Description

Technical Field

[0001] This utility model relates to the field of down technology, specifically a down fluffing device. Background Technology

[0002] In down processing, "loft" is a key indicator for measuring down quality and warmth retention. The higher the loft, the better the warmth, elasticity, and comfort of the down. The loft of down comes from its unique structure: down fibers branch radially, forming countless tiny air pockets. These air pockets can lock in air and reduce heat loss.

[0003] In existing down fluffing devices, the stirring rod is mostly a fixed structure with a single movement trajectory. During the stirring process, down fibers are easily attached to the surface of the stirring rod due to friction and adsorption. As the processing time increases, the entangled down will gradually accumulate, which will not only reduce the effective contact area between the stirring rod and the down and reduce the stirring and dispersion effect, but also lead to a decrease in the uniformity of down fluffing. Therefore, a down fluffing device is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a down fluffing device that solves the problems of fixed structures and simple movement trajectories of stirring rods. During the stirring process, down fibers tend to adhere to the surface of the stirring rod due to friction and adsorption. Furthermore, as the processing time increases, the entangled down gradually accumulates, which not only reduces the effective contact area between the stirring rod and the down, but also reduces the stirring and dispersion effect, leading to a decrease in the uniformity of down fluffing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a processing tank and a support fixedly installed on the outer wall of the processing tank, and the processing tank is provided with a stirring mechanism and an air blowing mechanism inside;

[0008] The outer wall of the processing tank is fixedly provided with an inlet pipe and an outlet pipe, and two valves are fixedly provided through the outer wall of the inlet pipe and the outlet pipe respectively.

[0009] The mixing mechanism includes a mixing section and a cleaning section;

[0010] The mixing section includes a rotating tube and two sets of mixing rods, and the cleaning section includes an extrusion ring and two extrusion plates;

[0011] The rotating tube is located inside the processing tank. Two connecting frames are fixedly installed on the outer wall of the rotating tube. Two movable plates are slidably installed on the inner side of the two connecting frames. The outer walls of the two movable plates are fixedly connected to the outer walls of the two sets of stirring rods. The outer walls of the two sets of stirring rods slide through the inner side of the two connecting frames and extend to the outer side of the two connecting frames.

[0012] Preferably, the blowing mechanism includes a connecting pipe and two blowing frames. The outer wall of the connecting pipe is fixedly connected to the inner side of the rotating pipe. The outer walls of the two blowing frames extend sequentially through the outer wall of the rotating pipe and the outer wall of the connecting pipe to the inner side of the connecting pipe. A connecting box is fixedly provided on the inner side of the treatment tank. A fixing pipe is fixedly provided through the outer wall of the connecting box and extends to the inner side of the connecting box. The inner side of the fixing pipe is rotatably connected to the outer wall of the connecting pipe. The blowing mechanism enables the gas to act evenly on every part of the down in the treatment tank, and to fully contact the down after stirring and dispersing to further disperse the fibers and enhance the fluffy effect.

[0013] Preferably, two sets of springs and two sets of dampers are fixedly installed on the inner sides of the two connecting frames respectively. The outer walls of the two sets of springs and the two sets of dampers are fixedly connected to the outer walls of the two moving plates respectively. The initial state of the two sets of springs is a compressed state. Through the springs and dampers, the two sets of stirring rods are contracted inward.

[0014] Preferably, a servo motor is fixedly installed on the outer wall of the processing tank. The output end of the servo motor extends through the outer wall of the processing tank to the inner side of the processing tank. The outer wall of the output end of the servo motor is fixedly connected to the outer wall of the rotating tube. When the servo motor is started, its output end drives the rotating tube to rotate inside the processing tank.

[0015] Preferably, the outer wall of the extrusion ring is fixedly connected to the inner side of the processing tank, and the outer walls of the two connecting frames are respectively provided with two sliding grooves. The inner walls of the two sliding grooves are respectively slidably connected to the outer walls of the two extrusion plates. The outer walls of the two extrusion plates are respectively fixedly connected to the outer walls of the two moving plates. The side of the two extrusion plates away from the two moving plates is correspondingly arranged with the extrusion ring. When the extrusion plate contacts the extrusion ring, the extrusion ring generates a thrust on the extrusion plate, forcing the extrusion plate to slide along the sliding groove on the connecting frame, thereby driving the two moving plates and the two sets of stirring rods to move away from the rotating tube.

[0016] Preferably, an air pump is fixedly installed on the outer wall of the treatment tank. The air pump outlet extends through the outer wall of the treatment tank and the outer wall of the connecting box to the inner side of the connecting box. An annular groove is opened on the inner side of the fixed pipe. A limit ring is slidably installed on the inner wall of the annular groove.

When the air pump is started, gas is sent into the interior of the connecting box through the air outlet.

[0017] (III) Beneficial Effects

[0018] This invention provides a down fluffing device. It has the following beneficial effects:

[0019] (i) The down fluffing device of this invention uses a mechanical combination of a squeezing ring and a squeezing plate to make the stirring rod periodically extend and retract during rotation. This design can not only change the stirring range to adapt to the down distribution in different areas of the processing tank, effectively break up the piled down clumps and avoid excessive fiber entanglement, improve the fluffing uniformity, and lay the foundation for subsequent processing; it can also use the sliding connection between the stirring rod and the connecting frame during extension and retraction to peel off the down entangled on the surface, reducing the frequency of manual cleaning and maintenance costs.

