Problems solved by technology

[0009] This technology solves the problem that SAP and fluff pulp cannot be fully mixed, and at the same time fundamentally solves the problem of SAP spilling during the transfer of absorbent cores such as sanitary napkins, incontinence pads, and diapers between the mold wheel and the transfer wheel

Embodiment Construction

[0042] The defibrillator (6) defibrates the fluff pulp fiber board into fluff pulp fibers (21), and the wind generated when the defibrillator rotates drives the fluff pulp fibers into the die wheel cover (1); The introduction can effectively play the suspending and promoting effect of compressed air flow on the transportation of SAP (22); the content of SAP in compressed air is less than 5kg / m3; SAP is transported under positive pressure when it passes through the polymer water-absorbing material adding mechanism, The working pressure of the compressed air is 0.3-0.8 MPa, and the preferred working pressure of the compressed air is 0.4-0.6 MPa.

[0043] The SAP enters the SAP adding mechanism (7) through the SAP measuring mechanism (5), the flow rate of the SAP in the SAP adding mechanism should be within 20-35m / s, and the high-speed compressed air (20) is charged into the SAP adding mechanism and flows to the SAP On the other side of the adding mechanism, rotate the material o...

Abstract

The invention relates to a device and a method thereof for manufacturing a die wheel laminar flow mixed absorption core. Through additionally arranging laminar flow equipment, the technological structure of a manufactured absorption core and die wheel equipment are changed. Meanwhile, the moving direction and the moving speed of an SAP in a die wheel cover can be controlled. In this way, the SAP and the fluff pulp are mixed uniformly. On the condition that the SAP and the fluff pulp are mixed orderly, the mixing ratio of the SAP in the absorption core is increased. Since the mixing ratio of the SAP in the absorption core is increased, the absorption core is lighter and thinner. Meanwhile, the liquid absorption capacity of disposable hygiene products is increased. The technological structure of the absorption core is changed, wherein the absorption core is provided with multiple layers instead of only one layer. The SAP of different ratios and different performances can be added inside each layer of the absorption core. Therefore, each layer of the absorption core is unique in liquid absorption capacity respectively, so that the rapid liquid absorption function of the absorption core is realized.

Description

technical field [0001] The invention belongs to the field of personal hygiene, and relates to disposable hygiene products such as sanitary napkins, incontinence pads, diapers, etc., and specifically relates to the use of a die wheel layer for absorbent cores of disposable hygiene products such as sanitary napkins, incontinence pads, diapers, etc. The equipment and method for flow preparation can achieve ultra-thin characteristics of the absorbent core of disposable sanitary products, and at the same time have the performance of layered absorption and rapid liquid absorption. Background technique [0002] The existing disposable absorbent products on the market, such as the absorbent cores of sanitary napkins, incontinence pads, diapers, etc., are made of fluff pulp with SAP (Super Absorbent Resin) and pressed. SAP and fluff pulp are added into the cover at the same time, in which SAP enters the die wheel cover by free fall; fluff pulp is driven into the mold wheel cover by t...
