Description of the Related Art A conventional belt vulcanizing apparatus, as shown in FIG. 6, shows an inner hollow molding mold 2 having an unvulcanized belt sleeve 1 mounted on its outer peripheral surface, and an elastic material on its outer peripheral surface. A deformable cylindrical jacket 3 is concentrically fitted, and the assembly assembled in the above-described form is installed on a supporting table 5 located in the lower part of the vulcanizing can 4 via an elastic packing material 9, and further molded. Place the top lid 6 on the mold 2 for
High pressure steam is injected into the outside of the molding mold 2 and low pressure steam is injected into the inside of the mold to form the unvulcanized belt sleeve 1
It has a structure for vulcanizing. Both the high-pressure steam and the low-pressure steam are introduced through the inlet 7, and the water inside is discharged through the drain port 8.

の良いベルトスリーブを得ることにある。In the above belt vulcanizing apparatus, high-pressure steam on the outside of the jacket presses the jacket, and then presses the unvulcanized belt sleeve to discharge the air existing in the gap between the jacket and the molding mold. The object is to obtain a high-quality belt sleeve by molding and solidifying rubber into a predetermined shape and making it dense without bubbles.

生した。However, in the conventional vulcanizing apparatus, the airtightness between the jacket and the upper lid is improved, the seal between the jacket and the upper lid is enhanced, and high-pressure steam is prevented from entering the inside of the jacket. are doing. If the high-pressure steam penetrates into the jacket, the core made of glass fiber deteriorates and the function of the belt is impaired.

衡に達し、結果として気泡を内在したベルトスリーブが
成形された。For this reason, in order to improve the airtightness between the jacket and the upper lid, if the amount of air contained in the space between the jacket and the molding mold increases, the high-pressure steam outside the jacket will pass through the jacket. Even if the unvulcanized belt sleeve was pressed to remove the air existing between the jacket and the molding mold, the pressure reached an equilibrium in an insufficient state, and as a result, a belt sleeve containing bubbles was formed.

得る加硫装置も提案された。In order to prevent this, the upper lid and the wall of the vulcanization can are connected by a pipe, and the air contained therein is discharged into the atmosphere outside the vulcanization can to give sufficient vulcanization pressure to the unvulcanized belt sleeve. A vulcanizing device has also been proposed, which obtains a high-quality belt sleeve that does not contain bubbles and is dense.

内に侵入し、心線が劣化する問題が発生した。However, even in this vulcanizing apparatus, since the pipe connecting the upper lid and the vulcanizing can wall is constantly exposed to high-temperature and high-pressure live steam, it has been severely corroded and must be replaced frequently. Further, even if a hole is formed in the pipe due to corrosion, there is a problem that it is difficult to visually detect depending on the size. Further, when the pipe replacement time is delayed, high-pressure steam penetrates into the unvulcanized belt sleeve inside the jacket through a hole opened due to corrosion, which causes a problem of deterioration of the core wire.

加硫装置を提供することを目的とする。The present invention solves such a problem, and not only a sufficient vulcanizing pressure can be obtained even if there is air in the gap between the jacket and the molding mold, but a large number of vulcanizations can be performed at one time. An object of the present invention is to provide a belt vulcanizing device which can easily obtain an unvulcanized belt sleeve and can obtain a high quality belt sleeve containing no bubbles.
