Problems solved by technology

[0002] The main drafting area of ​​the roller drafting mechanism of the spinning machine generally adopts the upper and lower double aprons to draw the yarn, so that the fibers in the fiber sliver are controlled by the friction boundary formed by the upper and lower aprons during the speed change process, and the fiber sliver is uniformly drawn. , the control of the fiber in the main drafting zone is very critical to the yarn formation. The traditional double apron elastic yarn drawing has a good control effect on the fiber sliver, but in the traditional double apron form, the lower apron is set on the On the middle roller, when replacing the lower apron, the middle roller needs to be disassembled. At the same time, the roller with the apron has a relatively large driving load and consumes a lot of energy. The improvement of the yarn drawing method is also a technology that people continue to explore, such as patent applications CN201822092749.X "A traction assembly and a traction kit of a ring spinning machine" proposes a lower apron mechanism assembly, which can replace the lower apron more conveniently than traditional mechanisms. Patent application CN201711096466.6 "spun yarn The DS curve drafting system of the machine "proposes to cancel the drafting mechanism of the lower apron. These studies are intended to change the traditional double apron structure, but the problem is that the former scheme significantly increases the complexity of the mechanism. The latter scheme has completely changed the friction force formed by the traditional double-apron yarn delivery system on fibers. Currently, the technical improvement of the traditional double-apron yarn delivery system is still in progress.

Abstract

The invention discloses a guide method for fibers in a main drafting area of a roller drafting mechanism. According to the roller drafting mechanism, an upper middle roller presses a middle roller anda lower guide ring roller to form two jaws, the jaw formed by the middle roller and the upper middle roller clamps and drives an upper guide ring, the upper middle roller and the lower guide ring roller simultaneously clamp the upper guide ring and a lower guide ring, the lower guide ring is controlled and driven by the jaw formed by the upper middle roller and the lower guide ring roller, and afiber bar is fed in from the jaw formed by the middle roller and the upper middle roller, enters a guide channel formed by the upper guide ring and the lower guide ring from the jaw formed by the upper middle roller and the lower guide ring roller and is guided to be fed into a front roller jaw under the elastic control of the upper guide ring and the lower guide ring.
