Description

Technical Field

[0001] The invention relates to the technical field of physical quantity measurement of novel cigarettes, in particular to a fully automatic novel cigarette comprehensive test bench. Background Art

[0002] Natural smoke cigarettes are one of the new categories of cigarettes. They are a new category of tobacco products built to adapt to the new development of tobacco products. The physical parameter information of natural smoke cigarettes is of great significance for the improvement of cigarette design and the optimization of production process. The State Administration for Market Regulation and the National Standardization Administration have formulated a series of conditions and specifications for tobacco production and testing, with the main indicators including weight, circumference, length, draw resistance, etc.

[0003] As a new type of cigarette, natural smoke cigarettes are characterized by the addition of a hollow filter section to the cigarette, and the use of side punching to allow air to enter the cigarette from the side, thereby changing the smoke composition. At present, there is a lack of instruments on the market that can effectively detect the physical parameters of natural smoke cigarettes, especially the inability to detect related parameters such as the end-face closed draw resistance and punching quality of simulated human smoking cigarettes. For the weight, circumference, length, conventional draw resistance and other parameters of natural smoke cigarettes, they are more often tested with the help of single-function test instruments or non-compatible test instruments; and for the end-face closed draw resistance and punching quality of natural smoke cigarettes, they mainly rely on the stability of the online laser punching equipment, and the judgment criteria for punching are also based on the subjective smoking feedback of professionals, and it is impossible to intuitively judge the quality of punching through data parameters.

[0071] 5. The middle hollow groove of the upper block of the test bench feed module has a notch diameter for the tobacco end face that is larger than the notch diameter of the filter end face, which can greatly reduce the cigarette jamming of the feed module, improve the detection efficiency, and reduce the frequency of failures.

[0076] 10. Before testing the sample, the suction resistance detection module of the test bench will use the vacuum generator to suck part of the probe cavity to form a negative pressure, and judge whether the latex tube used to cover the sample is damaged based on the stability of the negative pressure, etc., thereby improving the accuracy of the suction resistance measurement results, reducing manual judgment, and saving time and effort.

[0077] 11. After the sample is tested and falls into the next test module, the suction resistance test module of the test bench will open the solenoid valve switch to allow compressed air to enter the probe cavity through the lower sliding block, thereby blowing out impurities such as tobacco inside the cavity and improving the accuracy and repeatability of the measurement results.

Specifically, an annular sealing ring is also provided on the second wedge-shaped portion 5611 to ensure the sealing effect and the accuracy of the adsorption detection module.

[0178] Before testing the sample to be tested, the suction resistance detection module 5000 of this embodiment will suck part of the probe cavity through the vacuum generator 5801 to form a negative pressure, and judge whether the latex tube used to cover the sample is damaged based on the stability of the negative pressure, etc., thereby improving the accuracy of the suction resistance measurement results, reducing manual experience judgment, and eliminating the need to manually disassemble the probe to check the status of the latex tube, saving time and effort.

[0179] See also Fig. 27 The suction resistance detection module 5000 also includes an air circuit unit 5800, which includes a vacuum generator 5801, a digital negative pressure gauge 5802, a first differential pressure sensor 5803, a valve island 5804, an air source 5805, solenoid valve MV1, solenoid valve MV2, solenoid valve MV3, solenoid valve MV4, solenoid valve MV5, solenoid valve MV6, solenoid valve MV7, and solenoid valve MV8.

[0184] The lower sliding block 5310 is connected to the atmosphere through the solenoid valve MV3;

[0185] The external detection point is connected to the bottom of the lower sliding block 5310 through the electromagnetic valve MV2, and a first differential pressure sensor 5803 is also provided at the external detection point.

[0186] Specifically, the detection process of the sample to be tested in the absorption resistance detection module 5000 is as follows:

[0187] ① Before the sample to be tested enters the suction resistance detection module 5000, the solenoid valve MV5 is opened, the vacuum generator 5801 starts working, the solenoid valve MV2 is closed, and the solenoid valve MV1 is opened. A negative pressure will be formed inside the probe cavity of the two pipelines of the middle clamp block 5420 and the lower clamp block 5320. If there is no leakage point, the negative pressure will tend to stabilize, so as to detect whether there is any leakage in the latex tube covered on the middle clamp block 5420 and the lower clamp block 5320. At the same time, the solenoid valve MV7 is opened, and the front end of the needle cylinder 5700 pops out.

