Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings.
[0027] Please see Figure 1-4 As shown, this embodiment provides a printing device for easy positioning of packaging boxes, including: a box body 1, with grooves 4 on both the left and right side walls inside the box body 1, a driving component connected inside the grooves 4, a connecting block 8 connected to the driving component, and a fixing plate 9 connected to the connecting block 8 through an adjusting component; the driving component includes a rotating gear 5 rotatably connected to the grooves 4, a driving gear 6 meshing below the rotating gear 5, and a motor 7 connected to the driving gear 6; and a printing component connected to the top of the box body 1.
[0028] The grooves 4 on the left and right side walls of the housing 1 serve as the mounting carrier for the drive assembly, providing a spatial basis for subsequent operations. Inside the drive assembly, the rotating gear 5 is rotatably connected to the groove 4, allowing it to rotate flexibly within the groove 4. The drive gear 6 meshes with the rotating gear 5. When the motor 7 drives the drive gear 6 to rotate, the drive gear 6, through the meshing relationship, drives the rotating gear 5 to rotate, thereby transmitting the power of the motor 7. The connecting block 8 is connected to the rotating gear 5. The rotation of the rotating gear 5 will drive the connecting block 8 to rotate. After one side of the packaging box is printed, the packaging box is rotated by rotating the connecting block 8, achieving the purpose of printing the other side without disassembling and reinstalling the packaging box. The connecting block 8 is connected to the fixing plate 9 through the adjusting component. The fixing plate 9 achieves horizontal movement through the adjusting component, facilitating the clamping and fixing of packaging boxes of different sizes. After the packaging box is positioned, the printing assembly can begin printing.
[0029] In this embodiment, a drying assembly is connected to the bottom wall of the box 1. The drying assembly includes a drying box 3 located directly below the fixing plate 9. A hot air generator is installed inside the drying box 3. Multiple air outlet holes 16 are evenly distributed on the surface of the drying box 3. The air outlet holes 16 are conical in shape. The diameter of the holes on the surface of the drying box 3 is larger than the diameter of the holes on the inner wall of the drying box 3.
[0030] The hot air generator is installed inside the drying box 3. After being powered on, it can generate stable hot air. This hot air will be blown directionally onto the printed surface of the packaging box through the air outlet 16 on the surface of the drying box 3, accelerating the evaporation of solvents in the ink, thereby achieving the purpose of drying the ink. The special shape design of the air outlet 16 will produce a diffuser-like effect when the hot air flows from the inner wall with a smaller aperture to the surface with a larger aperture. According to the principle of fluid dynamics, the flow rate of the hot air decreases and the pressure increases when it passes through the gradually expanding channel, so that the hot air can be blown onto the surface of the packaging box with a larger coverage area and more uniform pressure.
[0031] The connecting block 8 is fixedly connected to the surface of the rotating gear 5 via a rotating shaft. The connecting block 8 has an inner cavity 15. The adjusting component includes a connecting sleeve 10 connected to the side wall of the fixing plate 9. The connecting sleeve 10 passes through the side wall of the connecting block 8 and is located inside the connecting block 8. The adjusting component also includes a lead screw 14. One end of the lead screw 14 is threadedly connected to the connecting sleeve 10, and the other end is located in the inner cavity 15 and connected to a worm gear 12. The bottom end of the worm gear 12 is meshed with a worm 13. One end of the worm 13 is rotatably connected to the side wall of the inner cavity 15, and the other end passes through the connecting block 8 and is connected to a throttle handle 11.
[0032] The connecting block 8 is fixedly connected to the surface of the rotating gear 5 via a rotating shaft. When the rotating gear 5 rotates under the drive of the drive assembly, it can synchronously drive the connecting block 8 to rotate, realizing the flipping operation of the packaging box. The connecting sleeve 10 is connected to the side wall of the fixing plate 9, extends through the side wall of the connecting block 8 into the inner cavity 15, and serves as the connection hub between the fixing plate 9 and the lead screw 14. It moves horizontally with the rotation of the lead screw 14, thereby driving the fixing plate 9 to achieve displacement. When the handle 11 is turned, the worm 13 rotates accordingly. Since the worm wheel 12 meshes with the worm 13, the rotation of the worm 13... The drive worm gear 12 rotates, which in turn drives the lead screw 14 to rotate. According to the principle of thread transmission, the rotation of the lead screw 14 is converted into the linear motion of the connecting sleeve 10, causing the fixing plate 9 to move horizontally along the direction of the lead screw 14, thereby adjusting the clamping width of the packaging box. By rotating the handle 11, the adjustment component can precisely adjust the spacing of the fixing plate 9. Whether it is a small and exquisite gift box or a large commodity packaging box, it can quickly achieve stable clamping, which greatly improves the versatility of the printing device and reduces the equipment replacement or adjustment costs caused by differences in packaging box size.
