Description

A quantitative filling system Technical Field

[0001] The invention relates to a quantitative down filling system, belonging to the technical field of down production. Background Art

[0002] Down is one of the most core materials in down products such as down jackets and down quilts. Its usage is directly related to the thermal insulation effect. Therefore, the down filling volume is one of the key indicators to measure the quality of down products.

[0003] The down filling content of down products is primarily assessed by weight. However, down has a low density and is dry and fluffy, making it difficult to weigh efficiently and quickly. Current down products are often sewn into separate filling cavities, each filled with down. This effectively confines the down to specific areas, preventing it from clumping due to washing, friction, and other factors, which can lead to a loss of insulation.

[0004] Due to the requirements of warmth and aesthetics, the sizes of the filling cavities in down products often vary. This results in the designed down filling quantity in each cavity not always being equal. Down filling is often done continuously across multiple cavities. Therefore, the filling quantity must be adjusted promptly based on the actual filling of the cavity. As mentioned above, the nature of down makes it difficult to quickly and accurately weigh it, which results in consistently low down filling efficiency and accuracy. Summary of the Invention

[0005] In view of the above-mentioned defects in the prior art, the task of the present invention is to provide a quantitative down filling system, the purpose of which is to solve the problem of difficulty in quickly obtaining down of a specific weight that varies as required.

[0006] The technical solution of the present invention is as follows: a quantitative down filling system includes a down bin, in which air is blown to disperse and fall the down, a circulating conveyor belt is provided in the down bin, a number of down boxes are provided on the circulating conveyor belt, the down box has a down cavity with a variable volume and an open top, an air inlet and a down outlet are provided on both sides of the down cavity on the down box, and a fixed down scraping cover is provided in the down bin; when the down box passes through the down scraping cover, the down scraping cover is laterally covered on the top of the down box to seal the down cavity, and air is introduced through the air inlet so that the down in the down cavity is discharged from the down outlet along with the air.

[0007] Furthermore, the velvet box has at least one partition plate driven to translate by a driving mechanism, the velvet cavity is formed by the partition plate dividing the inner cavity of the velvet box, and the partition plate changes the volume of the velvet cavity when it moves.

[0008] The size of the pile cavity is controlled by moving the partition plate, and the volume of the sized pile cavity can be determined more accurately by the moving distance.

[0009] Furthermore, the partition plate is located at the bottom of the velvet box, the velvet cavity is located above the partition plate, and the partition plate moves up and down in the velvet box.

[0010] Furthermore, the partition plate is uprightly arranged in the velvet box, one side of the partition plate is the velvet cavity, and the partition plate moves laterally in the velvet box.

[0011] Furthermore, the air inlet and the down outlet are respectively arranged on the partition plate and a side wall of the down box, and the side wall is opposite to the partition plate.

[0012] By setting an air inlet or a down outlet on the movable partition plate, there is no need to worry about whether the air inlet or the down outlet will be blocked after the partition plate moves. No matter how the partition plate moves, the air inlet and the down outlet can be maintained at the optimal position on the down cavity, so that the down in the down cavity can be completely and quickly discharged.

[0013] Furthermore, the air inlet is a plurality of through holes evenly distributed on one side of the down cavity. The evenly distributed through holes allow the air intake of the down cavity to be evenly blown into the down cavity, making the airflow more widely distributed, reducing dead corners in the down cavity, and being more conducive to the complete discharge of the down.

[0014] Furthermore, the air inlet is a plurality of through holes evenly distributed on the partition plate, and an air cavity is provided on the back side of the partition plate facing away from the velvet cavity. The air cavity is connected to the through holes, and the inlet of the air cavity is led out to the wall of the velvet box by a flexible pipe.

[0015] Furthermore, the scraping cover is provided with docking portions on both sides, each of which is provided with an air source interface and a down outlet interface. When the scraping cover is laterally closed on the top of the down box to seal the down cavity, the air source interface is connected to the air inlet, and the down outlet interface is connected to the down outlet. In this way, the air source and down outlet pipelines do not need to move with the down box, simplifying the connection structure.

