Plotter: a device that can automatically draw graphics as needed. It can output computer output information in the form of graphics. Plotter is generally composed of driving motor, interpolator, control circuit, drawing table, pen holder, mechanical transmission and other parts. In addition to the necessary hardware equipment, the plotter must also be equipped with rich drawing software. Only the combination of software and hardware can realize automatic drawing. Software includes basic software and application software. There are many kinds of plotters, which can be divided into two categories according to their structure and working principle:
① Drum plotter. When the X-direction stepping motor drives the drum to rotate through the transmission mechanism, the sprocket drives the traction to move, thus realizing the movement in the X direction. The movement in Y direction is realized by the pen holder driven by Y stepping motor. The plotter has compact structure and large drawing format. But it needs a special kind of drawing paper with chain holes on both sides.
② Platform plotter. A cross beam is installed on the drawing platform, a pen container is installed on the cross beam, and drawing paper is fixed on the platform. The x-direction stepping motor drives the beam and the pen holder to move in the x direction; The Y stepping motor drives the pen holder to move in the Y direction along the beam guide rail. There are three methods to fix the drawings on the platform, namely vacuum adsorption, electrostatic adsorption and magnetic strip compaction. Platform plotter has high drawing accuracy, no special requirements for drawings and is widely used.
Numbering machine: According to the requirements of clothing style and fabric width, the patterns of all parts of the whole clothing are accurately arranged in the form of the least cloth, drawn on paper and printed out, and the output paper is called the numbering frame. This kind of paper that lists all parts of the whole dress is called a marking frame, so it is called a marking machine. The role of the logo frame is to determine the length and position of the cloth; As the basis of cloth cutting; It is also used for material calculation.
A complete marking machine * * * consists of five parts: marking information area, marking proportion input area, marking pattern area, cutting clothes quantity area and marking picture display area.
