Description

Technical Field

[0001] This utility model relates to the field of glass substrate grinding machine technology, and specifically to a grinding wheel cooling mechanism for a glass substrate grinding machine. Background Technology

[0002] In glass substrate production, the edges of the glass substrate need to be ground and chamfered to improve their strength and surface quality. When the grinding wheel in the grinding machine grinds for a long time, the heat generated is too high and it can easily lose its grinding function. After searching, the existing technology (announcement number: CNCN202322323601.3) describes a cooling mechanism for a double-sided grinding machine. The article describes that "starting the water pump can draw the coolant in the storage chamber into the water tank and inject it onto the workpiece from the upper grinding disc, thereby cooling the workpiece. Furthermore, the used coolant flows into the storage chamber from the drainage holes and drain holes and is filtered by the filter box. After the filter box filters out a certain amount of waste, the handle is pulled to remove the filter box, which can clean the waste in the filter box and then put it back into the storage chamber. At this time, the coolant can be recycled and kept in a relatively clean state for a long time, thereby ensuring the cooling effect." However, the existing technology has the problem that directly injecting coolant during grinding can easily cause some coolant to splash out, and uneven injection of coolant affects the cooling effect. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, a cooling mechanism for the grinding wheel of a glass substrate grinding machine is provided to solve the problems that in the existing technology, direct liquid injection during grinding can easily cause some coolant to splash out, and uneven injection of coolant can affect the cooling effect.

[0004] To achieve the above objectives, a cooling mechanism for the grinding wheel of a glass substrate grinding machine is provided, comprising: a cooling arc-shaped cover and a grinding wheel body, wherein the grinding wheel body is partially enclosed within a groove on the right side of the cooling arc-shaped cover.

[0005] The cooling arc-shaped shroud is equipped with three cooling nozzles: a first cooling nozzle, a second cooling nozzle, and a third cooling nozzle. These nozzles are connected to a cooling water pipe via a liquid guiding channel. A water-sweeping roller brush is installed inside the cooling arc-shaped shroud. A fixed rod is installed in the middle of the water-sweeping roller brush. The upper end of the fixed rod is connected to a transmission block via an external threaded post. A small motor is connected to the upper end of the transmission block via a coupling. A water-blocking scraper is installed on the right side of the water-sweeping roller brush.

[0006] Furthermore, the inner end of the grinding wheel body is connected to a grinding drive mechanism via a grinding wheel support, and a water-blocking sleeve is sleeved on the shaft surface of the grinding drive mechanism.

[0007] Furthermore, a support frame is fixed to the upper end of the cooling arc cover, a cooling water pipe is connected to the outer arc surface of the front side of the cooling arc cover, and a small motor is installed on the upper surface of the cooling arc cover.

[0008] Furthermore, the lower end face of the cooling arc cover is provided with a waste discharge slot, a connecting slot plate is fixed to the right end of the waste discharge slot, and a solid-liquid separation frame is distributed at the lower end of the waste discharge slot.

[0009] Furthermore, the right side of the solid-liquid separation frame is connected to the connecting groove plate via a plug-in plate, a filter screen is placed inside the solid-liquid separation frame, and a drain port is opened at the left end of the solid-liquid separation frame.

[0010] Furthermore, the inner side of the transmission block is screwed to the outer threaded column through an internal threaded groove, and the water-blocking scraper is symmetrically attached to the upper and lower wheel surfaces of the grinding wheel body.

[0011] Furthermore, the cooling nozzle one, cooling nozzle two, and cooling nozzle three are respectively distributed at the upper end, outer end, and lower end of the grinding wheel body.

[0012] The beneficial effects of this utility model are as follows: the cooling mechanism of the grinding wheel in the glass substrate grinding machine utilizes the cooling nozzles inside the cooling arc-shaped hood, which are located at the top, bottom, and sides of the grinding wheel. This allows the multi-directional cooling nozzles to evenly spray the coolant onto the surface of the rotating grinding wheel, increasing the contact area between the grinding wheel and the coolant and improving the cooling efficiency of the grinding wheel. The rotating sweeping brush and water-blocking scraper inside the cooling arc-shaped hood remove the coolant flowing on the surface of the grinding wheel that has exited the hood, effectively reducing coolant leakage and waste, and lowering the cooling cost of the grinding wheel cooling mechanism in glass substrate production.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a cooling mechanism for the grinding wheel of a glass substrate grinding machine, including: a cooling arc-shaped cover 1 and a grinding wheel body 3, wherein the grinding wheel body 3 is partially covered in the groove on the right side of the cooling arc-shaped cover 1.

[0019] The cooling arc-shaped hood 1 has cooling nozzles 1-2, 21-2, and 22-3 installed on its tank wall. Cooling nozzles 1-2, 21-2, and 22-3 are connected to cooling water pipes 6 through a liquid guiding channel 14. A water-sweeping roller brush 7 is installed inside the cooling arc-shaped hood 1. A fixing rod 71 is installed in the middle of the water-sweeping roller brush 7. The upper end of the fixing rod 71 is connected to a transmission block 74 through an external threaded post 75. The upper end of the transmission block 74 is connected to a small motor 72 through a coupling 73. A water-blocking scraper 8 is installed on the right side of the water-sweeping roller brush 7.

