Description

Technical Field

[0001] This invention relates to the field of self-adhesive label paper production technology, specifically to a visual inspection device for self-adhesive label paper production. Background Technology

[0002] Labels are an effective tool for individuals to check product quality. Therefore, after the label production is completed, the factory inspection of the label is particularly important. Visual inspection is a key link to ensure product quality. It is necessary to detect printing deviations, missing ink, stains and dimensional accuracy of the label pattern to prevent defective products from entering the market. Traditional inspection relies on manual labor, which is inefficient and prone to missed detections due to fatigue. Existing equipment often lacks a pre-cleaning mechanism. Dust and adhesive stains on the label surface can easily interfere with the inspection results, resulting in a high false detection rate. At the same time, after inspection, manual positioning and cutting of defective products are required, which leads to loose process connections and restricts production efficiency. As label printing develops towards high precision and large-scale production, the requirements for automation, accuracy and integration of inspection equipment have significantly increased.

[0003] Manual inspection is inefficient and has a high rate of missed detections; the lack of pre-cleaning leads to false detections due to dust and adhesive residue; manual cutting is required after inspection, resulting in a disjointed process; and the fixed position of the inspection camera makes it difficult to adapt to different label sizes, resulting in poor flexibility. Summary of the Invention

[0004] To achieve the above requirements, the present invention provides the following technical solution: A visual inspection device for self-adhesive label production includes a support base, a first bracket fixedly connected to the top of the support base, a guide opening on one side of the first bracket, a fixed end of a first electric telescopic rod fixedly connected to the bottom of the inner wall of the guide opening, a movable slider fixedly connected to the movable end of the first electric telescopic rod, a first motor fixedly connected to one side of the movable slider via a motor bracket, a drive shaft of the first motor passing through the movable slider and fixedly connected to a release roller, the movable slider being slidably connected to the inner wall of the guide opening, and a cleaning device fixedly connected to the top of the support base located on one side of the first bracket. A second bracket is fixedly connected to one side of the device. A tension roller is rotatably connected to one side of the second bracket. A third bracket is fixedly connected to the top of the support base located on one side of the second bracket. Multiple sets of the third brackets are evenly distributed on the top of the support base. A first electric guide rail is fixedly connected to one side of the third bracket. The fixed end of a second electric telescopic rod is fixedly connected to the side of the slider inside the first electric guide rail. A pressing pad is fixedly connected to the movable end of the second electric telescopic rod. A cutting opening is provided at the center of the multiple sets of third brackets on the top of the support base. A cutting device is fixedly connected to one side of the inner wall of the cutting opening. A winding mechanism is fixedly connected to the top of the support base located on one side of the third bracket.

[0005] Preferably, two sets of the first bracket are symmetrically distributed on the support base, and two sets of the second bracket are symmetrically distributed on the support base. The first electric telescopic rod in the guide port of the first bracket is activated to push the moving slider to slide up and down along the inner wall of the guide port, adjust the height of the release roller, and ensure that the label paper feeding path is stable. Then, the first motor on one side of the moving slider is activated, and its drive shaft drives the release roller to rotate, gradually releasing the label paper roll. The released label paper first passes through the cleaning device at the top of the support base to avoid stains affecting the subsequent detection accuracy.

[0006] Preferably, the cleaning device includes a cleaning base, a fourth bracket fixedly connected to the top of the cleaning base, a pulley transmission mechanism fixedly connected to one side of the fourth bracket, the input end of the pulley transmission mechanism passing through the fourth bracket and fixedly connected to a first sweeping roller, a sweeping brush head fixedly connected to one side of the first sweeping roller, two sets of the first sweeping rollers symmetrically distributed on one side of the fourth bracket, multiple sets of the sweeping brush heads evenly distributed on the first sweeping rollers, a fixed end of a third electric telescopic rod fixedly connected to one side of the fourth bracket, the third electric telescopic rod symmetrically distributed on one side of the fourth bracket, a cleaning mechanism fixedly connected to the movable end of the third electric telescopic rod, and a detection device fixedly connected to the top of the cleaning base located on one side of the third electric telescopic rod.

[0007] Preferably, the bottom of the cleaning base is fixedly connected to the top of the support base, and the fourth bracket is provided in two sets and symmetrically distributed on the cleaning base. When the pulley transmission mechanism is activated, its power is transmitted through the input end to the two sets of symmetrically distributed first cleaning rollers, which drive the rollers to rotate synchronously and sweep the upper and lower surfaces of the label paper.

