次工程でホース端部を加圧し該端部を溶着する。As shown in FIG. 3, the conventional method for closing the end of a hose is to press the tip of the hose (6) against a cone (7) connected to a band heater (8), and then press the end of the hose (6) against the heated cone (7). The inner surfaces of the ends of the hose (6) are brought into contact to melt the inner surface of the hose (6), and the hose (6) is pulled away from the cone (7);
In the next step, the end of the hose is pressurized and welded.

ースでは閉塞端面が美しく仕上がらなかった。[Problem to be Solved by the Invention] When the end of the hose is applied to the heating cone (7), molten resin sludge adheres to the surface of the cone (7), which burns and releases chlorine gas and other substances. Poisonous gas was emitted and the working environment was poor. In addition, the inner surface of the hose may be melted more than necessary, and the molten resin may seep out from the end of the hose during the pressing process, or the sludge on the cone may be pressed while still attached to the inner surface of the hose, which may cause the closed end surface of the hose to become clogged, especially with transparent hoses. It didn't turn out beautifully.

。[Function and Effect] Hot air is injected onto the inner surface of the end of the hose (6) to heat and melt the inner surface of the end, so unlike conventional methods, molten resin sludge does not adhere to the heating cone (7). Therefore, the generation of toxic gas due to combustion of molten sludge can be suppressed, and a clean working environment can be maintained.

Because there is no such thing, the blocked part of the transparent hose looks especially beautiful.

ある。When the hose (6) is placed on the hose holder (5), the axes of the injection tube (2) and the hose (6) are aligned.
The height of the pedestal (5) relative to the injection barrel (2) can be adjusted.

The inner surface of the hose tip is heated and melted by hot air jetted from the nozzle hole (3) on the outer periphery of the hose tip.

えることができ、クリーンな作業環境を維持できる。Since hot air is injected onto the inner surface of the end of the hose (6) to heat and melt the inner surface of the end, molten resin sludge does not adhere to the heating cone (7) as in the conventional case. Therefore, the generation of toxic gas due to combustion of molten sludge can be suppressed, and a clean working environment can be maintained.
