This case relates to a flat cocoon production and naked pupa collection device, including a body, a rotating shaft and a collection device.The main body is a closed tubular structure, which has a first side, a second side and a continuous surface. The first side and the second side are relatively arranged, and the continuous surface is connected between the first side and the second side to jointly form a closed tubular structure.The rotating shaft extends from the first side and the second side of the body.The collecting device is correspondingly arranged under the body.The continuous surface of the body has a rough surface, so that the mature silkworms can easily cling to the continuous surface, and the system rotates slowly with the axis of rotation, so that the mature silkworms are not easy to stack and cover each other when climbing and spinning on the continuous surface, and can produce a plane cocoon of good quality, and the collection device under it adopts a slope design, which can effectively collect the naked silkworms when they start to pupate and fall off Pupa.本案係關於一種平面繭生產及裸蛹收集裝置，包括本體、轉軸及收集裝置。本體為封閉式筒狀結構，具有第一側面、第二側面及連續表面，第一側面與第二側面係呈相對設置，且連續表面連接於第一側面與第二側面之間，以共同構成封閉式筒狀結構。轉軸係自本體之第一側面及第二側面延伸而出。收集裝置係對應設置於本體之下方。本體之連續表面係具有粗糙表面，以使熟蠶易於攀附於連續表面上，且本體係以轉軸為軸心而緩慢旋轉，以使熟蠶於連續表面上攀爬及吐絲時不易相互堆疊包覆，並可營出品質優良之平面繭，且其下之收集裝置採斜面設計，可於熟蠶開始化蛹脫落時有效率的收集裸蛹。