[0188] ② After the sample to be tested enters the suction resistance detection module 5000, it stays at the front end of the needle cylinder 5700. The latex tubes on the middle clamp block 5420 and the lower clamp block 5320 are wrapped around the surface of the sample to be tested. The CFO in the pipeline forms a stable airflow of 17.5 mL / s under the action of the negative pressure generator, and the solenoid valve MV2 opens.

[0189] ③ The solenoid valve MV6 opens, and the telescopic cylinder 5620 works, driving the probe sealing block 5610 to move, so that the lower part of the probe cavity is sealed. When detecting the open suction resistance, the solenoid valve MV3 opens, and the solenoid valve MV8 closes, allowing air to flow in from the side of the sample and the end face of the tobacco; when detecting the side closed suction resistance, the solenoid valve MV3 and the solenoid valve MV8 are closed, allowing air to flow in from the end face of the sample tobacco; when detecting the end face closed suction resistance, the solenoid valve MV3 is closed, and the solenoid valve MV8 is opened, allowing air to flow in from the side of the sample. The sub-control system collects relevant data from the differential pressure sensor and transmits the data to the main control system. After the data is processed, the corresponding open suction resistance value, side closed suction resistance value and end face closed suction resistance value are displayed on the display 1100, and the solenoid valves MV5, MV6 and MV7 are closed, and the sample to be tested falls to the punching detection module 6000;

[0190] ④ Solenoid valves MV2, MV3 and MV8 are closed, and solenoid valve MV4 is opened. The compressed air in the air source enters the detection chamber through the lower sliding block 5310 to blow away impurities such as tobacco, thereby improving the accuracy and repeatability of the measurement results.

[0191] It should be noted that, compared with traditional cigarettes, natural smoke cigarettes require the use of a dedicated heating device when smoking, inserting the tobacco end into the heating device, and when inhaling, air enters the cigarette filter from the side holes, so when judging the quality of cigarettes, it is necessary to detect the suction resistance value when the tobacco end face of the cigarette is closed. In this embodiment, the upper sealing tube 5500 in the suction resistance detection module 5000 can be set to achieve the sealing of the tobacco end face of the natural smoke cigarette. By controlling the on and off of the solenoid valve MV8, the upper sealing tube 5500 is sealed, and air only enters the cigarette from the side holes, thereby obtaining the suction resistance value when the tobacco end face of the cigarette is closed, which is an important basis for judging the quality of cigarettes.

[0201] Specifically, the detection process of the sample to be tested in the punch detection module 6000 is as follows:

[0202] ① Before the sample to be tested enters the punching detection module 6000, the left-right moving cylinder 6500 extends, driving the clamping sliding module 6400 to move to the bottom of the sample channel 6300. At the same time, the output end of the front-back moving cylinder 6406 extends, and the output end of the up-and-down moving cylinder 6404 moves upward, driving the material blocking cylinder 6409 to the bottom of the material receiving position of the punching rotary clamp 6410.

[0203] ② After the sample to be tested passes through the sample channel 6300, it falls to the punching rotary clamp 6410 and the backlight block 6411, and stays on the material blocking cylinder 6409. The telescopic end of the left-right moving cylinder 6500 retracts, driving the clamping sliding module 6400 to move to the best imaging position of the camera 6700; the backlight source 6413 is turned on, the punching rotary clamp 6410 clamps the sample to be tested, and the stepper motor is started, driving the punching rotary clamp 6410 to rotate one circle and then stop.

[0204] ③ The backlight source 6413 is turned off, the up-and-down moving cylinder 6404 moves downward, the forward-and-backward moving cylinder 6406 retracts, the punching and rotating clamp 6410 releases the sample to be tested, and the sample to be tested falls into the collection module 7000.

