Absorber manufacturing device

Abstract

The invention discloses an absorber forming device which comprises an adsorption guide unit, a plurality of forming units, a rotating driver and a fiber conveying unit, an air draft channel and a main flow guide air channel are formed in the adsorption guide unit, the rotating driver is in transmission connection with the forming units, and the fiber conveying unit is provided with an input port and an output port. A plurality of grooves which are distributed in the circumferential direction are formed in the periphery of the forming unit, the long axis direction of each groove is perpendicular to the circumferential direction, and a screen structure is arranged at the bottom of each groove so as to form a forming area of the absorber. And under the driving of the rotary driver, each forming area periodically rotates through the first fiber accumulation area along with the forming unit. The screen structure of the forming area comprises a central area and an edge area, and the aperture ratio of the central area is smaller than that of the edge area, so that the negative pressure of the main flow guide air channel can ensure the plumpness of paper pulp fibers and macromolecule water-absorbent resin at the two ends of the absorber, and the forming effect of the absorber in the transverse direction is improved.

Description

technical field [0001] The application relates to the technical field of disposable sanitary products manufacturing equipment, especially to the fields of mini towels, panty liners, etc., and specifically to an absorber manufacturing device. Background technique [0002] Existing absorbent sanitary products, such as small sanitary napkins (also known as mini napkins) and panty liners, etc. for women's physiology, the absorber part is mainly composed of fluff pulp fibers and polymer water-absorbent resin. Therefore, it is necessary to install an absorbent body manufacturing device in the manufacturing equipment of sanitary napkins / panty liners. This kind of absorbent body manufacturing device usually grinds the pulp raw material sheet through a pulverizer to form fluff pulp fibers, which can also be called pulp fibers, and then The pulp fiber is fed into the fiber conveying unit connected with negative pressure, and the pulp fiber is mixed with polymer water-absorbing resin i...