[0020] (ii) In this down fluffing device, the air blowing frame in the air blowing mechanism rotates synchronously with the rotating tube, which enables the gas to act evenly on every part of the down in the processing tank, avoiding the problem of uneven fluffing caused by the traditional fixed air blowing method. It can fully contact the down after stirring and dispersing to further disperse the fibers and enhance the fluffing effect. At the same time, the relative rotation of the connecting tube and the fixed tube is achieved by the sliding cooperation between the limiting ring and the inner ring groove of the fixed tube. While ensuring stable gas delivery when the rotating tube rotates, it does not interfere with the operation of the stirring mechanism. It runs synchronously with the stirring mechanism to form a synergistic effect and improve the overall processing efficiency. Attached Figure Description

The outer walls of the two sets of springs 37 and two sets of dampers 38 are fixedly connected to the outer walls of the two movable plates 35. The two sets of springs 37 initially... All are in a compressed state. A servo motor 31 is fixedly installed on the outer wall of the processing tank 1. The output end of the servo motor 31 extends through the outer wall of the processing tank 1 to the inner side of the processing tank 1. The outer wall of the output end of the servo motor 31 is fixedly connected to the outer wall of the rotating tube 34. The outer wall of the extrusion ring 32 is fixedly connected to the inner side of the processing tank 1. Two sliding grooves are respectively opened on the outer walls of the two connecting frames 39. The inner walls of the two sliding grooves are slidably connected to the outer walls of the two extrusion plates 33. The outer walls of the two extrusion plates 33 are fixedly connected to the outer walls of the two moving plates 35. The side of the two extrusion plates 33 away from the two moving plates 35 is respectively set to correspond to the extrusion ring 32.

[0033] The air blowing mechanism 5 includes a connecting pipe 51 and two air blowing frames 52. The outer wall of the connecting pipe 51 is fixedly connected to the inner side of the rotating pipe 34. The outer walls of the two air blowing frames 52 extend through the outer walls of the rotating pipe 34 and the connecting pipe 51 to the inner side of the connecting pipe 51. A connecting box 56 is fixedly installed on the inner side of the treatment tank 1. A fixing pipe 55 is fixedly installed through the outer wall of the connecting box 56 and extends to the inner side of the connecting box 56. The inner side of the fixing pipe 55 is rotatably connected to the outer wall of the connecting pipe 51. An air pump 54 is fixedly installed on the outer wall of the treatment tank 1. The air outlet of the air pump 54 extends through the outer wall of the treatment tank 1 and the outer wall of the connecting box 56 to the inner side of the connecting box 56. An annular groove is opened on the inner side of the fixing pipe 55. A limit ring 53 is slidably installed on the inner wall of the annular groove. The inner side of the limit ring 53 is fixedly connected to the outer wall of the connecting pipe 51.

[0034] When in use, the down is fluffed up through the coordinated operation of the stirring mechanism 3 and the blowing mechanism 5;

[0035] Before the device is started, the valves on the feed pipe 4 and the discharge pipe 6 are closed. When processing down, first open the valve on the feed pipe 4 to send the down to be processed into the processing tank 1 through the feed pipe 4. After feeding is completed, close the valve on the feed pipe 4.

[0036] When the servo motor 31 in the stirring mechanism 3 is started, its output end drives the rotating tube 34 to rotate inside the processing tank 1. When the rotating tube 34 rotates, it drives the moving plate 35 and the two sets of stirring rods 36 to rotate synchronously through the connecting frame 39. The stirring rods 36 stir the down in the processing tank 1, so that the down can be dispersed. During rotation, the extrusion plate 33 on the connecting frame 39 will contact the extrusion ring 32 fixed on the inner side of the processing tank 1. When the extrusion plate 33 contacts the extrusion ring 32, the extrusion ring 32 will exert a pushing force on the extrusion plate 33, forcing the extrusion plate 33 to slide along the slide groove on the connecting frame 39, thereby driving the two moving plates 35 and the two sets of stirring rods 36 to move away from the rotating tube 34. After the two extrusion plates 33 are separated from the extrusion ring 32, the two sets of stirring rods 36 will retract inward through the spring 37 and the damper 38. This periodic extension and retraction movement of the stirring rods 36 can more fully stir the down, avoid down accumulation, enhance the stirring effect, and the periodic extension and retraction movement of the stirring rods 36 can clean the down wrapped on the surface.

[0037] Simultaneously, the air blowing mechanism 5 operates synchronously, and the air pump 54 starts, sending gas through the air outlet into the connecting box 56. The gas in the connecting box 56 enters the fixed pipe 55. Because the annular groove on the inner side of the fixed pipe 55 slides in conjunction with the limiting ring 53 on the outer wall of the connecting pipe 51, and the connecting pipe 51 is fixedly connected to the rotating pipe 34, the connecting pipe 51 can rotate freely relative to the fixed pipe 55 when the rotating pipe 34 rotates, ensuring that the gas can stably enter the connecting pipe 51 from the fixed pipe 55. The gas entering the connecting pipe 51 is ejected through the air blowing frame 52 that passes through the rotating pipe 34 and the connecting pipe 51. After being ejected from the air blowing frame 52, the gas acts on the down in the treatment tank 1, performing air blowing and fluffing treatment on the down. The ejected gas comes into full contact with the down in the stirring process, further dispersing the down fibers and making the down fluffier.

[0038] After processing, the servo motor 31 and air pump 54 are turned off, and the valve of the discharge pipe 6 is opened. The processed down is discharged from the processing tank 1 through the discharge pipe 6, completing the entire down fluffing process.
