Description

Technical Field

[0001] The invention relates to the technical field of down processing, and in particular to a down fluffing device for processing down jackets and a down fluffing method thereof. Background Art

[0002] Down jackets are a common type of warm clothing, and their thermal insulation performance mainly depends on the fluffiness of the down. The higher the fluffiness of the down, the better its thermal insulation performance. However, after being collected, the down usually undergoes pre-processing steps such as cleaning, disinfection, and sorting, which makes it easy to be compressed during processing, resulting in a decrease in fluffiness and affecting the thermal insulation performance of the final product.

[0003] Existing down fluffing devices mainly use mechanical stirring or air flow impact to fluff up the down to improve the fluffiness of the down. The mechanical stirring method mainly stirs the down through a stirring rod, but the rotation of the stirring rod can easily damage the down fibers, thereby reducing the fluffiness and warmth retention of the down. In addition, it is also difficult to control the stirring speed. Too low a speed will result in poor fluffiness of the down, while too high a speed will aggravate the damage to the down fibers. The air flow impact method is to blow the down by injecting high-speed airflow into the down. Although it can effectively fluff up the down, the airflow control is not precise enough, which can easily lead to uneven distribution of the down, thus affecting the overall quality of the down jacket.

[0004] Therefore, the present application designs a down fluffing device and a down fluffing method for down jacket processing to solve the above-mentioned technical problems. Summary of the invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] A Chinese patent with the patent number CN202322540846.1 discloses a down fluffing device, which includes a down processing box. On the outer wall of the top right of the down processing box, a feed inlet is fixedly installed. On the bottom left of the down processing box, a discharge outlet is fixedly installed. On the outer wall of the other end of the feed inlet, an electric gate valve one is fixedly installed. On the outer wall of the other end of the discharge outlet, an electric gate valve two is fixedly installed. At the bottom of the down processing box, an air pump one is fixedly installed. On the outer wall of the top and the inner wall of the bottom of the down processing box, filter nets are fixedly installed. The filter net located at the bottom inner wall of the down processing box is directly above the output port of the air pump one. On the outer wall of the bottom right of the down processing box, a fixed frame is fixedly installed. At the four corners of the top of the down processing box, heating tubes are fixedly installed. At the end of the discharge outlet far from the down processing box, a hair suction pump is fixedly installed. The outer wall of the fixed frame is fixedly connected to the outer wall of the air pump two. The air pump one, the air pump two, the hair suction pump, the heating tubes, the electric gate valve one and the electric gate valve two are all general standard parts or components known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or through conventional experimental methods. When processing, the feed inlet needs to be connected to the down conveying equipment in the whole set of down processing production line, and the down is conveyed into the down processing box through this equipment for processing. After the down is conveyed into the down processing box, the electric gate valve one and the electric gate valve two are closed, and then the air pump one is started to make the air pump one blow upward, so that the stacked down randomly flutters in the down processing box. As shown in the figure, there is a through hole on the top of the down processing box, and the gas generated during processing will be discharged from this through hole. At the same time, as shown in the figure, a filter net is arranged on this through hole, and the mesh diameter of the filter net is smaller than the area of the down, so as to prevent the down from flying out of the down processing box through the filter net. After the down in the down processing box flutters for a certain period of time, the heating tubes are started to generate a certain amount of heat through the heating tubes, so that the temperature in the down processing box rises. In this way, the down can absorb heat and expand and contract, so that the down gradually becomes fluffy;

[0038] There are four electric hydraulic rods. The output ends of the four electric hydraulic rods are fixedly connected to the four corners at the bottom of the moving plate. There are four electric telescopic rods. The four electric telescopic rods are respectively fixedly connected to the left and right sides of the inner wall of the moving plate. There are two moving blocks. The two moving blocks are respectively slidably connected to the left and right sides of the inner wall of the moving plate. The outer walls of the opposite sides of the two moving blocks are respectively fixedly connected to the outer walls of the output ends of the four electric telescopic rods. After finishing the down processing work, start the electric hydraulic rods to push the moving plate downward. The outer wall of the moving plate is in contact with the inner wall of the down processing box and the outer wall of the heating tubes. In this way, the down on the upper components can be pushed downward to compress the placement space of the down;

[0039] The movable plate here is as shown in the figure, with a hole in the middle. The diameter of this hole is the same as that of the hole opened at the top of the down processing box. When the movable plate is located at the top inner wall of the down processing box, the electric telescopic rod will drive the movable block to move away from the hole. When the movable plate moves downward, the electric telescopic rod will drive the movable block to block the hole;

[0040] The output end of the air pump II is fixedly connected to the outer wall of one end of the connecting pipe. The outer wall of the other end of the connecting pipe is fixedly connected to the outer wall of the connecting sleeve. The outer wall of the other side of the connecting sleeve is fixedly connected to the top inner wall on the right side of the down processing box. When finishing the down processing work, start the air pump II. The air pump II generates wind and blows air into the down processing box through the connecting pipe and the connecting sleeve. The blowing direction of the air pump II is towards the discharge port. In this way, it will drive the down to move towards the discharge port. The down here has already had its space compressed by the movable plate. When the air pump II blows the down, the down will not fly randomly. At this time, start the hair suction pump. The hair suction pump will generate suction to suck out the down in the discharge port, so as to transport the down out of the down processing box;

[0041] The outer wall of the down processing box is connected with a blowing device. The blowing device includes: air pump II, connecting pipe, connecting sleeve. The blowing device is used to blow the down to move in the same direction. The top of the down processing box is connected with a pressing device. The pressing device includes: electric hydraulic rod, movable plate, electric telescopic rod, movable block. The pressing device is used to compress the moving space of the down.

