In other embodiments, the discharging of the material bar may also be realized by an air blowing pipe disposed on the frame 1 or the fixing plate 341, and an air outlet of the air blowing pipe is located at a side of the discharging hole 36 away from the material collecting platform 11 and faces the material bar, so as to blow the processed material bar down to the material collecting platform 11.

Referring to fig. 7, in order to prevent the chips from splashing when the grinding wheel 21 processes the material rod, a protection plate 25 is further fixed on the second base 233 through bolts, the protection plate 25 is located on one side of the grinding wheel 21, and the end face close to the feeding mechanism 3 is a concave arc face, so that the splashing distance of the chips can be effectively reduced, and the potential safety hazard is reduced.

The implementation principle of the sharpening machine in the embodiment of the application is as follows: when processing the material rod, earlier put into feed bin 322 with many material rods, the material rod that is located the bottommost can follow direction inclined plane 3224 and fall to the material way 327 in, then start driving piece 323 in order to pass blowing frame 321 and feed bin 322 to the one side that is close to silo 35 for the material rod in the material way 327 falls into silo 35, and second inductive switch 3153 detects the existence of metal block 3213 this moment, and make driving piece 323 the piston rod shorten, then power cylinder 3331's piston rod extension, and feed bin 322 is with all the other material rods setback, push rod 332 pushes out discharge opening 36 with the material rod tip in the silo 35. The fixed motor 344 is then started to drive the driving wheel 342 and the driven wheel 343 to rotate, so as to drive the material rod to rotate, and then the pushing assembly 23 drives the grinding wheel 21 rotating at a high speed to feed the material rod with the end extending out of the discharging hole 36, so as to sharpen the end of the material rod.

When the grinding mechanism 2 processes the material rods of one group of feeding mechanisms 3, the other group of feeding mechanisms 3 push the material rods to the discharging holes 36, and after the material rods extending out of the feeding mechanisms 3 are ground, the pushing assembly 23 is used for feeding the grinding wheel 21 to the material rods of the other group of feeding mechanisms 3, so that the material rods of the other group of feeding mechanisms 3 are ground. The alternate feeding and the grinding processing of the two groups of feeding mechanisms 3 are realized in a reciprocating manner, the automation degree and the working efficiency are high, and the quality of finished products is good.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