[0016] Furthermore, the circulating conveyor belt is upside down for conveying, and has an upper conveying surface and a lower return surface, and the scraping cover is arranged above the upper conveying surface and at the end of the upper conveying surface, so as to ensure that the down box has enough time to receive the down.

[0017] Furthermore, a feeding port is provided on one side of the down bin. A fluidizing plate is located below the feeding port. A settling area is formed on the side of the down bin away from the feeding port. The circulating conveyor is located in the settling area. Air is introduced into the down bin by the fluidizing plate, causing the down to disperse and fall in the settling area. Down boxes in the settling area collect the evenly distributed down, ensuring that the weight-to-volume ratio of the down collected in each box remains consistent, further improving the accuracy of the down output.

[0018] The advantages of the present invention compared with the prior art are:

[0019] Taking advantage of the fact that the weight-to-volume ratio of down is stable after it is dispersed and falls, the amount of down that can be held in the down box is changed by changing the volume of the down cavity, so as to control the weight of the down, avoid the weighing operation of the down, and do not need to repeatedly adjust the amount of down to meet the down weight requirements. It has a simple structure and high filling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the examples, but are not intended to limit the present invention.

[0026] Referring to Figures 1 to 5 , a quantitative down filling system according to this embodiment includes a down bin 1, with a feeding port 2 provided on one side of the top of the down bin 1 for replenishing down material into the down bin 1. A fluidizing plate 3 is provided on one side of the bottom of the down bin 1 below the feeding port. Air is blown into the down bin 1 through the fluidizing plate 3 to fluidize the down introduced through the feeding port 2. Since the fluidizing plate 3 is only provided on one side of the down bin 1, the airflow formed therefrom forms a gas circulation within the down bin 1. The down above the fluidizing plate 3 is blown upward, while on the other side of the down bin 1 (the area not covered by the fluidizing plate 3), the gas circulation points downward and carries the down downward, causing the down to disperse and fall, thus becoming a settling area.

[0027] The settling area of ​​the down bin 1 is equipped with a metering assembly, specifically comprising a circulating conveyor belt 4. Multiple down boxes 5 are spaced apart on the conveyor belt 4, driving the boxes 5 in a reciprocating motion. The boxes 5 are open at the top to receive the settled down. Inside the boxes 5 is a movable partition 14, which divides the boxes 5 into variable-volume down chambers 5a. In this embodiment, the boxes 5 are rectangular, but the present invention is not limited to this shape. The partition 14 is vertically positioned within the boxes 5 and is driven by a drive mechanism 13 for translation. The space enclosed by the partition 14 and the three side walls and bottom wall of the boxes 5 constitutes the down chamber 5a, located on one side of the partition. On the other side of the partition 14 is the power chamber 5b, within which the drive mechanism 13 is located. The drive mechanism 13 can utilize a screw assembly, hydraulic assembly, pneumatic assembly, or other similar means known in the art to push the partition 14, allowing for rapid adjustment of the volume of the down chamber 5a.

[0028] It should be pointed out that the partition plate 14 does not have to be arranged upright in the velvet box 5. In some embodiments, the partition plate 14 divides the velvet box 5 longitudinally, that is, the partition plate 14 moves up and down, and the velvet cavity 5a is enclosed above the partition plate 14 and the side walls of the velvet box 5, and the driving mechanism 13 is arranged under the partition plate 14.

[0029] Continuing with the example of the aforementioned upright partition plate 14, partition plate 14 is a perforated plate with a plurality of through-holes 19 formed on its surface. These through-holes 19 serve as air inlets for the down cavity 5a. In this embodiment, the side of partition plate 14 facing away from the down cavity 5a is the back side, which is provided with an air cavity 22. Air cavity 22 is connected to through-holes 19, that is, air cavity 22 communicates with the down cavity 5a through through-holes 19. Air cavity 22 is connected to air guide port 6 located on the first side wall of the down box 5 via a flexible conduit 8. The first side wall is parallel to the direction of movement of the endless conveyor belt 4. A down outlet 18 with a one-way valve is provided on the second side wall of the down box 5, opposite the first side wall. This one-way valve can only be opened outward, allowing airflow and down to be discharged only from the down cavity 5a through the down outlet.

