Movable cover board carding device for cotton carding machine

Abstract

The invention relates to a movable cover board carding device for a cotton carding machine, which comprises a cylinder, a guide rail, a movable cover board, a driving wheel, a driven wheel, a tensioner and a transition wheel. The guide rail is fixedly arranged on a surface plate of the cylinder; the movable cover board comprises a cover board skeleton, cover board hinge pins, fixing blocks and bearing rolling sleeves; the cover board hinge pins are fixedly connected to both ends of the bottom of the cover board skeleton; the cover board hinge pins are sleeved with the fixing blocks; hinge pin holes on the fixing blocks are provided with limiting grooves; the positions of the two limiting grooves are staggered along the axial directions of the hinge pins; the cover board hinge pins in the limiting grooves are sleeved with the bearing rolling sleeves; the bearing rolling sleeves are in rolling contact with the guide rail; the driving wheel and the driven wheel are arranged in round backs at both ends of the movable cover board; and the tensioner and the transition wheel are arranged at the horizontal end of the movable cover board. Due to adoption of the structure, the distance between the movable cover board and the cylinder is stable; the movable cover board carding device is reliable to operate; maintenance cost is reduced; labor intensity is reduced; the device has superior stability in the actual operating process; a small number of neps and cotton impurities in generated cotton slivers are generated; and the cotton slivers have high fiber quality.

Description

Technical field: [0001] The invention belongs to the technical field of cotton spinning machinery for carding cotton fibers, in particular to a carding device on a carding machine for straightening out cotton fibers and further drawing. Background technique: [0002] The carding machine is used to process cotton fibers and chemical fibers. It belongs to textile machinery. According to the spinning process, carding is an important process. The front process of the carding machine is the combined opening and cleaning machine, and the subsequent process is drawing. machine (carded process) or coiler (combed process). [0003] The working principle of the carding machine is to further open, card and remove impurities from the cotton material sent by the previous process, so that all the coiled cotton loops become basically straight single fibers, and at the same time remove the cleaning process. The broken seeds, impurities and short fibers left over from the drawing frame are ...