[0008] Preferably, the cleaning mechanism includes a cleaning housing, a scraper blade is fixedly connected to the bottom of the inner wall of the cleaning housing, multiple sets of scraper blades are provided and evenly distributed inside the cleaning housing, a first air outlet is opened in the part of the bottom of the inner wall of the cleaning housing between adjacent scraper blades, a connecting box is fixedly connected to the bottom of the cleaning housing, the top of the connecting box is connected to the cleaning housing, the connecting box is connected to the air inlet of the filter canister through a pipe, and the air outlet of the filter canister is connected to the air inlet of the first air pump through a pipe.

[0009] Preferably, the first air pump is fixedly connected to the fourth bracket via a bracket, and one side of the cleaning housing is fixedly connected to the movable end of the third electric telescopic rod. When the third electric telescopic rod is activated to push the cleaning mechanism closer to the first cleaning roller, multiple sets of scraping blades at the bottom of the inner wall of the cleaning housing first come into contact with the surface of the cleaning brush head. As the first cleaning roller continues to rotate, the first air pump is activated, creating a negative pressure environment inside the connecting box and the cleaning housing. The impurities peeled off by the scraping blades are adsorbed by the negative pressure and enter the connecting box through the first air outlet between adjacent scraping blades at the bottom of the cleaning housing, and then transported to the filter tank through a pipeline.

[0010] Preferably, the detection device includes a detection bracket. A second motor is fixedly connected to one side of the detection bracket via a bracket. The drive shaft of the second motor passes through the detection bracket and is fixedly connected to a first rotating roller. The portion of the inner wall of the detection bracket above the first rotating roller is rotatably connected to a second rotating roller via a rotating bearing. A fourth electric telescopic rod is fixedly connected to the top of the detection bracket. A camera housing is fixedly connected to the movable end of the fourth electric telescopic rod. A detection camera is fixedly connected to the bottom of the camera housing. Multiple detection cameras are provided and evenly distributed at the bottom of the camera housing. A fifth electric telescopic rod is fixedly connected to one side of the camera housing. A cleaning strip is fixedly connected to the movable end of the fifth electric telescopic rod via a connecting bracket. A lighting mechanism is fixedly connected to the top of the inner wall of the detection bracket on one side of the fourth electric telescopic rod.

[0011] Preferably, the bottom of the detection bracket is fixedly connected to the top of the cleaning base. Two sets of the fourth electric telescopic rods are provided and symmetrically distributed on the detection bracket. When the second motor on one side of the detection bracket is started, its drive shaft drives the first rotating roller to rotate. Together with the second rotating roller above, the label paper is smoothly transported to the detection area. According to the thickness of the label paper and the detection requirements, the two sets of symmetrically distributed fourth electric telescopic rods are adjusted, and their movable ends push the camera box to move up and down, so that multiple sets of evenly distributed detection cameras at the bottom are aligned with the surface of the label paper.

[0012] Preferably, the cutting device includes a cross guide rail, with an electric rotary table fixedly connected to the top of the slider inside the cross guide rail. The top of the electric rotary table is fixedly connected to the fixed ends of a sixth and a seventh electric telescopic rod, respectively. The tops of the sixth and seventh electric telescopic rods are respectively fixedly connected to a first cutting block and a second cutting block. One side of the cross guide rail is fixedly connected to the inner wall of the cutting opening. The slider inside the cross guide rail drives the electric rotary table to move rapidly, moving the first and second cutting blocks to the cutting area corresponding to the defective label. If label defects need to be cut, the sixth electric telescopic rod is extended to push the first cutting block against the label paper surface. Combined with the linear movement of the cross guide rail, the defect is cut off. When cutting different labels, the electric rotary table is activated to adjust the angle of the cutting blocks, while the seventh electric telescopic rod drives the second cutting block to cut the label paper.

[0013] This invention provides a visual inspection device for the production of self-adhesive label paper. It has the following beneficial effects:

[0014] 1. The visual inspection device for self-adhesive label production first adjusts the first electric telescopic rod according to the label roll diameter, pushes the moving slider to adjust the height of the release roller, and ensures a smooth feeding path; the first motor is started to drive the release roller to rotate and unwind, and the label paper passes through the cleaning device to remove surface impurities and the tension roller to keep it flat and wrinkle-free. When a damaged or missing label is detected, the label paper is conveyed to the third support, the first electric guide rail drives the second electric telescopic rod to move and position, the telescopic rod extends to fix the paper with the pressure pad, and then the cutting device is started to cut the damaged area along the cutting edge, and the waste falls down for easy collection; the qualified labels after cutting are simultaneously wound up by the winding mechanism.

