A seed cotton foreign fiber cleaning machine

Abstract

The invention discloses a cotton foreign fiber cleaning machine, which comprises a soft impurity removal channel arranged vertically below the cotton inlet, and a first boiling cleaning area for cleaning small foreign fibers is arranged under the soft impurity removal channel. The left side of the boiling cleaning area is provided with a second boiling cleaning area; the invention adopts the soft miscellaneous knife to automatically cut off the long foreign fibers wound on the soft miscellaneous roller under the action of the mechanical force of the knife, and discharge them out of the machine at the same time. First of all, the long foreign fibers are removed to avoid the more trivial foreign fibers that are difficult to remove in the subsequent blows. This process does not require parking or manual removal, which saves manpower; the long, soft and miscellaneous seed cotton after cleaning is further After being loosened and impurity removed, it enters two boiling cleaning areas continuously. Under the action of the wind force of the high-speed stripping roller and the wind force provided by the external fan, the state of the seed cotton in the two boxes is similar to "boiling". At this time, the fine The foreign fiber floats on the upper part and is adsorbed on the dust cage by the negative pressure of the dust cage and discharged from the machine.

Description

technical field [0001] The invention relates to the technical field of cotton blending processing equipment, in particular to a seed cotton foreign fiber cleaning machine. Background technique [0002] The problem of "foreign fiber" is the most prominent problem affecting the quality of my country's cotton and restricting the market competitiveness of my country's cotton and cotton textiles in recent years. Over the years, due to the existence of foreign fibers in cotton, the competitiveness of domestic cotton and cotton fabrics in the international market has been weakened, causing cotton and cotton spinning enterprises to invest a lot of manpower and material resources in picking. my country's climatic conditions determine that mulch must be used in the planting stage for a foreseeable long time. Especially in machine-picked cotton, the mulch enters the seed cotton during harvesting, shipping and other processes, and after being hit by processing equipment, it becomes a l...
