[0003] Before cigarette packaging paper is made into packaging boxes, it is necessary to print graphics on the surface of the paper. At present, the printing and production of cigarette packaging paper also adopts a variety of process technologies. Therefore, after the graphics are printed, the printed area of ​​the cigarette packaging paper needs to be inspected to determine whether the printed graphics on the cigarette packaging paper are clear. Currently, most commonly used detection methods use graphic printing imaging technology to capture whether the graphics on the cigarette packaging paper are blurry or have ghosting phenomena. However, the graphics printed on some cigarette packaging papers are often normal in a non-contact state. Once the graphics on the cigarette packaging paper are contacted and rubbed by external objects, the printed graphics will immediately become blurred, which often leads to inaccurate detection results, thereby causing unqualified printed graphics on the cigarette packaging paper to flow into the subsequent use process.

[0013] A device and method for detecting graphic printing on cigarette packaging paper, comprising the following steps:

[0014] S1: The cigarette wrapping paper is conveyed to the processing table, and a plurality of stoppers arranged symmetrically in pairs are used to limit the position of the cigarette wrapping paper from both sides to prevent the paper from tilting or deviating.

[0015] S2: The driving motor starts to drive the guide rod and the two first guide wheels to rotate slightly by a certain angle, and the second guide wheel, the third guide wheel and the corresponding sleeve are driven to rotate synchronously through the transmission action of the transmission belt. The second guide wheel, the third guide wheel and the corresponding sleeve descend in a spiral shape on the guide rod, driving the support plate and the two spreading plates below to squeeze the cigarette packaging paper.

[0016] S3: As the guide rod rotates, it will drive the adjustment support plate to rotate synchronously. The two ends of the adjustment support plate will tilt and push the two traction parts, so as to drive the two horizontal plates and the spreading plate to press down and move backwards to squeeze and translate the printed images on the cigarette packaging paper. This simulates the cigarette packaging paper being squeezed by external objects after being packaged in the box in the processing factory and generating moving friction.

[0017] S4: The driving motor reverses to drive the guide rod and the two first guide wheels to reverse, and under the transmission action of the transmission belt, the second guide wheel and the third guide wheel and the corresponding sleeve rise in a spiral on the guide rod, and drive the support plate and the two spreading plates below to separate from the squeezed cigarette packaging paper. During the rising and approaching process of the spreading plates, the graphic printing detector can detect the clarity of the printed graphics on the cigarette packaging paper below through the through slot to determine whether the graphics are blurred.

[0018] S5: By applying conveying equipment to carry out translational conveying of cigarette packaging paper during processing, and combining with the repeated operation of the drive motor, two spreading plates can be used to perform multiple extrusion and translational friction on the surface of the cigarette packaging paper. In this way, the printed images on the entire cigarette packaging paper can be simulated by first performing an extrusion and friction experiment and then performing a clarity detection operation.

[0019] The at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0020] First, the support plate is driven down by the operation of the lifting drive mechanism, so that the two sets of flattening components descend and gradually contact the graphic printing area on the cigarette packaging paper. At the same time, and under the synchronous operation of the adjustment mechanism, the two sets of flattening components will move back to back after contacting the graphic printing area on the cigarette packaging paper, and implement a friction and smoothing contact state on the graphic printing area, so that the graphic printing area on the cigarette packaging paper can obtain a friction state similar to that of contact with an external object. The graphic printing detector then performs a clarity test on the graphic printing area on the packaging paper to determine whether the printed graphic area on the cigarette packaging paper is blurred or has ghosting phenomena.

