Novel heat concentrating and energy saving device of plastic extruding machine

Abstract

The invention provides a novel heat concentrating and energy saving device of a plastic extruding machine. In the device, a screw rod of the plastic extruding machine is engraved to form a hollow shaft in a material barrel, and a heat insulating barrel is arranged in the hollow shaft and is connected with the hollow shaft structure. The center of the heat insulating barrel is engraved, and the distance for radiating heat to the center of a screw shaft is reduced, so that the heat is concentrated between the material barrel and the screw rod, and the novel heat concentrating and energy saving device has the advantages of heat concentration, energy saving, increased heat efficiency, increased torsion of the screw rod, quickness in the maintenance of the material barrel and the heat radiation of the screw rod and simple structure.

Description

Technical field: [0001] Involves injection molding machines and rubber extruders. Background technique: [0002] At present, the fillers of injection molding machines and rubber extruders are heated and melted, and the thermal efficiency is uneven. Too high heating temperature of the screw leads to reduced torque, weakened strength, and slow heat dissipation of the mechanical maintenance screw, which has a great impact on the working efficiency of the extruder. Invention content: [0003] In order to overcome the above deficiencies, the present invention provides a novel heat-gathering and energy-saving device for plastic extruders. The technical scheme that the present invention solves its technical problem to take is: [0004] Inside the barrel, the screw of the plastic extruder is hollowed out into a hollow shaft. [0005] A heat insulating cylinder is installed in the hollow shaft to connect with the hollow shaft structure, which prevents the heat transfer of the scr...

AI Technical Summary

Problems solved by technology

[0002] At present, the fillers of injection molding machines and rubber extruders are heated and melted, and there are uneven thermal efficiencies. Excessively high heating temperature of the screw leads to reduced torque, weakened strength, slow heat dissipation of the mechanical maintenance screw, etc., which have a great impact on the working efficiency of the extruder.
