Cold-feed rubber extruder is widely used in the rubber industry. In radial tire production, tread grooves, compound tread extrusions, horn rubbers, and various types of rubbers have three-dimensional spiral grooves corresponding to the spiral grooves. The nail is directly inserted into the circular grooves of the pin, and the rubber material performs lateral movement, flow movement, and partial rotation movement under the action of the pins. Due to the combined effect of these three types of movement, the core formed during the extrusion of the rubber can be effectively destroyed. Whenever the core passes through the pin, it will be cut once. After each rotation of the spiral, the rubber will be divided and cut by a bunch of pins, which strengthens the kneading and accelerates the rubber in the screw groove of the screw. Medium flow, so you can get high-quality mixed, kneaded and plasticized compounds.
