Problems solved by technology

CN201056597Y discloses a fiber carding metal card clothing, which is characterized in that it adopts card clothing serrations of different thicknesses and a wave-shaped tooth root step surface, which has good trash removal effect and fiber transfer rate, but still has complex structure and difficult processing , Fibers between pin teeth are easy to block, etc.
However, there are also problems such as weak single-toothed teeth that are prone to breakage due to weak strength of the single-tooth body, and easy to damage fibers with multi-toothed points, resulting in more short-lint and neps during the carding process, which greatly reduces the working efficiency of the carding machine and seriously affects carding. product quality

Abstract

The invention relates to a metal card clothing for carding superfine fibers, which comprises a base part, and a plurality of needle teeth are sequentially arranged on the base part; tooth tops of the pin teeth are of an inclined tooth top structure, and inclined tooth top faces are arranged at the tops of the tooth tops. A first working surface is arranged on one side of each pin tooth, and the first working surfaces are in smooth connection with the oblique tooth tip surfaces; second working surfaces, stepped inclined edge tooth surfaces and arc surfaces are sequentially arranged on the other sides of the pin teeth, and the second working surfaces are in smooth transition connection; and the arc surfaces of the needle teeth are in smooth transition connection with the second working surfaces of the adjacent needle teeth, so that a complete carding area is formed, and the carding, impurity removal and transfer processes of the superfine fibers are completed. Compared with the prior art, the device is simple in structure and high in applicability, superfine fibers can be effectively prevented from being deposited and wound around the roller, the card clothing carding work efficiency is effectively improved, manual cleaning is not needed, and the labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of textile machinery and equipment, in particular to a metal card clothing for superfine fiber carding. Background technique [0002] With the rapid development of the textile industry, the processing of ultra-fine fibers has higher and higher carding requirements and carding precision for carding machines. Different from conventional fibers, due to the large specific surface area of ​​ultra-fine fibers, increased friction and strong electrostatic effect, problems such as fiber winding and fiber entanglement are prone to occur during the carding process. However, the structure of the existing carding machine has basically been finalized, and it can only be improved by improving the carding clothing accessories to strengthen the carding effect, reduce fiber damage, and increase fiber transfer. However, the existing carding machine cylinder clothing structure is difficult to meet the ultra-fine Fiber carding....
