The invention has the beneficial effects that: compared with the prior art, the automatic blood taking needle packaging equipment disclosed by the invention has the following advantages:

(1) the blood taking needle taking and distance changing device with high automation degree is adopted, the device has compact structure, small occupied space and high operation efficiency, the blood taking needle can be prevented from being damaged, the distance between the blood taking needles is adjusted to be matched with the distance of subsequent winding operation equipment after the blood taking needle is stably and regularly grabbed, and the subsequent winding operation can be smoothly and rapidly carried out;

(2) the winding mechanism and the tensioning mechanism are used for clamping the blood taking needle hose, the tensioning driving mechanism is used for tensioning the blood taking needle hose, and the winding driving mechanism and the tensioning driving mechanism are matched for winding the blood taking needle, so that the whole process is high in automation degree, good in operation continuity, mechanical winding and high in working efficiency; the blood taking needle cannot be polluted in the winding process, the hose of the blood taking needle cannot be damaged, the winding quality is stable, the wound needle handle is consistent with the blood taking needle in direction and is positioned at the center of the winding mechanism, and the clamping and bagging of the blood taking needle tube in the subsequent operation are facilitated; the hose of the blood taking needle is wound on the periphery of the support body formed by the first guide pillar and the second guide pillar in a surrounding mode, after winding is finished, the winding air claw drives the first mechanical arm and the second mechanical arm to loosen the blood taking needle hose, the first guide pillar integrated with the first mechanical arm moves towards the second guide pillar at the moment, and the wound blood taking needle hose is loosened, so that the wound blood taking needle can be taken down by equipment in the subsequent operation process;

(3) the manipulator clamps the blood taking needle and can take in the storage barrel after the blood taking needle is coiled, not only can the manipulator be stably moved to the next procedure under the protection of the storage barrel, but also the blood taking needle can be effectively prevented from being coiled to rebound and loose under the limit of the storage barrel

Through the arrangement of the second direction transfer mechanism and the first direction transfer mechanism, the stability of the coiling clamping mechanism in the transfer process is greatly improved, when the coiling clamping mechanism moves to the front of an opened packaging bag, the storage barrel extends into the packaging bag through the first direction transfer mechanism, the first cylinder acts, the manipulator extends out of the storage barrel and opens, the blood taking needle coil falls into the packaging bag, and the first direction transfer mechanism drives the coiling clamping mechanism to reset so as to complete the smooth bagging of the blood taking needle coil;

(4) the bag taking lifting cylinder drives the vacuum sucker to contact with a packaging bag positioned at the lowest end of the bin through a packaging bag through hole in a bottom plate of the bin, the vacuum sucker slightly pushes up the packaging bag and then pulls down the packaging bag to be taken out from the bin smoothly, the bag taking lifting cylinder moves to a packaging bag righting mechanism through a bag taking transverse moving guide rail after being contracted, the packaging bag is placed in the packaging bag righting mechanism to be righted and adjusted, the success rate of a subsequent bag opening process is greatly improved after the packaging bag is righted, pre-opening is firstly carried out after the packaging bag is taken down, a gap is opened for the packaging bag, and then bag opening operation is carried out, so that the bag opening can be opened to a target size smoothly;

(5) structural design is reasonable, and the transfer process steadiness of wrapping bag is high: when the transfer manipulator is closed, the exhaust foam can extrude and coat the region of the packaging bag except for the sealing position, and the boundary between the coated region and the non-coated region of the packaging bag is extruded through a bag clamping silica gel strip, so that the position stability of the packaging bag containing the blood taking needle roll in the transfer manipulator is enhanced; can effectively prevent that blood taking needle book from being taken out: after the coiled blood taking needles are transferred to the packaging bag through the transfer device, the material clamping air claw acts to drive the material clamping mechanical arm to close, and material clamping foams press the packaging bag and the blood taking needle rolls in the packaging bag, so that the positions of the blood taking needle rolls are kept stable when the transfer device is drawn out of the packaging bag; can effectively extrude the air in the blood taking needle wrapping bag: when the transfer device is completely moved out of the packaging bag, the transfer gas claw acts to drive the transfer mechanical arm to be closed, the foam is exhausted to extrude the packaging bag, and the gas in the packaging bag is extruded out, so that the sealed packaging bag is prevented from being extruded and exploded;

(6) according to actual requirements, loosening nuts on the bolts, adjusting the relative positions of the height adjusting plate and the front convex plate in the vertical direction, and screwing the nuts on the bolts again, so that the relative positions of the upper pressing mechanism and the lower pressing mechanism can be flexibly adjusted according to actual requirements such as the thickness of the packaging bag; because go up pressing mechanism and adopt multi-structure demountable installation's the form that sets up, pressing mechanism's adhesive tape adopts the form that sets up of pegging graft down for it is more convenient to go up pressing mechanism, lower pressing mechanism and dismantle, maintain, change when local damage appears in the structure.