[0020] First, the grinding wheel body 3 is driven to rotate by the grinding drive mechanism 5, so that the edge of the glass substrate is in contact with the side surface of the grinding wheel body 3 for grinding. The grinding wheel surface in contact with the glass substrate rotates into the cooling arc cover 1. Cooling liquid delivered by the cooling nozzle 1 2, cooling nozzle 21 and cooling nozzle 3 22 inside the cooling arc cover 1 is sprayed onto the grinding side wheel surface and the upper and lower wheel surfaces. After cooling and spraying, the wheel surface moves to the rotating water sweeping roller brush 7 and water blocking scraper 8, so that the cooling liquid on the wheel surface is scraped off. Then it is removed from the cooling arc cover 1 and the grinding operation is performed again.

[0021] In this embodiment, the inner end of the grinding wheel body 3 is connected to the grinding drive mechanism 5 through the grinding wheel support 32, and the axial surface of the grinding drive mechanism 5 is sleeved with a water-blocking sleeve 31.

[0022] In a preferred embodiment, the grinding drive mechanism 5 drives the grinding wheel body 3 to perform a rotary grinding operation via a rotating shaft. The water-blocking sleeve 31 helps to prevent the cooling liquid from the cooling spray from entering the connection between the rotating shaft and the grinding wheel support 32.

[0023] In this embodiment, a support frame 11 is fixed at the upper end of the cooling arc cover 1, a cooling water pipe 6 is connected to the outer arc surface of the front side of the cooling arc cover 1, and a small motor 72 is installed on the upper surface of the cooling arc cover 1.

[0024] As a preferred embodiment, the cooling arc cover 1 is installed on the glass substrate grinding machine body through the support frame 11, so that the cooling arc cover 1 can be fixed at the side end of the grinding wheel body 3, so that one side of the grinding wheel body 3 grinds the edge surface of the glass substrate while the other side of the wheel surface is cooled.

[0025] In this embodiment, a discharge slot 12 is provided on the lower end face of the cooling arc cover 1, and a connecting slot plate 13 is fixed to the right end of the discharge slot 12. A solid-liquid separation frame 4 is distributed at the lower end of the discharge slot 12. The right side of the solid-liquid separation frame 4 is inserted into the connecting slot plate 13 through a plug-in plate 43. A filter screen 41 is placed inside the solid-liquid separation frame 4, and a drain port 42 is provided on the left end of the solid-liquid separation frame 4.

[0026] As a preferred embodiment, the discharge slot 12 facilitates the discharge of the mixture of impurities and coolant left on the wheel surface into the solid-liquid separation frame 4. After being filtered and separated by the filter screen 41 inside the solid-liquid separation frame 4, the coolant is then discharged and can be reused.

[0027] In this embodiment, the inner side of the transmission block 74 is screwed to the outer threaded post 75 through an internal threaded groove, and the water-blocking scraper 8 is symmetrically attached to the upper and lower wheel surfaces of the grinding wheel body 3. Cooling nozzle 1 2, cooling nozzle 21 and cooling nozzle 3 22 are respectively distributed at the upper end, outer end and lower end of the grinding wheel body 3.

[0028] In a preferred embodiment, the sweeping roller brush 7 is connected to the transmission block 74 of the small motor 72 and rotates (in the opposite direction to the rotation of the grinding wheel body 3). This facilitates the sweeping of coolant from the side surface of the grinding wheel body 3, preventing some coolant from flowing out of the cooling arc-shaped cover 1 as the grinding wheel body 3 rotates. Simultaneously, the water-blocking scraper 8 prevents coolant from leaking from the upper and lower surfaces of the grinding wheel body 3 out of the cover, effectively reducing coolant leakage and waste, and lowering the cooling cost of the grinding wheel cooling mechanism in glass substrate production. Cooling nozzles 1-2, 21-2, and 22 provide multi-directional spray cooling to the surface of the grinding wheel body 3, increasing the contact area between the grinding wheel body 3 and the coolant, and improving the cooling efficiency of the grinding wheel cooling mechanism in the glass substrate grinding machine.

[0029] The grinding wheel cooling mechanism of this utility model for a glass substrate grinding machine can effectively solve the problems in the prior art where direct liquid injection during grinding easily leads to some coolant splashing out and uneven coolant injection affecting the cooling effect. It facilitates increasing the contact area between the grinding wheel and the coolant, improving the cooling efficiency of the grinding wheel, effectively reducing coolant leakage and waste, and lowering the cooling cost of the grinding wheel cooling mechanism in glass substrate production. It is suitable for the grinding wheel cooling mechanism of a glass substrate grinding machine.
