What to do if the high-speed knitting machine knits quality products? Xuzhou Qixing Machinery Co., Ltd. will introduce it below.
Problem: Yarn skipping occurs during knitting.
Causes:
- The wire strands of the high-speed braiding machine are broken, resulting in uneven control of the tension on the changing track, accumulation of wires in the take-up, and uneven crossing of the changing lanes.
- The motor rotor tension is not adjusted evenly, and the thread strands are not tight enough.
Prevention methods:
- Adjust—down to change track tension.
- Adjust—lower motor rotor tension.
Problem: The knitting surface is rough.
Causes:
- When the copper wire is connected to the strand or ground terminal, the interface is not neatly repaired.
- The take-up tension was too high and a single thread in one strand was torn off.
Prevention methods:
- When connecting the copper wires, repair the interface neatly. Press the starting point of the braiding machine flat towards the direction of the wire collection. The grounding wire cannot be twisted and can only be welded.
- Moderately reduce the take-up tension without deviating from the traction belt.
Causes:
- Because the relative density of weaving is related to the number of weaving spindles, the number of each spindle, the outer diameter, pitch, and the writing angle.
- The number of spindles, the number of spindles, and the hole diameter will not change. The more pitch braiding angles, the smaller the relative braiding density.
Prevention methods:
- Check the weaving pitch and weaving angle, correct any problems in time, and check whether there are any missing roots, missing strands, and small holes, which need to be filled and replaced in time.
- Keep the number of spindles, quantity, hole diameter, weaving pitch, and editing angle in harmony with each other.
Problem: The relative density of the braid layer is uneven and the strands have different tightness.
Causes:
- The strand tension of the knitting machine is out of control.
- If the die selection is too large, the cable core will shake to a certain extent during weaving.
Prevention methods:
- Replace the torsion spring that has lost elasticity due to long-term use and adjust the tension of each strand.
- Choose the appropriate mouth mold.
Problem: uneven knitting pitch
Causes: The number of turns of the cable on the traction wheel is too small, causing the rolling motor rotor speed ratio and the traction line speed to be unstable.
Prevention methods: Appropriately adjust the number of turns of the high-speed knitting machine cable on the traction wheel, and adjust the speed between the two to be stable.
