor 5 drives the first rotating disk 6 to rotate, while the output of the third servo motor 16 drives... The second rotating disk 17 is rotated, and the controller makes the first rotating disk 6 and the second rotating disk 17 rotate synchronously to rotate the plate, rotating the other side of the plate to the grinding position. Then the extension end of the first electric telescopic rod 24 pushes the clamping block 25 to move, so that the two clamping blocks 25 limit and fix the plate. Then the extension end of the hydraulic rod 4 drives the first servo motor 5 and the first rotating disk 6 to reset and move. Then the output end of the first self-locking motor 8 drives the first lead screw 9 to reset and rotate, so that the first lead screw 9 drives the first moving block 10, the fixed table 15 and the plate to move to the initial position. Then the grinding work of the remaining three sides is carried out according to the above steps.

[0030] When the first moving block 10 moves, the output end of the second servo motor 14 in the direction of travel of the first moving block 10 drives the take-up roller 13 to rotate, so that the take-up roller 13 takes up the baffle 11. The output end of the second servo motor 14 in the other direction drives the take-up roller 13 to rotate, so that the baffle 11 wrapped around the outside of the take-up roller 13 is released.

[0031] When the moving plate 22 moves, the output end of the fourth servo motor 37 in the direction of travel of the second lead screw 21 drives the winding roller 39 to rotate, so that the winding roller 39 winds up the guide strip 38. The output end of the fourth servo motor 37 in the other direction drives the winding roller 39 to rotate, so that the guide strip 38 wound on the outside of the winding roller 39 is released.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
