Description

Technical Field

[0001] The invention belongs to the technical field of polyurethane foaming machine equipment, and specifically relates to a multi-component polyurethane foaming machine. Background Art

[0002] The full name of polyurethane is polyurethane, which is a polymer compound. Polyurethane has a thermoplastic linear structure. It has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, and has smaller compression deformation. At the same time, it has good heat insulation, sound insulation, shock resistance and anti-toxic properties. It is light in weight, has excellent sound insulation and heat insulation properties, is resistant to chemicals, has good electrical properties, is easy to process, has low water absorption, is oil-resistant, wear-resistant, low-temperature-resistant, aging-resistant, has high hardness and is elastic. Polyurethane can also be used to make adhesives, coatings, synthetic leather, etc. Polyurethane needs to be foamed during the preparation process, so a foaming machine is needed. Most existing polyurethane foaming machines use a simple single stirring rod for stirring, and the stirring efficiency is low. At the same time, most polyurethane foaming machines can only produce single-component polyurethane, which leads to low polyurethane production efficiency, greatly increases production costs, and reduces corporate profits.

[0046] The working steps of the multi-component polyurethane foaming machine are as follows:

[0048] 2) After the raw materials are mixed in the material input mechanism 10;

[0049] 3) After the mixing is completed, the upper telescopic support rod 11 contracts, so that the lower end of the material feeding mechanism 10 is closely fitted with the upper end of the foaming mechanism 8.
