Domestic computerized flat knitting machine operation and maintenance methods

1. Operation precautions:

1) Reading the disk, if it is not smooth, you can turn off the power again and plug and unplug. USB port, if you use Huaxiang controller, you can switch the storage and reading media (U disk and disk) first and then turn on the computer to read the disk.

2) When threading yarn, adjust the antenna elasticity and side antenna tension.

3) Adjust the pattern according to the proofing requirements. Pull force etc.

4) Determine the pattern unfolding and yarn feeder position. The National Flower series also has pre-production capacity.

5) Hang the cloth (not used on the bottom plate machine), lock the line (repeat on the Feihu machine) and immediately give the auxiliary roller closing status. The machine head speed should be less than 0.40m/s, and the cloth piece reaches Release the row lock when the main roller is turned (click the Feihu machine handle repeatedly). Increase speed, pull force, etc.

2. Start knitting

1) Check the density of the fabric pieces and confirm the condition of thick and thin yarns at any time, so as to control the length of the pieces at any time. Follow sample size.

2) Pay attention to the waxing condition of wool yarn and the discharge position of wool yarn. When disassembling the yarn, re-test the mesh and tension.

3) Keep informed of yarn usage, wool color difference, etc.

4) The shirt pieces are divided into codes, and the colors are neatly folded and bundled for delivery.

5) Pay attention to the rewinding cloth and sub-roller yarn (especially the national flower series)

3. How to deal with common problems

(1) Item

1) The mesh becomes larger and larger when knitting

A. Check whether the circuit is in poor contact.

B. Check whether the motor screws are loose.

2) Knitting is performed on both ends at the same time. If the stitch size of one stitch becomes abnormally small, you can consider appropriately increasing the stitch origin point.

(2) Bump the connecting pins (the National Flower series is called long pins)

1) Check whether the mesh is flexible.

2) Check whether the connecting pins run smoothly on the needle bed and whether they can spring up freely when pressed by hand.

3) Check whether the screws of the mesh motor are loose. Check whether the turntable is smooth.

4) Check whether the eye sensor is damaged.

5) Check whether the three pins of the pressure needle are in place. The National Flower series depends on the swing of the electromagnet.

6) If the mesh is too tight, it cannot come out of the loop and the connecting pins will be hit.

7) Check whether the needle guide block of the needle transfer triangle is smooth and flexible.

8) Check the bottom plate and whether the slider is in place and flexible.

(3) Random printing (random needle selection)

1) Check whether the random printing on the fabric is regular, for example, which needle selector is the problem.

2) See if it is a stolen selection or a missed selection. Adjust the gap between the needle selector and the needle bed.

3) Adjust needle selection parameters, needle selection origin, and needle selection fine-tuning.

4) Check whether the needle selection stitch is too tight or too loose on the needle bed. Is it smooth?

5) Check the circuit to see if each plug is plugged in properly and see if there is any poor contact.

6) Check whether the main drive belt is too loose.

7) Check whether the needle ruler is too tight or too loose.

8) Replace the needle selection substrate.

9) Re-find the origin, and pay attention to the copper head part of the National Flower series.
