Technical Field

[0001] The utility model relates to the technical field of drawing frames, in particular to a raw sliver combing device for drawing frames. Background Art

[0002] The draw frame is a spinning machine used to process several carded or combed fiber strips into fiber strips with certain quality requirements during the production process. The function of the draw frame is to improve the internal structure of the strips, thereby improving the uniformity of its long segments, while reducing the weight unevenness, making the fibers in the strips straight and parallel, reducing hooks, making the fineness meet the requirements, and making the raw materials of different types or qualities mix evenly to achieve the specified mixing ratio.

[0003] At present, the T19 new drawing frame uses a conical cotton fork in the process of combing the raw sliver. During the combing process, the raw sliver will fluctuate due to the traction of the machine, so that the raw sliver will pass through two adjacent conical cotton forks, resulting in changes in the spacing between the conical cotton forks combing the raw sliver, which can easily lead to poor formation and knotting of the raw sliver. The knotted raw sliver enters the concave and convex rollers, which makes the double-sided toothed belt too tense, often causing broken teeth, a high rate of breakdown, affecting operating efficiency, and increasing workload and machine material consumption. Therefore, it is urgent to solve this problem.
