[0029] Working principle:

[0030] According to the size of the pre-filled needle to be cached, use the width adjustment component to adjust the chute width of the feeding chute component 2 and the discharging chute component 3. Then, fix the position of the storage baffle 15 according to the positions of the fixed chute plate 6 and the adjustable chute plate 7 of the discharging chute component 3. Again, according to the size of the pre-filled needle to be cached, select a storage chute component 4 with a corresponding width and place it on the vertical support plate 14. Thus, the cache preparation work is completed.

During actual use, adjust and fix the positioning block 25 according to the size model of the pre-filled needle, and it can realize the quick and accurate positioning and fixing of the adjustable chute plate 7.

[0032] The shape of the storage chute is S-shaped, which can slow down the sliding speed of the pre-filled needle during the storage process and prevent the pre-filled needle from being damaged.

The material detection sensor 28 can be used to timely detect whether the pre-filled needle is blocked.

[0035] A buffer collection device applicable to a pre-filled needle of the present utility model forms a stock storage chute assembly by paralleling multiple stock storage chutes with widths adapted to the same pre-filled needle model.
