Description

[Detailed Description of the Invention] The present invention relates to a heat treatment device for synthetic fiber yarn using a heat pipe.

Conventionally, heat treaters for synthetic fiber yarns have either had a heater attached to the back of a long grafting plate made of a metal with relatively good thermal conductivity, such as aluminum, or have a sheathed wire heater cast in aluminum. The heat generated from the heater is transferred to the surface of the suction plate via the aluminum plate,
This is an attempt to make the surface temperature of the grafting plate uniform by utilizing the heat conduction of the aluminum plate.

However, with the heat conduction of the aluminum plate alone, it is difficult to buffer the uneven heat generation of the heater or to supply heat to the welding parts at both ends of a rigid grafting plate. The heat treatment effective length of the running yarn becomes shorter than the specified vehicle distance, and the surface temperature of the suture plate is not always uniform.

In this invention, a heat pipe with a thermal conductivity of pure copper, which has a thermal conductivity of 500, is installed along the heater and the splicing plate to buffer uneven heating of the heater, and to supply heat to the spliced parts at both the upper and lower ends of the weld. The feature is that the effective length of the thread plate is large and the surface temperature of the graft plate is made uniform.

The present invention will be described below with reference to the drawings.

FIG. 1 is a plan sectional view showing a conventional embodiment, and FIG. 2 is a front view of FIG. 1 and a temperature distribution diagram on the surface of the suture plate.

As can be seen from FIGS. 1 and 2, conventionally, a heater 4 is pasted or a sheathed wire heater is cast into a bonding plate 1 made of a metal with relatively good thermal conductivity, such as aluminum. The effective heat-generating section of thread plate 1 in the longitudinal direction of the vehicle is extremely short.

FIG. 3 is a plan sectional view showing an embodiment of the present invention, and FIG. 4 is a front view of FIG. 3 and a temperature distribution chart on the surface of the grafting plate. A long groove 3 is provided to insert and fix the pipe 2, the heat pipe 2 is fixed in the groove 3, and a heater 4 is stuck on the heat pipe 2.

That is, the heat generated from the heater 4 is transferred to the heat pipe 2.
Since the heat pipe 2 has high thermal conductivity, the temperature is uniform regardless of uneven heating of the heater 4, and heat is supplied to the splicing plate 1 through the uniformly heated heat pipe 2. The temperature of the grafting plate 1 becomes uniform.

In addition, heat is sequentially supplied from the heat pipe 2 to the upper and lower ends of the suture plate 1, which emit a large amount of heat, and the effective length of the suction plate 1 is extended.
