DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment: A down clustering device, such as Figure 1-Figure 8 As shown, it includes a shell 1, which is a cylindrical structure with an inner cavity. A support plate 2 for carrying down raw materials and a clustering mechanism are provided in the inner cavity of the shell 1. The support plate 2 is adapted to the inner cavity of the shell 1 and is a circular structure. A plurality of filter holes 201 are provided on the support plate 2. The aperture of the filter holes 201 is smaller than that of the down to prevent the down from passing through the filter holes 201. The clustering mechanism includes an eccentric wheel 3 and a combing frame 4. The combing frame 4 and the eccentric wheel 3 are respectively located above and below the support plate 2, wherein the eccentric wheel 3 rotates to hit the lower surface of the support plate 2 to vibrate the support plate 2, and the clustered down is dispersed by the vibration of the support plate 2, and the clustered down is vibrated upward and falls back to form a tumbling state. The combing frame 4 rotates along the inner cavity of the shell 1. During the rotation of the combing frame 4, the clustered down is dispersed by hitting the tumbling state, and the clustered down is dispersed by combing the clustered down located on the upper surface of the support plate 2.

[0035] By setting an eccentric wheel 3, the eccentric wheel 3 is used to hit the support plate 2 to make the support plate 2 vibrate, and the support plate 2 is vibrated to disperse the balled down, and the balled down is vibrated upward and falls back to form a tumbling state; by setting a combing frame 4, the combing frame 4 is used to hit the balled down in the tumbling state to further disperse the balled down, and at the same time, the combing frame 4 is used to comb and group the balled down on the upper surface of the support plate 2 that has not been vibrated upward, and the balled down is grouped by combining dynamic grouping and static grouping to improve the grouping effect and grouping efficiency. At the same time, during the grouping process, the impurities attached to the down fall off from the down due to the vibration, impact and combing of the down quilt, and pass through the filter hole 201 of the support plate 2 to separate from the down. Preferably, the support plate 2 is made of metal, and its thickness is controlled so that the support plate 2 can produce a vibration effect when it is hit. At the same time, the rotation speed of the combing frame 4 is controlled to avoid the down quilt from being damaged by impact.

[0036] Specifically, Figure 2 and Figure 3 As shown, the combing frame 4 includes a first bracket 401, a second bracket 402, a first combing rod 403 and a second combing rod 404. The first bracket 401 and the second bracket 402 are located above the support plate 2 and are arranged parallel to the support plate 2. The first bracket 401 is vertically connected to the second bracket 402, that is, the first bracket 401 and the second bracket 402 form a cross structure. The connection between the first bracket 401 and the second bracket 402, the center of the second bracket 402, the center of the second bracket 402 and the center of the support plate 2 are coaxially arranged. The first combing rods 403 are respectively vertically installed on both sides of the first bracket 401, and the first combing rods 403 located on the same side of the first bracket 401 are arranged at equal intervals. The second combing rods 404 are respectively vertically installed on both sides of the second bracket 402, and the second combing rods 404 located on the same side of the second bracket 402 are arranged at equal intervals. There is a first combing rod 403 between two adjacent second combing rods 404. By setting the first combing rod 403 and the second combing rod 404, during the synchronous rotation of the first combing rod 403 and the second combing rod 404, the tumbling clumped down are impacted and clustered, and the clumped down located on the upper surface of the support plate 2 that has not been vibrated upward is combed and clustered; at the same time, by setting a first combing rod 403 between two adjacent second combing rods 404, dead corners are avoided in the combing and clustering process.

[0037] Further, such as Figure 4As shown, the ends of the first combing rod 403 and the second combing rod 404 are both installed with a four-sided platform 405, and an L-shaped structure is formed between the four-sided platform 405 and the first combing rod 403, and between the four-sided platform 405 and the second combing rod 404. The four-sided platform 405 is used to lift the down in front of the four-sided platform 405 to the upper surface of the four-sided platform 405, and then slides down from both sides of the four-sided platform 405. By performing circumferential and radial motions on the down at the same time, the down is placed in different flipping states, and the down is further divided into groups to improve the grouping effect. At the same time, the four-sided platform 405 on the first combing rod 403 and the four-sided platform 405 on the second combing rod 404 are arranged at intervals so that the down on the upper surface of the support plate 2 can be in a flipping state.

