Technical Field

The invention belongs to the field of textile materials and technologies, and relates to a device and a method for preparing a down uniformly-distributed fiber net.

Background

The down is widely applied to the fields of heat insulation and warm keeping of clothes, bedding and the like, has a fractal dimension of about 1.7, and is the lightest natural warm keeping material under the condition of having the same warm keeping effect. The down feather core, down feather branches, down feather small branches and triangular and forked nodes of the down feather form a special spatial multi-stage branched structure, so that the down feather aggregate can store a large amount of static air, hinder heat transfer and form an excellent heat insulation layer. Due to the special space structure of the down feather, the down feather has the advantages of light weight, softness, fluffiness, warmth retention and the like, the processing and the utilization of the down feather are limited due to the structural particularity, particularly the down feather is uniformly laid, and the damage or low damage to the down feather is ensured while the down feather is processed. At present, specialized lapping equipment aiming at uniform distribution of down feather is not seen.

The method is characterized in that a single-layer fiber net of the down feather is prepared by controlling the size and the rotating speed of a V-shaped groove in a cylinder, although the distribution of the down feather in the prepared single-layer fiber net has certain uniformity, the down feather amount is difficult to accurately control, the thickness of the fiber net is uneven, and a bare leakage point without the down feather exists at the joint of the V-shaped groove; the Du Zhao group conveys down feather with set thickness and square meter quality to a homogenizing mechanism through the homogenizing mechanism, quantitative feeding of the down feather is controlled through multi-level dithering, the uniformity of a single-layer down feather fiber net is improved to a certain extent, and quantification of the down feather is emphasized to be fed (Du Zhao group, a forming device and a method for quantitative feeding of the down feather, the application number is 201010174929.8, and the application publication number is CN 101831730A); the Kangkaiwen implants the down feather in the middle of the double-layer cloth to improve the efficiency of fixing the down feather, and hardly relates to the problem of down feather lapping uniformity (the Kangkaiwen, a down feather lapping machine, a national invention patent, application No. 201910055129.5, application publication No. CN 109730385A); guijie made the density of down uniform by a down-laying device and reciprocating motion, but the device was complex (Guijie, a down-laying device, application No. 201710345588.8, No. CN 107098307A); ronie Reuben, which is less concerned with the problem of web uniformity by mixing down, feathers and binder fibers and then dropping them directly onto a conveyor belt (U.S. Pat. No. 5, 20190283078, 1); however, these methods do not pay special attention to the problem of preparing a down fiber net with uniform distribution and a quasi-single-layer down fiber net, and the control of the down body to prepare the down fiber net with uniform distribution has important significance for the down industry and the textile industry.

Sorting down heterochromatic down: goose down is fed from a feeding port of a dispersing mechanism (1), a first motor (116) and a second motor (124) of the dispersing mechanism (1) are started to drive an upper dispersing roller (113) and a lower dispersing roller (121) to rotate so as to drive the other dispersing rollers, the rotating speed of the upper dispersing roller is controlled to be 80 revolutions per minute, the rotating speed of the lower dispersing roller is controlled to be 110 revolutions per minute, the goose down is dispersed under the action of a plurality of dispersing rollers, then the goose down enters a down storage mechanism (2), a photoelectric sensor (22) is started, a third motor (32) of a lapping mechanism (1) is started to drive a down outlet roller (31) to rotate, the rotating speed of the motor is adjusted so that the rotating speed of the down outlet roller (31) is 100 revolutions per minute, the down outlet roller (31) controls the falling quantity and volume of the goose down, and then a goose down fiber net with the natural thickness of 3.0cm is prepared under the action of two baffles (35) on the upper box surface of a goose down channel (34), the goose down is evenly distributed on the fiber net. And entering a next procedure, detecting and judging whether the different-color goose down exists or not through camera shooting, and correspondingly controlling the down grabbing mechanism to grab the different-color goose down.
