Latest Patents

One of Koike's latest patents is for a hot melt applicator and nozzle used therefor. This invention includes a nozzle opening, a valve seat disposed upstream of the nozzle opening, and an empty chamber formed between the nozzle opening and the valve seat. The design features a valve body that is movable to the valve seat, allowing it to be opened or closed, and a spring that biases the valve body. A pneumatically driven cylinder is utilized to drive the spring, enhancing the applicator's performance. The valve body is shaped like a cone, with an apex angle facing the nozzle opening, while the valve seat has a tapered surface that contacts the cone. This innovative design prevents leakage when the valve is closed and minimizes the creation of glue filaments, particularly for high-viscosity adhesives.