[0015] 2. In this visual inspection device for self-adhesive label production, when the label paper is conveyed to the cleaning device, the pulley transmission mechanism is activated, and the power is transmitted to two sets of symmetrical first cleaning rollers and drives them to rotate. Multiple sets of cleaning brush heads on the side of the rollers rotate synchronously, sweeping the upper and lower surfaces of the label paper in all directions, efficiently removing dust, fibers and other impurities, and avoiding affecting the accuracy of subsequent visual inspection. As cleaning continues, impurities are easily attached to the brush heads. At this time, the third electric telescopic rod on the fourth bracket is activated to push the cleaning mechanism to fit against the surface of the cleaning brush head. In conjunction with the rotation of the first cleaning roller, impurities between the brush filaments are scraped or adsorbed, realizing the self-cleaning of the brush head. This solves the problem of brush heads being easily dirty and clogged in traditional devices and requiring frequent manual cleaning, ensuring efficient subsequent cleaning. After the brush head is cleaned, the detection device on the top of the cleaning base checks the removal effect of impurities on the surface of the label paper, which can also indirectly determine the cleanliness of the brush head.

[0016] 3. In this visual inspection device for self-adhesive label production, after the third electric telescopic rod is activated to push the cleaning mechanism close to the first cleaning roller, multiple sets of scraping blades inside the cleaning housing first contact the cleaning brush head. As the first cleaning roller rotates, the scraping blades physically scrape off the dust and fibers between the brush bristles, initially cleaning the brush head and preventing the accumulation of impurities from affecting subsequent cleaning. Simultaneously, the first air pump is activated, creating a negative pressure inside the connecting box and the cleaning housing. The stripped impurities enter the connecting box through the first air outlet at the bottom of the cleaning housing and are then transported to the filter tank for interception and filtration to prevent impurities from drifting and causing secondary pollution. The purified air is discharged by the first air pump.

[0017] 4. This visual inspection device for self-adhesive label production ensures the label surface is initially clean before entering the inspection device: The second motor on one side of the inspection bracket is activated, its drive shaft rotates the first rotating roller, which, together with the second rotating roller above, smoothly conveys the label to the inspection area, preventing conveying deviation from affecting the inspection. Based on the label thickness and inspection requirements, two sets of symmetrical fourth electric telescopic rods are adjusted to move the camera housing up and down, ensuring that multiple inspection cameras at the bottom are precisely aligned with the label surface. Simultaneously, the lighting mechanism is activated to provide sufficient light, ensuring the cameras clearly capture defects, reducing missed detections caused by insufficient light and fixed lens positions in traditional inspection methods. If dust adheres to the lens and affects imaging, the fifth electric telescopic rod is activated, moving the cleaning strip along the lens to remove stains.

[0018] 5. This visual inspection device for self-adhesive label production uses a slider inside a cross guide rail to drive an electric rotary table to move rapidly, moving the first and second cutting blocks to the cutting area corresponding to the defective label. If label defects need to be cut, the sixth electric telescopic rod is adjusted to extend, pushing the first cutting block to fit against the label surface. Combined with the linear movement of the cross guide rail, the defect is removed. When cutting different labels, the electric rotary table is activated to adjust the angle of the cutting blocks, while the seventh electric telescopic rod drives the second cutting block to cut the label paper, achieving targeted cutting of local defects and avoiding material waste caused by overall cutting. It can efficiently remove defective labels. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] For the first embodiment, please refer to... Figures 1-2This invention provides a technical solution that improves the continuity and processing accuracy of self-adhesive label production: a visual inspection device for self-adhesive label production includes a support base 1, a first bracket 2 fixedly connected to the top of the support base 1, a guide opening 3 on one side of the first bracket 2, a fixed end of a first electric telescopic rod 4 fixedly connected to the bottom of the inner wall of the guide opening 3, a movable slider 5 fixedly connected to the movable end of the first electric telescopic rod 4, a first motor 6 fixedly connected to one side of the movable slider 5 via a motor bracket, a drive shaft of the first motor 6 passing through the movable slider 5 and fixedly connected to a release roller 7, the movable slider 5 slidingly connected to the inner wall of the guide opening 3, and a cleaning device 8 fixedly connected to the top of the support base 1 located on one side of the first bracket 2. A second bracket 9 is fixedly connected to the side of the support base 1. A tension roller 10 is rotatably connected to one side of the second bracket 9. A third bracket 11 is fixedly connected to the top of the support base 1 located on one side of the second bracket 9. Multiple sets of third brackets 11 are provided and evenly distributed on the top of the support base 1. A first electric guide rail 12 is fixedly connected to one side of the third bracket 11. The fixed end of the second electric telescopic rod 13 is fixedly connected to the side of the slider inside the first electric guide rail 12. A pressing pad 14 is fixedly connected to the movable end of the second electric telescopic rod 13. A cutting opening 15 is opened at the center of the multiple sets of third brackets 11 on the top of the support base 1. A cutting device 16 is fixedly connected to one side of the inner wall of the cutting opening 15. A winding mechanism 17 is fixedly connected to the top of the support base 1 located on one side of the third bracket 11.

