Embodiment approach

[0030] As an embodiment of the present invention, the first bump 12, the second bump 16 and the third bump 10 are all inclined; the surfaces of the second belt 11, the third belt 15 and the fourth belt 19 are provided with Groove 4, the first bump 12, the second bump 16 and the third bump 10 are located in the groove 4 respectively, and are connected with the bottom of the groove 4 by the spring 41; , The second bump 16 and the third bump 10 make the stirring more complete, and the foaming rate of the polyurethane is faster, through the setting of the spring 41, and the first bump 12 and the third bump 10 squeeze the extruding plate 3 during rotation , so that the extrusion plate 3 shakes, so that the polyurethane in the frame body 1 flows, the stirring effect is enhanced, and the foaming of the polyurethane is accelerated.

Abstract

The invention specifically relates to an improved foaming process for polyurethane, belonging to the technical field of polyurethane production. A polyurethane foaming machine used in the process comprises a frame body; a first spiral spring piece fixedly connected with the upper and lower inner walls of the frame body is arranged on the right side of a second belt; the first spiral spring piece is engaged with first bumps; the side, away from the first spiral spring piece, of a third belt is provided with a second spiral spring piece fixedly connected with the upper and lower inner walls of the frame body; and second bumps are separately engaged with the first spiral spring piece and the second spiral spring piece. Through sliding of the first spiral spring piece, the second spiral springpiece, the first bumps, the second bumps and third bumps on the inner wall of the frame body, polyurethane adhered onto the inner wall of the frame body is scraped off, and polyurethane in the framebody can be fully stirred at the same time; and since a first air bag and a second air bag are used for assisting in stirring, so 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, in particular to an improved polyurethane foaming process. 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,...
