Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a wick for a combustion appliance used in a kerosene stove, kerosene stove, etc.

Conventionally, two methods have been proposed for manufacturing cores for oil-burning appliances: one is woven using a loom, and the other is knitted using a warp knitting machine. In both cases, the upper part consists of a heat-resistant combustion wick made of glass fiber or the like, and the lower part consists of a combustible wick made of cotton fiber or the like.

Therefore, constructing the entire structure using the former type of woven structure requires complicated and diverse processes, and has the drawbacks of high cost due to a large amount of material loss, as well as a decrease in fuel absorption rate and evaporation performance during use. When the entire core is made of a knitted structure, the number of weft threads is significantly smaller than that of a woven structure, so when used in a cylindrical shape, the stiffness becomes weak, so it is necessary to attach a thin stainless steel plate or other reinforcing plate for reinforcement. In addition, when the entire core is made into a knitted structure, the lines formed between the holes between each warp yarn are connected in the vertical direction, so when the entire core is suddenly lowered during an emergency fire extinguishment, the internal pressure gas in the tank will be able to move through these lines. The problem was that the flames would flare up abnormally on the equipment because they would be ejected through the combustion chamber and onto the combustion tube.

Therefore, it has been proposed to use a woven, knitted or non-woven fabric as the fuel suction core, and to connect a knitted heat-resistant combustion core to the upper part. This invention relates to an improved invention for processing the tip of the core, and is effective for ignition,
The aim is to improve fire circulation and eliminate various problems caused by tar adhesion.

That is, the method for manufacturing a wick for a combustion appliance of the present invention involves adding a plurality of heat-resistant reinforcing cores to the front and back surfaces of the reinforcing core, which is arranged in parallel with a space of an appropriate width. Warp yarns made of fiber threads bundled to a constant thickness are arranged in a single row or in multiple rows while being repeatedly folded in a zigzag shape in the vertical direction, and these warp rows on the front and back are knitted together with the reinforcing core. Alternatively, by sewing, and then cutting and dividing the front and back warp groups located in the space between the reinforcing cores so that the front and back warp groups are shifted vertically along the longitudinal direction, the cut edges are provided with fluff at different levels. A heat-resistant combustion part wick is formed with two stages of shaped parts, and the other end of each heat-resistant combustion part wick is integrally attached to the upper edge of the fuel suction part wick so that the fluffy part becomes the tip of the combustion part. It is characterized by being connected.

The manufacturing method of the present invention will be explained below with reference to the embodiments shown in the figures. Reference numeral 1 denotes a core body, the upper part has a heat-resistant combustion part core 2 made of a knitted structure, and the lower part has a woven structure, a knitted structure, or a felt-like structure. The formed fuel suction cores 3 made of non-woven fabric or the like are butted together and integrally connected 4 by means such as stitching, and a reinforcing tape 5 is attached to the outer surface (or inner surface) of the connected portion.

The fuel wicking part core 3 is made of cotton fiber or other oil-absorbing fibers, while the heat-resistant combustion part 2 is made of a plurality of reinforcing cores 2a made of heat-resistant paper or the like, as shown in FIG. , 2a' is a space 6 of an appropriate width.
The reinforcing core 2
a, 2a', warp threads 2b, 2b', which are made by twisting or pulling together a plurality of threads of heat-resistant fibers such as glass fibers to a certain thickness, are attached to the front and back surfaces of the warp threads 2b and 2b', respectively, in the longitudinal direction. A plurality of weft yarns 2c, 2c are repeatedly folded in a zigzag pattern, and the overlapping portions of the rows of the warp yarns 2b, 2b', the reinforcing cores 2a, 2a' interposed between them, and other appropriate locations are covered with a plurality of weft yarns 2c, 2c. ' After knitting or stitching at predetermined intervals by chain stitching or other means, the warp groups on the front side of the space 6 are connected to the B line in the longitudinal direction,
The warp yarn group on the back side is cut and divided at offset positions above and below the C line, and each of the edges of each cut section is distributed and arranged in two-staged fluffy sections 7a, 7b, 7c, and 7d. The connecting edges 2d, 2d' of the other edge of the fluffy portion are brought into abutment against the upper edge of the combustion suction portion 3, and the connection 4 is made by suturing or other means so that the fluffy portion becomes a combustion crater. It is.

