Description

Technical Field

[0001] The invention relates to the technical field of sponge foaming nozzles, in particular to a sponge continuous foaming nozzle using liquid carbon dioxide as a foaming agent. Background Art

[0002] The sponge foaming process is to obtain a solid and soft substance through a variety of liquids that can react chemically quickly after mixing. The shorter the time these mixed liquids stay in the foaming nozzle cavity, the less solid blockage will be formed in the nozzle cavity, and the more uniform the density of the sponge will be; the density of the sponge is controlled according to the different raw material formulas and control strips. In addition to the formula of the foaming agent, the cutting gap and smoothness when the nozzle bubble is formed are also key factors, which requires the nozzle's ejection gap to be adjusted quickly and accurately; at the end of each shift, the foaming agent remaining in the foaming nozzle has reacted, and the nozzle must be disassembled and cleaned, otherwise these residues will form hard blockages in the nozzle cavity, causing the quality stability of the sponge produced in the next shift. Therefore, the quality of the nozzle of the foaming equipment determines the quality of the sponge product. The quality of the nozzle is mainly measured by whether the nozzle gap adjustment is accurate and convenient, whether the nozzle is easy to disassemble, and whether the nozzle is easy to clean.

[0003] At present, multi-layer filter shower nozzles and gate rod nozzles are commonly used in sponge continuous foaming equipment that uses liquid carbon dioxide as a foaming agent at home and abroad. Multi-layer filter shower nozzles are prone to nozzle blockage during the production process, affecting the continuity and stability of production; and gate rod nozzles are large in size, and it is difficult to adjust the spray gap of the nozzle each time. Disassembly and cleaning of each shift are time-consuming and labor-intensive, which brings many inconveniences to the operation. Therefore, it is necessary to provide a sponge foaming nozzle with a clever structure that is convenient for adjusting the gap and disassembly and cleaning. Summary of the invention
