The composition of an air spinning machine mainly includes the following key parts:
1、 Main structural components
Spinning chamber: The core part of an air spinning machine, used to draw fiber strips into fine filaments and form yarn. The spinning chamber usually contains a spinning cup (or rotor), which is a high-speed rotating metal cup that produces centrifugal force to condense and twist fibers into yarn.
Nozzle: A component used to draw fiber strips into fine filaments, and to stretch and refine the fibers by spraying air flow.
Combing roller: used to grab and comb the cotton fibers fed in, and to throw out the fibers through the centrifugal force generated by its high-speed rotation, providing single fibers for the subsequent spinning process.
Feeding system: including feeding horn, feeding roller, feeding plate and other components, responsible for conveying fiber strips to the carding roller for cotton cleaning treatment.
Impurity removal device: used to remove impurities and short fibers from fibers, ensuring the quality of fibers entering the spinning cup.
Thread guide tube and thread guide roller: responsible for exporting and winding the spun yarn into tube yarn.
2、 Auxiliary components and devices
Hollow spindle (some models may not use it): In the design of some air-jet spinning machines, hollow spindles are used to carry components such as spinning chambers and rollers, but in modern air-jet spinning technology, the spinning cup rotates directly at high speed, eliminating the need for traditional spindles.
Roller and roller: In some air flow spinning machines, these components are used to transfer filaments and yarns to the twisting mechanism, but in modern air flow spinning technology, this step is usually accomplished through the rotation of the spinning cup and components such as the yarn guide tube.
Twisting mechanism (which may not directly appear in some air-jet spinning machines): Although air-jet spinning mainly relies on the airflow generated by the rotation of the spinning cup for twisting, some models may still have additional twisting mechanisms to enhance the twist and strength of the yarn.
Exhaust device: used to extract air from the spinning cup during the spinning process, creating negative pressure that helps with fiber transport, slip, coalescence, and twisting.
3、 Control system
Airflow spinning machines are typically equipped with advanced control systems, including touch screens, PLCs, etc., for setting spinning parameters, monitoring the spinning process, achieving automation control, and fault diagnosis.
In summary, the composition of the air-jet spinning machine is complex and delicate, with various components working together to complete the spinning process from fiber strands to yarn.
