The application provides an automatic temperature control method and device of a cigarette beauty device, which feed back whether the temperature of a soldering iron is uniformly distributed or not by utilizing the surface temperature of a cigarette at the outlet of the beauty device after beauty treatment, and heat different heating pipes by different heating powers so as to expect that all positions of the soldering iron reach temperature balance, thereby avoiding the quality problem caused by uneven heating of the soldering iron.
As shown in fig. 1, the automatic temperature control system of the cigarette beauty treatment device provided by the present application comprises a beauty treatment part, a temperature measurement part, a PLC controller 15 and an upper computer in signal connection with the PLC controller, wherein a touch screen 16 is arranged on the upper computer.
The beauty part comprises an upper iron plate and a lower iron plate which have the same structure and are large in plane. Taking a cauterizing plate 1 at the lower part as an example, as shown in fig. 1, four heating pipes with the same structure are uniformly installed on the cauterizing plate 1 on the lower plane along the longitudinal direction (perpendicular to the running direction of the cigarette packet), a first heating pipe 2, a second heating pipe 3, a third heating pipe 5 and a fourth heating pipe 6, and the four heating pipes extend along the transverse direction (parallel to the running direction of the cigarette packet) of the cauterizing plate 1. A horizontal tubular platinum resistor 4 is installed at the middle position of the soldering iron plate 1 and used for detecting the temperature of the soldering iron plate 1.
The temperature measuring part comprises an upper temperature measuring bracket and a lower temperature measuring bracket which are parallel to the iron plate. Taking the lower temperature measurement bracket 7 as an example, as shown in fig. 1, three platinum chip resistors, namely a first platinum chip resistor 8, a second platinum chip resistor 9 and a third platinum chip resistor 10, are uniformly distributed on the temperature measurement bracket 7 along the longitudinal direction and serve as temperature sensors, and each platinum chip resistor forms a temperature measurement area. Preferably, as shown in fig. 1, each temperature sensor is located in a region between two adjacent heating pipes in the longitudinal direction. Thermal insulation materials are arranged between the temperature measuring support and the corresponding soldering iron plates and are connected with each other through bolts, so that the temperature of the soldering iron plates is prevented from generating large interference on the detection of the platinum chip resistors.
The platinum resistor patch (with the thickness of about 2mm, for example) is fixed on the inner surfaces of the upper temperature measurement bracket and the lower temperature measurement bracket through glue, and the platinum resistor patch is flush with the plane of the temperature measurement bracket after being installed.
The cigarette carton enters the beauty treatment part under the pushing of the cigarette pushing device of the packaging machine equipment, enters between the upper temperature measurement bracket and the lower temperature measurement bracket after being ironed and shaped by the iron plates on the upper large plane and the lower large plane, then enters into the cigarette carton conveying channel and is conveyed to the next procedure.
As shown in fig. 2, each heating pipe is connected with a solid-state relay, i.e., a first solid-state relay 11, a second solid-state relay 12, a third solid-state relay 13, and a fourth solid-state relay 14. The PLC 15 is in signal connection with the four solid-state relays, drives the solid-state relays to conduct corresponding heating pipes, and heats the soldering iron plate, so that the temperature of the soldering iron reaches an ideal value. A cigarette detection channel is formed between the two temperature measurement brackets, and a cigarette in-place sensor (for example, an optical fiber type photoelectric detector) is arranged at the inlet of the cigarette detection channel. The PLC 15 is in signal connection with the cigarette in-place sensor and is used for receiving the cigarette in-place signal. The PLC 15 is also in signal connection with the tubular platinum resistor 4 and the patch platinum resistors 8, 9 and 10 and is used for acquiring temperature information. The PLC controller 15 also receives a reset signal and a running signal of the packing machine.
The touch screen 16 is used for displaying the temperature detected by the tubular platinum resistor 4 and the patch platinum resistors 8, 9 and 10 and setting the preset temperature of the iron plate. The two planes are provided with analog quantity signals of 6 paster platinum resistors, each paster platinum resistor independently detects the temperature value of each cigarette, and the temperature values of three point positions of each cigarette are displayed in real time through corresponding interfaces of the touch screen. And as the equipment runs, the subsequent cigarettes continuously enter the detection channel, and a continuous cigarette temperature curve is formed and displayed on the touch screen.
Based on the automatic temperature control system, the application provides an automatic temperature control method of a cigarette beauty device, which is suitable for a PLC (programmable logic controller).
After the automatic temperature control system is powered on, the soldering iron plate enters a preheating stage, and no cigarette carton enters the beauty device in the stage. The PLC acquires platinum resistor analog quantity signals of the tubular platinum resistor 4 and calculates the real-time temperature of the iron plate. And then, heating and controlling the soldering iron plate according to the preset temperature and the real-time temperature.
Specifically, as an embodiment, the PLC controller controls the four heating pipes to heat the soldering iron plate with the same heating power through the four solid-state relays, respectively, until the temperature of the soldering iron plate reaches a preset temperature.
As an embodiment, all heating tubes are heated based on the heating power of one of the heating tubes. For example, the heating power of the second heating tube 3 is taken as a reference, and the heating powers of the four heating tubes are kept consistent until the temperature detected by the tubular platinum resistor 4 is consistent with the preset temperature. The heating control at this stage adopts a PID feedback control mode. The smaller the difference value between the real-time temperature of the iron plate and the preset temperature is, the smaller the heating power of all the heating pipes is. The larger the difference value between the real-time temperature of the iron plate and the preset temperature is, the larger the heating power of all the heating pipes is.
After the preheating is finished, the cigarette beauty device enters a normal working state. At this time, as shown in fig. 3, the PLC controller performs the following automatic temperature control method:
s310: receiving temperature information of a plurality of temperature measurement areas on two opposite sides of the cigarette to be ironed.
