4 Head Uv Roll To Roll Printer

1. Maintain a stable nozzle inlet pressure (±0.5 kPa) through a gear pump or diaphragm pump to avoid ink breakage or ink flying. Dynamically adjust the ink supply according to the printing speed.

1. Control printer start/pause/emergency stop (response time <0.1 seconds), support safety interlock (for example, prohibit printing when the door is not closed).

1. Two independently adjustable pressure rollers (pressure range 5~50N adjustable) can apply differential pressure to different materials (such as PET film/canvas) to eliminate wrinkles caused by uneven thickness of the material.

1. Real-time encoder feedback (resolution ≥ 17 bits) achieves a coil stepping accuracy of ±0.01mm, avoiding the step loss problem of traditional stepper motors.

1. The straightness of the C-level guide rail reaches ±0.003mm/300mm, ensuring that the nozzle moves without jitter (suitable for 1200dpi high-precision printing). ±0.002mm, meeting the strict registration requirements of variable data printing.

1. Servo motor + tension sensor closed-loop control (error <±0.5N) to avoid material stretching deformation.

2. Adapt to the elastic differences of different materials (such as PET/PP/cloth) to prevent wrinkles or breaks (speed range 20~80m/min).
