A needle tube guide plate is provided at the bottom of the through groove. The needle tube guide plate has a wedge-shaped guide side, and the guide side and an inner side of the through groove form a wedge-shaped needle tube guide groove.

[0008] In a further preferred embodiment, a horizontally positioned movable baffle is provided at the outlet position of the needle guide groove, and a second needle cylinder is provided on the corresponding needle support, with the piston rod of the second needle cylinder connected to the movable baffle.

[0009] The advantages and beneficial effects of this utility model are as follows: when the needle tubes are piled up in the needle tube trough, the needle tubes near the groove of the roller shaft fall into the groove and rotate with the needle tube roller shaft to the top of the through groove of the needle tube support plate. Then, they fall into the needle tube guide groove through the through groove of the needle tube support plate. In the needle tube guide groove, the needle tube changes from a horizontal state to a vertical state and is inserted into the needle seat through the needle tube guide pressing mechanism. This realizes the function of automatic needle tube feeding and assembly, avoiding the tedious manual operation of manual loading and also avoiding the risk of injury during manual loading.
