Description

Technical Field

[0001] The invention belongs to the technical field of tobacco detection equipment, and in particular relates to a detection device and method for a tipping paper strip-shaped hole belt. Background Art

[0002] When tobacco burns, it produces tar, nicotine and carbon monoxide. In order to reduce the harm of these substances to the human body when smoking, the tipping paper used in cigarettes adopts laser punching technology. The tipping paper after laser punching has a certain degree of air permeability. The size of the air permeability can effectively control the content of harmful substances such as tar, nicotine, carbon monoxide produced when smoking, and is an important indicator for testing the quality of perforated tipping paper.

[0003] At present, one of the methods for online detection of the air permeability of laser-punched tipping paper is: using an image sensor and a background light source to capture the laser holes on the tipping paper, and then calculating the total area of ​​the micropores in the micropore arrangement image, and obtaining the air permeability of the tested tipping paper based on the relationship between area and air permeability. If the air permeability is within the allowable deviation range, it is normal. If the air permeability is close to the allowable deviation, it is necessary to adjust the punching process parameters to correct the air permeability deviation and return it to normal.

[0004] The existing laser drilling equipment uses a camera to directly capture the laser holes on the tipping paper after punching. During the online production of tipping paper, punching waste, dust, etc. accumulate in the holes during laser drilling, resulting in blurred punching images captured by the camera and the inability to correctly calculate the micropore area. Secondly, the camera is exposed for a long time, and once the lens is contaminated with dust, etc., it will further affect the clarity of the shooting and the accuracy of the air permeability detection.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figures 1 to 13 As shown, a device for detecting perforated tapes in corking paper strips includes a box body 1, a dust collection component, a shooting component, and the like.

[0045] like Figures 1 to 18As shown, a partition 11 is provided inside the housing 1 to separate the interior of the housing 1 into a dust removal chamber 1a and a detection chamber 1b. Mounting plates 5 are hingedly connected at both ends of the partition 11. The mounting plates 5 are hingedly connected to a support plate 6. The support plate 6 is provided on the bottom side of the mounting plate 5, and the bottom end of the support plate 6 slides on the inner wall of the partition 11. Two rails 55 are symmetrically provided at the ends of the mounting plate 5. Slides 8 are slidably provided on the rails 55. The dust collection assembly is provided on the slide 8 located inside the dust removal chamber 1a, and the camera assembly is provided on the slide 8 located inside the detection chamber 1b. Bottom rails 4 are symmetrically provided inside the housing 1. The number of bottom rails 4 is the same as the number of rails 55. The bottom ends of the bottom rails 4 extend outside the housing 1, and the rails 55 can rotate and dock with the bottom rails 4. A telescopic mechanism is provided on the mounting plate 5. The telescopic mechanism located inside the dust removal chamber 1a is connected to the dust collection assembly for transmission, while the telescopic mechanism located inside the detection chamber 1b is connected to the camera assembly for transmission.

[0046] In the present invention, tipping paper 10 is placed within a closed box 1. A vacuum assembly is used to vacuum the perforated tipping paper 10. After vacuuming is complete, a camera assembly is used to photograph the perforations. This method removes punching debris and dust accumulated in the holes during laser drilling, ensuring the accuracy of the perforation images captured by camera 3. Furthermore, camera 3 is protected to ensure clarity and accuracy of the images captured, ensuring the accuracy of air permeability testing.

[0047] Secondly, continuous photography is performed during the continuous conveying of the tipping paper 10. After a fixed period of photography, the track 55 in the detection chamber 1b is periodically rotated and docked with the bottom rail 4. Using a telescopic mechanism, the photography assembly located within the detection chamber 1b is moved to the bottom side of the box body 1 for maintenance, ensuring the reliability of the camera 3 and ensuring that the camera 3 always provides clear and reliable photography performance throughout the complete production process of the tipping paper 10. This structure improves the accuracy of air permeability testing in two ways: first, it removes punching dust and debris, eliminating the impact of the tipping paper 10 itself on the air permeability test; second, it protects the main body of the testing equipment and regularly moves and maintains it, eliminating the impact of the testing equipment on the air permeability test.

