Embodiment 1
[0045] Such as image 3 As shown, the spinning tension on-line control method for realizing uniform tension spinning described in the present invention comprises the following steps:
[0046] (1) First, the spinning tension of the ring spinning frame is detected online by the spinning tension detection device;
[0047] In order to be able to realize the automatic detection of the spinning tension of the ring spinning frame, four functional requirements need to be met: first, the device is stable and does not affect the jointing, doffing and cleaning work of employees; second, the signal is automatically collected with the change of spinning tension Spinning equipment; the third is to process the collected signal and convert the data output function; the fourth is to obtain the test results to display on the screen, print or apply to control the spinning tension of the whole machine. Such as figure 1 , figure 2 As shown, the spinning tension detection device of the present ...
Embodiment 2
[0102] Spinning variety: C18.5tex, 11917r / min, main motor display 48Hz, spinning when the uniform tension system is off and on, and the data collection time is 30 minutes. The uniform tension control of spinning in the small yarn stage is 0.9 times of the maximum tension, and the online uniform tension control effect is as follows: Figure 9 , as shown in Table 2; the spinning uniform tension control in the middle yarn stage is 1.1 times of the maximum tension, and the online uniform tension control effect is as follows Figure 10 , as shown in Table 3; the spinning uniform tension control in the large yarn stage is 0.85 times of the maximum tension, and the online uniform tension control effect is as follows Figure 11 , Table 4. The yarn quality and yarn breakage rate after the uniform tension system is turned on are shown in Table 5 and Table 6.
