As shown in fig. 1, the cigarette packet package sealing degree detection system of the present embodiment includes a detection device 1, and the detection device 1 has a first detection state and a second detection state. The detection apparatus 1 includes a detection vessel 11, a pressure buffer vessel 21, a barometric pressure generator 22, and a pressure measuring device. The detection container 11 comprises a first cavity 111 for placing the cigarette packet 5 to be detected, and in a first detection state, the air pressure in the first cavity 111 and the air pressure in the package of the cigarette packet 5 in the first cavity 111 are adjusted to be first air pressure; the pressure buffer container 21 includes a second chamber 211, and in the first detection state, the second chamber 211 is isolated from the first chamber 111, and in the second detection state, the second chamber 211 is communicated with the first chamber 111 and isolated from the outside; the air pressure generator 22 is adapted to communicate with the second chamber 211 in a first sensing state to adjust the air pressure of the second chamber 211 to a second air pressure different in magnitude from the first air pressure, and to be isolated from the second chamber 211 in a second sensing state. The pressure measuring device is used for measuring the air pressure in the first cavity 111 in the second detection state and forming a measuring result; the control device 7 is in signal connection with the pressure detection device, and the control device 7 is configured to receive and process the measurement result of the pressure detection device to judge the size of the package tightness of the cigarette packets 5.
when the sealing degree of the cigarette packet package is detected, the detection device 1 enters a first detection state, and firstly, the cigarette packet 5 to be detected is placed into the first cavity 111, so that the air pressure in the package of the cigarette packet 5 is balanced with the air pressure in the first cavity 111 to reach a first air pressure. When the first air pressure is local atmospheric pressure, the first cavity 111 can be always communicated with the atmosphere in the process of balancing the air pressure in the package of the cigarette packet 5 and the air pressure of the first cavity 111, so that the pressure in final balancing is the local atmospheric pressure. When the first air pressure is other set pressures, after the cigarette packet 5 is placed in the first cavity 111, the first cavity 111 needs to be sealed to be isolated from the outside, and then negative pressure is pumped out from the first cavity 111 by using a negative pressure source, or positive air pressure is injected into the first cavity 111 by using an air pressure source such as an air pump, so that the air pressure in the package of the cigarette packet 5 and the air pressure in the first cavity 111 finally reach the set balance pressure.
in the first detection state, the second chamber 211 of the pressure buffer container 21 is isolated from the outside, the air pressure generator 22 is communicated with the second chamber 22, and the air pressure in the second chamber 211 is adjusted to a second air pressure different from the first air pressure by decreasing or increasing the air pressure in the second chamber 211. The air pressure generator 22 may be a vacuum pump, an air pump, or the like. The pressure generator 22 may be always connected to the second chamber 211, communicating the pressure generator 22 with the second chamber 211 by setting a valve and then opening the valve, and isolating the two by closing the valve. The pressure producer 22 may also be kept disconnected from the pressure buffer vessel 21 while being isolated from the second chamber 211 and connected to the second chamber 211 when pressure regulation is required. After the air pressure of the second chamber 211 is adjusted to the second air pressure, the air pressure generator 22 is isolated from the second chamber 211 by closing a valve or by being separated from each other, etc., so that the second chamber 211 is kept independent. In the first detection state, the first chamber 111 and the second chamber 211 are isolated from each other, so that the air pressure regulation inside the two chambers is not influenced by each other and is independent from each other.
