A kind of dry preparation system and process of cotton fiber for pulping

Abstract

The invention provides a pulping cotton fiber dry method material preparation system and process; the process comprises the following steps: firstly using a blowing system to open and willow a cotton bale; then using cotton fiber vertical sorting equipment to vertically sort the opened cotton so as to discharge cotton silvers; using a stock-cutter to cut the cotton silvers so as to evenly cut the cotton fibers in a dry method, thus obtaining dry cut cotton fibers. The pulping cotton fiber dry method material preparation process can evenly cut pulping cotton fiber in the dry method, the cut material length can be flexibly adjusted, and the cut material is good in evenness; in addition, the dry cut cotton fiber can serve as raw material for pulping, thus improving slurry bleaching performance and evenness, reducing production consumption, improving yield, improving slurry quality, reducing pulping cost, and further improving cotton pulp paper making quality.

Description

technical field [0001] The invention relates to a dry preparation system and process of cotton fibers for pulping, and belongs to the technical field of papermaking of cotton fiber raw materials, more specifically, the technical field of material preparation in the papermaking process of cotton fiber raw materials. Background technique [0002] At present, cotton fibers for pulping are generally only treated with impurity removal and dispersion. Although there are production processes for cutting cotton fibers on the basis of impurity removal and dispersion in foreign countries, this process does not carry out longitudinal finishing of cotton fibers, so it is not Cuts cotton fibers evenly. [0003] Longitudinal finishing of cotton fibers refers to the use of carding machines to card the cotton fibers after cleaning and dispersing, so as to arrange the cotton fibers into slivers in the longitudinal direction. The problem is that the current mature carding equipment has a pro...

Problems solved by technology

[0002] At present, cotton fibers for pulping are generally only treated with impurity removal and dispersion. Although there are production processes for cutting cotton fibers on the basis of impurity removal and dispersion in foreign countries, this process does not carry out longitudinal finishing of cotton fibers, so it is not Cut cotton fibers evenly

[0003] Longitudinal finishing of cotton fibers refers to the use of carding machines to card the cotton fibers after cleaning and dispersing, so as to arrange the cotton fibers into slivers in the longitudinal direction. The problem is that the current mature carding equipment has a production capacity of 50-100 kg / hour

[0004] The cutting technology and equipment used for cotton fiber cutting are all formed products. At present, the technology and equipment can complete the cotton fiber cutting operation, but the technical indicators of the finished product after cutting are very low. The cutting length is generally about a few centimeters, and the feeding speed is low. , the number of cutter blades is small, so the equipment capacity is low
