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 strip-shaped hole belt of a tipping paper. Background Art

[0002] When tobacco burns, tar, nicotine and carbon monoxide are produced. In order to reduce the harm of these substances to the human body when smoking, the tipping paper used for cigarettes adopts laser punching technology. The tipping paper after laser punching has a certain degree of air permeability. The degree of air permeability can effectively control the content of harmful substances such as tar, nicotine, carbon monoxide produced when smoking, and it is an important indicator for detecting 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: use an image sensor and a background light source to take pictures of the laser holes on the tipping paper, then calculate the total area of ​​the micropores in the micropore arrangement image, and obtain the air permeability of the tested tipping paper based on the relationship between the area and the 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 so that it returns to normal.

[0004] The existing laser drilling equipment uses a camera to directly photograph 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 taken by the camera and 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.

[0050] Reference Figure 1 , Figure 2 and Fig.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 a guide roller to pass through the second opening 13 on the side where the detection box is located, 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.

In this way, the movement of the dust collection component and the shooting component can be controlled separately by utilizing the extension and contraction of the first cylinder 2 and the second cylinder 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 in position, further optimized design is carried out.

[0054] like Fig.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 and extends obliquely toward the outer side of the track 55, and the end of the second groove 58 passes through the outer wall of the track 55 to form a docking gap 59. Fig.14 As shown, a connecting plate 41 is provided at the bottom side of the bottom rail 4, and a hole is opened on the connecting plate 41, and the connecting plate 41 is used to fix the bottom rail 4 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 arranged symmetrically in an eight-shaped shape, two of which are arranged in the dust removal chamber 1a, and the other two are arranged in the detection chamber 1b. When the support plate 6 descends, the mounting plate 5 also rotates and descends, so that the track 55 gradually approaches 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, so as to adjust and change 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 kraft paper 10 for vacuuming, 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, the two ends of the slide 8 are respectively provided with sliders 81, which are arranged in the first groove 57, and the two ends of the slider 81 are respectively provided with elastically compressible ball assemblies, which are close to the first groove 57 and compressed into the slider 81, that is, when the slider 81 is located in the first groove 57, the ball assembly is compressed, thereby squeezing and pressing the slider 81, ensuring that the slide 8 can be initially fixed on the track 55. When the track 55 is docked with the bottom rail 4, the slider 81 slides to the bottom rail 4, and the ball assembly is reset and fits on the inner wall of the bottom rail 4 to roll. Since the slider 81 slides through the first groove 57 to the second groove 58 when sliding, the inclined second groove 58 plays a transitional role at this time, and the ball assembly can be gradually reset. When the slider 81 completely reaches the bottom rail 4, the ball assembly is released from the compressed state at this time, and it can just stick to the side wall of the bottom rail 4 and slide smoothly. This structure can ensure that the slide seat 8 is both fixed and slided. 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 transferred 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 seat 8, and an arc-shaped clamping rod 66 is extended from the connecting head 64 at the end of the track 55, and the clamping rod 66 can be fixed on the connecting head 64 by threaded connection. Figure 7 When the slider 81 is arranged in the first groove 57, the support plate 6 can rise and drive the clamping rod 66 to rotate toward the slide seat 8 and clamp into the positioning clamping groove 821. In this way, when the dust collection component reaches the dust collection position, when the shooting component reaches the shooting position, the clamping and locking can be automatically realized to prevent the slider 81 from extending due to the abnormality of the telescopic mechanism and causing a collision with the moving tipping paper 10.

[0057] like Figures 3 to 18As shown, further, the two ends of the slider 81 are respectively provided with mounting holes 82, and the mounting holes 82 are connected with the positioning slot 821. The ball assembly includes a slide post 84, a ball 85 and a spring 86. The end of the slide post 84 is rotatably provided with the ball 85, and one end of the slide post 84 is provided with a spring 86. The slide post 84 and the spring 86 are arranged in the mounting hole 82, and the spring 86 is located at the positioning slot 821. In this structure, the mounting hole 82 and the positioning slot 821 where the ball assembly is installed are arranged at the same position, and the two are linked to each other to achieve a better locking effect. When the slider 81 is arranged in the first groove 57, the ball 85 assembly is compressed, and the spring 86 is compressed, and the slider 8 can be initially fixed; and at this time, the clamping rod 66 can be clamped into the positioning slot 821, and the end of the clamping rod 66 is clamped in the gap of the spring 86, so that the clamping rod 66 can be clamped 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, so as to facilitate the clamping into the gap of the spring 86 with little effort.

[0064] Example 4

[0065] A method for detecting a strip-shaped hole band of a tipping paper comprises 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 assembly and the shooting assembly 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 micro-pore shooting is performed in the detection chamber 1b.

[0067] S2, such as Figure 4 As shown, the shooting is continuously performed during the continuous conveying of the tipping paper 10. After a fixed shooting time, the first cylinder 2 extends to rotate the track 55 in the detection chamber 1b and dock with the bottom rail 4. The telescopic mechanism is used to control the extension of the third cylinder 7 to move the shooting assembly inside the detection chamber 1b to the bottom side of the box body 1 for maintenance to ensure the shooting clarity of the camera 3. When the slide 8 is transferred from the track 55 to the bottom rail 4, the shooting assembly gradually descends and finally reaches the position of the third opening 15 on the bottom side, and the shooting assembly can be maintained through this position.

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