Rubber continuous vulcanization system

Abstract

The present invention provides a continuous rubber vulcanization system which can perform inspection and work while preventing scattering of vulcanization gas, and has excellent heat preservation performance. In a rubber vulcanizing furnace (11, 12) in which a plurality of grooves are continuously arranged, the front and back of the grooves or space between the grooves are covered by a connecting body (13) provided with a heat insulation wall (20) and an exhaust duct (16), and vulcanizing gas generated by a workpiece (10) in the grooves and the connecting body (13) is sucked through the exhaust duct (16). The amount of intake air in the exhaust duct (16) is reduced in response to the amount of sulfide gas that diffuses into the atmosphere being suppressed, thereby taking into account environmental protection.

Description

technical field [0001] The invention relates to a continuous rubber vulcanization system provided with a plurality of vulcanization furnaces in series. Background technique [0002] Conventionally, if there is nothing between the vulcanization furnaces installed in series (for example, Patent Document 1), vulcanization gas is freely scattered in the air, which may cause environmental pollution and influence on the human body. In addition, for example, objects to be heated (workpieces) such as weather strips for automobiles are air-cooled between vulcanization furnaces, so there is a problem that the vulcanization state deteriorates and the quality of the objects to be heated deteriorates. Furthermore, there is also a problem that dirt called grease scale tends to adhere to the opening of the vulcanization equipment when the high-temperature vulcanization gas is cooled. [0003] Therefore, there is known a configuration in which adjacent vulcanization furnaces are directly i...

AI Technical Summary

Problems solved by technology

[0004] According to this structure, although the sulfide gas does not scatter and the temperature does not drop, there are problems in the following problems: checking the foaming state, slack state, posture, passing position of the object to be heated, and correction of the position or posture , processing when an exception occurs, and other operations cannot be performed

In order to prevent this situation, it is effective to regularly clean the grease dirt M, but it requires cleaning costs

It is also possible to check the degree of accumulation of grease and dirt M inside the pipe 6 and clean it as necessary, but it is not easy to check the inside of the pipe 6 in terms of structure

In addition, it is also possible to set the suction volume assuming that the ventilation area is narrow at the start of the vulcanization equipment operation, but it also becomes expensive due to the increase in the air volume for deodorization.
