Cotton core forming process

Abstract

The invention relates to the field of manufacturing of sanitation supplies and provides a cotton core forming process. The process comprises the following steps: (1) applying a composite polymer layer to the lower surface of an intermediate fluffy non-woven fabric layer and feeding the composite polymer layer to a material transfer composite roller; (2) conveying a bottom fluffy non-woven fabric, performing edge correction, spraying glue, and feeding to the material transfer composite roller; (3) gluing the composite intermediate fluffy non-woven fabric layer and the upper surface of the intermediate fluffy non-woven fabric of the composite bottom fluffy non-woven fabric layer, and feeding to a second firm pressing mechanism; (4) performing massive discontinuous glue spraying on the upper fluffy non-woven fabric, discontinuously arranging the polymer layer and fixedly laminating with the intermediate fluffy non-woven fabric and the bottom fluffy non-woven fabric, and completing compounding of the three layers; and (5) folding, covering, compacting and reinforcing excessive parts of the bottom fluffy non-woven fabric compared with two sides of the intermediate fluffy non-woven fabric and the upper non-woven fabric, thereby obtaining the formed cotton core. According to the process disclosed by the invention, the problems that the conventional cotton core is high in forming cost, complicated in process and long in production line are solved.

Description

technical field [0001] The invention relates to the technical field of hygiene product manufacturing, in particular to a cotton core forming process. 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 made of a mold wheel. output, and its output is also continuous, and the main function of toilet paper is to clamp this continuous long strip cotton core to increase the firmness and stability of the cotton core and prevent the cotton core from loosening during transportation, while 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 ...

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
