Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cotton ginning machines, in particular to a sawtooth cotton ginning machine. Background Art
[0002] Cotton ginning refers to the process of separating cotton fibers from cotton seeds. Through the ginning operation, impurities, short fibers and immature fibers are removed, and the length, strength and uniformity of the cotton fibers are increased, thereby improving the quality of the cotton and facilitating the subsequent textile processing of the cotton fibers.
[0003] The main structure of the current cotton gin is composed of components such as the feeding device, the sawtooth roller, the ribs, the impurity removal device, the transmission system and the discharge device. Its working principle is: cotton enters the cotton gin through the feeding device, and the cotton fibers are pulled off the cotton seeds under the interaction of the sawtooth roller and the ribs. At the same time, the impurity removal device removes impurities in the cotton, and the cleaning device cleans the cotton gin parts to ensure the continuous and efficient ginning. The separated cotton fibers are finally output through the discharge device.
[0004] However, during the use of the current cotton gin, the serrated roller rotates at a high speed in the gap between the two ribs. Therefore, the cotton is easily clumped into pieces and blocked in the gap between the two ribs. As the serrated roller rubs against the clumped cotton, a fire occurs in the cotton gin, which not only affects the normal operation of the cotton gin and reduces production efficiency, but also poses a great safety hazard.

[0007] The working principle of the utility model is as follows: when it is necessary to gin seed cotton, the cotton gin is first started, and then the cotton enters the machine body through the cotton inlet channel. As the main serrated roller and the auxiliary serrated roller rotate, the cotton fibers are hooked on the main serrated roller and the auxiliary serrated roller for separation. In this process, a pulley on a rotating shaft connected to a side of each ginning rib rotates to assist the movement of the cotton to prevent the cotton from clumping and blocking the gap between the ribs. The cotton fibers hooked on the main serrated roller and the auxiliary serrated roller are collected by a blowing and brushing assembly.
[0008] The beneficial effects of the utility model are: by arranging the rotating shaft and the pulley, the cotton is ensured to move smoothly during the cotton ginning process, and the cotton is prevented from clumping and blocking the ribs, thereby reducing the friction between the cotton and the equipment, reducing production interruptions and equipment failures caused by blockage, and improving the operating stability and production efficiency of the cotton gin.
[0009] Option 2, which is the preferred option of the basic option, the cotton brushing assembly includes two cotton discharge cavities, the cotton discharge cavities are connected to the machine body, and the machine body is rotatably connected with brush cylinder 1 and brush cylinder 2, the brush cylinder 1 and brush cylinder 2 are respectively located in the two cotton discharge cavities, one side of each of the cotton discharge cavities is respectively close to the main serrated roller and the auxiliary serrated roller, and one side of each of the cotton discharge cavities is provided with a cotton outlet, the rotation direction of the brush cylinder 1 and brush cylinder 2 is opposite to that of the main serrated roller and the auxiliary serrated roller; wind force is generated by the reverse high-speed rotation of brush cylinder 1 and brush cylinder 2, and under the combined action of blowing and brushing of the brush, all cotton fibers are separated to ensure efficient cotton ginning work.
[0010] Option three is a preferred option of option two. Each of the cotton discharge chambers is provided with a debris discharge adjustment plate on one side close to the main serrated roller and the auxiliary serrated roller. By providing the debris discharge adjustment plate, the size of the debris discharge port can be flexibly adjusted according to actual conditions to adapt to different cotton raw materials.
[0011] Option 4 is a preferred option of the basic option, in which a debris removal scraper is rotatably connected to the body, a debris removal chamber is provided in the body, the debris removal scraper is located in the debris removal chamber, the debris removal chamber is located on a side close to the main serrated roller and the brush roller, and a debris removal air flow channel is provided on one side of the debris removal chamber; by arranging the debris removal scraper and the debris removal chamber, impurities attached to the cotton fibers of the main serrated roller can be blocked and removed through the debris removal air flow channel, thereby reducing the interference of impurities on the ginning process and ensuring the ginning quality.
[0012] Option five is a preferred option of the basic option, in which a cotton scraping roller is rotatably connected in the machine body, and the cotton scraping roller is located on one side of the main serrated drum.

If the advance angle is greater than 11°, the impact force on the cotton fibers during the ginning process is too large, which may easily cause fiber breakage and reduce the quality of the cotton fibers. If the advance angle is less than 5°, the separation effect of the cotton fibers will be unsatisfactory, and slippage will produce ropes, thereby poor cotton ginning effect.
[0014] Option seven, which is the preferred option of the basic option, the angle between the central axis of the main serrated roller and the line connecting the centers of the main serrated roller and the auxiliary serrated roller is 11°-20°; the angle between the central axis of the main serrated roller and the line connecting the centers of the main serrated roller and the auxiliary serrated roller is set to 11°-20°, which is convenient for improving the flow state of cotton when the main serrated roller is working, and further improving the cotton ginning output. If the angle is too large or too small, it will affect the output and quality. BRIEF DESCRIPTION OF THE DRAWINGS
