Next, under the action of the swing cylinder 11, the horizontal mechanism rotates clockwise 90 ° around the horizontal rotation shaft 122 until the horizontal bottom plate 18 is limited by the first positioning stop nut 118, in the specific limiting process, the horizontal bottom plate 18 slowly presses down the head of the first positioning stop nut 118 until the head is fully retracted into the nut, the horizontal bottom plate 18 is limited by the nut to stop moving, and at this time, the horizontal mechanism is in a horizontal feeding state. After the infusion apparatus is taken away by the material taking assembly of the material taking and shifting mechanism 2, the horizontal placing mechanism is driven by the swing cylinder 11 to rotate anticlockwise for 90 degrees and reset around the horizontal rotating shaft 122, the vertical limiting block 121 is also driven to rotate together until the vertical limiting block 121 is limited by the second positioning stop nut 120, at the moment, the horizontal placing mechanism recovers the vertical state of manual material placing, and the material loading is finished.

After the material is discharged and fed, the translation cylinder 21 drives the material taking assembly of the material taking and moving mechanism 2 to move to the position right above the material feeding mechanism, then the material taking cylinder 22 drives the first clamping device to descend, when the first clamping device descends to a certain position, the front clamping jaw cylinder 210 drives the front air jaw support 212 to be opened, so that the two front air jaws 213 are separated, the right rear clamping jaw 214 and the left rear clamping jaw 215 are also separated, and the rear clamping jaw cylinder 211 drives the two air pipe clamping jaws 216 to be opened. When the first clamping device descends to a certain position, the front clamping jaw cylinder 210 and the rear clamping jaw cylinder 211 drive the first clamping device to fold and clamp the infusion set, at the moment, the puncture outfit of the infusion set is positioned in the puncture outfit fixing block 2131 of the front air jaw 213, the catheter end part is positioned in the catheter fixing block formed by the matching of the left rear clamping jaw 215 and the right rear clamping jaw 214, and the middle part of the catheter is clamped in the tracheal clamping jaw 216. After the infusion apparatus is clamped, the material taking cylinder 22 drives the first clamping device to ascend and reset, the translation cylinder 21 drives the material taking assembly to move to the position right above the tube winding mechanism 3, and then the material taking cylinder 22 drives the first clamping device to descend.
