This invention discloses a nonwoven fabric coating machine, belonging to the technical field of coating machines, including a base. This invention achieves mechanical linkage control of the expansion and tightening actions of the electrostatic roller and the pressure roller sleeve by setting up a lifting mechanism and a valve opening mechanism. When the cam rotates with the transmission mechanism, the cam pushes the lifting wheel downwards, causing the mounting frame and the electrostatic roller to descend as a whole, bringing the electrostatic roller close to the surface of the nonwoven fabric to apply electrostatic charge. Simultaneously, the contact point at the top of the cam is lifted and lowered during rotation, causing the block to move downwards in the connecting groove, thereby opening the air passage between the air inlet pipe and the air outlet groove. This allows compressed air to enter the cavity of the pressure roller sleeve through the connecting channel, causing the pressure roller sleeve to expand. This structure avoids problems such as electrical signal transmission delay and electromagnetic interference, ensuring that the lifting and lowering of the electrostatic roller and the expansion of the pressure roller sleeve are synchronized, allowing the molten material to achieve a more uniform and robust composite under the dual effects of electrostatic adsorption and roller pressure expansion.
