the base 5 is provided with a receiving cavity on the side close to the compaction plate 1303, the limiting plate 1305 is welded on the side away from the guide seat 1301 of the collecting box 1210, and the limiting strip 1304 and the limiting plate 1305 can guide the stable vertical movement of the compaction plate 1303; the first rotating column 1106 and the second rotating column 1110 are rotatably connected with the main body 1 of the down cluster separating machine, and the pushing inclined plate 1202 is slidably connected with the main body 1 of the down cluster separating machine.

[0032] In specific implementation, during the use of the down cluster separating machine capable of removing impurities, when the down with light quality has been blown to the bottom of the second screen 4 for adsorption, and only down feather and impurities are left on the top of the first screen 3, the servo motor 1101 is started to drive the fixed gear 1102 to rotate, the fixed gear 1102 is in meshing connection with the rack 1103, the rotation of the fixed gear 1102 generates a pushing force on the rack 1103, so that the rack 1103 moves horizontally along the slide rail 1104, the rack 1103 is guided by the slide rail 1104 to move stably, the rack 1103 is in meshing connection with the transmission gear 1105, the movement of the rack 1103 drives the transmission gear 1105 to rotate, then the rotation of the transmission gear 1105 drives the first rotating column 1106 to rotate, the electromagnet 1112 in the supporting seat 1113 is closed in advance, the electromagnet 1112 is no longer in magnetic attraction connection with the iron fixed disc 1111, and then the limiting of the first synchronous wheel 1107 and the second synchronous wheel 1109 is cancelled, so that the first synchronous wheel 1107 and the second synchronous wheel 1109 can rotate.

[0033] Because the outer wall of the first rotating column 1106 is connected with the first synchronous wheel 1107, the rotation of the first rotating column 1106 will drive the first synchronous wheel 1107 to rotate, then the rotation of the first synchronous wheel 1107 drives the second synchronous wheel 1109 to rotate through the synchronous belt 1108, then the rotation of the second synchronous wheel 1109 drives the first synchronous wheel 1107 to rotate, and because the middle part of the first rotating column 1106 is connected with the first mesh screen 3 and the middle part of the second rotating column 1110 is connected with the second mesh screen 4, at this time, the first rotating column 1106 and the second rotating column 1110 rotate simultaneously, which drives the first mesh screen 3 and the second mesh screen 4 to rotate, until the first mesh screen 3 and the second mesh screen 4 are in a horizontal state, at this time, the side of the first mesh screen 3 attached with the feather and impurities faces downward, and the side of the second mesh screen 4 attached with the down of lighter quality faces upward, then the electromagnetic iron 1112 is started to be magnetically connected with the iron fixed disc 1111, so as to limit the first mesh screen 3 and the second mesh screen 4 from continuing to rotate, then the second air blower 8 is started to suck the down of lighter quality out of the main body 1 of the down separating machine through the cooperation of the blowing pipe 7 and the suction pipe 9, so as to complete the removal of impurities;

[0034] When the horizontal movement of the rack 1103 causes the teeth at the top of the rack 1103 to be disconnected from the transmission gear 1105, the horizontal movement of the rack 1103 will not drive the transmission gear 1105 to rotate, then when the rack 1103 moves and contacts the transmission seat 1204, a pushing force will be generated on the transmission seat 1204 to make it move along the limiting column 1207 to the direction of approaching the support plate 1208, at this time, the transmission seat 1204 is guided by the limiting column 1207 to move horizontally stably, and the movement of the transmission seat 1204 will extrude the spring 1209 to cause it to deform, then the spring 1209 is reset to assist the transmission seat 1204 to return to the original position, so that the auxiliary mechanism 11 can cooperate with the material taking mechanism 12;

