UHMWPE UD continuous orthogonal vulcanization Crossply Machine

Crossply Machine working process:

1. Feeding the unidirectional PE UD on the 0° and 90° tension unwinding devices.

2. The 0° UD fabric is feeding with tension to the hot pressing platform by the servo traction device.

3. After the 90° UD fabric is pulled and reach the servo width setting position, it is cut by the hot cutting device.

4. The upper hot pressing head is quickly pressed down, and the pressure is transmitted through signal sensing to drive the composite.

5. The servo traction is used in conjunction with the tension shaft to roll the PEUD orthogonal finished fabric.

Machine Description

Crossply Machine is cutting segments from the UD, stacking them in the desired orientation – normally 0/90° – and pressing them together. It 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. the Crossply Machine represents a significant leap forward in manufacturing technology, offering unmatched performance, versatility, and sustainability. With its advanced features and innovative design, it is poised to become the go-to solution for manufacturers looking to elevate their production capabilities and stay ahead of the competition. Experience the future of manufacturing with the Crossply Machine.

Main 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.
0° UD 3-axis tension reel, capable of carrying 3 rolls of UD material for tension unwinding;
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 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.
By relying on the pneumatic structure of the multi-point upper pressure plate, the material clamping force points are kept consistent for rapid descent;
Utilize thermal knife body to perform transverse fragmentation;
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.
High frequency quenching and hard chromium plating treatment are carried out on the surface of the moving track to ensure a high interest rate of service life.
