Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a polishing water grinding sheet. Background Art

[0002] Diamond water grinding disc, also known as diamond soft grinding disc, is a flexible processing tool made of diamond as abrasive and combined with composite materials. There is Velcro cloth on the back, which is fastened to the joint of the grinder. It is used for grinding and can perform special-shaped processing on materials such as stone, ceramics, glass, and floor tiles. It is suitable for stone polishing, line chamfering, curved plates and special-shaped stone processing. It can also be used for special-shaped processing, repair and renovation of marble, concrete, cement floors, terrazzo, microcrystalline glass, artificial stone, floor tiles, glazed tiles, and vitrified tiles. It has strong grinding force, good durability, good softness, clarity and gloss, and is an ideal stone grinding tool. The existing cooling method for water grinding discs is usually to first connect an external water injection pipe through the water inlet of the grinder. The water source flows through the flow channel inside the grinder and the grinding disc, and finally flows out from the water outlet on the lower surface of the grinding disc.

[0003] Patent number: CN202220373803.1 is named as a polishing water grinding disc. By setting up multiple heat dissipation grooves as cooling water channels, the cooling water can be easily and effectively flowed and dissipated to the water grinding disc of the device during high-speed rotation, thereby improving the service life of the water grinding disc. At the same time, the inner wall of the bowl-shaped structure can facilitate the cooling water to flow to the other end, further improving the cooling efficiency. The leakage hole of this structure has no barrier structure. During the use of the grinding disc, some debris will enter the grinding disc through the hole, increasing the wear of the grinding disc and reducing the service life of the grinding disc.

[0013] Furthermore, the sheet is connected to one side of the electric rotor through a Velcro layer.

[0014] Compared with the existing technology, the advantages of the present invention are: the sheet body is bonded to one side of the electric rotary head through a Velcro layer, and the water receiving ring receives water through the water inlet groove to the side wall of the water outlet ring. During the rotation of the sheet body, water is discharged from the water outlet hole into the water outlet ring cavity, which can dissipate heat from the cavity of the water outlet ring. After passing through the filter screen, the water flows out through the leakage hole, which can dissipate heat from the grinding surface and the contact surface. The filter screen can block impurities and debris from entering the sheet body during the polishing process, reduce the blockage of the filter screen by debris during the polishing process, reduce some debris from entering the grinding disc through the holes, reduce the wear of the grinding disc, and increase the service life of the grinding disc.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Working principle: The sheet 1 is adhered to one side of the electric rotary head through the Velcro layer 2, and the water receiving ring 3 allows water to enter the side wall of the water outlet ring 4 through the water inlet groove. During the rotation of the sheet, water is discharged from the water outlet hole into the water outlet ring cavity, which can dissipate heat to the cavity of the water outlet ring. After passing through the filter 5, the water flows out through the leakage hole 11, which can dissipate heat to the grinding surface and the contact surface. The filter is rotated and fixed in the thread groove on the inner side of the grinding surface through the thread 9. At the same time, the extrusion spring is fixed to the limit groove 12. The filter can prevent impurities and debris from entering the sheet during the polishing process. The spring causes the filter to vibrate during the rotation of the electric rotary head, reducing the blockage of the filter by debris during the polishing process, reducing some debris from entering the grinding disc through the holes, reducing the wear of the grinding disc, and increasing the service life of the grinding disc.
