Abstract
Description
Technical Field
[0001] This utility model relates to the field of down feather shaft separation technology, and in particular to a down feather shaft separation device. Background Technology
[0002] Down is a high-quality insulating filling material widely used in home textiles and clothing products such as down jackets and down comforters. During the processing of down, a large number of feather shafts, dust, and other impurities are mixed in with the raw down feathers. If these are not effectively separated, they will seriously affect the quality and warmth retention of the down. Currently, most down and feather shaft separation equipment on the market uses a single screening or air separation method. With a single screening method, it's difficult to achieve complete separation because down fibers and fine feather shafts are similar in size, and the screening mesh is prone to clogging, affecting separation efficiency. With a single air separation method, the air velocity is difficult to control precisely; excessive air velocity can cause down fiber loss, while insufficient air velocity cannot effectively separate feather shafts, and there is also the problem of low purity in the separation of down and feather shafts. Furthermore, some separation equipment has an unreasonable feeding and conveying structure design, which can easily cause tearing damage to down fibers during conveying, reducing the usability of the down. Therefore, there is a need to propose a down and feather shaft separation device. Utility Model Content
[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a down feather shaft separation device.
[0004] The technical solution of this utility model: A down feather shaft separation device includes a pre-dispersion mechanism, a slow conveying mechanism, a screening mechanism, and an air separation mechanism.

A separation plate is slidably installed inside each separation chamber. A negative pressure discharge pipe is installed on the rear side of each air separation box corresponding to the position of each separation chamber. A cleaning window is rotatably installed on the front side of each air separation box corresponding to the position of each separation chamber.

[0006] Preferably, the dispersion box is provided with a support inside, the top surface of the support has a groove, the inside of the groove is provided with a bearing, and the bottom end of the stirring shaft is slidably connected to the bearing.
[0007] Preferably, the bottom end of the dispersion box is provided with a connecting pipe, and the bottom end of the connecting pipe is fixedly connected to the top of the conveying cylinder.

The trapezoidal blocks are slidably connected to the trapezoidal grooves, and the separation holes on the three separation plates gradually decrease in size from top to bottom.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: This invention features a dual separation structure consisting of a screening mechanism and an air separation mechanism. The multi-layered sieve plate of the screening mechanism enables graded screening of raw down feathers, first separating most of the feather shafts of different sizes. The air separation mechanism further separates fine impurities and residual feather shafts, significantly improving the separation purity and efficiency of the down feathers, thus solving the problem of poor separation effect in existing equipment. By setting a slow conveying mechanism, the raw down feathers are prevented from directly passing through the air separation mechanism, thus avoiding fiber damage and ensuring the integrity of the down feathers. This solves the problem of easy damage to down fibers in existing equipment. The air separation mechanism is equipped with three wind speed adjustments, which can be precisely adjusted according to actual processing needs to avoid excessive wind speed causing down loss or insufficient wind speed affecting the separation effect, thereby improving the adaptability of the equipment.
