Problems solved by technology

Compared with the composite process of finished elastic materials, the online production of elastic composite materials using non-woven fabrics and elastic bands can effectively reduce production costs, but there are technical difficulties in the production of online longitudinally stretched elastic materials. There is a speed difference between the single longitudinal elastic material cut out by the stretched elastic material and the surface layer to be compounded, so it cannot be directly compounded; the single longitudinal elastic material needs to be maintained in a stretched state and turned transversely to be compounded with the product

Abstract

The invention discloses an on-line waistline cutting and rotating pitch-variable assembly for a disposable sanitary product. The assembly comprises a cutting mechanism, a reversing mechanism and a speed change mechanism, wherein the three mechanisms are respectively and fixedly arranged on an assembly rack, the cutting mechanism comprises a bearing seat and a cutter roller which are fixedly arranged on the assembly rack, the two ends of the bearing seat are provided with a cutter head and a rotating disc respectively, at least two cutter anvils are arranged at the outer circumferential surface of the cutter head and are meshed with a cutter of the cutter roller, and a sucking disc is arranged between every two cutter anvils. Therefore, the device occupies a small main machine space, is powerful in function and compact in structure, and manufacturing and compositing of an elastic waistline are synchronously realized in a main machine by the adoption of spandex silks and non-woven fabrics.

Description

technical field [0001] The invention relates to the field of manufacturing equipment for disposable sanitary products, in particular to an on-line waistline cutting rotary variable pitch assembly for disposable sanitary products. Background technique [0002] Elastic materials are widely used in the waist elastic ring of diapers to increase the fit and comfort of diapers when worn. It can be said that they are an indispensable component of diaper products. Manufacturers who produce diapers need to purchase special composite elastic fiber non-woven fabrics as elastic waist or elastic ears. The finished elastic material is expensive, and the elastic stretch direction of the rolled elastic material is parallel to the axis of the reel. The traditional elastic material application method is , the cutting assembly cuts out a single elastic material horizontally, and the single elastic material is transferred to the peeling wheel through the transfer roller, and the peeling wheel s...
