Debugging of Double Circular Knitting Machine

1.Upper dial and lower syringe adjustment

• Loosen lower syringe and lifting ring on machine. Use dial gage to adjust concentricity of syringe to grail. Adjust and lock eccentric positioning wheel. Then, lock the screws.
• Loosen all of connecting screws on feet and pot.
• Put dial gage on the surface of upper dial. Gauge outfit points to external diameter of lower syringe. Adjust regulating screws on the feet to make reading of dial gage less than 0.05mm.
• Lock connecting screws on pot. Reading of dial gage should be kept below 0.05mm.

2.Roughness of upper dial and lower syringe adjustment

• Adjust the gap between upper gear of main transmission and gear on pot.
• Put dial gauge on the lower syringe. Gauge outfit points to the surface of upper dial.
• Start machine and observe reading on dial gauge. If reading is higher than 0.05mm, loosen connecting screws on pot. Turn 6 crack screws and put gasket under screws. Lock connecting screws.

3.Needles adjustment

• Adjust four regulating screws on the gear of main transmission. Rotate gear on pot to an angle. Adjust upper dial and lower syringe to required position.

4. The height of upper dial adjustment

• Loosen three fastening screws on upper dial. Rotate gear. Then dial will rise. Lock fastening screws after adjustment. Note: Dial cannot fall too low which may caused damage to needle. Before lowing dial, the height should be low than required height. Then push the dial back to required height in case of damage caused by falling needle when machine starting.

5. Time difference of triangle adjustment

• Loosen three fastening screws on upper dial. Adjust two screws on the permanent seat of triangle. Then triangle on upper dial will rotate. Lock three fastening screws after adjusting.

6. Triangle adjustment

• Uniform tension improves the quality of textile. Resetting the position of needles can acquire uniform tension.
• Use tensioner to measure tension on every yarn.
• Use hexagon spanner to turn calibrator on triangle
• Inspect and adjust the tension on every yarn.

7. Needle point adjustment

• Loosen connecting screws on triangle and lifting ring. Rotate crack screw to raise the whole lifting ring. Put equal gasket under every connecting screws. Then the needle point will rise.
