Plastic extrusion auxiliary unit includes pay-away device, alignment equipment, preheating equipment, cooling devices, traction devices, including rice, Spark Tester, Take-up device. Extruder by using different auxiliary tools for the matching are not the same, and cutting devices, drying devices, printing devices.
Straightening device
Types of plastic waste products out of the most typical one is eccentric, and different types of bending wire core is an important reason for generation of insulating eccentric. From the sheath, the sheath is normally often scratched the surface of the cable main by bending caused. Therefore, a number of extrusion unit in the alignment equipment is essential. The primary types of alignment devices are: drum (split into horizontal and vertical); Pulley (split into single pulley and pulley blocks); cutter steering wheel, and from the drag, alignment, stability, other results and tension; pressure wheel (split into horizontal and vertical) and so on.
Preheater
Cable core extrusion and nice jacket for the insulation extrusion are necessary. For the insulating level, especially in thin-layer insulation, can not permit the presence of pores, the brand primary in the extruded by temperature preheated before you can completely remove the surface of the water, oil. Speaking out for the coat, its main role is to dry the wire core and stop the moisture (or wrapped cushion of wetness) the purpose of the sheath pores may occur. Preheat could also prevent the extrusion of plastic due to quenching effect of residual pressure. In the plastic material extrusion method, the preheating heat to get rid of the cold series to enter the nasal area, mouth and plastic material in the mold created by the poor thermal contact and steer clear of temperature fluctuations caused by the plastic material extrusion pressure fluctuations, and therefore the quantity of stable extrusion to make sure that extrusion quality. Extrusion units are found in the hot main electrically preheating device requires sufficient capacity also to ensure rapid heating, the cable core wire core warm and high and dry efficiency. Preheating heat range by the release quickness of the constraints, like the nose temperature generally.
Cooling device
Layer of extruded plastic molding head double screw extruder left soon after the cooling setting, or found in the gravity deformation of Health and wellness issued the extruder. Cooled using water cooling typically, and according to distinct water temperature, divided into mild cold chill. Is the direct cooling drinking water quench, quench level of plastic extruded condition favorable, but the crystalline polymers, the primary heat due to cooling, easy to layer in the extruded internal residual stress, leading to cracking during use, generally PVC plastic coating is quenched. Slow cooling products is to reduce the internal anxiety in the sub-tank placed in the cooling water heat range, so that gradual cooling items, stereotypes, on the PE, PP extrusion on the usage of slow cooling, through the hot water namely, warm water, cool water three sections of cooling.
