Color change or needle position analysis and maintenance of computer pattern machine:
The color change abnormality of the computer pattern machine mainly includes the following aspects: the color change is not in place, the color change is not changed, the color change is limited, the color change timeout is two seconds, and the color change semi-turn abnormality is performed. For abnormal needle position, you can use a wrench to move the color change cam on the color change box. If there is a feeling of stuck, it is generally that the needle bar of a certain machine head does not go up, or the take-up pole falls, or the drive tooth on the drive wheel and the pick-up tooth height or gap are incorrect. If it is easy to pull up, if you can drive after you reach the needle position, there may be a failure of the color change power board. When normal, both indicators on the needle position detection board on the color change box are lit. If the above does not light, the following will not appear, it will appear. If the needle position abnormality (or E-57) is mostly the needle position detection board is faulty, or there is a problem with the motherboard, there may be a color change abnormality caused by the decoder board. First check whether the connectors on the power board are firmly connected. If the connector ferrule is damaged, replace the damaged connector ferrule. Next, check if the fuse on the power board is blown, and if it is blown, replace the fuse. When there is a clockwise color change, and the counterclockwise does not change color, or counterclockwise color change, and clockwise does not change color, the method is the same as above. When the direction is reversed, the color can be changed, but each time the color change is exceeded, the power board should be removed to check whether the diode (D1, D2) is damaged. If it is damaged, replace the damaged device.
