Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of down processing, and particularly relates to a down fluffing device for down jacket processing and a fluffing method thereof. BACKGROUND

[0002] As a common warm-keeping garment, the warm-keeping performance of a down jacket mainly depends on the fluffiness of down. The higher the fluffiness of down is, the better the warm-keeping performance of the down jacket is. However, after being collected, down is usually subjected to pretreatment steps such as cleaning, disinfection and sorting, so that the down is easily compressed in the processing process, resulting in a decrease in fluffiness and affecting the warm-keeping performance of the final product.

[0003] The existing down fluffing device mainly adopts mechanical stirring or airflow impact to fluff the down, so as to improve the fluffiness of the down. The mechanical stirring mainly stirs the down through a stirring rod, but the rotation of the stirring rod is easy to cause damage to the down fibers, thereby reducing the fluffiness and warm-keeping performance of the down. In addition, the control of the stirring speed is also difficult, and too low speed will result in poor fluffing effect of the down, while too high speed will aggravate the damage to the down fibers. The airflow impact method is to blow the down by blowing high-speed airflow into the down, which can effectively fluff the down, but the control of the airflow is not accurate enough, which is easy to cause uneven distribution of the down, and further affect the overall quality of the down jacket.

[0004] Therefore, the present application designs a down fluffing device for down jacket processing and a fluffing method thereof to solve the above technical problems. SUMMARY

3. The down fluffing device for down garment processing according to claim 2, characterized in that: A sealing 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 sealing cap (34). An adjusting ball (36) for adjusting the air outlet state is movably embedded in the air outlet (35). The adjusting ball (36) is connected to the drive module (37) installed in the mounting hole (32).

4. The down fluffing device for down garment processing according to claim 1, characterized in that: The connecting pipe (23) has an annular connecting cavity (24). One end of the connecting cavity (24) is connected to the pressure equalization cavity (3) through several first connecting holes (25), and the other end of the connecting cavity (24) is connected to an external compressed air source through several second connecting holes (26) to supply the pressure equalization cavity (3) with clean gas at a stable pressure.

5. The down fluffing device for down garment processing according to claim 4, characterized in that: The connecting pipe (23) is fixedly connected to a positioning ring (27) corresponding to the second connecting hole (26). The positioning ring (27) is sealed and rotated with an air intake ring (28) that is connected to the compressed air source. The second connecting hole (26) passes through the positioning ring (27) and is connected to the inner cavity of the air intake ring (28).

6. The down fluffing device for down garment processing according to claim 1, characterized in that: The drive assembly includes a drive motor (14) mounted on the frame (1). The output shaft of the drive motor (14) is connected to a drive rod (15). Both ends of the drive rod (15) are connected to drive gears (18). The drive gears (18) mesh with a gear ring (29) sleeved on the outer cylinder (21).

7. The down fluffing device for down garment processing according to claim 6, characterized in that: The frame (1) is provided with a plurality of support blocks (111) corresponding to the gear ring (29), and the outer cylinder (21) is rotatably connected to the support blocks (111); the support blocks (111) are provided with positioning grooves (112) corresponding to the gear ring (29), and the gear ring (29) is in sliding contact with the positioning grooves (112).

8. The down fluffing device for down garment processing according to claim 7, characterized in that: One of the support blocks (111) is hinged to the frame (1), and the other support block (111) is hinged to the frame (1) with a telescopic rod (113) for support adjustment.

9. A method for fluffing down in down garment processing, based on the down fluffing device for down garment processing according to any one of claims 1-8, characterized in that... Includes the following steps: Prepare the pre-treated down and then put it into the inner cavity of the fluffing tube (2); Clean gas is introduced into the pressure equalization chamber (3) and the pressure equalization chamber (3) is ventilated for a period of time. After the pressure in the pressure equalization chamber (3) reaches the set value, the pressure in the pressure equalization chamber (3) is kept stable. Turn on the airflow impact head (31) to inflate the inner cavity of the inner cylinder (22) with air, and use the clean gas to impact the down in the inner cavity of the inner cylinder (22); The start-up drive component drives the fluffing tube (2) to rotate at a set speed and maintains the rotation for a set time, so that the down reaches the set fluffy state; The down feathers are then removed after they have become fluffy, making it easier for them to be processed later.

10. The method for fluffing down in down garment processing according to claim 9, characterized in that: When the fluffed down is discharged, the fluffing tube (2) is in a rotating state, and the airflow ejected by the airflow impact head (31) forms an air curtain that pushes the down toward the outlet of the fluffing tube (2).
