Abstract

The invention provides a polyurethane sponge preparation and processing technology, and relates to the technical field of polyurethane sponge preparation and processing. The polyurethane sponge preparation and processing technology comprises a bottom plate, a clamping device and a slitting device, wherein the clamping device is fixedly installed on the bottom plate, and the slitting device is arranged on the clamping device. The polyurethane sponge preparation and processing technology can solve the following problems that a, an existing polyurethane sponge preparation and processing technology is not stable enough to clamp the cylindrical sponge, and the cylindrical sponge is easy to incline and separate during rotation; and b, the existing polyurethane sponge preparation and processing technology cannot change the slitting thickness when the cylindrical sponge is slit, and only can slit the polyurethane sponge with one thickness.

Description

technical field [0001] The invention relates to the technical field of polyurethane sponge preparation and processing, and specifically proposes a polyurethane sponge preparation and processing technology. Background technique [0002] Sponge, a porous material with good water absorption and elasticity, can be used for cleaning, product packaging or as a cushion. Commonly used sponges are wood cellulose fibers, natural sponges made from spongy animals or expanded plastic polymers, and synthetic sponges made from three other materials: low-density polyether, polyvinyl alcohol, and polyurethane. [0003] Among them, polyurethane sponge is widely used. Polyurethane sponge has the advantages of softness, low density, good resilience, and small compression permanent deformation. It is widely used in the fields of automobiles, shoe materials, furniture, clothing, and decorative materials. Therefore, polyurethane sponge The preparation technology is also constantly improving. At p...
