The invention relates to a spinning device and a parallel spinning method with the same. The spinning device is characterized in that a spinning vibrator is arranged between a front roller and a guidewire and comprises at least one pair of vibratory agglomeration rollers, and the vibratory agglomeration rollers in the pair are two agglomeration rollers which are arranged on the two sides of a fiber strand and symmetrically vibrate; the symmetrical vibration direction does not include the fiber strand moving direction; the axial angle of the two rollers is 0 degree to 10 degrees; when the tworollers are static, the axis of the fiber strand and the axes of the two rollers are located in the same plane. The spinning method includes the steps that the fiber strand is agglomerated and subjected to resistant twisting through the vibratory agglomeration rollers to be prepared into yarn, and the running direction of the fiber strand is perpendicular to the vibration direction of the agglomeration rollers, wherein agglomeration means that the fiber strand is vibrated through the agglomeration rollers, and wandering fibers suffer from agglomeration acting force to be wrapped and wound in the fiber strand, resistant twisting means that the agglomeration rollers are in contact with the fiber strand to generate friction force, and the resistant twisting torque is generated in the processthat the fiber strand is twisted back and transferred upwards, and parallel spinning is achieved by lengthening a twisting trigonum. The spinning device is simple in structure and low in cost; hairiness is reduced with the spinning method.
