A polyurethane foaming device

Abstract

The invention belongs to the technical field of polyurethane production equipment, specifically a polyurethane foaming device, including a frame body, the right side of the second belt is provided with a first helical spring piece fixedly connected to the upper and lower inner walls of the frame body; A helical spring piece meshes with the first bump; the side of the third belt away from the first helical spring piece is provided with a second helical spring piece fixedly connected to the upper and lower inner walls of the frame; The first helical spring piece is engaged with the second helical spring piece; the first helical spring piece, the second helical spring piece, the first protrusion, the second protrusion and the third protrusion slide against the inner wall of the frame to slide the frame The polyurethane adhered to the inner wall is scraped off, and at the same time, the polyurethane in the frame can be fully stirred, and the stirring is assisted by the first air bag and the second air bag, so that the stirring is more sufficient and 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
