Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cigarette product quality detection, and particularly relates to an energy-saving cigarette head drop detection device. BACKGROUND

[0002] Cigarette head drop is a physical quality defect of cigarettes, which refers to the phenomenon that the burning cone of a cigarette falls off due to the impact behavior of a consumer during smoking, which seriously affects the sensory quality of the cigarette and damages the interests of the consumer.

[0003] The main reasons for the cigarette burning cone drop are usually as follows: 1. Changes in the properties of cigarette paper (combustion improver content, air permeability) cause differences between the combustion of cigarette paper and the combustion of tobacco in a cigarette, which changes the ash removal performance of the cigarette and the volume (weight) of the burning cone, and when the ash is knocked off, the burning cone is easily separated from the main body of the cigarette due to the change in the stress state; 2. The addition of expanded tobacco and cut tobacco in the formula changes the filling property of the tobacco, which easily causes local structural looseness during combustion, thereby causing the occurrence of the cigarette drop phenomenon during combustion; 3. When the cigarette rolling quality is poor, the tobacco in the cigarette is unevenly distributed in the axial direction, and under the action of a certain external force, the burning cone is easily separated.

DETAILED DESCRIPTION

[0026] In order to make the skilled in the art better understand the present application, the technical solutions of the present application are further described below in combination with the drawings and examples.

[0027] As Figures 1-6 shown, the energy-saving cigarette head falling detection device of the present application comprises a base 8 and a telescopic motor 1, a suction device 2, a fixing device 3 installed on the base 8 in sequence, and a knocking device 4 installed on the fixing device 3.

[0028] The suction device 2 comprises a stepped sleeve 21 and a piston slidingly arranged in the stepped sleeve 21, the piston is divided into a first piston 22 and a second piston 23, a compression cavity 25 is formed between the first piston 22 and the second piston 23, a first spring 24 is fixedly connected between the first piston 22 and the second piston 23, a first sliding cavity 211 and a second sliding cavity 212 are arranged in the stepped sleeve 21, the first piston 22 is slidingly arranged in the first sliding cavity 211, the second piston 23 is slidingly arranged in the second sliding cavity 212, a connecting frame 221 is fixedly connected to one side of the first piston 22, and the connecting frame 221 is fixedly connected to the telescopic shaft 11 of the telescopic motor 1. A limiting ring 213 is integrally formed in the second sliding cavity 212 at one end of the first sliding cavity 211, and the first spring 24 is a rigid spring.

[0029] The fixing device 3 comprises a fixed plate 31, one side of the fixed plate 31 is integrally formed with a fixed cylinder 32, the fixed cylinder 32 is fixedly connected to one end of the stepped sleeve 21, so that the stepped sleeve 21 is in communication with the fixed cylinder 32. A connecting cylinder 5 is threadedly connected in the fixed cylinder 32, the connecting cylinder 5 is provided with a fixed sleeve 52 at one end, the fixed sleeve 52 is made of elastic material, and the filter end of the to-be-detected cigarette 7 is inserted into the fixed sleeve 52.

[0030] When the telescopic motor 1 works, the telescopic shaft 11 of the telescopic motor 1 is retracted, the first piston 22 is driven to slide in the first sliding cavity 211, the second piston 23 is driven to slide in the second sliding cavity 212, and the cigarette 7 is sucked. When the second piston 23 moves to the limiting ring 213, the second piston 23 stops moving, and the cigarette 7 suction operation is completed.

[0031] The stepped sleeve 21 is provided with a first mounting hole at the end of the first sliding cavity 211, a second hose 44 is mounted in the first mounting hole, the knocking device 4 comprises a gas cylinder 41, the gas cylinder 41 is provided with a gas passage at the top end, one end of the second hose 44 is sealingly connected in the first mounting hole, and the other end is sealingly connected in the gas passage, so that the gas cylinder 41 is in communication with the compression cavity 25. The fixed plate 31 is provided with a mounting frame 33, and the gas cylinder 41 is fixedly mounted in the mounting frame 33.

[0032] The third piston 42 is slidingly arranged in the gas cylinder 41, the lower surface of the third piston 42 is integrally formed with a sliding column 43, the bottom end of the gas cylinder 41 is provided with a fifth through hole, the sliding column 43 is sealingly arranged in the fifth through hole, the end of the sliding column 43 is fixedly provided with a knocking head 431, and the knocking head 431 is located on the upper end of the cigarette 7. The second spring 45 is sleeved on the sliding column 43, one end of the second spring 45 is fixedly connected with the knocking head 431, and the other end is fixedly connected to the bottom end of the gas cylinder 41.

[0033] Because the diameter of the first piston 22 is larger than that of the second piston 23, when the cigarette 7 is inhaled, the compression chamber 25 is in a negative pressure state. Gas in the gas cylinder 41 is extracted through the second hose 44, causing the third piston 42 to rise, driving the sliding column 43 and the striking head 431 to rise, and compressing the second spring 45.

[0034] The first piston 22 is integrally formed with a plurality of slide rods 222. A blind hole 223 is defined at one end of the slide rod 222, extending through the first piston 22. A notch 224 is defined at the blind hole 223 of the slide rod 222. A limit cylinder 214 is disposed within the first sliding cavity 211. A limit plate 215 is integrally formed at the end of the limit cylinder 214. The limit plate 215 is provided with a plurality of fourth through holes, through which the slide rods 222 are inserted. Sealing rings are provided at the fourth through holes, ensuring a sealed connection between the slide rods 222 and the fourth through holes.

