Description

Polyurethane foaming machine is used in production of imitative wooden furniture

Technical Field

The invention relates to the technical field of foaming devices, in particular to a polyurethane foaming machine for producing wood-like furniture.

Background

The soft Polyurethane (PU) mainly has a thermoplastic linear structure, has better stability, chemical resistance, rebound resilience and mechanical property than PVC foaming materials, and has smaller compression deformability. Good heat insulation, sound insulation, shock resistance and gas defense performance. Therefore, the product is used as a packaging, sound insulation and filtering material. [2] The hard PU plastic has the advantages of light weight, excellent sound insulation and heat insulation performance, chemical resistance, good electrical property, easy processing and low water absorption rate. It is mainly used as a heat-insulating structural material in the building, automobile and aviation industries. [2] The polyurethane elastomer has the performance between that of plastic and rubber, and has the advantages of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. Is mainly used in the shoe making industry and the medical industry. The polyurethane can also be used for preparing adhesives, coatings, synthetic leather and the like. Two raw materials are often used in the production process of wood-like furniture and are put into a device to be mixed, and a polyurethane foaming machine is used when foaming is carried out.

Two pan feeding mouths have been seted up on the top of the jar body to current polyurethane foaming machine need be followed when using, and drop into different materials in two pan feeding mouths, can adopt agitating unit to mix it when two kinds of materials drop into jar internal portion simultaneously and foam the operation again, but because it has partly to demonstrate the foaminess when the material gets into jar internal portion, adopt traditional mode this moment to enable two kinds of materials when stirring it and take place to mix, but the mobility of foam generally is less than the mobility of rivers, so the inhomogeneous condition of mixing has appeared when having led to the fact, influence the foaming effect.

When two materials enter the interior of the tank body, the two materials are mixed by the mixing device, but the materials incline in the tank body due to poor flowability of the materials during foaming, so that the weight distribution of the tank body is not uniform, the tank body is easy to incline, and once the tank body inclines, a part of the materials cannot be contacted with the mixing device, so that the foaming effect is poor.

Since the temperature inside the can body is also very important in the foaming operation, the existing device generally installs a heating device inside the can body to heat the material inside the can body, but the temperature of each position of the material inside the can body is different due to the fixed position of the heating device, which is very easy to affect the quality of the material.
