Description

Sawtooth type ginned cotton cleaning machine

Technical Field

The utility model belongs to the technical field of cotton processing equipment, and particularly relates to a sawtooth type ginned cotton cleaning machine.

Background

With the development of the mechanical cotton picking process, the raw cotton has high impurity content, and becomes the biggest problem facing cotton processing enterprises. After the seed cotton is cleaned by the pretreatment unit and the saw gin, about 60 percent of sterile seeds and about 10 percent of impurities still remain in the ginned cotton and cannot be removed. In addition, in the whole process of ginning, some defects such as broken seeds, neps and rope yarns are always generated, the appearance form and the color degree of ginned cotton are seriously influenced by impurities and defects in ginned cotton, and the grade of ginned cotton is influenced, so that the appearance form of ginned cotton can be changed by cleaning ginned cotton, most of large-particle impurities in ginned cotton are removed, the grade or the preservation grade of ginned cotton can be improved, and considerable economic benefits can be brought to cotton processing enterprises.

The traditional lint cleaner has the advantages that as the lint feeding device is arranged between the lint collecting dust cage and the saw blade roller, the damage to the treatment capacity and the cotton fibers is affected to a certain extent when lint is processed, and the improvement of the treatment capacity of the lint cleaner is greatly affected due to the limitation of the lint feeding plate and the lint feeding roller; secondly, due to the holding of the cotton feeding plate and the cotton feeding roller, when the saw teeth hook and pull the cotton fibers, the cotton fibers are easy to break or damage, the breaking specific strength of the cotton fibers is affected, the linter rate is increased, and the quality and grade of the ginned cotton are reduced; thirdly, due to the extrusion of the cotton feeding plate and the cotton feeding roller, impurities and defects are entangled with cotton fibers more tightly, which is not beneficial to the carding and impurity removal of saw teeth and affects the impurity removal effect. This structure also complicates the structure of the machine and increases its bulk.

Further improved lint cleaning machines, such as the patent application of Chinese patent publication No. CN111379052A, named cotton layer conveying mechanism and lint cleaning machine, are provided with two stripping rollers and two feeding rollers between the dust collecting cage and the saw blade roller, although no more cotton feeding plate is reserved between the dust collecting cage and the saw blade roller.

The working principle of the utility model is as follows: the induced draft fan attracts lint from the previous procedure through dust cage induced air lugs 13 at two sides of the dust cage 2, and the lint enters a lint channel of the dust cage part through lint inlet 14, and as the lint channel is a sealed space, the lint is gradually adsorbed on the net surface of the dust cage 2 and rotates along with the dust cage 2, wherein a part of fine impurities and dust enter the inner space of the dust cage 2 through dust cage meshes, and are discharged along with induced air through dust cage induced air lugs 13 at two sides of the dust cage 2; the cotton layer adsorbed on the net surface of the cotton collecting dust cage 2 is hooked and pulled by a rack on the rotating saw blade roller 3 in the process of rotating the cotton collecting dust cage 2 to the minimum gap between the cotton collecting dust cage 2 and the saw blade roller 3, and the cotton fibers hooked and pulled by the rack rotate along with the saw blade roller 3, then are blocked and pressed by the cotton carding plate 5, and the cotton fibers which are not hooked by saw teeth and are attached to the surface of the saw blade roller 3 are hooked and pulled again; the hooked fiber rotates at a high speed along with the saw blade roller 3, because the large particle defects such as sterile seeds, seed scraps, leaf scraps and the like are larger than the specific gravity of cotton fiber, the fiber is suspended on the outer layer of the air flow layer of the saw blade roller 3 under the action of centrifugal force, when the fiber passes through a plurality of impurity discharging cutters 6, the air flow, impurities and free cotton fiber on the outer layer are cut by the edges of the impurity discharging cutters, are rapidly discharged along the upper surface of the impurity discharging cutters 6 and fall into an impurity sucking box 12; the cotton fibers cleaned by the impurity removing cutters 6 rotate to the brush roller 4 along with the saw blade roller 3, enter the lint path through the lint outlet 15 under the blowing and brushing action of the brush roller 4, and are conveyed to the aggregate cotton under the suction of the aggregate cotton induced air.

It should be noted that, when the net surface of the cotton collecting cage 2 is free from free fibers which are not hooked and pulled by the saw blade roller 3, and the cotton collecting cage 2 rotates and enters the rear sealing cavity provided with the net surface cleaning device, the brush bristles on the small brush roller 16 not only brush the free fibers which are not hooked and pulled by the saw blade roller 3 on the net surface of the cotton collecting cage 2, but also brush the free fibers into the meshes of the cotton collecting cage 2, so that the impurities such as broken seeds, cotton leaves and the like stored in the meshes are sucked away by the dust brushes into the cotton collecting cage 2, and the dust cage induced air ears 13 on two sides of the cotton collecting cage 2 are sucked away by the induced air, thereby ensuring the ventilation effect of the net surface and removing part of the impurities.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made hereto without departing from the spirit and the principles of the utility model.
