Fiber-combing metal cardcolthing

Abstract

The invention discloses a fiber tidying metal card clothing for spinning tidying machine. This machine is composed by the clothing base and the saw tooth in the base. The saw tooth of different thickness and base form tooth level surface, and said surface is one wave which is set slanting, also can extend along the direction of the length of the clothing. This metal clothing has a good effect forremoving debris and a high efficiency for transferring fiber. It's convenient to use and has a simple structure.

Description

technical field [0001] The invention relates to a carding element for a spinning machine, in particular to a metallic card clothing for fiber carding. Background technique [0002] Metal card clothing is an important carding element widely used in spinning machines such as carding machines and combing machines. The surface of the roller or carding plate of carding elements such as combs plays the role of grasping, opening, removing impurities, transferring and agglomerating the fibers to be carded. [0003] At present, the basic structure of metal card clothing is to set the card clothing serrations on the base of the card clothing. The thickness of the card clothing serrations is generally smaller than the thickness of the card clothing base. The root step surface is a long and narrow inclined plane or horizontal plane, and extends along the length direction of the card clothing. At the same time, because there is a thickness difference between the thickness of the sawtoo...

Problems solved by technology

[0004] Since the root step surface of the sawtooth root is a plane, the airflow formed by the relatively high-speed movement of the metal card clothing always follows the plane when the metal card clothing is carding fibers, and the covered metal card clothing is tangential along the surface. Therefore, the dust removal of fibers and the transfer of fibers between needle faces can only rely on the centrifugal force formed by the rotation of the rotating body, while it is more difficult to transfer the carding medium between the tooth gaps of fixed carding elements

On the one hand, when the sawtooth of the card clothing is scratched, especially when the sawtooth of the card clothing becomes rough, it is easier to get scratched on the sawtooth, and dust and short fibers will also fill the tooth gap, which will directly affect the effect of carding and descaling; On the other hand, due to the extremely light weight of the fiber and the effect of air resistance, the carded fiber is prone to poor transfer, especially when the carding element is fixed, the speed of the carding roller body is low or reduced, and the tooth gap is filled with the carding medium. , the fiber transfer ability is greatly reduced, and the fiber cannot be repeatedly transferred between the needle faces, which directly affects the carding effect and product quality
