Detailed Description
In order to make the solution of the embodiment of the present invention better understood by those skilled in the art, the embodiment of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
Aiming at the problem that the current cigarette making machine has uncoordinated tobacco shred flow rate and tobacco shred throwing speed, the invention provides a tobacco shred conveying control system and method of a J17 cigarette making machine, which are used for acquiring the tobacco shred flow rate of the cigarette making machine in real time through a controller and controlling the running speed of a first motor according to the tobacco shred flow rate so as to enable the tobacco shred throwing speed of a shred throwing roller to be consistent with the running speed of the cigarette making machine. Solves the problems of uneven throwing, low dispersity and broken tobacco shreds caused by uncoordinated tobacco shred flow and throwing speed of the traditional ZJ17 cigarette machine, can improve the forming quality of tobacco shreds and increase the production efficiency of cigarettes.
As shown in fig. 2, a cut tobacco conveying control system of the ZJ17 cigarette making machine includes: 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 tobacco throwing roller so that the tobacco throwing roller throws tobacco shreds out according to the corresponding tobacco shred throwing speed, and the tobacco shreds are adsorbed and formed by the tobacco sucking 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 tobacco shred throwing roller to be consistent 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 running speed of the first motor is changed, and the rotating speed of the throwing roller is changed, thereby realizing the adjustment of the throwing speed of the tobacco shreds, and when the flow rate of the tobacco shreds is large, the controller controls the running speed of the first motor to be increased, so that the throwing speed of the tobacco shreds is increased. When the flow rate of the tobacco shreds is small, the controller controls the running speed of the first motor to be reduced, so that the throwing speed of the tobacco shreds is reduced. Therefore, the rotation speed of the cut tobacco throwing roller can be changed along with the running speed of the cigarette making machine, and the throwing speed of cut tobacco is ensured to be changed in proportion to the cut tobacco supply. The problems of uneven throwing, low dispersity and difficulty in scattering tobacco clusters caused by high-speed throwing when the flow rate of the tobacco shreds is small and the tobacco shreds are crushed due to high-speed throwing when the flow rate is large are avoided, the forming quality of the tobacco rod can be improved, and the production efficiency of cigarettes is improved.
The system further comprises: a tobacco shred metering device; the tobacco shred metering device is arranged in a metering trough of the cigarette making machine and is used for detecting tobacco shred flow of the cigarette making machine and transmitting the tobacco shred flow to the controller.
Further, the tobacco shred metering device comprises: a weight sensor; the weight sensor is used for detecting the weight change of the tobacco shred conveyed by the cigarette making machine, and the controller calculates the tobacco shred flow according to the weight change.
The system further comprises: an industrial camera; the industrial camera is in signal connection with the controller and is used for photographing cut tobacco thrown by the tobacco throwing roller to obtain a cut tobacco throwing image, and transmitting the cut tobacco throwing image to the controller; and the controller determines the dispersity of the cut tobacco thrown by the cut tobacco throwing roller according to the cut tobacco throwing image.
And if the dispersity is smaller than a first threshold value, the controller determines that the cut tobacco throwing speed is smaller than the rotating speed required by the cut tobacco flow, and the controller controls the running speed of the first motor to be gradually increased according to a set value until the dispersity is larger than the first threshold value.
And if the dispersity is larger than a second threshold value, the controller determines that the cut tobacco throwing speed is larger than the rotating speed required by the cut tobacco flow, and the controller controls the running speed of the first motor to be gradually reduced according to a set value until the dispersity is smaller than the second threshold value, and the second threshold value is larger than the first threshold value.
In practical application, the dispersity of the image is obtained by carrying out image processing on the cut tobacco throwing image acquired by the industrial camera, wherein the calculation of the dispersity can be compared by setting standard images corresponding to different dispersities, so as to calculate the dispersity corresponding to the cut tobacco throwing image acquired currently. When the degree of dispersion is small, the number of the tobacco clusters is large, and at the moment, the rotation speed of the tobacco throwing roller is too small, and the adjustment is needed to be large, so that the tobacco throwing is more uniform. When the dispersity is large, the tobacco shreds are crushed more, and the rotating speed of the tobacco throwing roller is too high, so that the adjustment is required to be reduced, and the tobacco shreds are not crushed.
The system further comprises: a second frequency converter and a second motor. The second motor is used for controlling the rotating speed of the wire-flicking roller of the cigarette making machine, and the controller controls the operating speed of the second motor through the second frequency converter. When the dispersity is smaller than the first threshold value, the controller controls the operation speed of the second motor to be gradually increased until the dispersity is larger than the first threshold value. When the dispersity is greater than the second threshold, the controller controls the operation speed of the second motor to gradually decrease until the dispersity is less than the second threshold.
The system further comprises: a third frequency converter and a third motor. The third motor is used for controlling the conveying speed of the cut tobacco sucking belt of the cigarette making machine, and the controller controls the running speed of the third motor through the third frequency converter. When the operating speed of the second motor increases or decreases, the controller controls the operating speed of the third motor to increase or decrease with the operating speed of the second motor.
In practical application, the running speed of the thread-flicking roller and the running speed of the thread-sucking belt are matched with the rotation speed of the thread-throwing roller, if the rotation speed of the thread-flicking roller is large, the flow of the cut tobacco can be increased, the rotation speed of the thread-throwing roller can not throw out the cut tobacco, and the cut tobacco is easy to throw unevenly. If the conveying speed of the silk suction belt is too low, the scattered cut tobacco can not be absorbed by the silk suction belt in time, and the blockage is caused.
