Description

Technical Field

[0001] This invention belongs to the field of down sorting technology, specifically relating to an anti-clogging down sorting device and sorting method. Background Technology

[0002] With the increasing popularity of winter down garments and the growing demand, the requirements for down quality are also becoming higher, especially for some export down garments, which need to have a pure down content of over 90%. During the production process, down needs to undergo a sorting process to separate the mixed down and feathers, selecting only the down that meets the requirements.

[0003] Some technical solutions for down sorting have also emerged in the existing technology, such as a Chinese patent with publication number CN108203849A, which discloses a sorting device for convenient coarse sorting of down in down production. The device uses the wind force of a fan and the air pressure of a screening box to coarsely separate down and feathers, avoiding the need for manual sorting. It also avoids the situation where the screening structure is not ideal and down and feathers are mixed up, thus improving the screening quality of down.

[0004] However, this patent does not separate the down during the wind-sorting process. Some of the down and feathers that are stuck together cannot be separated, causing the down to be discarded along with the feathers, thus affecting the sorting efficiency and quality of the down. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-clogging down sorting device and sorting method to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A clog-resistant down sorting device includes:

[0008] The sorting box features a vertically continuous design.

[0009] An arc-shaped guide rail is located at the top of the sorting box;

[0010] A conveyor that extends into the sorting bin; the conveyor is used to transport unsorted blended fibers.

[0011] A blower located at the bottom of the sorting box is used to provide airflow to the sorting box;

[0012] A fixed plate is provided inside the sorting box, and the fixed plate has several through holes along its circumference;

[0013] A drive motor mounted on a fixed disk;

[0014] A grinding roller connected to the output shaft of a drive motor, the grinding roller being located below a fixed disc;

[0015] An interception assembly is provided on the fixed plate between the roller and the down. The interception assembly is used to initially intercept the down mixture and allow the down to pass through. The interception assembly includes a sleeve on which a plurality of grids are provided along its circumference.

[0016] When the drive motor rotates the rollers, it rubs the down that is blocked at the grid, causing the down and feathers to separate. The down moves to the arc-shaped guide rail away from the sorting box under the action of the airflow blown by the blower. The feathers cannot pass through the grid and are blocked. The blower stops working and the feathers fall under the action of gravity.

[0017] The rollers are made of rubber or silicone material.

[0018] A coil spring is provided between the grid and the sleeve. The grids connected to the coil spring are in contact with each other and several grids are staggered to form a complete circle. A stop bar is provided at the bottom of the uppermost grid.

[0019] The bottommost grid is fan-shaped with a sector angle of less than 5°.

[0020] The sidewalls of the grid are serrated.

[0021] The drive motor is a dual-shaft motor, and the output shaft of the drive motor away from the roller is equipped with a stirring roller.

[0022] The sorting box is provided with several connecting rods arranged diagonally. A second coil spring is sleeved on the connecting rod to drive the connecting rod to rotate. One end of the second coil spring is located on the sorting box. A rectangular plate is sleeved on the connecting rod. The rectangular plate remains vertical under the action of airflow generated by the blower. When the blower stops, the rectangular plate forms an inclined track.

[0023] A method for sorting down using the aforementioned anti-clogging down sorting device includes the following steps:

[0024] S1: Place the blended fabric that needs to be sorted on the conveyor and use the conveyor to transport the blended fabric into the sorting box;

[0025] S2: Start the blower. The airflow generated by the blower blows the mixed down falling on the conveyor upwards toward the fixed plate. When the mixed down passes through the grid, it is intercepted. The drive motor drives the roller to rotate. When the roller sweeps across the grid surface, it rubs the mixed down, causing the down and feathers that are stuck together to move relative to each other. Under the action of the airflow, the down passes through the grid and the fixed plate, and is carried away from the sorting box by the arc-shaped guide rail, leaving the feathers.

[0026] S3: Adjust the blower's airflow and repeat the separation process of S2 2-3 times on the down that has been separated and carried away in S2 to sort out the down that meets the standards.

[0027] The beneficial effects of this invention are as follows:

[0028] This invention separates mixed down from feathers by kneading it and using strong wind to carry away the desired high-quality down, thereby maximizing the recovery of down and improving the quality and efficiency of down sorting. Attached Figure Description

[0034] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Example 1

[0036] like Figure 1-4 As shown, an anti-clogging down sorting device includes:

[0037] Sorting box 1 is designed with a through-type vertical direction;

[0038] Arc-shaped guide rail 2 is located at the top of sorting box 1;

[0039] Conveyor 3 extends into sorting box 1 and is used to transport unsorted mixed down feathers;

[0040] A blower 4 is located at the bottom of the sorting box 1, and the blower 4 is used to provide airflow to the sorting box 1.

[0041] A fixed disk 5 is provided inside the sorting box 1, and the fixed disk 5 has several through holes along its circumference;

[0042] A drive motor 6 is mounted on a fixed disk 5;

[0043] The roller 7 is connected to the output shaft of the drive motor 6 and is located below the fixed plate 5.

[0044] An interception assembly is provided on the fixed plate 5 between the roller 7 and the down. The interception assembly is used to initially intercept the down and allow fine down to pass through. The interception assembly includes a sleeve 8, on which a plurality of grids 9 are provided along its circumference.

