Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat-

The present invention relates to a hot air heater for heating a fiber reinforcing material yarn, and more particularly, to a hot air fan for heating a fiber reinforcing material yarn capable of heating a drawn yarn for producing a fiber reinforcing material in order to maintain an existing strength.

The temperature of the yarn is lowered in the winter season when the fiber reinforcement is produced. In this case, when the product is made from a lowered temperature yarn, the strength decreases by about 10%. Thus, fiber yarn is further withdrawn to produce the fiber reinforcement to meet the desired strength. Therefore, there is a problem that the cost is increased because the yarn is further consumed.

Published Patent No. 10-2003-0078809 (published on October 10, 2003) Published Japanese Patent Application No. 10-2013-0045440 (Publication date 2013.05.06)

The present invention is intended to solve the above problems. It is an object of the present invention to provide a hot air fan for heating a fiber reinforcing material yarn which can prevent a drop in strength by heating a yarn of a fiber reinforcing material even if the fiber reinforcing material is produced in the winter season.

The hot air fan for heating fiber reinforcing material according to the present invention includes a housing, a heating means, a blowing means, a prevention plate, and a discharge means. The heating means includes a first heating coil vertically installed in the lower portion of the housing, and a second heating coil disposed in the housing in a plurality of stages horizontally at an upper portion of the first heating coil. The blowing means supplies air into the housing through the lower end of the housing. The prevention plate is installed below the first heating coil to prevent wind supplied from the blowing means from directly contacting the first heating coil. The discharge means includes a first discharge passage extending from the housing and guided so that air in the housing is discharged to the upper portion of the fiber reinforcing material yarn, and a second discharge passage extending from the housing to discharge air inside the housing to the lower portion of the fiber reinforcing material yarn And a second discharge passage guided so as to be opened.

It is also preferable that the hot air fan for heating the fiber reinforcing material yarn further includes a cylindrical cap having a top opened and a plurality of holes formed in the circumferential surface thereof to surround the first heating coil.

According to the present invention, the yarn of the fiber reinforcing material can be heated at a falling temperature in the winter, thereby preventing further addition of yarn in the production of the fiber reinforcing material.

In addition, according to the present invention, since the hot air is provided with the prevention plate, it is possible to prevent the wind from the blower from being directly supplied to the heating means. In this case, it is possible to prevent the air from being exhausted even before the air is properly heated by the heating means, so that the efficiency of heating can be increased.

In addition, according to the present invention, since the cap is provided to enclose the first heating coil, the air can be sufficiently heated inside the cap, thereby increasing the efficiency of the hot air.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a conceptual diagram of an embodiment of a hot air fan for heating a fiber reinforcing material yarn according to the present invention;
FIG. 2 is a conceptual view of the interior of the housing of the hot air fan shown in FIG. 1. FIG.

1 and 2, an embodiment of a hot air fan for heating fiber reinforcing yarn will be described.

The hot air for heating the fiber reinforcing material yarn according to the present invention includes the housing 10, the heating means 12, the cap 15, the blowing means 20, the prevention plate 22 and the discharge means 25 do.

The heating means 12 is provided inside the housing 10 and serves to heat the air supplied from the blowing means 20. To this end, the heating means 12 comprises a first heating coil 13 and a second heating coil 14. The first heating coil 13 is vertically installed in the lower portion of the housing 10. This is arranged in the flow direction of the air supplied from the blowing means 20 so as to heat the air for a long time. The second heating coil 14 is installed horizontally in a multi-stage on the upper portion of the first heating coil 13. In this embodiment, the second heating coil 14 is installed in two stages.

The cap 15 serves to enclose the first heating coil 13 in order to sufficiently heat the air to the first heating coil 13. For this purpose, the cap 15 is formed in a cylindrical shape with an opened top, and a plurality of holes are formed in the outer circumferential surface of the cylindrical shape, and the first heating coil 13 is accommodated in the outer periphery of the cylindrical shape to surround the first heating coil 13. The air can be introduced into the hole of the circumferential surface of the cap 15 and heated by the first heating coil 13 and then discharged into the upper open passage.

The blowing means 20 is installed in the housing 10 so as to supply air into the housing 10 through the lower end of the housing 10.

The prevention plate 22 prevents the air supplied from the blowing means 20 from directly contacting the first heating coil 13 and the first heating And is installed at the lower portion of the coil 13. This is because the air supplied from the blowing means 20 has a high velocity and can be directly discharged to the outside before the air is sufficiently heated if it directly contacts the first heating coil 13. [ The air supplied from the blowing means 20 first comes into contact with the prevention plate 22 and then is dispersed around and flows to the first heating coil 13. [

The discharging means 25 serves to guide the air to heat the yarn 1 of the fiber reinforcing material with the air heated inside the housing 10. [ To this end, the discharge means 25 has a first discharge passage 26 and a second discharge passage 27.

The first discharge passage 26 extends from the housing 10 so as to discharge air to the upper portion of the fiber reinforcing yarn 1 and the second discharge passage 27 discharges air to the lower portion of the fiber reinforcing material 1 And extends from the housing 10 so as to be discharged. That is, in the housing 10, the air is heated by the heating means 12 and the heated air is discharged to the upper and lower portions of the yarn 1 through the first discharge passage 26 and the second discharge passage 27 And the yarn 1 is heated.

In this embodiment, when the air blowing means 20 is operated, air is supplied from the lower portion of the housing 10 to the inside. The air supplied to the inside of the housing 10 first collides with the restraining plate 22. The air impinging on the prevention plate 22 is dispersed and guided to the first heating coil 13. [ The air supplied from the air blowing means 20 is directly guided to the first heating coil 13, but in this case, the flow speed of the air is high, so that the air is blown out before being sufficiently heated by the first heating coil 13 Can be discharged to the means (25). In this embodiment, the air is first heated by the first heating coil 13 because it collides with the prevention plate 22 and is guided to the first heating coil 13. On the other hand, in the case of the first heating coil 13, a hole is formed so as to be surrounded by the cap 15 and air can be supplied to the inside of the cap 15, so that the air guided to the first heating coil 13 passes through the cap 15 And is supplied to the first heating coil 13 through the hole of the first heating coil 13. At this time, the air is sufficiently heated inside the cap 15 and supplied to the second heating coil 14 through the upper end of the cap 15. The air heated in the second heating coil 14 is discharged to the yarn 1 through the first discharge passage 26 and the second discharge passage 27. Thus, the yarn 1 can be heated.

In the winter season, the temperature of the external environment is lowered, and the strength of the yarn is lowered. If the yarn is heated by using the hot air of the present embodiment, the strength of the yarn can be prevented from being lowered, Can be prevented.
