Polyurethane foaming device

Abstract

The invention belongs to the technical field of polyurethane production devices, and concretely relates to a polyurethane foaming device. The device comprises a frame body, and a first helical springleaf fixedly connected to the upper inner wall and the lower inner wall of the frame body is arranged at the right side of a second belt; the first helical spring leaves is engaged with first projections; a second helical spring leaf fixedly connected to the upper inner wall and the lower inner wall of the frame body is arranged at one side, away from the first helical spring leaf, of a third belt; and second projections are respectively engaged with the first helical spring leaf and the second helical spring leaf. The first helical spring leaf, the second helical spring leaf, the first projections, the second projections and the third projections slide over the inner wall of the frame body in order to scrape off polyurethane adhered to the inner wall of the frame body and sufficiently stir the polyurethane in the frame body; and a first airbag and a second airbag assist to stir in order to achieve sufficient stirring, so the foaming efficiency of the polyurethane is accelerated.

Description

technical field [0001] The invention belongs to the technical field of polyurethane production equipment, in particular to a polyurethane foaming device. Background technique [0002] 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 guardrails, etc. . [0003] Some technical solutions of polyurethane foaming devices have also appeared in the prior art, such as a Chinese patent with application number 2014107507820, which discloses a polyurethane foaming machine, including a shell, a feeding device, and an umbrella nozzle; The umbrella-shaped shower head includes a cone, whose lower end surface is fixed on the inner surface of the spray surface of the umbrella-shaped shower head, ...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art and solve the problems of insufficient stirring, low foaming efficiency and polyurethane adhesion to the shell, a polyurethane foaming device proposed by the present invention uses the first helical spring piece, the second helical spring piece, the first The first bump, the second bump and the third bump slide against the inner wall of the frame to scrape off the polyurethane adhered to the inner wall of the frame, and at the same time fully stir the polyurethane in the frame, pass through the first air bag and the second air bag, Assist in stirring to make the stirring more fully and accelerate the foaming efficiency of polyurethane