[0021] Secondly, the drive motor can drive the guide rod and the two first guide wheels to rotate slightly by a certain angle, so that the second guide wheel and the third guide wheel, which are connected to the two first guide wheels by the transmission belt, will rotate synchronously, and then slowly descend in a spiral state on the screw, driving the entire support plate to descend, so that the flattening component under the support plate descends and gradually contacts the printed graphic area on the cigarette packaging paper, thereby simulating the contact and extrusion of the cigarette packaging paper with external objects after being packaged in the box at the processing factory;

[0022] After completing the simulated extrusion, the drive motor reverses and drives the guide rod and the two first guide wheels to reverse, so that the transmission belt drives the second guide wheel, the third guide wheel and the corresponding sleeve to reverse, and slowly rises in a spiral trajectory on the screw to drive the entire support plate and the flattening component below to immediately separate from the squeezed cigarette packaging paper, so that the graphic printing detector on the flattening component can detect the printed graphic area on the cigarette packaging paper to determine whether the graphic on the paper is clear and not blurred.

[0023] Third, when the guide rod rotates, it will drive the adjustment support plate to rotate synchronously, so that when the two ends of the adjustment support plate tilt, they will push the traction parts connected in rotation at both ends, and drive the corresponding two horizontal plates to gradually move away, so that the two spreading plates in the slowly descending state will move back to back, thereby contacting the cigarette packaging paper and smoothing it from the middle to both sides in a downward state, so as to simulate the cigarette packaging paper being squeezed by external objects after being packaged in the box in the processing factory and generating moving friction, so that the graphics and text on the cigarette packaging paper can undergo a friction experiment.

[0024] Fourthly, after the two spreading plates in the present invention perform the pressing and translation operations, they can perform multiple rolling and flattening operations on the curved parts of the cigarette packaging paper, thereby restoring the curved parts of the cigarette packaging paper to a flat state.

[0039] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] The embodiment of the present invention provides a device for detecting graphic printing on cigarette packaging paper, comprising a processing table 1 and a graphic printing detector 11, and further comprising a bracket 2, wherein the bracket 2 is horizontally placed on the processing table 1, and the bracket 2 is a certain distance away from the working table of the processing table 1, and both ends of the bracket 2 are bent and extended downward and are fixedly connected to the working table of the processing table 1, and a support plate 21 is horizontally placed below the bracket 2, and both ends of the support plate 21 are respectively slidably matched with the inner sides of the bent and extended parts of the two ends of the bracket 2. A lifting drive mechanism 3 is provided on the support plate 21 for driving the support plate 21 to be lifted and lowered below the bracket 2, and two groups of flattening components 4 arranged in a symmetrical state are provided below the support plate 21, and an adjustment mechanism 5 for driving the flattening component 4 to operate is provided between the support plate 21 and the flattening component 4, and a graphic printing detector 11 for detecting the clarity of the graphic printing area is provided on the flattening component 4;

[0042] During use, the cigarette packaging paper with graphic printing can be transported to the work surface of the processing table 1 and moved to the lower part of the flattening component 4. Then the lifting drive mechanism 3 is operated to drive the support plate 21 to descend, so that the two groups of flattening components 4 descend and gradually contact the graphic printing area on the cigarette packaging paper. At the same time, and under the synchronous operation of the adjustment mechanism 5, the two groups of flattening components 4 will move back to back after contacting the graphic printing area on the cigarette packaging paper, and implement friction and smoothing contact state on the graphic printing area, so that the graphic printing area on the cigarette packaging paper can obtain a friction state similar to that of contact with an external object. Secondly, when the two groups of flattening components 4 move on the cigarette packaging paper, the graphic printing detector 11 will immediately perform clarity detection on the graphic printing area on the packaging paper to determine whether the printed graphic area on the cigarette packaging paper is blurred or has ghosting phenomena.

[0043] At the same time, this device is also installed in the physical production equipment assembly line of cigarette packaging paper. If the graphic printing area on the cigarette packaging paper shows blurring and ghosting, the cigarette packaging paper will be immediately taken out and marked as defective. If the graphic printing area on the cigarette packaging paper is normal and not blurred, it will be directly transferred to the subsequent processing flow, thereby bringing more accurate detection results in the graphic printing processing of cigarette packaging paper, avoiding the flow of unqualified cigarette packaging paper printed graphics into the subsequent use process.

