Problems solved by technology

[0004] The above method takes few samples and is a kind of destructive sampling. It belongs to the post-evaluation of product quality and cannot control the processing parameters of silk thread in time. It is used to adjust the processing parameters in time to make the yarn characteristics tend to the design value, often resulting in a lot of waste products

Embodiment 1

[0066] like figure 1 As shown, the silk thread to be tested is input from the input terminal A, wound around five power wheels 1, and then output from the output terminal B; the designed tensile force value of the tested silk thread is F t =50N.

[0067]In this embodiment, the five power wheels 1 are respectively provided with a damping system and provide stable damping torque. Under the action of the traction system (not shown in the figure), the wire runs from the input end A to the output end B, so that the tension value of the wire increases along the traveling direction of the wire. Control the tension value F of the silk thread input end through the movable pulley (not shown in the figure) carrying the counterweight a is 10N. There are 5 power wheels 1 in the present embodiment, through actual measurement data, each correlation coefficient Q imax >0.6, each correlation coefficient Q i Take 0.4 for both, and the tension variables provided to the silk by the five powe...

Embodiment 2

[0078] like figure 2 As shown, the wire to be detected is input by the first guide wheel 31 arranged at the input end A, passes through five power wheels 1, and is output by the second guide wheel 32 arranged at the output end B. The design resistance of the wire to be detected is The pull value is F t =50N.

[0079] In this embodiment, the five power wheels 1 are respectively provided with a driving system and provide a stable driving torque. Under the action of the traction system (not shown in the figure), the silk thread runs from the input end A to the output end B, so that the silk thread The tension value decreases along the direction of wire travel. Control the tension value F of the silk thread input end through the movable pulley (not shown in the figure) carrying the counterweight a It is 50N. There are 5 power wheels 1 in the present embodiment, through actual measurement data, each correlation coefficient Q imax >0.6, each correlation coefficient Q i Take 0...

Abstract

The invention discloses an on-line silk thread detection device and an on-line detection method. The on-line silk thread detection device comprises a tension increase and decrease unit and speed testing devices, wherein the tension increase and decrease unit comprises at least one power wheel for providing a stable driving moment or a damping moment; a driving system or a damping system is arranged on each power wheel; both sides of the tension increase and decrease unit are respectively an input end and an output of a silk thread; and the speed testing devices are arranged at the input end and the output ends to directly or indirectly test feeding speeds of silk threads. The on-line silk thread detection device disclosed by the invention is simple in structure, can be arranged in the silk thread processing process, and is capable of achieving on-line nondestructive detection on a whole silk thread section, and preventing the silk threads from being discarded because of detection damage.

Description

technical field [0001] The invention belongs to the field of silk threads, and in particular relates to an online detection device and an online detection method for silk threads. Background technique [0002] In the process of silk thread processing, factors such as raw silk quality, temperature, tensile force, elongation rate, wire speed, feeding speed, and material properties are constantly changing, resulting in large fluctuations in the mechanical properties of the processed silk thread. Therefore , It is necessary to detect the mechanical properties of the silk thread before or after processing, so as to correct the processing parameters or reject the unqualified raw silk. [0003] At present, the testing of the mechanical properties of the silk thread is generally carried out offline monitoring in the laboratory. Through destructive sampling, one or several sections of silk thread are intercepted, and the mechanical properties of the thread are tested on the tensile m...
