Description

Technical Field

[0001] This utility model relates to the field of down processing technology, and in particular to a down suction device for down processing. Background Technology

[0002] Down is a mixture of "feathers" and "down." Feathers are the feathers that provide support and allow the down to quickly spring back; while down is the down cluster, which is the core of the down and its value. A down cluster is a three-dimensional spherical structure, composed of a core and many radiating down fibers, similar to a dandelion. Down fibers are made up of thousands of tiny, hollow scales.

[0003] Down production and processing workshops typically have down-absorbing devices to absorb down that has fallen and remained in the workshop environment, keeping the environment clean while also allowing the scattered down to be recycled.

[0004] Patent document CN213487154U discloses a down-collecting device for down processing, relating to the field of down-collecting devices. It addresses the problem of pipe blockage, particularly at the air outlet, that occurs in existing down-collecting devices after prolonged use. An AC motor is fixedly mounted on the outer surface of one side of the down-collecting chamber. One end of the AC motor's rotating shaft is fixedly connected to the central axis of one end face of a separating rotating drum. The separating rotating drum is located inside the down-collecting chamber, and its other end is rotatably mounted inside a rotating drum seat. The rotating drum seat is fixedly mounted on the inner wall of one side of the down-collecting chamber. A first separating brush and a third separating brush are fixedly mounted on the upper and lower surfaces inside the down-collecting chamber, respectively.

[0005] As in the prior art of the aforementioned patent, during the down suction process, although the down does not get clogged at the feed end of the down suction box, the air suction end inside the box is located at the top of the box, while the collection drawer is located at the bottom of the box. In addition, the rotating drum inside the box affects the airflow inside the box, so the down cannot stay stably inside the collection drawer and will fly around inside the box, thus affecting the stability of the down suction process.
