When the down raw materials need to be pretreated, the controller 7025 adjusts the positive and negative pressure fan 7042 to the negative pressure state, which sucks air into the air guide hood 7041 through the connecting pipe 7043, and then starts the first motor 804, which drives the third single-row synchronous pulley 806 to rotate through the drive shaft 805, and the third single-row synchronous pulley 806 drives the second double-row synchronous pulley 802 to rotate through the drive synchronous belt 807, and the second double-row synchronous pulley 802 can drive the second single-row synchronous pulley 801 to rotate through the transmission synchronous belt 803.

Then the down raw materials enter between the two rolling mills 602, and the two rolling mills 602 rotating in reverse can crush the slag and debris contained in the down raw materials, and can also crush and separate the debris adhered to part of the down, facilitating subsequent sorting and filtering. The down raw materials after rolling treatment fall onto the poking roller 7032 below, and the hooks 7033 on the poking roller 7032 can roll up and down to stir the down, facilitating the separation of dust and impurities mixed in the gap between the down. At the same time, the upper elastic block 7034 on the poking roller 7032 will intermittently hit the lower elastic block 7015 during rotation, causing it to vibrate after being stressed, which facilitates the dust and impurities accumulated above the filter plate 7014 to fall down, and then passes through the fixed filter plate 7012 for filtering. Then the air guide hood 7041 below absorbs the impurities and debris. When the set dust removal time is reached, the two electric telescopic rods 7023 are started to pull the mounting frame 7011 to rotate until it abuts against the air guide hood 7041. At this time, the proximity switch 7024 cannot detect the mounting frame 7011, and the controller 7025 controls the positive and negative pressure fan 7042 to blow air into the air guide hood 7041, which can blow the down on the filter assembly 701 into the sorting box 2, completing the impurity removal work.

The drive assembly (8) includes a first motor (804), which is connected to the corresponding first rotating shaft (601) and the corresponding second rotating shaft (7031) via a second belt drive.

7. A down sorting and filtering machine according to claim 1, characterized in that: The air separation component (3) includes a conveying pipe (301) installed on the sorting box (2), an air injection pipe (302) installed on one side of the sorting box (2), a side support bracket (303) fixedly connected to one side of the sorting box (2), a sorting fan (304) installed on the side support bracket (303), and a bend pipe (305) installed at the air outlet end of the sorting fan (304), one end of the bend pipe (305) extending into the air injection pipe (302).

8. A down sorting and filtering machine according to claim 1, characterized in that: The stirring mechanism includes a filter plate (9) installed inside the sorting box (2), a central main shaft (10) is rotatably connected to the filter plate (9), a plurality of main stirring paddles (11) are fixedly sleeved on the central main shaft (10), four side auxiliary shafts (12) are rotatably connected to the filter plate (9), and a plurality of auxiliary stirring paddles (13) are fixedly sleeved on each of the four side auxiliary shafts (12). A mounting box (14) is provided at the bottom of the sorting box (2), and a transmission component is provided inside the mounting box (14).

9. A down sorting and filtering machine according to claim 1, characterized in that: The sorting box (2) has a first maintenance door (22) on one side, and the processing box (4) has a second maintenance door (23) on one side.

10. A down sorting and filtering machine according to any one of claims 1-9, characterized in that: The sorting method of the down sorting and filtering machine includes the following steps: S1: The down enters the down sorting machine through the feeding hopper (5) and is crushed by the crushing component (6) to crush the slag and debris contained in the down raw material and separate it from the down. S2: The crushed down falls into the separation mechanism (7). The agitator (703) agitates the down, so that the light down and heavy impurities are separated. The impurities pass through the filter assembly (701) and are sucked away by the pressure control assembly (704). Then the filter assembly (701) is opened and the down enters the sorting box (2). S3: After the down enters the sorting box (2), the stirring mechanism can fully stir the down, and then the air separation component (3) is used to air separate the down.
