Rubber internal mixer with graded mixing function

Abstract

The invention discloses a rubber internal mixer with a graded mixing function, which comprises an internal mixer body, and the internal mixer body internally comprises a primary mixing box, a mixing box and a storage part from top to bottom in sequence; the storage part further comprises a discharging port in the bottom; the mixing box is obliquely installed in the middle of the internal mixer body; the mixing box comprises a first rotating shaft and a first spiral blade which are matched with each other; a connecting shaft matched with the first rotating shaft is arranged outside the mixing box; a motor box connected with the connecting shaft is arranged outside the internal mixer body; the mixing box further comprises a material blocking plate and a buffering bottom plate which are located on the top of the inner side of the mixing box; a buffering discharging groove is arranged at the connecting position of the first rotating shaft and the material blocking plate; limiting blocks are evenly arranged at the positions, located on the periphery of the first rotating shaft, in the mixing box; a homogenizing assembly is arranged in the storage part; and a filtering assembly is arranged in the primary mixing box. When the rubber internal mixer with the graded mixing function provided by the invention is used, molten and mixed materials can stay in the mixing box for a longer time, so that the effect of enhancing the mixing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of internal mixers, in particular to a rubber internal mixer with the function of graded mixing. Background technique [0002] The closed type rubber mixer is referred to as internal mixer, also known as kneader, which is mainly used for plasticizing and mixing of rubber. Internal mixer is a kind of machine with a pair of rotors with specific shape and relative rotation, which intermittently plasticizes and kneads polymer materials in a closed state with adjustable temperature and pressure. It is mainly composed of a mixing chamber, a rotor , Rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base and other parts. Banbury mixing is an important link in the production process of functional rubber. Factors such as the order of feeding in the banbury process determine the performance of the product to a large extent, and the process of adding corresponding mate...

Problems solved by technology

[0003] Because the mixing process of rubber products needs to add different materials at different times, and the process needs to be fully stirred evenly, so in the process of mixing materials, stable stirring is extra important. The existing integrated internal mixer In the process of graded mixing, the mixing effect is not ideal, and the mixing of graded and divided bins is not only troublesome in operation, but also affects production. Therefore, an integrated graded mixing rubber banbury that can fully mix materials is proposed. machine
