Description

Conducting bar device

Technical Field

The utility model relates to a spinning equipment technical field especially indicates a conducting bar device.

Background

Blending of different raw materials in the drawing process, especially strip blending, is increasingly important for the composition control of yarns and even fabrics. Compared with raw material mixing, the strip mixing can more accurately control the mixing proportion, saves the cost, and has simple operation and definite process. Under the requirements of fabric consumers and yarn purchasing manufacturers, more and more yarn manufacturers adopt a strip mixing process to produce the fabric. At present, a drawing frame enables fibers in slivers to achieve a mixing effect in the process of drawing and fine drawing of the slivers by drawing and combining the feeding slivers, but the mixing effect is not obvious. In order to achieve the desired mixing effect, manufacturers have to improve the mixing effect of the fibers in the sliver by repeating the combining process for many times. For example, in the production process of polyester/cotton blended yarn with a polyester/cotton blending ratio of 35/65, 3-4 drawing and mixing processes are required to achieve a good mixing effect.

However, the repeated strip mixing process not only increases the production flow and reduces the production efficiency, but also increases the production cost such as personnel energy consumption and the like; after repeated combination drafting, the cohesive force between fibers in the slivers is greatly reduced, so that the slivers are easy to break in the subsequent production process, and the production efficiency is influenced; slivers are also prone to accidental drafting, leading to deterioration of the evenness, additional detail, etc. Therefore, slivers of different raw materials can be drawn by a drawing frame to achieve better mixing effect of the fibers, and the method has very important significance. By analyzing the drafting principle of the drawing frame and the motion of the fiber in the drafting process, a sliver guide device is additionally arranged at the feeding end of the drafting roller stand, so that the sliver is arranged according to certain requirements before entering the drafting zone, and the aim of improving the mixing effect is fulfilled. Chinese patent application publication No. CN 106132856 a discloses a sliver guide of a drafting device and a drafting device, in which the related sliver guide can be used to control the moving path of the fed fiber sliver, control the fiber sliver to enter the drafting system according to the overlapping of the double-layer fiber slivers, and improve the mixing effect of the fiber slivers during the drafting process, but the problem of the patent is that the fiber sliver output by the fiber sliver guide has serious quality problems in the actual production, specifically, the fiber sliver guide frequently generates a flying phenomenon in the subsequent roving process, and normal production cannot be performed.
