Quilting machine failure and troubleshooting.

1. No line at quilting machine?

First, check to see if the needle is too deep.

Second, whether the shuttle has been used for long needs to be replaced.

Third, the ratio of the shuttlecock to the needle is not adjusted well.

2. The computer quilting machine does not lift the needle, and the sensor is changed, but it is still not good to use.

How to do?

First, check whether the sensing line is short-circuited.

Second, check whether the data line of the functional board is short-circuited (inside the host).

Third, check whether the functional board is loose, remove the functional board, use the eraser to clean, and then install.

Fourth, change the host or make technical personnel telephone.

3. Cant boot?

Open the side cover of the main box, and find the memory strip (strip board) to remove the memory strip and reinstall it into the slot, connect the power supply, and turn on the machine.

The indicator light is not on, check whether the power supply is energized.

Check the indicator light and check the display power.

Still can not open the machine, the possible failure is the main board transportation damaged, memory burning or power problems.

4. The host installation will not work?

Enter the computer into the operation screen and see the F5 test. In the case of machine power, click the "up and down" arrow on the keyboard to observe whether the machine is moving in accordance with each other.

If not, adjust on the drive.

After the machine has been installed, it may not be possible to operate the function board in the main engine, please remove and reinstall it.

Check whether the plugs are correct.

If the machine is not running in one direction, consider the drive damage in this direction.

5. Quilted pattern distortion?

Check the belt slack and consider a drive in one direction damaged.

Pattern reselection.

6. Machine noise problem?

First, the gap adjustment of nylon gear on the connecting shaft of the machine head of quilting machine.

Second, the bearing adjustment on the upper and lower transmission shaft.

Third, belt loose.

Fourth, the pulley screw loose.

7. Pattern movement?

The reason:

There are problems in pattern making.

2. The machine frame runway has the card point and oil.

3. Synchronous belt damage and drive failure.

4. Damage to main controller.

5. Wrong signal for the drive.

6. The stepping signal line is interrupted by interference.

Methods:

One, make the pattern again.

2. Replace the bearing of the frame track and maintain the oil.

Replace the synchronous belt.

Iv. Replace the drive.

5. Replace the main controller.

6. Re-check the signal wire connection and check the line to eliminate the interference source.

8. The machine frame does not move?

Cause: drive failure, drive signal line break, main controller damage, step motor damage.

Methods: replace the drive, replace the signal wire, replace the main controller, and replace the stepping motor.

Check the broken line?

1. Whether there are burrs in the needle holes.

2. Is there any burr in the tip of the hook?

Is there any burr in the shuttle skin?

The needle is bent.

5. Whether the pick of wire spring is too large.

6. Is there any burr in the hook?

7. Use of substandard shuttles.

8. Unqualified suture is used.

10. How to check the broken needle?

1. The needle and hook tip are too small to be touched.

2. The needle is too thin.

The quilt is too thick.

3. The foot height is too low, so that the needle and foot rub.

11. How to check the jumper?

The reason:

One, the machine needle gap and the hook line tip position is too large.

Its too early to write.

3. High pressure feet.

4. The needle plate hole is too large.

Methods:

1. The position of the machine needle gap and the tip of the hook line is 0~0.1mm.

2. The needle should rise from the lowest point to 2.5~3mm, and the tip of the hook line should be higher than 0.5~1mm.

3. The height of the pressure foot should be higher than 0.5mm of the seam thickness.

Iv. Replace the needle plate.

12. How can the computer quilter and needle adjust?

In the nose and frame synchronization and other normal cases, put a needle into the lowest, and then put the hook pointed toward the top of the needle dents, and then the needle lift up 2 ~ 3 mm, the hook screw, is ok.

13. After the computer quilting machine has gone through the outer circle, it is not working in the inner circle.

Reason: the stepping motor has a tight tooth.

Method: to loosen the belt of the stepping motor.

14. After finishing a quilt, the computer quilting machine will not reach the end of a dozen centimeters.

Reason: loose, synchronous belt loose.

Method: tighten the synchronous belt.
