Spun yarn testing machine

Abstract

The invention relates to a spun yarn testing machine. The spun yarn testing machine comprises a feeding mechanism, a drawing mechanism, a twisting and winding mechanism, an improved forming mechanism and a transmission control mechanism, wherein the forming mechanism consists of a main connection part, a lifting part and a step-up part; the main connection part consists of a forming cam, a fixing plate, a sliding chute, a slide block and a roller and is a core part of the forming mechanism; the lifting part consists of a ring rail lifting unit, a yarn guide plate lifting unit and a balancing unit; the step-up unit consists of a ratchet unit, a decelerating unit and a distance adjusting unit; and the transmission control mechanism consists of a touch screen, a programmable logic controller, four frequency converters and five asynchronous motors. The spun yarn testing machine has a compact structure and is easy to operate, the process is convenient to adjust, particularly the forming mechanism is low in manufacturing cost and has stable performance, spun yarn has high forming property and the spun yarn testing machine can be widely applied to optimization of each technological parameter of a spun yarn step and rapid reaction test of a sample in teaching, scientific research and production.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a spinning testing machine, which can be widely used in teaching, scientific research and production for rapid testing of various process parameters and samples of the spinning process. Background technique [0002] The spinning process is the last process from fiber to yarn in the spinning process, that is, through the four mechanical mechanisms of feeding, drafting, twisting and winding, forming, the roving is first spun into a certain thickness and conforms to the required For spun yarns required by respective product standards such as weaving, knitting or twisting, and finally the spun yarns that have been spun are wound on bobbins according to certain forming requirements by the forming mechanism, which is convenient for transportation, storage and subsequent processing, etc. The series of processes is called the spinning process. [0003] The processing mechanical device u...
