[0043] Working principle:

[0044] The plurality of motor stator blanks cut into sections are poured into the storage frame 4 and above the lower end of the conveying belt 24 in the lifting machine 2, the speed reducing motor 23 is started to rotate the rotating shaft, and then drive one of the transmission rollers 22 to rotate, so as to drive the conveying belt 24 to operate through the other transmission roller 22, and then continuously drive the plurality of supporting plates 25 to move from the front direction of the conveying belt 24, so as to lift the motor stator blanks one by one upwards, and the above principle is the prior art.

[0045] It is worth mentioning that: since each supporting plate 25 is arranged with high left and low right, the elevation blank 5 lifted by the supporting plate 25 will roll to the right along the slope of the supporting plate 25 until the elevation blank 5 is blocked by the limiting plate 26 on the right; under normal circumstances, the outer peripheral surface of the elevation blank 5 should be rolled and fitted on the top outer wall of the supporting plate 25, and the central axis of the elevation blank 5 is distributed in front and back, so that the elevation blank 5 can smoothly roll to the right, but since the elevation blanks 5 in the storage frame 4 are distributed in disorder, the central axis of the elevation blank 5 lifted by the supporting plate 25 may also be distributed left and right, although it can also roll along the supporting plate 25, but cannot pass through the slot hole 261 on the limiting plate 26 on the right and the sleeve 31 in the material guide assembly 3 and move to the arc-shaped turning groove 32, even if it can move to the arc-shaped turning groove 32, but the distribution direction after leaving the straight material guide groove 33 does not meet the feeding requirement.

[0046] The present application is characterized in that a plurality of rectangular through holes 241 are arranged in the conveying belt 24, and each of the rectangular through holes 241 is parallel to each other, and each of the rectangular through holes 241 is arranged in the middle of the conveying belt 24, and each of the grooves 251 is arranged in the front of the rectangular through hole 241, and the opening of the groove 251 is communicated with the inside of the rectangular through hole 241, and when the elevation blank 5 is lifted by the conveying belt 24, the elevation blank 5 is rolled backward due to the slope of the conveying belt 24, and then the elevation blank 5 is slowly slid rightward along the slope of the conveying belt 24, and when the elevation blank 5 is above the groove 251, the elevation blank 5 is dropped down through the groove 251 and the rectangular through hole 241 and is returned to the storage frame 4, and the elevation blank 5 is not continuously fed backward, so that the elevation blank 5 which is not in the required position is automatically removed, and the value of a is slightly larger than the diameter of the elevation blank 5, and the value of c is less than 2 / 3 of the value of a, and the front-to-back width of the groove 251 is less than the axial length of the elevation blank 5. Figure 4

[0047] When the elevation blank 5 is lifted by the conveying belt 24, the elevation blank 5 is rolled rightward along the slope of the conveying belt 24, and then the elevation blank 5 is slowly slid backward along the slope of the conveying belt 24, and when the elevation blank 5 is above the groove 251, the elevation blank 5 is dropped down through the groove 251 and the rectangular through hole 241 and is returned to the storage frame 4, and the elevation blank 5 is not continuously fed backward, so that the elevation blank 5 which is not in the required position is automatically removed, and the value of a is slightly larger than the diameter of the elevation blank 5, and the value of c is less than 2 / 3 of the value of a, and the front-to-back width of the groove 251 is less than the axial length of the elevation blank 5. Figure 5

[0048] Then, when the elevation blank 5 is lifted by the conveying belt 24, the elevation blank 5 is rolled rightward along the slope of the conveying belt 24, and then the elevation blank 5 is slowly slid backward along the slope of the conveying belt 24, and when the elevation blank 5 is above the groove 251, the elevation blank 5 is dropped down through the groove 251 and the rectangular through hole 241 and is returned to the storage frame 4, and the elevation blank 5 is not continuously fed backward, so that the elevation blank 5 which is not in the required position is automatically removed, and the value of a is slightly larger than the diameter of the elevation blank 5, and the value of c is less than 2 / 3 of the value of a, and the front-to-back width of the groove 251 is less than the axial length of the elevation blank 5.

[0049] ​​If the super high blank 6 with the length exceeding the standard is mixed into the storage frame 4, when the super high blank 6 slides to the screening unit 34 along the linear guide groove 33, the upper end of the super high blank 6 is blocked by the upper inner wall of the blocking sleeve 342 and stays above the upper end of the blocking sleeve 342, at this time, the super high blank 6 is just located inside the partition passage 3414 on the moving plate 341, then the sensing end of the position sensor 344 detects the super high blank 6 and drives the retracting end of the traction cylinder 343 to retract inward, thereby driving the moving plate 341 to move left along the guide notch groove 331, so as to push the super high blank 6 to move right by the pushing block 3413, in this process, the right side of the partition plate 3412 is inserted into the below of an adjacent height blank 5 above the super high blank 6 by the guide slope 3416, an adjacent height blank 5 above the super high blank 6 will roll onto the upper outer wall of the partition plate 3412, and each height blank 5 above the super high blank 6 will be lifted by a certain distance, so that the super high blank 6 is separated and each height blank 5 above the super high blank 6 is prevented from moving downward, when the partition passage 3414 is completely moved to the right of the linear guide groove 33, the super high blank 6 will fall outside the storage frame 4 by its own gravity and the slope of the moving plate 341 to realize automatic rejection.

[0050] If it is necessary to adjust the inclination angle of the lifting machine 2, the retracting end of the adjusting cylinder 73 can be driven to extend outward or retract inward, thereby driving the upper end of the lifting machine 2 to swing upward or downward by the connecting rod 75 and the two swing rods 74, so as to realize the adjustment of the inclination angle of the lifting machine 2; when the upper end of the lifting machine 2 swings upward or downward, the lower end of the lifting machine 2 will slide backward or forward along the two arc-shaped tracks 71 by the two connecting shafts 72, and the fixed end of the adjusting cylinder 73 will also rotate relative to the chassis 1, since one end of the arc-shaped turning groove 32 is rotatably connected to the end opening of the sleeve 31, therefore, when the inclination angle of the lifting machine 2 changes, the slope of the guide assembly 3 can remain unchanged.

[0051] The present application can extract the segment materials in the material box in a specified direction, and make the inclined segment materials gradually change to vertical state by the guide assembly 3, and then automatically enter the cutting equipment without relying on manual operation, so as to simplify the operation steps, improve the processing efficiency, reduce the labor cost, and reduce the labor intensity; in addition, the present application can automatically reject the segment materials with the length exceeding the standard mixed into the storage frame 4 to prevent them from flowing into the cutting equipment, and also does not need manual sorting, and can prevent the segment materials with the axial direction not meeting the requirements from entering the linear guide groove 33 to ensure continuous and stable feeding.

[0052] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some of the technical features can be replaced by equivalent ones; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