[0038] Preferably, the lower surface of the quadrangular pyramid 405 is parallel to the upper surface of the support plate 2 and abuts against the support plate 2. With the above design, the down blocking the filter hole 201 can be separated from the filter hole 201 to avoid the down blocking the filter hole 201, thereby facilitating the separation of impurities through the filter hole 201.

[0039] Preferably, the upper surface of the quadrangular platform 405 is provided with an upwardly convex protrusion 406. The protrusion 406, on the one hand, forms a height difference between the down feathers on the upper surface of the quadrangular platform 405, so as to facilitate the separation of the down feathers, and on the other hand, facilitates the down feathers on the upper surface of the quadrangular platform 405 to slide off from both sides of the quadrangular platform 405 quickly.

[0040] Further, such as Figure 1 and Figure 2 As shown, a fan 5 is installed on the outer wall of the housing 1 above the support plate 2, and the air outlet of the fan 5 is connected to the inner cavity of the housing 1. The outer wall of the housing 1 is provided with a discharge interface 6 opposite to the fan 5, and the discharge interface 6 is connected to the inner cavity of the housing 1. When the down clustering process is completed, the fan 5 inputs air into the inner cavity of the housing 1 through its air outlet, and the air blows the down to move outward through the discharge interface 6.

[0041] Preferably, the air inlet of the fan 5 is connected to the outside air, and a filter is provided at the air inlet to filter the air before inputting it into the inner cavity of the shell 1; at the same time, a filter is installed at the air outlet of the fan 5 to prevent the down from entering the fan 5 when clustering and affecting the subsequent operation of the fan 5.

[0042] Preferably, a certain distance is provided between the air outlet and the discharge interface 6 of the fan 5 and the support plate 2 to prevent the down from entering the air outlet and the discharge interface 6 of the fan 5 when the down is clustered; at the same time, the discharge interface 6 is sealed when the down is clustered.

[0043] Preferably, a feed interface 16 is provided on the outer wall of the shell 1 between the support plate 2 and the first bracket 401. The feed interface 16 is communicated with the inner cavity of the shell 1. A feed cover 17 is installed on the feed interface 16. During the down clustering and outward transfer of the down, the feed cover 17 seals the feed interface 16.

[0044] like Figure 2 As shown, cylinders 7 are installed on both sides of the first bracket 401, and the output end of the cylinder 7 is connected to a baffle 8, which is located below the first bracket 401 and the second bracket 402, and the first combing rod 403 and the second combing rod 404 are arranged through the baffle 8. By setting the baffle 8, on the one hand, in the process of down grouping, the up-floating of down is restricted, and on the other hand, in the process of the down being transferred outward, by lowering the baffle 8 to the discharge interface 6, the shielding and diversion effects of the baffle 8 are utilized to enhance the blowing effect of the fan 5, so that the down can be quickly transferred outward.

[0045] Furthermore, a first motor 9 is installed on the outer wall of the housing 1, and a first connecting rod 10 is connected to the output end of the first motor 9, and the end of the first connecting rod 10 is connected to the eccentric wheel 3; when the first motor 9 is running, the eccentric wheel 3 is driven to rotate through the first connecting rod 10, and the rotation of the eccentric wheel 3 is used to hit the support plate 2 to vibrate the support plate 2. Preferably, the eccentric wheel 3 can be located at the center of the support plate 2, or multiple eccentric wheels 3 can be used, which are respectively distributed at various positions below the support plate 2.

[0046] Furthermore, a second motor 11 is installed at the top of the housing 1, and a second connecting rod 12 is connected to the output end of the second motor 11. The end of the second connecting rod 12 passes through the top of the housing 1 and extends into the inner cavity of the housing 1. The end of the second connecting rod 12 is connected to the combing frame 4. When the second motor 11 is running, the combing frame 4 is driven to rotate through the second connecting rod 12.

[0047] A lower hopper 13 is installed in the inner cavity of the shell 1 below the support plate 2, and a collection box 14 is provided below the lower hopper 13; the collection box 14 is a pull-out type for collecting impurities falling off the down; the lower hopper 13 plays a role in diversion.

