The auxiliary equipment of the extruder（1）

The auxiliary equipment of the plastic extrusion unit(extruder) mainly includes setting out device, straightening device, preheating device, cooling device, traction device, meter counter, spark tester and take-up device. The purpose of the extrusion unit is different, and the auxiliary equipment selected is also different, such as cutter, dryer, printing device, etc.

Straightening device of the extruder
The most common type of plastic extrusion waste（extruder) is eccentricity, and various types of bending of wire core is one of the important reasons for insulation eccentricity. During sheath extrusion, the scratch on the sheath surface is often caused by the bending of the cable core. Therefore, the straightening device in various extrusion units is essential. The main types of straightening devices are: roller type (divided into horizontal type and vertical type); pulley type (divided into single pulley and pulley block); winch type, which plays a variety of roles such as driving, straightening and stabilizing tension; roller type (divided into horizontal type and vertical type), etc.
