Abstract:In order to ensure that the feeding plate and feeding roller of rotor spinning frame have a certain gripping force on the sliver,and make sure that the sliver is grasped by the carding roller at a uniform speed without damaging the cotton fiber,the structure and function of the pressure spring on the feeding plate are introduced,and the factors affecting its pressure are analyzed and tested.It is pointed out that the main factors affecting the spinning quality are rotor,false twister navel,carding roller,and the gripping force of feeding plate and feeding roller on sliver.The tests show that when the Saurer spinner is equipped,under the condition of the other dimensions of the pressure spring cannot be changed,the spring with the thickness of A＋0.20mm can produce the best gripping force on the sliver and can ensure that the sliver be evenly conveyed to the carding roller and fully carding,and the yarn quality can be improved by eliminating the unevenness and the thick and thin place caused by pressure problems.
Key Words:feeding plate;pressure spring;structure;gripping force;pressure;thickness
