[0031] See also Figure 1 to Figure 4A high-loft down jacket filling device comprises a filling machine body 1 and a filling tube 2 arranged on the filling machine body 1, the filling device further comprises a cylindrical elastic air bag 7 located on the filling tube 2, which is used to close the filling port of the down fabric to be filled, and a plurality of exhaust channels 13 are circumferentially arranged on the wall of the filling tube 2;

[0032] The filling device further comprises a shaking assembly 5 located below the filling tube 2, which is used to continuously shake the down fabric during filling.

[0033] The operator puts the down fabric onto the filling tube 2 (the end of the filling tube 2 away from the filling machine body 1 first penetrates into the bottom of the down fabric. During filling, the down fabric is pulled in the direction away from the filling tube 2, and the down is filled in sequence from the bottom of the down fabric to the filling port). The filling port of the down fabric is closed by inflating the cylindrical elastic airbag 7 to prevent down from escaping. Then the filling machine body 1 is started. The airflow generated during filling makes the down fabric swell. The shaking component 5 is used to keep the swollen down fabric in a continuous shaking state, so that the down is evenly and fluffy distributed, and the down filling is completed and the fluffiness meets the standard. There is no need for subsequent patting operations, which is both trouble-free and labor-saving.

[0034] It should be noted that one end of the exhaust channel 13 is close to the down outlet hole 9 (air inlet) and is always located inside the down fabric when filling with down.

When filling, the two-way air pump 3 is used to inject air into the cylindrical elastic air bag 7 so that its expanded air bag wall is tightly against the filling port of the down fabric, thereby closing the filling port, and when the down fabric is pulled, the elastic effect of the cylindrical elastic air bag 7 can always keep the filling port closed; after the filling is completed, the two-way air pump 3 is used to extract the gas in the cylindrical elastic air bag 7 to make it deflate and reset to carry out the next down fabric filling operation.

[0036] See also Figure 1 , Figure 5 and Figure 6In one embodiment of the present invention, the shaking component 5 includes a material table 501 arranged on the filling machine body 1 and a mounting member 502 arranged in the material table 501, the material table 501 is located below the filling tube 2, and an open groove 505 vertically opposite to the filling tube 2 is provided on the material table 501, and a plurality of elastic bars 506 are evenly arranged in the open groove 505, and vertical poles 503 corresponding to the plurality of elastic bars 506 are provided on the mounting member 502, and a knocking ball 504 is provided on the upper end of each of the vertical poles 503, and the mounting member 502 can move reciprocatingly up and down to drive the knocking ball 504 to cyclically knock the elastic bar 506.

[0037] In this embodiment, when filling, the down fabric is placed on multiple elastic bars 506, and the mounting part 502 moves back and forth up and down to drive the striking ball 504 to cyclically strike the elastic bars 506. After being struck, the elastic bars 506 are in a shaking state and then drive the down fabric to shake, making the down fluffy and evenly distributed.

[0038] Furthermore, in this embodiment, the spring bar 506 is made of spring steel material, and the knocking ball 504 is preferably made of rubber material.

[0039] See also Figure 1 , Figure 6 and Figure 7 In one embodiment of the present invention, the filling device further includes a driving mechanism 6 for realizing the reciprocating movement of the mounting member 502 up and down, the driving mechanism 6 includes a plurality of guide rods 605 arranged in the material platform 501, the lower ends of the guide rods 605 penetrate the mounting member 502 and are provided with a lower limit block 607, the material platform 501 is provided with an electromagnet 603, and the mounting member 502 is provided with a magnetic member 604 corresponding to the electromagnet 603;

[0040] The material table 501 is provided with a rotatable shaft 608, and a magnetic separator 609 is provided on the shaft 608.

[0043] In the present embodiment, when filling with down, the airflow discharged from the inside of the down fabric is gathered in the air collecting piece 602, and then discharged through the air guide pipe 601 to blow toward the blade 610, thereby driving the rotating shaft 608 to rotate. The rotation of the rotating shaft 608 drives the partition disk 609. When the partition disk 609 rotates to the through groove 611 and is aligned with the electromagnet 603 and the magnetic part 604, the electromagnet 603 in the energized state magnetically attracts the magnetic part 604 and then drives the mounting part 502 to move up to the set position, thereby driving the knocking ball 504 to knock the elastic bar 506. When the partition disk 609 rotates to the through groove 611 and is misaligned with the electromagnet 603 and the magnetic part 604, the partition disk 609 blocks the magnetic attraction, and the mounting part 502 moves down and resets under the action of gravity, and this cycle is repeated to drive the mounting part 502 to move back and forth up and down.
