Abstract

The invention relates to equipment on product line for one-time health aids of napkin, that is chopping stretching and shift equipment for elastic waistline. The invention is realized by modifying existing equipment, and characterized in that: 1. setting Octoid gear of stretch mechanism on the stand through side plate, position sleeve and fixed base, realizing that Octoid gear rolls round horizontal and vertical shaft, and can move along horizontal shaft;2. setting transfer snifting valve on the two ends of transfer roller, suction distributes symmetrical and uniform, which overcomes phenomenon of less elasticity, deletion and breaking angle; 3. setting rubber layer on outer surface of transfer roller, which makes the adhesion of elastic waistline and material of garment to firm up, and antiseize protection layer of Octoid gear can not be destroyed. The equipment from this invention can run stably with speed of product line more than 200m / min, fast in adhere, waste rate reduced, improves production efficiency; and simple in structure, convenient to adjust.

Description

technical field [0001] The invention relates to equipment on the production line of diapers for disposable hygienic products, that is, an elastic waist cut-off stretch transfer device. Background technique [0002] The elastic waist cutting and stretching transfer device is one of the equipment on the diaper production line. Its main function is to cut the elastic waist and stretch it horizontally, and then transfer and paste it on the fabric of the diaper. It requires sufficient elasticity and firm adhesion. Missing, no chamfered corners, basically symmetrical positions. Since a diaper production line needs to produce diapers of various specifications, and customers have different stretching requirements, the stretching distance of the elastic waist should be adjustable at any time. The known elastic waist cutting and stretching mechanism is inconvenient to adjust, and the suction is too small, resulting in insufficient elasticity of the waist of the diaper product, missin...
