Description

Technical Field

[0001] The utility model relates to the technical field of insulating material production, in particular to an insulating material mixing device for photovoltaic cables. Background Art

[0002] Compounding is the process of mixing raw rubber or plasticized raw rubber with compounding agents into compound rubber using a rubber mixer. It is the most important production process in rubber processing. In essence, it is the process of uniformly dispersing the compounding agent in the raw rubber. The granular compounding agent is in the dispersed phase and the raw rubber is in the continuous phase. The compounding process includes four stages: mixing, dispersing, mixing and plasticizing. The raw rubber or plastic rubber is subjected to shear and stretching in the rubber mixer to produce rheology, fracture and crushing, so as to fully contact with the compounding agent and mix it in.

[0003] The existing device drives the stirring components such as the stirring rod to rotate through a motor, so as to disperse the compounding agent in the raw rubber. When the compounding agent enters the mixing device from the feed inlet and falls into the raw rubber, it is relatively concentrated, which will prolong the time for evenly dispersing the compounding agent in the raw rubber, affecting the mixing efficiency. At the same time, the compounding agent gathers together, which is easy to cause uneven dispersion, thereby affecting the uniformity of mixing and causing the quality of the finished product after mixing to decrease. Summary of the invention

[0007] More preferably, the material conveying channel includes a main channel connected to the feed port and several branch channels connected to the main channel; the several branch channels are evenly distributed on the outside of the main channel and the ends are against the side wall of the barrel body; the several spreading ports are evenly distributed at the bottom of the branch channels.

[0008] Preferably, the mixing assembly includes a motor fixed to the bottom of the barrel with a driving end penetrating the bottom wall of the barrel, a rotating roller fixedly connected to the driving end of the motor, and a plurality of stirring rollers fixed outside the rotating roller; the driving gear is fixed to the top of the rotating roller.

[0009] More preferably, the stirring roller includes a fixed rod fixed to the rotating shaft, a sleeve sleeved outside the fixed rod and rotatably connected to the fixed rod, and a plurality of spiral blades evenly distributed outside the sleeve.

[0010] More preferably, a push plate is fixedly connected to one side of the bottom end of the rotating roller, and the bottom of the push plate is in contact with the bottom wall of the barrel body and the side away from the rotating roller is in contact with the side wall of the barrel body.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model cooperates with the feed port, the feed channel and the spreading port. After the compounding agent is poured into the feed port, the compounding agent will fall from several spreading ports through the feed channel, so as to achieve uniform dispersion of the compounding agent on the top of the raw rubber, thereby improving the mixing efficiency and the mixing degree, thereby improving the quality of the finished product;