[0031] In use, first, according to the roll diameter of the self-adhesive label paper to be processed, start the first electric telescopic rod 4 inside the guide port 3 of the first bracket 2, push the moving slider 5 to slide up and down along the inner wall of the guide port, and adjust the height of the release roller 7 to ensure a smooth feeding path for the label paper. Then, start the first motor 6 on one side of the moving slider, and its drive shaft drives the release roller to rotate, gradually releasing the roll of label paper. The released label paper first passes through the cleaning device 8 on the top of the support base 1 to remove surface dust and impurities, so as to avoid stains affecting the subsequent detection accuracy. Then, it passes through the tension roller 10 on the second bracket 9 to keep the paper flat and wrinkle-free. During the detection process, if a label is detected to be damaged or missing, the label paper is conveyed to multiple sets of third brackets. Between the frames 11, the first electric guide rail 12 is activated, and its slider drives the second electric telescopic rod 13 to move to the designated position. Then the telescopic rod extends, pushing the pressing pad 14 to press and fix the label paper to the surface of the support base, preventing the paper from shifting during cutting. After positioning, the cutting device 16 located in the cutting opening 15 is activated to cut the label paper, removing the damaged areas. Waste material falls below the cutting opening 15 for easy collection and disposal. The cut label paper is simultaneously wound up by the winding mechanism 17. Through the coordinated cooperation of various components, the entire device effectively improves the continuity and processing accuracy of self-adhesive label paper production, adapts to the production needs of different specification labels, and reduces the amount of defective products.

[0032] The first bracket 2 is provided in two sets and symmetrically distributed on the support base 1, and the second bracket 9 is provided in two sets and symmetrically distributed on the support base 1.

[0033] For the second embodiment, please refer to... Figures 1-3 Based on the first embodiment, the present invention provides a technical solution that solves the problem of stains on labels and avoids impurities affecting the accuracy of subsequent visual inspection: the cleaning device 8 includes a cleaning base 81, a fourth bracket 82 is fixedly connected to the top of the cleaning base 81, a pulley transmission mechanism 83 is fixedly connected to one side of the fourth bracket 82 through the bracket, the input end of the pulley transmission mechanism 83 passes through the fourth bracket 82 and is fixedly connected to a first cleaning roller 84, a cleaning brush head 85 is fixedly connected to one side of the first cleaning roller 84, two sets of the first cleaning roller 84 are provided and symmetrically distributed on one side of the fourth bracket 82, multiple sets of cleaning brush heads 85 are provided and evenly distributed on the first cleaning roller 84, a fixed end of a third electric telescopic rod 86 is fixedly connected to one side of the fourth bracket 82, the third electric telescopic rod 86 is symmetrically distributed on one side of the fourth bracket 82, a cleaning mechanism 87 is fixedly connected to the movable end of the third electric telescopic rod 86, and a detection device 88 is fixedly connected to the top of the cleaning base 81 located on one side of the third electric telescopic rod 86.

[0034] The bottom of the cleaning base 81 is fixedly connected to the top of the support base 1, and two sets of the fourth bracket 82 are provided and symmetrically distributed on the cleaning base 81.

