I. Machine Dimensions and Weight: Single unit weighs approximately 11 kg, dimensions 350x168x350 mm. II. Applicable Labels: Single-row label rolls with inner diameter 35-75 mm, outer diameter ≤200 mm, width ≤30 mm. III. Machine Power Voltage: Standard is AC 220V; 110V models available upon request. IV. Front Blank Label Strip Length: Approximately 150mm required. This allows the first 150mm of backing paper per roll to remain blank, preventing label waste. (Leaving no blank space is acceptable and does not affect operation.) 5. Why is the label roll core diameter 75mm? If the core diameter is too small, labels wound tightly around it may become curved (arched) after prolonged compression. Curved labels adhere less effectively than straight ones. 6. Label application speed: Adjustable. VII. Setting label application length: Adjust the speed controller, modify the F value in the microcontroller, or use the dimension adjustment knob (though adjusting this knob is not recommended unless necessary). These methods can regulate label dimensions. VIII. What controls this equipment: A microcomputer controller (control center, microcontroller). IX. What material is the machine body made of: Steel plate and stainless steel, with surface treatment applied.
