Flattening roller spacing detection method for tobacco stem flattener

Abstract

The invention provides a flattening roller spacing detection method for a tobacco stem flattener. The detection method comprises the following steps that: (1), a tobacco stem flattener is started; (2), five flexible metal wires are placed in an entrance vibration slot in parallel at equal intervals along the length direction of a constant-pressure roller, wherein the five flexible metal wires are perpendicular to the constant-pressure roller; (3), the entrance vibration slot is opened and the plurality of flexible metal wires enter the space between the constant-pressure roller and a dynamic-pressure roller through the entrance vibration slot; and after the extruding, the processed metal wires are taken out from a discharge outlet; (4), the thickness between two extruding surfaces of each extruded flexible metal wire is measured; and (5), as long as the difference value between one thickness and the standard value exceeds the technological standard in the step (4), a tobacco stem flattening thickness adjusting plate is processed by fine tuning; and the above four steps are repeated until the difference value between the thickness value of the two extruding surfaces of each flexible metal wire and the standard value meets the technological standard requirement. According to the detection method, the flattening roller spacing is determined by measuring the thickness between the extruding surfaces of each extruded flexible metal wire; the measurement precision is high and the measurement speed is fast; and the practicability is high.

Description

technical field [0001] The invention relates to a method for detecting the thickness of stem pressing in the cigarette industry, in particular to a method for detecting the distance between pressing rollers of a stem pressing machine. Background technique [0002] In the cigarette processing and shredding production line, the stem pressing process refers to extruding the rehydrated tobacco stems to a certain thickness during the tobacco stem processing process, so as to provide good technological conditions for subsequent stem cutting, so that the cut stems The shredded tobacco is closer to the shape of shredded tobacco, which is beneficial to improve the utilization rate of cut stems and the quality of burning and smoking. [0003] At present, the tobacco stems are all processed by a stem pressing machine. The core working part of the stalk pressing machine is a pair of pressure rollers, namely the fixed pressure roller and the dynamic pressure roller. The distance between...

Problems solved by technology

The feeler gauge is composed of measuring sheets of different thicknesses. During the measurement process, the thickness of the stem is measured by sheets of different thicknesses, and the feeler gauge method can only measure the distance between the two ends of the pressure roller, but not the distance between the pressure rollers. Therefore, this method has the disadvantages of low measurement accuracy, time-consuming and laborious, and unsafe operation.
