Maintenance of trimmed part of embroidery machine

The cutting action angle of the embroidery machine is between 285ºand 286º, some can set the cutting action angle and the hook proportion of the cutting length.

This paper introduces a method of adjusting the shearing cam which is most commonly used in repairing the shearing part. The specific adjusting method is as follows:

The embroidery machine stops at 100 and holds the shear line solenoid up by hand, just as the shear line cycloid pin enters the lowest curvature position of the shear line cam groove curve, which is the best position for installing the shear line cam. Tightening the shear line cam screw and slightly reversing the shear line cam position can control the length of the shear line head.

Note that when the shear cycloid pin enters the shear cam slot, Make sure there is a gap between the left and right of the pin in the groove to prevent the pin from sticking in the groove when cutting the thread. The principle of the solenoid wire shearing mechanism of the embroidery machine is the same as that of the computer sewing machine. If partial nose cutting is found to be poor, It can check whether the position of the moving knife is too large and whether the moving and fixed knife edges are worn.

It is important to note that the position of the shearing cam should not be changed in general, but only in the case of poor shearing and overhaul of most machine heads.
