[0020] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0021] As Figures 1 to 3 shown, the present utility model discloses a grinding wheel knife sharpening device, which includes a base body 1. A first blade grinding wheel 2 for grinding the blade edge of one side of the tool and a second blade grinding wheel 3 for grinding the blade edge of the other side of the tool are provided on the base body 1. And a bevel grinding wheel 4 for grinding the inclined surface between the blade edge and the blade body of the tool is provided between the first blade grinding wheel 2 and the second blade grinding wheel 3. The bevel grinding wheel 4 is connected with a moving mechanism 5 capable of driving the bevel grinding wheel 4 to move.

[0022] The base body 1 serves as a platform for fixing the grinding wheel and other components. The first blade grinding wheel 2 and the second blade grinding wheel 3 are respectively used for grinding the blade edges on both sides of the tool, which can more evenly restore the sharpness of the blade edges and improve the grinding efficiency. During the use of the tool, due to the inconsistency of the cutting force and the material hardness, the wear on the blade edge and the inclined surface is generally uneven, resulting in problems such as increased cutting resistance, uneven cutting edge, and shortened tool life. The bevel grinding wheel 4 is used to grind the transition bevel between the blade edge and the blade body, so that the width and thickness of the bevel are within a suitable range, thereby ensuring the cutting performance of the tool. Since the thickness of the tool will decrease during the grinding process, the moving mechanism 5 is required to drive the bevel grinding wheel 4 to move back and forth between the first blade grinding wheel 2 and the second blade grinding wheel 3, so as to realize the function of grinding the bevel.

[0023] While the first blade grinding wheel 2 and the second blade grinding wheel 3 grind the two side surfaces of the tool to maintain the sharpness of the blade edge, through the setting of the bevel grinding wheel 4, the width and thinness of the bevel are maintained, the cutting performance of the tool is ensured, the need for subsequent secondary processing is reduced, and the inconvenience and cost caused by frequent disassembly and assembly of the tool are reduced.

[0024] In the embodiment, the first blade grinding wheel 2 and the second blade grinding wheel 3 are arranged at intervals in the up and down direction, so that the first blade grinding wheel 2 and the second blade grinding wheel 3 can independently contact the corresponding side surface of the tool, and the grinding of one side grinding wheel will not be affected by the movement of the other side grinding wheel during the grinding process, avoiding unnecessary interference during the grinding process. The first blade grinding wheel 2 and the second blade grinding wheel 3 are arranged at intervals in the up and down direction. When both the first blade grinding wheel 2 and the second blade grinding wheel 3 correspond to the blade edge, the bevel grinding wheel 4 arranged between the first blade grinding wheel 2 and the second blade grinding wheel 3 can correspond to the transition bevel between the blade edge and the blade body, and the space is compact.

[0025] The moving mechanism 5 includes a first slide rail 52 disposed on the base body 1 and arranged in the front-rear direction. The bevel grinding wheel 4 is connected to a first support frame 51, and the first support frame 51 is slidably connected to the first slide rail 52.

The first support frame 51 is connected to the first slide rail 52, thereby allowing the bevel grinding wheel 4 to slide along the specified direction. In the case where the thickness of the tool becomes smaller during the grinding process, by adjusting the position of the first support frame 51 on the first slide rail 52, the bevel grinding wheel 4 can accurately grind the bevel surface.

[0027] A first driving mechanism 53 capable of driving the first support frame 51 to slide along the first slide rail 52 is provided between the first support frame 51 and the base body 1.

[0028] The first driving mechanism 53 is connected between the first support frame 51 and the base body 1 and is used to drive the first support frame 51 to slide along the first slide rail 52 to realize the position adjustment of the bevel grinding wheel 4. The first driving mechanism 53 can be in the form of electric, pneumatic or hydraulic drive, etc. The movement of the grinding wheel is automated through the first driving mechanism 53, so that the feed speed and position of the grinding wheel can be accurately controlled through programming or presetting, improving the controllability and repeatability of the grinding process.

[0029] The first blade grinding wheel 2 is connected to a second support frame 61. A second slide rail 62 arranged in the front-rear direction is provided on the base body 1.

