Description

Technical Field

[0001] The invention relates to a rotary disc type continuous cigarette draw resistance detector, belonging to the technical field of cigarette equipment. Background Art

[0002] Cigarette draw resistance is the resistance when smoking a cigarette. It is expressed by the static pressure difference at both ends of the cigarette when a certain flow of air passes through the cigarette under a certain atmospheric environment. Draw resistance actually reflects the smoothness of airflow during the smoking process of the cigarette. Its stability is not only related to the overall quality of the cigarette, but also directly affects the consumer's product recognition. It is also a must-check item for cigarette quality supervision during the cigarette production process. Its test method is mainly carried out in accordance with the national standard GB / T22838-2009 "Determination of Physical Properties of Cigarettes and Filter Rods". According to the national standard method, it usually takes 4s to 6s to test each cigarette, and it usually takes more than three minutes to test a group of 30 cigarettes. If the draw resistance test and other physical test indicators (such as circumference, length and hardness) are measured in combination, the measurement time for each group of cigarettes (30 cigarettes) will be more than 25 minutes, and the efficiency of indicator monitoring in the actual production process is slow. Secondly, in the conventional commercially available draw resistance testing equipment, the draw resistance testing device only measures the two ends of the entire cigarette package. The main disadvantage of this method is that it ignores the air permeability of the cigarette paper on the cigarette support surface, and its measurement results cannot truly reflect the actual quality situation.

[0020] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0021] Embodiments of the present invention: Figure 1-Figure 5As shown, a turntable type continuous cigarette draw resistance detector comprises a smoke supply device 1 and a cigarette detection device 2. The smoke supply device 1 is arranged above the cigarette detection device 2. The smoke supply device 1 can be fixed by a metal bracket (the bracket can be an ordinary bracket, so it is not shown in the figure). The smoke supply device 1 has a smoke outlet 3. The cigarette detection device 2 comprises a circular disk body 4, a clamping device 5 and a gas pressure sensor 6. The rotating shaft 28 of the circular disk body 4 is a hollow structure. The circular disk body 4 is supported by a bracket 30 and can rotate on the bracket under the drive of a driving device 31. The driving device 31 can adopt a servo motor. A plurality of radially arranged accommodating holes 7 are formed on the circular disk body 4. The number of the accommodating holes 7 can be set to 20-30, and each accommodating hole 7 can be set to 20-30. The diameters of the cigarettes are equal and larger than the outer diameter of the cigarettes, so that after the cigarettes enter the receiving holes 7, the side walls of the cigarettes can fully contact with the air to ensure the accuracy of the measuring structure. A clamping device 5 is arranged in each receiving hole 7, and each clamping device 5 is connected to a gas pressure sensor 6, and each gas pressure sensor 6 is connected to a control valve 8. The clamping device 5 is connected to the gas pressure sensor 6 through the first connecting air pipe 29, and is connected to the control valve 8 through the second connecting air pipe. The opening and closing states of the clamping device 5 can be controlled by the control valve 8 and the second connecting air pipe. The gas pressure sensor 6 is connected to the control valve 8 through the third connecting air pipe, and the control valve 8 is connected to the rotating shaft 28 through the fourth connecting air pipe, and the rotating shaft 28 is connected to the air extraction device.

[0022] During operation, driven by the servo motor, the circular disk 4 rotates slowly on the bracket. When the receiving hole 7 on the circular disk 4 rotates to the 12 o'clock position, the receiving hole 7 is in a vertical direction and is directly opposite to the smoke outlet 3 on the smoke supply device 1. At this time, the smoke supply device 1 works and delivers a cigarette through the smoke outlet 3. The cigarette mouth end faces downward. After passing through the smoke outlet 3, the cigarette falls into the receiving hole 7. The clamping device 5 in the receiving hole 7 is in an open state. When the cigarette falls freely to the position of the clamping device 5, the clamping device 5 closes and clamps the cigarette. The opening and closing state of the clamping device 5 is achieved by the control valve 8. The exhaust device continuously exhausts the rotating shaft 28 to form a negative pressure in the rotating shaft 28. When the control valve 8 connects the fourth connecting air pipe with the second connecting air pipe, the clamping device 5 opens. When the control valve 8 disconnects the two, the clamping device 5 automatically closes. When the cigarette is clamped, the control valve 8 controls the fourth connecting air pipe to be connected to the third connecting air pipe, providing a quantitative air pressure of 17.5 ml / s to the gas pressure sensor 6. The end of the gas pressure sensor 6 connected to the clamping device 5 draws the cigarette and measures the gas pressure at this end, thereby obtaining the size of the draw resistance. When the cigarette with measured draw resistance is turned to the 6 o'clock direction, the clamping device 5 automatically opens under the action of the control valve 8, and the cigarette automatically leaves the receiving hole 7 under the action of gravity. In order to improve work efficiency, a cigarette recovery box 27 can be placed directly below the cigarette detection device 2.

