[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1 - Figure 5 As shown, a blade grinding angle adjustment mechanism includes a fixed structure 1, a control frame structure 2 bolted to the top of the fixed structure 1, and an adjustment structure 3 bolted to the top of the fixed structure 1 and located on the left side of the control frame structure 2. The fixed structure 1 includes a fixed platform 11, a limit frame 12 bolted to one side of the top of the fixed platform 11, and a drive motor 13 bolted to the top of the fixed platform 11. The control frame structure 2 includes a fixed frame 21 bolted to the top of the fixed platform 11, a limit rotating column 23 rotatably connected to the outer wall of the inner side of the fixed frame 21, an adjustment disc 22 fixedly sleeved on the outer wall of the limit rotating column 23, an adjustment frame 24 bolted to one side of the outer wall of the adjustment disc 22, a telescopic plate 241 slidably connected to the inner side of the adjustment frame 24, and a blade holder 245 bolted to one end of the telescopic plate 241.

[0025] It should be noted that in this embodiment, the limit rotating column 23 is rotated by the drive motor 13, thereby using the limit rotating column 23 to drive the angle of the adjustment frame 24 on the outer wall of the adjustment plate 22, so that the grinding angle can be adjusted by the blade holder 245 installed at one end of the telescopic plate 241.

[0026] The adjustment structure 3 includes an adjustment tank 31 bolted to the top of the fixed platform 11. A fixed toothed disc 33 is bolted to the outer right side of the inner cavity of the adjustment tank 31. The inner side of the outer wall of the adjustment tank 31 is rotatably connected to the outer wall of the limiting rotating column 23. A pushing column 25 is slidably connected to the inner side of the limiting rotating column 23 and located in the inner cavity of the adjustment tank 31. A movable toothed disc 251 is bolted to one end of the pushing column 25. A second return spring 32 is movably sleeved on one side of the movable toothed disc 251. A rotating disc 252 is rotatably connected to the right end of the pushing column 25 and located on the right side of the limiting rotating column 23. A transmission gear 131 is fixedly sleeved on the outer wall of the drive motor 13. A toothed block 221 is welded to the outer wall of the adjustment disc 22. A pointer 222 is bolted to the top of the outer wall of the adjustment disc 22. The outer wall of the transmission gear 131 meshes with the outer wall of the toothed block 221. A measuring scale 34 is welded to the outer right side of the adjustment tank 31.

[0027] It should be noted that in this embodiment, the rotating disk 252 is manually pushed to push the push column 25 into the inner cavity of the adjusting tank 31, thereby causing the push column 25 to drive one side of the movable toothed disk 251 to disengage from the inner side of the fixed toothed disk 33. Then, the drive motor 13 is started, and one end of the drive motor 13 drives the outer wall of the transmission gear 131 to rotate. The outer wall of the transmission gear 131 meshes with the outer wall of the tooth block 221, causing the adjusting disk 22 to rotate through the tooth block 221. The pointer 222 is used as a reference for the measurement 34 to adjust the angle of the adjusting disk 22. Then, the adjustment is manually released, and the second return spring 32 pushes one side of the movable toothed disk 251 to insert the movable toothed disk 251 into the inner side of the fixed toothed disk 33, thereby limiting the push column 25.

[0028] A countertooth block 121 is bolted to the inner side of the left outer wall of the limiting frame 12. A limiting tube 242 is rotatably connected to the inner sides of the left and right sides of the telescopic plate 241 and to the inner side of the adjusting frame 24. Rollers 26 are rotatably connected to the outer walls of both ends of the limiting tube 242 and to the inner side of the limiting frame 12. A limiting plate 246 is fixedly sleeved at one end of the limiting tube 242 and to the left side of the limiting frame 12. A limiting tooth block 247 is bolted to the inner side of the outer wall of one side of the limiting plate 246 and to the left side of the limiting frame 12. A limiting rod 243 is slidably connected to the inner side of the limiting tube 242. A threaded groove 248 is bolted to one end of the limiting rod 243. A rotating handle 244 is rotatably connected to one end of the limiting rod 243. A return spring 249 is movably sleeved on the inner side of the threaded groove 248. The outer wall of the rotating handle 244 is threadedly connected to the inner side of the threaded groove 248.

[0029] It should be noted that, in this embodiment, when adjusting the angle of the adjustment frame 24, the rotating handle 244 is first pushed, causing the inner side of the limiting tube 242 to slide left and right. This causes the limiting plate 246, which is fixedly sleeved on the outer wall of the limiting rod 243, to disengage the limiting tooth block 247 from the inner side of the reverse tooth block 121. Simultaneously, the outer wall of the rotating handle 244 rotates threadedly with the inner side of the threaded groove 248 to limit the angle. The angle can then be adjusted by the adjustment frame 24, while the limiting tube 242 drives the roller. The outer wall of 26 is limited to slide, so that the limiting tube 242 drives the telescopic plate 241 to be limited by the inner side of the limiting frame 12, so that the telescopic plate 241 slides inside the adjusting frame 24. After adjusting the angle of the adjusting frame 24, the rotating handle 244 is dislodged from the inner side of the threaded groove 248, so that the first return spring 249 pushes the rotating handle 244 to reset, thereby inserting the limiting tooth block 247 into the inner side of the reverse tooth block 121, so that it is supported during grinding.

[0030] The working principle of this utility model is as follows: When adjusting the angle of the adjusting frame 24, the rotating handle 244 is first pushed, causing the inner side of the limiting tube 242 to slide left and right. This causes the limiting plate 246, which is fixedly sleeved on the outer wall of the limiting rod 243, to disengage the limiting tooth block 247 from the inner side of the reverse tooth block 121. At the same time, the outer wall of the rotating handle 244 rotates threadedly with the inner side of the threaded groove 248, thus limiting the angle. The angle can then be adjusted by the adjusting frame 24. Simultaneously, the limiting tube 242 drives the roller 2... The outer wall of 6 is limited by rolling, so that the limiting tube 242 drives the telescopic plate 241 to be limited by the inner side of the limiting frame 12, thereby allowing the telescopic plate 241 to slide inside the adjusting frame 24. After adjusting the angle of the adjusting frame 24, the rotating handle 244 is dislodged from the inner side of the threaded groove 248, and the first return spring 249 pushes the rotating handle 244 to reset, thereby inserting the limiting tooth block 247 into the inner side of the reverse tooth block 121, so that it can be supported during grinding.

[0031] The rotating disc 252 is manually pushed to push the pusher 25 into the inner cavity of the adjusting tank 31. This causes the pusher 25 to disengage one side of the movable toothed disc 251 from the inner side of the fixed toothed disc 33. Then, the drive motor 13 is started, and one end of the drive motor 13 drives the outer wall of the transmission gear 131 to rotate. The outer wall of the transmission gear 131 meshes with the outer wall of the tooth block 221, causing the adjusting disc 22 to rotate. The pointer 222 is used as a reference for the measurement 34 to adjust the angle of the adjusting disc 22. Then, the disc is manually released, and the second return spring 32 pushes one side of the movable toothed disc 251, inserting the movable toothed disc 251 into the inner side of the fixed toothed disc 33, thereby limiting the pusher 25.

[0032] The limit rotating column 23 is adjusted by the drive motor 13, thereby driving the adjustment frame 24 on the outer wall of the adjustment plate 22 to adjust the angle of grinding by using the blade holder 245 installed at one end of the telescopic plate 241.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
