★ Introduction to the texturing machineThe structure of the ◇ texturing machine is generally set to a symmetrical A side (left side) and a B side (right side), and an upper hot box and a lower hot box are respectively installed on each side, and a heater is installed on each hot box. And temperature sensors, which form the heating and measuring section of the texturing machine. The transmission system of the texturing machine generally uses multiple frequency converters to separately control the speed of each transmission component. Through the speed measuring sensor (encoder or proximity switch) mounted on the transmission component, the speed of each frequency converter is measured and controlled to meet the stretching and The technical requirements of the false twist, so the closed-loop constant speed control of the frequency converter is very important.
◇This article is composed of 11 inverters in one of the texturing machine case analysis systems (2.2 eight k sets w, 1.5k sets w, two 7.5kw / one set of 5, k points w do not control left one roller, right one Rolla, left second roller, right second roller, left three roller, right three roller, left roller, right roller, left traverse mechanism, right traverse mechanism, dragon belt), two of the inverters need to have a disturbance function (a kind The special function of textile transmission can also be called triangle wave function.), mainly used to control the traverse mechanism; the rest of the transmission part requires high speed and accuracy, and needs to have speed feedback function. In order to save cost, The general pulse signal is provided by an external proximity switch.
★ Motion Control System
◇ constant speed control
◇ In order to effectively control and count the length and twist of the false twisted wire, each frequency conversion in the system needs an infinite loop to stabilize the speed, that is to say, each frequency conversion must have a pulse feedback function.
◇Speed swing control
The swaying frequency function is suitable for textile, chemical fiber and the need for winding, lateral movement and other occasions.
