Maintenance of trimming parts
The cutting angle of the embroidery machine is between 285o and 286o. Some can set the cutting angle and the length of the thread. A simple method of adjusting the thread trimming cam is introduced, which is the most commonly used method by the author when repairing the thread trimming part.
Specific adjustment method: The machine is stopped at 100o, and the trimmer solenoid is held up by hand, and the trimmer swing pin enters the position where the trimming cam groove curve has the lowest arc. This is the best position for the trimmer cam installation and tightening. Thread trimming cam screw, the position of the thread trimming cam can be controlled by a small amount of forward and reverse movement. Note that when the thread-cutting swing pin enters the thread-cutting cam groove, there must be a gap between the pin in the groove to prevent the pin from being stuck in the groove during thread-cutting.
The principle of the embroidery electromechanical magnet thread trimming mechanism is the same as that of the computer sewing machine. If you find that some of the machine heads have poor thread trimming, you can check whether the position of the movable knife is too large, and whether the movable and fixed blades are worn. It is worth noting that the position of the thread trimming cam should not be changed under normal circumstances, and it can only be changed when most of the machine heads have poor thread trimming and overhaul.
