Introduction of solvent-free compound machine
Solvent-free laminating machine is a device that uses solvent-free adhesive to compound two or more substrates. It originated from the European process and has the characteristics of safety, environmental protection, hygiene, high efficiency and energy saving. Therefore, this equipment is suitable for It has a wide range, especially in the field of food and pharmaceutical packaging.
In a packaging machinery and equipment company in Jiangsu, the customer’s solvent-free laminating machine is a two-layer lamination, single-station winding and unwinding structure. The following requirements are put forward for the control system of the equipment:
- Constant tension control
- High control precision
- High response speed
- Improve overall efficiency
- Save cabinet space

value of customer
01Energy saving up to 20%
The internal flow of energy is realized through the common DC bus scheme, which saves more than 20% energy compared with the conventional scheme.
02The overall efficiency is increased by 30%
Using EtherCAT high-speed industrial bus communication, it perfectly realizes the stable output of tension and speed, and can be adjusted in real time, which increases the speed of winding and unwinding by 30%.
03Save 40% of cabinet space
Goodrive600 series inverters are installed close to each other, saving 40% of the cabinet space compared to conventional inverters.
04 Stable and precise
- The winding tension is stable, and the winding material does not deviate.
- The overall line speed is stable and will not cause material loosening or stretching.
- The target value of unwinding tension can be changed in real time according to the change of roll diameter.
- The traction roller can adjust the feeding speed and frequency in real time, and the material will not stretch or loosen.
