JPS6122125A - Manufacture of gas lighter wick - Google Patents

Abstract

PURPOSE:To contrive to manufacture the wick having the uniform property and excellent flame stability under the high speed and less noise manufacturing process by a method wherein a powdered wick material is treated by an ultrasonic vibration for designated time length, then the wick is formed by heating and sintering. CONSTITUTION:Many wick-shaped packing chambers 11 are bored on a metal mold 10, the metal mold 10 is contained in a metal vibrating case 12. After a powder receiving frame 13 is mounted on the metal mold 10, a polyethylene powder (80-300 mesh) is dropped from a hopper 14, the powder is filled in the packing chamber 11. In this case, an ultrasonic vibration member (horn) 15 is abutted with the lower part of the vibrating case 12, for instance, 18kHz ultrasonic vibration is given for 6-10min. By utilizing the ultrasonic vibration without using the mechanical vibration, the noiseless filling can be performed. Thus, the wick is manufactured by sintering the filled powder.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a fuel wick for a gas lighter using liquefied fuel.

(Prior art) Conventionally, the wick of a gas lighter is made by filling a mold with poly-1-dylene powder (by applying mechanical vibration to increase the filling surface,
It was then manufactured by heating and sintering and shaping it, but with this method, the filling surface of the powder becomes uneven, and the liquefied gas is not drawn up uniformly during suction, which often results in unstable flames. There was a problem. In addition, during mass production, it took about 20 seconds to vibrate the melons, which limited the speed of production.

In addition, there was a problem in terms of the manufacturing environment, as the noise was too loud when mechanical vibrations were applied.

(Purpose of the Invention) The present invention is a patent characterized by providing a method for manufacturing a gas lighter wick that is homogeneous and has good flame stability at high speed and with low noise, in view of the problem mentioned in the following. .

(Structure of the Invention) The method for producing a gas lighter wick according to the present invention involves applying ultrasonic vibration to the powder for a predetermined period of time when filling a mold with powder of a core material such as polyethylene, and then heating and sintering the core material. It is characterized by molding.

(Effects of the Invention) According to the manufacturing method of the present invention, it is possible to uniformly fill the core material powder in an extremely short time (about 6 to 10 seconds) using ultrasonic vibration, so a homogeneous core can be formed at high speed. , can be manufactured. Moreover, since it uses ultrasonic waves instead of mechanical vibrations, it enables quiet filling without noise, and it also improves the manufacturing environment. Furthermore, it does not damage the mold as compared to mechanical vibration, and greatly contributes to the lifespan of the mold and, ultimately, to the reduction of costs.

(Example) As shown in FIG. 1, a mold 10 in which a large number of core-shaped filling chambers 11 are bored is housed in a metal vibrating case 12, and a powder quantity frame 13 is mounted on top of the mold 10. , polyethylene powder (80 to 300 mesh) is dropped from the hopper 15 to fill the filling chamber 11 with the powder.

At this time, an ultrasonic vibrator (horn) 15 is brought into contact with the vibrating case 12 from below, and ultrasonic vibration of, for example, 18Kl-(Z) is applied for 6 to 10 seconds. The core 20 is manufactured by sintering according to the method.

As shown in FIG. 2, a 3 mm portion of the lower end of the core 20 thus produced was immersed in liquefied gas, and the suction speed was measured. The measurement method was to measure the time taken for alcohol to be sucked up from 5 mm to 15 mm from the bottom. (Room temperature: 20°C) The results are not shown in the table below.

As seen in the table above, the difference (R) between the maximum (MAX, ) and minimum (M I N ) due to mechanical vibration is 4
．． 08 seconds, but with the present invention it was 2.7 seconds.
It was found that the suction time was as short as 8 seconds and that the suction was stable.

This has a close relationship with the stability of the flame upon ignition, and the wick manufactured according to the present invention is effective in putting a lighter with a stable flame into practical use.
