Description

Technical Field

[0001] This utility model relates to the field of silk production equipment technology, and in particular to a device for stripping silkworm cocoons from silkworm pupae. Background Technology

[0002] Patent publication number CN222923328U discloses a silkworm pupa and silkworm cocoon peeling device, including a rotating shaft. Each end of the rotating shaft is rotatably connected to a mounting block. Two mirror-symmetrical countersunk holes are horizontally penetrating the sides of both mounting blocks. Multiple equidistantly distributed stripping rake teeth are radially fixed to the outer edge of the rotating shaft. Each end of the rotating shaft has a return stop, each movably connected to a mounting block. Each of the two mounting blocks has a limiting member connected to the rotating shaft on its outer side. By movably connecting the rotating shaft between the two mounting blocks using the return stop and fixing multiple equidistantly distributed stripping rake teeth on the rotating shaft, the device peels away the cocoon skin and some thin outer layers of the silkworm cocoons wrapped around the stripping belt. This prevents the cocoon skin wrapped around the stripping belt from being too thick and causing jamming. The rotating shaft can automatically rotate according to the thickness of the cocoon skin wrapped around the stripping belt, automatically adjusting the angle of the stripping rake teeth so that the stripping rake teeth are always in contact with the cocoon skin.

[0003] However, the stripping rake teeth in this patent are fixedly connected to the rotating shaft, making it impossible to replace them with stripping rake teeth of different models and materials. Utility Model Content

[0011] As a further description of the above technical solution: the air blowing component includes an air inlet pipe fixed to the lower edge of the rotating shaft, a wind hood fixedly connected to the bottom surface of the air inlet pipe, a dustproof net fixedly connected to the bottom of the wind hood, a fan fixedly connected inside the wind hood, a conical groove communicating with the arc-shaped groove is opened inside the rotating shaft, the air inlet pipe is communicating with the conical groove, a plurality of first air holes are opened on the bottom surface of the arc-shaped plate, and a plurality of second air holes communicating with the first air holes are opened inside the stripping rake toothed rack.

[0013] 2. Compared with existing technologies, this silkworm pupa and silkworm cocoon peeling device effectively solves the problem of entanglement and blockage by integrating an airflow cleaning and buffer locking mechanism, and improves the peeling quality and stability. The air blowing component set at the lower edge of the rotating shaft uses a fan to generate airflow. The airflow passes through the air inlet pipe and the conical groove inside the rotating shaft, and finally blows out from the first air hole at the bottom of the arc plate and the second air hole inside the rake tooth. This design forms a continuous downward airflow while the rake tooth is peeling, which can promptly blow away the peeled cocoon shell debris and fibers, preventing them from accumulating and entangled at the root of the rake tooth or in the gap of the rotating shaft. This fundamentally avoids jamming failures caused by blockage and ensures the continuity and cleanliness of the peeling process. In addition, the rotation damper and the second spring set at the connection between the support base and the rotating shaft constitute a buffer, which can effectively absorb the radial impact and vibration generated during the peeling process, preventing the rotating shaft from violently jumping or being damaged due to excessive instantaneous resistance.

[0018] Working principle: In use, the automatic peeling device is connected to the cocoon peeling machine of the external inspection agency using the mounting holes and fixing bolts on the support base 1. This ensures that the teeth of the peeling rake 7 are tangent to the cocoon skin on the peeling belt. When peeling is required, the peeling rake 7 automatically flips backward according to the thickness of the cocoon skin on the peeling belt. The arc-shaped block moves within the arc-shaped groove of the mounting block, simultaneously compressing the second spring. During compression, the second spring applies a reverse thrust, ensuring that the peeling rake 7 remains in contact with the cocoon skin on the peeling belt. Simultaneously, the fan 23 blows air into the conical groove 13, drawing in external air. After passing through the dustproof net 22, the air enters the conical groove 13 through the air inlet pipe 8. The cavity inside the conical groove 13 enters the stripping rake teeth 7 through the first and second air holes. Then, air is blown onto the silk through the second air hole, blowing away the stripped cocoon shell debris and fibers, preventing them from accumulating or getting tangled at the root of the rake teeth or in the gaps of the rotating shaft 12. This fundamentally avoids jamming caused by blockage and ensures the continuity and cleanliness of the stripping process. When not in use, pull the pull block 2 outward. The pull block 2 retracts the positioning block 14 into the countersunk hole 16 through the pull rod 17. At the same time, the first spring 15 is compressed, and then the lever... 3. Rotate the pivot 12 to align the positioning block 14 with the positioning groove of the fixing block 4. Then release the pull block 2. The compressed first spring 15 pushes the positioning block 14 from the countersunk hole 16 into the positioning groove. At the same time, the second spring is compressed. When used again, pull the pull block 2, and the first spring 15 is compressed, causing the positioning block 14 to leave the positioning groove. Then the compressed second spring returns to its original position. When the second spring returns to its original position, the pivot 12 rotates. The damper 20 causes the pivot 12 to rotate slowly, so that the stripping rake tooth 7 fits against the silk. When stripping is required... When replacing the rake tooth 7, rotate bolt 27. When bolt 27 rotates, the trapezoidal block 25 is pulled out from the trapezoidal groove 24 and put into the storage groove 26. Then, the arc plate 6 together with the stripping rake tooth 7 is taken out from the arc groove 5 through the first support block 10. Then, the arc plate 6 on the bottom surface of the stripping rake tooth 7 to be used is installed into the arc groove 5. Then rotate bolt 27. Bolt 27 pushes the trapezoidal block 25 out from the storage groove 26 and into the trapezoidal groove 24. Under the inclined guide and pressure of the trapezoidal block 25 and the trapezoidal groove 24, the arc plate 6 is firmly pressed into the arc groove.