Figures 7 and 8 show the means for cutting and dividing the weft yarns 2c, 2a', and 2c, with reinforcing cores 2a, 2a' interposed between the row groups of the front and back warp yarns 2b, 2b' as described above. 2c', and a flat rectangular cylindrical guide 8 and a narrow blade receiving plate 9 are installed in the middle part of the guide in the longitudinal direction, and on the left and right of this blade receiving plate. Window holes 1 on the upper and lower surfaces of the guide so that the blades on the periphery can be brought into contact with the lopsided upper and lower surfaces, respectively.
Rotary blades 11 and 1 with shafts corresponding to 0 and 10'
Square tubular guide 8 in cutting tool 12 consisting of 1'
By passing the inside in the direction of the arrow in FIG. 8, the front warp 2b is cut by the rotary blade 11, and the back warp 2b' is cut by the rotary blade 11' at positions along lines B and C, respectively. By cutting and dividing, a heat-resistant combustion core with different cut parts can be obtained.

In addition, various means can be considered for arranging the warp threads 2b and 2b', and in the second illustrated example, two warp thread rows are arranged by repeatedly folding back so as to intertwine with each other. Although this is not shown, a single warp thread row may be arranged in a folded manner, or three or more warp thread rows may be arbitrarily intermingled and arranged in a repeated folded arrangement. It is something. These arrangement means are carried out by a warp knitting machine called a ratchet knitting machine, etc., to arrange the warp threads 2b, 2
b' (when knitted with a knitting machine, it becomes a weft and is repeatedly folded and arranged left and right) is folded and arranged, and the reinforcing core 2a is wound in advance between the folded rows of the warps 2b and 2b', 2a' are sequentially interposed and fed in, allowing continuous knitting with multiple rows of weft yarns 2c and 2c' (which become warp yarns when knitting with a knitting machine). In the next step, in the space 6, it is also possible to continuously process the front and back warp portions by cutting them at different levels at positions along the vertically biased lines B and C, respectively. Thereafter, it may be cut into a certain length and connected to the fuel suction section 3 to form a flat core or a cylindrical core. As another example, as shown in Fig. 6, warp rows on the front and back sides are individually knitted and sewn into multiple rows 2c'' with reinforcing cores 2a and 2a' interposed in the middle, and then cut into uneven pieces. I can do that.

When the manufacturing method of the present invention is used, as described above, the heat-resistant fibers are arranged in a dispersed manner in the longitudinal direction at the tip of the heat-resistant combustion part core 2, which becomes the crater, without the reinforcing cores 2a, 2a' intervening. Since the fluffy portions 7a, 7b (7c, 7d) are formed in two different levels in the vertical direction, the evaporation and suction of the fuel due to capillary action becomes extremely good, improving the combustion characteristics. In addition, in the case of Utility Model Application Publication No. 56-47325, which has only a single row of this fluffy part, that is, in FIG. A core for a combustion appliance is shown in which threads of heat-resistant fibers are arranged in the vertical direction and then cut and divided in the middle so that the threads on one side are slightly protruded from the upper edge of the other thread along with the core. However, this means that the threads that protrude from the upper edge of the center core and form the fluffy portion are only in one stage. However, when using the method of the present invention, the warp groups on the front and back sides of the reinforcing core that protrude from the upper part of the reinforcing core are formed in two stages with upper and lower steps being different. Since the lower part is thinner than the lower part, there is less heat capacity at the time of initial ignition, and fire rotation occurs quickly, stabilizing all-round combustion, shortening the time until red hot, and achieving uniform combustion. This has the advantage of preventing bad odors, eye irritation, and the generation of oily smoke, and in addition, the excess fuel evaporates and burns smoothly without accumulating in the fluffy part 7a (7c) at the tip of the wick, resulting in long-term combustion. In addition to achieving stable combustion, it is also possible to prevent the formation of tar due to thermal decomposition of excess accumulated fuel, and to suppress the generation of carbon monoxide.

Moreover, since it can be formed by simply cutting into different levels during cutting, it not only prevents material loss and scattering of cutting waste, but also has the advantage of saving resources and energy.
