Description
Technical Field
[0001] The utility model relates to the technical field of cigarette detection, in particular to a cigarette bursting bead detection device. Background Art
[0002] Traditional cigarette filter detection relies primarily on visual inspection and penetrating imaging using high-brightness light sources. However, this method cannot penetrate metal and thicker materials such as paper wrapping, making it impossible to identify most types of cigarette filter beads. TEWS's microwave resonant cavity detection method, which uses a reflective resonant cavity, can only detect non-metallic cigarette filters. In recent years, terahertz technology has also been used for filter detection. Despite its strong penetrating power, terahertz technology is expensive, and the equipment is complex and bulky, making it unsuitable for online testing and unable to penetrate metal materials.

[0029] The specific implementation of the present utility model is described in detail below with reference to the accompanying drawings.
[0030] like Figure 1-4 As shown, a cigarette popping bead detection device includes:
[0031] Servo motor 2;
[0032] Reducer 1; the power output end of the servo motor 2 is connected to the input end of the reducer 1;
[0033] Vacuum pump 3;
[0034] Drum assembly 8; the drum assembly 8 includes a fixed flange seat 82, a transmission shaft 81, a drum 83 and two rollers 84. The fixed flange seat 82 is set in a fixed position, the drum 83 is formed into a cylindrical structure with a hollow interior, and the roller 84 is formed into a circular cylindrical structure protruding outward on the side wall of the drum 83, and the interior of the roller 84 is connected to the interior of the drum 83. Two circles of negative pressure holes 85 parallel to each other are provided on the outer wall of the roller 84. The two circles of negative pressure holes 85 are evenly arranged around the axis of the roller 84, and the line connecting the two closest negative pressure holes 85 in the two circles of negative pressure holes 85 is parallel to the axis of the roller 84. A cigarette 11 is placed on the two negative pressure holes 85 (one in each of the two circles of negative pressure holes 85) for negative pressure adsorption. In the embodiment of the present invention, a plurality of cigarettes 11 are arranged parallel to each other, and each cigarette 11 is parallel to the axis of the roller 84. The first end of the drum 83 is open, and the first end of the drum 83 is rotationally sealed (rotational sealing is a prior art and will not be described in detail here) and is sleeved on the second end of the fixed flange seat 82. The output end of the reducer 1 is connected to the first end of the transmission shaft 81, and the transmission shaft 81 axially passes through the fixed flange seat 82, and its second end is fixedly connected to the inner side of the first end of the drum 83. The fixed flange seat 82 is formed into a cylindrical structure with a hollow interior. The transmission shaft 81 is rotationally sealed with the first end of the fixed flange seat 82. A connecting hole is provided on the side wall of the fixed flange seat 82, and the exhaust end of the vacuum pump 3 is connected to the connecting hole through the air pipe 4.
[0035] Two detection components 9; the two detection components 9 are respectively used to detect the cigarettes 11 on the two rollers 84, and the detection components 9 include a bursting bead detection device 92, and the bursting bead detection device 92 includes a bursting bead detection processor, a bursting bead detection receiving antenna 927, and a bursting bead detection transmitting antenna 928. The bursting bead detection processor is connected to the bursting bead detection receiving antenna 927 and the bursting bead detection transmitting antenna 928 respectively. The bursting bead detection receiving antenna 927 and the bursting bead detection transmitting antenna 928 are respectively installed on the outside of the two end edges of the roller 84, and the bursting bead detection receiving antenna 927 and the bursting bead detection transmitting antenna 928 are arranged opposite to each other, and the microwave path 14 for bursting bead detection passes through the axial direction of the cigarette 11.
[0036] In some embodiments, the burst bead detection device 92 further includes a pushing mechanism. One of the burst bead detection receiving antenna 927 and the burst bead detection transmitting antenna 928 is fixed in one position, and the other is connected to the pushing end of the pushing mechanism. The pushing direction of the pushing mechanism is parallel to the axis of the roller 84. The pushing mechanism here can be selected from a pneumatic cylinder, an electric cylinder, an oil cylinder, etc. The working principle of the burst bead detection device 92 is as follows: the series-fed microstrip antenna operates at a specific microwave frequency, resonating with the water molecules in the burst bead. The cigarette to be detected is axially placed between the burst bead detection receiving antenna 927 and the burst bead detection transmitting antenna 928. The microwave signal generated by the microstrip antenna can then penetrate the cigarette axially. The microwave signal is transmitted by the burst bead detection transmitting antenna 928, while the reflected or transmitted signal is received by the burst bead detection receiving antenna 927. The burst bead detection processor pre-processes the received signal, including filtering and amplification. The signal processing algorithm is used to analyze the change in the scattering parameter of the signal. Based on the change in the scattering parameter, the moisture content of the burst bead is calculated, thereby detecting damage and leakage of the burst bead.