[0035] In use, during the feeding process of the first embodiment, when the label paper is conveyed to the cleaning device 8, the pulley transmission mechanism 83 is activated. Its power is transmitted through the input end to two symmetrically distributed first cleaning rollers 84, causing the rollers to rotate synchronously. Multiple evenly distributed cleaning brush heads 85 on the sides of the rollers rotate accordingly, performing all-around sweeping of the upper and lower surfaces of the label paper, efficiently removing dust, fibers, and other impurities attached to the surface, preventing impurities from affecting the accuracy of subsequent visual inspection. As the cleaning operation continues, impurities easily adhere to the surface of the cleaning brush heads 85, affecting the subsequent cleaning effect. At this time, the third electric telescopic rod 86 on one side of the fourth bracket 82 is activated. Its movable end pushes the cleaning mechanism 87 closer to the first cleaning rollers 84 until it adheres to the surface of the cleaning brush heads 85. With the continuous rotation of the first cleaning roller, the cleaning mechanism cleans the brush head, scraping away or adsorbing impurities entangled between the brush bristles, achieving self-cleaning of the brush head and ensuring that subsequent cleaning remains highly efficient. This solves the problem of brush heads easily getting dirty and clogged in traditional cleaning devices, requiring frequent manual disassembly and cleaning. After the brush head is cleaned, the detection device 88 on the top of the cleaning base 81 can perform spot checks on the surface of the cleaned label paper to confirm the impurity removal effect. At the same time, it can also indirectly determine whether the self-cleaning meets the standard by detecting the cleanliness of the brush head. Two sets of symmetrical fourth supports 82 provide stable support for each component, and in conjunction with the feeding rhythm of the first embodiment, continuous operation is achieved, ensuring the cleanliness of the label paper surface. The self-cleaning of the brush head extends the service life of the device and improves the accuracy of subsequent detection.

[0036] Third embodiment, please refer to Figures 1-5 Based on the second embodiment, the present invention provides a technical solution to improve the cleanliness and service life of the cleaning brush head, ensuring continuous and efficient cleaning of self-adhesive labels and ensuring the accuracy of subsequent visual inspection: The cleaning mechanism 87 includes a cleaning shell 871, a scraper 872 is fixedly connected to the bottom of the inner wall of the cleaning shell 871, multiple sets of scraper 872 are provided and evenly distributed inside the cleaning shell 871, a first air outlet 873 is opened on the bottom of the inner wall of the cleaning shell 871 between adjacent scraper 872, a connecting box 874 is fixedly connected to the bottom of the cleaning shell 871, the top of the connecting box 874 is connected to the cleaning shell 871, the connecting box 874 is connected to the air inlet of the filter canister 875 through a pipe, and the air outlet of the filter canister 875 is connected to the air inlet of the first air pump 876 through a pipe.

[0037] The first air pump 876 is fixedly connected to the fourth bracket 82 via a bracket, and one side of the cleaning housing 871 is fixedly connected to the movable end of the third electric telescopic rod 86.

[0038] In use, in the second embodiment, after the third electric telescopic rod 86 is activated to push the cleaning mechanism 87 close to the first sweeping roller 84, multiple sets of scraping blades 872 at the bottom of the inner wall of the cleaning housing 871 first come into contact with the surface of the cleaning brush head 85. As the first sweeping roller 84 continues to rotate, the scraping blades remove dust, fibers, and other impurities entangled between the brush bristles through physical scraping, initially completing the cleaning of the brush head and preventing the accumulation of impurities from affecting subsequent cleaning efficiency. Simultaneously, the first air pump 876 is activated, creating a negative pressure environment inside the connecting housing 874 and the cleaning housing 871. The impurities removed by the scraping blades are adsorbed under the negative pressure and pass through the first air pump between adjacent scraping blades at the bottom of the cleaning housing. Air enters the connecting housing through the outlet 873 and is then transported to the filter canister 875 through a pipeline. The filter canister intercepts and filters impurities to prevent them from circulating with the airflow and causing secondary pollution. The purified air is discharged by the first air pump. Throughout the process, the cleaning shell 871 provides stable protection for the scraper blade and the airflow channel. The third electric telescopic rod can finely adjust the position of the cleaning mechanism according to the wear of the brush head to ensure that the scraper blade always fits the surface of the brush head. This design solves the problem that traditional brush head cleaning relies solely on physical scraping, and that impurities are easily left behind or scattered. It improves the cleanliness and service life of the cleaning brush head, provides a guarantee for the continuous and efficient cleaning of self-adhesive labels, and ensures the accuracy of subsequent visual inspection.

