4) It has a segmented pressurization function. According to the process needs, the number of pressurization times, lamination pressure, and interval time of the upper chamber can be set;

5) The conveying system adopts a chain transmission structure and can realize continuous loading and unloading, improving equipment utilization.

6) SIEMENS programmable controller can realize communication with HMI and meet the requirements of modern industrial automation control.

7) The inlet and outlet tables are equipped with independent control buttons to facilitate material loading and unloading; the loading table is equipped with a segmented advance control form, and a certain step forward distance can be set according to actual needs. That is, each time the button is pressed, the material The table automatically advances a certain distance to facilitate loading.

8) The operating platform adopts a 10-inch high-quality touch screen with a simple interface, high sensitivity, easy operation, and easy learning. During operation, the main operating processes are prompted in real time through sound and light; the process parameters are simple to set, and multiple process parameters are displayed in the same window, which is convenient. Monitor and store a variety of process recipes for selection in production.

9) The process parameters are automatically memorized and will not be lost or reset after restarting. The system automatically records the main operating steps and provides data for component quality analysis. It has a lamination number statistics function to facilitate checking the number of shifts and component output. It can also be used as a reference for equipment repair, maintenance, and replacement rate cycles of wearing components.

1. Cleaning system
2. General configuration:

1) The laminator is equipped with brush rollers for both upper and lower circulation, which can effectively remove EVA residue;

2) Garbage boxes are installed on the upper and lower circulation rollers of the laminator to keep EVA, dust particles, and other debris clean and easy to clean;

2. The following are additional configuration plans:

The upper and lower circulation of the laminator is equipped with an efficient cleaning system. This system adopts the Komax design solution. After verification by customers, it is by far the most effective solution among high-temperature cloth cleaning systems for laminators. Received unanimous praise from customers:

1) The high-temperature cloth has a good cleaning effect, avoiding manual cleaning, making the equipment close to unattended status, saving workforce, effectively extending UPTIME, and improving equipment production efficiency.

2) The dirt collection system is equipped with industrial vacuum equipment to effectively collect EVA, dust particles, and other debris, keep the equipment clean, reduce personnel downtime for cleaning TIME, and effectively avoid secondary contamination of the component backplane.

1. security measures