[0044] Preferably, the lifting drive mechanism 3 includes a guide rod 31, a first guide wheel 32, a second guide wheel 33 and a third guide wheel 34. The guide rod 31 is vertically arranged in the middle part of the support plate 21, and the two ends of the guide rod 31 are rotatably connected to the bracket 2 and the support plate 21 respectively. There are two first guide wheels 32 and they are arranged on the guide rod 31 in an upper and lower sorting state. The two first guide wheels 32 are both located between the support plate 21 and the bracket 2, and the center parts of the two first guide wheels 32 are fixedly connected to the guide rod 31. The second guide wheel 33 and the third guide wheel 34 are respectively arranged at the two end parts of the support plate 21, wherein the second guide wheel 33 and the two first guide wheels are connected to the guide rod 31. The first guide wheel 32 at the upper position among the two first guide wheels 32 is in a horizontal corresponding position, and the third guide wheel 34 is in a horizontal corresponding position with the other first guide wheel 32. A transmission belt 35 is provided on the first guide wheel 32 at the upper position and the second guide wheel 33 among the two first guide wheels 32, and a transmission belt 35 is also provided on the first guide wheel 32 at the lower position and the third guide wheel 34 among the two first guide wheels 32. A drive motor 36 is provided on the bracket 2 above the guide rod 31. The output end of the drive motor 36 is downwardly arranged and fixedly connected to the top end of the guide rod 31. The drive motor 36 is controlled by a matching controller to perform operation instructions.

[0045] A sleeve 37 is provided below the second guide wheel 33. The top end of the sleeve 37 is fixedly connected to the bottom end of the second guide wheel 33, and the bottom end of the sleeve 37 is rotatably connected to the support plate 21. The bottom end of the third guide wheel 34 is rotatably connected to the support plate 21. A sleeve 37 is provided above the third guide wheel 34. The top end of the sleeve 37 is spaced a certain distance from the bracket 2, and the bottom end of the sleeve 37 is fixedly connected to the top end of the third guide wheel 34.

[0046] The second guide wheel 33 and the third guide wheel 34 are each vertically provided with a screw 38, each of which passes through the second guide wheel 33, the third guide wheel 34, the sleeve 37 and the support plate 21 respectively. A support plate 39 is extended and fixedly provided on the bracket 2 below each screw 38, and the two ends of each screw 38 are fixedly connected to the inner top of the bracket 2 and the corresponding support plate 39 respectively. The second guide wheel 33, the third guide wheel 34 and the sleeve 37 are provided with matching thread grooves at the parts that contact the corresponding screw 38, so that the second guide wheel 33 and the corresponding sleeve 37, as well as the third guide wheel 34 and the sleeve 37, can respectively perform synchronous up and down thread matching movement on the corresponding screw 38;

[0047] By operating the controller to give an operation instruction to the drive motor 36, the output end of the drive motor 36 operates to drive the guide rod 31 and the two first guide wheels 32 to rotate slightly by a certain angle. At this time, the second guide wheel 33 and the third guide wheel 34, which are transmission-connected to the two first guide wheels 32 through the transmission belt 35, will rotate synchronously, and then drive the sleeves 37 corresponding to the second guide wheel 33 and the third guide wheel 34 to produce spiral movement on the screw 38. Since the sleeves 37 connected to the second guide wheel 33 and the third guide wheel 34 are rotationally connected to the entire support plate 21, when the second guide wheel 33 and the third guide wheel 34 and the corresponding sleeves 37 slowly descend along a spiral trajectory on the screw 38, they will drive the entire support plate 21 to descend, and cause the flattening assembly 4 below the support plate 21 to descend and gradually contact the printed image area on the cigarette packaging paper, so that the image on the cigarette packaging paper can be pressed down by the flattening assembly 4, thereby simulating the contact and extrusion of the cigarette packaging paper with external objects after being packaged in the processing factory;

[0048] After the flattening component 4 completes a downward pressing operation on the cigarette packaging paper, the controller controls the output end of the drive motor 36 to reverse, and drives the guide rod 31 and the two first guide wheels 32 to reverse. At this time, under the action of the transmission belt 35, the second guide wheel 33 and the third guide wheel 34 and the corresponding sleeve 37 can be driven to reverse, so that the second guide wheel 33 and the third guide wheel 34 and the corresponding sleeve 37 slowly rise in a spiral trajectory on the screw 38, and drive the entire support plate 21 to rise, so that the flattening component 4 under the support plate 21 immediately separates from the squeezed cigarette packaging paper. As the flattening component 4 rises, the graphic printing detector 11 on the flattening component 4 can detect the printed graphic area on the cigarette packaging paper to determine whether the graphic on the paper is clear and not blurred.

