Description

Technical Field

[0001] The utility model relates to the technical field of down processing, in particular to a down feeding system. Background Art

[0002] Down is by far the best natural material for human warmth. After undergoing pre-selection, dust removal, washing, drying, and grading, it is made into down jackets. Compared to man-made materials, down offers three times the warmth. During the down processing process, dust removal directly impacts the final down quality. During the down production process, recycled down is often contaminated with debris, such as gravel, iron filings, and clods of earth. Traditionally, the recycled down is poured directly into a cleaning tank for cleaning before further processing. However, the presence of this debris compromises the effectiveness of cleaning and other treatments, directly impacting the quality of the down.

[0003] Therefore, the patent application number CN201520052518.X discloses a feeding device for down processing. The feeding box is driven to vibrate by a vibration motor. Although the heavier debris in the down can be shaken out, the vibration separation method is likely to affect the stability of the device. In addition, there may be some larger and harder dust in the down debris. Due to the light weight of these dusts, it is difficult to separate them by vibration. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a down feeding system that can separate heavier debris from recycled down without vibrating, and can also effectively separate larger and harder dust from down debris.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A down feeding system comprises a feed inlet, a first air supply device, a debris removal trough, a second air supply device, a dust removal passage and a discharge port; the input end of the first air supply device is connected to the feed inlet, and the output end of the first air supply device is connected to the debris removal trough; the opening of the debris removal trough has a height difference from high to low along the air supply direction of the first air supply device; the input end of the second air supply device is connected to the debris removal trough; one end of the dust removal passage is connected to the output end of the second air supply device, and the other end of the dust removal passage is connected to the discharge port; the dust removal passage is spiral-shaped, and the side wall outside the dust removal passage is a mesh structure.

[0007] As an optional solution, the dust removal channel is vertically arranged, the upper end of the dust removal channel is connected to the output end of the second air supply device, and the lower end of the dust removal channel is connected to the discharge port.

[0008] As an optional solution, the first air supply device includes a first transfer box and is connected to a first fan; the upper end of the first transfer box is the input end, one side of the first transfer box is connected to the first fan, and the other side of the first transfer box is the output end.

[0009] As an optional solution, the second air supply device includes a second transfer box and a second fan; one side of the second transfer box is the input end, the upper end of the second transfer box is connected to the second fan, and the lower end of the second transfer box is the output end.

[0010] As an optional solution, the inner bottom wall of the impurity removal tank is rotatably provided with an impeller.

[0011] Due to the adoption of the above technical solution, the utility model will have the following beneficial effects:

[0012] The utility model provides a down feeding system, which provides a debris removal trough with a height difference from high to low along the air supply direction of a first air supply device, so that the recovered down passing through the debris removal trough will make a parabolic motion. During this process, heavier debris will fall into the debris removal trough due to a faster falling speed, while lighter down will continue to be blown forward due to a slower falling speed, thereby separating the heavier debris in the recovered down; and by providing a spiral dust removal channel with a mesh structure on the outer side wall, the down accelerated by the second fan is allowed to advance in a spiral manner through the dust removal channel, and then the larger and harder dust in the down is subjected to the action of centrifugal force and wind force in the process of spiral advancement, and is separated from the dust removal channel through the mesh structure, thereby effectively separating the larger and harder dust in the down debris. Compared with the vibration separation method of the existing down processing feeding device, the utility model can separate the heavier debris and the larger and harder dust in the recycled down without vibration, which provides convenience for the subsequent processing of the down.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0020] Please refer to Figure 1 and Figure 2In one embodiment of a down feeding system of the present invention, the down feeding system includes a feed port 1, a first air supply device 2, a debris removal trough 3, a second air supply device 4, a dust removal channel 5 and a discharge port 6; wherein the feed port 1 is used to receive recycled down, which is not only mixed with a lot of heavy debris, such as gravel, iron filings, soil blocks, etc., but also contains some large and hard dust; the input end of the first air supply device 2 is connected to the feed port 1, and the output end of the first air supply device 2 is connected to the debris removal trough 3, and the recycled down can be blown to the debris removal trough 3 through the first air supply device 2; the opening of the debris removal trough 3 is along the first air supply device The air supply direction has a height difference from high to low, so that heavier debris falls into the debris removal trough 3, while lighter down continues to be blown forward; the input end of the second air supply device 4 is connected to the debris removal trough 3, and one end of the dust removal channel 5 is connected to the output end of the second air supply device 4. The down after the heavier debris is removed can be blown into the dust removal channel 5 through the second air supply device 4; the other end of the dust removal channel 5 is connected to the discharge port 6. The dust removal channel 5 is spiral-shaped so that the blown down is blown forward in a spiral manner. The outer side wall of the dust removal channel 5 has a mesh structure so that larger and harder dust in the down debris can be separated from the dust removal channel 5 under the centrifugal force.

