Fault Handling Method Of Jumper In Electronic Keyhole Machine

The round head eye lock, which is suitable for men's suits, suits and windbreaker, has been widely used in modern clothing production.

Generally, there are jumpers in sewing, which are divided into general jumpers, sewing jumpers and round eye jumpers.

First check carefully whether the needle and suture are reasonable, whether the needle is properly installed, whether the thread tension and stitching tension are correct, and whether the needle and the needle are damaged.

The DO*558 series needles should be used for this type of machine. 11#~14# machine needles should be selected for thin materials, and 16# needles should be used for medium thick materials.

Thread should be used for sewing thread.

When the needle is installed and installed, keep the slot of the machine needle (the lead slot) back to the operator, unscrew the needle fixing screw, place the needle in place, and then tighten the screws.

Correctly wear the stitches. The thread sequence is usually worn by bending needles and cushions, and finally sewing machine needles.

The stitch tension should not be tight enough to ensure that the stitches are beautiful.

If the needle is damaged, please replace it in time. The needle tip should be smooth and polished with oil and stone. If the needle is worn badly, it must be replaced in time.

It is not easy to form jumpers when the cotton thread is used to sew thin materials.

First, reduce the running speed of the machine appropriately. Press the READY key on the panel, and when the indicator light on this key goes out, press the SPEED MAX key, the left screen display function number 35, then press the "+" or "-" on the right screen, and the sewing speed can be set in the range of 400~2 200r/min by 100r/min.

This method can not exclude the malfunction, adjust the installation position of the take-up guide, unscrew the screw on the installation platform of the take-up rod guide, move upward the guide rod of the take-up rod, and adjust the rear fastening screw.

On the contrary, when sewing the thick material, the screw can be loosened to improve the reverse line of the sewing material and adjusted downward to move the take-up rod guide.

The gap and synchronous adjustment of the bending needle are not correct.

First check the adjustment gap between adjusting needle and bending needle. When sewing thin material, the smaller the fit gap is, the better.

Adjustment method: unscrewing the fixation pin of the bending needle, adjusting the clearance between the needle and the left bending needle and the right bending needle, and ensuring the clearance between the needle and the needle and the bracket, for example, if the left or right curved needle is an early or late time, the adjustment of the right bending needle is used to solve the problem, adjusting the bending needle driving shaft guide, rising upward, the right bending needle being synchronous and getting earlier, and descending downward, the right curved needle is simultaneously delayed.

The switch time of distributor is not adjusted properly or the action is not smooth.

First, use soft brushes to remove residual debris and other debris around the bending needle. Then, loose the fixed screws of the distributor drive shaft guide, move the guide shaft up and down to move the distributor, so that it does not collide with the needle and the gap between the left and right sides is equal, that is, X1=X2.

Adjust the rear fastening screws.

At the beginning of the sewing, jumper is carefully inspected to clear the bottom line and the core line.

First check the right and left distributor installation position is correct.

The correction method is to move the left distributor, and the gap between the bending needle injury or the foot pin and the needle drop is too large.

Check the repair or replacement of the bending needle, adjust the clearance between the presser head and the needle of the machine needle, unscrewed the fixing screws of the crank seat of the presser foot, move the foot crank to the A direction, and reduce the gap between the presser head and the needle at the needle, then adjust the fastening screws of the foot crank seat after adjusting.

Round head eye

Properly reduce the sewing speed of round head eyes.

According to the READY key on the panel, when the indicator light on this key goes out, then press the "+" or "-" number on the left screen to set the function to 36, then set the speed value according to the "+" or "-" number on the right screen.

The thread of the machine needle line is too large, and the bending needle is not good for drawing the wire ring.

Unscrew the screw, adjust the wire pick up wire upwards, then the needle thread is pulled out smaller, the wire ring is reduced, and the bending needle is easy to hook.

Adjust the screws and tighten them.

There are many jumpers in sewing. It depends on the experience of the mechanic and the actual faults of the machine.
