Description

Technical Field

[0001] This utility model relates to the field of filter grinding disc technology, specifically to a combined grinding disc structure for multiple filter specifications. Background Technology

[0002] The grinding disc is the most important working part of the grinding machine. When grinding filters, multiple filters are waxed and adhered to the grinding disc, which is then placed in the corresponding grinding machine to perform the filter thinning operation. Each filter can be removed from the machine after grinding is completed.

[0003] Conventional grinding discs use an integral design with a fixed disc size and hardness, which can only be used to process a single type of filter. Processing different sizes of filters requires replacing the entire grinding disc, which takes more than 30 minutes and seriously affects production efficiency. When the edges and corners are damaged, the entire grinding disc also needs to be replaced, which increases production costs.

[0004] Therefore, it is necessary to invent a combined grinding disc structure with multiple filter specifications to solve the above problems. Utility Model Content

[0007] Preferably, the lower snap-fit ​​block is snapped into the outer snap-fit ​​groove, and the upper snap-fit ​​block is snapped into the inner snap-fit ​​groove, thereby improving the snap-fit ​​strength through the outer snap-fit ​​groove and the inner snap-fit ​​groove.

[0008] Preferably, the edge of the top plate has an inner groove, and the edge of the bottom plate has an outer groove, to facilitate mating with subsequent parts.

[0009] Preferably, the bottom end of the inner grinding disc is fixedly connected to an inner flange, and the bottom end of the outer grinding disc is fixedly connected to an outer flange, which engage with the inner and outer grooves through the inner and outer flanges.

The lower locking block 3 is locked to the outer locking groove 802, and the upper locking block 301 is locked to the inner locking groove 502. The locking strength is improved by the outer locking groove 802 and the inner locking groove 502. The edge of the top plate 201 has an inner groove 10, and the edge of the base plate 2 has an outer groove 11 to facilitate cooperation with subsequent parts. The bottom end of the inner grinding plate 5 is fixedly connected with an inner flange 501, and the bottom end of the outer grinding plate 8 is fixed... An outer flange 801 is connected, and an inner flange 501 engages with the outer flange 801, the inner flange 10, and the outer flange 11. The inner flange 501 engages with the inner flange 10, and the outer flange 801 engages with the outer flange 11, further strengthening the connection. A grinding motor 9 is located below the rotating disk 1, and the output end of the grinding motor 9 is fixedly connected to the bottom end of the rotating disk 1.

When changing specifications, only the corresponding first connecting nail 4 and second connecting nail 7 need to be removed to replace the damaged or different-sized grinding discs. There is no need to stop the machine and disassemble the entire structure. When rinsing is required, the water storage plate 6 is installed, and the entire structure is rinsed using rinsing equipment. Debris is discharged through the drain hole 12 and the drain valve 13 to keep it clean.