[0021] Specifically, due to the existence of the mesh structure on the dust removal channel 5, part of the output wind will escape from the mesh structure, and thus the second air supply device 4 needs a larger wind output to be able to blow the down along the dust removal channel 5 to the discharge port 6; based on this, the dust removal channel 5 can be set vertically, the upper end of the dust removal channel 5 is connected to the output end of the second air supply device 4, and the lower end of the dust removal channel 5 is connected to the discharge port 6, so that the second air supply device 4 does not need to overcome gravity to blow, thereby reducing the load of the second air supply device 4.

[0022] Specifically, the first air supply device 2 includes a first transfer box 21 and a first fan 22; the upper end of the first transfer box 21 is the input end, one side of the first transfer box 21 is connected to the first fan 22, and the other side of the first transfer box 21 is the output end. The recycled down first enters the first transfer box 21 from the top, and then is blown horizontally to the impurity removal trough 3 by the first fan 22.

[0023] Specifically, the second air supply device 4 includes a second transfer box 41 and a second fan 42; one side of the second transfer box 41 is the input end, the upper end of the second transfer box 41 is connected to the second fan 42, and the lower end of the second transfer box 41 is the output end. The down passing through the impurity removal trough 3 first enters the second transfer box 41 horizontally, and then is accelerated by the second fan 42 to be blown to the dust removal channel 5.

[0024] Based on the above embodiment, considering that some down may accidentally fall into the debris removal tank 3, a pulsator 31 is rotatably connected to the inner bottom wall of the debris removal tank 3. The pulsator 31 adopts the structural design of a disc-shaped rotating wheel with ribs on the bottom of the drum of an existing pulsator 31-type washing machine. The pulsator 31 is coaxially connected to a drive motor (not shown) and is driven by the drive motor. When the pulsator 31 rotates, it generates an upward airflow. Combined with the heavy debris shaken up and down by the rotation of the pulsator 31, it can push the lighter down upward, causing it to continue to move forward under the action of the wind from the first air supply device 2.

[0025] The usage method or working principle of the utility model is as follows:

[0026] The recycled down first enters the first transfer box 21 from the feed inlet 1 from above, and is then blown horizontally to the impurity removal trough 3 by the first fan 22. After the down comes out of the first transfer box 21, since the opening of the impurity removal trough 3 has a height difference from high to low along the air supply direction of the first air supply device 2, the recycled down passing through the impurity removal trough 3 will make a parabolic motion. In this process, heavier impurities will fall into the impurity removal trough 3 due to their faster falling speed, while lighter down will continue to be blown forward due to their slower falling speed; the down that continues to move forward first enters the second transfer box 41 horizontally, and is then accelerated by the second fan 42 to be blown to the dust removal channel 5, and is blown forward in a spiral from top to bottom from the upper end of the dust removal channel 5, and finally output from the discharge port 6 to feed the subsequent down processing. The larger and harder dust in the down will be affected by the centrifugal force and wind force during the spiral blowing process and leave the dust removal channel 5 through the mesh structure.

[0027] It should be clear that the wind force of the first fan is set to at least blow the down over the dust removal trough, and the wind force cannot be too strong to prevent heavy debris in the down from being blown over the dust removal trough along with the down; the wind force of the second fan is set to at least accelerate the down to be blown through the dust removal channel and output from the discharge port; the aperture of the mesh structure on the dust removal channel is set to allow larger and harder dust in the down to pass through and limit the down itself from passing through.

[0028] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
