A carding device for automatically adjusting carding density

Abstract

The invention discloses a carding device for automatically adjusting the carding density in the technical field of carding machine pre-thinning, comprising a density-adjusting carding assembly, the density-adjusting carding assembly includes a shell and a cotton path separated inside the shell, the cotton The road includes a vertical cotton road 1, a cotton groove with a "V" shape in cross section, a vertical cotton road 2, an inclined cotton road 3 and a "ㄱ" shaped cotton road 4. The cotton feeding assembly is installed on the right groove cavity of the cotton groove, the transfer assembly is installed on the groove cavity of the fourth cotton path, and the cotton feeding roller is installed at the right port of the cotton path three, and the cotton feeding roller is installed on the right side of the cotton feeding roller. The licker-in roller is installed to ensure that the feeding roller and the licker-in roller can effectively bite into the cotton block layer, and avoid the large compression of the cotton block in the third cotton path, that is, the density of the cotton block layer passing through the third cotton path will not be higher. Large size ensures that the feeding roller and licker-in roller can effectively loosen and pre-thinn the bitten cotton block layer.

Description

technical field [0001] The invention relates to the technical field of carding machine pre-thinning, in particular to a carding device for automatically adjusting carding density. Background technique [0002] Carding machine, a kind of textile machinery, is used to process cotton fiber and chemical fiber. It is mainly divided into three parts: the pre-thinning part, which is mainly composed of licker-in rollers, cotton feeding rollers, cotton feeding boards, dust removal knives and small drain bottoms. Composition; the main comb part is mainly composed of cylinders, cover plates, doffers and large drain bottoms and other components; the stripping part is mainly composed of stripping rollers, bell mouths, large pressure rollers and sliver coilers and other components. [0003] Among them, the pre-thinning part is mainly to pre-thinn the cotton block layer sent from the cotton opening box. The common problem in the pre-thinning process is that the cotton block layer in the co...

Problems solved by technology

[0008] The purpose of the present invention is to provide a carding device that automatically adjusts the carding density, so as to solve the problem in the above-mentioned background technology that when there are many pieces of cotton sent from the opening box to the cotton road, the pressure of the self-adjusting and equalizing parts and the space of the cotton road can be solved. The cotton block will be compressed, and the density of the cotton block layer will become larger. However, the decomposition force of the cotton block layer by the feeding roller and the licker-in roller is a constant value, and the high-density cotton block layer is fed to the cotton roller and licker-in roller. Biting in is not conducive to the loosening and pre-thinning of the cotton block layer by the cotton feeding roller and the licker-in roller. In addition, when the cotton block layer is too thick, when it is compressed, it will also push up the self-adjusting and leveling parts through the reaction force, so that the feeding Cotton rollers and licker-in problems biting into too thick a cotton block layer
