Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a kerosene stove wick for use in a kerosene stove.

Conventional methods for producing cores for kerosene stoves include using heat-resistant fiber as the material, knitting this using a ratchet knitting machine, etc., cutting it and sewing it into a cylindrical shape, or knitting and weaving it into a cylindrical shape from the beginning. It was manufactured by cutting, cutting, etc.

Recently, cores have been used that are made mainly of heat-resistant fibers such as ceramic fibers, which are made into paper-like sheets, wound, formed into a cylindrical shape, coated with an inorganic adhesive, and solidified. It's starting to look like this.

The cores made of these two different materials each have their own characteristics and are used depending on the stove application, but the heat-resistant core made of ratcelle knit fabric has good shape retention because it is a knitted fabric. It is difficult to keep the upper edge horizontal when it is attached to the outside of the inner cylinder of the stove body and moved up and down.
For this reason, the size of the flame varies after ignition, and the size of the flame tends to be uneven, and there are drawbacks such as soot caused by excessive flame in some areas and uneven firepower.
Therefore, reinforcing sheets are used by gluing or sewing them on the inside and outside or on both sides.

Ceramic sheet cores, on the other hand, have very good shape retention properties, but have the drawback of being vulnerable to external forces, especially when folded, and easily damaged during vertical movement of the core.

The present invention provides a stove core that compensates for the advantages and disadvantages of the two by inserting a core sheet into a portion of the core of a heat-resistant thick knitted fabric using a double lattice knitting machine and eliminates the drawbacks of the conventional stove core. The purpose is to

Next, the structure of the present invention will be explained with reference to the drawings. Fig. 1 is an external perspective view of a stove wick according to the present manufacturing method, where 1 is a combustion wick and has a cylindrical shape, and 2 is a lower part of the combustion wick 1. This is a wicking core that is knitted or sewn together.

The combustion wick 1 and the suction wick 2 are knitted by a double lattice knitting machine, but due to the characteristics of the double lattice knitting machine, it is possible to freely knit them into double or single knitting.

In the present invention, from the upper edge of the combustion wick 1,
Double knit over a certain width below the millimeter.

After inserting a core 4 made of a ceramic sheet or the like into this part to form a core insertion part 3, the core is fixed by sewing this part, and this knitted fabric is cut to form a cylindrical shape. It is sewn together to produce stove cores.

At this time, the yarns of the double portion of the core insertion portion 3 are braided using only the warp yarns and no weft yarns, so as to have a so-called sagging shape. This allows you to insert the core and knit at the same time.

Fig. 2 is a longitudinal cross-sectional view of the present stove wick, and Fig. 3 is a partial perspective view, showing the situation in which the core 4 is inserted into the center of the core insertion portion 3 formed in the shape of a blind. It is.

As described above, the present invention first uses a double lattice knitting machine to simultaneously knit the heat-resistant fabric part 1 and the oil-wicking part 2, each of which is double-knitted over a certain width, and then to attach a ceramic sheet, etc. to this double part. Insert a core made of 200% polyurethane to form a core insertion part 3, and after sewing several threads of this part with a sewing machine, cut the knitted fabric to a certain width and sew it into a cylindrical shape to produce a stove core. It is something to do.

In this case, the material used for the core 4 may be, in addition to the ceramic paper described above, non-woven fabric made of glass fiber or the like, or special paper (wood pulp hardened with resin or craft paper), which are suitable for use in stoves. Select and use a wick with appropriate thickness and oil absorption capacity depending on the intended use.

Since the present invention is manufactured as described above, unlike the conventional single knitting method, in which it was impossible to knit the center core at the same time, the double lattice machine allows the center core to be knitted at the same time. Since it is possible to knit continuously by knitting, it is suitable for mass production, it is possible to save a large amount of man-hours, and it can be provided at low cost.

In addition, the stove wick completed using this manufacturing method is
Since the core 4 with an appropriate amount of oil absorption is inserted into the core insertion part 3, it is possible to manufacture a core with an oil absorption amount that is most suitable for the performance of the stove. The presence of the wick improves the shape retention of the wick, and when attached to the inner cylinder of the stove body, the upper end of the combustion section is kept horizontal, and even when the wick moves up and down, the balance can always be maintained. This has the advantage that the combustion flame is even and the disadvantages of uneven firepower and soot caused by excessive flame are eliminated.

Therefore, it is possible to provide the wick most suitable for the function of the stove at a low cost.

Claims (1)

[Claims] 1. An insertion part of a knitted fabric made by knitting a certain part of a heat-resistant thick knitted fabric knitted by a double lattice knitting machine into a double knitting pattern without weft threads, and inserting the core 4 between these double knittings at the same time. A wick for an kerosene stove is made by sewing several strips of wick with a sewing machine, then cutting it to a certain width, sewing it into a cylindrical shape, and forming a core insertion part 3 slightly below the upper end of the sintered wick 1.
