[0052] A round tube feeding device, the specific implementation of which is as follows:

[0053] One side of the inclined discharge portion 3 in the feeding device of the present application is close to the production line to be fed.

[0054] Initially, the first driving part 5 controls the inclined material discharge part 3 to rotate upward to be higher than the plane support part 2 , and the push plate 4 moves to a position away from the inclined material discharge part 3 .

[0055] A number of round tubes 0 are placed on the plane support part 2 between the push plate 4 and the inclined blanking part 3 as a storage rack for the round tubes 0, wherein the round tubes 0 are clamped between the push plate 4 and the inclined blanking part 3, and the round tubes 0 in contact with the inclined blanking part 3 are the round tubes to be loaded.

[0056] When the round tube 0 needs to be loaded onto the corresponding production line, the first driving unit 5 first controls the inclined discharge part 3 to rotate downward until it is flush with the plane support part 2, and then the second driving unit drives the push plate 4 to move forward a distance of the round tube diameter, so that the round tube to be loaded moves to the inclined discharge part 3, and then the first driving unit 5 controls the inclined discharge part 3 to rotate downward, so that the round tube located on the inclined discharge part 3 falls along the slope to the production line.

[0057] Afterwards, the first driving unit 5 controls the inclined blanking unit 3 to rotate upward and reset, thereby achieving the blocking operation on the round tube again.
