[0042] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0043] like Figures 1 to 3 As shown, in this embodiment, the cigarette punching quality detection device includes:

[0044] The dropping mechanism 1 includes a hopper 11, a distributor 12, a rotary drive unit 13, and a dropping channel 14. The distributor 12 is horizontally arranged at the bottom of the hopper 11 and connected to the driving end of the rotary drive unit 13. A cigarette receiving groove 121 extending along its axial direction is provided on the outer surface of the distributor 12. The cigarette receiving groove 121 is used to accommodate cigarettes discharged from the hopper 11. The dropping channel 14 is located below the distributor 12. The cigarettes in the cigarette receiving groove 121 are rotated by the rotary drive unit 13 to drop into the dropping channel 14 one by one. The dropping channel 14 is provided with a guide portion 141 for guiding the cigarettes falling into the dropping channel 14 from horizontal extension to vertical extension.

[0045] The clamping mechanism 2 is provided below the drop channel 14 and is used to clamp the cigarettes dropped from the drop channel 14;

[0046] The rotating mechanism 3 is connected to the clamping mechanism 2 and is used to rotate the clamping mechanism 2 to rotate the cigarette;

[0047] The image acquisition mechanism 4 is provided on one side of the clamping mechanism 2 and is used to acquire an image of the filter of the cigarette.

[0048] With this technical solution, the rotary drive unit 13 drives the divider 12 to rotate, and during the rotation of the divider 12, the cigarettes in the cigarette receiving slot 121 can be dropped one by one onto the guide portion 141 of the drop channel 14. The guide portion 141 changes the cigarette extension from a horizontal state to a vertical state, and the cigarettes extending in the vertical direction fall through the outlet at the bottom of the drop channel 14 to the bottom of the drop mechanism 1. The present application sets a clamping mechanism 2 and a rotating mechanism 3 below the drop mechanism 1. The clamping mechanism 2 clamps the vertical cigarettes, and the rotating mechanism 3 drives the clamping mechanism 2 and the cigarettes to rotate. During the rotation of the cigarettes, the image acquisition mechanism 4 captures the image of the cigarette filter, so that the punching quality of the cigarette filter can be detected based on the acquired image. The cigarette punching quality detection device provided by the utility model can realize automatic detection of cigarette punching quality, replacing manual detection, thereby improving detection efficiency and detection accuracy.

[0049] Specifically, if Figures 1 to 3 As shown, the hopper 11 is used to accommodate multiple cigarettes placed horizontally. The bottom of the hopper 11 is provided with a horizontally extending opening 111. The divider 12 is disposed at the bottom opening 111 of the hopper 11, with part of the divider located inside the hopper 11 through the opening 111 and part of the divider located outside the hopper 11. The divider 12 is rotated at the opening 111 by a rotary drive unit 13. The outer surface of the divider 12 is provided with a cigarette receiving groove 121 extending along its axial direction. The cigarette receiving groove 121 can accommodate a single cigarette. When the rotary drive unit 13 drives the divider 12 to rotate, when the cigarette receiving groove 121 on the divider 12 faces upward from the opening 111, the cigarette falls into the cigarette receiving groove 121. When the cigarette receiving groove 121 on the divider 12 rotates to face downward from the opening 111, the cigarette falls into the drop channel 14. A guide 141 is provided within the drop channel 14, which guides the cigarette from its initial horizontal extension to a vertical extension. More specifically, when a cigarette is placed horizontally within the hopper 11, its filter end faces the drop channel 14. After the cigarette falls from the cigarette receiving slot 121, it slides down through the guide 141, dropping into the drop channel 14 in a vertically extending manner with the filter end at the bottom.

[0050] Further, if Figure 3As shown, the outer surface of the divider 12 is further provided with a plurality of protrusions 122 spaced apart along the axial direction of the divider 12 . The protrusions 122 extend along the circumference of the divider 12 and avoid the cigarette receiving grooves 121 .

[0051] Specifically, in this embodiment, the protrusion 122 is annular and is disposed on the outer surface of the divider 12 along the circumference of the divider 12. The protrusion 122 is provided with a notch that allows the cigarette receiving slot 121 to be avoided, so that cigarettes in the hopper 11 can fall into the cigarette receiving slot 121. Once a cigarette falls into the cigarette receiving slot 121, the protrusion 122 prevents other cigarettes from becoming stuck in the gap between the divider 12 and the opening 111 at the bottom of the hopper 11 during the rotation of the divider 12.