[0045] It should be noted that during the sorting process, the conveyor 3 transports the unsorted mixed down into the sorting box 1, where it falls from the conveyor 3. Simultaneously, the blower 4 delivers a high-speed airflow upwards, which blows the mixed down towards the fixed plate 5, where it is intercepted at the grid 9. The drive motor 6 rotates the roller 7, which crushes and kneads the mixed down at the grid 9 during rotation, separating the down from the feathers. Under the influence of the high-speed airflow, the down passes through the grid 9, while the feathers cannot pass and accumulate there. After passing through the grid 9, the down moves to the curved guide rail 2 under the influence of the airflow and exits the sorting box 1 under its guidance. After the sorting is completed within the set time, the blower 4 and conveyor 3 are stopped, and the feathers intercepted at the grid 9 are removed to prevent the feathers from blocking the grid 9 and affecting the normal passage of down.

[0046] The roller 7 is made of rubber or silicone material. Because the multiple grids 9 have thickness, the roller 7 needs to be in contact with each grid 9. The roller 7 made of rubber or silicone material has good friction and flexibility, which can knead the mixed down while also producing a certain deformation. Thus, it can make contact with the surface of each grid 9 without interfering with the grid 9 and being unable to rotate.

[0047] A coil spring 10 is provided between the grid 9 and the sleeve 8. The grids 9 connected to the coil spring 10 are in contact with each other, and several grids 9 are staggered to form a complete circle. A stop bar 11 is provided at the bottom of the uppermost grid 9. The grid 9 can rotate freely on the sleeve 8. When rotating, it drives the coil spring 10 to rotate, thereby tightening the coil spring 10. The drive motor 6 continuously changes its rotation direction, so that the rotation direction of the grinding roller 7 also continuously changes. When the grinding roller 7 is normally rubbing the mixed down, it does not contact the stop bar 11. When it is necessary to clean the down on the grid 9, the drive motor 6 keeps rotating in the same direction, so that the grinding roller 7 contacts the stop bar 11 when rotating, thereby causing the stop bar 11 to drive the grid 9 to rotate. When the grid 9 connected to the stop lever 11 rotates, it rotates relative to another adjacent grid 9 and gradually overlaps with the adjacent grid 9. During the overlap process, due to the contact between the surfaces of the two adjacent grids 9, the flakes on the uppermost grid 9 are scraped off by the edges of the adjacent grids 9, until all the grids 9 overlap to the size of one grid 9. The drive motor 6 reverses again, and the overlapping grids 9 rotate back under the action of their respective first coil springs 10 and restore their previous circular shape.

[0048] The bottommost grid 9 is fan-shaped with a sector angle of less than 5°. There is no grid 9 at the bottom of the bottommost grid 9 to clean it. The sector angle of the bottommost grid 9 is set to a small angle, so that the area of ​​the bottommost grid 9 is small, and the number of feathers gathered or stuck on its surface is small, thus minimizing the impact on the normal passage of down.

[0049] The sidewalls of the grid 9 are provided with serrations. When the grid 9 moves, the serrations on the sidewalls can easily scrape off the hair pieces stuck at the bottom of the adjacent grid 9, and can also cut off the hair pieces. It has a good removal effect on deeply stuck hair pieces.

[0050] Example 2

[0051] The drive motor 6 is a dual-shaft motor. The output shaft of the drive motor 6 away from the roller 7 is equipped with a stirring roller 12. The output shaft above the drive motor 6 is equipped with a stirring roller 12. During the rotation, the stirring roller 12 beats the floating down a second time. It can beat some of the mixed down that cannot fly out of the sorting box 1, and can further separate the down and the secondary down formed by small feathers.

[0052] The sorting box 1 is equipped with several connecting rods arranged diagonally. A second coil spring is fitted onto each connecting rod to drive its rotation. One end of the second coil spring is attached to the sorting box 1. A rectangular plate 13 is fitted onto the connecting rod. The strong airflow generated by the blower 4 acts on the rectangular plate 13, causing its surface to experience significant wind force. This wind force keeps the rectangular plate 13 vertical, allowing strong airflow to pass through normally. When the rectangular plate 13 is vertical, the second coil spring is tightened. When the blower 4 stops working, the second coil spring drives the rectangular plate 13 to rotate backward, forming an inclined track. Fallen fibers land on this inclined track and are guided to a set point for discharge from the sorting box 1, preventing the fibers from affecting the blower 4 and preventing them from being carried back into the grid 9.

[0053] A method for sorting down using the aforementioned anti-clogging down sorting device includes the following steps:

[0054] S1: Place the down feathers to be sorted on the conveyor 3, and use the conveyor 3 to transport the down feathers into the sorting box 1;

[0055] S2: Start blower 4. The airflow generated by blower 4 blows the down falling on conveyor 3 upward toward fixed plate 5. The down is intercepted when it passes through grid 9. Drive motor 6 drives roller 7 to rotate. When roller 7 sweeps across the surface of grid 9, it rubs the down, causing the down and feathers that are stuck together to move relative to each other. Under the action of airflow, the down passes through grid 9 and fixed plate 5, and is carried away from sorting box 1 by arc guide rail 2 under the action of airflow, leaving feathers.

[0056] S3: Adjust the airflow of blower 4 and repeat the separation process of S2 2-3 times for the down that was separated and carried away in S2. This sorts out the down that meets the standards. The down content obtained in a single sorting is relatively low because the airflow of blower 4 is strong, and some small feathers are also blown away. The down collected after being blown away is sorted repeatedly, with the blower 4's workload reduced each time, so that a lower airflow is sufficient to collect the down. The down collected at this point is high-quality down that meets the standards.

[0057] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
