Apparatus for producing bagworm silk thread
A recently granted patent (Publication Number: US11877567B2) discloses an apparatus designed for producing bagworm silk thread. The apparatus includes a movable rail that can hold a bagworm fixed by a fixator, with the rail having a width smaller than the maximum width between the bagworm's legs. Additionally, the apparatus features peeling containers storing a solution or vapor for peeling the spun silk thread from the rail, along with a collection device to gather the peeled silk thread. Furthermore, thread hooks are included to alter the reeling direction of the silk thread, with the rail being loop-shaped or circular in some embodiments.
Moreover, the apparatus is equipped with a bobbin on the collection device to reel in the collected silk thread, featuring concavities and convexities along the wind-up direction to receive the thread. The patent also details the synchronous rotation of the movable rail and collection device, ensuring efficient silk thread production. Overall, the apparatus offers a comprehensive solution for producing bagworm silk thread, incorporating innovative features like peeling containers, thread hooks, and synchronized rotation for enhanced functionality and productivity in silk thread manufacturing processes.
