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

A kind of technology for making oversleeve

Technical field

The present invention relates to a kind of amenities production new technique, particularly a kind of technology for making oversleeve.

Technical background

Manual welding or stitching process are adopted in existing oversleeve production mostly, and the wherein manual welding technological process of production is: tubular fracture → be inserted in supporter → buckle into elastic ring → flange → electric iron solder up → change is nose heave multiple.The sewing technological process of production is: lining fracture → tubular moulding → buckle into elastic ring → flange → sewing is sealed → changes one nose heave multiple.There are many drawbacks in its technology: (1) precision is not high, material is difficult for smoothly, easily produces and seals not prison welding, weldering is broken, wrinkling or sewing misplaces, and directly influences product quality.(2) owing to artificial multiple working procedure manual operations, product is difficult to meet the disposable product hygienic requirements.(3) production efficiency is low, causes human capital to substantially exceed the raw material capital.(4) production environment is polluted, and directly damages workman's health owing to long-time closely hand-held flatiron, sootiness.What sewing machine brought then is the working strength of workers height, the eyes fatiguability.

Summary of the invention

The present invention is intended to efficiently, health, guarantee the quality, under the prerequisite of production of safety, fully-automatic production goes out the oversleeve of super quality and competitive price, to satisfy growing social demand.

A kind of technology for making oversleeve of the present invention is achieved in that two side rib collar elastic rings of this oversleeve are circles that is synthesized by the Ω shape elastic of two symmetries, and the two side rib collar elastic number of turns of this oversleeve can be one or several compositions; Sleeve is a cylinder that is synthesized by the Ω shape plane lining of two symmetries, and its lining is to contain Chemical fiber component at the lining more than 50%; There are two butt welded seams the inboard of this oversleeve, four flange; Elastic is implemented the PUR coating, then implement Plastic Welding, make elastic and lining be adhesively fixed as adopting the braiding elastic band; Two layers of welded lining that has an elastic are carried out butt welding perpendicular to the plane.

The present invention changes the tradition processing theory of people to rib collar elastic circle, with the circle after two straight line elastics, two first groups of butt joints formation expansion, replace existing ring-type elastic ring or the circumference circle that binds off, the linearly operating of original artificial circumference action becoming machinery, its advantage is: the raising of (1) production efficiency, and the automatic assembly line that moves with a middling speed is an example, the output in one sky can be nearly 100,000, it is artificial to support up to a hundred workmans, has changed original labor-intensive production.(2) owing to be the mechanization continuous processing, thus there is not the factor of staff contact product, thus guaranteed the hygienic requirements of product.(3) the finished product rate height that goes out of automated production, quality is guaranteed, can realize automatic flange, packaging integrated, thereby can reduce cost.(4) since the direct labor away from high temperature and power supply point, production environment, labour intensity are improved.(5) to adopt Chemical fiber component content be lining more than 50% in the present invention, adopts thermal spraying or Plastic Welding technology, and product appearance that it is produced and result of use are all very comfortable.

Description of drawings

Fig. 1 is technological process of production figure of the present invention;

Wherein: 1A is a technological process of production front view;

1B is a technological process of production vertical view.

Fig. 2 is the inboard state diagram of oversleeve of the present invention;

Fig. 3 is the two Ω shape composite diagrams of rib collar elastic of the present invention.

Among the figure: 1 and 1 ' is elastic, and 2 and 2 ' is lining, and 3 is flange, and 4 is weld seam.

Embodiment

Now be illustrated in conjunction with the accompanying drawings, show by Figure 1A: with A → B → C movement locus direction, from two dispensing shafts, emit two layers of wide lining 2 and 2 ' synchronously, simultaneously drawing 1 and 1 ', two of eight elastics with equal tension from eight elastic tubes again is one group and echos to constant speed respectively on four edges of two aspect material.Among Figure 1B, elastic 1 and 1 ' is implemented the PUR coating, then can implement Plastic Welding, make elastic and nonwoven lining be adhesively fixed as adopting the braiding elastic band at A and A ' (a and a ') point; B and two layers of lining that has an elastic are carried out butt welding perpendicular to the plane at B ' (b and b ') o'clock, form weld seam 4; The C point then butt welded seam 4 carry out symmetrical center line and cut.Fix → circulation mechanical action that lining butt welding → weld seam is cut with elastic, just can be automatically, continuously produce standard-sized disposable oversleeve (referring to Fig. 2); Two side rib collar elastic rings of this oversleeve are synthetic circles of Ω shape elastic (referring to Fig. 3) by two symmetries.Equally, sleeve also is a synthetic cylinder of the Ω shape plane lining by two symmetries.

Claims

1, a kind of technology for making oversleeve, the two side rib collar elastic rings that it is characterized in that this oversleeve are circles that synthesized by the Ω shape elastic of two symmetries; Sleeve is a cylinder that is synthesized by the Ω shape plane lining of two symmetries, and its lining is to contain Chemical fiber component at the lining more than 50%.

2, a kind of technology for making oversleeve according to claim 1 is characterized in that there are two butt welded seams the inboard of this oversleeve, four flange.

3, a kind of technology for making oversleeve according to claim 1 is characterized in that the two side rib collar elastic number of turns of this oversleeve can be one or several compositions.

4, a kind of technology for making oversleeve according to claim 1 is characterized in that elastic is implemented the PUR coating, then implements Plastic Welding as adopting the braiding elastic band, makes elastic and lining be adhesively fixed; Two layers of welded lining that has an elastic are carried out butt welding perpendicular to the plane.
