Problems solved by technology
This kind of disposable diapers needs to have a wide non-water-permeable outer layer and a water-permeable surface layer, and it is manufactured by removing materials, especially for adult diapers. The raw materials cannot be reused, resulting in low material utilization rate and high product cost. Therefore, it is necessary to improve the existing diaper manufacturing method and propose a new diaper manufacturing method, so as to save materials. Purpose

Embodiment Construction
[0029] This embodiment is a preferred embodiment of the technical solutions proposed by the present invention, which proposes a method for manufacturing disposable diapers, combining with figure 1 and figure 2 shown, including the following steps:
[0030] Step 1. Join the hook-shaped connector on the continuous sheet, specifically:
[0031] Step 1.1, use the cutting device 1001 to cut the continuous hook-shaped sheet along the center line of the continuous hook-shaped sheet to form two hook-shaped sheets, and then proceed to step 1.2;
[0032] Step 1.2, the two hook-shaped sheets obtained by cutting are pulled along the conveying direction by the pulling device 1002, and then proceed to step 1.3;
[0033] Step 1.3, change the conveying direction of the two hook-shaped sheets through the transition guide wheel 1003, and guide the two hook-shaped sheets upward and downward respectively into the deviation correction device 1004, change the conveying position of the two hook-s...

The present invention proposes a method for manufacturing disposable diapers, which includes the following steps: dividing a continuous sheet of non-woven fabric material according to a cutting line to form a continuous first sheet and a second sheet with uneven distribution, and the convexity of the first sheet is The parts and the concave parts are the same size as the convex parts and concave parts of the second sheet; the first sheet and the second sheet are conveyed so that the first sheet and the second sheet are three-dimensional with each other along the width direction crossing the conveying direction cross; adjust the conveying length of the first sheet so that the convex part of the first sheet corresponds to the convex part of the second sheet, and the concave part of the first sheet corresponds to the concave part of the second sheet; The opposite sides of the second sheet are laminated to both sides of the absorbent body, respectively. The invention has the advantages of avoiding the generation of waste materials, reducing the use of materials, and effectively saving the cost. At the same time, the finished product produced by the manufacturing method has good air permeability and is comfortable to wear.
Description
technical field [0001] The invention relates to the field of making diapers, in particular to a method for making disposable diapers. Background technique [0002] Disposable diapers include nursing products and baby diapers designed for patients with urinary incontinence and paralysis, which are easy to use and replace. At present, the commonly used structure of disposable diapers on the market mainly includes a non-water-permeable outer layer, an absorber, a water-permeable surface layer, left and right waist tapes and front waist tapes. Waist stickers are arranged on the lower surface of the non-water-permeable outer layer, and there are concave arc-shaped gaps in the middle of the trousers body in the length direction and on both sides in the width direction. The arc-shaped cutting device cuts out corresponding arcs, so that the materials in the arcs on both sides are separated from the main body to form a disposable diaper with front and rear side wings. This kind of ...
