Anti-suckback high-efficiency ginning machine

Abstract

The invention discloses a back-suction-preventing high-efficiency embossing machine. An air inlet (14) and an air quantity regulating device (16) are arranged on one end or two ends of a brush roll (2) of the embossing machine, and air outlets (11) among brush strips or cotton brushing plates are formed in the circumference of the roller of the brush roll (2); an impurity-removing combination comprises an impurity-removing lattice bar grid (4) and a lower impurity-removing stranding cage or an impurity-suction port (5), and is located on the outer side of the brush roll. According to the back-suction-preventing high-efficiency embossing machine disclosed by the invention, by means of changing the structure of the traditional roller, the roller under high-speed rotation not only has an air conveying function and an inertial centrifugal force, but also is free from a self back suction phenomenon, so that fibers and impurities locate at different positions of an air flow layer under the action of centrifugal force due to differences in self weight and connecting force, and are forced to be separated under the coordination of the impurity-removing combination, and moreover, the fibers can be prevented from being overflowed. Alternatively, by means of changing the traditional cotton supporting plate into the impurity-removing combination, the purpose of separating the fibers and the impurities can also be achieved by changing the air inlet position of the brush roll under the attraction of a proper quantity of air.

Description

technical field [0001] The invention relates to a cotton processing machine, in particular to a high-efficiency ginning machine which separates fibers or short fibers and impurities in seed cotton and has the function of preventing back-absorption. Background technique [0002] During cotton processing, the fibers in the seed cotton are separated from the seed cotton to form lint, and the linters on the cotton seeds are retained. The gin used should be suitable for all grades of seed cotton with a moisture content of less than 10% and preliminarily cleaned by a seed cotton cleaning machine. The working process of the existing cotton gin includes first-level cleaning of the seed cotton cleaned by the seed cotton cleaning machine, so that some impurities, especially large particles of impurities, and a small amount of seed cotton are also mixed under the action of gravity and centrifugal force. After repeating the above process, At the same time, the seed cotton is brushed on...

AI Technical Summary

Problems solved by technology

However, a problem that is difficult to solve in the current cotton gin is that there are multiple rotating rollers in different directions and some necessary accessories inside the cotton gin. Cotton seeds and sundries produce reflux, which affects the production efficiency of the cotton gin, is not conducive to the effective separation of fibers and impurities, and is easy to cause waste of effective fibers. Repeated cleaning and multiple separation operations are required, resulting in complex equipment, high input costs, and low efficiency.
