The utility model discloses a lifting device for the yarn guide roller of a rotor spinning machine, which comprises a rotating arm, a pressing rod, an ejector rod, a spring, a drum bracket which drives the automatic lifting of the yarn drum and a drum lifting cylinder; the drum bracket is installed through a rotating shaft support, and the upper ends of the drum lifting cylinder piston and the spindle rod are hinged with the drum bracket, and the rotating arm and the pressing rod are hinged The middle part is supported and installed by a rotating shaft. The leading roller is installed on the rotating arm. The front end of the pressing rod is pressed against the rotating arm. The lower end of the top rod is provided with a long groove hole. The back end of the pressing rod is installed in the long groove hole. The top rod rises and drives the rotating arm to rotate forward through the pressing rod drive, which drives the leading roller to lift off the spinning shaft. The upper part of the rotating arm is set up. Spring shoulder, one end of the spring is fixed, the other end is top of the spring shoulder on the rotating arm. The spring elastic force drives the rotating arm to reset and reverse rotation to drive the yarn roller to drop pressure against the spinning shaft. The problem of asynchronism of yarn introduction and winding in the existing rotor spinning machine is solved by using the same cylinder to drive the yarn drum lifting and the yarn drawing roller lifting.

转杯纺纱机引纱皮辊抬升装置
本技术属于纺纱机零部件装置,尤其与一种转杯纺纱机引纱皮辊抬升装置有关。
技术介绍
转杯纺纱机的纺纱原理是将纤维条开松成单纤维,单纤维随气流输送到高速回转的转杯内,在凝聚槽内形成纱尾,同时被加捻成纱,然后由引纱轴和引纱皮辊组成的引纱罗拉引出,再由卷绕装置直接绕成纱筒。现有转杯纺纱机纺纱停止时,手动或气动驱动纱筒抬起脱离卷绕摩擦辊,手动驱动引纱皮辊抬起脱离引纱轴并由专门的锁紧机构锁住引纱皮辊抬升状态。纺纱启动接头时,先由沉纱电磁铁解除挂纱,让纱头进入纺纱器的引纱孔到达转杯,与转杯内的纤维接触,然后手动或气动驱动纱筒降落压在卷绕摩擦辊上,由专门的电磁铁驱动解除抬升锁紧状态使引纱皮辊抬升降落压在不停转动的引纱轴上,引纱和卷绕由两个动力源驱动,同步性差,影响接头和纱筒成型质量。
