Plastic granulator auxiliary equipment The auxiliary machine of the plastic granulating unit mainly includes a pay-off device, a straightening device, a preheating device, a cooling device, a traction device, a metering device, a spark testing machine, and a wire take-up device. The use of the extrusion unit is different for its optional auxiliary equipment. For example, there are also cutters, blowers, printing devices, and the like.
Straightening device: The most common type of plastic extrusion waste type is eccentricity, and the bending of various types of wire core is one of the important reasons for the insulation eccentricity. In sheath extrusion, the scratch on the surface of the jacket is also often caused by the bending of the core. Therefore, alignment devices in various extrusion units are essential. The main types of straightening devices are: drum type (divided into horizontal and vertical); pulley type (divided into single pulley and pulley group); winch type, which combines dragging, straightening, and stable tension; Pressure roller type (divided into horizontal and vertical).
