Electric control system and method for slubby chenille yarn

Abstract

The invention discloses an electric control system and method for slubby chenille yarn. The electric control system comprises a power supply circuit and a PLC system which is connected to the power supply circuit. The PLC system is connected to a spindle motor and a roller motor through a frequency changer and an alternating current contactor respectively, the output end of the spindle motor is provided with a speed sensor which is used for detecting the speed of the output end of the spindle motor, and the speed sensor is connected to the PLC system. By arranging the speed sensor at the output end of the spindle motor, it can be ensured that the roller motor is not stopped under the condition that the spindle motor is not stopped, the problem is avoided that when the roller motor is stopped, and the spindle motor continues to conduct twisting, so that twisting degree of cloth cover is uneven.

Description

technical field [0001] The invention relates to the technical field of slub chenille yarn, in particular to an electrical control system and method for slub chenille yarn. Background technique [0002] Slub chenille yarn is a kind of yarn developed by ordinary inverter control method. Because the slub part is slightly thicker than the conventional part, which looks like a bulging belly, it is also called "big belly chenille yarn". ", the launch of this product has enriched the types of chenille products and made the cloth surface have a certain three-dimensional effect. However, after the product was launched for a period of time, customers reported that "regular ladder accumulation", "overlapping bamboo knots", "weird shape of bamboo knots resembling sharp peppers" and "bamboo knots falling off" appeared in some fabrics. Phenomenon. [0003] According to the analysis, the reasons for the above problems on the cloth surface are mainly in the following aspects: [0004] A:...

Problems solved by technology

[0006] C: There are two main reasons for the velvet removal of the bamboo joints: one is directly related to the dyeing and finishing process, and the other is the defect of the spinning process, that is, in the production process, due to process design problems, the pause at the bamboo joints is slightly longer , resulting in too much accumulation of short fleece, and at the same time, the twist is transferred to the conventional yarn, resulting in excessively high twist of the conventional yarn, while the twist at the slub is low, and it is easy to appear cashmere phenomenon

[0007] In addition, the roller motor in the prior art uses a button to stop the switching action, and the spindle motor and the roller motor use the same start button. After the staff operates the start button, the spindle motor and the roller motor receive the start command at the same time and start working at the same time. Similarly, At the end, it also stops synchronously, and even the roller motor stops before the spindle motor. Even if it is a synchronous stop, the output ends of the roller motor and the spindle motor usually have inertia when they stop, and they will continue after stopping. Working for a period of time, and the staff cannot control the order in which the two are completely stopped, often prone to uneven yarn twist, resulting in quality problems in the final finished cloth surface
