mechanical belly

[keannu]

I can assume this "mechanical belly" is something big and the central part of the working procedures, but not sure of it. Is it a metaphorical meaning?

ex)The "mechanical" quality of life that industrialization promoted was proving to be a source of dissatisfaction for many, which made it ripe for its satirization by Charlie Chaplin in his 1936 film Modern Times.....In the film's most famous scene, he becomes so overwhelmed by his work that he simply lies down on the conveyor belt and allows himself to be pulled into the factory's mechanical belly.
