Ingot-suspended automatic spinning machine

Abstract

Forty thousand viscose filament yarn spinning workers exist in China at present, but have to change jobs every 3-5 years as suffering from carbon bisulfide gas; and since the acid bath for the wet spinning technique of viscose filament yarn uses 240 g / l sulfuric acid which is seriously corrosive, a common spinning mechanism can not be easily available, and the spinning can only be carried out manually, which is a problem in the world. A full continuous spinning machine has appeared abroad; however, by using the full continuous spinning machine, the after-treatment technique of the spinning cake must be moved onto the spinning machine for monofilament treatment, and thus, the full continuous spinning machine has the defects of huge equipment, high power consumption and poor quality of rayon filament, and is hard to popularize. The ingot-suspended automatic spinning machine disclosed by the invention uses an energy-saving centrifugal cylinder CN200710071331,4 as the main body, can operate instead of human labor, and thus, relieves the workers of the damage from carbon bisulfide gas, thereby lowering the labor and production cost. By the aid of Patent ZL88104569 technology, the invention can increase the spinning speed by 20% as compared with the prior art, and can also save powder of electric ingot consumption by 30% on the basis of the energy-saving centrifugal cylinder. The spinning cake can be directly released from the factory, thereby widening the application range and benefiting the social production.

Description

Technical field: [0001] The invention relates to a suspension-type automatic doffing machine for viscose filament centrifugal spinning machines, which can transform all centrifugal spinning machines, and can also design and manufacture new suspension-type automatic doffing spinning machines. technical background: [0002] Viscose filament is a wet-spinning process, and doffing must be done manually. Carbon disulfide gas in the spinning workshop is unavoidable for workers, and workers must be replaced every 3 to 5 years. / l Corrosion is serious, and it has become a worldwide problem that the general doffing mechanism cannot enter. Foreign countries have introduced full continuous spinning machines, but they are also difficult to popularize because of large equipment, high power consumption, and poor quality. In addition, due to the limitations of workers doffing, the spinning speed R531 91m / min, R53580m / mm can not be increased. Invention content: [0003] A suspension-ty...
