AI Technical Summary

Technical Problem

Existing nitrocellulose pressing equipment is prone to filter clogging during the air extraction process, which affects the safety and efficiency of subsequent compression and air extraction.

Method used

A nitrocellulose pressing device was designed. A servo motor drives a transmission rod to drive a drive gear, which in turn drives a driven gear and a fixed rod to rotate. A rubber rod beats the filter screen, which moves up and down with the help of a spring to clean the attached materials. At the same time, a rack drives a pressing plate to move to perform the pressing operation.

Benefits of technology

This technology enables the nitrocellulose to be compressed while the filter screen is being cleaned, ensuring effective oxygen removal and improving equipment safety and operational efficiency.

Abstract

The utility model relates to the technical field of nitrocotton compression, and discloses nitrocotton pressing equipment which comprises a compression box, a box door is rotatably installed at the front end of the compression box through a hinge, an air extractor is fixedly installed at the upper end of one side of the compression box, the air extraction end of the air extractor is communicated with an exhaust pipe, and the other end of the exhaust pipe is communicated with a processing box. According to the technical scheme, the driven gear can drive the fixed rod to rotate, the rubber rod on the fixed rod can rotate along with the fixed rod, the rubber rod continuously knocks the filter screen, the filter screen is driven to move up and down in a reciprocating mode in cooperation with the spring on the filter screen, and therefore attachments below the filter screen are cleaned; according to the device, a rack can be driven to move rightwards, so that the effect of discharging oxygen in nitrocotton is guaranteed, a rack can also drive an extrusion plate to move rightwards, the extrusion plate is made to press the nitrocotton in a compression box, then the effect of pressing the nitrocotton while cleaning a filter screen is achieved, and therefore subsequent nitrocotton pressing operation is facilitated.
