Description

Technical Field

[0001] The present invention relates to the field of sponge foaming machines, and in particular to a sponge foaming machine capable of lifting the foaming height. Background Art

[0002] In most sponge production processes, the one-step box foaming method is adopted. Various raw materials are rapidly added to the forming box under high-speed stirring, and reactions such as chain growth, foaming, crosslinking, and curing are completed in the forming box to complete the sponge production. When the sponge is foaming, the rising height of the upper end surface is not limited. Therefore, the height of the foamed sponge will rise freely and exceed the height of the top of the foaming box, resulting in the overflow of the foaming box and easily causing waste of sponge materials. For this reason, a sponge foaming machine capable of lifting the foaming height is proposed. Summary of the Invention
