A screening device for down processing

Abstract

The invention relates to the technical field of feather and down processing auxiliary devices, in particular to a screening device for down processing, which includes a base plate and a screening box arranged on the bottom plate, a feed inlet is arranged above the screening box, and the screening box A flake discharge port is provided on the side wall of the screen, and a screening plate is movable inside the screening box, and a blower and a C-shaped discharge pipe are correspondingly provided on the side walls of the screening plate. The plate is slidably matched with the driving mechanism arranged on the inner wall of the screening box; a screening net is arranged obliquely below the C-shaped discharge pipe, and a velvet collection box and a hair collection box are correspondingly provided under the screening net. , a wool collection box is arranged below the wool outlet. The invention solves the problems that the existing down screening devices often have the problems that the screening holes are blocked by fluff or filaments, and the flakes cannot be screened out, resulting in poor screening effect, low production efficiency and high production cost. In addition, the invention has compact structure and strong operability.

Description

technical field [0001] The invention relates to the technical field of down processing auxiliary devices, in particular to a screening device for down processing. Background technique [0002] Down is the flower-like fluff that grows on the abdomen of geese and ducks. Since down is a kind of animal protein fiber, its spherical fibers are densely covered with tens of thousands of small triangular pores, which can shrink and expand as the temperature changes, resulting in air conditioning. The temperature function, from the analysis of the bulkiness test, down is a level higher than silk, cotton and other thermal insulation materials, such as the minimum standard of 450 degrees fluffy 90 duck down is also more fluffy than silk and cotton, so down is purely used as a thermal insulation material Material, its economic value is much higher than other thermal insulation materials. [0003] At present, before processing down feathers, it is necessary to use screening equipment to ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a screening device for down processing to solve the problem that the existing down screening device often has down or hairs blocking the screening holes, and the raw flakes cannot be screened out, resulting in poor screening effect and low production efficiency. The problem of low efficiency and high production cost
