AI Technical Summary

Technical Problem

In existing nonwoven fabric coating machines, the synchronization between the electrostatic bar and the pressure roller is poor. Due to the delay in electrical signal transmission and electromagnetic interference, the bonding effect of the molten material during the composite process is not good.

Method used

By setting up a lifting mechanism and a valve opening mechanism, the mechanical linkage control between the electrostatic roller and the pressure roller sleeve is realized, ensuring that the lifting of the electrostatic roller and the expansion of the pressure roller sleeve are synchronized. A single power source drives multiple working rollers, and contact control is used to open and close the air circuit, reducing the impact of electromagnetic interference.

Benefits of technology

It improves the uniformity of molten material bonding on nonwoven fabric, reduces equipment costs and failure rate, ensures coating quality and tension stability, and avoids stretching or uneven coating problems caused by asynchronous speed.

Abstract

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.
