Problems solved by technology

There are many disadvantages in its process: (1) The precision is not high, the material is not easy to be flat, and it is easy to cause weak sealing welding, welding breakage, wrinkling or sewing misalignment, which directly affects product quality
(2) Due to the manual operation of multiple manual processes, it is difficult for the product to meet the hygienic requirements of disposable products
(3) Low production efficiency, resulting in human capital greatly exceeding raw material capital
(4) The production environment is polluted, because the long-term short-distance hand-holding of the soldering iron and the smoke directly damage the workers' health
What the sewing machine brings is that the labor intensity of the workers is high, and the eyes are prone to fatigue.

Embodiment Construction

[0013] Now in conjunction with the accompanying drawings to illustrate, according to figure 1 A shows: in the direction of A→B→C motion trajectory, two layers of equal-width fabrics 2 and 2' are simultaneously released from the two unwinding axes, and eight elastic bands with the same tension are drawn out from eight elastic tubes at the same time 1 and 1', two as a group are attached to the four edges of the two-layer fabric at a constant velocity. figure 1 In B, apply hot melt adhesive to the elastic bands 1 and 1' at points A and A' (a and a'). If a braided elastic band is used, plastic welding can be implemented so that the elastic band is bonded to the non-woven fabric. at points B and B' (b and b'), butt-weld the second layer of fabric with elastic perpendicular to the plane to form weld 4; cut. The circular mechanical action of elastic fixing → fabric butt welding → welding seam cutting can automatically and continuously produce standard-sized disposable sleeves (see ...

Abstract

The present invention relates to a new production process of sleeve protector, and is characterized by that the rib cuff elastic ring of each of two ends of said sleeve protector is a circular ring synthesized by two symmetrical notched rubber bands, and the number of the rib cuff elastic rings can be one or several bands, and said sleeve is a cylinder synthesized by two symmetric notched plane face fabrics, and the internal side of said sleeve protector has two but-welded seams and four folded selvages, and the rubber band and face fabrics can be adhered and fixed together by adopting the processes of collosed coating and plastic welding, so that the original traditional manual circumferential movement can be changed into the invented mechanical linear movement so as to raise its production efficiency.

Description

technical field [0001] The invention relates to a new technique for producing sanitary products, in particular to a new technique for processing sleeves. technical background [0002] Most of the existing cuff production adopts manual welding or sewing technology, and the manual welding production process is as follows: cylindrical cutting → inserting the support → buckling the elastic ring → flanging → welding and sealing with an electric soldering iron → changing one end and repeating. The sewing production process is as follows: fabric cutting → tube forming → buckle into the elastic ring → flanging → sewing and sealing → change one end and repeat. There are many disadvantages in its process: (1) The precision is not high, the material is not easy to be flat, and it is easy to cause weak sealing welding, welding breakage, wrinkling or sewing misalignment, which directly affects product quality. (2) Due to the manual operation of multiple manual processes, the product is ...
