The present invention relates to a cuttings-feeding rubber mixing technique, which belongs to the field of rubber-processing machines. The technique includes the following steps: (1) the storage of raw rubber, (2) the ripping of rubber blocks, (3) the weighing of cuttings, (4) the conveying of the cuttings, (5) the charging of the cuttings, (6) the mixing of the rubber material, (7) sheeting and cooling, (8) the stacking and storing of rubber sheets, (9) the granulating of the rubber sheets, (10) the mixing of rubber particles, (11) the weighing of the rubber particles, (12) the final mixing of rubber sheets, (13) sheeting and cooling, and (14) the stacking and storing of the rubber sheets. By the ripping of the rubber blocks, the granulating of the mother rubber sheets and two times of uniform mixings, the present invention realizes the uniform mixings of multiple batches of materials, so that the quality of the rubber material is more uniform and stable, and therefore the banburying effect is more ideal, and the following effects are achieved: The uniformity and stability of rubber mixing is improved, the efficiency of rubber mixing is increased, the impact damage of equipement is abated, and the automatization degree of material flowing is increased.
