Forming device and forming method of ultra-thin cotton core for disposable sanitary products

Abstract

The invention belongs to the technical field of equipment of production lines for disposable hygiene products, and particularly relates to a forming device and method for ultrathin cotton cores of disposable hygiene products. The forming device comprises a pulverizer, an output end, a flock collection cabin and a forming hub. The flock collection cabin is provided with an upper opening connected with an outlet of the pulverizer and a circular arc lower opening covering the peripheral surface of the forming hub. The forming hub comprises a rotary disc, a suction ring, a negative pressure cabin and a die shoe. The die shoe is provided with a die shoe cavity and placed on the surface of the suction ring. The suction ring is installed on the rotary disc. The rotary disc drives the suction ring to rotate when rotating, and the die shoe rotates relative to the negative pressure cabin and the flock collection cabin. A puncture traction mechanism is arranged on one side of the flock collection cabin. The invention further provides the method for manufacturing the ultrathin cotton cores of disposable hygiene products by the utilization of the forming device. By means of the forming device and method, production efficiency is improved, the forming device is simple in structure and flexible in combination, and produced cotton cores are ultrathin, attractive and compact in texture.

Description

technical field [0001] The invention belongs to the technical field of production line equipment for disposable sanitary products, and in particular relates to a forming device and a forming method for ultra-thin cotton cores of disposable sanitary products. Background technique [0002] Disposable sanitary products are also called absorbent disposable products, the English name is "absorbent disposable products" or "hygiene products", including women's sanitary napkins, sanitary pads, tampons, baby diapers, adult diapers and other adult incontinence products, Pet mats, etc. The global sales of disposable sanitary products are about more than 40 billion US dollars. The raw materials of disposable sanitary products mainly include non-woven fabrics, super absorbent resin (SAP) and fluff pulp. Due to the rising price of oil and pulp in the international market, the prices of various raw materials for disposable sanitary products have continued to rise in recent years. Among th...

Problems solved by technology

When the ultra-thin cotton core size is large, there are many difficulties in manufacturing

First of all, there are difficulties in forming. The one-sided suction of the traditional hub negative pressure warehouse will cause the inner and outer thickness of the cotton core to be uneven; It is easy to cause breakage when the surface is on the surface, and the absorbency is reduced; the transferred cotton core is easy to fly before it is separated from the surface material
