Problems solved by technology

[0002] At present, the characteristics of the batching device sold on the market are: it can stir the materials and is easy to use; its disadvantage is: the temperature of the materials in the container changes with the change of the ambient temperature; the temperature of the materials in winter is relatively low, which will cause The kinematic viscosity of the adhesive increases, which will make it difficult to apply the adhesive or waste a large amount of dilution solvent; in summer, the temperature of the material is high, which will easily cause the material to react in advance, and will also cause a large amount of solvent volatilization, which not only causes the material waste and pollute the environment, and it will also lead to an increase in the solid percentage of raw materials, making the viscosity of the next product unstable, and it is easier to cause gelation of the adhesive and lead to unnecessary waste

Abstract

The invention discloses a phase change constant-temperature batching device. The phase change constant-temperature batching device comprises a batching barrel body, a driving motor, a speed reducer, a stirring shaft, a stirring paddle, a main material feeding inlet, an auxiliary material feeding inlet, a discharge port, support legs, brake universal wheels, a phase change constant-temperature assembly, a shoulder part temperature preservation layer, a temperature preservation layer, a grounding wire and a phase change constant-temperature assembly. The phase change constant-temperature batching device is characterized in that the phase change constant-temperature assembly surrounds the outer ring of a batching barrel and is folded by a convex-concave embedded mortise and tenon joint. According to the invention, the usage of excessive diluting solvents caused by sticky materials can be prevented in winter; the reaction of materials in advance because of too high temperature can be prevented in summer; the pollution to the operation field caused by volatile organic solvents because of too high temperature is reduced; scrappage caused by gel of adhesives because of solvent evaporation also can be prevented; conditions are created for production quality and performance stability.
