The working principle of the separation discharging device 100 of the present application will be described in detail with reference to the accompanying drawings:

firstly, the stacked sheet materials are placed and loaded in the material storage rack 20, the rear side of the bottom of the stacked sheet materials can be loaded on the vibration bearing plate 352, the vibration motor 353 drives the vibration bearing plate 352 to vibrate, the sheet materials on the vibration bearing plate 352 can be vibrated to fall into complete contact with the bearing surface of the first friction conveyor belt 34, the first rotary driver 33 drives the second rotary shaft 32 to rotate clockwise (the direction indicated by arrow A in fig. 4), the second rotary shaft 32 can drive the first friction conveyor belt 34 to drive clockwise, and the first friction conveyor belt 34 can drive one sheet material positioned at the lowest part in the material storage rack 20 to output and feed outwards from the discharge hole 24 through friction force.

Meanwhile, the second rotary driver 44 drives the third rotary shaft 45 to drive the return material friction roller 46 to rotate clockwise along the direction indicated by the arrow A in FIG. 4, if the top of the single Zhang Pianzhuang material output by the forward feeding mechanism 30 is sticky with one or more sheet materials, the return material friction roller 46 can drive the sheet materials sticky with the top of the single Zhang Pianzhuang material output by the forward feeding mechanism 30 to return into the storage rack 20 by virtue of the friction force or pushing force between the return material friction roller 46 and the sheet materials sticky with the top of the single Zhang Pianzhuang material because the distance between the return material friction roller 46 and the first friction conveyor 34 is smaller than the thickness of two sheet materials.

The single sheet material enters the conveying channel between the second friction conveyor belt 54 and the bottom of the driven pressing roller 553 after passing through the output gap 47, the third rotary driver 53 drives the fifth rotary shaft 52 to rotate clockwise (in the direction indicated by arrow a in fig. 4), the fifth rotary shaft 52 can drive the second friction conveyor belt 54 to drive clockwise, the bearing surface of the second friction conveyor belt 54 rubs against the bottom of the sheet material, and the second friction conveyor belt 54 can drive the sheet material to be conveyed to the receiving bearing plate 61 by friction force. And, the number of sheet materials conveyed through the forward conveying mechanism 50 is detected by the number detection sensor 80.

When the receiving carrier plate 61 receives a single sheet material, the first linear driver 62 drives the rear positioning push plate 63 to push the rear side of the sheet material so as to push the sheet material to move forward, so that the front side of the sheet material moves to abut against the front limiting plate 611; meanwhile, the second linear driver 64 drives the left positioning push plate 65 to push the sheet material to the left so as to push the sheet material to move rightwards, so that the right side of the sheet material moves to abut against the right limiting plate 612; thereby completing the positioning operation of the sheet material in the butt stock carrier 61.

If the thickness detection sensor 71 detects that the sheet material conveyed on the forward conveying mechanism 50 is a double sheet material, after the double sheet material falls into the receiving carrier plate 61, the third linear driver 72 may drive the rejecting push plate 73 to drive the push arm 731 to push the double sheet material on the receiving carrier plate 61 back into the recovery tank 74, so as to automatically reject the double sheet material on the receiving carrier plate 61.

Alternatively, the separation and discharge device 100 of the present application may be selectively applied to a filling and sealing film device for nucleic acid extracting solution, that is, the sheet materials separated one by one and output one by one in the present application may be selected as a sheet paper film sealed and adhered on an opening of a reagent card strip, and of course, specific application of the separation and discharge device 100 of the present application is not limited thereto, and those skilled in the art may flexibly select according to actual use requirements, so that detailed descriptions thereof are omitted herein.

Because the forward feeding mechanism 30 and the reverse feeding mechanism 40 of the separating and discharging device 100 are both arranged on the frame 10, the forward feeding mechanism 30 drives the sheet materials positioned at the lowest position in the stacked sheet materials to be output outwards, the reverse feeding mechanism 40 is positioned above the output end of the forward feeding mechanism 30, and the reverse feeding mechanism 40 drives the sheet materials adhered to the top of the single Zhang Pianzhuang material output by the forward feeding mechanism 30 to be conveyed along the direction opposite to the output direction of the forward feeding mechanism 30. If the top of the single Zhang Pianzhuang material output by the forward feeding mechanism 30 is sticky with one or more sheet materials, the reverse feeding mechanism 40 can drive the sheet materials sticky with the top of the single Zhang Pianzhuang material output by the forward feeding mechanism 30 to be conveyed along the direction opposite to the output direction of the forward feeding mechanism 30, so that the forward feeding mechanism 30 is guaranteed to output only the single Zhang Pianzhuang material, and the separation operation of the sheet materials is completed. The structure is simpler, the separation speed is greatly increased, the sheet-shaped material stuck on the top of the single Zhang Pianzhuang material output by the forward feeding mechanism 30 can be driven to be reversely conveyed by the reverse feeding mechanism 40, and the occurrence probability of the double-tensioning condition is greatly reduced. And then ensure that the sheet material of single seals the subsides and puts for the sheet material seals and pastes firmly, ensures sealed effect, avoids the condition of weeping to take place, better guarantee encapsulation effect.
