Progressive axial flow scutcher

Abstract

The invention discloses a progressive axial flow scutcher which comprises a machine shell, a cotton collecting inlet is formed in the top of the machine shell, a rotary nozzle is formed in the position where the cotton collecting inlet is connected with an inner cavity of the machine shell, the rotary nozzle is surrounded by a large dust cage, and an outlet in the bottom of the large dust cage is connected with a scutcher assembly. The scutcher assembly comprises a cotton inlet, a first beater of a blade type structure and a second beater of a sawtooth type structure. The front side of the lower end of the first beater is provided with a first dust removal cutter group, and the rear side of the lower end of the first beater is provided with a second dust removal cutter group; the front side of the lower end of the second beater is provided with a third dust-removing cutter group, the rear side of the lower end is provided with a fourth dust-removing cutter group, and a second carding roller is arranged right below the lower end; and a third carding roller is mounted between the second dust removal cutter group and the third dust removal cutter group. The machine-harvested cotton impurity removal device has the advantages of high impurity removal rate, low cotton falling and no damage to fibers, and can effectively overcome the technical bottleneck that high fine impurities of machine-harvested cotton are difficult to remove, so that the subsequent spinning quality is influenced.

Description

technical field [0001] The invention relates to the technical field of textile equipment, and more specifically, relates to a progressive axial flow cleaning machine. Background technique [0002] In the past, cotton harvesting was mainly manual, but today, due to labor shortage and high labor costs, it has been replaced by machine picking cotton. However, because machine-picked cotton cannot be harvested selectively, graded and graded, the harvested cotton is not only uneven in maturity, fiber length and quality, but also has neps and immature cotton caused by infertile seed cotton. Mature short fibers increase, especially impurities such as cotton leaves and fine impurities are extremely high. Therefore, the original cotton cleaning machine, which was limited to removing large impurities, has been unable to meet the needs of machine-picked cotton for removing impurities. Its main disadvantages are: [0003] 1. Unable to remove impurities inside cotton. The cotton feedi...

Problems solved by technology

Therefore, there is nothing that can be done to remove the finer impurities contained in machine-picked cotton

[0005] 3. The thugs of the above two machines are nothing more than blades, iron rods or steel claws. The blades are longer, and the distance between them and the dust removal knife is relatively large, so it is difficult to remove fine impurities.

At the same time, both of the above two machines use triangular rods for dust removal. The overall length is relatively short, generally 25-30mm. Sophistication has limited effect

[0006] Therefore, how to effectively overcome the technical bottleneck of machine-picked cotton, which is difficult to remove high-fine impurities and affect the quality of subsequent spinning, is a subject that those skilled in the art need to focus on.
