Liquid pouring device for automatic liquid packaging machine

摘要

PURPOSE: A fluid injector of an automatic liquid packing machine is provided to improve the quality by automatically injecting liquid material into the package with installing an auxiliary tank in the main tank, and to clean conveniently by separating a cover of the auxiliary tank. CONSTITUTION: An auxiliary tank(50) is installed in the lower part of a main tank(10), and composed of a liquid inlet, a liquid supply port(52) protruded in the lower part and a cover part(54) mounting an air discharge pipe(53) separably combined with the upper part. The liquid supply port of the auxiliary tank is combined with a liquid discharge port(12) of the main tank, and fluid is injected to transferred package(2) with isolating liquid of the main tank from liquid of the auxiliary tank. An opening valve(30) is opened by a controller(20) in transferring the package under a liquid injection pipe(40), and packing is performed automatically with repeatedly supplying liquid from the auxiliary tank to the package according to internal pressure of the auxiliary tank. Convenience is improved with inputting regular opening time of the opening valve to the controller and cleaning the auxiliary tank by separating the cover part.
