Thin spinning metering pump

Abstract

The invention discloses a thin spinning metering pump, and belongs to the technical field of spinning mechanical equipment. The thin spinning metering pump is of a one-inlet multi-outlet structure, and sequentially comprises a pump plate, a gear plate, a cover plate and a driving shaft penetrating through the cover plate and the gear plate from bottom to top, the number of the pump plate is one, the number of the gear plate is one, a planetary gear train is arranged in the gear plate, a sun gear is driven by rotation of a motor, and accurate control over materials is achieved through meshing of the sun gear and a planetary gear. Compared with a traditional metering pump, the thickness of the metering pump is greatly reduced, the needed machining materials are few, the machining technology is simple, the machining cost is low, and meanwhile disassembly, assembly and replacement are more convenient in the using process.

Description

technical field [0001] The invention belongs to the technical field of spinning machinery and equipment, and in particular relates to a spinning metering pump with a single-layer gear plate structure. Background technique [0002] Spinning machine refers to the mechanical equipment that processes polymer solution or polymer melt to form filaments through spinning technology. During the spinning process, polymer solution or polymer melt first passes through the metering pump and is filtered through the filter. Send it into the spinneret, and then spray the filamentous fluid from the spinneret holes on the spinneret, and put the filamentous fluid into a coagulation bath, and the fluid will be solidified into a solid filament, and then cleaned or stretched. Closing means the completion of the entire spinning process. [0003] During the spinning process, the metering pump controls the flow rate and entry speed of the polymer solution or polymer melt into the spinneret holes in...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the spinning metering pump usually has a multi-layer structure, and the multi-layer structures work together to realize the metering process, but the metering pump with a multi-layer structure is thicker, heavier, and the installation, maintenance and disassembly process is inconvenient; At the same time, the metering pump with multi-layer structure is difficult to process and consumes a lot of materials, so the production and processing costs are high
