Description

Technical Field

[0001] The utility model relates to the technical field of down sorting, in particular to a multi-layer screening down sorting device. Background Art

[0002] As a high-quality thermal insulation material, down is widely used in clothing, bedding, and outdoor equipment. As people's expectations for quality of life improve, market demand for down is also growing. However, the quality and performance of down are affected by many factors, such as down type, filler purity, fluffiness, and impurity content. Therefore, how to efficiently and accurately sort and screen down has become a pressing issue in the industry.

[0003] After searching, the Chinese patent document with patent number CN202320051059.8 discloses a multi-layer screening down sorting device. The above scheme arranges multiple filter screens with different sized filter holes from bottom to top inside a fixed box, which can filter larger feathers first and then filter medium-sized feathers. In this way, the down can quickly pass through multiple filter screens through the cooperation of the blower, connecting pipe, air supply pipe and fixed pipe, and sort out feathers of different sizes, avoiding the concentration of a large amount of down in one place, affecting the sorting efficiency of the down.

[0004] Although the above technology filters down through filters with different apertures, when the down is driven to flow by wind, since the above device adopts a vertical structure, the filters are distributed in an upper and lower position relationship, resulting in the down being likely to adhere to the filter holes when passing through the filter. Further, when the wind flows from bottom to top, the wind force in the upper layer is weak, and the down cannot effectively pass through the filter holes, which may cause the filter holes to be clogged, further resulting in poor filtering and sorting effects of the down. Utility Model Content

[0005] Technical problems solved

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a down sorting device with multi-layer screening, which can solve the problem of low sorting efficiency caused by down adhering to the filter holes in the prior art.

[0007] Technical Solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] The utility model provides a multi-layer screening down sorting device, comprising a frame, two groups of the frames are movably mounted with mounting platforms, springs are mounted on the upper and lower surfaces of the mounting platforms, a sleeve is mounted between the two groups of the mounting platforms, a sorting mechanism is mounted on the sleeve, and the sorting mechanism is used to filter down of different sizes, a motor is mounted on the surface of one group of the mounting platforms, an eccentric block is mounted on the output shaft of the motor, the sleeve is mounted on the eccentric block, a rotary joint is mounted on the other group of the mounting platforms, the sleeve is adaptably inserted in the rotary joint, a connecting hose is mounted on the rotary joint, and the rotary joint is connected to a fan through the connecting hose, and an air inlet is provided on a section of the surface of the sleeve inserted inside the sorting mechanism.

[0010] Furthermore, the sorting mechanism includes a primary bin, an internal bin and a sealed bin sequentially installed on the sleeve; the surfaces of the primary bin and the internal bin are both provided with evenly distributed filter holes; the aperture of the filter holes on the primary bin is smaller than that of the filter holes on the sealed bin; and the surface of the sealed bin is provided with exhaust holes.

[0011] Furthermore, the internal chambers are provided as at least one group located between the primary chamber and the sealing chamber.

[0012] Furthermore, the air inlet holes are distributed throughout the primary chamber, the internal chamber and the sealed chamber.

[0013] Furthermore, stirring rods are evenly distributed on the inner walls of the primary bin and the inner bin.

[0014] Beneficial effects

[0015] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0016] The utility model adopts the structural arrangement of the sorting mechanism, so that after down is placed in the sorting mechanism, air flow is introduced into the sorting mechanism, and the sorting mechanism is controlled to jump up and down synchronously during the rotation process, so that the down in the sorting mechanism is quickly filtered into different chambers according to the filter holes of different aperture sizes under the action of centrifugal force, air pressure and vibration screen, thereby realizing rapid sorting of down according to size. In addition, the sorting mechanism adopts a horizontal installation method, so that air flow can enter multiple filter chambers synchronously, avoiding the clogging of the filter holes in the inner filter chamber, which will lead to poor flow effect of down in the outer filter chamber and poor filtering effect.

[0017] During the sorting process, the down can be quickly discharged from the filter holes through up and down vibration and air pressure. Even if the down is blocked in the filter holes, it will be quickly released under the action of vibration and air pressure, effectively avoiding the down blocking the filter holes and causing low sorting efficiency.

