Description

Technical Field

[0001] The utility model relates to the technical field of fast air extraction devices, in particular to a fast air extraction device for a vacuum vulcanizing machine. Background Art

[0002] The quick air extraction device of the vacuum vulcanizer is a device used to quickly extract the air in the vulcanizer to form a vacuum environment. It is usually composed of a vacuum pump, a valve and a piping system. When using a vacuum vulcanizer for vulcanization, the air in the vulcanizer needs to be extracted to ensure that the sulfide can fully contact the material and improve the vulcanization effect. The traditional air extraction method takes a long time, while the use of a quick air extraction device can greatly shorten the air extraction time and improve the vulcanization efficiency. The quick air extraction device extracts the air in the vulcanizer through a vacuum pump, and controls and guides it through valves and piping systems. When the air extraction device starts working, the vacuum pump will generate negative pressure, extract the air in the vulcanizer into the pump, and form a vacuum environment. Once the air extraction is completed, the valve will close to keep the vacuum environment stable.

[0003] When using some existing quick exhaust devices of vacuum vulcanizers, most of them need to be connected to the vacuum chamber of the vulcanizer through pipelines. However, when connecting some existing pipelines, the connection method is mostly relatively simple, which may cause leakage during use, reducing the efficiency of exhaust. Therefore, it is necessary to solve this problem. Utility Model Content
