Description

Technical Field

[0001] This utility model relates to the field of cigarette box printing technology, specifically to a device for automatic QR code printing and detection. Background Technology

[0002] Spraying QR codes onto cigarette boxes is an important measure for the digital and intelligent transformation of the tobacco industry. Its core purpose is to improve supply chain management efficiency, enhance anti-counterfeiting capabilities, optimize consumer experience, and meet regulatory compliance requirements. The QR codes are formed on the surface of the cigarette boxes using a coding machine.

[0003] In traditional technology, inkjet printing is arranged in rows and columns, or in other special arrangements such as angled arrangements. During operation, the printheads are fixedly installed according to the required arrangement, and the product moves at a uniform speed. The printing speed is generally equivalent to the product conveyor speed. In the current production process, the number of printheads required for a product printout is equal to the number of rows of inkjet printing. As the required number of rows increases, more printheads need to be added or the printhead positions need to be adjusted. However, printheads are expensive, and adding printheads will increase costs accordingly. Currently, the printhead positions on inkjet printing mechanisms are usually fixed, and they can only print QR codes in one direction, which cannot meet production needs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic QR code printing and detection device, which aims to solve the problem that the position of the printhead on the inkjet mechanism in the existing technology is usually fixed, and it can only print the mark in one direction, which cannot meet the production needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A QR code automatic printing and inspection device includes a machine body. An ascending seat is fixedly connected inside the machine body. Mounting seats are symmetrically fixedly connected to the top of the ascending seat. A limiting rod is fixedly connected between the mounting seats. A receiving platform is slidably connected to the outside of the limiting rod. A disc is fixedly connected to the top of the receiving platform. A first motor is fixedly connected to the middle of the top of the disc. A sleeve is fixedly connected to the output end of the first motor. An installation rod is rotatably connected inside the sleeve. A material box is fixedly connected to one end of the installation rod. A printhead is fixedly connected to one end of the material box.

[0006] As a preferred embodiment of this utility model, the left end of the machine body is rotatably connected to an unwinding roller, the right end of the machine body is fixedly connected to a bracket, and the inside of the bracket is rotatably connected to two sets of conveying rollers, one end of each set of conveying rollers is fixedly connected to a second motor.

[0007] As a preferred embodiment of this utility model, a support frame is fixedly connected to the edge of the top of the disc, and an electric telescopic rod is fixedly connected to the top of the disc and between the two sets of support frames. An annular disc is fixedly connected to the output end of the electric telescopic rod, and the support frame is used to support the annular disc.

[0008] As a preferred embodiment of this utility model, the annular disk has an annular groove inside, one end of the mounting rod is fixedly connected to a connecting rod, the connecting rod has an L-shaped structure design, one end of the connecting rod is fixedly connected to a fixing ball, and the fixing ball is slidably connected inside the annular groove.

[0009] As a preferred embodiment of this utility model, a lead screw is rotatably connected to the middle of the mounting base. The lead screw passes through the interior of the receiving platform and is threadedly connected to the receiving platform. A third motor is fixedly connected to one end of the lead screw.

After the fixed ball is subjected to the force, it is transmitted to the connecting rod, which then enables the mounting rod to rotate inside the sleeve, thereby raising the nozzle and completing the adjustment of the nozzle's up and down angle.

[0013] 2. In this utility model, the detection camera rotates inside the U-shaped frame to scan and monitor the surface of the cigarette cardboard. When a code is missed, an alarm is directly triggered on the display. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figures 1-5 This utility model provides a technical solution: The automatic QR code printing and detection device includes a body 1. An ascending seat 2 is fixedly connected inside the body 1. Mounting seats 3 are symmetrically fixedly connected to the top of the ascending seat 2. Limiting rods 4 are fixedly connected between the mounting seats 3. A receiving platform 5 is slidably connected to the outside of the limiting rods 4. A disc 6 is fixedly connected to the top of the receiving platform 5. A first motor 7 is fixedly connected to the middle of the top of the disc 6. A sleeve 8 is fixedly connected to the output end of the first motor 7. An mounting rod 9 is rotatably connected inside the sleeve 8. A material box 10 is fixedly connected to one end of the mounting rod 9. A printhead 11 is fixedly connected to one end of the material box 10. A cigarette cardboard passes through the body 1, and solvent-based ink is injected into the material box 10. The ink is then sprayed out through the printhead 11, forming a QR code on the surface of the cigarette cardboard. By rotating the first motor 7, the sleeve 8 rotates synchronously, which in turn drives the mounting rod 9 to rotate, thereby adjusting the angle of the printhead 11 and increasing the coding range.

[0018] Furthermore, in this embodiment, a unwinding roller 12 is rotatably connected to the left end of the machine body 1, and a bracket 13 is fixedly connected to the right end of the machine body 1. Two sets of conveying rollers 14 are rotatably connected inside the bracket 13. A second motor 15 is fixedly connected to one end of each set of conveying rollers 14. By placing the cigarette paperboard outside the unwinding roller 12, then passing through the inside of the machine body 1, and exiting from the inside of the riser 2, and finally passing between the two sets of conveying rollers 14, the second motor 15 rotates to achieve frictional conveying of the cigarette paperboard by the conveying rollers 14.

