Description

The different fine descaling machine of a kind of unginned cotton
Technical field
The present invention relates to a kind of descaling machine, particularly about a kind of different fine descaling machine of unginned cotton that is used for clearing up all kinds of different fibres of unginned cotton.
Background technology
All kinds of different fine problem in the cotton is a puzzlement cotton spinning industry hard nut to crack for many years, and removing different fibre at present has dual mode: 1, hand picking mainly is that people clear up different fibre before unginned cotton processing or before the opening and cleaning step.And hand picking efficient is low, and the cost height is selected effect and influenced greatly by subjective factor.2, equipment cleaning, cleaning equipment mainly contain different fine cleaning equipment of unginned cotton and the different fine cleaning equipment of gined cotton.The different fine cleaning equipment of existing in the market unginned cotton mostly uses machinery to twine and wind-force is cleaned combinatorial principle, and it mainly is to rely on the fast rotational of winding roller to twine the different fibre of strip that machinery twines, and then the different fibre that is wound is cleared up; The wind-force that wind-force is cleaned the common centrifugal blower of main dependence is cleared up the big different fibre of floating velocity and unginned cotton difference.There is following problem in the existing different fine cleaning equipment of unginned cotton: 1, winding roller can not in time be cleared up after twining and expiring, and must shut down during cleaning, and cleaning efficiency is low continuously.2, can't clear up with block different fibres such as the cloth of different fine adhesion, the disconnected ropes made of hemp.3, wind-force is cleaned owing to lack the unginned cotton fibre-opening unit having, makes fully shredding of unginned cotton, so has influenced the cleaning effect of the big different fibre (as mulch film fragment, feather, hair etc.) of floating velocity and unginned cotton difference.4, existing equipment adopts common centrifugal blower air draught, needs parts such as big dust cage, and the fan operation resistance is big, can't guarantee that unginned cotton layer width total length direction air-flow is even, influences the whole cleaning effect of different fibre.5, the existing equipment functional module is few, can't regulate the wind-force size, and the machine that can't guarantee is simultaneously adopted different fine cleaning effect cotton and hand picked cotton, and is also poor to the adaptability of output simultaneously.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of unginned cotton and hand can descaling machine adopted and pluck all kinds of different fibre in the unginned cotton, and cleaning efficiency height, the different fine descaling machine of unginned cotton that cleaning effect is good.
For achieving the above object, the present invention takes following technical scheme: the different fine descaling machine of a kind of unginned cotton, and it is characterized in that: it comprises a casing, is provided with in the described casing and twines cleaning plant, colludes and draw defecation cleaning plant, boiling fibre-opening unit having and wind-force cleaning plant; Described winding cleaning plant comprises two hello flower rollers that are arranged on the casing porch, and two described belows of feeding the flower rollers are provided with and are divided into two groups of winding rollers that two passages are arranged, and the passage boundary of two groups of described winding rollers is provided with an adjustable plate; The described at least one tooth bar roller that draws the defecation cleaning plant to comprise to be successively set on described winding roller below that colludes, one auger and a doffing roller, described auger is positioned at the below of described tooth bar roller, the outlet of described auger is arranged on described casing one side, described doffing roller is positioned at the oblique below of described tooth bar roller, passage between described winding roller and the described tooth bar roller is provided with drain cotton plate, is provided with on the passage between described tooth bar roller and the described auger and drops down assorted plate; Described boiling fibre-opening unit having comprises the row's opening roller that is arranged on described doffing roller rear, described opening roller below is provided with the bellows of a connection blower fan, the top of described bellows is provided with some slit-aperture type tuyeres, and each described slit-aperture type tuyere is between any two adjacent described opening rollers; Described wind-force cleaning plant comprises the gettering cover of a connection blower fan that is arranged on described opening roller top.
One tooth bar roller is set between described tooth bar roller and described auger again, and the passage between two described tooth bar rollers is provided with and drops down assorted plate.
On the casing of described tooth bar roller circumferencial direction, be respectively arranged with some spaced impurities removal rods.
The blower fan that connects described bellows all is frequency conversion fans with the blower fan that is connected described gettering cover.
The present invention is owing to take above technical scheme, it has the following advantages: 1, winding cleaning plant of the present invention is owing to adopted novel two group winding rollers of timing automatic alternate run, replaced existing single group winding roller, therefore solved the problem that in time to clear up after winding roller twines completely preferably, and cleaning the time do not need to stop, and makes the different fine cleaning efficiency height of strip.2, of the present invention colluding draws the defecation cleaning plant owing to adopted parts such as tooth bar roller, doffing roller, thereby realized the cleaning of block different fibres such as cloth that miscellaneous equipment can't finish, the rope made of hemp.3, the present invention makes and the abundant shredding of unginned cotton under the pressure-vaccum synergy of blower fan group, has greatly improved the cleaning effect of the different fibre of mulch film, feather and hair class (floating velocity and unginned cotton difference are big) owing to adopted boiling shredding and wind-force to clean combined unit.4, the present invention is owing to adopt the adjustable parts such as slit-aperture type tuyere, gettering cover and blower fan group of wind-force, not only effectively guaranteed the different fine cleaning effect under all even different output of unginned cotton layer width total length direction air-flow, and the fan operation resistance is little, and device structure is simple.5, innovative design of the present invention combined type cleaning pattern, four kinds of cleaning modules are organically blended is one, has guaranteed the whole cleaning effect of the different fibre of unginned cotton.Unginned cotton cleaning effect of the present invention is good, different fine cleaning efficiency has improved 10%~20% than existing equipment, and it can be widely used in the cotton source mill cleaning to all kinds of different fibres in the unginned cotton (as various woven bag silks, cloth, cloth, mulch film, feather, people and animals' hair etc.).
