Description

Technical Field

[0001] The utility model relates to the technical field of cotton processing equipment, in particular to an airflow type parallel double-toothed roller lint cleaning machine. Background Art

[0002] During the cotton processing process, it has to go through multiple cleaning processes. Impurities must also be cleaned during the lint processing stage. The lint impurity cleaning machine uses mechanical methods, airflow methods or pneumatic methods to separate impurities in the lint. Among these methods, the most widely used is the mechanical method. The mechanical method uses a sawtooth roller to comb the lint. After the lint is combed, the distance between the cotton fibers is enlarged, and the connection between the fibers and impurities is very loose, thereby improving the cleaning effect. The dust is separated due to the centrifugal force of the sawtooth roller and the gravity of the dust itself. At present, due to the widespread use of machine-picked cotton, the impurities in seed cotton have increased significantly, bringing greater challenges to the work of cleaning impurities. In the lint cleaning stage, a large number of large impurities, infertile seeds, small cotton seeds, shriveled seeds, cotton stalks and broken cotton leaves are also carried. Since the serrated roller is wound on the roller by a sawtooth bar, the height of the sawtooth bar is relatively small, the sawtooth teeth of the sawtooth bar are also relatively small, and the sawtooth bars are closely arranged, in the process of cleaning impurities, a large number of large impurities, infertile seeds, small cotton seeds, shriveled seeds, cotton stalks and broken cotton leaves are stuck between the saw teeth and are difficult to fall off, which seriously affects the cleaning effect, and it is difficult to clean up these impurities stuck between the saw teeth, which seriously affects the processing quality of lint cotton. Therefore, an airflow-type parallel double-serrated roller lint cleaning machine is provided, which adopts a parallel double-serrated roller and an air impurity removal knife structure, which can ensure the lint length grade and improve the lint quality while ensuring the impurity cleaning quality. Utility Model Content

[0003] The problem to be solved by the utility model is to provide an airflow-type parallel double-serrated roller lint cleaning machine. The parallel double-serrated roller structure can be used to select one or two passes of lint cleaning according to the impurity content of the lint by rotating the reversing plate, thereby achieving good impurity removal effect and high efficiency. In addition, since there is no holding hook pulling process of the existing serrated lint cleaning machine during the airflow feeding process, the cotton fibers are less damaged. The utility model is suitable for cleaning long-staple lint and can ensure the lint grade of the lint while ensuring the impurity quality, thereby improving the quality of the lint.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

The windshield plate 6 can prevent excessive airflow from passing through the serrated roller to ensure that the lint cotton is evenly transported after entering the cleaning chamber. An arc-shaped cotton scraper plate 9 is arranged directly below the first serrated roller 18. The arc-shaped cotton scraper plate 9 is used to prevent the lint cotton fibers from returning to cotton so that the cleaned lint cotton can be smoothly discharged through the lint cotton outlet.

[0020] Working principle: Taking the cleaning process of lint cotton in the first cleaning chamber 10 as an example, the fluffy lint cotton enters the first cleaning chamber 10 from the dual-channel cotton transport tube 1 from the first cotton inlet 3, and is combed by the first serrated roller 18. The gaps between the lint cotton fibers are enlarged, and the fibers are loosely connected to the impurities, so that the large impurities, infertile seeds, small cotton seeds, shriveled seeds, cotton stalks and broken cotton leaves in the cotton fibers are combed out. Since there is a relatively large gap between the saw blades in the serrated roller, impurities are not easily stuck on the saw teeth. The impurities fall into the impurity removal auger 17 under the action of the air impurity removal knife 12 and gravity, and the finer dust is separated by the centrifugal force of the serrated roller and the gravity of the dust. When the cotton fibers on the serrated roller pass through the sharp corners of the scraper plate 9, they are peeled off from the saw teeth by the scraper plate 9, and the lint cotton is sent out through the first cotton outlet 8. Large impurities, infertile seeds, small cotton seeds, shriveled seeds, cotton stalks and broken cotton leaves carried in the lint can be cleaned out before the sawtooth lint cleaning machine, which not only provides protection for the sawtooth lint cleaning machine, but also ensures the quality of lint processing, and can greatly improve the grade quality of lint.

[0021] Example 2: Example 2 Compared with Example 1, the internal structure of the first impurity cleaning chamber 10 and the internal structure of the second impurity cleaning chamber 16 are the same and symmetrically distributed. The difference is that in Example 2, the first impurity cleaning chamber 10 and the second impurity cleaning chamber 16 have a common cotton outlet which is a lint cotton bend 19. After cleaning, the lint cotton flows to the common cotton conveying pipeline 20, and the impurity removal auger is changed from the common impurity removal auger 17 to the impurity removal augers in their respective impurity cleaning chambers.
