A semi-automatic adhesive machine of a certain type can handle cardboard from 400mm x 400mm to 1200mm x 200mm through adjustable crease correction device.
Stainless steel wheel glue coating technology is adopted to control the glue amount error within ±0.1g/m2 to prevent the plastic from spilling over and deforming the cardboard.
Drying efficiency: With a hot air circulation system, the glue can solidify initially in 3-5 seconds, reducing the risk of adhesion during stacking.
2. Alien Boxes and colour boxes: the Advantagess of Multi-functional Equipment
For products that require two pieces of adhesive to be formed into a box, cartridge or special shaped structure, it is recommended to select devices that have the following functions:
Local spray: through the nozzle to achieve a special shape of the box precision coating, glue coverage rate of up to 98%.
Abrasive pre-treatment: Coarse processing of the adhesive to enhance the adhesion of the adhesive, so as to increase the peel strength by 30%.
Multi-material compatibility: supports mixed production of A/B/C flute corrugated cardboard with thickness between 2 and 8mm.
III. In-depth analysis of Technical Parameters
1. Core Performance Indicators

Speed of operation: It is recommended to select equipment operating continuously at a rate of not less than 80 metres per minute to meet the requirements of mass production.
Stability: The equipment shall pass a 24-hour continuous operation test with an average failure interval of more than 2,000 hours.
2. Electricity and Energy Consumption
Power supply Configuration: Mainstream uses a 380V three-phase power supply with a power range of 5-15kW.
Energy-saving design: Preference is given to equipment equipped with frequency conversion speed control system, which can reduce energy consumption by 20% to 30%.
Air pressure requirements: Some devices require compressed air systems with a pressure of between 0.6 and 0.8MPa to drive pneumatic components.
3. Intelligent Functions
Data monitoring: real-time acquisition of production data (e.g. speed, temperature, glue amount, etc.) through sensors and touch screens.
Fault warning: When equipment malfunctions, the system automatically alerts and records a code for the malfunction to quick troubleshooting.
Remote maintenance: supports remote diagnostics and software upgrades the Internet to reduce downtime.
IV. INTRODUCTION Environmental and Sustainability Considerations
