Description

Technical Field

[0001] The utility model relates to the technical field of sponge foaming, in particular to a temperature-controllable multi-stage sponge foaming device. Background Art

[0002] Sponge foaming is a process for making sponge materials, especially polyurethane (PU) sponge. The foaming process usually includes the following steps:

[0003] Raw material preparation: The main raw materials of polyurethane sponge are polyol and isocyanate, which are mixed in a specific proportion to form a foaming reaction mixture. In addition, auxiliary materials such as blowing agent, catalyst, stabilizer and cross-linking agent need to be added;

[0004] Mixing: Mix the polyols, isocyanates and other additives evenly in a high-speed mixer. This stage is very critical because uneven mixing will lead to unstable sponge performance;

[0005] Foaming: The mixed materials enter the foaming machine, where they are heated to a certain temperature. At this time, the foaming agent begins to decompose and produce gas, which will be trapped in the material, causing it to expand and form foam;

[0006] Molding: The foamed foam enters the molding mold. As the foam further expands and solidifies, it will cling to the shape of the mold, thus forming a variety of sponge products;

[0007] Vulcanization: Some sponges need to be vulcanized after molding to improve their heat resistance and mechanical strength;

[0008] Cooling and demoulding: When the sponge has finished vulcanizing, it needs to be cooled to set its shape and then removed from the mold.

[0009] At present, when foaming liquid raw materials of sponges, most of them are heated by electric heating elements. However, the heating of electric heating elements is to increase the temperature at a single point and then transfer it to the surroundings. As a result, when heating or cooling is required, it is necessary to wait for the start or shutdown time of the electric heating element, which greatly increases the production time. Therefore, it is necessary to design a sponge foaming processing equipment that can heat evenly and can operate according to the need of heating or cooling. Utility Model Content
