Extruder cooling system

Abstract

The invention discloses an extruder cooling system. The extruder cooling system comprises an air supply device, a stator extending leftwards and rightwards, and a rotor rotatably mounted in the statorand extending leftwards and rightwards. A plurality of cooling mechanisms are arranged outside the stator in a sleeving mode and are distributed in a spaced mode in the left-right direction. Each cooling mechanism comprises a fan cover body matched with the stator in size and shape. The fan cover bodies are arranged on the periphery of the stator in a sleeving mode, and a cooling cavity is formedby the fan cover bodies and the outer side face of the stator. Air inlets and air outlets which communicate with the cooling cavity are formed in the walls of the fan cover bodies. The air inlets areconnected with air amplifiers. The air supply device is connected with the air amplifiers. The pressure of cooling air from the air supply device is amplified through the air amplifiers, then the cooling air enters the cooling cavity to cool the stator, and finally, the cooling air is exhausted via the air outlets; and different extrusion sections of the stator are cooled through the multiple cooling mechanisms, so that the cooling effect is flexibly adjusted. The extruder cooling system is used for regulating and controlling the temperatures of the extrusion sections of an extruder.

Existing systems use multiple sets of cooling devices to cool the extruder to achieve temperature control for each extrusion section. However, the existing extrusion The cooling system of the machine also has the problem of poor adjustment performance. There is a certain delay in temperature control, and it cannot be adjusted to a certain temperature quickly.
