Description

Technical Field

[0001] The utility model relates to rubber or plastic raw material processing equipment, in particular to an all-in-one mixing and extruding machine. Background Art

[0002] Internal mixer and extruder are commonly used equipment for producing high-viscosity rubber products. The internal mixer mainly includes an internal mixing chamber, a mixing feed port is arranged on the top of the internal mixing chamber, and two rotors are arranged in the internal mixing chamber to mix the rubber raw materials. The extruder mainly includes a barrel, a feeding screw driven by a motor is arranged in the barrel, a feed barrel is connected to the top wall of one end of the barrel, and an extrusion die is connected to the other end of the barrel. During production, first load the rubber raw materials into the mixing chamber from the mixing feed port, and complete the mixing of the rubber through the relative rotation of the two rotors in the mixing chamber. After the mixing is completed, the mixing chamber is turned over to discharge the mixed rubber from the mixing feed port into the collecting barrel, and then the collecting barrel is transported to the extruder, and the rubber in the collecting barrel is poured into the feed barrel from the feed port of the feed barrel. The rubber will fall into the barrel from the discharge port of the feed barrel, and the rotating feed screw in the barrel further extrude and shear the rubber. The rubber is further extruded and sheared by the feed screw and is transported to the extrusion mold. The rubber is extruded and molded in the extrusion mold while being cooled, thereby forming the desired product. The above-mentioned internal mixer and extruder are separate, and the two need to be transported through the barrel, resulting in relatively low processing efficiency.

[0003] There is a feeding device for conveying rubber in a banburying extruder, which is a Chinese invention patent with the patent number of ZL2017110616564. The feeding device mainly uses a conveying screw to convey the banburying rubber to the feed port of the extruder. Since the length of the conveying screw is related to the distance between the banburying outlet and the feed port of the extruder, when the distance between the banburying outlet and the feed port of the extruder is large, the length of the conveying screw required will be very long, and the equipment used to install the conveying device will increase the installation length of the equipment, resulting in a larger overall size of the equipment, which is not conducive to transportation, handling and utilization of the equipment site, and the setting of the conveying device directly increases the cost of the equipment. Summary of the invention