[0035] When the cigarette 7 is puffed, the telescopic shaft 11 continues to contract, and the first spring 24 stretches, allowing the first piston 22 to continue moving. After the first piston 22 contacts the limit plate 215, the telescopic shaft 11 stops moving. At this time, the blind hole 223 is located within the fourth through hole, and the compression chamber 25 is connected to the outside world through the blind hole 223. The air pressure in the compression chamber 25 is balanced. The compressed second spring 45 rebounds, causing the knocking head 431 to spring downward, knocking the cigarette 7.

[0036] An adjustment tube 26 is provided on the outer surface of the stepped sleeve 21. A first protruding ring 216 is integrally formed at the end of the stepped sleeve 21 on the side of the stop tube 214. A fixing ring 27 is fixedly connected to one end of the stepped sleeve 21. A second protruding ring 261 is integrally formed on the inner side of the adjustment tube 26. The second protruding ring 261 is rotatably mounted between the first protruding ring 216 and the fixing ring 27, thereby rotatably connecting the adjustment tube 26 to the stepped sleeve 21. An adjustment platform 217 is integrally formed at the end of the stop tube 214. The adjustment platform 217 has an external thread, and the adjustment tube 26 has an internal thread. The external and internal threads threadably connect the adjustment tube 26 to the adjustment platform 217. By rotating the adjustment tube 26, the position of the stop tube 214 can be adjusted, thereby changing the maximum position of the first piston 22, thereby adjusting the maximum position of the third piston 42, and changing the compression degree of the second spring 45 to achieve the purpose of adjusting different striking forces.

[0037] The other end of the connecting cylinder 5 is provided with a first through hole 51, and a first one-way valve 61 is fixedly installed in the first through hole 51. The second piston 23 is provided with a second through hole 231 on the side of the connecting cylinder 5, and a second one-way valve 62 is fixedly installed in the second through hole 231. The stepped sleeve 21 is provided with a second installation hole on the side of the first installation hole, and a third one-way valve 63 is installed in the second installation hole. A gas collecting box 81 is fixedly installed on the base 8. The second piston 23 is fixedly connected with an air pipe 232 at the second through hole 231. The first piston 22 is provided with a third through hole, and one end of the air pipe 232 penetrates through the third through hole. One end of the air pipe 232 is sealingly connected with a first hose 233, and the first hose 233 penetrates out of the connecting frame 221 and communicates with the gas collecting box 81. A filtering device 82 is installed on the gas collecting box 81 to filter the smoke in the gas collecting box 81.

[0038] When the cigarette 7 is smoked, the first one-way valve 61 is opened, and the second one-way valve 62 and the third one-way valve 63 are closed. When the telescopic shaft 11 of the telescopic motor 1 is elongated, the first piston 22 and the second piston 23 move towards the cigarette 7, the first one-way valve 61 is closed, and the second one-way valve 62 and the third one-way valve 63 are opened. The gas in the compression cavity 25 is discharged to the outside through the third one-way valve 63. The smoke between the first one-way valve 61 and the second one-way valve 62 enters the air pipe 232 through the second one-way valve 62, and then enters the gas collecting box 81 through the first hose 233. The filtering device 82 filters the smoke and then discharges it.

[0039] One end of the stepped sleeve 21 is provided with a first connecting ring 218, and the end of the fixed cylinder 32 is provided with a second connecting ring 321. Connection holes are formed in the first connecting ring 218 and the second connecting ring 321, and bolts penetrate through the connection holes to fixedly connect the first connecting ring 218 and the second connecting ring 321. A sealing groove is formed in the first connecting ring 218, and a sealing ring is embedded in the sealing groove to increase the sealing property of the connection between the first connecting ring 218 and the second connecting ring 321.

[0040] The energy-saving cigarette falling detection device of the application is used to insert the filter end of the cigarette 7 to be detected into the fixed sleeve 52, and the telescopic motor 1 is operated. The telescopic shaft 11 is retracted to drive the first piston 22 to slide in the first sliding cavity 211 and the second piston 23 to slide in the second sliding cavity 212 to smoke the cigarette 7. When the second piston 23 moves to the limiting ring 213, the second piston 23 stops moving, the smoking action of the cigarette 7 is completed, and the third piston 42 rises to drive the sliding column 43 and the knocking head 431 to rise and compress the second spring 45.

[0041] When the cigarette 7 is finished with the smoking action, the telescopic shaft 11 continues to shrink, the first spring 24 is stretched, so that the first piston 22 continues to move, and the second spring 45 is continuously compressed. When the first piston 22 contacts the limiting plate 215, the telescopic shaft 11 stops moving. At this time, the blind hole 223 is located in the fourth through hole, the compression cavity 25 is communicated with the outside through the blind hole 223, and the air pressure in the compression cavity 25 is balanced. The second spring 45 in the compressed state rebounds, so that the knocking head 431 is bounced down, and the cigarette 7 is knocked to complete the knocking action.

[0042] When the cigarette 7 is smoked, the first one-way valve 61 is opened, and the second one-way valve 62 and the third one-way valve 63 are closed. After a test is completed, the telescopic shaft 11 of the telescopic motor 1 is elongated, the first piston 22 and the second piston 23 move to the side of the cigarette 7, the first one-way valve 61 is closed, the second one-way valve 62 and the third one-way valve 63 are opened, and the gas in the compression cavity 25 is discharged to the outside through the third one-way valve 63. The smoke between the first one-way valve 61 and the second one-way valve 62 enters the air pipe 232 through the second one-way valve 62, and then enters the gas collection box 81 through the first hose 233. After being filtered by the filter device 82, the smoke is discharged.

[0043] Compared with the prior art, the same telescopic motor can drive the smoking device 2 to complete the smoking action and drive the knocking device 4 to complete the knocking action, so that the structure is simple and energy is saved.
