Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a method for manufacturing wicks for combustion appliances such as kerosene stoves and kerosene stoves that use kerosene as fuel.

《Prior art》 In the conventional manufacturing method of this type of wick for combustion appliances, a thick fabric such as glass fiber or a blend of glass fiber and carbon fiber is attached to the upper part of the fuel suction part made of cotton yarn or a thick fabric of a blend of cotton and rayon. It is known to form a flat or cylindrical core body to which a heat-resistant combustion part is connected.

In addition, thick warps made by simply bundling or twisting glass, cotton, or other fibers are arranged horizontally, and a felt-like fiber layer of glass fiber is polymerized on both the front and back sides, and the glass fibers in the felt-like fiber layer are formed by needle punching. It is known, for example, from Japanese Patent Publication No. 49-36170 to make a wick for a combustion appliance by intertwining it with thick warp threads arranged in parallel laterally.

<<Problems to be Solved by the Invention>> However, the former method of manufacturing wicks for combustion appliances had the following drawbacks.

(1) Productivity is extremely low and inefficient because production relies on old-fashioned special looms.

(2) In particular, the fuel suction section is made of very thick cotton yarn, such as 10 count 8-strand yarn, as the warp, and is narrow and has a special structure, so the number of looms is limited.
Furthermore, because the area used is large, there is often a shortage of supply.

(3) Dimensional variations are likely to occur, resulting in a high defective rate, and in addition to shrinking during use, the device's core guide tube is likely to get stuck, leading to problems such as improper lifting and lowering of the core.

(4) It tends to fray when cut, so it is necessary to apply fraying prevention processing such as overstitching the edges or applying adhesive.

(5) Fuel suction efficiency deteriorates due to interlacing of warp and weft threads.

(6) Due to the weaving, the surface is uneven, and there are gaps between the warp and weft yarns, which makes it difficult to adhere tightly to the core guide tube of the device, creating an unnecessary draft effect between the inside of the tank and the outside air. Not only does it impair combustion performance and fire extinguishing performance, but it also increases oil leakage when equipment falls over.

To obtain the latter wick for combustion appliances, a felt-like fiber layer of glass fiber is simply bundled with glass, cotton, or other fibers, or thick warp threads made by twisting are arranged horizontally, polymerized on both the front and back sides, and then needles are formed. Since the glass fibers of the felt fiber layer are entwined with the horizontally parallel thick warp threads by punching, the adjacent thick warp threads are separated, and further the parallel thick warp threads and the felt fiber layer of glass fibers come into contact with or separate from each other. Due to warp warp deformation, dimensional instability when the device is attached, etc., the fuel suction effect is poor and the flame is not evenly aligned.Furthermore, since the wick is not equipped with a fuel suction part, it is difficult to smoothly raise and lower the wick to increase the firepower. There were drawbacks such as the inability to make adjustments and the inability to easily manufacture products with a thickness appropriate for each model.

This invention solves the above-mentioned problems. It can be easily manufactured with a thickness suitable for each model, has good fuel suction efficiency, and can smoothly adjust the firepower by raising and lowering the wick. It is possible to mass-produce non-woven fabric interlining at low cost, and the height (distance) from the liquid fuel level to the combustion part can be reduced.
The purpose is to manufacture wicks for combustion appliances that are convenient to use, such as being able to take a large amount of heat, preventing liquid fuel from being heated to high temperatures, and continuing safe combustion. It is.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the method for manufacturing a wick for a combustion appliance of the present invention involves aligning a large number of long fibers in the longitudinal direction and bonding the long fibers with an adhesive. adhered to each other to form a continuous long fiber fabric band 1 in the form of a band,
Next, several sheets of the long fiber fabric band 1 are overlapped to form a band-shaped long fiber layer band 2, and then the long fiber layer band 2 is interposed inside, and the short fiber random web layer bands 3 are placed on both the front and back sides. The laminated band 4 shown in FIG. A fuel wick 6 is formed in which a large number of long fibers are oriented in the vertical direction, and then the upper end of the fuel wick 6 and the lower end of a heat-resistant combustion wick 7 are connected to form a core body 8. .

<<Example>> Hereinafter, an example of the present invention will be described with reference to the drawings. 1 is a continuous long fiber fabric band in the form of a belt by aligning a large number of long fibers in the longitudinal direction and bonding the long fibers to each other via an adhesive. It is. Reference numeral 2 denotes a long fiber layer band in the form of a belt formed by overlapping several sheets of the long fiber fabric band 1. Reference numeral 4 designates a laminated band 4 in which a long fiber layer band 2 is interposed and short fiber random web layer bands 3, 3 are exposed on both the front and back sides. 5 is a fuel wicking core band formed by polymerizing and integrating the laminated band 4 by needle punching. Reference numeral 6 denotes a fuel wicking core in which the fuel wicking core band 5 is cut and a large number of aligned long fibers are oriented in the vertical direction. 8 is a core body formed by connecting the upper end of the fuel wick 6 and the lower end of the heat-resistant combustion wick 7.

