Description

Technical Field

[0001] The utility model relates to the technical field of can production, in particular to a centralized oil mist collection system. Background Art

[0002] In the production of cans, a large amount of stretching oil is used when the can body is stretched in the stretching machine to reduce friction and resistance during the stretching process. During the stretching process, the stretching oil is heated and atomized to produce a large amount of oil mist, oil smoke and suspended particles, which pollute the processing workshop, affect the health of the operators, and even cause safety accidents. In view of this situation, most factories currently use one stretching machine with one oil mist collector. This configuration mode occupies a large amount of space and has high equipment costs.

This is not friendly to the atmospheric environment and will also increase the production costs of enterprises. Utility Model Content

[0025] In this embodiment, the other end of each connecting pipe 4 is connected to the oil mist suction port of a stretching machine 5 through an air volume regulating valve 13. Through the air volume regulating valve, the suction air volume of the oil mist collection device for each stretching machine can be adjusted individually.
