Negative pressure automatic regulating system for material-feeding and cigarette-rod-forming machine of cigarette maker

Abstract

The invention relates to a negative pressure automatic regulating system for a material-feeding and cigarette-rod-forming machine of a cigarette maker. The negative pressure automatic regulating system comprises a pneumatic control valve installed on each set of cigarette maker, two negative pressure sensors, a control unit, an industrial control computer mounted on the cigarette maker and another industrial control computer mounted on a wind dedusting system. The pneumatic control valve is installed on a negative pressure air duct of the material-feeding and cigarette-rod-forming machine and replaces an original hand-operated control valve; the two negative pressure sensors are respectively mounted on the negative pressure air duct at positions before and after the pneumatic control valve; and the signal of an interlock switch of an air compartment of the material-feeding and cigarette-rod-forming machine is connected to the control unit. The negative pressure automatic regulating system provided by the invention can realize automatic opening and closing of the negative pressure valves of the material-feeding and cigarette-rod-forming machine and automatic adjusting of the value of negative pressure so as to stabilize the negative pressure value of the material-feeding and cigarette-rod-forming machine, so the purposes of saving energy and improving tobacco rod quality are achieved and remote management and control of negative pressure of the cigarette maker are realized.

Description

technical field [0001] The invention relates to a method for automatically adjusting the negative pressure of a cigarette machine feeding and forming machine, in particular to a negative pressure automatic adjusting system for a cigarette machine feeding and forming machine. Background technique [0002] PRPTOS cigarette making machine is the mainstream model of cigarette making machine in the tobacco industry. The function of the feeding and forming machine is to loosen the cut tobacco sent by the cut tobacco system, remove iron, impurities, stalks, sign, and then make cut tobacco rods that meet the unit length of cigarettes and reach the target weight and send them to the rolling forming machine. The negative pressure system of the feeding rod forming machine uses negative pressure air to absorb the shredded tobacco on the suction ribbon to form a shredded tobacco rod. The size and stability of the negative pressure are the key factors that determine the quality of cigaret...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above deficiencies in the prior art of cigarette making machines, and provide a method for automatically adjusting the negative pressure of the cigarette machine feeding and forming machine. The negative pressure valve of the strip forming machine cannot be opened and closed automatically, and the negative pressure value can be automatically adjusted. At the same time, the remote management and control of the negative pressure of the cigarette making machine can be realized.
