AI Technical Summary

Technical Problem

In the prior art, lightweight nonwoven fabrics are easily affected by airflow disturbances, equipment vibrations and other factors on the feeding mechanism, which can lead to trajectory deviation, folding and accumulation, affecting the quality of thermal fusion.

Method used

A negative pressure adsorption feeding mechanism is adopted, which forms a negative pressure area by setting an adsorption component under the conveyor belt. Combined with a uniform air distribution plate and a multi-channel exhaust structure, the stability and flatness of the composite fabric are ensured during the conveying process.

Benefits of technology

It effectively adsorbs the composite fabric, preventing deviation and deformation, improving the stability and flatness of the fabric feeding process, and enhancing the quality of thermal fusion.

Abstract

The application provides a negative pressure adsorption cloth conveying mechanism and a composite cloth hot melting device. The negative pressure adsorption cloth conveying mechanism comprises a rack, a conveying mesh belt, a conveying roller set, a driving piece and an adsorption assembly. The conveying roller set comprises a driving roller and a driven roller. The driving roller and the driven roller are rotatably installed on the rack. The conveying mesh belt is rotatably sleeved on the driving roller and the driven roller. The conveying mesh belt receives the composite cloth to be hot melted. The driving piece is installed on the rack. The driving piece is used for driving the driving roller to rotate, and then drives the conveying mesh belt to rotate through the cooperation of the driven roller. A plurality of air holes are formed in the conveying mesh belt. The adsorption assembly is arranged between the upper side belt body and the lower side belt body of the conveying mesh belt. The adsorption end of the adsorption assembly faces upward. The adsorption assembly sucks the air above the conveying surface of the conveying mesh belt through the air holes, so as to form the negative pressure for adsorbing the composite cloth on the conveying surface of the conveying mesh belt. The composite cloth can be effectively adsorbed on the conveying mesh belt, and the stability in the conveying process is ensured.