[0048] Reference Figures 3 to 8 、 Figure 17 、 Figure 18 In the present invention, the telescopic mechanism is driven by a pneumatic cylinder and includes a third cylinder 7. A cylinder accommodating groove 52 is provided within the mounting plate 5. Connecting flanges 53 are provided on both sides of the cylinder accommodating groove 52. The third cylinder 7 is detachably connected to the connecting flanges 53. A through-hole 54 is provided in the center of the mounting plate 5. A third piston rod 71 of the third cylinder 7 extends through the through-hole 54. One end of the third piston rod 71 is connected to the slide 8, which is driven to move by the third cylinder 7. A clearance groove 63 is provided on one side of the support plate 6 to prevent motion interference with the shooting and vacuum components.

[0049] Reference Figures 3 to 8 、 Figures 16 to 18 Specifically, mounting grooves 16 are vertically provided on both sides of the partition 11, and a first hinge hole 18 is provided at the upper end of the mounting groove 16. A first pin 51 is provided at one end of the mounting plate 5, and the first pin 51 is rotatably provided in the first hinge hole 18. Slide grooves 17 are vertically provided on both sides of the mounting groove 16, and a second pin 61 is provided at one end of the support plate 6, and the second pin 61 is slidably provided in the slide groove 17. Among them, two tracks 55 are symmetrically provided on one side of the mounting plate 5, and a second hinge hole 56 is provided on the track 55. A connector 64 is symmetrically provided on one end of the support plate 6, and a third pin 65 is provided on the outer side of the connector 64, and the third pin 65 is rotatably provided in the second hinge hole 56.

[0050] Reference Figure 1 、 Figure 2 and Figure 16 A first opening 12 is provided on both sides of the box body 1, and a second opening 13 is provided on the upper end of the box body 1. The tipping paper 10 enters the dust removal chamber 1a from the first opening 12 on one side, passes through the second opening 13 on the side where the dust removal chamber 1a is located, and then is guided by the guide roller to pass through the second opening 13 on the side where the detection box is located into the detection chamber 1b, and finally passes through the first opening 12 on the side where the detection chamber 1b is located, and finally passes through the first opening 12 on the side where the detection chamber 1b is located. Figure 2 The arrows shown indicate the conveying direction of the tipping paper 10. A third opening 15 is provided on the opposite side of the bottom of the box body 1, through which one end of the bottom rail 4 extends obliquely to the bottom side of the box body 1.

[0051] Reference Figure 1 、 Figure 2 and Figure 16 In the present invention, the lifting and lowering of the support plate 6 is achieved using pneumatic cylinders. Two cylinder mounting holes are provided at the bottom end of the partition 11, each housing a first cylinder 2 and a second cylinder 22. Fourth openings 14 for piston rods are symmetrically provided on the bottom side of the housing 1. These fourth openings 14 are positioned opposite the slide slots 17 on either side of the partition 11. The first piston rod 21 of the first cylinder 2 bends through the fourth opening 14 and extends into the dust removal chamber 1a. The second piston rod 23 of the second cylinder 22 bends through the other fourth opening 14 and extends into the detection chamber 1b. A through slot 62 is provided at one end of the support plate 6, creating a hollowed-out middle section of the second pin 61. The distal end of the first piston rod 21 is hinged upwardly to the second pin 61 located within the dust removal chamber 1a, while the distal end of the second piston rod 23 is hinged upwardly to the second pin 61 located within the detection chamber 1b. This allows the movement of the dust collection assembly and the camera assembly to be independently controlled by the extension and retraction of the first and second cylinders 22.

[0052] Example 2

[0053] In order to further enhance the locking effect of the dust suction component and the shooting component after they are in place, and to ensure that the dust suction component and the shooting component can be smoothly moved and adjusted, further optimization design is carried out.

