[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] Reference Figure 1-Figure 5 As shown, the scalpel sharpening and grinding equipment of this embodiment includes a frame 1 and a grinding mechanism 2, a loading frame 3 and a transfer arm 4 arranged on the frame 1, the loading frame 3 is used to place the scalpel to be processed, the transfer arm 4 is used to transfer the scalpel, the frame 1 is provided with a rotating disk 5, the rotating disk 5 is provided with a plurality of circumferentially distributed fixing mechanisms 6, the fixing mechanisms 6 are used to fix the scalpel, the grinding mechanism 2 includes an upper grinding wheel 21 and a lower grinding wheel 22, the upper grinding wheel 21 and the lower grinding wheel 22 are arranged adjacent to the rotating disk 5, the upper grinding wheel 21 and the lower grinding wheel 22 are arranged at intervals, the upper grinding wheel 21 is located on the upper side of the rotating disk 5, and the lower grinding wheel 22 is located on the lower side of the rotating disk 5.

[0019] The scalpels are stacked in the loading frame 3, and there is a transfer block on the lower side of the loading frame 3, which transfers the lowest scalpel to a fixed position in turn. This structure is a prior art and will not be described in detail in this application. After the scalpel is in the transfer position, it is transferred by the transfer arm 4.

[0020] Through the above technical solution, the equipment operates to sharpen the scalpels one by one. The transfer arm 4 sequentially transfers the scalpels in the loading frame 3 to the fixing mechanism 6 of the rotating disk 5. During the rotation of the rotating disk 5, it stops periodically to load the scalpels. The fixing mechanism 6 fixes the scalpel blades. As the rotating disk 5 rotates, the scalpels on the fixing mechanism 6 pass through the upper grinding wheel 21 and the lower grinding wheel 22 in sequence, thereby grinding the upper and lower sides of the scalpels. After grinding is completed, when the rotating disk 5 stops to load the scalpels, the unloading arm removes the polished scalpels.

[0021] After the scalpel is fixed, both sides of the scalpel can be polished at one time without turning it over or taking it in and out, which has high polishing efficiency.

[0022] As an improved specific embodiment, the fixing mechanism 6 includes a fixing seat 61, a fixing block 62 is provided on the fixing seat 61, a movable groove 51 is provided on the rotating disk 5, the fixing seat 61 is slidably arranged in the movable groove 51, a return spring 52 is provided in the movable groove 51, and the return spring 52 is connected to the fixing seat 61, and a first cylinder 71 and a second cylinder 72 are provided on the frame 1, the position of the first cylinder 71 matches the position of the upper grinding wheel 21, and the position of the second cylinder 72 matches the position of the lower grinding wheel 22.

[0023] Through this technical solution, some scalpels have both curved and straight edges. After the rotating disk 5 rotates to sharpen the curved edge, the first and second cylinders 71 and 72 operate, driving the corresponding fixed base 61 to move horizontally, allowing the upper and lower grinding wheels 21 and 22 to sharpen the straight edge of the scalpel. After sharpening is completed, the first and second cylinders 71 and 72 return to their original positions, which in turn resets the return spring 52 and the fixed base 61. The fixed base 61 slides within the movable groove 51, maintaining a stable position.

[0024] As an improved specific implementation, a driven block 611 is provided on the fixing seat 61 , and the driven block 611 extends downward.

[0025] Through the above technical solution, the operation of the first cylinder 71 / the second cylinder 72 pushes the driven block 611 to move, thereby driving the fixed seat 61 to move, and the driving is stable.

[0026] As an improved specific embodiment, a limit block 511 is provided at the opening of the movable groove 51, and a receiving groove 612 is provided on the fixed seat 61. The return spring 52 is located in the receiving groove 612, one end of which is in contact with the limit block 511, and the other end of which is in contact with the bottom of the receiving groove 612.

[0027] Through the above technical solution, the operation of the first cylinder 71 / second cylinder 72 drives the fixed seat 61 away from the rotating disk 5. At this time, the return spring 52 is compressed. After the straight portion of the scalpel blade is polished, the first cylinder 71 / second cylinder 72 is reset, and the return spring 52 is reset, thereby resetting the fixed seat 61. The return spring 52 is set in the receiving groove 612 and is stable in position.

[0028] As an improved specific implementation, a lower fixing groove 81 is provided on the fixing seat 61 , and the shape of the lower fixing groove 81 is consistent with the shape of the surgical blade.

[0029] Through the above technical solution, when the transfer arm 4 places the scalpel on the fixed seat 61, the scalpel is located in the lower fixed groove 81, and the fixed block 62 moves to fix the scalpel, making the position of the scalpel more stable, thereby improving the stability during the sharpening process.

[0030] As an improved specific implementation, an upper fixing groove 82 is provided on the fixing block 62 , and the shape of the upper fixing groove 82 is consistent with the shape of the surgical blade.

[0031] Through the above technical solution, after the transfer arm 4 places the scalpel on the fixed seat 61, the fixed block 62 moves to fix the scalpel, and the scalpel is located in the upper fixed groove 82, making the position of the scalpel more stable, thereby improving the stability during the sharpening process.

[0032] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
