Opening and cleaning method for axial flow opener for opening picking or blowing carding process and special composite beater device thereof

Abstract

The invention provides an opening and cleaning method for an axial flow opener for opening picking or blowing carding process, and a special composite beater device. The method comprises the step that a cotton block to be opened makes spiral movement along beaters under common action of the beaters and air flow after the cotton block to be opened is fed into a beater chamber. The method is characterized in that the cotton block is subjected to opening and cleaning in different beating modes in turns when the cotton block makes spiral movement from a cotton inlet to a cotton outlet. The special composite beater device comprises beater cylinders, and is characterized in that the beater cylinders are provided with a blade region, a bar-shaped brad region and a V-shaped brad region in sequence from the inlet end to the outlet end. A reducing mode that the beater outer diameter is reduced from the inlet to the outlet in turns is adopted, so distances between beaters and grid bars are increased from the inlet to the outlet in turns to adapt to the condition that the cotton block is gradually opened and expanded in the forwarding process. The method has reasonable opening mode, high cleaning efficiency and fiber destruction prevention, and achieves the effect of developing strong points and avoiding weak points compared with the prior art.

Description

The method of opening and removing impurities and its special compound beating device for axial flow openers in the process of opening and cleaning cotton or blowing and carding (1) Technical field The invention relates to the field of textile machinery, in particular to an opening and cleaning method for an axial-flow opener in a blowing-carding process and a special compound beating device thereof. (2) Background technology The cotton opener is one of the main equipment in the process of opening and cleaning or blowing and carding. It will loosen and remove impurities from the delivered cotton block to meet the needs of the next spinning process. At present, there are mainly two types of cotton openers: one is the "free opening type" in which raw cotton is fed into the beating chamber by airflow, such as six-roller openers, axial flow openers, etc. It is generally used for preliminary opening and impurity removal of fibers. The other type is the "holding and opening t...
