Sequence of mechanical actions of the whole device:
the initial state of the invention is as follows: the limiting slide block 15 is positioned in the limiting slide cavity 13, the compression spring 11 is in a compression state, the pull rope 12 is in a release state, the extension spring 47 is in a release state, the extrusion spring 23 is in a release state, the reset spring 18 is in a release state, the connecting spring 53 is in a compression state, the trapezoidal push plate 54 is positioned in the push cavity 52, and the extension spring 56 is in a release state;
1. when the quantitative screening method is used for quantitatively screening medicines, the medicines are placed on the upper surface of the screening sliding plate 16, the screening sliding plate 16 slides downwards due to the weight of the medicines, and if the weight of the medicines is insufficient, the screening sliding plate 16 or the sliding plate 14 always extrudes the limiting sliding block 15, so that the limiting sliding block 15 is positioned in the limiting sliding cavity 13;
2. if the weight of the medicine is in the qualified range, the sieving sliding plate 16 slides downwards until the sieving sliding plate 16 stops extruding the limiting slide block 15 and is positioned in the abutting joint of the driven extruding block 19 with the sliding plate 14, the compression spring 11 resets to drive the limiting slide block 15 to slide rightwards, the limiting slide block 15 slides rightwards to strain the pull rope 12, the pull rope 12 is strained to pull the vertical slide block 46 to slide upwards, the vertical slide block 46 slides upwards to stretch the extension spring 47, the vertical slide block 46 slides upwards to drive the driving rotating shaft 26 to slide upwards, the driving rotating shaft 26 slides upwards to drive the driving gear 25 and the driving bevel gear 27 to slide upwards, when the vertical slide block 46 slides upwards to abut against the upper cavity wall of the vertical sliding cavity 45, the driving gear 25 is engaged with the driven gear 43, the driving bevel gear 27 is engaged with the linkage bevel gear 35, the motor 29 is started to drive the, the linkage bevel gear 35 rotates to drive the driving bevel gear 27 to rotate, the driving bevel gear 27 rotates to drive the driving rotating shaft 26 to rotate, the driving rotating shaft 26 rotates to drive the driving gear 25 to rotate, the driving gear 25 rotates to drive the driven gear 43 to rotate, the driven gear 43 rotates to drive the power rotating shaft 44 to rotate, the power rotating shaft 44 rotates to drive the power bevel gear 39 to rotate, the power bevel gear 39 rotates to drive the driven bevel gear 37 to rotate, the driven bevel gear 37 rotates to drive the driven rotating shaft 36 to rotate, because the driven rotating shaft 36 is in transmission connection with the linkage rotating shaft 48 through the transmission belt pulley 49, the driven rotating shaft 36 rotates to drive the linkage rotating shaft 48 to rotate, the linkage rotating shaft 48 rotates to drive the sector gear 40 to rotate, the sector gear 40 rotates to drive the rack 42 to slide backwards, the rack 42 slides backwards to stretch the extension spring 41 and drive the push, the sieving is finished, because the qualified range of the medicines has certain weight fluctuation, when the sieving sliding plate 16 is positioned at some positions at the lower side of the push plate 51, the connecting spring 53 is reset to drive the trapezoidal push plate 54 to slide downwards, and the medicines are pushed into the collection cavity 21 through the trapezoidal push plate 54;
3. when the linkage rotating shaft 48 rotates to the state that the sector gear 40 is disengaged from the rack 42, the extension spring 41 resets to drive the rack 42 to slide forwards, the rack 42 slides forwards to drive the push plate 51 to slide forwards, the push plate 51 slides forwards to accommodate the trapezoidal push plate 54 into the push cavity 52, and the connecting spring 53 is compressed, because after the medicine is pushed into the collection cavity 21, the return spring 18 resets to drive the sieving slide plate 16 to slide upwards to the initial position, and the limiting slide block 15 is squeezed again to slide leftwards into the limiting slide cavity 13;
4. if the medicine is too heavy and the sifting slide plate 16 slides downwards until the driving extrusion block 17 abuts against the driven extrusion block 19, the driving extrusion block 17 extrudes the driven extrusion block 19 to slide forwards, the driven extrusion block 19 slides forwards to drive the driving slide block 20 to slide forwards, the driving slide block 20 slides forwards to compress the extrusion spring 23 and drive the slide push rod 24 to slide forwards, the slide push rod 24 slides forwards to drive the driven slide block 28 to slide forwards, the driven slide block 28 slides forwards to drive the motor shaft 62 to slide forwards, the motor shaft 62 slides forwards to drive the linkage bevel gear 35 to slide forwards to disengage the linkage bevel gear 35 from the driving bevel gear 27, and to engage the linkage bevel gear 35 with the engagement bevel gear 32, the linkage bevel gear 35 rotates to drive the engagement bevel gear 32 to rotate, the engagement bevel gear 32 rotates to drive the sliding rotating shaft 57 to rotate, and the sliding rotating shaft 57 rotates to, the rotating shaft 60 rotates and swings the knocking block 31, the knocking block 31 is swung to stretch the extension spring 33 and knock the vibrating plate 34, so that the fact that a worker is overweight with the medicine is avoided, the worker is prevented from waiting for medicine screening for a long time, and working efficiency is affected, if too much medicine is overweight and the driven slider 28 slides forwards for too long distance, the linkage bevel gear 35 slides forwards to drive the matching bevel gear 32 to slide forwards, the matching bevel gear 32 slides forwards to drive the sliding rotating shaft 57 to slide forwards, the sliding rotating shaft 57 slides forwards to drive the T-shaped rotating block 59 to slide forwards, and the T-shaped rotating block 59 slides forwards to compress the telescopic spring 56, so that the matching bevel gear 32 and the linkage bevel gear 35 are always kept meshed;
5. the invention can screen out the part with unqualified weight in the medicine, ensures the effectiveness and safety of the medicine, can package the medicine in the next step after the screening is finished, and restores the initial state.
