Description

Technical Field

[0001] This utility model relates to the technical field of fabric production, and in particular to a multi-layer bonding and pressing device for composite fabrics. Background Technology

[0002] A laminating machine for composite fabric processing is a type of equipment used to manufacture composite fabrics. It can bond different materials together to create composite fabrics with multiple functions and properties. This equipment uses high temperature or pressure methods to tightly bond the materials together.

[0003] Existing composite fabric multi-layer lamination and pressing devices, such as the composite fabric processing lamination machine disclosed in utility model patent application number 202420141168.3, mainly include a fixed plate, a support plate 1 fixedly connected to the top surface of the fixed plate, an mounting block fixedly connected to the side of the support plate 1, a drive motor mounted on the mounting block, a transmission shaft 1 fixedly connected to the output end of the drive motor, and a conveying roller 1 mounted on the outer surface of the transmission shaft 1. The support plate 1 has two sets symmetrically arranged. In use, the drive motor is started, and the output end of the drive motor drives the transmission shaft 1 to rotate. When the transmission shaft 1 rotates, it drives the conveying roller 1 to rotate. When the conveying roller 1 rotates, it drives the composite fabric body between the conveying roller 1 and the conveying roller 2 to move. When the composite fabric body moves, it drives the conveying roller 2 to rotate, thereby flattening and positioning the composite fabric body. When the transmission shaft 1 rotates, it drives the disc to rotate. When the disc rotates, it drives one end of the connecting rod to move around the transmission shaft 1 in a circular motion, causing the transmission shaft 2 to slide in the slide rail, thereby driving the pressure roller to roll and press the laminated composite fabric.

[0004] However, with existing pressing devices, the adhesive is mostly not yet solidified when pressing, and pressing immediately can easily affect the bonding effect. Moreover, the pressing process can easily cause the fabric to be pulled, thus affecting the fabric's performance. Utility Model Content
