Embodiment

[0038] Taking flavoring in the cigarette production process as an example, the present invention is further described in detail:

[0039] Cigarette manufacturing process: It consists of three main processes: silk making (raw material processing), coiling (rolling molding), and packaging (packaged finished product); among them, flavoring is one of the main processes of cigarette silk making technology. Uniform application and saving raw materials are the key; this device can be used to control the addition of this flavor liquid material in the process of making cigarette shreds;

[0040] refer to figure 1 , when the control device of the present invention performs specific work, it is directly connected to the production line of cigarette shreds and the server of the control center of the production line to form a control system. The specific method is:

[0041] figure 1 The motor in the motor acts as a liquid essence flow rate control pump. The essence passes through its in...

Abstract

The invention discloses a precision control method and a precision control device for adding micro-liquid. The precision control device comprises an ARM9 processor, a color LCD display touch screen, an Ethernet interface circuit, a high-precision speed regulation circuit, a speed monitoring circuit, a flow detection circuit, a liquid level monitoring circuit, an alarm circuit, an SD card interface circuit, a USB interface circuit, a PWMDAC circuit, an SDRAM memory circuit, a program memory circuit flash, and a motor control interface circuit, wherein the circuits are mutually connected and the precision control for adding the micro-liquid addition is realized by software programming. By using the rate tracking technology to timely change the needed liquid flow, the precision control method and the precision control device for adding the micro-liquid realize the accurate control of micro-liquid addition in the production process, achieve the control precision of 1 percent, and have thefunctions of local automatic alarm and remote automatic alarm under the abnormal condition. The precision control method and the precision control device have convenient control parameter input, and can be organically integrated with the conventional production equipment to greatly improve the production efficiency and save the production cost.

Description

technical field [0001] The invention relates to the technical field of industrial automation equipment, in particular to a control method and device for precise liquid addition. Background technique [0002] In some processing enterprises, liquid micro-addition is an important link, for example: in the process of filter tip and shredded tobacco preparation in cigarette factories, liquid raw materials such as flavors and other liquids with different flow rates should be added according to needs; the flow of liquid should be done automatically according to the production speed of the production line Fine adjustment. During the production process, when the speed of the host equipment in the production line rises, because the liquid flow of the traditional liquid control unit equipment cannot be adjusted with the speed increase, the quality does not meet the requirements during the rise of the host equipment in the production line. At different stations and stages of production...