[0042] The use process of this patent is as follows: During processing, connect the feed port to the down conveying equipment in the whole set of down processing production line, and convey the down into the down processing box through this equipment. When the down is conveyed into the down processing box, close the electric gate valve I and the electric gate valve II, and then start the air pump I, so that the air pump I blows upward, so that the stacked down randomly flies in the down processing box. After the down in the down processing box has flown for a certain period of time, start the heating pipe. The heating pipe generates a certain amount of heat, so that the temperature in the down processing box rises. In this way, the down can absorb heat and expand and contract due to heat, so that the down gradually becomes fluffy. After finishing the down processing work, start the electric hydraulic rod to push the movable plate downward. The outer wall of the movable plate is in mutual contact with the inner wall of the down processing box and the outer wall of the heating pipe. In this way, the down on the upper components can be pushed downward to compress the placement space of the down. Then start the air pump II. The air pump II generates wind and blows air into the down processing box through the connecting pipe and the connecting sleeve, driving the down to move towards the discharge port. Then start the hair suction pump. The hair suction pump will generate suction to suck out the down in the discharge port, so as to transport the down out of the down processing box.

[0043] However, during the fluffing process of the down in this solution, the down is only impacted by air flow to make it fluffy, but the fluffing effect and efficiency of the down are relatively low; at the same time, when the down is discharged, there is a tendency for the down to remain.

[0044] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] In an embodiment of the present application, since the mounting holes 32 are evenly distributed and the airflows in adjacent mounting holes 32 interfere with each other, the airflow becomes more variable, improving the impact effect.

[0057] For a further optimized solution, a blocking cap 34 is installed at one end of the mounting hole 32 facing the inner cylinder 22. An air outlet 35 is provided on the blocking cap 34.

[0068] The present invention also discloses a fluffing method based on a fluffing device for processing down jackets, comprising the following steps:

[0069] Prepare the pre-treated down and then feed it into the inner cavity of the fluffing cylinder 2; feed the down that has undergone pre-treatment steps such as cleaning, disinfection, and sorting from the connecting pipe 23 into the cavity of the inner cylinder 22 until the set processing amount is reached, and then disconnect the connecting hole from the outside;

[0070] Introduce clean gas into the pressure equalizing chamber 3 and conduct air exchange in the pressure equalizing chamber 3 for a period of time; introduce clean gas into the pressure equalizing chamber 3 through an external gas source and maintain it for a period of time, so that the clean gas discharges the original gas in the pressure equalizing chamber 3, avoiding the contamination of the down by the original gas and ensuring the cleanliness of the fluffing of the down;

[0071] After the pressure in the pressure equalizing chamber 3 reaches the set value, maintain the pressure in the pressure equalizing chamber 3 stable; monitor the pressure in the pressure equalizing chamber 3 through the pressure sensor 39, and maintain a constant pressure after reaching the index to ensure the stability during the subsequent air flow impact on the down;

[0072] Start the air flow impact head 31 to inflate the inner cavity of the inner cylinder 22, and impact the down in the inner cavity of the inner cylinder 22 with clean gas; start the micro fan 33 and the electric push rod to make a gap for the gas to flow out between the adjusting ball 36 and the air outlet, and then pump the clean gas into the inner cavity of the inner cylinder 22 at a certain flow rate through the micro fan 33 and impact it on the down, causing the down to spread and fluff; at the same time, during the fluffing process, make the electric push rod extend and retract according to a certain rule to adjust the air flow speed and flow rate of the air outlet, improving the efficiency of the impact on the down;

[0073] Start the driving assembly to drive the fluffing cylinder 2 to rotate at a set speed for a set time to make the down reach the set fluffing state; start the driving motor 14 to drive the fluffing cylinder 2 to rotate at a set speed, cooperating with the air flow impact and rotation to improve the fluffing effect on the down and improve the fluffing efficiency;

[0074] Discharge the fluffed down to facilitate subsequent processing; after reaching the fluffing time, start the telescopic rod 113 to make the fluffing cylinder 2 tilt towards the discharge direction, the down moves towards the lower end, and at the same time start the hair suction pump at the outlet end of the rod to discharge the down, facilitating subsequent processing.

[0075] For a further optimized solution, when discharging the fluffed eiderdown, the fluffing cylinder 2 is in a rotating state, and the air curtain formed by the air flow ejected from the air flow impact head 31 pushes the eiderdown towards the outlet of the fluffing cylinder 2. When discharging, the air flow impact head 31 is gradually closed from the high end to the low end, and the air flow ejected from the air outlet opened at the topmost end forms an air curtain to prevent the eiderdown from floating towards the high end, and through gradual downward pressure, the eiderdown can be discharged quickly and thoroughly, reducing the residue and loss of the eiderdown, and improving the utilization rate and production efficiency of the eiderdown.
