[0027] In the prior art, when adapting to different specifications of motor rotors, only one side of the guide device is adjusted, which will cause the feeding station at the bottom of the guide mechanism to be misaligned with the center part of the motor rotor, so that the position of the device arranged on the feeding station needs to be adjusted. In view of this problem, the motor rotor rolls on the sorting plate 24 arranged on both sides of the bidirectional threaded rod 23 along the long side direction of the sorting plate 24, and the guide block 25 is fixedly connected at the bottom of each sorting plate 24, and the guide block 25 is arranged in a plurality of and arranged in the guide groove 21, and the number is the same as that of the guide groove 21.

Since the center positions of the two sorting plates 24 are always not deviated, the position of the device of the feeding station at the bottom of the width adjusting mechanism 2 does not need to be adjusted.

[0028] Referring to Figure 6 As shown: the center of the guide groove 21 at the center position of the sorting frame 1 is provided with a positioning block 22; the positioning block 22 is provided with a positioning groove 221 along the long side direction of the guide groove 21; the center of the bidirectional threaded rod 23 is provided with a positioning rotating block 231; the positioning rotating block 231 is arranged in the positioning groove 221.

[0030] Referring toFigures 2-7 As shown: the intermittent feeding mechanism 3 is arranged between the sequencing plates 24 on both sides of the bidirectional threaded rod 23; the intermittent feeding mechanism 3 comprises an intermittent rotation assembly 31 and a limiting assembly 32; the intermittent rotation assembly 31 comprises an intermittent rotation block 311 and a slot 312; one end of the intermittent rotation block 311 extends outward from its center and has a rod body, the rod body is provided with a plurality of rod bodies and is arranged at equal angles along the circular edge direction of the intermittent rotation block 311, and the gap between adjacent two rod bodies is used to block the motor rotor; the slot 312 is arranged on the end of the intermittent rotation block 311 away from the rod body, the slot 312 is provided with a plurality of slots and is arranged at equal angles along the circular edge direction of the intermittent rotation block 311, and the number of slots 312 is the same as the number of gaps; the limiting assembly 32 comprises a limiting plug 321, a limiting base 322, a motor 323 and a limiting rotation block 324; the limiting plug 321 is inserted into the slot 312; the limiting base 322 is arranged on the end away from the intermittent rotation block 311, and the end of the limiting plug 321 away from the slot 312 is rotationally connected with the limiting base 322; the motor 323 is installed on the limiting base 322; the limiting rotation block 324 is fixedly connected with the output shaft of the motor 323, the limiting rotation block 324 abuts against the limiting plug 321, the side surface of the limiting rotation block 324 extends outward along the diameter of the limiting rotation block 324 and has a protrusion, and the limiting plug 321 protrudes a raised block on the side close to the limiting rotation block 324; when the protrusion and the raised block are staggered, the limiting plug 321 is inserted into the slot 312, and the intermittent rotation block 311 is in a fixed state; when the protrusion and the raised block abut against each other, the limiting plug 321 is pulled out of the slot 312, and the intermittent rotation block 311 is in a non-fixed state.

[0031] The motor 323 drives the limiting rotation block 324 to rotate at a constant speed, so when the protrusion and the raised block abut against each other, the limiting plug 321 will be separated from the slot 312, so that the intermittent rotation block 311 is in a non-fixed state and can rotate. At this time, the motor rotor between the rod body gaps of the intermittent rotation block 311 can roll along the long edge direction of the sequencing plate 24, thereby driving the intermittent rotation block 311 to rotate, until the limiting plug 321 is inserted into the next slot 312 on the intermittent rotation block 311, so that the intermittent rotation block 311 is fixed again, at this time the protrusion has passed the raised block, and the raised block abuts against the side surface of the limiting rotation block 311 again.

[0032] Reference Figure 7The reset mechanism 33 is arranged between the limiting plug block 321 and the limiting base 322; the reset mechanism 33 comprises a convex rod 331 and a reset spring 332; the side wall of the limiting plug block 321 extends outwardly in the direction of the limiting base 322 and is provided with the convex rod 331; one end of the reset spring 332 is connected with the convex rod 331, and the other end is connected with the limiting base 322; when the convex block and the convex block are staggered, the reset spring 332 is in the initial state; when the convex block and the convex block abut, the reset spring 332 is in the stretched state.

[0033] The limiting rotating block 324 rotates to drive the convex block to rotate, and each time the convex block and the convex block abut, the limiting plug block 321 is pulled out of the insertion slot 312, so that the reset spring 332 is stretched. The limiting rotating block 324 continues to rotate, so that the convex block and the convex block are staggered, the reset spring 332 returns to the initial state, and until the convex block of the limiting plug block 321 abuts against the limiting rotating block 324.

[0034] Referring to Figure 2 As shown, the sorting plate 24 is provided with a limiting groove 4 near one end of the feeding station.

[0035] The motor rotor moves along the long edge direction of the sorting plate 24 and is stopped in the limiting groove 4, and can be carried and transferred by the machinery in the feeding station.

[0036] Referring to Figures 1-7 As shown, one end of the bidirectional threaded rod 23 extends out of the side wall of the sorting rack 1 and is fixedly connected with a rotating disc 5, and the rotating disc 5 extends outwardly and is provided with a grabbing rod 51.

[0037] The operator can hold the grabbing rod 51 to drive the rotating disc 5 to rotate, and the rotating disc 5 can drive the bidirectional threaded rod 23 to rotate, so as to control the distance between the sorting plates 24 located on both sides of the bidirectional threaded rod 23.

[0038] In operation, the upper surface of the sorting rack 1 is inclined, and the motor rotor rolls along the long edges of the sorting plate 24 on both sides of the bidirectional threaded rod 23. Due to the cooperation of the guiding block 25 at the bottom of the sorting plate 24 and the guiding groove 21, and the rotation of the bidirectional threaded rod 23, the sorting plate 24 can be symmetrically moved, which can adapt to different specifications of the motor rotor without adjusting the position of the feeding station device. The positioning block 22 and the positioning groove 221 of the central guiding groove 21 of the sorting rack 1 cooperate with the positioning rotating block 231 of the bidirectional threaded rod 23 to ensure that the bidirectional threaded rod 23 rotates centrally. In the intermittent feeding mechanism 3, the motor 323 drives the limiting rotating block 324 to rotate at a constant speed. When the convex block and the convex block abut, the limiting plug block 321 is pulled out of the plug groove 312, the intermittent rotating block 311 is non-fixed and can rotate, and the motor rotor drives it to rotate until the limiting plug block 321 is inserted into the next plug groove 312 to be fixed. At the same time, the state of the convex block and the convex block changes to make the reset spring 332 stretch and retract, which affects the abutting state of the limiting plug block 321 and the limiting rotating block 324. The motor rotor stops when it moves to the stop groove 4 of the sorting plate 24, and can be carried by the feeding station machinery. The operator can hold the rotating disc 5 and rotate the grab rod 51 to rotate the bidirectional threaded rod 23, thereby controlling the spacing of the sorting plate 24.
