Description

Technical Field

[0001] The utility model specifically relates to the technical field of torsion spring tensioning components, in particular to a high-efficiency compactly spun negative pressure tube grid ring matched torsion spring tensioning component. Background Art

[0002] Compact spinning is a new spinning technology that is carried out on an improved new ring spinning frame. Its spinning mechanism is mainly: a fiber cohesion zone is added in front of the traction device of the ring spinning frame, which basically eliminates the spinning twisting triangle between the front roller and the twisting point. After the fiber strands are output from the front mouth of the front roller, they first pass through the mesh leather ring on the outer jacket of the special-shaped suction tube. The strands move on the mesh leather ring. Due to the contraction and polymerization of the airflow, the strands are gathered and rotated through the suction groove of the special-shaped tube, gradually turning from a flat belt to a cylinder. The ends of the fibers are twisted into the yarn, so the yarn is very compact, the yarn appearance is smooth, and the hairiness is less.

[0003] The mesh ring tensioning components previously used in compact spinning equipment are very prone to flower accumulation, which may cause the mesh ring to deviate at the least or be damaged at the worst. In this way, there is no way to effectively ensure the coordination between the mesh ring and the paddle during use.

[0004] In view of the above situation, we provide a high-efficiency compact spinning negative pressure tube mesh ring with torsion spring tensioning assembly. In this device, the paddle plate is installed on the tensioning rod. The paddle plate and the negative pressure groove are matched by rotating the paddle plate, and then the paddle plate is fixed by the mesh ring. When fixing, the two ends of the paddle plate away from the opening tube are provided with raised parts. In this way, when cooperating with the mesh ring, the mesh ring can be effectively prevented from being offset and causing flower accumulation, thereby effectively ensuring the working efficiency and quality of the negative pressure tube.
