Negative pressure guide capturing type smooth and clean spinning device

Abstract

The invention relates to a negative pressure guide capturing type smooth and clean spinning device and belongs to the technical field of textile processing. A holding groove is formed in the working face of a heating component, a suction inlet is located in the inner wall of the holding groove, is communicated with a suction channel of the heating component and a channel of a base and is communicated with a suction flute through the base, negative pressure airflow is generated in the holding groove through the suction inlet, fiber at the edge of a fiber strand is guided to be tightly attached to the sliver body for capture, a movable cover board is movably installed on a mechanism on a cover board installation table through a hinge, connection of fine yarns is facilitated, it is ensured that negative pressure airflow enters only from the inlet end of the holding groove in the normal spinning process, and the negative pressure airflow is fully used for guiding and capturing the fiber and holding and winding fiber hairiness. Meanwhile, the ironing type smooth and clean spinning function and the airflow guide capturing type ring spinning function are combined, the fiber is captured more effectively, the fiber hairiness is eliminated more effectively, and the quality of finished yarns is improved. The negative pressure guide capturing type smooth and clean spinning device is reasonable in structure, convenient to operate and easy to use and popularize.

Description

technical field [0001] The invention relates to a negative pressure guiding and catching type soft and smooth spinning device, which belongs to the technical field of textile processing. technical background [0002] Hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness not only affects the production efficiency of weaving, knitting and other post-processes, but also affects the appearance quality of the final product. Especially today, when high-speed shuttleless looms are widely used, reducing yarn hairiness is of great significance. [0003] Yarn hairiness occurs during the spinning process of ring spinning. The key problem in the spinning process of ordinary ring spinning is: the front roller jaws press the fiber strands into a flat ribbon shape, and under the action of twisting torsion, the fibers in the flat ribbon fiber strands are transferred from inside to outside, when the fibers A certain part has entered the yarn body throu...

Problems solved by technology

The key problem in the spinning process of ordinary ring spinning is: the front roller jaws press the fiber strands into a flat ribbon shape, and under the action of twisting torsion, the fibers in the flat ribbon fiber strands are transferred from inside to outside, when the fibers A certain part has entered the yarn body through internal and external transfer. At this time, the head end of the fiber exposed from the yarn body is out of the grip of the front roller jaw, and cannot enter or wrap around the main body of the yarn body again, thus forming hairiness; when the fiber is in the At the edge of the flat ribbon-shaped fiber strands, the adhesion and cohesion between the fibers and the main body of the twisted strands is weak. As soon as the fibers come out of the nip of the fro
