Basic treatment methods for common faults of computer embroidery machine
Computer embroidery machine is the most advanced embroidery machine in contemporary times, which can make the traditional manual embroidery achieve high speed and high efficiency, and can also achieve the requirements of "multi-level, multi-functional, **** and perfect" that manual embroidery can not achieve. So, what are the basic treatment methods for common faults of computer embroidery machines? Let the editor tell you below!
1. Disconnection
There are two cases of wire breakage, one with regular disconnection and one with irregular disconnection. Regular disconnections are:
1. The gap between the needle and the hook is not correct, the needle position is too high or too low, and it needs to be readjusted.
2. The machine pinhole and needle plate hole have burrs, the hook has burrs, and the positioning hook has burrs.
3. The wire crossing part is not smooth, including the clamping board, clamping screw, wire rod hole, upper and lower wire frame, etc., all unsmooth or burrs must be processed smooth or replaced.
4. The needle is installed backwards, and it needs to be reinstalled correctly, the needle tip is damaged, the needle is stained with glue, and the needle is replaced.
5. If the wire cam is damaged, replace the wire cam.
6. The spindle is channeling.
7. There are scratches and damage on the line surface of the hook.
Irregular disconnections are:
1. The ambient humidity is too high, the line is damp, dehumidify, replace the new line.
2. The needle is unreasonable. Revision.
3. The quality of the thread does not meet the requirements, the installed thread is not in line with the requirements, the embroidery thread is too thick, and the specifications of the needle are not matched. Swap and reinstall.
4. The moving frame curve and frame shift angle are unreasonable, adjust the computer parameters.
5. The upper and lower shaft transmission has a gap or shaft breakage, causing the machine head and the hook to be out of sync. Check the gearbox, adjust the chain tightening or gearbox timing belt. 6. The surface of the embroidery thread is rough. Add silicone oil to the surface of the embroidery thread.
　Second, block the line
Blocking the thread is when the thread forms a ball under the needle board, blocking the pinhole, and the consequence is that the thread is broken.
1. The gap between the positioning hook and the shuttle frame gap is unreasonable. Readjust.
2. The embroidery is too thin or too loose, and the needle board hole is too large. Pad two or three layers of non-woven paper.
3. The buckle line fails. Check the buckle
4. The bottom line is too loose, and the direction of the line is not right. Adjust the bottom line.
5. There are debris or deformation in the shuttle shell, which causes the spindle to rotate smoothly and is easy to break the bottom line.
3. Broken needle
1. The needle is bent and the screw is loose. The needle and pin screw need to be swapped.
2. The gap between the hook and the needle is too small. Adjust the mating clearance.
3. The pressure of the clamping plate is too tight, the tension of the face line is too large, adjust the tension.
4. The press foot hole, needle plate hole and machine needle are not aligned.
5. The frame shift angle is not correct, adjust the frame shift angle.
6. The quality of the needle is not good, replace the needle.
7. Offset the position of the hook, adjust the hook.
Fourth, jump the needle
1. The needle and the hook do not cooperate well, the needle is too high, and the gap is too large. Adjust the needle height and low position.
2. The hook is damaged. Change the hook.
3. The spring under the pin bar is broken. Swap the lower spring.
4. The embroidery surface is too loose. Tight embroidered fabric.
5. The pressing foot is too high or deformed. Adjust or swap the presser feet. (When the needle stops, the gap between the press foot and the needle plate is 0.5mm-1.5mm) depends on the thickness of the fabric.
5. Parabolic lines, floating lines
1. The tension between the face line and the bottom line is too small and too loose. Adjust the tension.
2. The quality of the line is not good. Swap the line.
3. Insufficient lubrication of the hook. Refill oil (twice per shift)
6. Pattern shifting, deformation
There are many cases of pattern shift, X direction shift, Y direction shift, overall shift, individual head shift, unidirectional shift, irregular shift and so on.
1. The overall shift in the X direction, the mechanical part of the failure includes: the stepper motor coupling is loose, the timing belt is too loose or too tight, the timing wheel bearing, prismatic bearing, and bandage bearing are damaged, and the guide rail clearance is too large.
2. The overall shift in the Y direction, the fault is the same as the X direction, but the direction is different.
3. The overall displacement, in addition to mechanical reasons, there are also electronic control failures and patterning reasons, and the electronic control part of the fault is:
(1) Memory failure, need ** computer memory tricks, formatting. Then re-enter the pattern. Generally, the computer should not store too many patterns, the storage time should not be too long, and the patterns should be cleaned up regularly.
(2) Interference caused by grid interference, leakage of electromagnets or other electrical components. It is necessary to find the source of interference and eliminate interference.
(3) There is no power failure protection, sudden power failure, need to relocate and find the original position.
(4) Stepper motor failure, most of the reason is that the stepper motor drive is damaged, repair or replace the drive.
(5) Encoder failure, self-test encoder in the computer.
