Flute diaphragm line forming device and diaphragm pasting method thereof

The invention provides a flute diaphragm line forming device and a film pasting method thereof. The flute diaphragm line forming device comprises a line forming mold. The grain forming mold is provided with a specific grain forming structure, and the grain forming structure is used for enabling the membrane to form specific wrinkled cross grains when the membrane is pressed and pasted; in the application, the flute film is pasted through the grain forming mold and the film pasting method thereof, flute film grains which are fine, uniform, regular in shape and digitized can be formed on the pasted flute film, and the flute quality is good and stable; meanwhile, by means of the device and method, flute diaphragm line forming and pasting operation is easy and convenient, the success rate is high, the diaphragm pasting quality is stable, the flute diaphragm line forming and pasting efficiency and quality are greatly improved, and meanwhile the situation that diaphragm waste is caused due to the fact that the succ
