[0031] Both the fourth gear 351 and the fifth gear 352 are meshed and connected to both sides of the third gear 34.

[0032] Specific working principle

[0033] The staff first places the silkworm pupae on the conveying track 21 for conveying. As Figure 1 shown, after being conveyed to the square notch positions on both sides of the conveying plate 1, under the drive of the motor 31, the rotating rod 32 rotates. At the same time, during the rotation of the rotating rod 32, it will drive the rotation of the first gear 331 and the third gear 34 at the same time. Under the rotation of the third gear 34, it will also drive the fourth gear 351 and the fifth gear 352 on both sides to rotate. At this time, the first reciprocating lead screw 3511 and the second reciprocating lead screw 3521 inside the fourth gear 351 and the fifth gear 352 will slide in the opposite direction due to the different rotation directions of the fourth gear 351 and the fifth gear 352. As Figure 1 shown, when it is conveyed to the square notch position on the right side of the conveying plate 1, the pushing plate 3512 slid and driven by the second reciprocating lead screw 3521 pushes the silkworm pupa into the square notch on the right side of the conveying plate 1, and is clamped by the two side clamping plates 15 and rotates counterclockwise. At this time, affected by the rotation of the rotating rod 32, the first gear 331 rotates at the same time, driving the second gear 332 and the cutting blade 333 to rotate together. When the silkworm pupa is conveyed counterclockwise by the conveying plate 1 to the top position, a part of the vertical cocoon head of the silkworm pupa will be cut off by the cutting blade 333 to expose the inside. Then when it rotates to the square notch position on the left side of the conveying plate 1, the internal pupa is picked out by the collecting plate 3522 facing the direction of the cocoon pupa and falls back onto the conveying track 21 for conveying again. The remaining cocoons are clamped by the clamping plates 15 and continue to be conveyed by the conveying plate 1 to the square notch at the bottom of the conveying plate 1. At this time, the double-headed telescopic rod 13 on this side contracts inward, and the clamping plates 15 release the cocoons, finally completing the separation of the cocoons and pupae;

[0034] It should be noted that the first gear 331 is in meshing connection with the second gear 332 and the rack 22, which can ensure that the rotation speed of the conveying disk 1 driven by the rotation of the motor 31 is consistent with the rotation speed of the conveying track 21. Similarly, the third gear 34 is in meshing connection with the fourth gear 351 and the fifth gear 352, which can also ensure that it is consistent with the position of the square notch of the conveying disk 1.

[0035] In addition, due to the influence of the rotation of the third gear 34 on the fourth gear 351 and the fifth gear 352, the rotation directions of the fourth gear 351 and the fifth gear 352 are different. Therefore, the sliding directions of the first reciprocating lead screw 3511 and the second reciprocating lead screw 3521 are also opposite. When the first reciprocating lead screw 3511 drives the pushing disk 3512 to slide towards the conveying disk 1, the second reciprocating lead screw 3521 will drive the receiving disk 3522 to slide in the opposite direction of the conveying disk 1. Moreover, when the conveying disk 1 rotates 90 degrees, the first reciprocating lead screw 3511 and the second reciprocating lead screw 3521 complete a round trip, which can ensure that the four notches in the conveying disk 1 can continuously perform the closed-loop of conveying - separating - taking out - conveying.