The air pressure in the first cavity 111 and the package of the cigarette packet located therein reaches the first air pressure of the equilibrium air pressure, and after the second cavity 211 is adjusted to the second air pressure, the first cavity 111 is communicated with the second cavity 211, and the detection device 1 enters the second detection state. Before the first chamber 111 and the second chamber 211 are communicated, the first chamber 111 and the second chamber 211 are required to be sealed, then the first chamber 111 is communicated with the second chamber 211, and the communicated first chamber 111 and second chamber 211 are in a sealed environment isolated from the outside. At the moment when the second cavity 211 is communicated with the first cavity 111, the first cavity 111 and the second cavity 211 reach balance rapidly, the air pressure is changed into a third air pressure, the air pressure change in the cigarette packet package is small, and the air pressure inside and outside the cigarette packet package has pressure difference. In the second detection state, the pressure detection device detects the air pressure in the first cavity 111 under the action of the internal and external pressure difference of the cigarette packet package in real time, and obtains a real-time measurement result. The control device 7 can process the measurement result of the pressure detection device and then judge the air pressure change rate of the first cavity 111 under the action of the air pressure difference between the inside and the outside of the cigarette packet 5 package, so that the sealing degree of the cigarette packet package can be judged. The smaller the sealing degree of the cigarette packet package is, the poorer the sealing of the cigarette packet package is, the faster the pressure difference inside and outside the cigarette packet package is reduced, and the larger the air pressure change rate obtained by a measurement result is; the larger the sealing degree of the cigarette packet package is, the better the sealing of the cigarette packet package is, the slower the pressure difference inside and outside the cigarette packet package is reduced, and the smaller the air pressure change rate obtained by the measurement result is. Therefore, the sealing degree of the cigarette packet package can be judged according to the measurement result of the first pressure measurement unit 3.
The pressure detection device detects the air pressure in the first cavity 111 in real time in the second detection state, and the pressure detection device can be set as a pressure sensor corresponding to the first cavity 111, so that the pressure detection device can detect the air pressure in the first cavity 111 in the first detection state and in the second detection state. The pressure detection device may be further configured as a pressure sensor corresponding to the second chamber 211, and in the first detection state, the pressure detection device cannot detect the gas pressure of the first chamber 111 because the first chamber 111 is isolated from the second chamber 211, and in the second detection state, the first chamber 111 is communicated with the second chamber 211, and because the gas pressure of the first chamber 111 is balanced with the gas pressure of the second chamber 211, the gas pressure of the first chamber 111 may be detected by detecting the gas pressure in the second chamber 211. The pressure detecting device can be a digital pressure sensor with high precision and high response speed, for example, a pressure sensor with precision of 10pa and response speed of 5ms can be selected.
The tobacco bale packing tightness detection system of this embodiment, through setting up pressure buffer container 21, through making second chamber 211 and first chamber 111 of pressure buffer container 21 be linked together, can make atmospheric pressure in first chamber 111 and the second chamber 211 reach the equilibrium fast to can establish pressure differential inside and outside tobacco bale packing fast. Through detecting the change rate of the air pressure around the cigarette packet package under a certain air pressure difference, the sealing degree of the cigarette packet package can be judged quickly and conveniently, meanwhile, the damage to the cigarette packet package can be reduced, and the influence on reusing or selling the detected cigarette packet is reduced.

This arrangement can facilitate and simplify the operation of communication and isolation between the first chamber 111 and the second chamber 211, and/or the operation of communication and isolation between the pressure generator 22 and the second chamber 21. For example, when the first chamber 111 is adjusted to the first air pressure and the second chamber 211 is adjusted to the second air pressure, the first valve 4 is closed, so that the air pressure adjustments of the two chambers can be independent of each other without affecting each other. After the atmospheric pressure regulation in two chambeies is accomplished, when detection device 1 got into the second and detects the state, through opening first valve 4 on the first connecting line, can make first chamber 111 and second chamber 211 communicate in the twinkling of an eye to can make the atmospheric pressure of first chamber 111 and second chamber 211 reach the equilibrium fast, thereby establish atmospheric pressure differential inside and outside the tobacco bale packing in first chamber 111 fast.

The control device 7 is in signal connection with the stepper motor 222. This arrangement controls the movement of the piston rod 221 by controlling the rotation of the stepping motor 222. Meanwhile, when the package tightness of a plurality of cigarette packets 5 is detected, when the air pressure producer 223 is communicated with the second cavity 211 to regulate the air pressure of the second cavity 211, the same distance is moved by controlling the piston rod 221 every time, so that the second air pressure of the second cavity 211 after being regulated every time is ensured to be the same, and the detection precision of the tightness is ensured.
