AI Technical Summary

Technical Problem

In existing technologies, the amount of adhesive inside the liquid storage box decreases due to prolonged use, and staff cannot detect and replenish it in time. This results in insufficient adhesive adhering when the fabric is passed through, affecting the composite molding efficiency of multi-layer nonwoven fabrics.

Method used

A multi-layer composite nonwoven fabric forming device was designed, which uses a sealing plate and airbag system in the liquid storage frame. The automatic addition of glue is controlled by the pressure of the airbag to ensure that the fabric is coated with sufficient glue when it is passed through. The device includes the coordinated use of components such as support frame, liquid storage frame, guide roller, sealing plate and sliding assembly.

Benefits of technology

Automatic glue replenishment is achieved, ensuring that sufficient glue adheres to the fabric as it passes through the liquid storage frame, thereby improving the efficiency and quality of multi-layer nonwoven fabric composite molding.