[0033] The printing assembly includes a printing head 2, which is connected to the inner wall of the top of the housing 1 via a lifting cylinder, and the printing head 2 is connected to an ink supply pipe.
[0034] The printing head 2 is connected to the inner wall of the housing 1 via a lifting cylinder. The piston rod of the lifting cylinder extends and retracts, causing the printing head 2 to adjust its vertical position. When printing is required, the cylinder pushes the printing head 2 down to a suitable height. After printing is completed, the cylinder drives the printing head 2 up to reset, avoiding collision with the packaging box. The ink supply pipeline is connected to the printing head 2, continuously providing a stable ink supply to the printing head 2. The pipeline is connected to an external ink storage device (such as an ink tank) and is equipped with a pressure regulating device to ensure that the ink is delivered to the printing head 2 at a constant pressure, ensuring consistent printing quality.
[0035] Working principle:
[0036] In use, the operator rotates the handle 11 of the adjustment component according to the size of the packaging box. The worm gear 13 rotates accordingly, driving the worm wheel 12 that meshes with it to rotate, which in turn causes the lead screw 14 to rotate. Since the lead screw 14 is threadedly connected to the connecting sleeve 10, the rotation of the lead screw 14 is converted into the linear motion of the connecting sleeve 10, which drives the fixing plate 9 to move horizontally along the direction of the lead screw 14. The spacing of the fixing plate 9 is precisely adjusted to achieve a stable clamping of packaging boxes of different sizes. The connecting block 8 is fixedly connected to the rotating gear 5 through the rotating shaft. When the drive component is not started, the connecting block 8 and the fixing plate 9 together fix the packaging box to ensure stable position before printing.
[0037] Once the packaging box is positioned, the printing assembly begins operation. The piston rod of the lifting cylinder extends, pushing the printing head 2 down to a suitable height, maintaining a precise distance from the printing surface of the packaging box. The ink supply pipeline connects to an external ink storage device, and through a pressure regulating device, ink is delivered to the printing head 2 at a constant pressure. The precision structure inside the printing head 2, such as nozzles or printing plates, applies ink evenly to the surface of the packaging box according to the preset pattern, completing single-sided printing. After printing is completed, the lifting cylinder drives the printing head 2 to rise and reset, avoiding collision with the packaging box.
[0038] After single-sided printing is completed, the drive assembly is started. The motor 7 drives the drive gear 6 to rotate. The drive gear 6 meshes with the rotating gear 5, transmitting power to the rotating gear 5, which rotates flexibly in the groove 4. The rotating gear 5 drives the connecting block 8 to rotate 180° synchronously through the rotating shaft, realizing the flipping of the packaging box without the need for disassembly and reinstallation. At the same time, the drying assembly located directly below the fixed plate 9 starts to operate. The hot air generator produces stable hot air, which is sprayed out through the conical air outlet 16 on the surface of the drying box 3. According to the principle of fluid mechanics, when the hot air passes through the channel with gradually expanding aperture, the flow rate decreases and the pressure increases, so as to blow the printed surface of the packaging box with a larger coverage area and uniform pressure, accelerating the evaporation of solvent in the ink and completing the ink drying.
[0039] After the packaging box is flipped and dried, the printing component restarts and repeats the single-sided printing process to complete the printing on the other side of the packaging box. Throughout the process, the components work together to achieve an automated cycle from packaging box positioning, single-sided printing, flipping and drying to double-sided printing, which greatly improves printing efficiency and quality. The precise positioning of the adjustment component, the stable flipping of the drive component, the accurate printing of the printing component, and the efficient drying of the drying component together ensure the adaptability of the printing device to packaging boxes of different sizes and the consistency of printing effect.
