Problems solved by technology

It can be seen that there is no high-speed and low-wear high-speed rotary twisting that directly drives the mechanical twisting spindle directly through the airflow, which cannot solve the problem of large wear of parts, high energy consumption, inconsistent tension and contact force, and transmission efficiency between spindles during the belt drive process. A series of problems such as large differences

Abstract

The invention relates to a pneumatic magnetic suspension type twisting device and its application, and belongs to the technical field of textiles. The dynamic magnetic suspension type twisting device of the present invention is composed of a magnetic suspension rotor, a spindle rod joint, a support plate, and a magnetic air flow seat. The magnetic suspension rotor is suspended in the magnetic air flow seat fixedly installed on the support plate. The uniform and symmetrical nozzle sprays the blades on the magnetic levitation rotor, so that the non-contact jet air flow of the nozzle drives the magnetic levitation rotor to run at high speed, and realizes the high-speed operation of the air-driven twisting mechanism with low wear, long cycle, consistent and stable, and oil-free lubrication. The device of the invention is applied to the ring spinning frame or the double twisting spinning machine or the double twisting machine, and replaces the traditional twisting mechanism that is complex and easy to wear such as the original dragon tendon, belt and spindle seat, and solves the problem that the traditional twisting mechanism is easy to wear and tear. , the single-spindle is not adjustable, etc., and the yarn twisting production with low wear, high speed, and single-spindle adjustable is realized.

Description

technical field [0001] The invention relates to a spinning method, in particular to a pneumatic magnetic suspension twisting device and its application, belonging to the technical field of textiles. [0002] technical background [0003] Spinning is the process of orderly arranging the messy loose fibers in sequence, such as opening, carding, drafting, etc., and then performing linear convergence and twisting. Different twisting methods directly determine the structure and efficiency of the yarn produced by spinning. Under normal circumstances, according to the holding state of the yarn during twisting and rotation, it can be divided into two types: twisting at the holding end and twisting at the free end; according to the force source that directly drives the yarn to rotate, it can be divided into: mechanical parts rotate to drive the yarn The sliver is twisted into a yarn, and the air blows the sliver fiber to rotate and wrap it into a yarn. The rotating mechanical parts ...
