Cigarette quality detection system and detection method

Abstract

The invention discloses a cigarette quality detection system. The cigarette quality detection system comprises a cigarette forming assembly, a chopper device, a cigarette direction adjusting device, aPLC, a microwave scanner, an encoder, an optical fiber detector and an electromagnetic valve, wherein the microwave scanner, the encoder, the optical fiber detector and the electromagnetic valve areelectrically connected with the PLC. The cigarette quality detection method comprises the steps that the microwave scanner continuously scans a cigarette bar to form a voltage signal and transmits thevoltage signal to the PLC; when the PLC judges that the unqualified cigarettes appear according to the voltage signals, the PLC judges the serial numbers of the unqualified cigarettes; and the PLC locates the unqualified cigarettes and outputs a control signal to enable the electromagnetic valve to be communicated with a compressed air pipe and a compressed air spray head to blow out the unqualified cigarettes. The problem that an existing compound machine does not have a product quality detection function, so that unqualified products flow into a downstream procedure is solved, and the product percent of pass of heated non-combustible cigarettes is increased.

Description

technical field [0001] The invention relates to the technical field of cigarette quality detection, in particular to a cigarette quality detection system and a detection method. Background technique [0002] The hollow heat-not-burn cigarette is a new type of heat-not-burn cigarette. figure 1 As shown, the hollow tube is a hollow tube made of three layers of cigarette paper, and the main function of this part is to adjust the suction resistance, improve the hardness of the heat-not-burn cigarette, and ensure the molding effect. The production process of hollow heat-not-burn cigarettes: 1. Prefabricated mouthpiece (left section), hollow tube (middle section), sliced ​​tobacco section (right section); 2. Complete hollow tube and sheet with the first compound machine The splicing of the shredded tobacco segments forms the cigarette segment; 3. The second compounding machine is used to complete the splicing of the mouthpiece and the cigarette segment; so far, the hollow heat-no...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a cigarette quality detection system and detection method, which are used to solve the problems of large splicing gaps, hollow tubes and shredded tobacco that often occur when the composite machine splices and rolls hollow tubes and shredded tobacco sections in the prior art. In order to improve the product qualification rate of heat-not-burn cigarettes, there are quality problems such as segment splicing reverse and hollow tube rupture, and the problem of unqualified products flowing into downstream processes due to the lack of corresponding detection functions
