Computerized embroidery machine is by far the most advanced and complex sewing equipment integrating machine-electricity. Under computer control, the embroidery machine completes all patterns of sewing and embroidery. At present, the Tiger Brain embroidery machine has developed to a high-precision and high-efficiency model with 24 heads and 12 colors, and a large number of them are _12 heads 6 colors, lu. heads 6 colors, 10 heads 3 colors, 6 heads 6 colors, etc. series. They have made great contributions to the high-quality, high-tech and high-efficiency production of industrial products such as "body packaging". The computer and the machine head machinery are the main body of the embroidery machine. However, one of the main components to realize the automatic operation and control of the machine head machinery by the computer is the photoelectric incremental encoder.
The role of the photoelectric incremental encoder in the computerized embroidery machine. There are mainly two aspects: 1. Determine the position of the needle bar of the head; 2. Detect the speed of the embroidery machine.
The computerized embroidery machine decomposes the movement trajectory of the embroidery sample into several sub-samples, and the computer realizes the movement of the sub-samples through stepping motors in the X and Y directions to automatically move the shed and needle needles. After the shed frame of the fixed embroidery moves one step forward in the X and Y directions, the embroidery needle on the machine head pierces the embroidery, and the computer continuously sends embroidery to the stepping motors in the x and Y directions according to the embroidery track data Data, the stepper motor will move once, and the needle will embroider one stitch at a certain step. The movement of the needle bar of the machine head is driven by the rotation of the electromagnetic clutch motor in the z direction: with the help of the mechanical mechanism, the rotation of the motor is transformed into the linear motion of the needle bar of the machine head. Every time the motor rotates, The needle bar goes back and forth once ~ the needle pierces the embroidery at a certain step. So, how can the movement of the needle bar and the movement of the shed be carried out in an accurate and coordinated manner? This is achieved by a photoelectric incremental encoder fixed on the z electric shaft.
