Why does computer quilting machine always break when quilting quilt?
Rotating spindle and needle timing adjustment: turn the handwheel to make the needle B at the bottom point, then the machine needle B up 2.2-2.5 mm. At this time, the hook D on the rotary spindle intersects with the notch of the needle on the right side of the machine needle, and the contact point shall be E1-1.2 mm higher than the center of the needle hole of the machine. Because the above specific dimensions are visual, the operator must be careful and accurate.
Traces of various shapes, the normal traces should be A, if the line is not normal, there will be cracks, irregularities and broken lines and so on.B noodles too tight, too loose bottom line, should relax the surface line. Tighten the reed screw on the shuttle sleeve. C is the face line is too loose, the bottom line should be adjusted too tight, in contrast with B method.D E, the line mark is the base and the surface caused by loose and tight line at the same time, can refer to the above method of repeated adjustment.
Synchronous adjustment needle and hook: remove the head guard plate A, sewing head rotation wheel, needle bar down to the lowest point, unscrew the fastening screw rod B, move up and down the needle bar, make the needle pinhole center D and spin Suoneikong garden weekly E homogeneous phase, and then the needle B rod screws tightened, and should pay attention to the correct position of the long needle groove, and needle bar in the point position, the lower end of the rod machine has two lines, the relative position of the two line and the head shell as auxiliary mark adjustment. After the machine needle is installed, the synchronous adjustment of the machine needle and the rotary shuttle is carried out: whether the matching between the rotating shuttle and the needle is accurate is the cause that can directly influence the normal sewing of the machine. Therefore, the operator must adjust very accurately.
Several methods for adjusting the head of computerized quilting:1, installation machine needle: choose the appropriate needle sewing head, rotating wheel, the needle rod rises to the highest point, unscrew the needle clamping screw. Insert the needle handle toward the left, insert the needle handle into the hole of the needle rod, and then to the bottom of the pin hole, then fix the screw. Note in Figure 1 and B, the needle handle not in the wrong direction, C needle groove is wrong.
1, the line is too thin, leading to easily broken line, you can try to replace the thicker lines.2 、 the adjustment of the computerized quilting head is not correct, and the head needs to be readjusted.
