[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0020] See also Figure 1-3 The utility model provides a technical solution for an automatic knife sharpening device: an automatic knife sharpening device, comprising a frame 1, a driving assembly mounted on the upper end of the frame 1, and a supporting plate 5 connected to the upper end of the frame 1 through the driving assembly, a vertical adjustment assembly mounted on one side of the upper end of the frame 1 adjacent to the supporting plate 5, and a grinder 36 mounted on the vertical adjustment assembly;
[0021] An adjusting groove 51 and a blade limiting groove 57 are provided on the upper surface of the carrier plate 5. The adjusting groove 51 and the blade limiting groove 57 are T-shaped. A static clamping plate 56 is provided at one end of the carrier plate 5. An adjusting seat 52 is installed on the inner side of the adjusting groove 51 near the other end of the carrier plate 5. A second adjusting screw 53 is threadedly connected to the adjusting seat 52. One end of the second adjusting screw 53 is located inside the blade limiting groove 57 and is rotatably connected to a dynamic clamping plate 55. The dynamic clamping plate 55 corresponds to the static clamping plate 56. The other end of the second adjusting screw 53 is connected to an adjusting handle 54. The adjusting handle 54 and the second adjusting screw 53 are flippable. When the blade needs to be sharpened, the blade is placed in the blade limiting groove 57. The adjusting handle 54 is flipped to make it perpendicular to the second adjusting screw 53. Then the adjusting handle 54 is rotated to drive the second adjusting screw 53 to rotate. As a result, the second adjusting screw 53 is threadedly connected to the adjusting seat 52, and the second adjusting screw 53 is pushed along the inner side of the adjusting groove 51 to push the clamping plate 55 closer to the static clamping plate 56, thereby limiting and fixing the blade, which is convenient for subsequent sharpening operations.
[0022] The driving assembly includes two limiting slide rails 41 symmetrically mounted on the upper end of the frame 1. A driving screw 42 is provided on the upper end of the frame 1 between the two limiting slide rails 41. The two ends of the driving screw 42 are located on the upper surface of the frame 1 and are respectively connected to the driving motor 4 and the positioning shaft seat 2. The positioning shaft seat 2 is rotatably connected to one end of the driving screw 42. The output end of the driving motor 4 is fixed to the other end of the driving screw 42. A driving seat 43 and a limiting slide seat 44 are respectively provided on the lower surface of the carrying plate 5 corresponding to the driving screw 42 and the limiting slide rail 41. There is a threaded connection between the driving seat 43 and the driving screw 42. The limiting slide 44 and the limiting slide rail 41 are connected in a sliding manner. When the blade is clamped and fixed, the driving motor 4 is controlled to work so that it rotates to drive the driving screw 42 to rotate. When the driving screw 42 rotates, the threaded connection between the driving seat 43 and the driving screw 42 will cause the driving seat 43 to drive the supporting plate 5 to move linearly on the driving screw 42. At the same time, the supporting plate 5 will also move along the limiting slide rail 41 to ensure stability during movement. In this way, the blade can be driven to move toward the grinder 36, which is convenient for sharpening the blade using the grinder 36.
[0023] The vertical adjustment assembly includes a mounting base 3 mounted on the upper end of the frame 1 on one side of the bearing plate 5. Two limiting slide bars 32 are symmetrically mounted on one side of the mounting base 3, and a first adjusting screw 31 is provided on one side of the mounting base 3 between the two limiting slide bars 32. A connecting base 33 is commonly connected to the two limiting slide bars 32 and the first adjusting screw 31. A fixing plate 34 is mounted on the outer side of the connecting base 33. The outer side of the fixing plate 34 is connected to the grinder 36 through a fixing buckle 35. The grinder 36 can be taken The handheld grinder is installed on the fixed plate 34 by fixing the buckle 35 with the bolts, or a small grinder is used to fix it on the fixed plate 34. It should be noted that after the blade is fixed on the dynamic clamping plate 55 and the static clamping plate 56, the position of the supporting plate 5 on the frame 1 is adjusted to sharpen the knife using the grinding sheet of the grinder 36, and the position of the grinding sheet of the grinder is adapted to the position of the knife. It is only necessary to adjust the position of the supporting plate 5 to use the grinding sheet to sharpen the knife.
[0024] The bottom end of the first adjusting screw 31 is rotatably connected to the bottom of the mounting seat 3, and the top end of the first adjusting screw 31 passes through the top of the mounting seat 3 and is connected to an adjusting wheel 37. The connecting seat 33 and the two limiting slide bars 32 are slidably connected, and the connecting seat 33 and the first adjusting screw 31 are threadedly connected. When the height position of the grinder 36 needs to be adjusted, it is only necessary to rotate the adjusting wheel 37 to drive the first adjusting screw 31 to rotate. Since the first adjusting screw 31 and the connecting seat 33 are threadedly connected, when the first adjusting screw 31 rotates, the connecting seat 33 will move linearly along its surface. Therefore, by rotating the adjusting wheel 37 forward or reversely, the connecting seat 33 can be adjusted to move up or down on the first adjusting screw 31, thereby driving the grinder 36 to be adjusted up or down.
[0025] The working principle of the present utility model is as follows: when in use, the blade is placed in the blade limiting groove 57, and then the adjusting handle 54 is rotated to drive the second adjusting screw 53 to rotate, and the second adjusting screw 53 is used to push the dynamic clamping plate 55 closer to the static clamping plate 56, thereby limiting and fixing the blade;
[0026] After the blade is clamped and fixed, the adjusting wheel 37 is rotated to drive the first adjusting screw 31 to rotate. The rotation of the first adjusting screw 31 is used to adjust the height of the connecting seat 33, thereby adjusting the height of the fixing plate 34 and the grinder 36 so that the grinding disc of the grinder 36 corresponds to the height of the blade;
[0027] Furthermore, by controlling the operation of the drive motor 4, its rotation drives the drive screw 42 to rotate, so that the drive seat 43 drives the supporting plate 5 to move linearly on the drive screw 42, thereby driving the blade to move toward the grinding plate of the grinder 36, making it convenient to use the grinder 36 to sharpen the blade.
[0028] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
