Problems solved by technology

[0005] Although the above two patents can effectively foam, they cannot dry the foamed beads without a power-off protection device. If a power-off occurs during the foaming process, the particles in the foaming barrel will inevitably stick together, affecting Processing, and the feeding process is too troublesome, the degree of automation is not high, and the mixing effect is not very good

Abstract

The invention discloses a full-automatic intermittent type pre-foaming machine. A steam conveying pipeline is communicated with the bottom end of a pre-foaming machine barrel. A negative-pressure feeding device is connected with a metering weighing device and provided with a vacuum generator used for sucking in raw materials in the metering weighing device. The negative-pressure feeding device is arranged above the pre-foaming machine barrel and communicated with the pre-foaming machine barrel. A stirring device is arranged above the pre-foaming machine barrel. The stirring device is provided with a cross-shaped stirring block used for stirring the raw materials in the pre-foaming machine barrel. A sensor used for detecting the foaming degree is arranged on the inner wall of the pre-foaming machine barrel. The pre-foaming machine barrel is connected with a vulcanization drying device. The steam conveying pipeline, the pre-foaming machine barrel and a control system are installed on a rack. The rack is further provided with a power-off protection device connected with the pre-foaming machine barrel to prevent the raw materials in the pre-foaming machine barrel from being bonded after powering off. The full-automatic intermittent type pre-foaming machine can carry out effective drying, foaming particles are not bonded after powering off, the automation degree is high, stirring is even, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of foam machinery, in particular to a fully automatic intermittent pre-expansion machine. Background technique [0002] Before EPS products are molded, they need to go through a pre-expansion stage so that the bulk density of the molded product can be better controlled in a lower range. During the pre-expansion process, the beads containing the foaming agent are slowly heated to above 90°C and begin to soften , The foaming agent in the beads is heated and vaporized to generate pressure to expand the beads, and the pre-expansion can reduce the density gradient during molding and uniform expansion molding. [0003] CN2668373Y discloses a kind of intermittent pre-blowing machine, comprising computer control box, feeding device, steam pipeline device, discharging device, it is characterized in that described feeding device is connected with electronic weighing device, and electronic weighing device is connected ...
