Three-dimensional punching equipment for disposable hygienic material and punching method thereof

Abstract

The invention relates to three-dimensional punching equipment for a disposable hygienic material and a punching method thereof. An air-draft shaping roll, a concave punching roll and a pull roll are arranged on the horizontal straight line; a convex punching roll and the concave punching roll are matched, and the convex punching roll is arranged on the concave punching roll; electrical heated tubes are respectively arranged in the convex punching roll, the concave punching roll and the pull roll and are electrified by a conductive slip ring on the end part of the electrical heated tube; a plate-type thermocouple is respectively positioned in the concave punching roll, the concave punching roll and the pull roll and is electrified by a conductive ring; and the electrical heated tube is controlled by a PLC (programmable logic controller) to work. The three-dimensional punching equipment has the advantages that a flat nonwoven raw material is pressed into a three-dimensional trepanning product with double faces; the thickness of the nonwoven raw material is increased to 20-30 times after the nonwoven raw material is punched and stretched; the surface of a hygienic product carries outpunctuate contact with the skin of a human body; a shaped three-dimensional trepanning liquid storage tank can store a great quantity of menstruation liquid and urea liquid without lateral leakage, so that the skin of the human body still keeps dry and comfortable; and the comfort degree of the product is greatly improved.

Description

technical field [0001] The invention relates to a three-dimensional perforated surface capable of forming a three-dimensional structure on both sides of non-woven fabric perforation, so as to achieve large liquid storage, side leakage prevention, and point contact three-dimensional three-dimensional perforation equipment and perforation for disposable sanitary materials The method belongs to the field of manufacturing non-woven fabric punching equipment. Background technique [0002] CN101688344A, name "non-woven fabric punching equipment and method, and non-woven fabric manufactured by the same", the equipment and method are economical and cost-effective. The invention also discloses the non-woven fabric manufactured by using the equipment and method. The non-woven fabric punching device includes a first roller having a plurality of needles on the outer peripheral surface, and two or more second rollers rotating relative to the outer peripheral surface of the first roller,...

AI Technical Summary

Problems solved by technology

[0004] The common disadvantages of the above-mentioned background technologies: one is that it is impossible to form three-dimensional three-dimensional hole grooves on both sides of the non-woven fabric, so the perforated non-woven fabric not only has a small liquid storage capacity, but also cannot solve the problem of side leakage, thus The surface of the perforated non-woven fabric cannot form a dry surface, which makes people's skin feel very uncomfortable;

[0005] Influenced by the size of the material, continuous drilling operations cannot be formed, and the material needs to be changed separately