[0049] Preferably, the flattening assembly 4 includes a transverse plate 41 and a flat spreading plate 42, and two of the transverse plates 41 and the flat spreading plates 42 are provided. The two transverse plates 41 are arranged in a transversely symmetrical state at the front and rear side parts below the support plate 21, and the two flat spreading plates 42 are fixedly arranged at the bottom of the two transverse plates 41, respectively. The upper and lower sides of each flat spreading plate 42 are bent and laterally extended for a distance, and the upper and lower bent and laterally extended parts of the flat spreading plate 42 are both flat surfaces, so that the cross section of the flat spreading plate 42 forms a C-shaped structure. A through groove 43 is provided on the lower flat surface part of each flat spreading plate 42, and the graphic printing detector 11 is fixedly arranged on the inner side surface of the flat spreading plate 42 after being bent, and the detection end of the graphic printing detector 11 is facing the through groove 43;

[0050] A baffle 44 is fixedly provided below the support plate 21 and at the outer end of each transverse plate 41 , and the outer end of each transverse plate 41 is slidably fitted with the corresponding baffle 44 ;

[0051] When the two spreading plates 42 descend, the bent flat surface below the spreading plates 42 will gradually come into contact and squeeze with the surface of the cigarette wrapping paper. As the two spreading plates 42 rise and separate from the cigarette wrapping paper, the graphic printing detectors 11 on the two spreading plates 42 can detect the clarity of the graphic on the cigarette wrapping paper below through the through slots 43 to determine whether the graphic on the paper is blurred.

[0052] Preferably, the adjustment mechanism 5 includes an adjustment support plate 51 and two traction members 52. The adjustment support plate 51 is located below the support plate 21. The bottom end of the guide rod 31 passes through the support plate 21 and then extends downward and is fixedly connected to the middle part of the adjustment support plate 51. The two traction members 52 are respectively provided at both ends of the adjustment support plate 51. One end of the two traction members 52 is rotatably connected to the two ends of the adjustment support plate 51, and the other ends of the two traction members 52 are rotatably connected to the two horizontal plates 41.

[0053] As the entire support plate 21 descends, the guide rod 31 drives the adjustment support plate 51 to rotate synchronously when it rotates. At this time, when the two ends of the adjustment support plate 51 are tilted, they push the traction members 52 connected to the two ends, so that the two traction members 52 drive their corresponding cross plates 41 to slide on the baffle 44 and gradually move away. At this time, the two spreading plates 42 in a slowly descending state will immediately move back to back and move toward the front and back sides of the support plate 21. When the two spreading plates 42 come into contact with the cigarette packaging paper, they will press down from the middle to the two sides to smooth it, so that the printed image area on the cigarette packaging paper can be squeezed and translated by the spreading plates 42, thereby simulating the cigarette packaging paper being squeezed by external objects after being packaged in the factory and generating moving friction, so that the image on the cigarette packaging paper can undergo a friction experiment;

[0054] Then, when the entire support plate 21 rises, the guide rod 31 reverses and drives the adjustment support plate 51 to rotate in the opposite direction by a certain angle. At this time, the two ends of the adjustment support plate 51 also tilt in the opposite direction and pull the traction members 52 at both ends, so that the two traction members 52 drive their corresponding cross plates 41 to slide on the baffle 44 and gradually approach each other, so that the two spreading plates 42 can rise and return to the initial position, so as to conduct a simulated contact experiment on the graphic area to be tested later on the cigarette packaging paper. As the two spreading plates 42 rise and approach, the graphic printing detector 11 on the spreading plate 42 will use the through slot 43 to detect the clarity of the graphic area on the cigarette packaging paper that is squeezed and rubbed by the spreading plate 42, so as to determine whether the graphic on the paper is blurred after being squeezed and rubbed, thereby realizing an automated cigarette packaging paper graphic printing process.

