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 defibrating machine (6) defibrates the fluff pulp fiberboard into fluff pulp fibers (21), and the wind force generated when the defibrating machine rotates drives the fluff pulp fibers into the mold wheel cover (1); The introduction can effectively exert the suspending and driving effect of the compressed air flow on the SAP (22) transportation; the content of SAP in the compressed air is less than 5kg / m3; when the SAP passes through the polymer water-absorbing material adding mechanism, it is positive pressure conveying, 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] SAP enters the SAP adding mechanism (7) through the SAP metering mechanism (5), the flow velocity of SAP in the SAP adding mechanism should be within 20-35m / s, and the high-speed compressed air (20) is filled into the side of the SAP adding mechanism and flows to the SAP On the other side of the adding mechani...

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 a disposable hygienic product such as a sanitary napkin, an incontinence pad, a diaper, etc., and specifically relates to a mold wheel layer used in the absorbent core of a sanitary napkin, an incontinence pad, a diaper, and the like. The equipment and method for flow preparation achieve the ultra-thin characteristics of the absorbent core of the disposable sanitary product, and simultaneously have the performance of layered absorption and rapid liquid absorption. Background technique [0002] The existing disposable absorbent products on the market, such as sanitary napkins, incontinence pads, diapers, etc., are made of fluff pulp and SAP (super absorbent resin) after pressing. The traditional absorbent core manufacturing process is in the mold wheel. Add SAP and fluff pulp into the cover at the same time, among which SAP enters the mold wheel cover in the way of free fall; the flu...
