Description

Technical Field

[0001] The patent of this invention relates to the field of textile processing technology, specifically, to a hybrid yarn traceless drawing mechanism and method based on an air-jet spinning system. Background Art

[0002] Drawing mainly includes combining, drafting, mixing and slivering. Combining is to combine 6-8 cotton strips and feed them into the drawing frame to make a cotton strip. Since the thick and thin sections of each cotton strip have a chance to overlap with each other, the unevenness of the long segments of the strips is improved. Drawing is to lengthen and thin the strips to their original extent, and at the same time improve the state of the fibers through drafting, so that the hooks and curled fibers can be further straightened and paralleled, and the small cotton bundles can be further separated into single fibers. By changing the drafting multiple, the quantitative control of the drawn strips is effective to ensure that the weight deviation and weight unevenness of the spun yarn meet the national standards. The drawing frame is an important equipment in the air-jet spinning process. Its function is to improve the internal structure of the cotton strips, thereby improving their long segment uniformity and reducing the weight unevenness, so that the fibers in the strips are straightened and parallel, reducing hooks, and making the fineness meet the requirements, so that raw materials of different types or qualities are mixed evenly to achieve the specified mixing ratio.

Its beneficial effects are recorded in the following: the dust and cotton wool raised during the drawing process are sucked away by a dust suction hood to avoid affecting the surrounding environment; the cotton slivers pass between the upper cleaning roller and the lower cleaning roller, and the brush layer contacts the cotton slivers, thereby brushing off the long cotton lint on the surface of the cotton slivers; under the elastic force provided by the buffer spring, the roller body can maintain contact with the cotton sliver, improving the cleaning effect; when cleaning the cleaning roller, the cleaning roller is driven to rotate by the belt drive of the external motor, and at the same time, the cylinder extends, so that the brush block contacts the roller body, and the impurities adhering to the roller body are brushed off by the brush block and sucked away by the dust suction hood. The motor drives the screw to rotate, causing the brush block to move horizontally, and the cleaning roller is fully cleaned. However, it has the following problems.

[0004] Its through to the lint on the surface of the sliver and so on impurities is cleaned, thereby auxiliary sliver carries out and the sliver operation, to promote the sliver and the sliver effect is limited, the existing technology, the roller of the sliver machine in the long-term work, because the bearing of installing the roller is damaged and no oil and so on condition, lead to the roller appears the condition of jumping, thereby produces the mechanical wave, further influence the effect of drawing the sliver, further influence the effect of sliver and the sliver, the existing technology prevents the bearing of installing the roller from being damaged and no oil and so on condition produces the mechanical wave mode usually for; Regularly check the lubrication state of the roller, regularly oil, clean the shaft sleeve, etc., eliminate the drawing mechanical wave due to the operation of the shaft sleeve and the rubber roller, but in actual textile work, usually after the quality problem of sliver appears, can find the generation of mechanical wave, usually after knowing, cannot automatically alarm when the roller appears jumping due to the damage of the bearing of installing the roller, thereby cannot stop the sliver operation when the mechanical wave appears, easy to cause greater loss, there is certain deficiency, in order to solve the above problems, the mixed yarn traceless drawing mechanism and method based on air flow spinning system are provided.
