DETAILED DESCRIPTION

[0027] The specific implementation of the embodiment will be described below in conjunction with the accompanying drawings. Figures 1-3

[0028] The embodiment of the application provides a multi-specification cigarette draw resistance detection and sorting device, which refers to Figure 1 , and comprises:

[0029] The cigarette blanking mechanism 1 is a storage and blanking mechanism for the to-be-detected cigarette 12, can be adapted to various specifications of the cigarette 12, and is internally provided with the second sliding channel 13. The to-be-detected cigarette 12 is sent to the blanking opening in the mode of the cigarette mouth downward and the cigarette head upward along the second sliding channel 13 through roller sorting, and the blanking opening position of the cigarette blanking mechanism 1 corresponds to the clamping hole position of the gripper 2 in the draw resistance detection and calibration mechanism. In the detection process, the to-be-detected cigarettes 12 of the same batch are of the same specification.

[0030] The draw resistance detection and calibration mechanism comprises a plurality of grippers 2, the specifications of the grippers 2 are different, and the grippers 2 are arranged in a straight line and can be adapted to cigarettes 12 of different lengths and different circumferential sizes. Figure 2 ​The holder 2 includes an upper clamping head 2-1, a lower clamping head 2-2, an O-shaped sealing ring 2-3, and a holder base 2-4. The upper clamping head 2-1 is used to clamp the cigarette head portion of the cigarette 12, and the lower clamping head 2-2 is used to clamp the filter tip portion. A latex tube (not shown in the figure) is arranged inside the upper clamping head 2-1 and the lower clamping head 2-2. The upper clamping head 2-1 and the lower clamping head 2-2 are inflated by the positive pressure latex tube to wrap the upper and lower ends of the cigarette, thereby ensuring that the airflow passes through the inside of the cigarette. The upper clamping head 2-1 and the lower clamping head 2-2 are also provided with grooves on the outside, and the O-shaped sealing ring 2-3 is arranged in the grooves to ensure the sealing effect in the middle of the O-shaped sealing ring and avoid air leakage.

[0031] In this embodiment, three holders 2 are arranged, and the lower end of the holder 2 is fixed to the holder base 2-4 through a positioning pin 2-5. The holder base 2-4 is also provided with a hole inside, which is connected to the suction resistance detector 5 through a suction resistance air path joint (not marked in the figure). In addition, a scale is arranged on the surface of the holder 2. When manually adjusting the distance between the latex tubes in the holder 2, the scale can be used to further ensure the accuracy of the adjustment, thereby realizing the adaptation to cigarettes 12 of different lengths.

[0032] The suction resistance detector 5 includes a differential pressure meter, a constant flow hole, a standard rod, a proportional valve, a flow meter, an electromagnetic valve, etc. The airflow is sucked from the cigarette tobacco head to the constant flow hole, and is connected to the differential pressure meter and the negative pressure generator. The upper and lower clamping heads in the holder are wrapped around the upper and lower ends of the cigarette by the inflation of the positive pressure latex tube, thereby ensuring that the airflow passes through the inside of the cigarette. The constant flow hole generates a standard constant airflow (17.5 ml / s), and the differential pressure meter calculates the suction resistance value through the airflow pressure and atmospheric pressure difference. The negative pressure generator generates a negative pressure to simulate the action of human mouth suction. In this embodiment, the suction resistance detector is an existing device, and its detection principle will not be described in detail. The suction resistance detector 5 can accurately detect the suction resistance and ventilation degree values of the cigarette. The suction resistance detector 5 also includes a standard rod, a proportional valve, and a flow meter. The standard rod can be used to periodically calibrate the suction resistance and ventilation degree values inside the suction resistance detector 5, and the proportional valve and the flow meter can be used to detect whether the latex tube is damaged and leaks.

[0033] The holder 2 is also fixed with a linear guide rail 3 and a servo motor 4 for controlling the movement of the linear guide rail. The servo motor 4 drives the ball screw to drive multiple holders 2 to move along the linear guide rail 3, thereby enabling the holder 2 matched with the specifications of the cigarette 12 to clamp the cigarette for suction resistance testing.

[0034] The blanking hole below the gripper 2 corresponds to the entrance of the first slide 6, which is also an arc-shaped slide, and the lower end of the first slide 6 is fixed with a conveying belt 7 of a cigarette sorting mechanism. The cigarette 12 after the detection of the suction resistance is conveyed to the cigarette sorting mechanism through the first slide 6. The lower end of the first slide 6 is also provided with a first photoelectric sensor 9 for detecting whether the cigarette enters the conveying belt 7. A plurality of push rods 8 are also fixed on both sides of the conveying belt 7, and the push rods 8 are pushed by a cylinder, and the cigarettes are pushed into the cigarette blanking bin 10 below the push rod by the push rod 8. In this embodiment, a second photoelectric sensor 14 is arranged on each push rod, which can detect which bin the cigarette 12 falls into through the second photoelectric sensor 14, and then automatically realize the classification and detection of different specifications of cigarettes. In the device mentioned in this embodiment, an electrical component board 11 is also included, which is used to install a power supply and a communication module.

[0035] In addition, as shown in Figure 3 The rotary slide 15 driven by the servo motor can be used to control the rotary movement of the gripper 2, and the rotary slide 15 is rotated by the rotary screw driven by the servo motor, so that the gripper 2 matched with the specification of the cigarette 12 is switched to the corresponding station; in the process of using the rotary slide 15 driven by the servo motor to control the gripper 2, the grippers 2 are arranged in a circle.

[0036] The working principle of the multi-specification cigarette suction resistance detection and sorting device provided in this embodiment is as follows:

[0037] The to-be-detected cigarette 12 is sorted by the rollers in the cigarette blanking mechanism 1 to the second slide 13, and is slid into the clamping hole of the gripper 2 in the posture of the cigarette with the mouthpiece downward and the cigarette tip upward. The plurality of grippers 2 are moved along the linear guide rail 3 by the servo motor 4 rotating the ball screw, so that the gripper 2 matched with the specification of the cigarette 12 clamps the to-be-detected cigarette. The position of the latex tube is adjusted by the adjusting knob above the gripper 3, so that the latex tube wraps the upper and lower ends of the cigarette 12. The latex tube is connected with the suction resistance detector 5 through the suction resistance gas connection on the gripper base 2-4. The airflow in the suction resistance detector 5 is sucked from the cigarette tip part to the constant-flow hole, passes through the differential pressure meter and the negative pressure generator, and then the suction resistance performance test of the cigarette is completed. The cigarette 12 after the test is conveyed to the cigarette sorting mechanism through the first slide 6, and the push rod 8 is driven by the cylinder to automatically push the cigarettes 12 of different specifications into the cigarette classification blanking bin 10.

[0038] Although the specific embodiments of the utility model have been described in combination with the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