After the cigarette carton enters the beauty treatment part for ironing and shaping, the cigarette carton in-place sensor detects a cigarette carton signal, the cigarette carton corresponding to the position is just ironed by a plane iron, and the central position of the whole cigarette carton is just positioned in three temperature measurement areas. The three platinum resistors 8, 9 and 10 measure the temperature of the upper end surface or the lower end surface of the strip box, record the temperatures as T1, T2 and T3 respectively through an internal register of the PLC controller, and display the temperatures on the touch screen in real time.
S320: whether the temperature difference between two adjacent temperature measurement areas exceeds a first threshold value is judged, namely whether the absolute value of the temperature difference between any two of the temperatures T1, T2 and T3 exceeds the first threshold value (for example, 1 ℃). If yes, go to S330; otherwise, S340 is performed.
S330: if the absolute value of the temperature difference of one group of temperatures exceeds a first threshold value, which indicates that the temperature of the whole iron plate is in an unbalanced and stable state, each solid-state relay is controlled to apply different heating powers to different heating pipes on the iron plate of the cigarette beauty device, so that the surface temperature of the whole iron plate reaches a balanced state.
As an embodiment, the heating power of other heating pipes is calculated by taking the temperature of one of the platinum chip resistors and the heating power of one of the heating pipes as references.
For example, at the temperature T of the second platinum-on-chip resistor 9 2 On the basis of the acquisition of T 1 、T 2 And T 3 The four heating pipes are applied with different heating powers by adopting a heating control principle of linear fitting once on the basis of considering the positive correlation between the temperature of the soldering iron plate and the heating power of the heating pipes. Specifically, the power of different heating pipes satisfies the following formula:
and meets the condition of linear fitting
Wherein, P i The heating power of the ith heating tube is indicated, i =1, 2, 3, 4.P is 2 The heating power of the second heating pipe 3 is shown. And controlling the heating power of the heating pipe according to the conduction time of the heating pipe in unit time. K is j Correlation coefficient, T, of temperature detection value representing jth platinum-patch resistance measurement j Denotes the temperature of the jth platinum patch resistance measurement, j =1, 2, 3.T is 2 Indicating the temperature measured by the second platinum patch resistor 9. For different heating pipes, the correlation coefficients of the platinum resistors of the same patch are different. An example is given below:
the PLC obtains the heating power of each heating pipe according to the formula (1) and controls the four heating pipes to heat.
S340: if the absolute value of the temperature difference between any two of T1, T2 and T3 is smaller than the first threshold value, the temperature of the whole iron plate reaches a stable state of balance. In order to avoid overshoot, the heating power of each heating tube is heated according to the previous heating power.
Preferably, if the temperature difference between at least one of T1, T2 and T3 exceeds a second threshold (typically 5 ℃), an abnormality is considered to exist, which may cause a disconnection failure in a heating tube or cause a large deflection of the upper and lower soldering iron planes, resulting in an excessively small local pressure on the surface of the cigarette carton. At the moment, the PLC controller gives an alarm.
When the cigarette in-place sensor cannot detect a cigarette signal, the temperature measurement part automatically stops temperature acquisition, and when the cigarette is detected to enter again, the temperature measurement part re-measures the temperature and displays the temperature value, and finally displays continuous temperature values on the touch screen.
When no cigarette enters the beauty device, each heating pipe maintains the heating power determined by the correlation coefficient corresponding to the previous cigarette to operate.
And after the system is electrified again every time, the heating coefficient of the heating pipe is automatically calibrated and calculated again according to the detected temperature of the cigarettes in the preset number.
There is certain difference between the temperature that tubulose platinum resistance and paster platinum resistance measured, in order to ensure the accuracy that temperature detected, the automatic temperature control system of this application possesses the temperature calibration function, can realize through automatic or manual mode.
Manual function: the calibration is performed manually based on the difference between the temperature T4 measured by the tubular platinum resistor 4 and the temperature T2 measured by the second platinum patch resistor 9. Assuming that the temperature T4 measured by the tubular platinum resistor 4 is 100 c and the temperature T2 measured by the second platinum patch resistor 9 is 90 c, the system reduces the temperature measurement of T4 by 10 c to 90 c by manually inputting a calibration value of-10 c to facilitate temperature matching of the two.
The touch screen is also provided with a manual temperature setting function, in a manual mode, an operator can manually set the surface temperatures of the upper plane and the lower plane of the cigarette carton according to needs, the T2 temperature is taken as a reference, deviation values are increased or reduced, for example, the T1 temperature is set to be +2 ℃, at the moment, the automatic temperature control system cancels the automatic adjustment function, the T2 temperature value minus 2 ℃ is manually taken as the temperature value of T1 to be substituted into the linear fitting model, and the heating power of the four heating pipes is automatically adjusted; otherwise, the temperature T1 is set to-2 ℃, and the temperature T2 plus the temperature 2 ℃ is used as the temperature value of T1. The range of the set value in the manual setting interface cannot exceed +/-5 ℃, and the touch screen interface is limited by the upper limit value and the lower limit value of the input value.
The automatic calibration function: and (3) automatically reading the temperature T2 value measured by the second patch platinum resistor 9 for 10 times each time when the power is on, calculating an average value, finally matching the temperature value T4 corresponding to the tubular platinum resistor 4 into the average value, and automatically completing calibration in the program.
Preferably, when the parallelism of the upper and lower iron plates is not adjusted in place and the deviation is small (within a reasonable range), the automatic temperature control system increases the temperature of the position with small pressure on the iron, compensates through the temperature, and ensures the transparent paper to be flat, stiff and smooth through temperature compensation so as to improve the overall wrapping quality of the transparent paper of the cigarette carton.
