  Abstract:In order to carry out compact spinning transformation of RY5 collective doffing spinning frame，the points for attention during the transformation of four rollers negative pressure compact spinning are analyzed and the transformation scheme is formulated.That is，by moving the front，middle and rear rollers of the head of RY5 collective doffing spinning frame 30 mm back along the 45° direction of the drafting plane，the assembled spinning device and the guide cots are moved back synchronously，and the eccentric structure small gear box are installed to drive front and bottom rollers between the output end of the front and bottom rollers and the connected roller head segment；the middle and rear lower rollers move backward through the sliding seat and use the rotating rocker arm for gear meshing transmission；special high-type compact spinning roller seat is made in the rear of the vehicle，the cotton suction air duct in the rear of the vehicle and its opening are translated by two spindle distances with special cotton suction air duct，and S-shaped rubber connecting pipe is customized to connect the pipe and cotton suction air duct.By comparing the yarn quality before and after the transformation，it is shown that the transformation scheme of RY5 collective doffing spinning frame has low cost and short cycle，and the yarn quality has been improved after the transformation.
Key Words:RY5 collective doffing spinning frame；compact spinning device；bobbin grabber；guide cot；tube；cotton suction air duct；evenness CV