[0048] like Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, a cover mechanism 15 for controlling the conduction and cutoff of the lower hopper 13 is provided above the lower hopper 13. When the down is clustered, the cover mechanism 15 is opened to conduct between the support plate 2 and the lower hopper 13, so that impurities pass through the filter holes 201 on the support plate 2 and are transferred to the collection box 14 through the lower hopper 13; when the down clustering process is completed, the cover mechanism 15 is closed to cut off between the support plate 2 and the lower hopper 13 to prevent the fan 5 from blowing the down to transfer, and forming a negative pressure at the lower hopper 13 to suck the impurities in the collection box 14 to the discharge interface 6.

[0049] Specifically, the cover mechanism 15 includes a first cover 1501, a second cover 1502 connected to the first cover 1501, and an inner ring 1503 located in the inner cavity of the second cover 1502 and rotatably connected to the second cover 1502. A first through hole 1504 is opened at the center of the first cover 1501, a second through hole 1505 corresponding to the first through hole 1504 is opened at the center of the second cover 1502, and four gears are rotatably connected in the inner cavity of the second cover 1502. The inner ring 1503 and the second cover plate 1502 are coaxially arranged, and the inner side wall of the inner ring 1503 is provided with a first rack 1507 corresponding to each position of the gear 1506, that is, the number of the first racks 1507 is four, and they correspond to the gears 1506 one by one, and each first rack 1507 is meshed with the corresponding gear 1506, and the inner cavity of the second cover plate 1502 corresponds to each position of the gear 1506. The inner ring 1503 is slidably connected with a slide plate 1508, that is, the number of slide plates 1508 is four, and each slide plate 1508 corresponds to the gear 1506 one by one. Each slide plate 1508 is located above the second through hole 1505 and meshes with the corresponding gear 1506. A handle 1509 is provided on the outer wall of the inner ring 1503, and the end of the handle 1509 penetrates the outside of the housing 1. The inner ring 1503 is rotated by turning the handle 1509, and the gear 1506 is driven to rotate by the rotation of the inner ring 1503, and the inner ring 1503 is rotated by rotating the gear 1506, and the inner ring 1503 is rotated by rotating the gear 1506. The gear 1506 drives the slide plate 1508 to slide to open and close the second through hole 1505, that is, when the four slide plates 1508 slide relative to each other, the four slide plates 1508 move closer to each other and block the second through hole 1505, so that the first through hole 1504 and the second through hole 1505 are cut off; when the four slide plates 1508 slide toward each other, the four slide plates 1508 separate from each other and do not block the second through hole 1505, so that the first through hole 1504 and the second through hole 1505 are connected.

[0050] Further, such as Figure 6-Figure 8As shown, the slide plate 1508 includes an isosceles right triangle portion 15081 and a trapezoidal portion 15082, and the hypotenuse of the isosceles right triangle portion 15081 is connected to the upper base of the trapezoidal portion 15082, and the right angle of each isosceles right triangle portion 15081 is located at the center of the second cover plate 1502, that is, located above the second through hole 1505, the right angles of two adjacent isosceles right triangle portions 15081 abut against each other, and the four isosceles right triangle portions 15081 move toward and relative to each other to open and close the second through hole 1505, and the lower base of the trapezoidal portion 15082 is installed with a second rack 1510, and the second rack 1510 meshes with the gear 1506. When the four gears 1506 respectively drive the corresponding trapezoidal parts 15082 to slide relative to each other, each trapezoidal part 15082 respectively and synchronously drives the isosceles right triangle part 15081 connected thereto to slide, the four isosceles right triangle parts 15081 move closer to each other, and block the second through hole 1505, so that the first through hole 1504 and the second through hole 1505 are cut off; when the four gears 1506 respectively drive the corresponding trapezoidal parts 15082 to slide toward each other, each trapezoidal part 15082 respectively and synchronously drives the isosceles right triangle part 15081 connected thereto to slide, the four isosceles right triangle parts 15081 separate from each other, do not block the second through hole 1505, so that the first through hole 1504 and the second through hole 1505 are conductive.

[0051] Furthermore, a waist-shaped hole 15083 is formed on the trapezoidal portion 15082 , and a slider 15084 is slidably connected in the waist-shaped hole 15083 , and the slider 15084 is connected to the inner cavity of the second cover plate 1502 .
