[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.

[0039] As Figures 1 to 3As shown, this embodiment provides a cigarette packaging material detection device, which includes: a bottom plate 1, a first reference seat 2, a driving mechanism 4, a clamp 5, a conveying component, a glue applicator 6, a glue spray valve, a heating component, a pressure sensor 7, an industrial camera 8 and a controller. The first reference seat 2 is installed on the bottom plate 1, and a workbench 3 is convexly provided on the first reference seat 2. The first test piece is laid on the table surface of the workbench 3. The clamp 5 is used to clamp and fix the second test piece. The driving mechanism 4 includes a driving member 41 and a rotating shaft 42. The clamp 5 is fixedly connected to the rotating shaft 42, and the driving member 41 can drive the rotating shaft 42. The conveying assembly is installed on the bottom plate 1, and the conveying assembly can drive the glue applicator 6 to spray glue on the first piece to be tested. The glue spraying valve is used to open or close the glue nozzle of the glue applicator 6. The conveying assembly can drive the heating assembly to press the second piece to be tested, so that the second piece to be tested is bonded to the first piece to be tested. The pressure sensor 7 is used to detect in real time that the table surface of the workbench 3 is subjected to the pressure of the heating assembly. The shooting end of the industrial camera 8 is facing the table surface of the workbench 3. The controller is connected to the heating assembly, the conveying assembly, the glue spraying valve, the pressure sensor 7 and the industrial camera 8. Specifically, the driving member 41 is a cylinder, and the first piece to be tested and the second piece to be tested are both cigarette trademark papers. With such arrangement, during the inspection, after the glue applicator 6 accurately sprays glue on the first piece to be tested, the driving member 41 drives the clamp 5 to move so that the second piece to be tested is bonded to the first piece to be tested, and the heating component applies pressure and heats the second piece to be tested. Then the driving member 41 continues to drive the clamp 5 to move, so that the second piece to be tested is separated from the first piece to be tested, and the material bonding part of the two is left on the table surface of the workbench 3. The industrial camera 8 takes a picture of the material bonding part and feeds it back to the controller in real time. The controller calculates and determines the water absorption capacity of the cigarette label paper or the bonding capacity of the water-based glue for cigarettes. It can detect the quantitative indicators of the key characteristics of the cigarette packaging materials before being put on the machine in real time, so as to guide the operator to make targeted adjustments to the subsequent on-machine equipment, improve the production and processing efficiency, and effectively reduce the unqualified rate of the finished cigarettes to ensure the quality of the finished products.

[0040] Specifically, the process of the cigarette packaging material detection device provided in this embodiment detecting the water absorption capacity of cigarette label paper or the bonding capacity of cigarette water-based adhesive is further described in detail below.

[0041] S100: Lay the first test piece on the table surface of the workbench 3, and glue the upper surface of the first test piece by the glue applicator 6, wherein the glue spraying amount can be precisely controlled by the controller controlling the opening and closing of the glue spraying valve.

[0042] S200: Clamp and fix the unglued second test piece on the fixture 5, and the driving member 41 drives the fixture 5 to act, so that the first test piece and the second test piece are attached and overlapped. Then, the heating assembly presses and heats the second test piece (wherein, the heating temperature, time and pressure can all be adjusted by the controller). At the same time, the pressure sensor 7 real-time feeds back the pressure of the heating assembly on the second test piece to ensure that the state when the tobacco packaging material is put on the machine can be simulated during the detection.

[0043] S300: After the heating assembly finishes heating, the driving member 41 continues to drive the fixture 5 to act, separates the first test piece and the second test piece that are bonded together, and leaves the material bonding part of the two on the tabletop of the workbench 3.

[0044] S400: The industrial camera 8 takes pictures of the material bonding part of the first test piece and the second test piece and feeds them back to the controller in real time. After being calculated by the controller, the ratio of the bonding area to the specified area (fixed) is obtained, and then the water absorption capacity of the tobacco label paper or the bonding capacity of the tobacco water-based glue is determined.

The first connecting member 16 is connected between the support frame 14 and the heating electric iron 15. The heating electric iron 15 is used to press the second test piece so that the second test piece is bonded to the first test piece. Further, the controller is communicatively connected to the heating electric iron 15 to control the heating temperature and time.

[0050] Optionally, in order to ensure that the heating electric iron 15 has a certain buffering effect when pressing the second test piece and avoid excessive impact force of the heating electric iron 15 on the panel 9 causing it to break and shatter, the heating assembly further includes a plurality of guide posts 17, a plurality of elastic members 18, a plurality of limiting members 19, a first fixing block 20, and a second fixing block 21.
