Microwave detection system and microwave detection method for cigarette holder filter stick curing agent content

Abstract

The invention relates to a microwave detection system and a microwave detection method for cigarette holder filter stick curing agent content. The microwave detection system comprises a microwave signal generator, a first isolator, a microwave probe, a second isolator, a detection amplifier, an A / D converter, a signal processor, a data acquisition and processing computer and a display, which are connected in sequence. According to the microwave detection system and the microwave detection method for the cigarette holder filter stick curing agent content, when a filter stick passes through a microwave resonant cavity, since the material density of the filter stick and the content of the curing agent are different, that is, the dielectric constants are different, the resonant frequency and the resonant bandwidth of the microwave resonant cavity are changed; the density of the filter stick material and the content of the curing agent can be analyzed and calculated by accurately measuringchange in the resonant frequency and the resonant bandwidth of the microwave resonant cavity. According to the microwave detection system and the detection method for the cigarette holder filter stickcuring agent content, continuous operation can be conducted in the production process, and online detection can be conducted on the curing agent content of the cigarette holder filter stick rapidly,reliably and safely.

Description

technical field [0001] The invention relates to a microwave detection system and a detection method for the curing agent content of a cigarette holder filter rod. Background technique [0002] The main technical indicators of the filter rod include length, circumference, suction resistance, hardness, roundness, moisture content and some appearance indicators. The amount of glycerin (curing agent) applied in the filter rod molding directly affects the hardness and suction resistance of the filter rod. For filter rods of various specifications, the cigarette factory or material factory checks the weight of each filter rod and the glycerin content in the filter rod The percentage is stipulated. At present, all kinds of molding machines in use do not have the online detection and control technology or device for the distribution uniformity and content of filter rod glycerin. They are all offline detection. Manual adjustment, poor real-time performance, slow process, and large w...

Problems solved by technology

The amount of glycerin (curing agent) applied in the filter rod molding directly affects the hardness and suction resistance of the filter rod. For filter rods of various specifications, the cigarette factory or material factory checks the weight of each filter rod and the glycerin content in the filter rod The percentages are stipulated. At present, all kinds of molding machines in use do not have online detection and control technology or devices for the uniformity of glycerin distribution and content of filter rods. They are all offline detection. The offline detection takes a long time, and only a small amount of random inspection

Manual adjustment, poor real-time performance, slow process, and large waste during the period; manual intervention, poor system

Since the method adopted in the above adjustment process is manual, the adjustment of various parameters is adjusted according to the experience of the operator, and there is no program analysis process solidified by the system, so the parameter adjustment and adjustment range of the unit are different. It's random, not systematic
