Oscillating opening fiber carding method

Abstract

The invention discloses an oscillating opening fiber carding method. The oscillating opening fiber carding method comprises the following steps: a, a fiber layer unwound from a fiber roll is fed to alicker roller by a feeding roller to perform opening, and the long fibers in the fiber layer are fully opened and loosened under the oscillating opening action of opening needle teeth; b, the fiber layer is striped by a cylinder after the fiber layer is opened by the licker roller, and the fiber is subjected to oscillating opening further; c, the stripped fiber layer enters a cylinder-cover platecarding area with the cylinder, and are carded into singe fibers; d, the carded fiber layer goes out of the cylinder-cover plate carding area, and enters a cylinder-doffer carding area, and oscillating carding is performed on the fibers between cylinder blunt scaly needle teeth and doffer carding needle teeth; e, the condensed fiber layer is stripped by a stripper roller to form a fiber net, the fiber net is gathered by a bell mouth and is squeezed by a big pressing roller to form slivers. The oscillating opening fiber carding method is suitable for caring when the fiber material has a low thread density or when the fiber strength is low, can prevent the fibers from being stuffed, and can improve the carding effect of low damage and the strong release of the soft and weak fibers.

Description

technical field [0001] The invention relates to the field of cotton carding in textile machinery, in particular to an oscillation type carding method for opening fibers. Background technique [0002] In the spinning process, all kinds of fibers need to be carded before the yarn is spun. The carding system is through the tangential movement between various card clothings in the carding machine, through the cylinder card clothing, licker-in roller The card clothing and doffer card clothing cooperate with each other to realize the carding of fibers. However, when the linear density of the fiber raw material is low or the fiber strength is low, it uses an ordinary carding machine for operation, usually the needle teeth cannot release the fiber quickly after the fiber is grabbed, and the disadvantages of fiber clogging the needle teeth are prone to occur. The fiber cannot be combed more fully, resulting in large fiber damage, many defects in the output fiber web, holes are prone...