[0039] For the fourth embodiment, please refer to [link / reference]. Figures 1-7 Based on the third embodiment, the present invention provides a technical solution to reduce the problem of missed detection caused by insufficient light and fixed lens position in traditional detection: the detection device 88 includes a detection bracket 881, a second motor 882 is fixedly connected to one side of the detection bracket 881 via a bracket, the drive shaft of the second motor 882 passes through the detection bracket 881 and is fixedly connected to a first rotating roller 883, the part of the inner wall of the detection bracket 881 above the first rotating roller 883 is rotatably connected to a second rotating roller 884 via a rotating bearing, and a fourth motor is passed through and fixedly connected to the top of the detection bracket 881. The fixed end of the fourth electric telescopic rod 885 is fixedly connected to the movable end of the fourth electric telescopic rod 885. A detection camera 887 is fixedly connected to the bottom of the camera box 886. Multiple detection cameras 887 are provided and evenly distributed at the bottom of the camera box 886. The fixed end of the fifth electric telescopic rod 888 is fixedly connected to one side of the camera box 886. A cleaning strip 889 is fixedly connected to the movable end of the fifth electric telescopic rod 888 through a connecting bracket. A lighting mechanism 8810 is fixedly connected to the top part of the inner wall of the detection bracket 881 located on one side of the fourth electric telescopic rod 885.

[0040] The bottom of the inspection bracket 881 is fixedly connected to the top of the cleaning base 81, and two sets of the fourth electric telescopic rod 885 are provided and symmetrically distributed on the inspection bracket 881.

[0041] In use, after the cleaning brush head is cleaned and the label paper surface is initially cleaned in the third embodiment, the label paper enters the detection device 88: the second motor 882 on one side of the detection bracket 881 is activated, and its drive shaft drives the first rotating roller 883 to rotate. This, in conjunction with the second rotating roller 884 above, smoothly conveys the label paper to the detection area. Based on the label paper thickness and detection requirements, the two symmetrically distributed fourth electric telescopic rods 885 are adjusted, and their movable ends push the camera housing 886 up and down, aligning the multiple evenly distributed detection cameras 887 at the bottom with the label paper surface. Simultaneously, the lighting mechanism 8810 on the top of the inner wall of the detection bracket is activated to provide sufficient light to ensure... The camera clearly captures imperfections on the label surface, reducing the problem of missed detection caused by insufficient light and fixed lens position in traditional inspection. If dust adheres to the camera lens during the inspection process, affecting the image quality, the fifth electric telescopic rod 888 on one side of the camera housing is activated. Its movable end drives the cleaning strip 889 to move along the lens surface, quickly removing lens stains and ensuring the continuity and accuracy of the inspection. Throughout the process, the coordinated conveying of the first and second rotating rollers, the adjustable camera height, and the supplementary lighting ensure the inspection quality of the self-adhesive label. The lens self-cleaning function reduces equipment downtime for maintenance, further improving the overall efficiency of label production.

[0042] For the fifth embodiment, please refer to... Figures 1-9 Based on the fourth embodiment, the present invention provides a technical solution that solves the problem of cutting out damaged or incomplete areas of label paper: the cutting device 16 includes a cross guide rail 161, an electric rotating table 162 is fixedly connected to the top of the slider inside the cross guide rail 161, the fixed ends of the sixth electric telescopic rod 163 and the seventh electric telescopic rod 164 are fixedly connected to the top of the electric rotating table 162 respectively, the first cutting block 165 and the second cutting block 166 are fixedly connected to the top of the sixth electric telescopic rod 163 and the seventh electric telescopic rod 164 respectively, and one side of the cross guide rail 161 is fixedly connected to the inner wall of the cutting opening 15.

[0043] In use, after the label paper defect detection and defect location are marked in the fourth embodiment, the cutting device 16 starts operation: First, according to the defect coordinates fed back by the detection system, the slider inside the cross guide rail 161 drives the electric rotary table 162 to move quickly, moving the first cutting block 165 and the second cutting block 166 to the cutting area corresponding to the defective label. If the label defect needs to be cut, the sixth electric telescopic rod 163 is adjusted to extend, pushing the first cutting block 165 to fit against the label paper surface. With the linear movement of the cross guide rail, the defect is cut off. When cutting different labels, the electric rotary table 162 is started to adjust the angle of the cutting block. At the same time, the seventh electric telescopic rod 164 drives the second cutting block 166 to cut the label paper, realizing targeted cutting of local defects, avoiding material waste caused by overall cutting, efficiently cutting defective labels, and flexibly adjusting the cutting method according to the defect shape, improving the yield and material utilization of label paper processing, adapting to the cutting needs of different specifications of labels, and adjusting the number of cutting blades on the electric rotary table 162 to adapt to the cutting of different labels.

[0044] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
