Description

Disc bale plucker

Technical Field

The utility model relates to a spinning field, concretely relates to disc bale plucker.

Background

The cotton yarn used in the textile industry is made of cotton fiber after being processed by a spinning process. In the process, firstly, a bale plucker is used for grabbing cotton bundles and cotton blocks from bundled cotton raw materials, and then the cotton bundles and the cotton blocks are conveyed to a subsequent machine through a negative pressure pipeline for processing and production of the next procedure. Existing pluckers are generally classified into linear reciprocating pluckers and disc pluckers. Among them, the disc type plucker is most widely used because of small occupied space.

The cotton bale is generally manually fed into the annular bin, and the cotton is different in height at different positions. The beater on the cotton suction cover is used for opening the cotton bale and grabbing cotton, the beater generally ascends and descends gradually along with the rotation of the cotton suction cover in the annular bin, and the beater needs to rotate step by step even if the beater cannot contact the cotton suction cover and the beater on the path until the beater descends to the surface of the cotton. Another convenience is that in some positions, the cotton bale has a certain tightness due to the high surface of the cotton bale, so that a beater can grab cotton balls with large balls which are not fully loosened or can be wound to death in the rotating process, and therefore, the cotton grabbing efficiency is low and the cotton balls are not fully loosened.
