Background

In the cigarette production process, the filter stick produced in the forming workshop needs to be conveyed to a rolling workshop through a transmitting pipeline. The specific working mode is that the filter stick transmitter in the forming workshop transmits the filter sticks produced by the forming machine to the filter stick receiver in the rolling workshop through a pipeline by air pressure, and the receiver receives and collects the filter sticks and then supplies the filter sticks to a cigarette making machine for rolling and connecting to produce cigarettes.

The filter stick transmitter is connected with the receiver through a pipeline, the transmitter sets the transmitting air pressure through adjustment, certain pressure is formed in the pipeline, namely the transmitting line speed of the filter stick in the pipeline is changed, and the filter stick is pushed to the receiver at a high speed. Because the receiving speed of the receiver for receiving the transmission of the filter stick is in a certain range, when the transmitting air pressure is too high, the speed of the transmission line is too high, and exceeds the receiving speed range of the receiver, the quality and other problems of a contact, wrinkles and a disordered stick can occur, and the normal conveying of the filter stick is directly influenced; when the emission air pressure is too low, the problems of pipe blockage and the like caused by the fact that the emission speed of the filter stick is too slow and the emission pressure is too low are easily caused, and the guarantee of online supply of the filter stick in cigarette production is directly influenced.

In order to realize the matching of the sending speed of the filter stick of the transmitter and the receiving linear speed of the filter stick required by receivers of different models, the method adopted by each cigarette factory at present is a mode of repeatedly adjusting the air pressure of a transmitter module, the PDCA tracking observation and correction debugging are carried out by observing the sending/receiving stability conditions of the filter stick of the receiver and the transmitter for a long time until the sending air pressure of the transmitter module is matched with the required linear speed of the receiver, and the debugging work is time-consuming, labor-consuming and unintuitive.

According to the linear velocity of the filter stick in the pipeline measured by the velometer, debugging personnel are intuitively guided to adjust the air pressure of the filter stick transmitted by the transmitter, the linear velocity of the filter stick in the pipeline is quickly controlled within the optimal linear velocity receiving range matched with receivers of different models, the problems of pipe resistance of a series of filter stick transmission, high failure rate of the transmitter and the receiver and waste of a large number of filter sticks in the filter stick transmitting/receiving link caused by the fact that the linear velocity of the filter stick in the pipeline is not matched with the linear velocity received by the receiver are greatly reduced, and the guarantee rate of online supply of the filter sticks in cigarette production is effectively improved.
