Example 1

Referring to fig. 4 to 11, the feeding mechanism 2 is more preferably used in the present embodiment in addition to the above.

The material pipe carrying assembly 22 comprises a carrying cylinder 220 fixedly connected to the bottom surface of the horizontal substrate 10, a feeding connecting block 221 fixedly connected to an output rod of the carrying cylinder 220, an L-shaped rotating rod 222 with a first end 2220 rotatably connected to the feeding connecting block 221, a connecting rod 224 slidably connected to a second end 2221 of the L-shaped rotating rod, and pipe clamping blocks 225 fixedly connected to two ends of the connecting rod 224, wherein the middle part of the L-shaped rotating rod 222 is rotatably connected to the bottom surface of the horizontal substrate 10; the connecting rod 224 and the pipe clamping blocks 225 at both ends thereof constitute a material shuttle 223 for loading the material pipe 6.

The material tube 6 in the rack 20 can fall down onto the tube clamping block 225, and the conveying cylinder 220 drives the tube clamping block 225 to move along the Y direction through the L-shaped rotating rod 222 so as to convey the material tube 6 loaded on the tube clamping block 225 along the Y direction.

Wherein, the rack 20 is provided with a storage trough 200 for allowing the material pipe 6 to be stacked and contained in the Z-direction. The material rest 20 comprises two symmetrically arranged material tubes 6, the material tubes 6 are sequentially placed in the material storage tank 200 in a single row, and the material tubes 6 can fall freely and fall onto the pipe clamping blocks 225 through the openings in the bottoms.

Namely, a gap is left between the tube blocking plate 201 and the tube clamping block 225, but the gap does not allow the tube 6 to pass through. When the tube clamping block 225 carries the bottommost tube 6 along the Y axis, the tube baffle 201 can block the tube 6 above, so that the tube 6 above is prevented from moving along with the bottommost tube 6, and only one tube 6 is carried at a time.
