Is there anything to do with the wire clamp when the bottom line of the computer board flat car is m

The bottom line of the computer version of the flat car is messy and has nothing to do with the wire clamp.

It may be due to the fact that the manufacturer did not fix the wire firmly during assembly.

In this case, it does have a certain relationship with the wire clamp. However, it may also be caused by the fact that the wiring was not re-fixed at the time of wiring or after repairs.

Pulling the bottom plate into a mess, of course it doesn't matter if Lu Jia is discouraged, if it is, she will definitely cause a short circuit.

The computer version of the flat car bottom line is messy and has a relationship with the good air intake, and the shop owner has a relationship with fake gasoline.

In this case, there should be no problem at all, and it should have nothing to do with the clamping line of the chassis, and there is no relationship between the two.

The owner of the shop, the bottom line of the flat car is messed up into a code yoga liner.

The bottom line of the computer flat car is messy and has nothing to do with the wire clamp.

These two are actually unrelated, we know that they only need to be normal.

It doesn't matter what the tablet is messed up with, it's a normal circuit.

The flatbed you are talking about, its illusion is actually related.

Normal, this is static electricity, especially the stainless steel panel, but the voltage tester can not be measured, generally with the back of the hand to touch the feeling of electricity, with the hand contact is not felt, if the hand also has a feeling, that is leakage.

If it's a silk ray, it's normal, the thread itself is very smooth, and if the wire clamp is too tight, the thread will be squeezed out. The solution is also very simple, either loosen the wire clamp, or find a way to make the wire from the spool to the wire clamp inlet have a little tension, that is, the tight point.

2. Start with the simplest and see if the pressure of the small wire clamp is too high. The small wire clamp is used to control the length of the thread. If the pressure is too high, then the thread end is too short and the thread end will come out of the pinhole the second time you sew.

3.When the tangential solenoid is working, you see if the large wire clamp pops open. If it doesn't pop off, push the large wire clamp a little less inward.

4.Whether the tangent cam is in the correct position. This is very likely. I won't say much about that.

5.Whether the handwheel is installed correctly, whether the sensor at the handwheel is installed correctly or there is a problem.

6.If the imitation brother is a computer flat car. Such as standard. You see if the moving knife is installed too far in front of it. That is, the tangent is too early.

7.If it is a machine that imitates a heavy machine, whether the installation position of the fixed knife is on the far left.

8.The low line is whether the pressure of the line stopper is too high.

9。If it is a standard computer flat car (imitation brother), pay attention to whether the left side of the moving knife is worn. The standard computer flat car is prone to tangent precession and the knife does not reset.

If the knife is stuck, the needle will collide with the knife when the needle is lifted for the second time, which will damage the left side of the needle and the knife (you can remove the brother's knife and pay attention to the design and shape of the knife, you will understand). When there is a scar on the left side of the knife. When tangential line, the upper line will not smoothly enter the notch of the moving knife, resulting in the upper line being too short.

The second time you start the needle, the thread will fall off from the eye of the needle!

10.Whether the reel and the wire crosser are perpendicular to the upper, if the angle of the reel and the crosser is too different, the resistance to the upline will be too large. When causing tangents, the thread end is too short! )

This is usually common, the wire clamp is broken, and you can replace it with one.

What brand, what model, and how many years has it been used. If there is any abnormal sound in the fuselage, first reduce the pressure of the presser foot on the sewing material to see.

This is usually common, the wire clamp is broken, and you can replace it with one.

This is because if you adjust the clamping force too small, the maximum value is 8, if you make this mistake at 1 or 2, you can restore the original factory settings if you don't adjust it.

We can't complain, and we can't sigh every day.

The wire clamp is to adjust the tightness of the line by the pressure of a spring, if the line can not be clamped, it may be that the spring has no tension, and you can change it.

Here's how:

1.You can check the position of the loose wire ejector pin on the loose wire ejector rod. The sewing machine is sewing at the highest speed, the end face of the loose thread ejector rod pin falls on the plane of the loose thread ejector rod, and the thread clamp works.

In the low-speed sewing state, the end face of the loose thread ejector rod pin still falls on the plane of the loose thread ejector rod, but it is close to the inclined plane of the loose thread ejector rod. In the state of trimming and parking, the end face of the loose wire ejector pin falls on the plane of the loose wire ejector rod, and the wire clamp floats and does not work.

2.After the first two inspections are in place, if the problem is still not solved, it is likely that the loose wire ejector pin is short. You can remove the original loose thread ejector pin of the sewing machine, make an extended loose thread ejector pin, and then reinstall it.

This kind of fault generally do not change the bobbin shell, do not easily change the needle, need to be checked, if loose or misaligned, etc., to correct.

Pay attention when checking the computer flat car:

1) The winding amount of the bobbin should not exceed 85% of the outer diameter of the bobbin.

2) Replace the bobbin with an aluminum bobbin, because the light weight of the aluminum bobbin can reduce the inertia of the bobbin movement.

3) Choose a hook with anti-aircraft reeds.

4) Or put a piece of flannel cloth at the bottom of the ordinary hook bobbin to increase the friction resistance of the bobbin.

5) Reverse the bobbin so that the direction of rotation of the bobbin is opposite to the direction of the movement inertia of the bobbin.

6) The gap between the bobbin core and the bobbin shell should be as small as possible.

7) Reduce the sewing speed when using, especially when the thread is cut and stopped.

8) When trimming the thread, the bobbin ejector rod should be pressed to check whether the bobbin pressure rod works.
