DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0018] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged out of the general proportion, and the said schematic diagrams are only examples, which should not limit the scope of protection of the present utility model herein. In addition, in actual production, the three-dimensional spatial dimensions of length, width and depth should be included.

[0019] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0020] Figures 1 - 3 Shown is the entire structural schematic diagram of an integrated rough grinding and fine grinding louver disc of the present utility model. Please refer to Figures 1 - 3 , an integrated rough grinding and fine grinding louver disc of the present embodiment includes an impeller base plate 100. A plurality of uniformly distributed first blades 110 are fixed on the radial surface of the outer peripheral side of the impeller base plate 100. A drive shaft 200 is fixed at the center of the back surface of the impeller base plate 100, and the drive shaft 200 is connected to the output end of the motor. A core disc 300 is snap-fitted and installed on the front surface of the impeller base plate 100. A plurality of uniformly distributed second blades 310 are fixed on the radial surface of the outer peripheral side of the core disc 300. The second blades 310 and the first blades 110 are arranged in an alternating manner, and the second blades 310 and the first blades 110 are uniformly distributed along the outer peripheral side of the impeller base plate 100. After being inserted into the front surface of the impeller base plate 100, the impeller base plate 100 is fixedly inserted through a locking member 400.

[0021] The front surface of the impeller base plate 100 has a mounting groove 120 coaxial with it, and the core plate 300 is fitted and matched with the mounting groove 120. At the same time, the core plate 300 is flush with the outer surface of the impeller base plate 100. There are several avoidance grooves 130 on the radial circumference of the mounting groove 120 that are fitted and matched with the second blade 310, and the avoidance grooves 130 penetrate through the outer peripheral side of the impeller base plate 100. With the cooperation of the mounting groove 120 and the avoidance grooves 130, rapid positioning can be carried out between the impeller base plate 100 and the core plate 300, so that during the high-speed rotation of the louver disk, the core plate 300 will not radially slip off from the impeller base plate 100, ensuring the evenness of blade grinding and the use stability of the louver disk. Specifically, when fine grinding is required, the core plate 300 is directly placed into the mounting groove 120, so that the root of the second blade 310 is stuck into the avoidance groove 130 to form a preliminary positioning. Subsequently, the locking component 400 is screwed into the positioning screw hole 320 and the internal thread screw hole 210, and thus the rapid switching and installation of the louver disk are completed. Removing the core plate 300 is for rough grinding, and different supporting grinding precisions can be switched according to actual needs. The overall structure is simple, the disassembly and installation operations are convenient, which is conducive to popularization and application.

[0022] It can be understood that the number of the corresponding second blades 310 on the outer peripheral side of the core plate 300, that is, the number of the second blades 310 between adjacent first blades 110, including the number of the avoidance grooves 130, can be set in a supporting manner according to the actual needs of rough grinding / fine grinding, and this embodiment does not limit this.

[0023] There is also an avoidance hole 140 in the center of the mounting groove 120 that communicates with the internal thread screw hole 210, and the diameter of the avoidance hole 140 is larger than the diameters of the internal thread screw hole 210 and the positioning screw hole 320. Since the thickness of the impeller base plate 100 is relatively thin, in order to enable the threaded rod to form a longer connection stroke, the device cleverly sets an internal thread screw hole 210 corresponding to the positioning screw hole 320 at the axis of the driving shaft 200. In this way, the threaded rod can directly pass through the impeller base plate 100 and be screwed into connection with the internal thread screw hole 210, improving the connection stability of the louver disk. There is an internal thread screw hole 210 at the inner axis of the driving shaft 200 that communicates with the mounting groove 120, and there is a positioning screw hole 320 corresponding to the internal thread screw hole 210 at the axis of the core plate 300; among them, the locking component 400 is a threaded rod, and the threaded rod is thread-matched with the positioning screw hole 320 and the internal thread screw hole 210. Here, the locking component 400 can adopt a threaded rod, and the nut of the threaded rod can adopt an internal hexagonal or external hexagonal structure. During installation, since the core plate 300 is embedded and snapped into the inner side of the impeller base 10, and the radial force acts between the two during grinding, only by slightly tightening the threaded rod between the impeller base plate 100, the driving shaft 200 and the core plate 300 can form a stable clamping force, and the operation is very simple.

[0024] In summary, for the integrated rough grinding and fine grinding louver disc of this embodiment, when fine grinding is required, directly place the core disc 300 into the installation groove 120, so that the root of the second cutter blade 310 is stuck into the avoidance groove 130 to form a preliminary positioning. Subsequently, screw the locking component 400 into the positioning screw hole 320 and the internal thread screw hole 210. In this way, the quick switching and installation of the louver disc are completed. Removing the core disc 300 is for rough grinding, and different supporting grinding precisions can be switched according to actual needs. The overall structure is simple, the disassembly and assembly operations are convenient, which is conducive to popularization and application.

[0025] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
