Embodiment

[0012] Such as figure 1 , shown in Fig. 2, Fig. 3, a kind of new-type disposable injection needle loading machine described in this embodiment comprises a needle taking plate 3, a needle groove 4 and a needle falling groove 5, and an electromagnetic needle is provided on the needle taking plate 3. Iron pull-in device 7, described electromagnet pull-in device 7 is mainly made up of electromagnet bar 1, electromagnetic coil 8 and capacitor 10, and capacitor 10 is connected in parallel with electromagnetic coil 8 through positive and negative conversion switch 9. When the needle-taking plate 3 tops a needle tube 2 from the needle groove 4, the electromagnet strip 1 is energized to generate a magnetic field to immediately attract the needle tube 2, and then the electromagnet strip 1 is pushed to the needle drop groove 5 by the cylinder 6, thus When disconnecting the power supply and utilizing the reverse discharge of the capacitor 7 to demagnetize the needle tube 2, the needle tub...
