Description

Technical Field

[0001] This utility model relates to the field of down processing equipment, and in particular to a high-efficiency multi-stage down screening machine. Background Technology

[0002] Common problems in existing down processing technologies include low feather separation efficiency, poor adaptability to different types of down, and significant damage to the down during processing. This often leads to reduced down utilization, compromised down quality after processing, and a greater environmental burden during processing. With the development of the textile industry and increasing market demand, higher requirements are being placed on down processing equipment. There is a need for feather separation equipment that can improve separation efficiency, ensure down quality, and be environmentally friendly to meet the needs of industrial production.

[0003] Patent document CN117401640A discloses a down sifting machine, including a main body and a down removal mechanism comprising: a bidirectional working motor mounted above a support frame; a telescopic rod movably connected to the outside of the bidirectional working motor; a connecting frame connected to the top of the telescopic rod; a mounting sleeve mounted on the outside of the connecting frame; and a down removal sleeve connected to the mounting sleeve and fitted onto the outside of the sifting rod. This invention utilizes the bidirectional working motor to control the telescopic rod's extension and retraction. The connecting frame at the top of the telescopic rod moves synchronously, pushing outwards. This causes the mounting sleeve to move synchronously, moving the down removal sleeve across the surface of the sifting rod and removing the down adhering to its surface, thus preventing excessive down buildup.
