The five most common methods for repairing and adjusting intelligent sewing machines

The five most common methods for repairing and adjusting intelligent sewing machines are due to factors such as loose screws, displacement of parts, wear and tear, and bumps, which can cause problems on the stitching material during normal use. Common drawbacks include floating lines, jumpers, non circular spaces, broken lines, and ripple marks. Please adjust according to the following methods:
1、 Floating thread - The seam on the garment is too loose and floats on the surface. 1. Tighten the thread clamp nut. 2. Tighten the thread tension spring.
2、 Intelligent sewing machine skip stitch - the garment piece is not connected to the seam. 1. Fine adjust the adjustment screw on the lifting joint to gently touch the bottom surface of the triangular tip of the loop to make the large needle slant out of position. 2. Adjust the bias screw on the large needle swing head to make the large needle close to the V-shaped groove bottom of the hanging needle when entering the hanging needle. 3. Adjust the needle holder so that the needle touches the bearing, but not too tightly. 4. Adjust the relative orientation of the two groove camshafts slightly, so that the large needle penetrates from the center or slightly above the center of the coil on the forming triangle. The circular triangle should be positioned at the center of the plane where the large needle gives way when hooking.
3、 Intelligent sewing machine thread breakage 1. Moderately loosen the thread clamp nut or use only a single thread clamp. 2. Loosen the thread tension spring. 3. Adjust the pain screw on the needle arm so that the large needle does not rub against the clothes hanging needle. 4. Adjust the nut on the rocker arm connecting rod to align the large needle with the center of the V-shaped groove of the clothes hanging needle. 5. Slightly adjust (rotate) the orientation of the small cam to ensure that the sewing needle tip stays in sync with the V-shaped groove of the hanging needle.
4、 The space is not in a circle - when there is a gap between the garment pieces, the stitching is not in a circle. 1. Fine adjust the upper adjustment screw of the lifting joint or the biased screw on the large needle swing head to make the triangle and the direction of the large needle in the circle correct. 2. Adjust the orientation of the bending plate so that the bottom edge of the square hole is flush with the center of the hanging needle, and the large needle passes through the center of the square hole. 3. Fine tune the relative orientation of the left and right sides of the slot cam so that the large needle penetrates from the center or slightly above the straight direction of the forming triangle. When forming a triangular hook line, it should be located at the center of the plane where the large needle gives way. 5、 Wave stitch - unclear or drifting stitch on the garment piece. 1. The same row (column) of the garment piece should be threaded into the hanging needle. 2. Carefully proofread the hanging pin to ensure its height is consistent and the distance is even. 3. Replace the deformed large needle.
