Description

A kind of extruder barrel heater

Technical field

This utility model is related to extruder barrel heater technical field, more particularly, to a kind of extruder barrel heater.

Background technology

Range with extruder becomes wide, and extruder heater is one important ingredient of extruder, people It is to mould at present to compile the critically important research topic of industry energy-saving aspect to extruder reconstruction of heater, original extruder barrel heating The rosette of device is designed as copper foundry goods, and space is restricted, and close from heater body, leads in rosette temperature relatively Height, there is a possibility that high temperature cable lost efficacy, and existing extruder barrel heater practicality is not strong, security performance is not Height is it is impossible to meet the use demand of people well.

Utility model content

The purpose of this utility model is to solve shortcoming present in prior art, and a kind of extruder barrel proposing Heater.

To achieve these goals, this utility model employs following technical scheme：

A kind of extruder barrel heater, including thermal insulation protection shell, heater binding post, ventilation duct and heater body, Inside described heater body, resistive heater is installed, described heater body inner surface is provided with thermal source, described heater Above body, ventilation duct is installed, and having heaters binding post is installed inside ventilation duct, described heater binding post passes through electric wire It is connected with rosette binding post, above described ventilation duct, heater connection box is installed, be provided with the left of described heater body Thermal insulation protection shell is installed on the left of machine barrel heat-insulation layer, and machine barrel heat-insulation layer, inside described thermal insulation protection shell, barrel is installed, and spiral shell Cylinder is internal to be provided with bolt, is provided with handle above described thermal insulation protection shell.

Preferably, described bolt cuts with spiral fluted column structure for outer surface.

Preferably, described heater connection box is provided with two altogether, and two heater connection boxes are symmetrically mounted on heating Device body both sides.

Preferably, described handle is provided with two altogether, and two symmetric handles are arranged on thermal insulation protection shell both sides.

Preferably, described barrel cuts with the hollow cylindrical structure of thread groove for the inner surface that metal material is made.

In this utility model, by being provided with barrel and bolt, on the one hand improve stablizing of extruder barrel heater Property, on the other hand facilitate operator that heat-barrier coating is dismantled, thus the portion to this extruder barrel heater body Part is changed and is overhauled, and by being provided with thermal source, and machine barrel is completely surrounded by thermal source, so that machine barrel is heated all Even, so that the material of inside machine barrel is heated more preferably uniformly, improve the production qualification rate of material in machine barrel, by heating Device rosette is changed to aluminum stamping parts from copper foundry goods, rosette and heater body is adopted ventilation duct, makes between them Distance is not less than 60 millimeters, and increases the thick heat-insulation layer of at least 15mm between them, thus increasing the sky of junction box Between, reduce manufacturing cost, reduce the internal temperature of this heater connection box, through actual measurement, heater body temperature is 300 DEG C, junction box temperature is 100 DEG C, so the high temperature cable of heater can reduce a class, is also reduction of manufacture Cost.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.

With reference to Fig. 1-2, a kind of extruder barrel heater, including thermal insulation protection shell 2, heater binding post 6, ventilation duct 10 With heater body 11, resistive heater 13 is installed inside heater body 11, heater body 11 inner surface is provided with heat Source 12, is provided with ventilation duct 10 above heater body 11, and the internal installation having heaters binding post 6 of ventilation duct 10, heater Binding post 6 is connected with rosette binding post 9 by electric wire 7, is provided with heater connection box 8 above ventilation duct 10, and heater is originally Machine barrel heat-insulation layer 5 is installed on the left of body 11, and thermal insulation protection shell 2 is installed, inside thermal insulation protection shell 2 on the left of machine barrel heat-insulation layer 5 Barrel 4 is installed, and bolt 3 is installed inside barrel 4, handle 1 is installed above thermal insulation protection shell 2, bolt 3 is cut for outer surface There is spiral fluted column structure, heater connection box 8 is provided with two altogether, and two heater connection boxes 8 are symmetrically mounted on and add Hot device body 11 both sides, handle 1 is provided with two altogether, and two handles 1 are symmetrically mounted on thermal insulation protection shell 2 both sides, and barrel 4 is The inner surface that metal material is made cuts with the hollow cylindrical structure of thread groove.

Operation principle：When using extruder barrel heater, extruder barrel is inserted in this extruder barrel heater Thermal source 12 inner surface, the rosette binding post 9 in heater binding post 6 and heater connection box 8 is linked together, so Resistive heater 13 within heater body 11 starts to generate heat, and thermal source 12 absorbs the heat of heater body 11 radiating, and will Heat is conducted to extruder barrel, and this heater connection box 8 is arranged on thermal insulation protection shell 2 periphery, with heater body 11 distance Become big, and between heater connection box 8 and heater body 11, increased ventilation duct 10, heater wiring can be effectively reduced Box 8 and the own temperature of heater body 11, machine barrel heat-insulation layer 5 can effectively completely cut off heater connection box 8 and heater body Heat transfer between 11, can avoid heater connection box 8 internal temperature higher, there is a possibility that high temperature cable lost efficacy.

The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not Be confined to this, any those familiar with the art in the technical scope that this utility model discloses, according to this practicality New technical scheme and its utility model design in addition equivalent or change, all should cover in protection model of the present utility model Within enclosing.
