Description

Rubbing mill

Technical Field

The utility model relates to the technical field of mixing equipment, in particular to a rubbing mill.

Background

The mixer is a mechanical device for uniformly mixing two or more materials by using mechanical force and gravity. The traditional mixer is provided with a stirrer in the cylinder, and materials in the cylinder are mixed through rotation of the stirrer, so that the efficiency of the mixer is generally low and the energy consumption is high. With the progress of the times, mixers with agitators and barrel reversing have been invented which are efficient and less time consuming.

The Chinese patent with publication number CN202725127U discloses a fusion machine which mainly comprises an integral frame, a power transmission mechanism, a rotary cylinder body, a scraper group, an extrusion punch group and an intelligent control cabinet mainly composed of a PLC, wherein the rotary cylinder body is respectively provided with a feed inlet for inputting mixed materials and a discharge outlet for discharging powder after processing; the rotary cylinder body and a rotary shaft form a rotary body together and are connected with a motor controlled by the intelligent control cabinet through a coupler and a belt pulley device; the rotary cylinder body is internally provided with a scraper group and an extrusion punch group which are fixed on the rotary shaft, and the rotary cylinder body is externally provided with a layer of interlayer for cooling water to flow.

The applicant improves the above-mentioned mixer and obtains Chinese patent application authorization (publication No. CN 207413289U), wherein the mixer comprises a frame, a power transmission mechanism controlled by a PLC software program, a rotary cylinder, a rotary hammer head and a cooling mechanism, wherein the power transmission mechanism and the rotary cylinder are arranged on the frame, the power transmission mechanism can enable the rotary hammer head and the rotary cylinder which are arranged in the rotary cylinder to rotate reversely, powder materials arranged in the inner cavity of the rotary cylinder can be completely fused together under the action of external forces such as rubbing, rolling and kneading, and the cooling mechanism is arranged outside the rotary cylinder in a surrounding way, so that the rotary cylinder can be cooled down rapidly. The utility model can better inlay and compound two or more powder materials to achieve a complete fusion state, and greatly improves the performance of the powder materials.

However, the applicant found through practice that when external force is applied to the mixed material through the rotary hammer head, the mixed material is scattered to two sides of the hammer head after being stressed due to small working area of the rotary hammer head, so that incomplete material fusion is caused, the fusion effect is poor, and the performance of the material is affected.
