[0049] A support column 1224 is provided on the frame 10, a support spring 1225 is provided on the support column 1224, and the top of the support spring 1225 abuts against the bottom of the slider 1223;

[0050] A second slide bar 1226 is horizontally provided in the slider 1223, one end of the second slide bar 1226 is rotatably connected to a second connecting block 1227, and the second connecting block 1227 is connected to a second handwheel installed on the side of the slider 1223 through a second screw;

[0051] The other end of the second slide bar 1226 is provided with a connecting shaft 1227 connected to the first driving assembly, and the roller 123 is installed at the end of the connecting shaft 1227.

[0052] It should be noted that in the prior art, the roller is fixed by a clamp block. When adjustment is required, the bolt is loosened, and the lifting is adjusted through the screw. The front and rear positions cannot be adjusted. After adjusting the position, the clamp block is fixed by the bolt again.

[0056] Please refer to Figure 1 , in a preferred embodiment of the present application, the grinding wheel (blocked by the frame and not shown in the drawings) is installed on the rotating shaft 15, and the rotating shaft 15 is installed on the frame 10 through the bearing seat 16;

[0057] The second driving assembly includes a second motor 17 and a pulley assembly connecting the second motor 17 and the rotating shaft 15.

[0058] In a preferred embodiment of the present application, the surface of the grinding wheel is an inwardly concave arc shape, and this arc shape is concentric with the contour of the roller 123, so that the end of the needle body between the roller 123 and the arc-shaped track 121 will be ground during the process of entering the initial grinding position and turning out of the final grinding position. Because during the rotation of the roller 123, the needle body between the roller 123 and the arc-shaped track 121 rotates at least one full circle, the end of the needle body will be ground into a conical shape.

[0059] Please refer to Figure 1 , in a preferred embodiment of the present application, the position of the bearing seat 16 on the frame 10 can be adjusted up and down. The frame 10 is provided with a scale 18, and the scale 18 is located on both sides of the bearing seat 16, so that the heights of the two bearing seats 16 at both ends are adjusted uniformly, thereby ensuring the accuracy of grinding.

[0060] Please refer to Figure 1 , in a preferred embodiment of the present application, a pressing piece 19 is provided at the top of the feeding box 11. The feeding box 11 is inclined. The pressing piece 19 is used to block the needle bodies to be sharpened in the feeding box 11, and at the same time, the needle bodies to be sharpened enter between the arc-shaped track 121 and the roller 123 one by one under the action of their own gravity.

[0061] Preferably, the bottom of the pressing piece 19 is arc-shaped, and this arc shape is concentric with the contour of the roller 123.

[0062] In summary, in the present utility model, by using the automatic flattening component 14 to replace manual operation, the needle body offset due to the vibration of the equipment is intermittently flattened, thereby improving the sharpening efficiency.

[0063] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. Moreover, the above-described embodiments only represent several implementation manners of the present utility model.
