The expansion device 225 may select an expansion sleeve or key (shown in FIG. 2 as an expansion sleeve). The end surfaces of the second and third shaft sleeves 222 and 223 are provided with mutually matching positioning steps 226.

The connection pipe 23 is located inside the coupling 22, and both ends of the connection pipe 23 are connected to the output shaft 211 of the motor 21 and the roller 4, respectively.

Steps are formed on the outer peripheral surfaces of the two ends of the connecting pipe 23, and the two steps respectively abut against the end surface of the output shaft 211 of the motor 21 and the end surface of the roller body 24, so that the connecting pipe 23 is prevented from moving along the axial direction. Sealing rings 231 are arranged between the connecting pipe 23 and the output shaft 211 of the motor 21 and between the connecting pipe 23 and the roller body 24, so that the sealing performance between the connecting pipe and the output shaft 211 of the motor 21 and the roller body 24 can be improved, and glue leakage is prevented.

A glue spraying pipe 25 communicated with the connecting pipe 23 is arranged in the roller body 24. The output shaft 211 of the motor 21, the connecting pipe 23 and the glue spraying pipe in the roller body 24 form a glue passage of the centrifugal roller assembly 2.
