Abstract
The utility model particularly relates to a micro-pulse carbon fiber metering pump, and is used for solving the problem that a filament is easily broken by non-uniform fineness of the filament produced by a glue solution pumped during working of an existing metering pump due to interval pulse. The micro-pulse carbon fiber metering pump comprises an inner cover plate and an outer cover plate, wherein a middle plate fixed with edges of the inner cover plate and the outer cover plate is arranged between the inner cover plate and the outer cover plate, a pump shaft and a driven shaft are arranged between the inner cover plate and the outer cover plate, two pairs of gear sets which are inwards and outwards distributed and staggered in center distances of teeth are arranged between the inner cover plate and the outer cover plate, each pair of gear sets comprises drive gears fixed on the pump shaft and driven gears meshed with the drive gears and sleeved on the driven shaft, and a working cavity partitioning plate fixed with the middle plate is arranged between the two pairs of gear sets. The micro-pulse carbon fiber metering pump is reasonable and reliable in structure design, stable in operation, stable in outlet pressure, and accurate in metering; the produced filaments have no pulse corrugated thin and thick filaments and are not broken in a high-temperature carbonizing process, and thus the product quality is improved.
Description
Technical field
The utility model relates to carbon fibre precursor textile manufacturing machine, relates in particular to metering pump, is specially a kind of micropulse carbon fiber metering pump.
Background technique
The working principle of conventional metered dose pump is the intermediate plate that a pair of gear is arranged on pump, two mutual interlocks of gear in active chamber, and by the rotation of pump shaft, two mutual interlocks of gear are rotated.Spatial volume in the middle of tooth and tooth is equipped with glue, and after being extruded away, the glue volume that often turns tooth and tooth space is exactly the flow that metering pump often turns.But in working gear, the volume interval of tooth and tooth the uniformity of flow, causing pump to push at work the glue of getting has intermittent pulse, thus produce silk have ripple thickness silk, produced filament section.Especially have the carbon fibre precursor of filament section just to have serious fracture of wire situation in 3200 degree high temperature cabonization processes, more easily there is this situation in high-grade carbon fiber wire, goes out the needed high-grade carbon fiber of space flight and aviation national defense construction so be difficult to carbonization.
Summary of the invention
The utility model, in order to solve the glue got in existing metering pump work because intermittent pulse causes the problem of the inhomogeneous and then easy fracture of wire of the silk size produced, provides a kind of micropulse carbon fiber metering pump.
The utility model is to adopt following technological scheme to realize: micropulse carbon fiber metering pump, comprise inner cover plate and outer cover plate, between inner cover plate and outer cover plate, be provided with the intermediate plate fixing with both edges, and between inner cover plate and outer cover plate, be provided with pump shaft and driven shaft, between inner cover plate and outer cover plate, be provided with inside and outside two pairs and distribute and gear train that tooth centre distance staggers, the every pair of gear train is by being fixed on the driving gear on pump shaft and engaging and be enclosed within that driven gear on driven shaft forms with driving gear, between two pairs of gear trains, be provided with the active chamber dividing plate fixing with intermediate plate.
When work, the pump shaft of driven by motor metering pump rotates, and glue is inhaled into active chamber from glue-feeder, and by the extruding of working of inside and outside two gear trains simultaneously, glue flows out from gum exudation mouth.Because of inside and outside gear train tooth top staggered positions, the two-chamber working flow complementation that active chamber dividing plate separates, glue solution flow is stable, outlet pressure does not have pulse ripple, product non-ripple filament section, having overcome the glue of getting in existing metering pump work has intermittent pulse to cause the easily problem of fracture of wire of silk of producing.
The utility model reasonable in design is reliable, the gear train staggering by two groups of tooth centre distance are set, realize the on-stream micropulse of metering pump, metering pump smooth running, outlet pressure is stable, and metering is accurate, the silk no pulse ripple thickness silk of producing, guarantee in high temperature cabonization process not fracture of wire, improved quality of product.
