The equipment has the characteristics of high production capacity, low temperature of rubber material, less energy consumption, good mixing quality, uniform plasticization, etc., with a bolt can uniformly and stably extrude a variety of mouth type rubber material, so it can be widely used in rubber hose, inner tube, tape, lining, sealing strip, wire and cable, sheath, side table, submouth rubber and other extrusion molding. Products are XJ-65, XJ-90, XJ-120, XJ-150, XJ-200 and other models to meet different customer needs.
Cold feed rubber extruder is a kind of rubber industry equipment. Cold-fed rubber extruders are widely used in China's rubber industry. In the production of radial tires, annular grooves are opened in the spiral parts corresponding to the three phases of tread extrusion, compound tread extrusion, Angle glue and various types of rubber. The nail is directly inserted into the ring groove of the pin, and the rubber material moves laterally, fluidly and rotatally under the action of these pins. Due to the combined action of these three forms of movement, the core formed during the extrusion of rubber material can be effectively destroyed. Each time the core passes through the pin, it is cut once, and each rotation of the screw, the glue is divided and cut by a handful of pins, strengthening the kneading and accelerating the flow of the glue in the screw thread groove, so that high-quality mixing, kneading and plasticizing glue can be obtained.
Due to the insertion of the pin, the ability to mix, knead and plasticize is strengthened, under the same extrusion conditions, the working length of the screw can be shortened 2D-4 compared with the ordinary cold feed extruder, and the time of the material staying in the barrel is shortened due to the reduction of the length-diameter ratio. Almost all of the extruders that produce rubber are pin-type cold feed rubber extruders. In the bias viviparous birth, in recent years, the replacement of hot feed extruder with pin type cold feed rubber extruder has been the trend, the rapid development, such as tread compound extrusion, various triangle glue, various types of rubber extrusion, many production plants have used pin type cold feed rubber extruder. In the production of rubber hose, the inner rubber extrusion and outer rubber extrusion also use the cold-fed pin rubber extruder.