[0055] Secondly, in actual application, some cigarette packaging papers will have a certain curvature on their surface during the transportation and processing process. The two spreading plates 42 in the present invention can perform a rolling and flattening operation on the curved parts of the cigarette packaging paper after pressing down and translating. Combined with the translation of the cigarette packaging paper on the processing table 1, the surface of the entire cigarette packaging paper can be rolled and flattened multiple times, so that the curved parts of the cigarette packaging paper can be restored to a flat state, so as to facilitate subsequent processing of the cigarette packaging paper.

[0056] The processing table 1 is provided with a plurality of stoppers 12, which are symmetrically arranged in groups of two at the front and rear areas of the two spreading plates 42, and each stopper 12 is threadedly connected to the processing table 1 by a bolt;

[0057] The cigarette wrapping paper can be positioned by using a plurality of blocks 12 symmetrically arranged in groups of two. When the cigarette wrapping paper is conveyed to the processing table 1, the conveying equipment can be used to set the translation position of the cigarette wrapping paper, so that the cigarette wrapping paper can be translated between the blocks 12 arranged in groups of two. The blocks 12 limit the outer edges of the cigarette wrapping paper so that the cigarette wrapping paper will not tilt when squeezed by the spreading plate 42.

[0058] The invention also provides a device and method for detecting graphic printing on cigarette packaging paper. The method is implemented based on the method for using the above-mentioned device for detecting graphic printing on cigarette packaging paper. The method includes the following steps:

[0059] S1: The cigarette wrapping paper is conveyed onto the processing table 1, and a plurality of stoppers 12 symmetrically arranged in pairs are used to limit the position of the cigarette wrapping paper from both sides to prevent the paper from tilting or deviating.

[0060] S2: The driving motor 36 starts to drive the guide rod 31 and the two first guide wheels 32 to rotate slightly by a certain angle, and the transmission action of the transmission belt 35 drives the second guide wheel 33, the third guide wheel 34 and the corresponding sleeve 37 to rotate synchronously. The second guide wheel 33, the third guide wheel 34 and the corresponding sleeve 37 descend in a spiral shape on the guide rod 31, driving the support plate 21 and the two spreading plates 42 below to squeeze the cigarette packaging paper.

[0061] S3: When the guide rod 31 rotates, it will drive the adjustment support plate 51 to rotate synchronously. The two ends of the adjustment support plate 51 are tilted and push the two traction parts 52, so as to drive the two horizontal plates 41 and the spreading plate 42 to be pressed down and translated backwards to squeeze and translate the printed images on the cigarette packaging paper, so as to simulate the cigarette packaging paper being squeezed by external objects after being packaged in the box in the processing factory and generating moving friction.

[0062] S4: The driving motor 36 reverses to drive the guide rod 31 and the two first guide wheels 32 to reverse, and under the transmission action of the transmission belt 35, the second guide wheel 33 and the third guide wheel 34 and the corresponding sleeve 37 rise in a spiral on the guide rod 31, and drive the support plate 21 and the two spreading plates 42 below to separate from the squeezed cigarette packaging paper. During the rising and approaching process of the spreading plates 42, the graphic printing detector 11 can detect the clarity of the printed graphics on the cigarette packaging paper below through the through slot 43 to determine whether the graphics are blurred.

[0063] S5: By applying conveying equipment to carry out translational conveying of the cigarette packaging paper during processing, and combining with the repeated operation of the drive motor 36, the two spreading plates 42 can be used to perform multiple extrusion and translational friction on the surface of the cigarette packaging paper, so that the printed images on the entire cigarette packaging paper can be simulated by first performing an extrusion and friction experiment and then performing a clarity detection operation.

[0064] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
