Technical Field
The utility model relates to the field of tobacco quality control, in particular to online detection equipment for the glycerol content of tows on a filter rod forming machine.
Background
In the filter rod production process, a certain amount of plasticizer is required to be uniformly added into the tows, so that a certain net structure is formed among the opened tows, and the filter rod can reach enough hardness after solidification. The glycerol triacetate (glycerol) is a common plasticizer for acetate fiber filter sticks, and the content of the glycerol needs to be controlled in the normal production process, and the content of the glycerol in the filter sticks directly influences the hardness, the suction resistance, the pressure drop and the like of the filter sticks, so that the filtering efficiency of the acetate fiber filter sticks and the smoking quality of cigarettes are influenced. For various specifications of filter rods, the tobacco or materials factory has a specification for the weight of each filter rod and the percentage of glycerin in the filter rod. The content of glycerol is an important index in quality control of acetate fiber filter sticks. In order to ensure that the glycerol content in the filter stick meets the process standard requirements, the glycerol content in the filter stick needs to be detected regularly.
At present, all the forming machines used in the prior art have no online detection control technology or device for the glycerin weight of the cigarette filter stick, and the online detection is performed off-line, so that the time required by the off-line detection is long, and only a small amount of spot inspection is performed. At present, most filter rod manufacturers adopt a weight method to measure the plasticizer content in acetate fiber filter rods, and a dry-wet rod weighing test method is to take 30 wet rods (filter rods which are normally produced) and 30 dry rods (filter rods which do not contain plasticizers) when a filter rod forming machine runs at high speed, respectively measure the weight average value of 10 groups, calculate the content of glyceryl triacetate according to a formula, and determine whether the process requirements are met. The dry and wet rod weighing test method is simple and effective, but has low accuracy, the test process is greatly dependent on manpower, a large number of filter rods are required to be consumed, the labor intensity is high, and the loss of the filter rods is serious. The spraying amount of the curing agent is manually adjusted, the real-time performance is poor, the process is slow, the waste caused during the process is large, the manual intervention is performed, and the systematicness is poor. The adjustment of various parameters is carried out manually in the adjustment process, so that the adjustment of various parameters is carried out according to the experience of an operator, and a program analysis process of system solidification does not exist, so that the adjustment of the parameters of a unit and the adjustment range are very random, and the system is not systematic.