[0054] like Figure 17 As shown, a first groove 57 is provided on the inner side of the track 55, and a second groove 58 is provided at the end of the first groove 57, which extends obliquely toward the outside of the track 55. The end of the second groove 58 passes through the outer wall of the track 55 to form a docking gap 59. Figure 14 As shown, a connecting plate 41 is provided on the bottom side of the bottom rail 4, and a hole is opened on the connecting plate 41, which is fixed to the inner wall of the box body 1. A docking portion 42 is extended from one end of the bottom rail 4. Figure 4 , the four bottom rails 4 are symmetrically arranged in an eight-shaped shape, two of which are set in the dust removal chamber 1a, and the other two are set in the detection chamber 1b. When the support plate 6 descends, the mounting plate 5 also rotates and descends, causing the track 55 to gradually approach the bottom rail 4 until the track 55 docks with the bottom rail 4, that is, the track 55 and the bottom rail 4 are parallel, and the end of the track 55 is close to the inner wall of the docking portion 42. At this time, the docking notch 59 is blocked and covered by the docking portion 42, so that the track 55 and the bottom rail 4 are seamlessly docked. In this way, the slide 8 set on the track 55 can be moved to the bottom rail 4 through the telescopic mechanism, thereby adjusting and changing the position of the dust collection component and the shooting component. Figure 4 As shown, at this time, the vacuuming component is close to the tipping paper 10 to vacuum, and the shooting component extends downward and reaches the bottom side of the box body 1 through the third opening 15 for maintenance operations. The shooting component is moved out of the box body 1 through the third opening 15, and the lens of the camera 3 can be inspected, and the lens of the camera 3 can be wiped and cleaned, etc., to ensure the clarity of the image taken by the camera 3.

[0055] like Figures 3 to 18As shown, further, sliders 81 are provided at both ends of the slide 8. Sliders 81 are fitted within the first groove 57. Elastically compressible ball assemblies are provided at both ends of the slider 81. The ball assemblies cling tightly to the first groove 57 and are compressed within the sliders 81. That is, when the sliders 81 are within the first groove 57, the ball assemblies are compressed, squeezing and pressing the sliders 81, ensuring that the slide 8 can be initially fixed to the track 55. When the track 55 is docked with the base rail 4, the sliders 81 slide onto the base rail 4, and the ball assemblies return to their original position, rolling against the inner wall of the base rail 4. As the slider 81 slides through the first groove 57 and reaches the second groove 58, the inclined second groove 58 acts as a transition, allowing the ball assemblies to gradually return to their original position. When the slider 81 fully reaches the base rail 4, the ball assemblies are released from their compressed state, allowing them to slide smoothly against the sidewalls of the base rail 4. This structure can ensure that the slide 8 is both fixed and sliding. When it is set on the track 55, it can be stably fixed. When it is away from the track 55, it can be stably and smoothly transitioned to the bottom rail 4.

[0056] like Figures 3 to 18 As shown, further, positioning slots 821 are provided on both sides of the slide 8, and an arc-shaped clamping rod 66 is extended from the connector 64 at the end of the track 55. The clamping rod 66 can be fixed on the connector 64 by means of a threaded connection. Figure 7 When the slider 81 is fitted into the first groove 57, the support plate 6 can rise and drive the engaging rod 66 to rotate toward the slide 8 and engage into the positioning groove 821. In this way, when the dust collection component reaches the dust collection position and when the shooting component reaches the shooting position, the locking mechanism can be automatically achieved, preventing the slider 81 from extending due to an abnormality in the telescopic mechanism and causing a collision with the moving tipping paper 10.

