Stirring device for polyurethane foam machine

Abstract

The invention discloses a stirring device for a polyurethane foaming machine. The stirring device comprises a shell, a stirrer and a motor, wherein the shell is of a hollow structure provided with a feed opening and a discharge opening; the stirrer is arranged in the shell and comprises a first stirring part and a second stirring part which are sequentially arranged in series from the feed opening to the discharge opening; the first stirring part comprises a first shaft and stirring blades which are arranged around the axial direction and extend around; the second stirring part is provided with an S-shaped second shaft; the first shaft and the second shaft are arranged axially and rotatably; and the motor drives the first shaft. The stirring device disclosed by the invention is simple in structure, stable in foaming process, sufficient in stirring and uniform and moderate in bubble size, and is suitable for large-scale production of various polyurethane foamed materials.

Description

technical field [0001] The invention relates to the technical field of polyurethane production equipment, and mainly relates to a stirring device for 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 t...

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