[0030] The dosing assembly also includes a scraping cover plate 7 that is slidably sealed with the top of the velvet box 5. The scraping cover plate 7 is fixedly arranged in the velvet bin 1 above one end of the circulating conveyor belt 4. Specifically, the width of the scraping cover plate 7 is slightly larger than the width of the velvet box 5. One side of the scraping cover plate 7 is fixedly connected to the side wall of the velvet bin 1 through a transition plate 11. One side of the transition plate 11 is also provided with an arc-shaped shell 12 for matching the arc-shaped end of the circulating conveyor belt 4.

[0031] When the endless conveyor belt 4 drives the down box 5 to the scraping cover 7, the scraping cover 7 is laterally closed on the down box 5 to scrape off the excess down that exceeds the top of the down box 5, thereby keeping the height of the down in the down cavity 5a the same as that of the down box 5. At this time, the volume of the down settled in the down cavity 5a is the same as the volume of the down cavity 5a. Under this premise, it is only necessary to conduct an appropriate number of experiments to predetermine the settlement density of the down in the down cavity 5a, and then the weight of the down in the down cavity 5a can be quickly determined based on the volume of the down cavity 5a. The volume of the down cavity 5a can be quickly adjusted by moving the partition plate 14.

[0032] In the process of making down products, different filling cavities 5a are numbered and their filling amounts are predetermined. Then, through the intelligent system, the down boxes 5 with different numbers are matched one by one with the filling cavities 5a, and a control signal is sent to the driving mechanism 13 in the corresponding down box 5 according to the predetermined filling amount of each filling cavity 5a, and then the position of the partition plate 14 in the corresponding down box 5 is adjusted according to the control signal.

[0033] There are docking parts on both sides of the scraping cover plate 7, which are respectively slidably sealed with the first side wall and the second side wall of the velvet box 5, wherein the docking part slidably sealed with the first side wall is provided with an air source interface 21 that slides with the air guide port 6, and the air source interface 21 is connected to the air source 15 through the air pipe 17; the docking part slidably sealed with the second side wall is provided with a velvet outlet interface 20 that slides with the velvet outlet 18, and the velvet outlet interface is connected to the filling tube 16.

[0034] When the scraping cover 7 is laterally closed onto the down box 5, the top opening of the down cavity 5a is sealed by the scraping cover 7. At this point, the air source interface 21 is connected to the air guide port 6, and the down outlet interface 20 is connected to the down outlet 18. Compressed air from the air source 15 enters the air cavity 22 through the air pipe 17, the air source connector 21, the air guide port 6, and the flexible pipe 8. It then enters the down cavity 5a through the through hole 19 in the partition plate 14. Because the top of the down cavity 5a is sealed by the scraping cover 7, the compressed air, carrying down, overcomes the one-way valve at the down outlet 18 and enters the filling pipe 16. After the down in the down cavity 5a is completely purged, the air supply is cut off, and the cavity 5a follows the circulating conveyor belt 4 out of the scraping box 7 and returns to continue collecting settled down.

[0035] In this embodiment, the circulating conveyor belt 4 is turned upside down for conveying. The circulating conveyor belt 4 has an upper conveying surface and a lower return surface. When the down box 5 is on the upper conveying surface, the opening is above to receive down. When it is on the lower return surface, the opening is below, so that the down falling into the power chamber 5b falls and re-enters the gas circulation to be fluidized. No down will gather in the power chamber 5b. At this time, the driving mechanism 13 drives the partition plate 14 to move as needed to prepare for the next down receiving.
