An intelligent disc tension device and its applied precision winder

Abstract

The invention discloses an intelligent plate type tension device and a precision winding machine applied to the same. The intelligent plate type tension device comprises a support (1), a yarn guide assembly (2) and a tension adjusting assembly (3), the yarn guide assembly (2) and the tension adjusting assembly (3) are arranged on the support (1), the yarn guide assembly (2) comprises a tension disc (201) arranged on the support (1) and a tension plate (202) matched with the tension disc (201), the tension adjusting assembly (3) comprises a servo motor (301), and an output shaft of the servo motor (301) is fixedly connected with a cam disc (302) which rotates along with the output shaft and drives the tension plate (202) to collide with the tension disc (201) to generate tension. In the winding production process, the servo motor automatically rotates to drive the cam disc to rotate to change the rotating angle of the cam disc according to the diameter change of yarn winding, the specific difference between yarn and received signals, the tension on the yarn between the tension plate and the tension disc is changed, tension differences between all spindles are corrected, and therefore it is guaranteed that high-quality winding with good forming and even density is obtained.

Description

【Technical field】 [0001] The invention belongs to the field of textile machinery, and relates to an intelligent disc tension device and a precision winder for its application. 【Background technique】 [0002] In textile processing, yarn tension is a very important parameter. The tension and stability are directly related to the quality level of the final product, production efficiency and the smooth progress of downstream processes. If the tension is too small, the volume of the package is small and the shape is poor, and it is easy to cause stripping and end breakage during unwinding; if the tension is too high, the yarn will be stretched too much, which will affect the strength and elasticity of the yarn and cause damage to the yarn ; Unstable tension will cause uneven package density, which will have adverse effects on subsequent dyeing or weaving. Therefore, proper and stable tension is an important guarantee for obtaining high-quality packages. During the winding proc...

AI Technical Summary

Problems solved by technology

However, as mentioned above, the source of yarn tension is more complicated, and the back pressure performance of the cradle and the change of package diameter will have a great impact on the final package

During the whole winding process of the existing disc tension device, the applied tension value is relatively constant, and at most it can only be adjusted manually, and cannot be adjusted automatically according to the dynamic change of tension

Moreover, there are differences in the tension between the various spindle positions, and the existing device cannot effectively compensate, thereby eliminating the tension difference between the spindle positions

This will cause two important technical problems: uneven density inside and outside the same package and differences in package density and molding produced by different positioning

This technical problem has seriously affected the quality of the final package and the implementation of subsequent processes