[0019] Furthermore, in this embodiment, a support frame 16 is fixedly connected to the top edge of the disc 6, and an electric telescopic rod 17 is fixedly connected to the top of the disc 6 and between the two sets of support frames 16. An annular disc 18 is fixedly connected to the output end of the electric telescopic rod 17. The support frame 16 is used to lift the annular disc 18. By driving the electric telescopic rod 17, the annular disc 18 is lifted. When the electric telescopic rod 17 is in the initial position, the support frame 16 will support the annular disc 18.

[0020] Furthermore, in this embodiment, an annular groove is provided inside the annular disk 18. One end of the mounting rod 9 is fixedly connected to a connecting rod 19, which has an L-shaped structure. One end of the connecting rod 19 is fixedly connected to a fixed ball 20, which is slidably connected inside the annular groove. As the annular disk 18 is raised, the annular groove will rise synchronously, thereby generating a thrust on the fixed ball 20. After the fixed ball 20 is subjected to the force, it is transmitted to the connecting rod 19, which then enables the mounting rod 9 to rotate inside the sleeve 8, thereby tilting the nozzle 11 and adjusting the up and down angle of the nozzle 11. When the sleeve 8 rotates, the fixed ball 20 will slide inside the annular groove, making the annular groove more stable when adjusting the nozzle 11 left and right.

[0021] Furthermore, in this embodiment, a lead screw 21 is rotatably connected to the middle of the mounting base 3. The lead screw 21 passes through the interior of the receiving platform 5 and is threadedly connected to the receiving platform 5. One end of the lead screw 21 is fixedly connected to a third motor 22. By driving the third motor 22, the lead screw 21 is driven to rotate. Subsequently, the lead screw 21 and the receiving platform 5 undergo a threaded reaction. Under the limit of the limiting rod 4, the receiving platform 5 will directly drive the printhead 11 to reciprocate left and right, further adjusting the printing range of the printhead 11.

[0022] Furthermore, in this embodiment, a first limiting roller 23 and a second limiting roller 24 are rotatably connected inside the machine body 1. The height of the first limiting roller 23 is higher than that of the second limiting roller 24. A display 25 is fixedly connected to the front of the machine body 1. By passing the cigarette paper through the outside of the first limiting roller 23 and the second limiting roller 24, due to the height difference between the first limiting roller 23 and the second limiting roller 24, a part of the cigarette paper is kept on the same horizontal line as the print head 11, which facilitates the print head 11 to print QR codes.

[0023] Furthermore, in this embodiment, the automatic QR code printing and detection device also includes a bonding plate, which is fixedly connected to the top of the machine body 1. A U-shaped frame 26 is fixedly connected inside the bonding plate, and a detection camera 27 is rotatably connected inside the U-shaped frame 26. After the coding is completed, the paperboard will pass through the conveying rollers 14. The detection camera 27 rotates inside the U-shaped frame 26 to scan and monitor the surface of the cigarette paperboard. When a missing code occurs, an alarm will be triggered directly on the display 25.

[0024] In this embodiment, the specific implementation scenario is as follows: The cigarette cardboard is placed outside the unwinding roller 12, then passes through the inside of the machine body 1, then through the outside of the first limiting roller 23 and the second limiting roller 24 respectively, and exits from inside the riser 2. Finally, it passes between the two sets of conveying rollers 14. The second motor 15 rotates to achieve frictional conveying of the cigarette cardboard by the conveying rollers 14. Due to the height difference between the first limiting roller 23 and the second limiting roller 24, a portion of the cigarette cardboard is kept on the same horizontal line as the printhead 11. Solvent-based ink is then injected into the material box 10, and the ink is sprayed out through the printhead 11, forming a QR code on the surface of the cigarette cardboard. The first motor 7 rotates, and the sleeve 8 rotates synchronously with it, subsequently driving the mounting rod 9 to rotate. The fixed ball 20 slides inside the annular groove, which allows the printhead 11 to move left and right. The adjustment is more stable. By driving the electric telescopic rod 17, the annular disc 18 is raised, and the annular groove rises synchronously, which then pushes the fixed ball 20. After the fixed ball 20 is subjected to force, it is transmitted to the connecting rod 19, which then causes the mounting rod 9 to rotate inside the sleeve 8, causing the nozzle 11 to tilt up and complete the vertical angle adjustment of the nozzle 11. By driving the third motor 22, the lead screw 21 is rotated, and then the lead screw 21 reacts with the receiving platform 5. Under the limit of the limit rod 4, the receiving platform 5 directly drives the nozzle 11 to move left and right back and forth, further adjusting the coding range of the nozzle 11. After coding is completed, the cardboard will pass through the conveying rollers 14. The detection camera 27 rotates inside the U-shaped frame 26 to scan and monitor the surface of the cigarette cardboard. If a code is missed, an alarm will be triggered directly on the display 25.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