[0205] ④ The cleaning solenoid valve is controlled to open, and compressed air is used to blow away tobacco, dust and other impurities on the material blocking cylinder 6409 and the punching rotary clamp 6410 through the blowing holes of the material blocking blowing block 6414 and the clamp blowing block 6415.

[0206] See also Fig.31, is a flow chart of the control system of this embodiment. When the entire integrated test bench is working, the sample detection sensor at the bottom of the feed module 2000 detects whether there is a sample to be tested falling. When the sample falls into the weight detection module 3000, a signal is sent to the overall control system, and the overall control system assigns a number to the sample to be tested.

[0207] The weight detection data of the sample to be tested is measured by the weighing scale 3400 in the weight detection module 3000, and is sent to the main control system through the sub-control system of the weight detection module 3000 and stored behind the above-mentioned assigned number.

[0208] Then, the sample detection sensor at the bottom of the weight detection module 3000 monitors the sample to be tested falling to the circumference and length detection module 4000 and sends it to the main control system through the sub-control system of the circumference and length detection module 4000.

[0209] After the circumference measuring instrument 4900 and the length measuring instrument 4800 in the circumference and length detection module 4000 detect the sample to be tested, the corresponding circumference and length measurement data are input into the sub-control system of the circumference and length detection module 4000 through the measuring instrument controller, and then input into the main control system through the sub-control system, and stored behind the above-mentioned assigned number.

[0210] Then, the sample detection sensor at the bottom of the circumference and length detection module 4000 monitors the sample to be tested falling to the suction resistance detection module 5000 and sends it to the main control system through the sub-control system of the circumference and length detection module 4000.

[0211] After the pressure difference sensor in the resistance to suction detection module 5000 detects the sample to be tested, the corresponding resistance to suction detection data is sent to the main control system through the sub-control system of the resistance to suction detection module 5000 and stored behind the assigned number.

[0212] Then, the sample detection sensor at the bottom of the suction resistance detection module 5000 monitors the sample to be tested falling to the punching detection module 6000 and sends it to the main control system through the sub-control system of the suction resistance detection module 5000.

[0213] After the camera 6700 in the perforation detection module 6000 takes a picture of the sample to be tested, the image taken when the sample is rotated one circle is synchronously transmitted to the industrial computer through the sub-control system of the perforation detection module 6000. After the industrial computer processes the image through image stitching, algorithm recognition, etc., the corresponding perforation parameters are displayed on the display 1100, namely, the hole end distance (the distance from the perforation center to the end face of the filter), hole area, hole diameter, hole roundness, hole spacing (the distance between two adjacent perforation centers), hole circumference, etc.

[0214] The overall control system stores the number and the data of measured physical quantities such as the measured weight, circumference, length, suction resistance, and hole end distance, hole area, hole diameter, hole roundness, hole spacing, and hole circumference and displays them on the display 1100.

After the data is processed, the corresponding weight value is displayed on the display 1100, and the sample to be tested falls to the circumference and length detection module 4000;

At the same time, the solenoid valve MV7 is opened, and the front end of the needle cylinder 5700 pops out.

[0221] ② After the sample to be tested enters the suction resistance detection module 5000, it stays at the front end of the needle cylinder 5700. The latex tubes on the middle clamp block 5420 and the lower clamp block 5320 are wrapped around the surface of the sample to be tested. The CFO in the pipeline forms a stable airflow of 17.5 mL / s under the action of the negative pressure generator, and the solenoid valve MV2 opens.

[0222] ③ The solenoid valve MV6 opens, and the telescopic cylinder 5620 works, driving the probe sealing block 5610 to move, so that the lower part of the probe cavity is sealed. When detecting the open suction resistance, the solenoid valve MV3 opens, and the solenoid valve MV8 closes, allowing air to flow in from the side of the sample and the end face of the tobacco; when detecting the side closed suction resistance, the solenoid valve MV3 and the solenoid valve MV8 are closed, allowing air to flow in from the end face of the sample tobacco; when detecting the end face closed suction resistance, the solenoid valve MV3 is closed, and the solenoid valve MV8 is opened, allowing air to flow in from the side of the sample.