[0018] Moreover, during the sorting process, the down clumps can be avoided from being broken up, the down can be separated, and the sorting efficiency of the down can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example:

[0028] Please refer to the attached Figure 1-4This proposal proposes a multi-layer screening down sorting device, in which a sorting mechanism 2 is installed between two sets of frames 1. The sorting mechanism 2 is used to filter and sort the down according to size after filling it. A mounting platform 3 is movably installed on the frame 1, and a sleeve 5 is hingedly installed between the two sets of mounting platforms 3. The sorting mechanism 2 is installed on the sleeve 5. At the same time, a motor 6 is installed on one set of mounting platforms 3. The motor 6 is used to drive the sleeve 5 to rotate, further controlling the sorting mechanism 2 during rotation to accelerate the filtering effect of the down through centrifugal force to improve the sorting efficiency of the down. An eccentric block 7 is installed on the output shaft of the motor 6, and the sleeve 5 is installed on the outside of the eccentric block 7. Further, when the motor 6 is turned on and drives the eccentric block 7 connected to the sleeve 5 to rotate, the sleeve 5 will swing under the action of the centrifugal force generated by the rotation of the eccentric block 7. The mounting platform 3 is movably mounted in the frame 1, and springs 4 are installed on the upper and lower surfaces of the mounting platform 3. The frame 1 further limits the vibration direction of the mounting platform 3, and under the elastic force of the spring 4, the mounting platform 3 jumps up and down in the frame 1, further causing the sleeve 5 to drive the sorting mechanism 2 to jump in the up and down direction, thereby controlling the down in the sorting mechanism 2 to be filtered and sorted during the vibration screening process.

[0029] Specifically, a rotary joint 8 is mounted on another set of mounting platforms 3, and a sleeve 5 is inserted into the rotary joint 8. A connecting hose 9 is installed on the rotary joint 8 and connected to a fan 10 through the connecting hose 9. An air inlet 11 is provided on a portion of the sleeve 5 inserted into the sorting mechanism 2. When down enters the sorting mechanism 2 for sorting, the fan 10 is turned on and supplies air into the sleeve 5. The airflow enters the sorting mechanism 2 through the air inlet 11, blowing the down inside the sorting mechanism 2 and accelerating the filtering and sorting efficiency of the down.

[0030] The sorting mechanism 2 is configured as a frustum, and one end of the sorting mechanism 2 with a larger diameter is configured as an opening to facilitate the removal of the sorted down.

[0031] More specifically, the sorting mechanism 2 includes a primary bin 201, an internal bin 202, and a sealed bin 203, which are sequentially mounted on the sleeve 5. The internal bin 202 is provided as at least one group located between the primary bin 201 and the sealed bin 203. The surfaces of both the primary bin 201 and the internal bin 202 are provided with evenly distributed filter holes 204, through which down is filtered. The filter holes 204 on the primary bin 201 have a smaller aperture than the filter holes 204 on the stirring rod 205. This allows the primary bin 201 and the internal bin 202 to filter down of different sizes, further enabling down sorting by size. Furthermore, by setting the number of internal bins 202 and providing filter holes 204 of different sizes on multiple internal bins 202, the device can perform more precise size sorting of down.

[0032] The primary bin 201 is filled with down to be sorted. The rotation of the sleeve 5 drives the primary bin 201 to rotate synchronously, causing the down in the primary bin 201 to be flung outward under the action of centrifugal force. Simultaneously, air inlet holes 11 provided on the surface of the sleeve 5 extend throughout the primary bin 201, the internal bin 202, and the sealed bin 203. This allows airflow in the sleeve 5 to simultaneously enter the primary bin 201, the internal bin 202, and the sealed bin 203 through the air inlet holes 11, thereby promoting the flow of down in the primary and internal bins 201, 202, and forcing smaller down in the primary bin 201 to pass through the filter holes 204 and into the sealed bin 203, achieving preliminary sorting of the down.

[0033] Similarly, when the down enters the sealed chamber 203, the airflow will simultaneously blow the smaller down in the sealed chamber 203, and further filter the down through the filter holes 204 on the sealed chamber 203, so that the smaller down will pass through the filter holes 204 and enter the sealed chamber 203, further achieving multi-layer filtration of the down. Finally, the airflow may be discharged through the exhaust holes 206 on the sealed chamber 203.

[0034] In addition, the air inlet holes 11 arranged on the surface of the sleeve 5 are distributed throughout the primary chamber 201, the internal chamber 202 and the sealed chamber 203, so that there is always airflow in the primary chamber 201, the internal chamber 202 and the sealed chamber 203. Even if some of the filter holes 204 on the surface of the primary chamber 201 are blocked, it will not affect the flow and filtering effect of the down in the internal chamber 202.

[0035] After the down is filtered, the down of different sizes will be retained in the primary bin 201, the internal bin 202, and the sealed bin 203, respectively, thereby further realizing the sorting of down of different sizes.

[0036] The difference is that evenly distributed stirring rods 205 are provided on the inner walls of the primary bin 201 and the internal bin 202, so that when the primary bin 201 and the stirring rods 205 rotate, the stirring rods 205 will drive the synchronous rotation, and further enable the stirring rods 205 to stir and beat the down in the bin, thereby decomposing the down clumps and facilitating the filtering of the down.

[0037] It is worth noting that when down is stuck in the filter hole 204, the whole vibration of the sorting mechanism 2 and the air pressure of the air flow can cause the down to quickly fall off from the filter hole 204, thereby avoiding clogging of the down.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
