Pull net type fiber separator based on sanitary towel cotton yarns and paper pulp membrane sheets

Abstract

The invention discloses a pull net type fiber separator based on sanitary towel cotton yarns and paper pulp membrane sheets. The pull net type fiber separator structurally comprises a gas discharge column cylinder, a yarn pulling output cylinder, a piston cylinder, an axis rotary pump, a pull net separation roller, a sanitary towel guide pipe, an electric control box and a base block. According tothe invention, the pull net separation roller is matched with the sanitary towel guide pipe to form the counter weight centrifugation and centripetal throwing operation of external winding of cottonyarns and internal filling of water-containing paper pulp, and when the arc buckle sliding brush block of the rail frame ring is matched to scrape and brush the membrane sheet, the debris forms the irregular axis of the paper pulp and the periphery of the paper pulp is wrapped and collected, so that the cotton yarn fiber in the middle position is separated from the paper pulp membrane sheet belt,the membrane sheets bonded by the cotton threads fall off to the sealing ring under the action of strong centrifugation and centripetal force and fall back to the middle position along the centripetalair holes, the purity of the fiber separation operation in the sanitary towel is high, the screened materials are high in collection degree and free of residues, the working period is short, and theprecision and the efficiency of batch fiber separation operation are improved.

Description

technical field [0001] The invention relates to a pull-net type fiber separator based on sanitary napkin cotton yarn and pulp film, and belongs to the field of sanitary napkin fiber separation. Background technique [0002] Sanitary napkins are commonly used by women during their monthly menstrual period. Strict screening and inspection operations are carried out for the cotton core pulp water-absorbing membrane of the sanitary napkin and the cotton yarn interwoven block of the peripheral padding, and the sterilization and high-purity separation of fibers are meticulous. Accurate product testing operation improves the safety of sanitary napkins. The shortcomings of the current technology that need to be optimized are: [0003] The pulp membrane of sanitary napkins has a high viscosity, which will cause the pulping and pulling phenomenon on the outer weaving block of the bonded cotton yarn, which will cause the membrane to be torn with the end of the cotton yarn, and the memb...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a net-type fiber separator based on sanitary napkin cotton yarn and pulp film to solve the problem of the high viscosity of the pulp film of sanitary napkins. The weaving block around the thread will cause the phenomenon of patina pulling, which will cause the membrane to be torn between the cotton yarn end, which will reduce the area of ​​the membrane and allow the cotton yarn to be mixed with pulp impurities, which will affect the fiber separation operation of the sanitary napkin in the later stage and increase the difficulty of fiber drawing of the sanitary napkin. , so that the overall quality of sanitary napkins is recycled and interwoven with sub-lines to take model materials, which causes troubles, and also causes impurities on the pulp film surface to remain and fall off in the yarn winding operation of the fiber separator. The dust inside the equipment interferes with the normal operation of the equipment
