Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic product production, in particular to an efficient internal mixer for rubber and plastic product production. Background Art

[0002] At present, for the rubber mixing of raw materials of rubber and plastic products, the internal mixer is highly efficient for rubber mixing. However, for traditional internal mixers, different kinds of auxiliary materials need to be manually added at different time periods for mixing. For example, an internal mixer for rubber processing disclosed in the patent with the publication number CN221456402U pre-crushes through a crushing box and then sends it into the internal mixing box for internal mixing, and realizes the function of dust collection through a dust collector. During internal mixing, it is necessary to heat up for internal mixing and manually add different auxiliary materials at different rubber mixing time periods. Manual addition is rather troublesome and cannot accurately control the quantity, nor can it ensure uniform spreading on the rubber material, which will cause the auxiliary materials to be concentrated and embedded, resulting in uneven mixing. At the same time, during internal mixing, the rubber is heated up for mixing, but after discharging, it is mostly left to cool naturally, which will cause waste of thermal energy and slow cooling speed. Therefore, the utility model proposes an efficient internal mixer for rubber and plastic product production to solve the problems existing in the prior art. Content of the Utility Model

Multiple groups of distributed material spreading ports can evenly spread the auxiliary materials on the rubber material, improving the internal mixing efficiency. Through the cooling and discharging mechanism, the internally mixed rubber material can be quickly cooled and output, and at the same time, the thermal energy can be recycled, avoiding energy waste and greatly improving the practicability.
