Description

a carding machine

technical field

The present application relates to the field of textile machinery, in particular to a carding machine.

Background technique

Carding machine is a textile machine used to process cotton fiber and chemical fiber. 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 the drawing frame (carding process) or sliver coiler (combing process).

The working principle of the carding machine is to loosen, remove impurities, and comb the cotton delivered after cleaning and mixing into single cotton, and make uniform raw sliver that meets certain requirements for the next spinning process. The carding machine is mainly composed of licker-in rollers, cylinders, movable cover plates, fixed cover plates and doffers. The licker-in rollers are often equipped with impurity removal components. During work, the cotton is loosened by the licker-in rollers and then transferred to the cylinder. The carding area between the forest and the movable cover and the fixed cover is separated to obtain loose cotton, and the loose cotton is transferred to the surface of the doffer to form a cotton layer, which is accumulated into a sliver after peeling off.

In view of the related technologies mentioned above, the licker-in roller is used as the first step of the carding machine to simply card and remove impurities from the cotton. There are still many impurities, cotton linters, neps, etc. that have not been cleaned up, and the cotton is transported to the cylinder. When combing is continued at the position, the separated impurities, cotton linters, neps and other substances cannot be discharged in time, but are repeatedly combed and refined, and these refined impurities are finally mixed into the cotton web to form a semi- Finished sliver, resulting in a decline in the quality of semi-finished sliver; for some larger manufacturers, they will continue to update their equipment, add dust removal components at various positions on the carding machine, and control dust removal through the PLC intelligent system, but for some smaller manufacturers Manufacturers, on the one hand, invest huge costs in new equipment, on the other hand, the maintenance of the intelligent control system requires professionals to operate, the process is cumbersome, costly, and time-consuming.
