Problems solved by technology
[0002] At present, the centrifugal fan used in the automatic winding machine of the textile industry is mainly a backward-curved centrifugal fan impeller with arc-shaped blades. When the broken end of the thread is sucked into the impeller blade channel, it is easy to cause flower hanging and cotton accumulation, resulting in the disadvantages of low fan efficiency, high energy consumption, easy vibration, and difficult maintenance.

The invention relates to an energy-saving draught fan impeller of an automatic winder. The energy-saving draught fan impeller comprises an arc wheel cover (1), a flat and straight wheel disc (2), a shaft disc (2) and a plurality of blades (4). The arc wheel cover (1) and the flat and straight wheel disc (2) are arranged front and back. The blades (4) are evenly distributed between the arc wheel cover (1) and the flat and straight wheel disc (2) and are in a back-bent type flat and straight plate shape. According to the energy-saving draught fan impeller of the automatic winder, the requirement for negative pressure and fracture end cotton absorbing in the automatic winder procedure of the spinning industry is met, the back-bent type flat and straight plate shape blade structure is adopted, and the energy-saving draught fan impeller has the advantages of being smooth in runner, not prone to blockage, efficient, capable of saving energy, easy to maintain, convenient to install, stable in running and the like.
Description
technical field [0001] The invention relates to an energy-saving fan impeller for an automatic winder. The fan is suitable for generating negative pressure in the automatic winder and is a centrifugal fan for sucking and collecting cotton through a flute mouth after the yarn breaks, and belongs to the technical field of textile machinery. Background technique [0002] At present, the centrifugal fans used for automatic winders in the textile industry are mainly backward-curved centrifugal fan impellers with arc-shaped blades. When the broken end of the thread is sucked into the impeller blade channel, it is easy to cause flower hanging and cotton accumulation, resulting in the disadvantages of low fan efficiency, high energy consumption, easy vibration, and difficult maintenance. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide an energy-saving fan impeller for an automatic winder, which meets the re...
