Description

Screening plant is used in eiderdown processing

Technical Field

The invention relates to the technical field of down feather processing auxiliary devices, in particular to a screening device for down feather processing.

Background

The down feather is a reed-flower-shaped down feather growing on the abdomen of geese and ducks, as the down feather is an animal protein fiber, ten million triangular fine air holes are densely distributed on a spherical fiber of the down feather, the down feather can contract and expand along with the change of air temperature to generate a temperature adjusting function, and the down feather is higher than thermal insulation materials such as silk and cotton by one grade through analysis on filling power detection, for example, the 90-degree fluffy duck down feather with 450 degrees at the lowest standard is fluffy better than the silk and the cotton, so the down feather is only used as the thermal insulation material, and the economic value of the down feather is far higher than that of other thermal insulation materials.

At present, before down feather is processed, raw feather needs to be screened in advance according to types of feather flakes, feather filaments, down feather and the like, and the main principle is as follows: through stirring raw materials feather, make the feather divide out the hair piece through screening plant, then adopt air extraction equipment to take out flowers fine hair and broken hair, because the weight of flowers fine hair and broken hair is different, by the height difference that the wind blown, and then make both separate. The existing down feather screening device has the defects that the screening holes are blocked by down feathers or broken filaments, and broken pieces cannot be screened out, so that the screening effect is poor, the production efficiency is low, and the production cost is high.

Disclosure of Invention

The invention aims to provide a screening device for down feather processing, which solves the problems of poor screening effect, low production efficiency and high production cost caused by the fact that a screening hole is often blocked by down hairs or broken filaments and broken pieces cannot be screened out in the existing down feather screening device.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a screening device for down feather processing comprises a bottom plate and a screening box arranged on the bottom plate, wherein a feeding hole is formed above the screening box, a feather piece discharging hole is formed in the side wall of the screening box, a screening plate is movably arranged in the screening box, air blowers and C-shaped discharging pipelines are correspondingly arranged on the side walls of the two sides of the screening plate, openings at the two ends of each C-shaped discharging pipeline are connected with the screening box, and the screening plate is in sliding fit with a driving mechanism arranged on the inner wall of the screening box;

the screening box is characterized in that a screening net is obliquely arranged on the inner wall of the screening box and below the opening at the lower end of the C-shaped discharging pipeline, a down collecting box and a wool collecting box are correspondingly arranged below the screening net and at the bottom of the screening box, and a wool collecting box is arranged below the wool discharging port and on the bottom plate.

As a further improvement of the invention, the bottom of the screening plate is provided with a vibration motor, the periphery of the bottom of the screening plate is provided with shock absorption support legs, two shock absorption support legs on any side are hinged and installed on a supporting block protruding in the screening box, and two shock absorption support legs on the other side are in sliding fit with the driving mechanism through sliding guide pins.

As a further improvement of the invention, the driving mechanism comprises an air cylinder arranged on the inner wall of the screening box and an annular guide plate connected with the air cylinder, and the annular guide plate is in sliding fit with the screening plate.

As a further improvement of the invention, the mesh diameter of the screening net is larger than the diameter of the broken filaments, and the mesh diameter of the screening net is smaller than the diameter of the flosses.

The invention has the beneficial effects that:

compared with the prior art, the screening plate capable of vibrating up and down separates the wool chips, the wool yarns and the velvet according to different specific gravities among the wool chips, the wool yarns and the velvet, and then screens and divides the wool chips, the wool yarns and the velvet into a net, the wool yarns and the velvet are further separated according to different sizes and volumes of the wool yarns and the velvet, and the wool chips, the wool yarns and the velvet cannot be damaged in the whole screening process; the down feather screening device solves the problems that the existing down feather screening device often has down feather or broken filaments blocking screening holes, and broken pieces cannot be screened out, so that the screening effect is poor, the production efficiency is low, and the production cost is high. In addition, the invention has compact structure and strong operability.

As a further improvement of the invention, the diameter of the mesh of the screening net 7 is larger than that of the broken filaments, and the diameter of the mesh of the screening net 7 is smaller than that of the broken down flowers, so that when the mixture of the broken filaments and the broken down flowers falls onto the screening net 7 from the lower port of the C-shaped discharge pipeline 6, the broken filaments can be filtered and fall into the broken filament collecting box 10 on the right side, and the broken down flowers can continuously roll down into the broken down flower collecting box 9 on the left side from the screening net 7 according to the diameter of the mesh of the screening net 7.

The use method of the invention comprises the following steps:

firstly, raw down feather is poured onto a screening plate 3 from a feeding hole 2a, a vibration motor 4 is started, the raw down feather is separated and layered according to different specific gravities of feather pieces, feather filaments and down feather, the layered feather pieces are located at the lower layer position, the feather filaments and the down feather are located at the upper layer position, an air blower 5 is started to blow air, the mixture of the feather filaments and the down feather is blown into a C-shaped discharging pipeline 6, and the next step of screening is carried out;

the screened feather pieces are pulled by the cylinder 12 to enable the screening plate 3 to incline leftwards and slide into the feather piece collecting box 8 below after inclining to the position abutting against the feather piece discharging port 2 b;

and then, the mixture of the broken filaments and the broken down falls onto a sieving net 7 which is obliquely arranged from a lower port of a C-shaped discharge pipeline 6, and the broken down and the broken filaments are sieved according to the characteristic that the diameter of meshes of the sieving net 7 is smaller than that of the broken filaments and respectively falls into corresponding collecting boxes.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
