Composition of auxiliary equipment for plastic granulation unit:

Wire laying device, straightening device, preheating device, cooling device, traction device, meter counter, spark testing machine, wire winding device.

The purpose of the extrusion unit is different, and the auxiliary equipment selected for it is also different. If there are also cutters, dryers, printing devices, etc.

Straightening device: The most common type of plastic extrusion waste is eccentricity, and various types of bending of wire cores are one of the important reasons for insulation eccentricity. In the extrusion of the sheath, scratches on the surface of the sheath are often caused by the bending of the cable core.

Therefore, straightening devices are essential in various extrusion units. The main types of straightening devices are: drum type (divided into horizontal and vertical types); Pulley type (divided into single pulley and pulley group); Twisted wheel, serving multiple functions such as dragging, straightening, and stabilizing tension; Roller type (divided into horizontal and vertical types), etc.