[0052] Optionally, avoidance portions are respectively provided on both sides of the opening 111 at positions corresponding to the protrusions 122 , so that the protrusions 122 can pass through the avoidance portions, thereby preventing the gap between the distributor 12 and the opening 111 from being too large.

[0053] Furthermore, the width of the cigarette receiving slot 121 in the circumferential direction of the distributor 12 is 1.1 to 1.2 times the diameter of the cigarette. Thus, the cigarette receiving slot 121 can only accommodate one cigarette at a time. Each time the distributor 12 rotates once, one cigarette is separated from the hopper 11.

[0054] Optionally, the depth of the cigarette receiving groove 121 is half the diameter of the cigarette, thereby ensuring that the cigarette can fall into the cigarette receiving groove 121.

[0055] Furthermore, the guide portion 141 is in an outwardly protruding arc shape. With this technical solution, the horizontally extending cigarette can be adjusted to a vertically extending state during the free fall process, and it is not easy to cause blockage or jamming.

[0056] Specifically, a channel is formed between the bottom of the guide portion 141 and the inner side wall of the drop channel 14 , which can accommodate a single cigarette. The cigarette moves downward from the channel to the clamping mechanism 2 .

[0057] Furthermore, it also includes a control unit, a first proximity switch and a first trigger member. The first trigger member is arranged at one end of the distributor 12. The first proximity switch is electrically connected to the control unit and is arranged on a side close to the rotation drive unit 13, and is used to send a first trigger signal to the control unit when the first trigger member is detected.

[0058] By adopting this technical solution, the number of rotations of the distributor 12 can be identified and counted.

[0059] Specifically, in this embodiment, a first triggering member is disposed at one end of the divider 12, corresponding to the cigarette receiving slot 121. A first proximity switch is also disposed at a position corresponding to this end of the divider 12, for detecting the first triggering member. The first proximity switch detects the first triggering member once each time the divider 12 rotates. When the first proximity switch detects the first triggering member, it sends a first triggering signal to the control unit. Upon receiving the first triggering signal, the control unit counts the number of rotations of the divider 12, and thereby also counts the number of cigarettes detected.

[0060] Optionally, the first triggering member is a triggering block or a screw.

[0061] Further, if Figure 5 As shown, the clamping mechanism 2 includes:

[0062] A first clamping member 21 and a second clamping member 22, wherein the middle portion of the first clamping member 21 is rotatably connected to one end of the second clamping member 22, and the end portion of the first clamping member 21 and the other end of the second clamping member 22 form a clamping position for clamping a cigarette in a vertical state;

[0063] an elastic member 23, one end of the elastic member 23 being connected to the first clamping member 21, and the other end being connected to the second clamping member 22, the elastic member 23 being used to provide a force for the first clamping member 21 and the second clamping member 22 to move closer to each other;

[0064] a first drive unit 24;

[0065] The blocking rod 25 has one end connected to the driving end of the first driving unit 24 to drive the blocking rod 25 to extend or retract; when the blocking rod 25 is extended, the other end of the blocking rod 25 abuts against the outer side of the end of the first clamping member 21 away from the clamping position to apply a force to the first clamping member 21, so that the first clamping member 21 and the second clamping member 22 are opened; when the blocking rod 25 is retracted, the blocking rod 25 is separated from the first clamping member 21, and the first clamping member 21 and the second clamping member 22 rotate towards each other under the action of the elastic member 23 to provide a clamping force on the cigarette.

[0066] Specifically, the first clamping member 21 and the second clamping member 22 are two clamping arms. A plurality of first teeth are provided in the middle of the first clamping member 21, and a first concave groove is provided on one end of the first clamping member 21 for engaging with the second clamping member 22. A plurality of second teeth are provided on one end of the second clamping member 22 to engage with the first teeth, allowing the first and second clamping members 21 and 22 to rotate relative to each other. A second concave groove is provided on the other end of the second clamping member 22. When the first and second clamping members 21 and 22 are in the clamping position, the first concave groove and the second concave groove are connected and can accommodate a single cigarette. The first and second clamping members 21 and 22 exert a clamping force on the cigarette, holding it in a vertical position.

[0067] The first clamping member 21 and the second clamping member 22 are connected by an elastic member 23 to provide a force for the clamping ends of the first clamping member 21 and the second clamping member 22 to move closer to each other.

[0068] The blocking rod 25 is horizontally disposed on one side of the first clamping member 21 . One end of the blocking rod 25 is connected to the driving end of the first driving unit 24 . The blocking rod 25 is driven to extend or retract by the first driving unit 24 .

