Abstract
An apparatus for cleaning trash from cotton lint utilizes a combing cylinder having a plurality of teeth covering its surface and extending therefrom in a manner to release the cotton lint to a cleaning cylinder. The combing cylinder surface moves slower than the cleaning cylinder to comb the lint as it is delivered to the cleaning cylinder. Means are provided to vary the speed of the combing cylinder to match the lint processing parameters, including negating lint combing all together.
Claims21
An apparatus for cleaning and combing lint cotton entering the apparatus in an airstream commingled with foreign matter, comprising a combing cylinder closely adjacent a cleaning cylinder said combing cylinder covered with sharp pointed, closely spaced teeth with a draft side thereof extending substantially radially from said combing cylinder, said cleaning cylinder and said combing cylinder each mounted for rotation about parallel axes such that the proximal surfaces of said combing cylinder and said cleaning cylinder move in the same direction with the surface of said cleaning cylinder moving faster than an adjacent surface of said combing cylinder, said combing cylinder positioned to remove lint cotton from said airstream and to deliver said removed lint cotton to said cleaning cylinder and provide a combing action to said cotton as it passes between said combing and cleaning cylinders.
An Apparatus for cleaning and combing lint cotton entering the apparatus in an airstream commingled with foreign matter, comprising a combing cylinder closely adjacent a cleaning cylinder said combing cylinder covered with sharp pointed, closely spaced teeth with a draft side thereof extending substantially radially from said combing cylinder, said cleaning cylinder and said combing cylinder each mounted for rotation about parallel axes such that the proximal surfaces of said combing cylinder and said cleaning cylinder move in the same direction with the surface of said cleaning cylinder moving faster than an adjacent surface of said combing cylinder, said combing cylinder positioned to deliver lint cotton from said airstream to said cleaning cylinder and provide a combing action to said cotton as it passes between said combing and cleaning cylinders,
- a variable speed drive connected to said combing cylinder to rotate said cylinder at a rate which is variable with one or more selected ginning parameters, and,
- further comprising a gin feeder feed roll speed detector operably connected control said variable speed drive for said combing cylinder.
An Apparatus for cleaning and combing lint cotton entering the apparatus in an airstream commingled with foreign matter, comprising a combing cylinder closely adjacent a cleaning cylinder said combing cylinder covered with sharp pointed, closely spaced teeth with a draft side thereof extending substantially radially from said combing cylinder, said cleaning cylinder and said combing cylinder each mounted for rotation about parallel axes such that the proximal surfaces of said combing cylinder and said cleaning cylinder move in the same direction with the surface of said cleaning cylinder moving faster than an adjacent surface of said combing cylinder, said combing cylinder positioned to deliver lint cotton from said airstream to said cleaning cylinder and provide a combing action to said cotton as it passes between said combing and cleaning cylinders,
- a variable speed drive connected to said combing cylinder to rotate said cylinder at a rate which is variable with one or more selected ginning parameters,
- wherein said variable speed drive comprises a separate V- belt drive to the combing cylinder incorporating a mechanical variable pitch diameter sheave.
An Apparatus for cleaning and combing lint cotton entering the apparatus in an airstream commingled with foreign matter, comprising a combing cylinder closely adjacent a cleaning cylinder said combing cylinder covered with sharp pointed, closely spaced teeth with a draft side thereof extending substantially radially from said combing cylinder, said cleaning cylinder and said combing cylinder each mounted for rotation about parallel axes such that the proximal surfaces of said combing cylinder and said cleaning cylinder move in the same direction with the surface of said cleaning cylinder moving faster than an adjacent surface of said combing cylinder, said combing cylinder positioned to deliver lint cotton from said airstream to said cleaning cylinder and provide a combing action to said cotton as it passes between said combing and cleaning cylinders,
- a variable speed drive connected to said combing cylinder to rotate said cylinder at a rate which is variable with one or more selected ginning parameters, and
- further comprising an air separator positioned in said air stream upstream of said combing cylinder to divert substantially all of the air in said air stream away from said combing cylinder and any lint carried on said combing cylinder.
An apparatus for cleaning and combing lint cotton entering the apparatus in an air stream commingled with foreign matter, comprising a combing cylinder closely adjacent a cleaning cylinder each mounted for rotation about parallel axes such that proximal surfaces of said combing cylinder and said cleaning cylinder move in the same direction, with the surface of said cleaning cylinder moving faster than the surface of said combing cylinder, a variable speed drive connected to said combing cylinder to rotate said cylinder at a rate variable with one or more selected ginning parameters, said combing cylinder positioned to remove lint cotton from said airstream and to deliver said removed lint cotton to said cleaning cylinder and provide a combing action to said cotton as it passes between said cylinders.
An apparatus for cleaning and combing lint cotton entering the apparatus in an air stream commingled with foreign matter, comprising a combing cylinder closely adjacent a cleaning cylinder each mounted for rotation about parallel axes such that proximal surfaces of said combing cylinder and said cleaning cylinder move in the same direction, with the surface of said cleaning cylinder moving faster than the surface of said combing cylinder, a variable speed drive connected to said combing cylinder to rotate said cylinder at a rate variable with one or more selected ginning parameters, said combing cylinder positioned to deliver lint cotton from said airstream to said cleaning cylinder and provide a combing action to said cotton as it passes between said cylinders, further comprising one or more control sensors operably positioned to monitor lint moisture, lint color, lint trash content, lint grade, or lint throughput with said control sensors having an output to a speed control circuit for responsively varying the speed of said combing cylinder.