[0035] The fixed column 1203 is connected with the blocking plate 1205 on one side of the bottom of the transmission seat 1204, and the transmission seat 1204 moves to drive the fixed column 1203 and the blocking plate 1205 to move together. At this time, the discharge port 1206 will appear with the movement of the blocking plate 1205. Because the fixed column 1203 is connected with the pushing plate 1202, the movement of the fixed column 1203 drives the pushing plate 1202 to move together. Then, the movement of the pushing plate 1202 drives the rubber scraping plate 1201 to move together. At this time, with the movement of the rubber scraping plate 1201, the vanes and impurities at the bottom of the first mesh 3 are scraped off and fall into the inner wall at the bottom of the down cluster separating machine main body 1. Then, with the horizontal movement of the pushing plate 1202, the fallen vanes and impurities are pushed by the pushing plate 1202 to fall into the collection box 1210 through the discharge port 1206, thereby collecting impurities and vanes, and without moving the first mesh 3 and the second mesh 4 out of the down cluster separating machine main body 1, the qualified down on the first mesh 3 and the impurities on the second mesh 4 can be taken out, avoiding frequent disassembly of the mesh which is easy to cause mechanical part wear and tear, and without workers frequently carrying heavy mesh components, reducing physical exertion and the risk of operation errors, thereby avoiding physical damage to qualified down such as fiber breakage by reducing operation steps, and the mesh is always in a closed body, which can prevent external dust and moisture from invading and contaminating down to improve sorting accuracy, and can prevent residual down and impurities from being mixed again due to disassembly disturbance.

[0036] When the impurities and vanes fall into the collection box 1210, they first fall onto the guide seat 1301, and then are guided to the other side of the collection box 1210 through the inclined surface of the outer wall of the guide seat 1301. Because the transmission seat 1204 is rotationally connected with the rotating plate 1302, when the rack 1103 in the auxiliary mechanism 11 moves to push the transmission seat 1204 in the taking mechanism 12 to move, the transmission seat 1204 drives the rotating plate 1302 in the compacting mechanism 13 to rotate.

[0037] At this time, the angle between the rotating plate 1302 and the transmission seat 1204 changes, thereby generating a downward pushing force on the compacting plate 1303, so that the compacting plate 1303 moves downward along the limiting strip 1304. When the compacting plate 1303 moves into the collection box 1210, it is guided by the limiting plate 1305, thereby moving downward stably. Then, the downward movement of the compacting plate 1303 generates pressure on the impurities and vanes in the collection box 1210, so that they are compacted to reduce the occupied space. After the impurities and vanes are compacted, the risk of moisture absorption and oxidation can be reduced, which is suitable for long-term storage, thereby reducing transportation and storage costs.

[0038] In summary, the impurity-removable down feather separating machine uses the base 5 placed in the designated position in the factory building in advance, then the down feather to be treated is introduced into the down feather separating machine body 1 through the feeding pipe 2 and falls on the top of the first screen 3, then the first fan 6 and the second fan 8 are started, then the first fan 6 cooperates with the blowing pipe 7 to blow the first screen 3, and then the down feather with lighter quality is blown to the second screen 4 for adsorption, at this time the feather and impurities are still on the top of the first screen 3, then the qualified down feather and impurities are screened out, and at this time the second fan 8 cooperates with the suction pipe 9 to suck the second screen 4, so as to cooperate with the down feather with lighter quality to move upward, which is the prior art and will not be described in detail here. The auxiliary mechanism 11 makes the side of the first screen 3 attached with the feather and impurities face downward, and the side of the second screen 4 attached with the down feather with lighter quality face upward, then the auxiliary mechanism 11 drives the material taking mechanism 12 to work, so that the impurities fall into the collecting box 1210 for centralized collection, then the qualified down feather and impurities can be taken out without removing the first screen 3 and the second screen 4, which avoids frequent disassembly of the screen to cause part wear, then reduces the physical damage to the qualified down feather, and can prevent the residual down feather and impurities from being mixed again due to disassembly disturbance, so as to improve the separation precision. The contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0039] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
