Abstract

A flow controlling system for filling liquid into the soft packages is composed of a pneumatic diaphragm valve, a regulating motor and a filled quantity control box containing microprocessor control circuit. The regulating screw bolt connected to the output shaft of said regulating motor via a connecting sleeve with a regulating wheel is extended in the limiting screw hole of said pneumatic diaphragm valve. The counting teeth are arranged on the circumference of regulating wheel. The switch for detecting said regulating wheel and the regulating motor are respectively and electrically connected with said microprocessor control circuit.

Description

Technical field: [0001] The invention relates to a liquid flexible packaging machine, in particular to a liquid filling flow control device. Background technique: [0002] At present, the filling flow control of liquid flexible packaging machine is divided into: artesian tank manual adjustment device, plunger pump adjustment device, frequency converter adjustment device. The measurement accuracy of these methods is not high, and is greatly affected by liquid and flow pressure. Due to inaccurate measurement, the qualified rate of packaged products is low, resulting in a lot of waste. Invention content: [0003] The purpose of the present invention is to solve the deficiency of the filling flow control technology of the liquid flexible packaging machine mentioned above, and provide a liquid filling flow control device that greatly improves the measurement accuracy, has a compact and reasonable structure, low cost, and is easy to operate. [0004] The technical solution for...
