Describe Swing Door Mechanism In Bale Opener

Object: To study the swing door mechanism in bale opener

Description: swing door situated along the width of the machine, bale opener.it is attached with the fulcrum to the lever which carries the dead weight that can

be moved over the length of lever for adjusting the hopper capacity.

This lever is connected with a connecting rod which again connect to a lever. This lever contain the belt which is responsible for the motion extended feed lattice and so for the supply of cotton.

Working: The cotton existing on hopper feed lattice exerts some force on swing door this force is counter balanced by torque due to dead weight but when cotton inside increases to a great extent and the force exerted by cotton is not counter v balanced by the torque due to dead weight then lever moves up to maintain equilibrium this moves connecting rod in upward direction which causes to slackening of belt and hence power transmission to the feed lattice collapse and consequently the supply stops but as soon as cotton inside hopper decreases upto certain level lever moves down resulting in tightening of belt and hence rebuilding power supply so feed again starts.
