A rubber mixing device

Abstract

The invention belongs to the technical field of rubber mixing, and specifically relates to a rubber mixing device, which includes a mixing box, a pressure plate, a hydraulic rod and a mounting frame; the mixing box is a rectangular tank-shaped structure with an open top; The banburying box is fixedly installed on the upper surface of the workbench; inside the banburying box, there are two groups of banburying rotors that rotate relatively; The side wall and the rotating shaft at the front end of the banburying rotor all protrude from the front side wall of the banburying box and are fixedly connected with the center of the circular gear disc; The refined raw materials are put into the raw material room inside the feeding box respectively, and the sliding sealing plate is pushed to move when the pressure plate is moved to realize the automatic addition of raw materials in order, without the need for staff to guard the side of the mixing device to feed, and will not Cause burns during feeding.

Description

technical field [0001] The invention belongs to the technical field of rubber internal mixing, in particular to a rubber internal mixing device. 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. [0003] When mixing rubber, it is necessary to add raw materials in strict order to ensure the quality of rubber. For example, in some processes, first add raw rubber for mixing for 1 minute, then add small materials and mix for 1.5 minutes, and then add carbon black...

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, to solve the problem of feeding in the prior art, the staff needs to be guarded by the side, and because the feeding is manual, and there is a certain temperature inside the banburying device, on the one hand, the personnel may burn their hands when feeding, and When the internal mixing device is opened, the volatile and harmful substances in the rubber will escape and cause harm to the body of the staff. A rubber internal mixing device proposed by the present invention