[0069] Optionally, the first drive unit 24 is an electromagnet. When the electromagnet is energized, it drives the blocking rod 25 to retract toward the electromagnet, and the first and second clamping members 21, 22 clamp the cigarette together under the tension of the elastic member 23. When the electromagnet is de-energized, the blocking rod 25 pops out away from the electromagnet. When the distal end of the blocking rod 25 abuts the end of the first clamping member 21, the blocking rod 25 applies a force to the first clamping member 21, causing the clamping ends of the first clamping member 21 and the second clamping member 22 to open relative to each other.

[0070] Furthermore, it also includes a second proximity switch and a second trigger member, the second trigger member is arranged at one end of the first clamping member 21 or one end of the second clamping member 22, the second proximity switch is electrically connected to the control unit and is arranged on a side close to the first driving unit 24, and is used to send a second trigger signal to the control unit when the second trigger member is detected.

[0071] Specifically, a second trigger is disposed on one end of the first clamping member 21 near the barrier rod 25 or on the other end of the second clamping member 22 near the barrier rod 25. A second proximity switch is provided on one side of the first drive unit 24 to detect the second trigger. When the second proximity switch detects the second trigger, it indicates that the clamping mechanism 2 has completed one rotation. The control unit then controls the first drive unit 24 to extend the barrier rod 25, releasing the clamped cigarette. In this embodiment, the second trigger is disposed on one end of the first clamping member 21. Alternatively, the second trigger is a trigger block or a screw.

[0072] Further, if Figure 4 and Figure 5 As shown, the rotating mechanism 3 includes:

[0073] A second driving unit 31;

[0074] The connecting turntable 32 has a through hole in the middle thereof for cigarettes to pass through. The second driving unit 31 is directly or indirectly connected to the connecting turntable 32 to drive the connecting turntable 32 to rotate. The first clamping member 21 and the second clamping member 22 are rotatably arranged below the connecting turntable 32.

[0075] Specifically, in this embodiment, a connecting turntable 32 is positioned between the drop channel 14 and the clamping mechanism 2. A through hole for cigarettes to pass through is located in the middle of the connecting turntable 32, directly below the opening at the lower end of the drop channel 14. Cigarettes falling from the drop channel 14 pass through the through hole of the connecting turntable 32 and land on the clamping mechanism 2. A driving pulley 34 is positioned adjacent to the connecting turntable 32, connected to the driving pulley 34 by a timing belt 33. The driving end of the second drive unit 31 is connected to the driving pulley 34. The second drive unit 31 drives the driving pulley 34 to rotate, thereby driving the connecting turntable 32 via the timing belt 33. The first and second clamping members 21 and 22 are rotatably fixed below the connecting turntable 32. Rotation of the connecting turntable 32 drives the first and second clamping members 21 and 22, thereby rotating the clamped cigarettes about their vertical axes.

[0076] In order to ensure that the cigarette is smoothly clamped in a vertical state by the first clamping member 21 and the second clamping member 22, the center of the channel opening at the lower end of the blanking channel 14, the center of the through hole connecting the turntable 32, and the center of the first concave groove and the hole formed by the second concave groove when the first clamping member 21 and the second clamping member 22 are in the clamping position are on the same vertical line.

[0077] Exemplarily, the rotating mechanism 3 further includes an adjusting wheel 35 , which is arranged to connect the turntable 32 and the driving wheel 34 and is located outside the synchronous belt 33 , and is used to tension the synchronous belt 33 .

[0078] Furthermore, in this embodiment, an encoder is also included. The second driving unit 31 is a stepping motor. The encoder is electrically connected to the stepping motor and is used to record the rotation angle of the stepping motor.

[0079] Specifically, the encoder is electrically connected to the stepper motor to encode and count the stepper motor's rotation, thereby recording the stepper motor's rotation. In this embodiment, the stepper motor and encoder are also electrically connected to a control unit, which is electrically connected to the image capture mechanism 4. Each time the stepper motor is driven, the connected turntable 32 rotates one angle, and the control unit controls the image capture mechanism 4 to capture an image of the filter end of the cigarette.

[0080] After one rotation, the second proximity switch detects the second trigger member. After receiving the second trigger signal from the second proximity switch, the control unit controls the stepper motor to stop driving and controls the image acquisition mechanism 4 to stop acquiring images. The image acquisition mechanism 4 completes the image acquisition of one circle of the filter tip end.

