The first driving member 120 is transmission-connected to the blocking plate 100, and the first driving member 120 can drive the blocking plate 100 to move along the extension direction of the picking hole 110 to selectively block the feeding channel.

[0034] That is, an embodiment of the utility model provides a venous needle feeding device, in which a material blocking mechanism 10 is arranged between a material dividing mechanism 20 and a material picking mechanism, and the material blocking mechanism 10 includes a material blocking plate 100 and a first driving member 120; a material picking hole 110 is arranged on the material blocking plate 100, and a plurality of material picking holes 110 are arranged one-to-one corresponding to a material dividing channel, and the first driving member 120 is transmission-connected with the material blocking plate 100, and the first driving member 120 can drive the material blocking plate 100 to move along the extension direction of the material picking hole 110 to selectively block the material dividing channel; the movement of the material blocking plate 100 driven by the first driving member 120 is used to adjust the relative position of the material picking hole 110 and the material dividing channel, so that after the material picking mechanism grabs the first venous needle, the subsequent venous needles can be blocked by the material blocking plate 100, so as to solve the problem of multiple venous needles adhering to each other and discharging in the prior art, resulting in uneven venous needle feeding, and improve the stability of venous needle feeding.

The transmission frame 420 is rectangular as a whole, and the second stopper needles are evenly fixed to the bottom of the transmission frame 420 by bolts along the arrangement direction of the material distribution channels.