[0037] In some embodiments, as Figure 5-7As shown, the burst bead detection device 92 also includes a mounting frame 921, a mounting slot 922 is provided in the mounting frame 921, and a pushing mechanism includes a stepping motor 923, a screw 925, a slider 926, and two slide rods 924. The two slide rods 924 are mounted on the first end of the mounting frame 921, and two sliding holes and a screw hole are provided in the slider 926 that are parallel to each other. The stepping motor 923 is mounted in the mounting slot 922, and the screw 925 is arranged through the through hole on the first end of the mounting frame 921. The first end of the screw 925 is connected to the rotating shaft of the stepping motor 923, and the screw 925 is threadedly engaged with the screw hole in the slider 926. The slide rod 924 is limitedly slidably engaged with the sliding hole in the slider 926. The burst bead detection receiving antenna 927 is fixedly mounted on the bottom of the second end of the mounting frame 921, and the burst bead detection transmitting antenna 928 is fixedly mounted on the bottom of the slider 926. In this embodiment, the distance between the popping bead detection receiving antenna 927 and the popping bead detection transmitting antenna 928 can be adjusted by a push mechanism, thereby adapting to cigarettes 11 of various lengths. The operating principle of the push mechanism is as follows: the stepper motor 923 rotates, driving the screw 925 to rotate. Because the screw 925 is threadedly engaged with the screw hole in the slider 926, and the two slide holes cooperate with the two slide rods 924, which prevent and guide the slider 926, the slider 926 can only slide back and forth along the slide rods 924. As a result, the popping bead detection transmitting antenna 928 moves away from or closer to the popping bead detection receiving antenna 927, thereby adjusting the distance between the popping bead detection transmitting antenna 928 and the popping bead detection receiving antenna 927.
[0038] In some embodiments, as Figure 5-7 As shown, the detection component 9 also includes a tobacco moisture detection device 91, which includes a tobacco moisture detector 912. The active end of the tobacco moisture detector 912 is positioned near the sidewall of the roller 84 and near the tobacco section of the cigarette 11. The tobacco moisture detection device 91 can be a coaxial sensor such as that described in Patent Publication No. EP2796061A1, "Device and Method for Measuring Capsules in Cigarette Filters." The operating principle of the tobacco moisture detection device 91 is as follows: a microwave resonant cavity operates at a specific microwave frequency, resonating with water molecules. The cigarette to be tested is placed within the resonant cavity's detection range, allowing the microwave signal to penetrate the cigarette. An excitation source transmits a microwave signal with a specific power value, while simultaneously receiving the signal reflected or transmitted by the cigarette. A signal processing algorithm analyzes changes in the signal's scattering parameters. Finally, the current tobacco moisture value is calculated based on the difference between the transmitted and received powers.
[0039] In some embodiments, as Figure 5-7As shown, the tobacco moisture detection device 91 also includes a lifting cylinder 911, which is mounted on a mounting frame 921. The active end of the lifting cylinder 911 is connected to the side wall of the tobacco moisture detector 912 via a connector, and the lower active end of the tobacco moisture detector 912 is installed through a mounting slot 922. In this embodiment, the lifting cylinder 911 drives the tobacco moisture detector 912 up and down, thereby adjusting the distance between its active end and the cigarette 11, thereby adapting the tobacco moisture detection of cigarettes 11 with different diameters.
[0040] In some embodiments, as Figure 1-2 As shown, the online detection device for cigarette popping beads 12 also includes a base 5, a support plate 7, and a connecting seat 10. The support plate 7, the servo motor 2, and the vacuum pump 3 are all mounted on the base 5. The first end of the connecting seat 10 is mounted on one side of the upper end of the support plate 7, and the second end of the mounting frame 921 is mounted on the second end of the connecting seat 10. A mounting hole is provided on the support plate 7, and the fixing flange seat 82 passes through the mounting hole and is mounted on the support plate 7.
[0041] In some embodiments, as Figure 1-2 As shown, the online detection device for cigarette popping beads 12 also includes four ribs 6, which are arranged at the corners where the base 5 and support plate 7 meet. The lower ends of the ribs 6 are connected to the base 5, and one side of the ribs 6 is connected to the side wall of the support plate 7. Two of the ribs 6 are located on the first side wall of the support plate 7, and the other two are located on the second side wall of the support plate 7. The top of the support plate 7 bears a lot of weight, so it may wobble or collapse. Therefore, the purpose of the ribs 6 is to improve the stability of the support plate 7 and provide better support for the support plate 7.
[0042] Working principle:
[0043] The servo motor 2 works, and transmits torque to the transmission shaft 81 through the reducer 1. The transmission shaft 81 rotates to drive the drum 83, and the two rollers 84 also rotate. The multiple cigarettes 11 adsorbed on the rollers 84 also rotate. During the rotation, the popping beads 12 and the tobacco are detected by the popping bead detection device 92 and the tobacco moisture detection device 91 respectively. Figure 7As shown, the microwave path 13 for tobacco moisture detection and the microwave path 14 for popping bead detection are shown; before the servo motor 2 rotates, the vacuum pump 3 sucks the gas in the fixed flange seat 82 through the air pipe 4. Because the fixed flange seat 82, the drum wheel 83, and the two rollers 84 are connected and the interior is closed, the adsorption force acts on the multiple negative pressure holes 85. When loading, the cigarette 11 can be adsorbed on the negative pressure holes 85. In addition, before the servo motor 2 rotates, the distance between the popping bead detection transmitting antenna 928 and the popping bead detection receiving antenna 927 is first adjusted by the pushing mechanism to adapt to the length of the cigarette 11 to be tested; then, the tobacco moisture detector 912 is driven up and down by the lifting electric cylinder 911, and the distance between its active end and the cigarette 11 can be adjusted. After adjustment, it can be achieved to adapt to tobacco moisture detection of cigarettes 11 with different diameters.
[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
