Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a GRG sheet metal edge grinding device. Background Technology

[0002] GRG (Glass Fiber Reinforced Gypsum Board) is a precast decorative material made of modified gypsum as the base material and incorporating glass fiber. It boasts advantages such as high strength and lightweight, good plasticity, a smooth surface, and moisture and fire resistance. In the field of building decoration, GRG boards are widely used in interior decoration due to their unique properties and aesthetically pleasing appearance. During the processing of GRG boards, the joints or edges usually require sanding due to processing errors to ensure the installation effect and overall aesthetics of the boards.

[0003] However, most existing sheet metal edge grinding devices on the market are limited in function, and can only perform edge grinding on GRG sheets of specific shapes (such as rectangular or circular), resulting in low adaptability and an inability to simultaneously meet the processing needs of sheets of different shapes. When edge grinding is required on GRG sheets of different shapes, different equipment needs to be changed, increasing production costs. Therefore, this application provides a GRG sheet metal edge grinding device to meet these needs. Utility Model Content

The telescopic ends of the multiple first electric push rods 5 are connected to the processing table 3. The multiple first electric push rods 5 extend and retract together to drive the processing table 3 to rise and fall. When the first electric push rods 5 push the processing table 3 to rise above the turntable 2, a rectangular GRG sheet can be placed on the processing table 3 for edge grinding. When the first electric push rods 5 drive the processing table 3 to fall below the turntable 2, a circular GRG sheet can be placed on the turntable 2 for edge grinding.

[0037] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the processing table 3 is provided with multiple rollers 6, the rollers 6 are arranged along the length of the processing table 3, and the rollers 6 are arranged in multiple rows along the length of the processing table 3, so as to push the rectangular GRG sheet to move on the processing table 3 for edge grinding. Rollers 7 are vertically arranged on both sides of the top of the processing table 3, and push-pull members are provided on the processing table 3 to drive the rollers 7 to move. The push-pull members drive the rollers 7 to move along the width of the processing table 3. The rollers 7 are used to limit and guide the rectangular GRG sheet on both sides.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the through groove 4 penetrates the processing table 3 on one side facing the vertical arm 8. The grinding wheel 11 can pass vertically through the through groove 4. The vertical arm 8 has a vertically opened sliding groove 15. A slider 16 is slidably embedded in the sliding groove 15. A second electric push rod 17 is horizontally installed on the slider 16. The telescopic end of the second electric push rod 17 is connected to the assembly block 10. A guide rod 18 is also horizontally inserted on the slider 16. The guide rod 18 is fixedly connected to the assembly block 10. The extension and retraction of the second electric push rod 17 causes the assembly block 10 to move closer to or away from the turntable 2. A third electric push rod 19 is vertically installed at the top of the vertical arm 8. The telescopic end of the third electric push rod 19 extends into the sliding groove 15 and is connected to the slider 16. The third electric push rod 19 pushes the slider 16 to slide up and down along the sliding groove 15 to adjust the height of the grinding wheel 11. The second electric push rod 17 pushes the assembly block 10 to move horizontally to adjust the horizontal position of the grinding wheel 11 to adapt to different sizes of GRG sheets. In addition, a dust collection hood 13 is provided at the bottom of the side of the vertical arm 8 facing the middle of the base 1.

In this embodiment, the dust collection structure of the vacuum cleaner 14 and the air collection hood 13 adopts the grinding and dust collection structure disclosed in the dust collection grinder disclosed in the prior art patent CN223419211U. In this embodiment, the pneumatic rotary joint 20 adopts the commercially available pure pneumatic rotary joint, and the number of air tubes in this rotary structure is 2 inlet and 2 outlet. In addition, the electric push rods involved in this embodiment are all commercially available straight stainless steel electric push rods.

[0041] The working principle of the technical solution provided by this utility model is as follows:

[0042] In use, when it is necessary to grind the edge of a rectangular GRG sheet, the processing table 3 is lifted by extending multiple first electric push rods 5, so that the processing table 3 is higher than the turntable 2. Then, the rectangular GRG sheet is placed horizontally on the processing table 3. The rollers 7 on both sides of the processing table 3 are moved by extending and retracting the fourth electric push rod 24, so that the rollers 7 abut against the sides of the rectangular GRG sheet. At the same time, the third electric push rod 19 extends and retracts to push the slider 16 to drive the assembly block 10 and the grinding wheel 11 to rise and fall, adjusting the grinding wheel 11 to align with the rectangular GRG sheet. The second electric push rod 17 extends and retracts to push the assembly block 10 to move horizontally, adjusting the horizontal position of the assembly block 10, so that the grinding wheel 11 contacts the grinding edge of the rectangular GRG sheet. The first motor 12 is started to drive the grinding wheel 11 to rotate. At the same time, with the rolling cooperation of the rollers 6 and the rollers 7, the rectangular GRG sheet is moved along the length of the processing table 3, so that the edge of the rectangular GRG sheet can be ground.

[0043] When it is necessary to grind the edge of a round GRG sheet, multiple first electric push rods 5 retract, causing the processing table 3 to descend, so that the turntable 2 passes through the through slot 4 and is higher than the processing table 3. At this time, the round GRG sheet is placed on the turntable 2. The vacuum suction cup 22 on the turntable 2 is connected to the vacuum pumping equipment using the pneumatic rotary joint 20. Suction is generated at the vacuum suction cup 22 to adsorb and fix the round GRG sheet on the turntable 2. Then, the horizontal position and height of the grinding wheel 11 are adjusted by the second electric push rod 17 and the third electric push rod 19. The first motor 12 drives the grinding wheel 11 to rotate, and at the same time, the second motor 21 drives the turntable 2 to rotate, so that the round GRG sheet can be ground.

[0044] During the edge grinding process of GRG sheet, the dust generated during the edge grinding process can be removed by using the vacuum cleaner 14 and the air collection hood 13, so as to avoid dust pollution of the processing environment and harm to the operator's health.
