Description

Seed cotton foreign fiber sorting machine

technical field

The utility model relates to a mechanical device for sorting foreign fiber impurities in seed cotton, which is mainly suitable for cotton processing enterprises and belongs to the technical field of cotton processing machinery.

Background technique

Foreign fibers in cotton (commonly known as "three silks") are non-cotton fibers contained in seed cotton or lint, mainly including: plastic film, nylon silk, hemp rope, colored rags, wool ends, polypropylene silk, animal hair, poultry Pinna etc. These foreign fibers are mainly mixed into raw cotton during the process of cotton planting, picking, and distribution. After ginning and spinning, the three-filament particles become finer and finer, and are mixed with cotton fibers, which is difficult to clean. When weaving with raw cotton containing three-filament particles, it is very easy to cause spun yarn breakage, which greatly increases cloth surface defects. Moreover, due to different coloring properties during printing and dyeing, color defects are easily formed and exposed to the cloth surface, seriously affecting the appearance quality of the cloth. At present, there are two main methods for removing foreign fibers in seed cotton in ginning plants: one is to employ a large number of manpower for sorting, and the other is to use winding rollers for mechanical separation. These methods can remove part of the three filaments in the seed cotton, but the labor consumption is too much, the cost is too high, and the effect is not ideal enough.

Contents of the invention

The technical solution of the utility model is: a cotton inlet is provided on the machine body, and a high-speed rotating soft extra miscellaneous roller is installed in the box below the cotton inlet. A number of thorns are regularly arranged on the circumference, and two adjacent rows of thorns are staggered alternately. There is a projecting roller under the soft special roller. The diameter of the projecting roller is larger than that of the soft special roller. The arrangement of the thorns is consistent with The soft special roller is the same, the outer periphery of the projecting roller is provided with deflectors, a cotton baffle is provided above the projecting roller, a diffusion box is provided on the right, and the left lower side wall of the diffusion box adjacent to the projecting roller is provided with a supplementary air port , a wind pressure regulator is set on the upper right side wall, the lower opening of the diffuser box is gradually shrunk and then connected with a closed air valve, and the upper mouth is gradually shrunk to form an air suction port, the rotation of the soft special roller, the projecting roller and the closed air valve are all controlled by the driver drive.

When working, the seed cotton is fed into the box from the cotton inlet and falls to the soft special roller, and the high-speed rotating soft special roller feeds the cotton to the lower ejection roller at the same time. The longer soft impurities are entangled, and the entangled impurities are regularly removed manually. The seed cotton is driven by the ejection roller to run to the front, and is thrown along the deflector under the action of inertial centrifugal force, and is supplemented by the wind under the combined action of the air supply port below. Throwing it into the diffusion box, taking advantage of the different physical characteristics of the specific gravity of the seed cotton and foreign fibers, the heavier seed cotton shoots the wall and then settles down along the inner wall of the diffusion box until it falls into the closed air valve and is discharged out of the machine, and is sent to the subsequent process; At the same time, the plastic film, poultry feathers, animal hair heterogeneous fibers and fine dust entering the diffuser box rise with the wind due to their light specific gravity, and are discharged out of the machine with the airflow by the suction of the upper part of the diffuser box, so as to achieve the removal of seed cotton The effect of various foreign fiber impurities in the

The utility model has the advantages of:

1. In this utility model, because the thorns of the soft special roller and the ejection roller adopt the arrangement of two adjacent rows of thorns alternately staggered, the cleaning effect of the thorns on the seed cotton is more uniform, and the cleaning effect on the nylon yarn, polypropylene yarn, hemp rope, etc. The winding of longer soft impurities is also more thorough.

2. The utility model is provided with a supplementary air port on the lower left side wall of the diffusion box, and a pressure regulator is provided on the upper right side wall, and the air pressure, flow velocity and flow direction in the diffusion box are jointly controlled by the lower supplementary air and the upper pressure adjustment, so that the plastic film, poultry Feathers, animal hair and other light-weight foreign fibers and fine dust are fully separated from the seed cotton to improve the removal rate of impurities.

3. The utility model has the advantages of simple structure, low equipment cost, less power consumption, and easy operation and control.
