Description

Technical Field

[0001] The invention belongs to the technical field of down production, and in particular relates to a production device for hydrophobic down that does not contain fluorocarbon compounds. Background Art

[0002] Hydrophobic molecules tend to be non-polar and therefore are more soluble in neutral and non-polar solutions. Hydrophobic molecules usually clump together in water, and water forms a large contact angle and forms a droplet shape when it is on the surface of a hydrophobic solution.

[0003] By subjecting the surface of natural down to special treatment to form a hydrophobic film, the surface of the down has a lasting water-repellent ability. The down treated in this way is called hydrophobic down.

[0004] In the production process of hydrophobic down, the down needs to be soaked. The soaked down is easy to clump when drying, which makes the drying of the down uneven, thus affecting the drying efficiency of the down. Uneven drying will also affect the quality of the down. Summary of the invention

[0008] Preferably, the rubbing mechanism comprises a rotating drum arranged on a bracket, and the rotating drum is provided with more than two rubbing plates along its circumference.

[0009] Preferably, the filter screen is provided with a circular ring, the rotating drum is provided with a driven wheel which rotates concentrically therewith, and the circular ring is used to drive the driven wheel to rotate.

[0010] Preferably, the washboard is an arc-shaped structure and is made of elastic material.

[0012] Preferably, the second plate is provided with serrations at one end away from the rotating drum.

[0013] The beneficial effects of the present invention are:

[0014] The present invention can drive the down to do centrifugal motion, thereby throwing out a large amount of water in the down. The down is rubbed during its rotation, which can effectively reduce the agglomeration of the down, thereby improving the drying efficiency of the down and avoiding the problem of uneven down quality due to uneven drying.

[0020] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1-4 As shown, a production equipment for hydrophobic down that does not contain fluorocarbon compounds includes a supporting leg 1, a box body 2, a filter screen 3 arranged in the box body 2 for placing down, a driving motor 4 for driving the filter screen 3 to rotate, an air intake duct 5 for air intake, a bracket 6 arranged on the inner wall of the box body 2, a rubbing mechanism arranged on the bracket 6 for rubbing the down, and an air outlet pipe 7 arranged on the box body 2 for exhausting and discharging the down.

[0023] As a further solution of the present invention, the rubbing mechanism includes a rotating drum 8 arranged on the bracket 6, and more than two rubbing plates are arranged on the rotating drum 8 along its circumference.

[0024] In the above embodiment, the reserved placement door on the box 2 is opened, the wet down is placed on the filter 3, and the placement door is closed. Hot air is introduced from the air inlet pipe 5, and the hot air is discharged from the outlet pipe 7 after passing through the filter 3. The drive motor 4 is started, and the drive motor 4 drives the filter 3 to rotate, so that the down on the filter 3 performs centrifugal motion. Under the action of centrifugal force, a large amount of water absorbed by the down is thrown out, falls from the filter 3 to the bottom of the box 2, and leaks out from the water outlet at the bottom of the box 2. At the same time, the filter 3 drives the down to rotate so that the rubbing mechanism contacts the down. In the process of the rubbing plate of the rubbing mechanism contacting the down, the unity of the down is broken up, and the flat structure of the down becomes more three-dimensional during the rubbing process, which helps the hot air to dry the down. When the down is dried, its weight becomes lighter, and it is lifted upward under the action of the hot air. When the hot air is discharged from the outlet pipe 7, it also brings out the dry down, and the down discharged from the outlet pipe 7 can be collected.

[0025] As a further solution of the present invention, a circular ring 9 is provided on the filter screen 3, and a driven wheel 10 rotating concentrically therewith is provided on the rotating drum 8, and the circular ring 9 is used to drive the driven wheel 10 to rotate.

[0026] As a further solution of the present invention, the washboard is an arc-shaped structure and is made of elastic material.

[0027] In the above embodiment, the filter screen 3 drives the ring 9 to rotate when rotating, and the ring 9 drives the driven wheel 10 to rotate by contacting with the driven wheel 10, thereby driving the rotating drum 8 and the rubbing board to rotate in the opposite direction to the movement of the down. The rubbing board will decompress the down during the rotation process, and rub the down on the inner wall of the filter screen 3, thereby effectively reducing the aggregation of the down. Active rubbing produces a better effect than passive rubbing, thereby accelerating the drying of the down.

[0028] As a further solution of the present invention, the rubbing board includes a No. 1 plate 11 and a No. 2 plate 12 which are hinged to each other. The No. 2 plate 12 intermittently contacts the filter 3 under the drive of the rotating drum 8. The No. 1 plate 11 is provided with an electromagnet 14, and the No. 2 plate 12 is provided with an iron block 15 which cooperates with the electromagnet 14 and is used to drive the No. 2 plate 12 to rotate. A reset spring 13 is provided between the No. 1 plate 11 and the No. 2 plate 12 to drive the No. 2 plate 12 to reset.

[0029] As a further solution of the present invention, the second plate 12 is provided with serrations at one end away from the rotating drum 8 .

[0030] In the above embodiment, when the washboard is in contact with the filter screen 3, it bends and deforms, and the reset spring 13 is subjected to tension. When the washboard is about to recover its deformation, the electromagnet 14 is activated, attracting the iron block 15, so that the second plate 12 rotates instantly. The rotation of the second plate 12 drives the down on the filter screen 3 to move upward, thus producing the effect of scattering the down. On the one hand, it can reduce the cohesion of the down, and on the other hand, it can make the down fully dry in the airflow. The serrated second plate 12 can smoothly carry a large amount of down. At this time, the reset spring 13 and the electromagnet 14 are respectively located on both sides of the washboard.

[0031] In addition, the return spring 13 and the electromagnet 14 can be arranged on the same side of the washboard. In this case, the return spring 13 is subjected to the extrusion force of the second plate 12 and the first plate 11 when the washboard is squeezed, and other conditions are the same.

[0032] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
