Specifically, the material is vibrated by the bottom of the vibrating plate 512 to ascend along the spiral track 5121, and during the ascending process, along with the narrowing of the spiral track 5121 and the screening of a series of tracks, a part of the material falls to the bottom and is vibrated again to ascend along the spiral track 5121, and the ascending material finally reaches the discharge end in a single row and single column manner. Therefore, the disordered materials are automatically, orderly and accurately conveyed, and the single materials are gradually output, so that the orderly material reversing of the feeding mechanism 51 is facilitated. The vibration plate 512 is further provided with a vibration controller 5122 for controlling the on/off, adjusting the vibration frequency, and the like.

Specifically, in the discharging process, the materials are individually discharged to the discharging port 511 until any end surface of the materials contacts with the guide 541, and the materials push the guide 541 at the front part outwards under the action of force. The reversing assembly 54 further includes a bracket for mounting the guide member 541, wherein the upper end of the guide member 541 is rotatably connected to the bracket 542 and can swing within a certain range. The lower end of the guiding element 541 is provided with a bending part 5413 which can partially or completely extend into the concave part 31 or the small hole 32 of the cylindrical material 3, and the bending part 5413 and the guiding element 541 are bent towards the discharging hole 511 at an angle slightly larger than 90 degrees. During the discharging process, the cylindrical material 3 pushes out the bending portion 5413 of the guide 541, and the end of the recess 31 faces the bending portion 5413, the bending portion 5413 can catch the recess 31 when the cylindrical material 3 falls, so that the flat end 33 inclines downward and slides down to the feeding end 5311 of the discharging channel 531, thereby completing the reversing. However, if the flat end 33 faces the bending portion 5413, the bending portion 5413 cannot catch the cylindrical material 3, and the cylindrical material 3 falls into the vibration tray 512, and the direction change and the transportation cannot be completed. In addition, if the feed member 53 is filled with the material, the material overflows from the opening of the feed end 5311, and even if the end of the concave portion 31 faces the bent portion 5413, the flat end 33 collides with the cylindrical material 3 at the opening of the feed end 5311 in the process of being inclined downward, and thus falls into the vibration plate 512. Therefore, the reversing and conveying can be completed only when the guiding member 53 is not full and the end of the concave portion 31 of the cylindrical material 3 faces the bending portion 5413 during discharging, and the functions of automatically recognizing the end surface of the cylindrical material 3 and uniformly reversing the random two end surfaces of the cylindrical material 3 to the flat end 33 are provided.
