Abstract
Description
Technical Field
[0001] This invention relates to the field of down sorting technology, specifically a down single-item sorting machine and its usage method. Background Technology
[0002] Down sorting machines typically include a housing, a dust screening unit, a power unit, a sorting unit, and a receiving unit. Utilizing aerodynamic principles, a fan separates the down raw materials from feathers to obtain individual down products, while also filtering out impurities such as stiff feathers and long feathers. In this process, down is the primary target of sorting; however, the following problems exist in actual operation: (1) Existing down single-item sorting machines drive the down mixture to rotate rapidly by centrifugal rotation, so that the down is quickly separated from the internal impurities, which is convenient for subsequent sorting. However, during the high-speed rotation of the down, some large impurities will block the screen holes under the action of centrifugal force, resulting in poor down passability and affecting the overall sorting effect. (2) Down is subjected to strong centrifugal force during high-speed rotation. The different densities of the various components of down cause it to stratify. The heavier hard feathers and long feathers are distributed on the outer side of the filter barrel, while the lighter down accumulates in the center of the filter barrel, resulting in poor down passage and low overall sorting efficiency.
[0003] To address these issues, the present invention provides a down-filled single-item sorting machine and its usage method. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a down-filled single-item sorting machine and its usage method, thus solving the aforementioned problems.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a down single-item sorting machine, which can filter large volume impurities such as hard feathers and long feathers contained in the down raw materials, and can prevent impurities from accumulating and clogging, thereby improving the overall impurity removal and sorting effect, including a sorting tank, a screening barrel located inside the sorting tank, a power unit located above the sorting tank, a lifting component located on one side of the sorting tank, and a collection component located below the sorting tank, and also includes a separation component for sorting down and filtering large volume impurities in the down; The screening barrel includes several screening chambers arranged radially, and the diameter of the screen holes in the screening chambers decreases gradually from the inside to the outside. The separation assembly includes a stirring paddle located in the central screening chamber for rotating to push down feathers. A scraper is provided at the end of the stirring paddle for scraping off down feathers adhering to the screen holes. The stirring paddle moves up and down along the axis of the screening barrel during rotation.
[0006] Preferably, the separation assembly further includes a bracket fixedly connected inside the sorting tank, the bracket having an internally threaded sleeve through it, and a reciprocating screw threaded through the internally threaded sleeve, the top end of the reciprocating screw extending movably into the screening tank.
[0007] Preferably, the sorting tank is provided with a first driving assembly for driving the screening barrel to rotate. The first driving assembly includes a second bracket that is rotatably sleeved on the outside of the internal threaded sleeve. A third bracket is welded to the bottom of the sorting tank. A driving device is provided on the third bracket. A transmission shaft is provided on the output shaft of the driving device. A gear set one that drives each other is provided on the transmission shaft and the bottom of the second bracket.
[0008] Preferably, the sorting tank is provided with a second drive assembly for driving the separation assembly. The second drive assembly includes a driven intermittent gear disposed at the bottom end of a reciprocating screw. A linkage shaft is rotatably connected to the support three. An active intermittent gear is disposed on the linkage shaft. A gear set two that drives each other is disposed on the linkage shaft and the transmission shaft.
[0009] Preferably, the screening barrel is detachably equipped with a sealing component.
[0010] Preferably, the lifting assembly includes a telescopic component, the fixed end of which is connected to the outer wall of the sorting tank, and a bracket is welded to the outer wall of the enclosed cover, the bracket being connected to the telescopic end of the telescopic component.
[0011] Preferably, the collection assembly includes a collection box disposed at the bottom of the sorting tank, the outside of the collection box is provided with a dust filter screen, and the outside of the collection box is provided with a box door.
[0012] The present invention also provides a method for using a down feather single-item sorting machine, comprising the following steps: S1: The lifting component lifts the power unit to load the down raw material into the innermost screening chamber of the screening barrel, and then the lifting component is reset. S2: The power unit performs air separation on the down inside the screening barrel. At the same time, the first drive component and the second drive component drive the screening barrel and the separation component to work, so that the stirring paddle and scraper stir the down and separate the down from impurities, while avoiding the screen holes on the innermost barrel of the screening barrel from being blocked. Large impurities in the down are filtered into the innermost screening chamber of the screening barrel. Meanwhile, different components in the down enter the screening barrel through different sized sieve holes and enter the different gaps separated by the inner barrel, thus achieving the effect of sorting down. At the same time, the down particles can enter the collection component below for individual sorting. S3: Then, the power unit is lifted by the lifting component to separate the linkage and the sealing part at its bottom. Then, the sealing part is removed from the screening barrel and the down in different gaps of the screening barrel is taken out by the external suction device.
[0013] Beneficial effects This invention provides a down feather one-way sorting machine and its usage method. Compared with the prior art, it has the following advantages: (1) This application can drive the screening barrel to rotate rapidly, use centrifugal force to separate impurities mixed in the down raw material, and can prevent impurities from clogging the screen holes through the intermittent reciprocating lifting and lowering inside the screening barrel and the stirring paddle and scraper opposite to the rotation direction of the screening barrel, while avoiding the phenomenon of down and impurities being separated into layers, thus improving the overall impurity removal and sorting effect.
