In order to improve the safety of the rotor 22 during operation, a shield 24 is provided outside the first rotor, the second rotor and the belt, and the shield 24 may be provided on the third base 235.

Referring to fig. 1, an obliquely extending material collecting table 11 is fixed on a frame 1, a material collecting opening 111 for receiving material rods is formed in the upper end surface of the material collecting table 11, and the material collecting opening 111 is located below the discharge holes 36 in the two groups of feeding mechanisms 3. After the rod grinding is completed, the rod is pushed down into the collecting table 11 by the power cylinder 3331 so as to collect the processed rods in batches. In other embodiments, the discharging of the rod may also be achieved by an air blowing pipe disposed on the frame 1 or the fixed plate 341, where an air outlet of the air blowing pipe is located on a side of the discharging hole 36 away from the collecting table 11 and faces the rod, so as to blow the rod after the processing into the collecting table 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, and the protection plate 25 is located on one side of the grinding wheel 21 and is close to the end face of the feeding mechanism 3, which is a concave arc surface, so that the splashing distance of the chips can be effectively reduced, and the potential safety hazard can be reduced.

The embodiment of the application provides a sharpening machine, which is implemented by firstly placing a plurality of rods into a bin 322 when processing the rods, enabling the rods at the bottommost part to fall into a material channel 327 along a guide inclined plane 3224, then starting a driving piece 323 to push a discharging frame 321 and the bin 322 to a side close to a material channel 35, enabling the rods in the material channel 327 to fall into the material channel 35, detecting the existence of a metal block 3213 by a second inductive switch 3153, shortening a piston rod of the driving piece 323, extending a piston rod of a power cylinder 3331, enabling the bin 322 to pull back the rest rods, and pushing the ends of the rods in the material channel 35 out of a discharging hole 36 by a push rod 332. The fixed motor 344 is started again 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 high speed to feed the material rod with the end part extending out of the discharging hole 36, so that the end part of the material rod is sharpened.

When the grinding mechanism 2 processes the material rods of one group of feeding mechanisms 3, the other group of feeding mechanisms 3 pushes the material rods to the discharge holes 36, and after the material rods extending out of the previous group of feeding mechanisms 3 are grinded, the pushing component 23 is utilized to enable the grinding wheel 21 to feed the material rods of the other feeding mechanisms 3, so that the material rods of the other feeding mechanisms 3 are ground. The two groups of feeding mechanisms 3 are alternately fed and ground in a reciprocating manner, so that the automation degree and the working efficiency are high, and the quality of finished products is good.

The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
