Problems solved by technology

[0003] The traditional air-blown polyurethane foaming machine uses a metering pump to inject polyurethane material A and material B into the mixing head at a set ratio and flow rate. When the one-way valve of the mixing head is opened, material A and material B are mixed in the mixing head. The mixed head is blown out by compressed air and injected into the mold to produce finished products. However, the polyurethane foaming process of the traditional air-blown polyurethane foaming machine is extremely unstable, resulting in poor molding accuracy of the produced polyurethane foam material, which is difficult to produce Produce high-quality finished products

Abstract

The invention discloses a polyurethane foaming machine which comprises a shell, a feeding device and injection holes, wherein the feeding device is an umbrella-shaped sprayer; the umbrella-shaped sprayer comprises a cone; the lower end surface of the cone is fixedly arranged on the inner side surface of the spraying surface of the umbrella-shaped sprayer; the tip end of the cone extends to the opposite direction of the spraying surface of the umbrella-shaped sprayer; the cross section of the cone is a triangle of which the side length has a radian; and the injection holes are uniformly distributed in the spraying surface at the periphery of the cone. The polyurethane foaming machine disclosed by the invention is simple in structure, stable in foaming process, full in stirring and uniform and moderate in bubble size and is applied to large-scale production of multiple polyurethane foaming materials.

Description

technical field [0001] The invention relates to the technical field of polyurethane production equipment, in particular to a polyurethane foaming machine. Background technique [0002] At present, with the continuous improvement of people's living standards, polyurethane foam materials are widely used in many fields such as production and life, such as polyurethane insulation materials, polyurethane shutter doors and windows, polyurethane tiles, polyurethane composite glass, polyurethane furniture, polyurethane flower pots and polyurethane guardrail etc. In these industries, the production equipment of polyurethane foam materials used mostly adopts air blowing and mixing polyurethane foam equipment. This type of equipment is widely used due to its low price, low technical difficulty and low maintenance cost. [0003] The traditional air-blown polyurethane foaming machine uses a metering pump to inject polyurethane material A and material B into the mixing head at a set rat...
