Buckling process for disposable absorbent article fixed patches

Abstract

The invention relates to the producing and manufacturing field of disposable absorbent articles, in particular to a buckling process for disposable absorbent article fixed patches. The buckling process is simple in operation mode, and capable of effectively enabling the fixed patches to be buckled tightly and enabling the fixed patches not to be separated easily in production. The buckling process includes the first step of tucking up the fixed patches of the produced disposable absorbent articles, then pressing down the fixed patches by means of a pressing plate, and enabling buckling bodies of two pairs of opposite fixed patches to be buckled with plush faces, the second step of inputting the disposable absorbent articles to a twisting device, conveying the disposable absorbent articles through the twisting device, enabling the upper surfaces and the lower surfaces of each pair of fixed patches of the disposable absorbent articles to carry out relative displacement movement by means of the twisting motion of the twisting device, namely, each buckling body generates the relative displacement movement with the plush faces, wherein the time of the relative displacement movement is 0.05-0.5 second, and then continuing to convey the disposable absorbent articles, and the third step of outputting the disposable absorbent articles from the twisting device and inputting the disposable absorbent articles to a folding process.

Description

technical field [0001] The invention relates to the field of production and manufacture of disposable absorbent articles, in particular to a fixing and fastening process of disposable absorbent articles that makes the fastening and fastening of disposable absorbent articles tighter. Background technique [0002] At present, disposable absorbent articles are still in the form of sheets in the final production process, and they are usually folded in order to save space and make packaging more convenient. And when folding, due to the existence of the fixed sticker on the waist side of the disposable absorbent article, in order not to expose the fixed sticker to the disposable absorbent article and damage it, and in order not to make shaking become an obstacle to subsequent folding and packaging, it is usually necessary to put the The buckle body of the fixing patch is fastened to the plush surface of the corresponding fixing patch. This method of fastening the fixing patch by u...

Problems solved by technology

However, in actual production, because the pressing plate is front pressed so that the button body and the plush surface fit together, it is often impossible to fasten, and the fixing sticker will open again because it cannot be fastened, which will become an obstacle to subsequent folding and packaging, and may even cause problems. Unfastenable, unfastenable due to damage from exposure to disposable absorbent articles

like figure 1 As shown, the button body 91 includes a flat plate 911, a plurality of hook bodies 912 evenly distributed on the flat plate 911, and the plush surface 92 includes a flat plate 921, and velvet yarns 922 interlaced on the flat plate, when the button body and the plush When the surface is fitted, the hook body is inserted into the wool and hooked so that the button body and the plush surface are fastened, but if it is only a simple fit, such as figure 2 As shown, when the hook body 912 is inserted, its barb part will squeeze the wool 922, so that a large part of the plurality of hooks still does not catch the wool, so that the fastening force is reduced, so that the button body and the plush Surface is easier to separate
