[0043] The 1# air-flow seed cotton impurity removal machine 2, the 2# air-flow seed cotton impurity removal machine 3 and the air-flow lint impurity removal machine 7 are different in that the impurity removal grid plate is arranged on the impurity removal port 74 to prevent the blowing of lint.

[0044] The packing machine 9 is connected with the baling machine 91.

[0045] The long-staple cotton processing system process of the present application comprises the following steps:

[0046] 1) Seed cotton feeding and impurity removing process: the seed cotton is sent into the heavy impurity separator 1 by the flower feeder for preliminary impurity separation, and then is further impurity removed by the 1# air flow seed cotton impurity removing machine 2 and the 2# air flow seed cotton impurity removing machine 3 connected in series, and then is further impurity removed by the three-roller separator 4;

[0047] 2) Ginning process: the seed cotton after the above impurity removing process falls into the cotton collecting tank 41, and then is sent into the seed cotton separator 5 through the cotton conveying pipeline by the suction fan 101 to separate the cotton fiber from the cotton seed, and the cotton fiber separated from the cotton seed is conveyed to each gin 6 after being distributed by the distribution auger from the discharge port of the seed cotton separator 5, and the cotton fiber is ginned in the gin 6, and the high-pressure atomizer 61 sprays the seed cotton at high pressure before the cotton fiber enters the gin 6, so that the moisture content of the cotton fiber reaches 8%, and the ginning quality is improved;

[0048] 3) Lint cleaning process: the ginned lint is blown into the air flow lint cleaning machine 7 by the positive pressure fan 103 for lint cleaning;

[0049] 4) Baling process: the lint after the air flow lint cleaning is sucked into the cotton collector 8 by the suction fan 2 104 to further remove dust and small impurities, and the lint is layered in the cotton collector 8 and then falls into the baling machine 9 for baling, and the baled lint is automatically sent to the subsequent link after being formed into bales by the baling machine 91.

[0050] The airflow lint cleaner 7 mainly utilizes the air-cotton mixed flow to be sent into the cylindrical shell 701 at a certain speed, changes the direction of the lint movement rapidly, utilizes the larger centrifugal force of the impurity unit density, so that the impurities are separated from the cotton fibers and discharged from the mesh holes of the impurity discharge screen plate 75 on the impurity discharge port 74, and the lint is cleaned. The cleaning efficiency depends on the size of the wind speed when the air-cotton mixed flow is blown. In the case of constant output of the gin stand, the higher the wind speed, the thinner the lint layer on the lint conveying roller 73, and the easier the impurities are cleaned out. The speed of the lint conveying roller 73 is adjustable and matches the blowing speed of the cotton fibers; during cleaning, firstly, the lint is blown by the positive pressure wind to enter the cylindrical shell 701 through the lint inlet channel 71 and the lint inlet port 702 and falls on the lint conveying roller 73. In this process, due to the different specific gravity of the impurities and the cotton fibers, a part of the impurities can be blown out of the impurity discharge port 74 by the positive pressure wind to achieve the cleaning effect; (2) the motor drives the lint conveying roller 73 to rotate, and the lint conveying roller 73 drives the closed wind scraper 731 to rotate from one side of the lint inlet port 702 to the other side of the lint outlet port 703. In this process, part of the impurities in the lint on the lint conveying roller 73 are separated from the cotton fibers and discharged from the mesh holes of the corresponding impurity discharge screen plate 75 on the top of the cylindrical shell 701, further achieving the cleaning of the lint. During the conveying of the lint, the closed wind scraper 731 can drive the soft scraper 732 to scrape and clean the inside of the cylindrical shell 701, ensuring the smoothness of the mesh holes on the corresponding impurity discharge screen plate 75. In addition, during the rotation of the lint conveying roller 73, the soft scraper 732 is in contact with the inner wall of the cylindrical shell 701 away from the edge of the closed wind scraper 731. The closed wind scraper 731 cooperates with the soft scraper 732 to seal the wind entering the cylindrical shell 701 to prevent the wind from flowing downward into the lint outlet port 703. Finally, the lint cleaned completely is discharged from the lint outlet port 703.

[0051] Example 2, refer to Figure 9 As a further optimized design of example 1, the fiber opening tooth roller 710 is arranged at the tail of the lint inlet channel 71. The fiber opening tooth roller 710 includes an eccentric roller 711 which is installed in parallel with the lint conveying roller 73. The eccentric roller 711 is uniformly provided with fiber opening teeth 712 on the top along the length direction. A plurality of buffer springs 713 are installed on one side of the eccentric roller 711. The eccentric roller 711 and the lint conveying roller 73 are equal in axial length and are matched with the axial length of the cylindrical shell 701. The fiber opening tooth roller 710 cooperates with the lint conveying roller 73 to thin the cotton fibers entering the cylindrical shell 701 through the lint inlet channel 71, clean the impurities in the cotton fibers, and further improve the cleaning effect. The vibration of the buffer springs 713 can further improve the degree of disorder of the cotton at the lint inlet port 702, effectively improving the cleaning effect. The plurality of buffer springs 713 are symmetrically installed near the two ends of the eccentric roller 711.