[0081] Furthermore, the image acquisition mechanism 4 includes:

[0082] The image acquisition unit 41 is provided on one side of the clamping mechanism 2 and is used to acquire an image of the filter of the cigarette;

[0083] The light source unit 42 is provided below the clamping mechanism 2 and is used to emit light, with the axial direction of the light source being consistent with the axial direction of the cigarette;

[0084] A third driving unit 43;

[0085] The light source fixing seat 44 is connected to the driving end of the third driving unit 43, and is used to drive the light source fixing seat 44 to move back and forth in the horizontal direction, wherein the light source unit 42 is fixed on the light source fixing seat 44, and a horizontal light-transmitting plate 441 for projecting the light source is provided above the light source fixing seat 44. When the clamping mechanism 2 clamps the cigarette, the filter end of the cigarette rests on the horizontal light-transmitting plate 441.

[0086] Specifically, in this embodiment, the image acquisition unit 41 is a CCD industrial camera, which acquires the image of the filter by taking pictures.

[0087] The axis of the light source emitted by the light source unit 42 is consistent with the axis of the cigarette. The light source unit 42 provides a bright light beam coaxial with the vertical cigarette for taking pictures. When the light beam passes through the punching position, it will be emitted outward through the hole. When the camera takes pictures, it can better capture the information of the hole and avoid misjudgment due to the dimness of some holes.

[0088] This technical solution can improve the accuracy of detection by detecting the punching quality through taking pictures with a camera.

[0089] Furthermore, a photoelectric detection sensor is provided above the horizontal light-transmitting plate 441 for detecting whether there is a cigarette on the horizontal light-transmitting plate 441 .

[0090] Specifically, in this embodiment, the photoelectric detection sensor is electrically connected to the control unit. The photoelectric sensor is positioned above the horizontal light-transmitting plate 441, i.e., below the clamping mechanism 2. The detection end of the photoelectric detection sensor is directed toward the cigarette held by the clamping mechanism 2. When the photoelectric detection sensor detects a cigarette, it sends a cigarette detection signal to the control unit. Upon receiving the cigarette detection signal, the control unit energizes the first drive unit 24 to retract the blocking rod 25 and activates the second drive unit 31 to rotate the clamping mechanism 2.

[0091] Optionally, the photoelectric detection sensor is a diffuse reflection sensor.

[0092] Furthermore, it also includes a recovery unit 5, which is arranged below the clamping mechanism 2 and is used to collect the cigarettes that have been tested.

[0093] Optionally, a display unit is further included, and both the image acquisition unit 41 and the display unit are electrically connected to the control unit. The image acquired by the image acquisition unit 41 can be displayed on the display unit.

[0094] The operating principle of the cigarette perforation quality inspection device provided by this utility model is as follows: multiple cigarettes are placed horizontally in the hopper 11. The rotary drive unit 13 drives the divider 12 to rotate. As the divider 12 rotates, the cigarettes fall into the cigarette receiving slot 121. Each time the divider 12 rotates, a cigarette is dropped. The dropped cigarette is guided by the guide 141 within the drop channel 14, changing from a horizontally extended state to a vertically extended state. It then falls out of the channel opening at the lower end of the drop channel 14. The cigarette passes through the through-holes of the connecting turntable 32 and falls into the clamping mechanism 2, landing on the horizontal light-transmitting plate 441. When the photoelectric detection sensor detects a cigarette, the first drive unit 24 retracts the stopper 25, the first and second clamping members 21 and 22 clamp the cigarette, and the second drive unit 31 begins to rotate the connecting turntable 32, causing the cigarette to rotate accordingly. At this point, the light source unit 42 is aligned with the cigarette filter, providing a light beam for photographing. Simultaneously, the image acquisition unit 41 is activated to capture an image of the cigarette filter. After the cigarette has rotated 360°, the second proximity switch detects the second trigger, completing image capture of the cigarette. The first drive unit 24 then extends the blocking rod 25 to abut against the end of the first clamping member 21, providing a force opposing the elastic member 23 to the first clamping member 21, thereby releasing the cigarette from the first and second clamping members 21 and 22. At this point, the third drive unit 43 drives the light source holder 44 away from the cigarette's location. As a result, the cigarette is released and, after inspection, falls into the recovery unit 5.

[0095] The cigarette punching quality detection device provided by the utility model avoids manual detection, realizes automation of detection, and improves detection efficiency and detection accuracy.

[0096] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above description is provided to further illustrate the present invention in conjunction with specific embodiments, and that the present invention should not be construed as being limited to these descriptions. Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
