Description

technical field [0001] The invention relates to a foaming machine and a process method thereof, in particular to a high-speed and high-precision energy-saving foaming machine and a process method thereof. Background technique [0002] The foaming equipment currently on the market includes a feeding device, a foaming tank and a drying bed. The feeding device is to weigh a certain amount of EPS hard particles, and then use compressed air to send it to the foaming tank; Steam with a certain temperature is introduced into the foaming tank, and after a certain period of time, the EPS hard particles will expand into light foam particles; when the foam particles reach the specified density, open the outlet of the foaming tank, and The foam particles are put into the drying bed and passed through the drying gas for drying. However, the existing foaming equipment still has the problems of low foaming efficiency, uneven heating of raw materials and high energy consumption. [0003] ...

AI Technical Summary

Problems solved by technology

However, the existing foaming equipment still has the problems of low foaming efficiency, uneven heating of raw materials and high energy consumption.

[0003] The Chinese patent with the publication number CN201042837 discloses an EPS foaming machine, which includes a feeding mechanism, a foaming tank, a drying bed, connecting pipelines between various components and a control system, and the steam on the foaming tank There are few inlets and steam outlets, low foaming efficiency, and uneven heating of foam particles; the Chinese patent with the publication number CN207140200U discloses a high-efficiency steam pre-foaming machine, which is set by a spiral stirring belt and a mixing barrel, When the device pre-foams the material, the material in the mixing tank can be heated evenly, thereby ensuring the foaming quality of the material. The steam inlet and steam outlet on the mixing tank of the invention are less, and the foaming efficiency is low; Publication No. The Chinese patent of CN201685385U discloses a kind of EPS foam foaming machine with fluidized drying bed, which is connected with steam input pipeline, compressed air input pipeline, cleaning pipeline, sewage pipeline, exhaust pipeline on the foaming tank. pipeline, the fluidized drying bed system is connected to the exhaust pipeline

This invention has no weighing mechanism, the precision is insufficient, and the heat dissipation mechanism of the fluidized drying bed is less, and the heat dissipation effect is poor