The short fiber random web layers 3, 3 are formed so as to appear on the front and back sides of the fuel wicking core band 5, and as shown in FIG. Several layers of fiber random web layers 3 may be polymerized alternately.

Further, the long fiber layer band 2 and the short fiber random web layers 3, 3 are polymerized and integrated by entangling the short fibers 9 that have formed the short fiber random web layer 3 by needle punching.

The long fiber material forming the long fiber fabric band 1 may be one of rayon, acetate, nylon, acrylic, polyester, vinylon, polyethylene, polypropylene, glass fiber, polyvinyl chloride, aramid, and carbon fiber, either alone or in combination. Can be done.

The materials of the short fiber random web layer 3 include rayon, acetate, nylon, acrylic, polyester, vinylon, polyethylene, polypropylene, glass fiber, polyvinyl chloride, aramid,
Carbon fiber, cotton, linen, wool, etc. may be used alone or in combination.

Also, fine wall gaps 10, 10, . . . are formed between the superimposed long fiber fabric bands 1, 1, . . . to facilitate the absorption of fuel.

The production of the fuel wicking core band 5 will be explained with reference to FIGS. 7 and 8. The long fibers are pulled out from several first rolls 11, 11, around which the long fiber fabric band 1 is wound. A layered band 2 is formed, and short fiber random web layered bands 3, 3 are pulled out from the second rolls 12, 12 to form a laminated band 4, which is needle-punched by a needle machine 13 and attached to a needle. By breaking through the laminated band 4, the short fibers 9 of the short fiber random web layer 3 are entangled with the long fiber layer band 2, forming the fuel wicking core band 5.
is formed and wound around the rotating body 14.

Further, the core body 8 can be used as a flat core in the form of a flat plate or as a cylindrical core.

<<Actions and Effects of the Invention>> According to the present invention, the following effects can be obtained.

(1) Since interlining can be produced at high speed without the need for looms, knitting machines, etc., interlining can be obtained with higher productivity and at lower cost than before.

(2) Since the short fiber random web layers 3, 3 are provided and made of non-woven fabric, the fuel wick 6 does not fray at the cut end when it is formed, and can be manufactured uniformly without variations in dimensions.

(3) Since the short fibers are randomly intertwined, the claws of the core holding tube can be accurately locked without damaging the fibers, so dimensional deviations do not occur during use.

(4) The fuel wicking core 6 is a long fiber layer band 2 in which a large number of long fibers are arranged vertically and are made by polymerizing several long fiber fabric bands 1 that are bonded to each other via an adhesive.
Since the short fiber random web layers 3, 3 are interposed inside and appear on the surface, and the lower end of the heat-resistant fiber core is bonded to the upper end of this layer, fuel is sufficiently supplied to the heat-resistant fiber core 7, so that it can generate high heat. can be obtained.

(5) The fuel wicking core 6 in which the long fibers are oriented in the vertical direction has the same effect as having a large number of capillary tubes running above and below, and has a high fuel wicking speed, thereby generating a high amount of heat. Furthermore, since it is possible to increase the height between the liquid level of the liquid fuel in the fuel tank and the combustion part, it is possible to avoid the risk of the liquid fuel in the fuel tank being heated to a high temperature. .

(6) The long fiber layer band 2, which is made up of a large number of long fibers bonded together with an adhesive, facilitates fuel uptake, but since the fibers do not intertwine with each other, they tend to tear easily. layer 3,3
When polymerized and integrated by needle punching, the short fibers 9 of the short fiber random web layer 3 are entwined with the long fiber layer band 2, making it strong and preventing dimensional variations due to dimensional changes during use. Trouble can be eliminated.

(7) In combustion appliances with a fuel tank located at the bottom, as the combustion time increases, even if the fuel level in the fuel tank decreases, the amount of fuel absorbed will decrease, and the firepower will not weaken.

(8) The laminated belt 4 in which the long fiber layer band 2 is interposed inside and the short fiber random web layers 3 and 3 are exposed on both the front and back sides can be created by changing the number of laminated layers of the long fiber fabric band 1. It is possible to easily form the core body 8 whose thickness can be changed and the thickness and suction amount can be obtained depending on the model.

(9) When the long fiber layer band 2 formed by overlapping several long fiber fabric bands 1 is formed into the fuel wicking core 6, there is a fine wall gap between the adjacent long fiber fabric bands 1, 1... Gaps 10, 10, . . . are formed, and a capillary phenomenon occurs to promote fuel suction.