[0057] like Figures 3 to 18As shown, the slider 81 further comprises mounting holes 82 at both ends, which communicate with the positioning slot 821. The ball assembly comprises a slide post 84, a ball 85, and a spring 86. The ball 85 is rotatably mounted at the end of the slide post 84, and a spring 86 is mounted at one end of the slide post 84. The slide post 84 and the spring 86 are disposed in the mounting hole 82, with the spring 86 located in the positioning slot 821. This structure places the mounting hole 82 for the ball assembly and the positioning slot 821 in the same position, and the two interact with each other, achieving a better locking effect. When the slider 81 is positioned within the first groove 57, the ball 85 assembly is compressed, and the spring 86 is compressed, thereby achieving a preliminary fixation of the slider 8. At this point, the clamping rod 66 can be inserted into the positioning slot 821, with the end of the clamping rod 66 being trapped within the gap in the spring 86. This allows the clamping rod 66 to be engaged in the middle section of the spring 86, further limiting the compressibility of the spring 86 and achieving a better locking effect. The end of the clamping rod 66 is provided with a conical tip, which facilitates the clamping into the gap of the spring 86 with little effort.

[0058] Example 3

[0059] like Figures 3 to 18 As shown, in the present invention, the dust removal component includes a bellows 91 and a plurality of suction nozzles 9 arranged on the bellows 91. The bellows 91 is detachably fixed on the slide 8. The suction nozzles 9 are arranged in a triangular shape. There are two suction nozzles 9. The suction nozzles 9 are arranged along the length direction of the tipping paper 10 for suction.

[0060] like Figures 3 to 18 As shown, in the present invention, the shooting assembly includes a camera 3 and a camera seat 31 arranged on the camera 3. A clamp 35 is provided on the camera 3. One side of the clamp 35 has a hinge part 351. The hinge part 351 is hinged to the mounting seat 33. The camera seat 31 and the mounting seat 33 are respectively detachably connected to the slide 8.

[0061] Furthermore, a strip-shaped mounting groove 83 is provided on the slide 8 , and a plurality of screws are provided on the bellows 91 , the camera seat 31 and the mounting seat 33 , and the screws are arranged in the strip-shaped mounting groove 83 .

[0062] Reference Figure 9 and Figure 10 Four first screws 93 are provided at the upper end of the bellows 91. The first screws 93 pass through the strip mounting groove 83 in pairs and are screwed into nuts for fixing. This fixing method facilitates the horizontal adjustment of the position of the suction nozzle 9 so that it can be sucked according to the punching position of the tipping paper 10.

[0063] Reference Figures 11 to 13Two second screws 32 are provided on the camera seat 31, and two third screws 34 are provided on the mounting seat 33. The second screws 32 and the third screws 34 are passed through the strip mounting groove 83 in pairs and screwed into nuts to fix them. The camera seat 31 and the mounting seat 33 are used to stably fix the camera 3.

[0064] Example 4

[0065] A method for detecting a strip of perforated tape in tipping paper, comprising the following steps:

[0066] S1, such as Figure 2 and Figure 3 As shown, by contracting the first cylinder 2 and the second cylinder 22, the support plate 6 is controlled to rise, so that the dust collection component and the shooting component move up and close to the tipping paper 10, and the conveying device starts to convey the tipping paper 10, and laser drilling and dust removal are performed in the dust removal chamber 1a, and micropore shooting is performed in the detection chamber 1b in turn.

[0067] S2, such as Figure 4 As shown, continuous filming is performed while tipping paper 10 is continuously conveyed. After a fixed filming time, first cylinder 2 extends, rotating track 55 within detection chamber 1b and aligning it with bottom rail 4. A telescopic mechanism, controlling the extension of third cylinder 7, moves the camera assembly within detection chamber 1b to the bottom of housing 1 for maintenance, ensuring clarity of the images captured by camera 3. As slide 8 transfers from track 55 to bottom rail 4, the camera assembly gradually descends, ultimately reaching third opening 15 on the bottom side, allowing maintenance operations to be performed on the camera assembly.

[0068] S3, after each camera 3 maintenance is completed, the shooting component is moved to the bottom side of the tipping paper 10 for shooting again. When a roll of tipping paper 10 is completely laser punched and air permeability tested, the dust collection component and the shooting component can be moved out of the box 1 for inspection and maintenance.

[0069] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
