RAW COTTON MIXING MACHINE

PURPOSE:To prevent catching of raw cotton to a damper body by forming the damper body with a plate member capable of changing pathway of raw cotton to cotton feeding chamber side directly under the damper and cotton feeding chamber side on the downstream side and having a specific shape. CONSTITUTION:A damper body 6 of damper capable of changing to cotton feeding chamber side situated at downstream side of pathway of raw cotton and cotton feeding chamber 2 side directly under the damper with a plate member having circular cross section. A shaft for supporting the rotation of the damper projected on the outside of pathway of the raw cotton 3 is eccentrically coupled to the tip of piston rod 9b of fluid pressure cylinder device 9 arranged on the outside of the pathway and the damper body is kept so as to completely sink on the inside of raw cotton intake port 7 of cotton feeding chamber when the cotton feeding chamber is closed.
