Abstract

The utility model discloses a plastic heating device which comprises a body and a binding post fixedly arranged on the body. The body is a hollow post body made of electric heat material. By adopting the structure, the plastic heating device is arranged inside a charging barrel and the body is a hollow circle cylinder, plastics arranged inside and outside the body can be heated at the same time, and therefore the plastics inside the charging barrel can be heated evenly. In addition, by means of the plastic heating device, use ratio of electric energy is improved, and emitted heat is almost all absorbed by surrounding plastics.

Description

The plastics heater

Technical field

The utility model relates to a kind of heater, especially a kind of plastics heater.

Background technology

At present, the most heating cabinets of being made up of casting aluminium heating collar, ceramic electrical heating collar that adopt of the mode of heating of plastic extruder heat outside barrel, exist drawbacks such as energy consumption height, non-uniform temperature, equipment investment are big.

Summary of the invention

The technical problem that the utility model will solve provide a kind of simple in structure, energy consumption is low, homogeneous heating, plastics heater that cost is low.

In order to solve the problems of the technologies described above, the utility model comprises main body, is fixedly installed on binding post and lead-in wire on the main body; Said main body is the cylinder of the hollow processed by thermo electric material.

Adopt such structure; Because this plastics heater is arranged at barrel inside and main body is the cylinder of hollow; Being positioned at the inside and outside plastics of main body can be heated simultaneously; Plastics in the barrel are heated more evenly like this, adopt this heater also to improve the utilization rate of electric energy, its heat that distributes almost entirely by around plastics absorb.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:

Fig. 1 looks sketch map for the master of the utility model plastics heater;

Fig. 2 is the schematic top plan view of the utility model plastics heater.

The specific embodiment

Referring to Fig. 1 and Fig. 2, the plastics heater of the utility model comprises main body 1 and is fixedly installed on the binding post 2 on the main body 1 and goes between 3; Said main body 1 is the cylinder of the hollow processed by thermo electric material.

This plastics heater is arranged at barrel inside; Electric current arrives main body 1 through lead-in wire 3 and binding post 2; The main body 1 that thermo electric material is processed begins heating, to plastics heating on every side, because main body 1 is the cylinder of hollow; Being positioned at main body 1 inside and outside plastics can be heated simultaneously, and the plastics in the barrel are heated more even like this.The heat that this device distributes is almost absorbed by plastics on every side entirely, thereby has improved the utilization rate of electric energy.

In sum, the content of the utility model is not confined in the above embodiments, and those skilled in the art can propose other embodiment within technological guidance's thought of the utility model, but these embodiment are included within the scope of the utility model.

Claims (1)

1. plastics heater, this heater is positioned over barrel inside, it is characterized in that: said plastics heater comprises main body (1), is fixedly installed on binding post (2) and lead-in wire (3) on the main body (1); Said main body (1) is the cylinder of the hollow processed by thermo electric material.
