Down selection machine

Abstract

The invention belongs to the field of down feather deep processing equipment and particularly relates to a down feather sorter which comprises a down feather box and a drum sieve part fixedly connected with the interior of the down feather box, wherein the inner cavity of the drum sieve part is communicated with a feed opening so as to form a feeding cavity; the feeding cavity is communicated with an external large down feather collecting component by virtue of a discharging pipeline; a small down feather cavity is formed in a region between the outer wall of the drum sieve part and the inner wall of the down feather box and is connected with an external small down feather collecting component by virtue of a material conveying pipeline; the feeding pipeline and the material conveying pipeline are internally provided with negative-pressure environments which are correspondingly communicated with the feeding cavity and the small down feather cavity; the small down feather cavity and the feeding cavity are communicated with each other by virtue of sieve holes; the feeding cavity is internally provided with a stirring part; the bottom end surface of the drum sieve part is of an inclined surface or cambered surface structure, and the lowest part of the bottom end surface of the inclined surface or cambered surface structure is provided with a collecting groove used for accommodating sandstone impurities. The down feather sorter is capable of effectively ensuring high efficiency in down feather sorting and ensuring the high down feather sorting quality, and is reliable and stable in operation.

Description

Technical field [0001] The invention belongs to the field of down deep processing equipment, and specifically relates to a down-and-down flower selection machine. Background technique [0002] The raw material for down processing mainly comes from duck and goose feather down; because of its soft warmth, breathability and cold resistance, and heat dissipation and other excellent properties, it is the best filler for making warm products. At present, the down content of down products on the market is mostly 70% to 90%. Originally, the down products were mainly manufactured through the process of washing down. For example, it is described in the Chinese patent application with the publication number CN101670340 titled "Separation Process of Goose Feather and Down", that is, through washing, drying and sieving to achieve the purpose of selecting down and obtaining a higher quality designation Down size of down; due to the limitations of traditional washing and selection, it is often...

AI Technical Summary

Problems solved by technology

However, the above-mentioned method still has the following defects: on the one hand, the thick down as raw material, due to the differences in the slaughtering environment of ducks and geese and even the transportation environment, there are not only the above-mentioned neck hair pieces, wool piece silk, fluff silk and immature small down Flowers, etc. need to be separated, and there are often fine debris such as sand and even rubble; in the current selection operation process, it is still difficult to have an effective fine-grained treatment method for the above-mentioned debris; often or due to small particles of sand Impurities such as other impurities fall directly into the small velvet collection tank along the sieve hole, which brings difficulties to the subsequent small velvet treatment process; or because the sundries directly enter the large velvet collection cabinet, which affects the post-processing of the large velvet

On the other hand, the current above-mentioned selected equipment often needs to use multiple fans to cooperate with each other according to the volume of the equipment, so as to achieve the effect of its negative pressure suction velvet. The facility cost is high and the structure is relatively complicated. It has a greater impact on the actual production efficiency of the manufacturer

In addition, the integral design structure of the traditional trommel screen is not easy to carry, maintain and replace. As a moving part, the huge trommel screen is often damaged due to factors such as its own weight, and because it is an integral part, damage to part of the structure is often With the update of the overall components, the maintenance cost is large and the cycle is long
