Tension changes that can be caused by the tension control device of the quilt production line

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

When warping the quilt production line, it is necessary to make the yarn have a certain tension in China, so that the winding structure of the warping beam can be normal and have the necessary density for development. Therefore, we must add a tension control device. During warping, the yarn is subjected to Tension has a great influence on whether the production technology of weaving enterprises can be carried out smoothly. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Grinder A spinning machine that turns fiber strands into rovings.

The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. If the yarn tension is too large, the yarn elongation will be too large, which will increase the warp yarn breakage in weaving. Therefore, the weight of the tension field has become a very important process analysis index in my country in the process of warping process research and design. , plays a decisive role in warping quality management.

After passing through the tension device, the tension T of the yarn can be calculated by the following empirical formula: The influence of the distribution position of the package on the knot tension on the quilt production line The distribution of the creel position has a great relative to the warp tension, which directly affects the uniformity of the sheet. Tension warp yarn. Using 19tex cotton yarn, when the diameter of the large end face of the package is 120mm, and the weight of the tension ring is 2. Ground, the average horizontal tension of the package yarn in different geographical locations is measured, as shown in Table 3-1. It can be seen from the table that the average surface tension of the yarn in the middle layer of the creel has the least effect, and the lower layer and the yarn have a greater tension effect than the upper layer; the distribution and development law of the front, middle and rear rows is that the tension gradually increases from front to back.

This is because of the different lengths of the creel, the yarn unwinding, the angle of the yarn guide 17, the angle of the yarn and the yarn loop wrapping the yarn, the different angles of the series-capable guide eye and the different boxes and other factors, the scaling of the teeth.
