Embodiment 1

[0066] Such as Figure 4 Shown: the compound beater (1) of the axial flow opener suitable for the open-cleaning or blowing-carding process of the present invention consists of a cylindrical beater barrel (2) and a V-shaped angle nail ( 3), rod-shaped corner nails

[0067] (4), rectangular blade (5) and other components. Rectangular blades, rod-shaped corner nails, and V-shaped corner nails are installed in sequence from the inlet to the outlet, and are distributed on the outer surface of the beater barrel in the form of a spiral. From the inlet to the outlet, the diameter of the beater decreases in turn, that is, ΦD Figure 4a , 4b , 4c).

[0068] The opening and impurity removal process is as follows: after the opened cotton block is sent into the beater room, under the combined action of the beater and the air flow, it moves in a spiral line along the beater. The characteristic is that the cotton block moves from the cotton inlet to the cotton outlet. In the spiral movement, the...

Embodiment 2

[0070] Such as Figure 5 Shown: The difference between this embodiment and embodiment 1 is that the beater barrel (2) is in a cone structure, and the rectangular blade (5), rod-shaped corner nails (4), and V-shaped corner nails (3) are imported They are respectively installed in the direction of the outlet, and distributed on the outer surface of the hand barrel (2) in the form of a spiral. From the inlet to the outlet, the diameter of the beater decreases in turn, that is, ΦD Figure 5a , 5b , 5c).

[0071] The working process is the same as in Example 1.

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

(1) Technical field [0001] The invention relates to the field of textile machinery, in particular to a method for opening and removing impurities of an axial flow opener used in the process of opening and cleaning cotton or blowing-carding combined processes and a special composite beater device. (2) Background technology [0002] The opener is one of the main equipments in the open-cleaning or blowing-carding process. It opens and removes the transferred cotton lump to meet the needs of the next spinning process. [0003] At present, there are two main types of openers: one is the "free opener" in which raw cotton is fed into the beater room through airflow, such as six-roller openers and axial flow openers. It is generally used for preliminary opening and impurity removal of fibers. The other type is the "grip-opening type" in which the raw cotton is fed into the beater room via a feeding roller, such as a porcupine opener, a sawtooth opener, and a needle opener. Generally use...
