[0029] The working principle of the roller automatic adjustment biomass pellet machine provided by the present invention is as follows: When in use, the motor 3 is started, and the motor 3 drives the connecting cylinder 22 to rotate through the reducer 4, the connecting cylinder 22 drives the main die roller 10 and the discharge cylinder 24 to rotate, the discharge cylinder 24 drives the sleeve 23 to rotate, the main die roller 10 drives the two pressing rollers 11 to rotate, and then the raw materials for preparing granules are put into the connecting box 20 through the side hole or the top of the feed box 14, and at this time, the raw materials are granulated with the rotation of the main die roller 10 and the pressing roller 11; During the granulation process: the raw materials are kneaded by the multiple granulation grooves on the main die roller 10 and the multiple granulation grooves on the pressing roller 11 to granulate.

The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
