Description

Technical Field

[0001] This application relates to the field of self-adhesive label printing, and more specifically, to a digital printing device for QR code self-adhesive labels. Background Technology

[0002] With the rapid development of the Internet of Things, anti-counterfeiting traceability, and mobile marketing, the demand for QR code self-adhesive labels in the logistics, retail, pharmaceutical, electronics, and daily chemical industries has exploded. Traditional QR code label production typically employs a two-stage process of "offline printing + offline lamination": first, variable QR codes and graphics are printed on a digital printing press or flexographic press; then, the semi-finished product is transferred to a laminating machine for protective film application. This model has the following prominent problems:

[0003] Printing and lamination are done on two separate machines, requiring manual transfer, secondary winding, and secondary alignment in between. The average roll change time is 5-8 minutes, and the overall production capacity is more than 30% lower than that of integrated equipment. At the same time, repeated handling can easily cause scratches on QR codes and smudges on graphics, resulting in a high scrap rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a digital printing device for QR code self-adhesive labels, solving the problems mentioned in the background section. To achieve the above objectives, this utility model employs the following technical solution:

[0005] A digital printing device for QR code self-adhesive labels includes two fixed plates connected by four connecting rods. Guide roller one and guide roller two are connected between the two fixed plates and located on the left side of the fixed plates.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] See Figures 1-3 This embodiment provides a digital printing device for QR code self-adhesive labels, including two fixed plates 1 connected by four connecting rods 2. A guide roller 3 and a guide roller 4 are respectively connected between the two fixed plates 1 and located on the left side of the fixed plates 1. A support platform 6 is fixedly connected between the two fixed plates 1, and a printer 5 is mounted above the support platform 6 and connected between the fixed plates 1. Self-adhesive stickers 7 are wound around the guide rollers 3 and 4, and the self-adhesive stickers 7 pass through the printer 5 and the support platform 6, moving to the right. A guide roller 3 11 is installed between the two fixed plates 1, and a protective film 8 is wound around the outer wall of the guide roller 3 11. A bonding mechanism 9 is provided between the two fixed plates 1 to assist in bonding the protective film 8 to the self-adhesive stickers 7. The bonding mechanism 9 includes:

[0026] Two fixing blocks 903 are set between two fixing plates 1, and a roller 901 is rotatably connected between the two fixing blocks 903 and located on both sides of the two fixing blocks 903, and is attached to the protective film 8 and the self-adhesive sticker 7.

[0027] A connecting plate 904 is fixedly connected between the two fixed plates 1, and an adjusting plate 905 is fixedly connected between the two fixed blocks 903. A screw 907 is rotatably connected to the top of the adjusting plate 905 through a bearing, and the screw 907 moves through the connecting plate 904 and extends upward.

[0028] Two sliding rods 906 are fixedly connected to the top of the adjusting plate 905 and are located on the front and rear sides of the screw 907. A spring 908 is sleeved on the outer wall of the screw 907, and the two ends of the spring 908 are connected between the connecting plate 904 and the adjusting plate 905.

[0029] In practical use, the above-mentioned equipment works by unwinding the self-adhesive label paper to be printed around the outer walls of the guide rollers 1-3 and 2-4 of the external unwinding device, then winding it over the support platform 6, and then passing it between the support roller 902 and the roller 901. At this time, the information to be printed is printed onto the surface of the self-adhesive label 7 by the printer 5 through the control device. Then, the protective film 8 is unwound by the external unwinding device, guided by the guide roller 3-11, and passes between the support roller 902 and the roller 901, covering the self-adhesive label 7 for lamination. The height of the roller 901 from the support roller 902 is adjusted according to the thickness of the self-adhesive label 7 and the protective film 8. At this time, by rotating the screw 907 and under the limit of the slide rod 906, the adjusting plate 905 can be moved up and down, thereby driving the fixed block 903 to move up and down, and at the same time driving the roller 901 to move up and down, so as to adapt to the compression and lamination of self-adhesive labels 7 and protective films 8 of different thicknesses, thereby improving the firmness of the lamination.

[0030] Example 2

[0031] See Figures 1-3 Based on Embodiment 1, a pressing mechanism 10 is provided below the adjusting plate 905. The pressing mechanism 10 includes:

[0032] The pressure plate 101 is located at the bottom of the adjusting plate 905 and is attached to the top of the protective film 8. Two sliding columns 104 are fixedly connected to the top of the pressure plate 101 and the sliding columns 104 move through the adjusting plate 905 upward. A second spring 105 is sleeved on the outer wall of the sliding column 104. The two ends of the second spring 105 are fixedly connected to the adjusting plate 905 and the pressure plate 101 respectively, and are used to push the pressure plate 101 downward.

[0033] Two T-shaped blocks 102 are fixedly connected to the top of the pressure plate 101, and multiple arc-shaped levers 103 are fixedly connected to the outer wall of the roller 901, with the arc-shaped levers 103 abutting against the T-shaped blocks 102.

[0034] One side of the T-shaped block 102 is arc-shaped and fits against the outer wall of the arc-shaped lever block 103. Multiple support rollers 902 are installed between the two fixed plates 1 and located below the roller 901. A guide roller 12 is also installed between the two fixed plates 1 to guide the self-adhesive sticker 7 after lamination.

[0035] In practical use, when the roller 901 rotates, the rotation of the left roller 901 will drive the arc-shaped lever 103 to rotate and push the T-shaped block 102 to move upward, thereby driving the pressure plate 101 to move upward and pushing the slide column 104 to move upward and compress the second spring 105. At the same time, after the arc-shaped lever 103 disengages from the T-shaped block 102, the pressure plate 101 is pushed downward by the second spring 105 and drives the slide column 104 to move downward. This causes the pressure plate 101 to move downward and approach the support roller 902, compressing the gap between the protective film 8 and the self-adhesive sticker 7 and the support roller 902. However, the protective film 8 and the self-adhesive sticker 7 can still continue to slide relative to the support roller 902 and the pressure plate 101, thereby further improving the adhesion of the protective film 8 to the self-adhesive sticker 7 and improving its bonding effect.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
