Wherein, 1, a hot melting barrel 2, an inlet 3, an outlet 4, a stirring shaft 5, a stirring blade 6, a heating pipe 71, a preheating section 72, a high temperature section 73, a uniform temperature section 8 and a necking part.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in figure 1, a plastic melting device comprises a hot melting barrel 1, wherein the hot melting barrel is provided with a left inlet 2 and a right outlet 3, a stirring shaft 4 is arranged in the hot melting barrel, a plurality of stirring blades 5 are further arranged on the stirring shaft, a plurality of heating pipes 6 are further arranged around the hot melting barrel, and the heating pipes can heat raw materials; the method is characterized in that: the section of the hot melting barrel close to the outlet is a temperature equalizing section 73, and heating pipes are not arranged around the temperature equalizing section.
The utility model is arranged in such a way that the raw materials are not heated in the temperature equalizing section, and the raw materials only have the effect of uniform mixing in the temperature equalizing section, so that the raw materials coming out of the outlet are at one temperature, and the aim of the utility model can be realized.
The heat absorbed by the feedstock prior to entering the soaking stage is sufficient to reach the post-mixing temperature. In order to achieve the purpose, a heating pipe can be additionally arranged on the hot melting barrel in front of the temperature equalizing section. For example, a heating pipe laid on the hot-melt tank near the outlet in the prior art is moved to the front thereof.
Further, the front of the temperature equalizing section is provided with a preheating section 71 and a high temperature section 72 from the inlet to the back, and a necking part which contracts towards the inner cavity of the hot melting barrel is arranged between the high temperature section and the temperature equalizing section.
The utility model is more beneficial to the uniformity of the temperature of the raw materials at each position of the temperature equalizing section, and achieves the purpose and better effect.
Further, the cross section of the necking portion is formed by an arc, as shown in the lower necking portion in fig. 1, and the upper necking portion in fig. 1 is another embodiment.
The utility model has the advantage that the resistance to the flow of raw materials can be reduced.
Further, the length of the temperature equalizing section occupies 1/3 to 2/5 of the internal length of the hot melting barrel.
The utility model has the advantage of more reasonable design.
Further, there are no stirring vanes around the stirring shaft below the inlet.
The utility model has the advantage of reducing plastic particles entering the hot melting barrel from flying out.
The present utility model is not limited to the preferred embodiments, and any person skilled in the art can make some changes or modifications to the equivalent embodiments without departing from the scope of the present utility model, but any simple modification, equivalent changes and modifications to the above embodiments according to the technical principles of the present utility model are still within the scope of the present utility model.
