Die-cutting machines have high requirements for speed and precision in production. This artile briefly introduces FRECON Servo system SD300P series and SD100P series in Y-axis asynchronous die-cutting machines.
Die-cutting machines are primarily used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, and cell phone adhesive pads. Using steel blades, metal molds, and steel wire, the die-cutting machine applies pressure through a stamping plate to cut printed products or cardboard into defined shapes. It is a crucial piece of equipment for post-print packaging processing. The image below shows a Y-axis asynchronous die-cutting machine.
The die-cutting process is the most commonly used process for packaging printed materials. It is a forming process in which a die-cutting knife is used to combine a die-cutting plate according to the pattern required by the product design, and under the action of pressure, the printed material or other coiled blanks are rolled into the desired shape or cut. The creasing process uses a creasing knife or creasing die to press out line marks on the sheet material through the action of pressure, or uses a rolling wheel to bend the sheet into a predetermined position. Usually, the die-cutting and creasing process combines the die-cutting knife and creasing knife in the same template, and performs die-cutting and creasing simultaneously on the die-cutting machine, which is simply called die-cutting. The main process of die-cutting and creasing is: plate loading → adjusting pressure → determining the rules → pasting the base material and auxiliary materials → trial die-cutting → formal die-cutting and creasing → waste removal → finished product winding or cutting into sheets → counting and packaging.
1. Traditional die-cutting processes use asynchronous motors, resulting in high energy consumption and a lengthy installation process.
2. The material drawing process uses conventional servo control, resulting in poor positioning accuracy, typically within ±10 degrees.
Taking a Y-axis asynchronous die-cutting machine as an example, FRECON provided the SD300P and SD100P series drive solutions based on customer needs and addressing the shortcomings of traditional control solutions.
In this solution, FRECON servo motors replace conventional motors with 23-bit encoders. The die-cutting and feed axes utilize the SD300P general-purpose servo drive, which has a 3kHz speed loop response bandwidth. The asynchronous feed axis utilizes the SD100P economical servo drive for low-power motors, which has a 2kHz speed loop response bandwidth and features vibration suppression, significantly improving system responsiveness.
After using this control solution, the product processing accuracy can reach ±5 threads, a significant improvement of 100% compared with the traditional solution; the production efficiency has increased from the original 200 pieces/minute to 300 pieces/minute, a speed increase of 50%; the mechanical noise is small; the spindle transmission structure is simplified, and after-sales maintenance is simple.
