The needle head feeding device of the prefilled syringe needle loading device has the advantages that after the injection needles are loaded in the charging barrel 27 in use, in the initial state, the needle dropping groove 29 is positioned in the charging barrel 27, the injection needles in the charging barrel 27 fall into the needle dropping groove 29, the pushing piece 28 is driven by the pushing piece 210 to stretch out, the needle dropping groove 29 stretches out of the charging barrel 27, so that the injection needles in the charging barrel 27 are pushed out, after the injection needles are pushed out, the needle taking mechanism 26 is used for taking the injection needles in the needle dropping groove 29, after the needle taking, the pushing piece 28 is driven by the pushing piece 210 to retract, the needle dropping groove 29 is retracted into the charging barrel 27, then the injection needles in the charging barrel 27 continue to fall into the needle dropping groove 29, and then the pushing piece 28 is driven by the pushing piece 210 to stretch out, so that the injection needles in the charging barrel 27 are pushed out of the charging barrel 27 one by one, the injection needles are convenient to load.
And because of the arrangement of the second rotating platform 22, the front needle feeding mechanism 24 and the rear needle feeding mechanism 25, after the injection needles in the charging basket 27 of the front needle feeding mechanism 24 are all fed, the second rotating platform 22 drives the needle feeding mounting plate 23 to rotate 180 degrees, the rear needle feeding mechanism 25 is rotated to the front side to continue feeding, and workers can place the injection needles into the empty charging basket 27 at the rear side, so that the machine is not required to stop for waiting for feeding of the empty charging basket 27, and the production efficiency of the machine can be improved.
The setting of sloping block 211 and inclined plane is convenient for the syringe needle in storage bucket 27 to slide to fall in the needle groove 29, if the ejector pad upper surface does not have sloping block 211 and inclined plane, because the ejector pad upper surface is horizontal, the syringe needle of storage bucket 27 bottom can be difficult to the horizontal migration to fall in the needle groove 29 under the promotion of no external effect, has the syringe needle of storage bucket 27 bottom also can fall into in the needle groove 29 under the direction effect of inclined plane after the setting of inclined plane and sloping block 211 to avoid the syringe needle of storage bucket 27 bottom to rest in storage bucket 27.
Since the inclined block 211 and the inclined surface 212 have a certain acting force on the injection needle in the barrel 27 when the push block is extended or retracted, the inclined surface and the inclined block 211 move forwards when the push block 28 is extended, the inclined surface and the inclined block 211 push the injection needle in the barrel 27 upwards, the injection needle in the barrel 27 moves upwards by a small extent, the injection needle in the barrel 27 moves downwards by a small extent when the push block 28 is retracted, the movement extent of the injection needle is related to the inclination angle of the inclined surface, in addition, the sliding speed of the injection needle on the inclined surface is related to the inclination angle of the inclined surface, if the inclination angle of the inclined surface is too large, the movement extent of the injection needle is large, the abrasion among the injection needles is increased, if the inclination angle of the inclined surface is too small, the sliding speed of the injection needle is small when the injection needle slides down along the inclined surface, and the friction force between the injection needle and the inclined surface is also increased, so that the movement extent of the injection needle is small when the push block 28 extends and retracts is 5 DEG to 10 DEG, the movement of the injection needle is almost small, the abrasion of the injection needle is satisfied, and the injection needle can fall from the inclined surface 29 to the injection groove is not fast, and the abrasion is not satisfied, and the abrasion is not fast.
