Heating device for plastic particles

Abstract

The utility model discloses a heating device for plastic particles, which relates to the field of plastic particle heating devices and comprises an extruder main body and ceramic heaters detachably mounted on the extruder main body, and the ceramic heaters are symmetrically mounted on the extruder main body in an annular structure. Mounting terminals are fixed to the two ends of the ceramic heater, a mounting groove is formed in the ceramic heater, through holes are formed in the inner wall of the mounting groove, a connecting rod is mounted between every two adjacent through holes, and an anti-falling part is fixed to one end of each connecting rod; and clamping blocks in damping connection with the inner walls of the mounting grooves are elastically arranged at the other ends of the connecting rods. According to the plastic particle extruder, heat loss caused by airflow is avoided, the heating effect on the plastic particle extruder is improved, the connecting rods are pulled out of the through holes after the extrusion clamping blocks are contracted into the telescopic grooves, and the convenience of mounting and dismounting of the ceramic heater is improved.
