Technical Field

[0001] The utility model relates to the technical field of anti-counterfeiting coding, in particular to an anti-counterfeiting coding device for a packaging bag. Background Art

[0002] With the development of modern logistics and e-commerce, demand for packaging bags, a crucial component of product packaging and transportation, has increased significantly. However, the prevalence of counterfeit and inferior products in the market has caused significant economic losses and reputational damage to consumers and manufacturers. To prevent the proliferation of counterfeit and inferior products, anti-counterfeiting coding on packaging bags has become a crucial technical measure.

[0003] In the existing technology, most of the products are sealed in packaging bags first, and then the bags of products are placed one by one on a horizontal conveyor on a marking machine, and then anti-counterfeiting codes are marked by a laser marking machine. After completion, the products are stored.

[0004] When this type of device is in use, during the loading process, the staff will place the packaging bag at one end of the conveyor belt for transmission. If the objects are not placed carefully and the position is tilted, the pattern position will be offset during marking. During this period, the staff will need to straighten and correct it, resulting in low marking efficiency. If missed inspections are made, it will also affect the reliability of the anti-counterfeiting effect, which needs to be improved. Utility Model Content

[0026] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0027] Reference Figures 1 to 4, which is an embodiment of the utility model, provides an anti-counterfeiting coding device for a packaging bag, including a laser marking mechanism 100 and a correction mechanism 200;

[0028] The laser marking mechanism 100 includes a laser generator 101 and a galvanometer 102 used in conjunction with each other. The galvanometer 102 is arranged at the end of the laser generator 101, and a horizontal conveyor 103 is arranged below the galvanometer 102; the horizontal conveyor 103 includes a transmission belt 1031, a conveying roller 1032 and a motor 1033, the transmission belt 1031 is arranged on the conveying roller 1032, and the conveying roller 1032 is connected to the motor 1033.

[0029] The correcting mechanism 200 includes a swinging oblique rod 201, which is arranged on the left and right sides of the horizontal conveyor 103. One end of the swinging oblique rod 201 is fixedly connected to a drive shaft 202, and the drive shaft 202 is rotatably connected to a coding limit plate 203; the swinging oblique rod 201 is arranged in an "eight" shape on the feeding side of the coding limit plate 203, and there is a gap between the coding limit plate 203 and the bottom of the swinging oblique rod 201 and the horizontal conveyor 103; the coding limit plate 203 is arranged directly below the galvanometer 102, and two groups of coding limit plates 203 are provided, and the two groups of coding limit plates 203 are respectively arranged on both sides of the horizontal conveyor 103.

[0030] The top end of the driving shaft 202 passes through the coding limit plate 203 and is connected to the driven gear 204. The driven gear 204 includes a first gear 2041 and a second gear 2042. One side of the first gear 2041 is meshed with the driving gear 205 for transmission connection. The driving gear 205 is connected to a synchronous shaft. The synchronous shaft and the second gear 2042 are both connected to a synchronous wheel 208 on the driving shaft 202. The two sets of synchronous wheels 208 are mechanically connected by a synchronous belt 207; the driving gear 205 is connected to a power mechanism 206 for controlling the rotation of the driving gear 205. The power mechanism 206 includes an electric telescopic rod 2061 and a telescopic rack group 2062. The telescopic rack group 2062 is meshed with the second gear 2042 for transmission connection, and the rear end of the telescopic rack group 2062 is connected to the telescopic end of the electric telescopic rod 2061.

[0031] In this embodiment, when in use, the operator starts the motor 1033 and the electric telescopic rod 2061, and then places the packaging bags to be printed with anti-counterfeiting codes one by one on the horizontal conveyor 103. As the motor 1033 drives the transmission belt 1031 through the transmission roller 1032, the packaging bags are driven to the correction mechanism 200.

[0032] At this time, the electric telescopic rod 2061 pushes the telescopic rack plate 2062 to reciprocate and extend, and the telescopic rack plate 2062 is connected to the second gear 2042 through meshing transmission, so that the second gear 2042 is driven to rotate forward and reverse. Since the second gear 2042 is mechanically connected to the two sets of synchronous wheels 208 on the driving gear 205 through the synchronous belt 207, the driving gear 205 rotates synchronously with the second gear 2042. Since the driving gear 205 is connected to the first gear 2041 through meshing transmission, the first gear 2041 and the second gear 2042 rotate in opposite directions, and then the two sets of swinging inclined rods 201 are controlled by the driving shaft 202 to move closer to or away from each other on the horizontal conveyor 103;

[0033] Specifically, when the two sets of swinging inclined rods 201 approach each other, the passing packaging bags are concentrated in the middle of the horizontal conveyor 103, and then move to the bottom of the galvanometer 102 after passing the coding limit plate 203. The high-energy laser beam is emitted by the laser generator 101, and the required anti-counterfeiting pattern is realized on the surface of the marked packaging bag through the galvanometer 102.

[0034] When the two groups of swinging oblique rods 201 move away from each other, space for the next packaging bag to enter is left between the two groups of swinging oblique rods 201, waiting for the next deviation-correcting action.

[0035] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
