Abstract
The utility model discloses a screw rod heating system of a plastic extruding machine. The screw rod heating system comprises a plurality of heating units, and each heating unit is provided with an electromagnetic heating coil wrapping a screw rod, a heat insulation layer is arranged outside each electromagnetic heating coil in a sheathed manner, an anti-radiation layer is arranged outside each heat insulation layer, a housing is arranged outside each anti-radiation layer, an opening part, which is convenient for mounting, is formed in the housing, and a bolt is arranged above the opening part for controlling the size of the opening part. The screw rod heating system disclosed by the utility model has the advantages of simple structure, high heating efficiency, convenience in mounting, good heat preservation effect and low heat loss, and can alleviate electromagnetic pollution due to the anti-radiation layers.
Description
Technical field
The utility model relates to a kind of heater, relates in particular to a kind of screw rod heating system of extruding machine.
Background technology
In cable production process, the screw rod of extruding machine need to heat and plastic raw materials melted and make it to be coated on metal cable core outside, to play insulation and protective effect.Existing screw heating device mostly is Resistant heating, causes the efficiency of heating surface low, and power consumption is large, makes production cost high, therefore needs badly and changes existing heater.
Utility model content
In order to solve the problem relating in background technology, the utility model provides a kind of screw rod heating system of extruding machine.
The technical solution of the utility model is: a kind of screw rod heating system of extruding machine, comprise a plurality of heating units, described heating unit is provided with the electromagnetic system heat coil being wrapped in outside screw rod, described electromagnetic system heat coil is arranged with thermal insulation layer outward, described thermal insulation layer is provided with radiation protective layer outward, described radiation protective layer is provided with housing outward, and described housing is provided with peristome, and described housing is bolted with for controlling the bolt of the openings of sizes of peristome.
As of the present utility model a kind of preferred, on described housing, be also provided with inlet wire terminal plate and outlet terminal plate, on described inlet wire terminal plate and outlet terminal plate, be equipped with binding post, described binding post is used for being electrically connected to external power source and electromagnetic system heat coil.
As of the present utility model a kind of preferred, also comprise temperature sensor, the detection head of described temperature sensor contacts for detection of the temperature of described screw rod with described screw rod.
As of the present utility model a kind of preferred, the asbestos that described thermal insulation layer is 2-3mm by thickness are made.
As of the present utility model a kind of preferred, described radiation protective layer is made by stereotype.
In sum, the utlity model has following advantage:
The utility model is simple in structure, and the efficiency of heating surface is high, easy for installation, and high insulating effect, and thermal loss is little, has again radiation protection layer, has reduced electromagnetic pollution.
