Abstract

The invention discloses a precise high-pressure polyurethane foaming machine. The foaming machine comprises a base, material bins and a mixing box; a first support is mounted at the top of the base; acontrol box is mounted at the top of the base; and the material bins are mounted at the top of the first support. According to the foaming machine, by the aid of a first pressure pump and a first pressure gauge which communicate with the mixing box as well as second pressure pumps and second pressure gauges which communicate with the two material bins, raw materials in the mixing box and the material bins can be stirred and pressurized respectively, the raw materials in the two material bins are stirred and pressurized preliminarily, are fluffy due to the internal gas, are conveyed into an inner barrel of the mixing box and are mixed for stirring and pressurizing again, the volumes of the two groups of fluffy raw materials are enlarged, the contact area of the raw materials is increased,mixing of the raw materials is promoted, meanwhile, the secondary pressure can be adjusted according to the state of the raw materials after preliminary pressurizing, by the aid of the foaming procedure of secondary pressurizing, the phenomenon of insufficient foaming can be avoided, the raw materials are ensured to be foamed completely, foam is fine and uniform, and the machine is suitable for wide popularization and use.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a precision polyurethane high-pressure foaming machine. Background technique [0002] Polyurethane is a kind of polymer compound, its full name is polyurethane, and it can be made into polyurethane plastic, polyurethane fiber, polyurethane rubber and elastomer. The device is a kind of foaming equipment that makes the aqueous solution of the foaming agent reach a certain concentration. Some existing polyurethane high-pressure foaming machines mix the raw materials and pressurize once to achieve foaming, but the raw materials are prone to vortex when they are stirred, which increases the local pressure, and the high pressure may cause uneven foaming of the raw materials. Therefore, we propose a precision polyurethane high pressure foaming machine. Contents of the invention [0003] The object of the present invention is to provide a precision polyurethane high-pressure foaming machine,...
