Open mill for mixing rubber

The invention relates to the field of rubber processing equipment, in particular to an open mill for rubber mixing, which comprises supporting legs, a shell, a feeding device, a mixing device, a liquid feeding device, a scraping device and a discharging device, and solves the problem that the existing open mill is inconvenient to use due to the fact that mixed rubber materials are extruded by two relatively rotating rollers in the actual use process. The technical problems of long time consumption and low mixing efficiency due to the fact that the aim of fully and uniformly mixing cannot be achieved through single-time extrusion and the sizing material can reach the specified uniformity only through repeated extrusion for multiple times in the prior art are solved. 本发明涉及橡胶加工设备领域，具体说是一种混炼橡胶用开炼机，包括支腿、壳体、进料装置、混炼装置、送液装置、刮料装置和出料装置，本发明解决了现有的开炼机在实际使用过程中由两个相对回转的辊筒将混合后的胶料进行挤压，由于单次挤压无法达到充分混合均匀的目的，所以需要进行多次反复挤压才能使胶料达到符合规定的均匀度，导致花费时间较长，混炼效率较低的技术问题。
