There is the inconsistent problem of pipe tobacco flow and throwing speed to current cigarette machine, the utility model provides a pipe tobacco transport control system and method of J17 cigarette machine acquires the pipe tobacco flow of cigarette machine in real time through the controller, and according to the running speed of pipe tobacco flow control first motor to the pipe tobacco of messenger's throwing roller is shed the speed and is accorded with the running speed of cigarette machine. The problems of uneven throwing, low dispersion degree and broken tobacco shreds caused by the fact that the flow rate and the throwing speed of the tobacco shreds of the existing ZJ17 cigarette making machine are inconsistent are solved, the cigarette strip forming quality can be improved, and the cigarette production efficiency is increased.
As shown in fig. 2, a cut tobacco delivery control system of a ZJ17 cigarette making machine comprises: the device comprises a controller, a first frequency converter, a first motor and a wire throwing roller. The output end of the controller is connected with the input end of the first frequency converter, the output end of the first frequency converter is connected with the control end of the first motor, and the controller controls the running speed of the first motor through the first frequency converter. The first motor is used for controlling the rotating speed of the thread throwing roller so that the thread throwing roller throws out the tobacco threads at a corresponding tobacco thread throwing speed, and the tobacco threads are adsorbed and formed by the thread suction belt. The controller is also used for acquiring the tobacco shred flow of the cigarette making machine in real time and controlling the running speed of the first motor according to the tobacco shred flow so as to enable the rotating speed of the shred throwing roller to accord with the running speed of the cigarette making machine.
Specifically, the controller controls the frequency conversion of the first motor through the first frequency converter, so that the rotating speed of the first motor changes, and further the rotating speed of the throwing roller changes, and therefore the tobacco shred throwing speed is adjusted. When the flow of the tobacco shreds is small, the controller controls the rotating speed of the first motor to be reduced, so that the throwing speed of the tobacco shreds is reduced. Therefore, the rotating speed of the tobacco throwing roller can be changed along with the running speed of the cigarette making machine, and the tobacco throwing speed and the tobacco supply quantity are changed in proportion. The problems that the tobacco shreds are broken due to the fact that the tobacco shreds are thrown at a high speed when the flow of the tobacco shreds is small, the tobacco shreds are thrown at a constant speed when the flow of the tobacco shreds is large to cause uneven throwing and low dispersion degree, and tobacco shred groups are not easy to break up are solved, the cigarette strip forming quality can be improved, and the cigarette production efficiency is increased.

Further, the tobacco shred metering device comprises: a weight sensor; the weight sensor is used for detecting the weight variation of the tobacco shreds conveyed by the cigarette making machine, and the controller calculates the tobacco shred flow according to the weight variation.
The system further comprises: an industrial camera; the industrial camera is in signal connection with the controller and is used for photographing the tobacco shreds thrown by the throwing roller to obtain tobacco shred throwing images and transmitting the tobacco shred throwing images to the controller; and the controller determines the dispersion degree of the tobacco shreds thrown by the shred throwing roller according to the tobacco shred throwing image.
If the dispersion degree is smaller than a first threshold value, the controller determines that the tobacco shred throwing speed is smaller than the rotating speed required by the tobacco shred flow, and the controller controls the rotating speed of the first motor to be gradually increased according to a set value until the dispersion degree is larger than the first threshold value.

It should be noted that, when the dispersion degree is small, the number of the cut tobacco clusters is large, and at this time, the rotating speed of the throwing roller is too small, and needs to be adjusted to be large, so that the cut tobacco is thrown more uniformly. When the dispersion degree is large, the tobacco shreds are broken more, and the rotating speed of the throwing roller is too large, so that the tobacco shreds are required to be adjusted to be small so as not to be broken.
The system further comprises: a second frequency converter and a second motor. The second motor is used for controlling the rotating speed of a shred throwing roller of the cigarette making machine, and the controller controls the running speed of the second motor through the second frequency converter. When the degree of dispersion is smaller than the first threshold value, the controller controls the movement rotation speed of the second motor to be gradually increased until the degree of dispersion is larger than the first threshold value.
