INVT DA200A Servo for Die-cutting Machine Application

Introduction of die-cutting machine

Die-cutting machine is an important post-press packaging processing equipment, which uses steel knives, metal molds, steel wires (or steel plate carved into templates) to exert a certain pressure through the embossing plate to roll and cut the printed product or cardboard into a certain shape.
This kind of machine is mainly used for die-cutting (full breaking, half-breaking), creasing and hot stamping operations for non-metallic materials, self-adhesives, EVA, double-sided tape, etc., as well as laminating and automatic waste discharge.

Traditional control schemes

1. The traditional die-cutting process is controlled by asynchronous motor, which has high energy consumption and long installation time.

2. The pulling part adopts ordinary servo control, and the positioning accuracy is poor, and it is generally controlled at ± 10 wires.

INVT Solution

According to the needs of customers, combined with the pain points of traditional solutions, INVT provides customers with DA200A series AC servo drive solutions.

In this scheme, INVT servo motor replaces the traditional ordinary motor, the speed is faster, the start and stop is more stable, the pulling shaft adopts INVT DA200A servo, the speed loop response frequency is 2.5kHz, high dynamic response, the setting time is shortened, and the high-end mechanical performance is maximized, and the 23-bit high-precision encoder makes the positioning more accurate.

Customer value

1. Accuracy improvement: The processing accuracy of the product can reach ±5 wires, which is greatly improved by 100% compared with the traditional solution.

2. Production speed increase: from the original 200 pieces/min to 300 pieces/min, the speed is increased by 50%.

3. Easy installation: It takes 6 hours for a skilled worker to install the spindle in the traditional scheme, and only 3.5 hours in the new scheme, and the efficiency is increased by 70%.

4. Easy maintenance: the spindle transmission structure is simplified, the after-sales maintenance is simple, and the energy saving is 20%.
