UD fabric press laminating Crossply Machine

Crossply Machine is designed for cutting segments from the UD, stacking them in the desired orientation – normally 0/90° – and pressing them together.

1.0°UD: 3-axis center tension unwinding can simultaneously carry 3 rolls of UD material for tension unwinding.

2.90°UD: single axis center unwinding, uses pneumatic clamp for clamping material in conjunction with the servo motor for lateral movement.

Machine Description

1.Crossply Machine is made up of 0°unwinding device, 90°unwinding, width fixed device, pressing and laminating device,and rewinding device, etc. It is used for 2/4/6/8UD fabric pressing and laminating. In this way the reinforcement can be made more efficient, leading to a more lightweight and thinner technical textile.

2.The Crossply Machine is equipped with advanced automation and control systems, allowing for seamless operation and precise control over the production process. Its high-speed capabilities enable rapid production, significantly reducing lead times and increasing overall output. This means that manufacturers can meet demand more effectively and efficiently, ultimately improving their bottom line.

3.the Crossply Machine is designed with user-friendly interfaces and intuitive controls, making it easy to operate and maintain. Its robust construction and durable components ensure long-term reliability and minimal downtime, maximizing productivity and minimizing operational disruptions.

4.the Crossply Machine is also designed with sustainability in mind. It is engineered to optimize energy efficiency and minimize waste, aligning with the growing demand for eco-friendly manufacturing practices.

UHMWPEUD Continuous orthogonal vulcanization process:

Put the unidirectional PEUD on the 0° and 90° tension unwinding devices. The 0° UD tension fabric is unwind to the hot pressing platform by the servo traction device before coiling. After the 90° UD fabric is pulled and positioned by the servo width setting device, it is cut by the hot cutting device. The upper hot pressing plane is quickly pressed down, and the pressure is transmitted through signal sensing to drive the composite. Then, the servo traction is used in conjunction with the tension shaft to roll the PEUD orthogonal finished fabric.

Machine Features

The 6000KN four cylinder hydraulic power acts on the 1700 * 1700mm lamination tabletop, combined with HMI+PLC to control pressure, acceleration, pressure holding and other functions.
The 90° UD tension reel adopts pneumatic clamping material combined with servo motor for lateral movement, ensuring that the UD material does not deform or deviate during the movement process; Using servo motor drive for lateral material pulling, the fragment size can be directly inputted and set on the touch screen.
The heat source medium required for the lamination tabletop is thermal oil, equipped with a dual external circulating mold oil heater.
The movable and fixed pressure plates are equipped with pneumatic clamping devices, which are stable and fast;
The laminated product is pulled by servo rollers to achieve longitudinal specification improvement each time, and combined with tension coiling to achieve UD composite product winding.
Adopts thermal cutter for UD fabric cutting, to ensure precise transverse cutting.
The control mode of the AC motor is circuit breaker+contactor+thermal protector+motor
All outputs of PLC are controlled by intermediate relays to execute components;