[0023] In a specific embodiment, the smoke supply device 1 includes a motor 9, a screw 10, a support block 11, a guide rod 12, a smoke box 13 and a push roller 14. Guide holes are formed on the top and bottom of the smoke box 13. The push roller 14 is accommodated in the smoke box 13, and connecting rods 15 at both ends of the push roller 14 extend out of the smoke box 13 through the guide holes. The screw 10 and the guide rod 12 are respectively arranged above and below the smoke box 13. A first slider 16 threadedly connected to the screw 10 is provided on the connecting rod 15 at one end of the push roller 14, and a second slider 17 slidingly matched with the guide rod 12 is provided on the connecting rod 15 at the other end. The motor 9 is connected to one end of the screw 10, and the other end of the screw 10 is rotatably connected to the support block 11. One end of the smoke box 13 has a smoke outlet 3.

[0024] Figure 4 The structure shown is two sets of cigarette supply devices 1. In order to improve the efficiency of cigarette supply, two sets of devices can be set to share cigarettes at the same time. When working, the motor 9 drives the screw 10 to rotate, and the screw 10 drives the first slider 16 matched with its thread to move. The first slider 16 drives the push roller 14 to move left and right in the cigarette box 13. The cigarette box 13 is a rectangular parallelepiped structure, and its internal width is slightly larger than the diameter of a cigarette. The cigarette box 13 can usually accommodate 30 cigarettes. The push roller 14 moves the distance of a cigarette each time, so as to push a cigarette to the cigarette outlet 3 and let it fall. In order to prevent the cigarette from tipping over and tilting sideways, a downwardly folded spring baffle 32 can be set at the top of the end of the cigarette box 13 with the cigarette outlet 3. The advantage of setting two sets of cigarette supply devices 1 is that when one of them is loading cigarettes, the other one continues to work, so as to achieve uninterrupted and non-stop testing.

[0025] It should be noted that the clamping device 5, the gas pressure sensor 6 and the control valve 8 can be controlled manually or automatically. In a preferred embodiment, a laser sensor 18 and a light emitting device 26 are also included, and the laser sensor 18 is arranged below the smoke outlet 3.

[0026] The clamping device 5 includes a cylindrical barrel 19 and an annular latex sleeve 20. A mounting boss 21 is formed on the inner wall surface of the upper end of the cylindrical barrel 19. The annular latex sleeve 20 is sleeved on the mounting boss 21. The mounting boss 21 is provided with an air source interface 22, which is connected to the second connecting air pipe. The lower end of the cylindrical barrel 19 is provided with a connector 23 connected to the inside thereof, which is connected to the first connecting air pipe. In order to prevent the annular latex sleeve 20 from loosening, a card groove 24 facing the inner wall direction of the receiving hole 7 can be formed on the outer wall of the mounting boss 21.

[0027] Furthermore, the cigarette detection device 2 further includes a plurality of photoelectric switches 25, which are arranged on the outer wall surface of the circular disk 4, and each photoelectric switch 25 is connected to a control valve 8; and further includes a light emitting device 26, which divides the circular disk 4 into a left half and a right half by a vertical line passing through the center of the circular disk 4 as a dividing line, and the light emitting device 26 is used to illuminate the left half or the right half. The light emitting device 26 includes a light box and an LED lamp.

[0028] Taking the case where the light emitting device 26 illuminates the left half of the circular disk 4 and the circular turntable 4 rotates clockwise as an example, as the circular disk 4 rotates, the photoelectric switch 25 that rotates to the left half will be illuminated by the light emitting device 26, and the photoelectric switch 25 sends a signal to the control valve 8, and the control valve 8 connects the fourth connecting air pipe with the second connecting air pipe. At this time, the gas in the mounting boss 21 and the annular latex sleeve 20 is extracted under the action of negative pressure, and the inner diameter of the annular latex sleeve 20 becomes larger. When the cigarette enters the annular latex sleeve 20, the circular disk 4 continues to rotate clockwise, and the cigarette receiving hole 7 and the corresponding The photoelectric switch 25 rotates out of the irradiation area of ​​the light emitting device 26, and the photoelectric switch 25 sends a signal to the control valve 8. The control valve 8 connects the fourth connecting air pipe with the third connecting air pipe. At this time, the air pressure in the annular latex sleeve 20 and the mounting boss 21 returns to normal, the annular latex sleeve 20 automatically recovers and clamps the cigarette. At the same time, negative pressure acts on the gas pressure sensor 6 to perform a suction resistance test on the cigarette. When the circular disk 4 rotates to the 6 o'clock position, the test is completed. At the same time, the photoelectric switch 25 is irradiated by the light emitting device 26 again, the clamping device 5 opens, and the cigarette automatically detaches and falls into the cigarette recovery box 27.
