A lipstick tube sorting method, based on a lipstick tube sorting device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, feeding: lipstick tubes (101) are put into the feeding hopper (11) from the upper end, and the lipstick tubes (101) are arranged one by one through the first dividing plate (111) in the feeding hopper (11) and fall onto the conveyor belt (12), and are conveyed into the sorting rack (23) at the first position through the conveyor belt (12). The detection head (132) arranged in the feeding device can count the number of lipstick tubes (101) entering the sorting rack (23). When the number of lipstick tubes (101) in the sorting rack (23) reaches a maximum, the first driving device (133) is controlled to extend the pressing block (134) to fix the lipstick tubes (101) on the transfer plate (131), and the conveyor belt (12) is stopped at the same time; S2, sorting: the receiving device (4) is raised by the third driving device (43), so that the upper end opening of the receiving bucket (41) of the receiving device (4) corresponds to the separation groove (2311) of the sorting plate (231), and the pushing frame (33) is driven to approach the sorting frame (23) by starting the second driving device (32), and the pushing rod (331) of the pushing frame (33) pushes the lipstick tube (101) with the small diameter end (102) in the sorting frame (23) facing the pushing rod (331) from the separation groove (2311) into the receiving bucket (41), and the lipstick tube (101) in the receiving bucket (41) falls into the receiving frame (42), and the fourth driving device (51) drives the movable frame (52) to move, and the first pushing plate (53) pushes the lipstick tube (101) in the receiving frame (42) outward; S3, transposition: the receiving device (4) is lowered through the third driving device (43), so that the receiving bucket (41) leaves the rotation range of the sorting frame (23), and the central shaft (21) is rotated to rotate the sorting frame (23) in the first position to the second position, and the receiving device (4) is raised through the third driving device (43), so that the upper end opening of the receiving bucket (41) of the receiving device (4) corresponds to the separation groove (2311) of the sorting plate (231), and the pushing frame (33) is driven to approach the sorting frame (23) by starting the second driving device (32), and the pushing plate is pushed. The push rod (331) pushes the lipstick tube (101) with the small diameter end (102) in the sorting rack (23) toward the push rod (331) from the separation groove (2311) into the receiving bucket (41), and the lipstick tube (101) in the receiving bucket (41) falls into the receiving rack (42). The fourth driving device (51) drives the movable rack (52) to move, and the first pushing plate (53) and the second pushing plate (54) can simultaneously push the lipstick tube (101) in the receiving rack (42) and the lipstick tube (101) in the sorting rack (23) at the second position outward.
