Rubber mixing chamber facilitating burdening

The invention discloses a rubber mixing chamber facilitating burdening, and belongs to the technical field of rubber mixing devices. The rubber mixing chamber facilitating burdening comprises a mixingshell, two mixing rollers, a rubber cutting part and a burdening part, wherein an opening is formed in the upper part of the mixing shell; the two mixing rollers are arranged in the mixing shell sideby side in parallel; the rubber cutting part is arranged at the bottom of the mixing shell and is provided with a protruded cutting surface; the cutting surface is positioned between the two mixing rollers; the burdening part comprises a pressure supply device and a plurality of burdening cavities which are connected to the rear of the pressure supply device; a solenoid valve is arranged at an outlet of each burdening cavity; and the outlets of the burdening cavities are finally gathered at a pipeline and then communicate with the mixing shell. The rubber mixing chamber is used for mixing ofrubber on a mixer, the adding time and the adding amount of rubber ingredients are controllable, the ingredients can be added according to an actual process, mixing operation of rubber is precise, theingredients are easily dispersed uniformly, and the mixing time is shortened.
