Corium fine hair wafts and selects device
Technical field
The utility model relates to a kind of villus fiber screening installation, specifically is that the skin fine hair that be equipped with to use on the artificial leather transfer flocking production line wafts and selects device.
Background technology
Artificial leather is the new product that occurs in recent years; Its outward appearance and feel and real leather-like are seemingly; Because surface layer adopts the double-layer fur surfacing process, can produce various true dermatoglyphs; Bottom is then taked the corium fabric flocking, and flocking is dry after beating and sanded treatment make it all being in close proximity to natural corium leather on the sense organ, on the feel, on the fastness, becomes genuine dermatine.
The transfer flocking technology of applicant's invention has been used on the artificial leather producing line, successfully produces artificial leather, and has obtained national inventing patent (patent No. 200610051931.X).For High-efficient Production high-quality artificial leather, artificial leather producing line need dispose the preceding road equipment that can screen high-quality corium fabric fine hair; And, when this equipment should guarantee that the artificial leather production equipment is produced continuously to the needs of high-quality corium fabric fine hair output, again can be in screening process get rid of impurity such as the caking raw material in the skin fine hair and sandstone, iron filings clean, obtain high-quality corium fabric fine hair and be used for transfer flocking, also just become the important goal in the equipment design.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that exist in the background technology, and a kind of optional equipment that wafts of guaranteeing skin fine hair quality is provided, and this equipment should have the characteristics that can remove impurity, can be continuously produced, and rational in infrastructure, and manufacture difficulty is little.
The technical scheme that the utility model proposes is: corium fine hair wafts and selects device, it is characterized in that this wafts to select device to comprise that wafing of vertically arranging selects case, the corium fabric fine hair that adds is progressively transported to the control amount feeder of disperser and the disperser that corium fabric fine hair is carried out transporting to after the dispersion treatment suede case that wafts; The described top outlet of selecting case of wafing communicates with the suede portion of wafing in the dermatine flocking thread by pipeline, and the bottom of selecting case of wafing is installed with the throwing suede device that is driven by actuating unit, and the rotation of the rotating vane of throwing suede device is perpendicular to ground; The output of described disperser selects the import of case side to communicate with wafing.
Described disperser is a worm gear prismatic blade disperser, exports and waft to select the feeding inlet of case end face, and import communicates with the delivery outlet of control amount feeder.
The cagem type feeder of horizontal layout is housed in the described control amount feeder, and loading hopper is installed in the top of control amount feeder.
The wormwheel blade axial end of described disperser is also connected surplus suede recovery channel, the unnecessary fine hair of flocking is returned again waft choosing to be used.
Operation principle of the present utility model is: corium fabric fine hair enters the back and parks in control amount feeder 2 temporarily from loading hopper 1, progresses into disperser 4 afterwards under the promotion of the screw blade of the cagem type feeder 3 of slow rotation; The blade that enters the corium fabric tomentum high speed rotating of disperser impacts and disperses (especially pressurized becomes crumby corium fabric tomentum to draw loose opening effectively), and entering immediately wafts selects case 15; Rotate with certain speed under the driving of actuating unit owing to throw the blade 12 of suede device, the thrust that is produced makes the corium fabric fine hair of throwing in the suede device become suspended state; The suede case bottom 8 so the fiber block group that is mingled in sandstone, the iron filings in the corium fabric fine hair and does not break up wafts because of proportion sinks to more gradually, and the comparatively sufficient high-quality corium fabric fine hair of dispersion, move upward because of proportion is gently suspending, carried by air-flow then and transporting to the suede case that wafts in the dermatine flocking thread cloth that wafts by pipeline 16 and carry out the flocking operation; Finish whole wafing and selected process.
The beneficial effects of the utility model are: since designed mechanism with feeding, disperse and the choosing of wafing organically combines, sandstone in the raw material, iron filings and the screening timely and effectively of the fiber block of not breaing up group not only can be rejected, guarantee the application of quality raw materials and the quality of dermatine; And can one continuous line work continuously, can successfully be matched in artificial leather producing line, the automation of production overall process is achieved.In addition, designed mechanism structure is simple and practical, and manufacturing cost is not high, helps applying.

The specific embodiment
Purpose of design of the present utility model is mainly used in the fluffy dispersion of corner zero material of animal hide, thus the clean fine hair of the choosing of wafing, collection free from admixture, nothing caking shape, no sandstone, no iron filings; Guarantee the product quality of artificial leather with this.
For this reason, the corium fine hair that provides of the present utility model wafts and selects device (as shown in the figure), comprises that wafing of vertically arranging selects case 15, corium fabric fine hair to be transported to disperser 5 by control amount feeder 2; The described top outlet of selecting case of wafing communicates with the suede case that wafts in the dermatine flocking thread by pipeline 16, the waft bottom of selecting case is installed with the throwing suede device (showing it is that motor 11 is by the rotation of belt wheel 10 driven vane axles among the figure) that has rotatable blade 12 and driven by actuating unit, and the rotation of blade is perpendicular to ground.
Described disperser 5 is turbo blade dispersers, and the charging aperture that is arranged on the turbo blade axial end communicates by the delivery outlet of pipeline 4 with control amount feeder 2; The output of disperser communicates with the import 7 of selecting the case side of wafing.
The cagem type feeder 3 of horizontal layout is housed in the described control amount feeder, and feeding quantity can be adjusted (the drive motors 3-1 that has shown feeder among the figure) by the rotating speed of regulating the cagem type feeder.Loading hopper 1 is installed in the top of control amount feeder 2.
The turbo blade axial end of described disperser is also connected surplus suede recovery channel 6; The fine hair that reclaims in the flocking production process enters disperser from surplus suede recovery channel 6.
Above-described cagem type feeder 3, turbo blade disperser and throwing suede device are conventional equipment, directly outsourcing or self-control.
