The sponge can be packaged in a compound way according to the requirements of customers, heated, processed, blasted, perforated and the like. Polyurethane sponge has a plurality of air cell structures, but the air permeability is not very strong, and sponge blocks with different types and densities are required to be uniformly coated with glue and compounded together. The traditional method adopts a manual brush to smear, so that the working efficiency is low and the labor intensity is high; some enterprises also adopt a spraying method to spray glue, and the defects are that: the atomized glue splashes in the air, which causes environmental pollution and has a certain influence on the health of people. The compounded sponge needs to be pressed manually, so that the glue and the sponge are fully bonded, then the manual packaging and the sleeving of the sponge are carried out, all the assembly line operations are separated, the efficiency is seriously affected, robots are adopted in some enterprise assembly lines to replace the manual work, and the input cost is greatly increased while the automation is realized, so that a set of glue rolling composite assembly line with high automation degree, low cost and high efficiency is necessary to design.
