Wide-width cotton core secondary disintegration uniform spreader and uniform spread method

Abstract

The invention relates to a wide-width cotton core secondary decomposition uniform distribution laying machine and a uniform distribution laying method which can effectively decompose wood pulp and cotton pulp which are smashed by a pulverizer and huddled due to static electricity, and also can uniformly distribute and lay decomposed cotton pulp, wherein the wide-width cotton core secondary decomposition uniform distribution laying machine is formed by the opposites surfaces of two tooth rollers, the two ends of roll shafts of the two tooth rollers are mounted on wall plates at two sides of a rack through a support assembly respectively, and certain ends of the two tooth rollers are driven by a motor to synchronously rotate through a pulley drive mechanism. The wide-width cotton core secondary decomposition uniform distribution laying machine and the uniform distribution laying method have the advantages that 1, through the different arrangement of roller pins or tooth disks, the manufacture of 3D (dimensional) cotton cores is realized through control; 2, through the design of a caking physical decomposition structure, the wide-width uniform laying is realized and the manufacturing demands of the cotton cores of different weights and different thicknesses are met; 3, through the device, powder or liquid with fragrance or a medicinal function can be uniformly applied into wood pulp cellulose to increase the soft-power of the cotton cores.

Description

technical field [0001] The invention relates to a wide-width cotton core that can effectively decompose wood pulp and cotton pulp that have been electrostatically clumped after pulverized by a pulverizer, and can spread the decomposed cotton pulp uniformly for a second time. Cloth laying machine and uniform laying method are especially suitable for thin cotton core and large-format products with a width of more than 500mm, such as mattresses and various ultra-thin sanitary products. It belongs to the field of cotton pulp secondary physical decomposition equipment manufacturing. Background technique [0002] CN1624238A, the name "wood pulp pulverizer", includes a frame, a motor, a conveying mechanism, a material guide mechanism and a pulverizing mechanism. The multi-edged jaw plate 3 is characterized in that: the number of teeth on the toothed roller 2 is 20, and each tooth is staggered clockwise by 6 degrees; the diameter of the tooth is 310 mm, and the thickness of the toot...

Problems solved by technology

Its shortcomings: First, after the wood pulp passes through the high-speed crushing roller, due to the effect of static electricity, the crushed fibers will agglomerate, which is suitable for absorbent napkins, baby diapers, and incontinence pants with narrow width and thick thickness. Generally speaking, it can still be used, but for the disposable mattress with wide width and thin thickness, it cannot meet the requirements of fast laying on-line (production line), so two crushing equipment can only be used to complete the processing of the disposable mattress made. The paving of the pad cotton core, and the uneven cotton core layer after paving and forming, not only affects the water absorption performance of the product, but also is extremely uncomfortable to use, and the appearance quality is poor; The lumps are easy to form a bridge at the discharge port of the pulverizer, causing the wood pulp and cotton pulp to not come down, so that the online manufacturing mattress equipment cannot get cotton pulp, resulting in a sharp increase in the scrap rate of online products; the third is due to the use of two The pulverizer jointly completes the laying of the made mattress cotton pulp, so the cost is high, the space is large, and the maintenance cost is high
