Metering type lead screw color master proportional valve

Abstract

The invention discloses a metering type lead screw color master proportional valve which comprises a feeding assembly, a discharging assembly and a mixing valve assembly, wherein the feeding assembly is used for quantitatively conveying a color master in the discharging assembly into the mixing valve assembly; the feeding assembly comprises a motor, wherein the motor drives a feeding lead screw to rotatably feed; the discharging assembly comprises a color master hopper used for storing the color master, a discharging chamber is arranged at the bottom of the color master hopper, and the whole color master hopper is mounted on a horizontal sliding block base; the discharging chamber comprises an inlet and an outlet, wherein a discharging pipe is mounted at the outlet, and the end part of the feeding lead screw is arranged in the discharging pipe after the feeding lead screw extends to the outlet of the discharging chamber from the inlet of the discharging chamber; the mixing valve assembly comprises a static base, wherein the interior of the static base is hollow, a distributing cone with a cavity is arranged in the static base, and a raw material inlet is formed in a position, which corresponds to the position of the top end of the distributing cone, of the top end of a shell of the static base; and an opening communicated with the cavity of the distributing cone is formed in the bottom of the distributing cone.

Description

technical field [0001] The invention relates to a proportional valve assembly, which is specifically used for quantitatively mixing color masterbatch and raw materials. Background technique [0002] For processing lines such as injection molding that include color masterbatch, a proportional valve is set on it to mix the color masterbatch and raw materials quantitatively and then supply them to molding machines such as injection molding machines or presses for molding; quantitative mixing is generally weighing mixing; Since the color masterbatch and raw materials are mostly pellets or granular powder, once the color masterbatch and raw materials are mixed unevenly, it will affect the product quality during the molding process; in order to mix reliably, the existing proportional valve will increase the blowing or stirring mixing. structure, which can produce the effect of mixing materials, but the mixing structure is too complicated, and it is very easy to damage the raw mate...
