Description

Technical Field

[0001] This utility model relates to the field of down sorting, and in particular to a down-sorting device for a high-down machine. Background Technology

[0002] A down sorting machine, also known as a down feather separator or high-loft down separator, utilizes aerodynamic principles. A fan generates a stable airflow with specific speed and direction to separate down feathers of different qualities, cluster sizes, and loft. The different trajectories and suspension states of the down feathers under the influence of the airflow achieve the purpose of grading. The down sorting machine is a crucial piece of equipment in the feather processing workflow, characterized by high efficiency, automation, flexibility, and environmental friendliness. With continuous technological advancements and market development, down feather sorting machines will play an even more important role in the down processing industry.

[0003] High-quality down can be extracted using a high-quality down extractor for making down jackets, down comforters, and other down products. In the authorized Chinese utility model patent "Announcement No.: CN206474429U, Name: A Down Separating Machine", a secondary separating chamber is used to prevent unseparated down from being discarded. In the authorized Chinese utility model patent "Announcement No.: CN216323346U, Name: A High-Quality Down Separating Device with Automatically Controlled Airflow", a fan and ventilation pipe work in conjunction with a conveyor belt, and a metal rod works in conjunction with a conductive rod. This allows the fan to drive airflow, causing the air to blow through the conveyor belt and lift the feathers and down. Because down is lighter, it flies higher, making it easier to separate the down.

[0004] In order to ensure the separation effect of down, the two applications mentioned above have different approaches. One application has two separation chambers, but this increases the size of the equipment and makes the down separator occupy a larger area. The other application increases the air volume, which makes the down fly higher. However, the increase in air volume requires an increase in the power of the fan and the ventilation duct, which increases energy consumption and makes the operating cost of the down separator higher. In addition, the two applications have difficulty separating down into multiple stages for extraction, that is, it is difficult to collect down of different sizes separately. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art in which the separation of down increases the size of the equipment or the consumption of energy and is difficult to extract in multiple stages, and to provide a down separation device for a high-down machine.

[0059] The grading compartment module 13 is used to grade and extract down feathers of different sizes.

[0060] The grading compartment module 13 is divided into three, four, or five compartments in the vertical direction to achieve multi-level grading of down, that is, to extract down of different sizes by grading using the grading compartment module 13.

[0061] In use, the down is ventilated by the bottom support module 11 of the electronic control and air supply module 12, and the down is dispersed and lifted by the dispersing structure in the bottom support module 11. Then, the down is graded and extracted by the collection module 14 and the grading module 13.

[0062] When the grading compartment module 13 is a three-compartment unit, the high-down machine uses the principle of large air volume and low air pressure to process the raw down into compartments. The required down specifications and varieties are extracted by adjusting the air volume of the centrifuge and the distance between the internal partitions of the down separator. It is double-layered, with the bottom layer being an all-iron structure and the upper layers being a steel-wood structure and multi-layer plywood. It is equipped with an electrical control cabinet, an automatic down-adding machine, a vacuum bagging box, and a dust box.

[0071] In this technical solution, the rotary drive component 4 drives the rake blade 33 and other structures to rotate. The rake blade 33 can fan like a fan to generate wind, which is used to fan the feathers upward. That is, the rake blade 33 fans the feathers upward, thereby classifying and collecting the down. The down can be classified and collected well without increasing the power of the fan or the size of the equipment, resulting in a good down separation effect.

[0072] Multiple mounting posts 32 are arranged in a spiral structure on the surface of the rotating shaft 31.

[0073] In this technical solution, multiple mounting columns 32 can fully cover the space inside the bottom compartment 2.

[0074] The rake blade 33 has a rectangular sheet-like structure.

[0075] In this technical solution, the rake blade 33 can fan the down feathers upwards like a fan.

[0076] The mounting post 32 and the rotating shaft 31, and the rake blade 33 and the mounting post 32 are all detachably connected by bolts.

[0077] In this technical solution, the detachable design facilitates the inspection and maintenance of the fan assembly 3.

[0078] In use, the rotary drive assembly 4 can drive the rotary shaft 31 to rotate, which in turn drives the mounting column 32 to rotate, which in turn drives the rake blade 33 to rotate. The rotation of the rake blade 33 is used to fan the down upwards, and then the down is graded in the grading chamber module 13. The graded down is collected by the collection module 14.

[0079] Two symmetrically distributed transverse dispersing components 5 are provided above the fan assembly 3, and the two transverse dispersing components 5 are respectively connected to the rotation drive assembly 4.

[0080] The transverse dispersing component 5 includes a transverse rotating shaft 51.

[0086] One side of the drive sprocket 42 is connected to the output end of the drive source 44, which is connected to the inner wall of the drive housing 41.

[0087] In this technical solution, the rotary drive component 4 can simultaneously provide driving force for the fan assembly 3 and the lateral dispersion component 5.

[0088] In use, the drive source 44 can drive the corresponding drive sprocket 42 to rotate, which in turn drives the drive chain 43 to rotate, which in turn drives another drive sprocket 42 to rotate. When the two drive sprockets 42 rotate, they can respectively drive the rotating shaft 31 and the transverse rotating shaft 51 to rotate.

[0089] Multiple sets of longitudinal dispersing components 6 are arranged between the fan assembly 3 and the transverse dispersing assembly 5, and both ends of the multiple sets of longitudinal dispersing components 6 are respectively connected to the rotary power assembly 7.

The longitudinal dispersing blade 62 can disperse the down longitudinally. In conjunction with the transverse dispersing component 5, it can make more comprehensive contact with the down in the bottom compartment 2, so as to disperse the down and facilitate the lifting of the down.

[0094] The rotating power assembly 7 includes a power housing 71 connected to the outside of the bottom compartment 2. Two power sprockets 72 are symmetrically distributed on the left and right sides in the inner cavity of the power housing 71. The sides of the power sprockets 72 are meshed with the power chain 73.

Two transmission components 76 located on the same horizontal straight line are respectively connected to the two ends of the longitudinal rotating shaft 61.

[0098] In this technical solution, the rotating power component 7 can provide driving force to the longitudinal dispersing component 6 from both ends, so that multiple longitudinal dispersing components 6 can rotate synchronously and the rotation of the longitudinal dispersing component 6 is more stable.

[0099] In use, the power source 74 drives the corresponding power sprocket 72 to rotate, which in turn drives the power chain 73 to rotate.
