A plasticizing device for nitrocellulose

Abstract

This utility model relates to the field of nitrocellulose plasticizing technology and discloses a nitrocellulose plasticizing device, including a plasticizing platform. A plasticizing mold is fixedly installed at the top center of the plasticizing platform, and a positioning and liquid collection mechanism is installed inside the plasticizing mold. The technical solution of this utility model involves an extrusion rod installed on one side of a limiting ring that moves synchronously downwards with the extrusion seat. A push rod is fixedly installed at the bottom of the extrusion rod via a linkage plate, and a piston is installed at the top of the push rod. This allows the piston to move downwards within the sealed cylinder, supplying negative pressure to the negative pressure pipe inside the sealed cylinder. Since the other end of the negative pressure pipe is connected to a connecting groove, and the top of the connecting groove is interconnected with the plasticizing mold through multiple sets of through holes, not only can the nitrocellulose inside the plasticizing mold be positioned under negative pressure during the continuous downward movement of the extrusion seat, but the extruded solvent can also be collected as the extrusion seat continuously squeezes out the solvent from the nitrocellulose, ensuring that the plasticized nitrocellulose remains in a dehydrated state.
