Absorption core production technology

Abstract

The invention relates to an absorption core production technology which is high in production efficiency and low in production cost, and structures of produced absorption cores are simplified. The absorption core production technology includes the following steps that first, raw materials are conveyed into a pulverizer to be pulverized and then conveyed out; second, pile pulp is conveyed into a mold cavity and mold wheel device, high polymer material is added into the pile pulp, and forming is performed; third, formed cotton cores are adsorbed through a transfer and adsorption device and transferred onto a conveying belt to be conveyed; fourth, in the conveying process, the upper portion of the cotton cores are covered with a layer of non-woven cloth, the bottoms of the cotton cores are covered with a layer of PE film, and the cotton cores are made to adhere to the non-woven cloth and the PE film in an adhesive spraying mode; fifth, the cotton cores are conveyed into a smoothing and pressing device to be pressed and smoothed, and then the cotton cores are conveyed out; sixth, the edges of the cotton cores are coved, and then the cotton cores are longitudinally folded; seventh, the cotton cores are conveyed into a cutting device, and tailoring and edge removing are carried out to obtain finished products; eighth, the cotton cores are folded three times, and the folded cotton cores are compacted through a pressure device and then conveyed out.

Description

technical field [0001] The invention relates to the field of disposable absorbent articles, in particular to a production process of an absorbent core. Background technique [0002] In the field of existing disposable absorbent products, such as diapers, sanitary napkins, etc., the absorbent core is usually composed of a cotton core sandwiched by upper and lower layers of toilet paper. The cotton core here is usually output by the mold wheel. , and its output is also continuous, and the main function of the toilet paper is to clamp the continuous long cotton core to increase the firmness and stability of the cotton core and prevent the cotton core from loosening during transportation. In actual use, toilet paper has no actual function. Because the cotton core required by the product is often in small pieces, this long strip of cotton core needs to be cut by a cutting device in subsequent production, and then input into the finished product forming process by means of diffe...

AI Technical Summary

Problems solved by technology

The way of using toilet paper clamping in the existing technological process is a well-known technology in the industry, and it has been used for many years. Although the practicability of the absorbent core produced by this method is good, the technological process for producing this absorbent core Longer, more production equipment and more operators, which undoubtedly greatly increases the production cost, and because there are more machines, it is easy to lead to more frequent failure rates, which is not conducive to the progress of production activities
