Cotton feeding mechanism of cotton feeding device

A cotton feeding mechanism of a cotton feeding device relates to the field of cotton feeding process of pre-oxidation production lines in chemical fiber industry. A horizontal side of an upper press roller is connected with a conveying assembly, two axial sides of the upper press roller and a feeding upper roller are connected with a floating assembly, the floating assembly is screwed with the upper press roller through a spring seat, the axial top end of the upper press roller is connected with a motor through a shaft, and a motor counterweight is mounted on the opposite side of the motor. The floating assembly is in threaded connection with the floating roller through a spring seat, a bearing is arranged below the spring seat, the bearing rotates but the spring seat does not rotate, and the floating assembly moves up and down along with rotation of the upper pressing roller, so that the phenomenon that the cotton opening roller is damaged due to the fact that a conveying belt runs for a long time is avoided
