Glycerinum spraying system based on PLC

Abstract

The invention discloses a glycerinum spraying system based on a PLC, belongs to the technical field of basic control systems, and particularly relates to improvement of the glycerinum spraying system based on the PLC.The glycerinum spraying system based on the PLC is stable in operation and uniform in glycerium spraying.The glycerinum spraying system based on the PLC is characterized in that a pressure sensor and a temperature sensor are connected with the input end of the PLC through an analog-digital conversion module, and a touch screen, an atomizing switch of an atomizer, a liquid level detection switch of a liquid level detector and an original point proximity switch are connected with an input port of the PLC; an output port of the PLC is connected with a main heater and a preheater through a heating relay, the output port of the PLC is connected with a booster pump and a petrol pump through a petrol pumping relay, and the output port of the PLC is connected with a strand movement host switch through a host interface relay; the output port of the PLC is connected with a servo motor through a servo amplifier, and the servo motor controls a valve.

Description

technical field [0001] The invention belongs to the technical field of basic control systems, and in particular relates to an improvement of a PLC-based glycerin spraying system. Background technique [0002] The glycerin gluing system of the filter rod forming unit is the key device to control the hardness of the filter rod. It is the key to control the hardness of the filter rod to control the synchronous change of the glycerin spraying amount and the tow running speed in real time, and to maintain the stability of the glycerin spraying amount on the tow per unit area. factor. The traditional gluing method uses the centrifugal force of the brush rotation to spray glycerin on the surface of the moving tow in the form of small droplets. The particle size of the small droplets is not uniform, and the rotation speed of the brush is not synchronized with the running speed of the tow. Realize the even spraying of glycerin, can't guarantee the stability of filter rod hardness, c...

Problems solved by technology

The traditional gluing method uses the centrifugal force of the brush rotation to spray glycerin on the surface of the moving tow in the form of small droplets. The particle size of the small droplets is not uniform, and the rotation speed of the brush is not synchronized with the running speed of the tow. The uniform spraying of glycerin cannot guarantee the stability of the filter rod hardness, resulting in a large amount of waste of tow and a large amount of waste filter rods
