A Solenoid Valve Drive Circuit for Mixed Feeding with Four Head Weighers

Abstract

The invention provides an electromagnetic valve driving circuit for four-scale mixed feeding. The electromagnetic valve driving circuit comprises a bearing module CZ1 and an electromagnetic valve. An output port of the bearing module CZ1 is connected with the electromagnetic valve YV through a wire. A photoelectric coupling terminal KI used for driving the electromagnetic valve YV is arranged between the output port of the bearing module CZ1 and the electromagnetic valve YV. A circuit on the input side can be effectively and electrically isolated from a circuit on the output side, signals can be transmitted in the form of light, the anti-interference effect is improved, and introduction and impact of intense voltage can be avoided to a certain extent through the circuit on the output side.

Description

technical field [0001] The invention relates to the field of four-head scales, including the research, development and improvement of the voltage regulation and stabilization of four-head scales for weighing, and in particular to a solenoid valve driving circuit for mixed feeding of four-head scales. Background technique [0002] With the advancement of technology and the development of science and technology, the weighing and packaging of products has gradually entered the intensive, large-scale production era. When packaging products, the products must be weighed. At this stage, the four-head weighing scale is 4 It consists of a set of independent weighing systems. Each group of weighing systems uses weighing modules to collect weighing data. The output ports of the weighing modules of this system are output by transistors, which cannot directly drive solenoid valves. The control unit communicates with each sensor and The actuator cannot be well isolated, which increases t...

When packaging products, the products must be weighed. At this stage, the four-head weighing scale is 4 It consists of a set of independent weighing systems. Each group of weighing systems uses weighing modules to collect weighing data. The output ports of the weighing modules of this system are output by transistors, which cannot directly drive solenoid valves. The control unit communicates with each sensor and The actuator cannot be well isolated, which increases the interference of transmission, and at the same time increases the introduction and impact of voltage, causing damage to the solenoid valve and affecting the efficiency of mixed feeding