[0014] (2) This application can easily separate the closed cover from the sorting tank and separate the connecting cover from the screening barrel, so that the operator can use the external suction device to classify and take down materials in different gaps inside the screening barrel, which is convenient for loading and unloading.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1: Please see Figures 1 to 6 A down sorting machine includes a sorting tank 1, a screening barrel 2 located inside the sorting tank 1, a power unit 3 located above the sorting tank 1, a lifting assembly 4 located on one side of the sorting tank 1, and a collection assembly 5 located below the sorting tank 1. It also includes a separation assembly 6 for sorting down and filtering large-volume impurities in the down. Among them, the screening barrel 2 includes several screening chambers arranged radially, and the diameter of the screen holes on the screening chambers decreases step by step from the inside to the outside. The separation component 6 includes a stirring paddle 604 disposed in the screening chamber at the center position, which is used to rotate to push down. A scraper 605 is provided at the end of the stirring paddle 604 for scraping off the down adhering to the screen holes. The stirring paddle 604 moves up and down along the axis of the screening barrel 2 during rotation. The separation assembly 6 also includes a bracket 601 fixedly connected inside the sorting tank 1. An internally threaded sleeve 602 is provided through the bracket 601. A reciprocating screw 603 is threaded through the internally threaded sleeve 602. The top end of the reciprocating screw 603 extends movably into the screening barrel 2 and is connected to the stirring paddle 604. The down feather sorting machine also includes the following steps during sorting: S1: The lifting component 4 lifts the power unit 3 to load the down raw material into the innermost screening chamber of the screening barrel 2, and then the lifting component 4 is reset. S2: The power unit 3 performs air separation on the down inside the screening barrel 2, and at the same time drives the screening barrel 2 and the separation component 6 through the first drive component 7 and the second drive component 8, so that the stirring paddle 604 and the scraper 605 stir the down, so that the down and impurities are separated, while avoiding the screen holes on the innermost inner barrel of the screening barrel 2 from being blocked. Large impurities in the down are filtered into the innermost screening chamber of the screening barrel 2. At the same time, different components in the down enter the screening barrel 2 through the screen holes of different sizes and enter the different gaps separated by the inner barrel, thus achieving the effect of sorting down. Meanwhile, the down particles in the down can enter the collection component 5 below to achieve single-item sorting. S3: Then, the power unit 3 is lifted by the lifting component 4, so that the linkage 303 at its bottom is separated from the sealing component 201. Then, the sealing component 201 is removed from the screening barrel 2, and the down in different gaps of the screening barrel 2 is taken out by the external suction device. Furthermore, the sorting tank 1 is provided with a first drive assembly 7 for driving the screening barrel 2 to rotate, including a second bracket 701 rotatably sleeved on the outside of the internal threaded sleeve 602, a third bracket 702 welded to the bottom of the sorting tank 1, a drive device 703 provided on the third bracket 702, a transmission shaft 704 provided on the output shaft of the drive device 703, and a gear set 705 that drives each other between the transmission shaft 704 and the bottom of the second bracket 701. The first drive component 7 can drive the second support 701 to rotate, thereby enabling the screening barrel 2 to rotate. Furthermore, the sorting tank 1 is provided with a second drive assembly 8 for driving the separation assembly 6 to work, including a driven intermittent gear 801 provided at the bottom end of the reciprocating screw 603, a linkage shaft 802 rotatably connected to the support 702, a driving intermittent gear 803 provided on the linkage shaft 802, and a gear set 804 that drives each other on the linkage shaft 802 and the transmission shaft 704. In this embodiment, gear set 705 and gear set 804 are both meshing gear sets or sprocket sets; The second drive assembly 8 can drive the reciprocating screw 603 to rotate and rise intermittently, thereby driving the stirring paddle 604 and scraper 605 to stir the down. A detachable sealing component 201 is installed on the screening barrel 2; The power unit 3 includes a closed cover 301 disposed above the sorting tank 1, a connecting cover 302 disposed through the closed cover 301, a linkage 303 rotatably disposed at the bottom of the connecting cover 302, a fan 304 disposed on the closed cover 301, and the air outlet of the fan 304 extending into the connecting cover 302. The lifting assembly 4 includes a telescopic component. The fixed end of the telescopic component is connected to the outer wall of the sorting tank 1. A bracket is welded to the outer wall of the enclosure 301. The bracket is connected to the telescopic end of the telescopic component. The telescopic component can be a hydraulic cylinder or an electric push rod, which are existing technologies and will not be described in detail here. The collection component 5 includes a collection box 501 disposed at the bottom of the sorting tank 1, a dust filter 502 disposed on the outside of the collection box 501, and a box door 503 disposed on the outside of the collection box 501. Collection box 501 is used to collect the sorted fluff separately for easy retrieval later. In use, the down raw material is placed into the screening barrel 2. Then, the telescopic component drives the sealing cover 301 to descend, making it fit against the sorting tank 1. At the same time, the connecting cover 302 inside is connected to the sealing part 201 on the screening barrel 2 through the linkage component 303. The two can rotate synchronously. At this time, the drive device 703 is started. The drive device 703 can drive the support 701 to rotate the screening barrel 2 through the gear set 705 on the transmission shaft 704. The gear set 804 drives the linkage shaft 802 to rotate the active intermittent gear 803. The active intermittent gear 803 works with the driven intermittent gear 801 to drive the reciprocating screw 603 to rotate intermittently. At the same time, since the internal threaded sleeve 602 is fixed, the reciprocating screw 603 will reciprocate up and down when rotating, thereby driving the stirring paddle 604 and scraper 605 to reciprocate up and down and rotate, thereby stirring and separating the down, preventing stratification, and avoiding clogging.