[0030] The second support frame 61 is used to carry the first blade grinding wheel 2 to ensure the stability of the grinding wheel during the grinding process. The second slide rail 62 provides guidance for the second support frame 61 so that it can slide along the front-rear direction. The first fastener 63 is used to lock the position of the second support frame 61 on the second slide rail 62 to prevent the change of the grinding wheel position during the grinding process, avoiding uneven grinding or tool damage caused by the offset of the grinding wheel position. The first fastener 63 can be completed by means such as bolts, clamps, electromagnetic locks, pneumatic / hydraulic locking devices, etc.

[0031] The base body 1 is provided with a receiving cavity 11. Both the first slide rail 52 and the second slide rail 62 are arranged in the receiving cavity 11. The base body 1 is provided with an outlet 12 for the first support frame 51 and the second support frame 61 to extend out of the receiving cavity 11.

[0032] By arranging the first slide rail 52 and the second slide rail 62 inside the accommodation cavity 11 and leaving an outlet 12 for the first support frame 51 and the second support frame 61 to extend out of the accommodation cavity 11, the influence of the external environment on the slide rails is reduced.

[0033] The base body 1 is provided with an extension part 13, and a third slide rail 71 arranged in the front-back direction is provided on the extension part 13. The second blade grinding wheel 3 is connected with a third support frame 72. The third support frame 72 is slidably connected to the third slide rail 71. A second fastener 73 that abuts against the third support frame 72 and can limit the third support frame 72 from sliding on the third slide rail 71 is arranged between the third support frame 72 and the extension part 13.

[0034] The extension part 13 can be used for installing the third slide rail 71. The third support frame 72 can slide along the third slide rail 71, and the position of the third support frame 72 on the third slide rail 71 is locked by the second fastener 73, so that the position of the second blade grinding wheel 3 can be adjusted in the front-back direction. The third slide rail 71 can also be set as a guiding mechanism such as a ball screw, a linear bearing or a guide groove, etc. The second fastener 73 can be completed by means such as bolts, clamps, electromagnetic locks, pneumatic / hydraulic locking devices, etc.

[0035] The knife grinding device further includes a guide rail 81 arranged in the left-right direction. The base body 1 is slidably connected to the guide rail 81. The base body 1 is connected with a second driving mechanism 82 that can drive the base body 1 to slide along the guide rail 81.

[0036] By arranging the base body 1 to be slidably connected to the guide rail 81, the first blade grinding wheel 2, the second blade grinding wheel 3, and the bevel grinding wheel 4 can move relative to the tool left and right, so as to realize the grinding of the tool. The second driving mechanism 82 can be in forms such as electric, pneumatic or hydraulic drive, etc. Through the arrangement of the second driving mechanism 82, the automatic movement of the base body 1 is realized, so that the feed speed and position of the base body 1 can be precisely controlled by programming or presetting, and the controllability and repeatability of the grinding process are improved.

[0037] The materials of the first blade grinding wheel 2, the second blade grinding wheel 3, and the bevel grinding wheel 4 all include diamond.

[0038] By arranging that the materials of the first blade grinding wheel 2, the second blade grinding wheel 3, and the bevel grinding wheel 4 all include diamond, the first blade grinding wheel 2, the second blade grinding wheel 3, and the bevel grinding wheel 4 have excellent wear resistance, so as to achieve the purpose of grinding the blade and the bevel between the blade and the blade body.

[0039] Such as Figure 4 、 Figure 5As shown, taking a circular knife as an example, the first blade grinding wheel 2 is used to grind the first grinding surface 94 of the circular knife, and the second blade grinding wheel 3 grinds the second grinding surface 93 of the circular knife, thereby improving the sharpness of the blade 91. The inclined surface grinding wheel 4 grinds the third grinding surface 92 to reduce the cutting resistance when the circular knife cuts the material and improve the flatness of the cutting edge of the material.

[0040] This grinding wheel knife sharpening device is not limited to grinding circular knives, and can also be applied to knives such as serrated knives. By adjusting the position and angle of the grinding wheel, it is possible to ensure that the blades and inclined surfaces of different knives are precisely ground, improving the cutting performance and service life of the knives.
