Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a fan-shaped nozzle. Background Art

[0002] The edges of glass products generally need to be edged by a U-groove grinding wheel. In order to avoid dry grinding during edge grinding, the grinding wheel needs to be cooled and cleaned. Generally, a grinding wheel water cover is set between the drive device and the grinding wheel so that the water cover can spray water during edge grinding to cool and clean the grinding wheel.

[0003] The grinding wheel water shield has a fan-shaped nozzle (such as Figure 1 As shown in FIG. 1 , the existing fan-shaped nozzle includes an arc-shaped plate 1′, on which a plurality of water spray holes 2′ are arranged. The directions of the water spray holes 2′ on the arc-shaped plate 1′ are inclined and face a specific direction. After the arc-shaped plate 1′ is installed as a whole, the spray angle of the water spray holes 2′ cannot be adjusted. In actual applications, due to the long-term use of the grinding wheel or the need to match different grinding wheels, the thickness of the grinding wheel varies. At this time, if the spray angle of the water spray hole is not adjusted, the spray direction cannot be aligned with the U-shaped groove on the edge of the grinding wheel, which will directly affect the cooling and cleaning effects.

[0004] In addition, for different grinding wheels, different grinding wheel speeds or different glass materials, the requirements for the spray point spacing (the arc angle between the spray points corresponding to adjacent water spray holes on the edge of the grinding wheel) will also be different. Since the existing water spray holes have a fixed water spray angle, the spray point spacing cannot be adjusted, and the flexibility of use is poor and the practicality is low. At the same time, it will also affect the cooling and cleaning effects to a certain extent. Utility Model Content

[0005] The utility model aims to provide a fan-shaped nozzle to solve at least one of the above problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] In the present technical solution, after the position of the arc plate is installed, since a number of universal nozzles are fixedly installed on the front of the arc plate, and the plurality of universal nozzles are arranged in an arc shape and are all connected to the water spray chamber, in order to adapt to the different thicknesses of the grinding wheel in the grinding wheel water cover, the upper and lower angle positions of the universal nozzles can be adjusted to achieve alignment between the injection point and the U-shaped groove on the edge of the grinding wheel (the U-shaped groove is located in the middle position of the thickness direction of the grinding wheel edge), thereby solving the problem of injection point alignment. In addition, by adjusting the left and right angles of each universal nozzle individually, the spacing between the injection points on the edge of the grinding wheel can be adjusted. In summary, the present technical solution solves the problem that the prior art cannot adapt to grinding wheels of different thicknesses, has poor flexibility of use, low practicality, and the cooling and cleaning effects need to be improved.

[0009] Furthermore, in order to more conveniently realize the fixed installation of the universal nozzle and the arc plate, a plurality of threaded mounting holes are provided in the arc groove, and the universal nozzle is threadedly matched with the threaded mounting holes.

[0010] Furthermore, in order to ensure compatibility with the curvature of the grinding wheel, the curvature of the arc-shaped plate and the layout curvature of the plurality of threaded mounting holes are consistent with the curvature of the grinding wheel.

[0011] Furthermore, in order to ensure the sealing of the water spray chamber, a sealing installation groove is provided on the outer side of the arc groove, and a sealing ring is provided in the sealing installation groove.

[0012] Furthermore, in order to provide more installation holes and facilitate different installation requirements, the arc groove includes two arc-shaped docking positions, and the sealing installation groove is provided with a shape adapted to the arc-shaped docking positions.

[0013] Furthermore, the mounting plate is provided with a connecting hole, the connecting hole is connected to an internal water inlet pipe, the internal water inlet pipe is docked with any arc-shaped docking position, and the internal water inlet pipe is connected to the external water inlet pipe through a connecting seat.

[0014] The beneficial effects of the utility model are as follows: in the technical solution, after the position of the arc plate is installed, since a number of universal nozzles are fixedly installed on the front of the arc plate, the plurality of universal nozzles are arranged in an arc shape and are connected to the water spray chamber, in order to adapt to the different thicknesses of the grinding wheel in the grinding wheel water cover, the upper and lower angle positions of the universal nozzles can be adjusted to achieve the alignment of the injection point with the U-shaped groove on the edge of the grinding wheel (the U-shaped groove is located in the middle position of the thickness direction of the grinding wheel edge), thereby solving the problem of injection point alignment. In addition, by adjusting the left and right angles of each universal nozzle individually, the spacing between the injection points on the edge of the grinding wheel can be adjusted. In summary, the technical solution solves the problem that the prior art cannot adapt to grinding wheels of different thicknesses, has poor flexibility of use, low practicality, and the cooling and cleaning effects need to be improved.
