Description
Technical field
The invention belongs to extruding machine technical field, particularly relate to a kind of heating system and extruding machine thereof of extruding machine.
Background technology
Extruding machine is the screw rod utilizing given shape, rotate in the machine barrel of heating, machine barrel and heating means touch tightr, heating effect is better, but current heating means general resistance wire or pipeline heating mode, after the extrusion molding raw material in machine barrel is heated, production required product is carried out again by extruded mould, in heating process, there is heating uneven, heating process is comparatively slow, the shortcomings such as energy resource consumption is large.
Summary of the invention
The problem to be solved in the present invention is that extrusion process can not realize homogeneous heating, avoid due to heating tube heat radiation and barrel zone temperature change steady, the heat loss caused or heat fluctuated, affects output and the effect of extrusion molding.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of heating system of extruding machine, comprise the heater be wrapped on extruder barrel outer wall, and be wrapped in thermal insulation layer and the heat-insulation layer of heater outside successively, the outer wall of extruder barrel is provided with at least one temperature sensor, the outer setting of heating system has air-supply passage, and the air inlet of air-supply passage is connected with blower fan; This heating system also comprises control device, and the input of control device is connected with the output of temperature sensor, and the output of control device is connected with the input of blower fan, heater.
Further, air-supply passage is provided with at least one air outlet towards extruder barrel direction.
Further, heater is electromagnetic heater.
Further, heat-insulation layer material is rock wool heat-preservation material.
Further, insulating layer material is metal-foil composite.
This invention also provides a kind of extruding machine, and this extruding machine comprises any one heater above-mentioned.
The advantage that the present invention has and good effect are: the present invention is evenly arranged on the outside of machine barrel and the Real-Time Monitoring of temperature sensor by heater, ensure that the homogeneous heating of heater and the controllability of temperature, overall performance is good, easy to use, and can heat be kept for a long time not distribute, energy saving.
