It can efficiently complete the twisting work and produce yarns with different twists to meet the needs of various textiles. The transmission device of the staple fiber two-for-one twister is used to ensure the coordinated operation of various components, so that the yarn can efficiently complete the twisting and winding of the staple fibers after exiting the feeding bobbin.

[0003] Prior art includes a utility model with publication number CN2567243Y. This utility model relates to the field of twisting equipment, specifically comprising a frame, a motor, and a transmission mechanism at both ends of the frame. The frame is provided with a winding and forming mechanism and a spindle plate, on which spindles and a tensioning pulley are mounted. A tangential belt driven by a motor frictionally engages with the spindles and tensioning pulley. The utility model is characterized in that the spindles are arranged in a quasi-arc shape on the spindle plate, with the tensioning pulleys located at both ends of the quasi-arc shape. This significantly reduces the number of tensioning pulleys, and speed regulation is conveniently performed using an AC motor drive. However, during the twisting process, after prolonged use, the belt and spindle become loose, resulting in inflexible rotation of the spindles and affecting the twisting efficiency of the equipment.

[0004] In order to solve the problem of looseness between the belt and the spindle, which causes the spindle to rotate inflexibly and affects the twisting efficiency of the equipment, the existing technology adopts the method of disassembling and replacing the belt, but it increases the maintenance burden of the equipment, which in turn leads to the problem of low equipment processing efficiency.
