[0002] At present, conveying devices for high-viscosity materials such as adhesives, polyurethane, butyl rubber, and hot-melt adhesives at home and abroad generally use gear pumps, plunger pumps, screw pumps or diaphragm pumps to transport them. When the viscosity of the above materials is very high, gears are used alone. Pumps, plunger pumps, screw pumps or diaphragm pumps are not easy to convey, or are not easy to meter and convey, and the metering is inaccurate

Abstract
The invention discloses a combined adhesive supplying device using a gear pump and a screw pump, and relates to a device for metering, conveying and supplying high-viscosity materials such as adhesive, polyurethane and hot-melt adhesive, in particular to a polyurethane metering, conveying and supplying device. The combined adhesive supplying device comprises a pedestal, cylinders, an adhesive barrel, a sealing ring, a gland, a screw pump, a gear pump, a fixing plate, a speed reducer, a servo motor, connecting rods, a cross beam and the like, wherein the screw pump comprises a pump body, a screw rod and a screw; the servo motor and the speed reducer are fixedly connected with a fixing plate sequentially; the gear pump is fixed on the screw pump; the lower end of a shaft of the gear pump is connected with the upper end of the screw rod through a shaft coupler A; a suction opening of the gear pump is positioned at an outlet end of the screw pump; an inlet end of the screw pump is positioned at a conical adhesive feeding opening of the gland. When the viscosity of the polyurethane or the adhesive is relatively high, metering and conveying can be easily controlled and metering is accurate; the combined adhesive supplying device can be also used for metering and conveying the polyurethane, the adhesive, the hot-melt adhesive, foam materials, grease, ink, silicon sulfide resin or other high-viscosity materials.
Description
technical field [0001] The invention relates to a glue supply device for measuring and conveying high-viscosity materials such as adhesives, polyurethanes and hot melt adhesives, in particular to a glue supply device for polyurethane metering and conveying. Background technique [0002] At present, conveying devices for high-viscosity materials such as adhesives, polyurethane, butyl rubber, and hot-melt adhesives at home and abroad generally use gear pumps, plunger pumps, screw pumps or diaphragm pumps to transport them. When the viscosity of the above materials is very high, gears are used alone. Pumps, plunger pumps, screw pumps or diaphragm pumps are not easy to deliver, or are not easy to meter and deliver, and the metering is inaccurate. Contents of the invention [0003] In order to solve the above problems, the present invention provides a combined glue supply device of a gear pump and a screw pump, which solves the problems of conveying high-viscosity materials suc...
