Technical field:
the invention relates to a tension ball displacement control device capable of tilting a two-for-one twisting spindle, and belongs to the technical field of spinning equipment.
The background technology is as follows:
the two-for-one twisting device is popular for a long time because of the advantages of high production efficiency, low energy consumption, large package quantity, low running noise and the like. However, the complexity of operation greatly reduces the production efficiency, and the labor cost is high and becomes a bottleneck for restricting the development of the product. Because the tension device of the filament double-twist spindle is different from the tension device of the short-fiber double-twist spindle, a pneumatic threading system of the short-fiber double-twist spindle is developed in the 90 s of the last century abroad, the complex operation of threading by a lifting operator is fundamentally solved, the production efficiency is improved unprecedentedly, and the labor cost is further reduced. Laying a foundation for realizing full-automatic unmanned operation. For many years, the study of realizing pneumatic threading of the filament double-twisting spindle has never been stopped, but the pneumatic threading operation of the filament double-twisting spindle is not realized. The design and improvement of the spindle are not the technical problems, and the technical problems which are not broken through all the time to the present fall onto the tension device of the filament two-for-one twisting spindle. The tension device of the filament double-twist spindle consists of a tension tube, a plurality of tension ball bracket grooves, metal tension balls, tension ball bracket groove interval positioning support sleeves, tension tube caps, metal guide wire neck plates and other parts.
