Description

Technical Field

[0001] This utility model relates to the technical field of printhead fine-tuning devices for UV inkjet coding systems, specifically a printhead height fine-tuning device for a UV inkjet coding system. Background Technology

[0002] UV inkjet printing is a new type of inkjet printing technology that relies on UV ultraviolet light to instantly cure ink. Its core features are fast marking and strong adhesion. It can adapt to a variety of complex materials and is widely used in the field of industrial marking. The UV inkjet printing process is simple and efficient. There is no need to wait for the ink to dry naturally. The whole process can be completed within 1 second. The adjustment of the printhead height in the UV inkjet printing system is a very important part of the entire UV inkjet printing process, which affects the clarity of the printed graphics.

[0003] However, existing UV inkjet coding systems typically only allow for vertical height adjustment of the printhead. This type of adjustment mechanism can only be used for coding paper with uniform thickness and cannot adapt to paper with different thicknesses on both sides, thus having significant limitations. Therefore, it does not meet current requirements. To address this, we propose a UV inkjet coding system printhead height adjustment device. Utility Model Content

[0004] The purpose of this invention is to provide a printhead height fine-tuning device for a UV inkjet coding system, in order to solve the problem that the printhead height fine-tuning devices for UV inkjet coding systems mentioned in the background art can usually only adjust the height longitudinally. Such adjustment mechanisms can only be used for coding on paper with uniform thickness, and cannot adapt to coding on paper with different thicknesses on both sides, which is a high limitation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printhead height fine-tuning device for a UV inkjet coding system, comprising a longitudinal adjustment slide: A UV inkjet printer is installed on the front end face of the longitudinal adjustment slide. The longitudinal adjustment slide is fixedly connected to the UV inkjet printer. A fixed mounting plate is installed on the lower end of the UV inkjet printer. The fixed mounting plate is fixedly connected to the UV inkjet printer. Pressure probes are installed on both sides of the lower end of the fixed mounting plate. The pressure probes are fixedly connected to the fixed mounting plate. The mounting bracket is installed at the rear end of the longitudinal adjustment slide. Limiting guide rails are installed on both sides of the front end face of the mounting bracket, and these guide rails are connected to the mounting bracket by screws. The limiting guide rails are also slidably connected to the longitudinal adjustment slide via slots. A connecting boss is installed at the rear end of the mounting bracket, and this boss is fixedly connected to the mounting bracket. A fixing back plate is installed at the rear end of the connecting boss, and this back plate is rotatably connected to the connecting boss via bearings. An angle fine-tuning motor is installed on the rear end face of the fixing back plate, and this motor is connected to the fixing back plate by screws. The angle fine-tuning motor is also connected to the connecting boss via a coupling.

[0006] Preferably, a fine-tuning controller is installed on the rear end face of the mounting bracket, and the fine-tuning controller is fixedly connected to the mounting bracket.

[0007] Preferably, a mounting connecting plate is installed at one end of the fixed back plate, and the mounting connecting plate is welded to the fixed back plate.

[0008] Preferably, longitudinal adjusting screws are installed on both sides of the front end face of the mounting bracket. The longitudinal adjusting screws are connected to the mounting bracket via bearings, and the longitudinal adjusting screws are connected to the longitudinal adjusting slide via ball screw and nut pairs.

[0009] Preferably, drive motors are installed on both sides of the upper surface of the mounting bracket, the drive motors are connected to the mounting bracket by screws, and the drive motors are connected to the longitudinal adjusting screw by a coupling.

[0010] Preferably, the upper end of the UV inkjet printer is equipped with a connection port, and the connection port is configured with different specifications.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by installing pressure probes, enables the device to detect the thickness of both sides of the paper. This facilitates the device's control of the UV coding printhead to make adjustments, ensuring that the ink-jet surface at the lower end of the UV coding printhead is parallel to the paper. This prevents the ink-jet surface at the lower end of the UV coding printhead from being non-parallel to the upper end of the paper, ensuring that the distances from both ends of the UV coding printhead to both ends of the paper are the same. This results in clearer and more accurate graphics printed by the UV coding printhead, enhancing the device's practicality. The installation angle fine-tuning motor can drive the mounting bracket to rotate, thereby fine-tuning the angle of the UV coding printhead to make the lower end of the UV coding printhead parallel to the paper. This ensures that the pressure probes on both sides of the device contact the paper simultaneously with the same pressure during adjustment. This allows the UV coding printhead to perform high-precision coding not only on paper with uniform thickness on both sides but also on paper with different thicknesses on both sides, enhancing the device's applicability. 2. This utility model can control the longitudinal adjustment slide and UV inkjet printhead to move longitudinally with high precision by installing a longitudinal adjustment screw, which reduces the difficulty of adjusting the height of the longitudinal adjustment slide and UV inkjet printhead and makes the device more user-friendly.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-3 One embodiment of this utility model is a printhead height fine-tuning device for a UV inkjet coding system, comprising a longitudinal adjustment slide 1. The UV inkjet printhead 2 is installed on the front end of the longitudinal adjustment slide 1. The longitudinal adjustment slide 1 is fixedly connected to the UV inkjet printhead 2. A fixed mounting plate 10 is installed on the lower end of the UV inkjet printhead 2. The fixed mounting plate 10 is fixedly connected to the UV inkjet printhead 2. Pressure probes 11 are installed on both sides of the lower end of the fixed mounting plate 10. Installing pressure probes 11 allows the device to detect the thickness of both sides of the paper, which facilitates the device to control the UV inkjet printhead 2 to make adjustments so that the ink-jetting surface of the lower end of the UV inkjet printhead 2 is parallel to the paper. This avoids the ink-jetting surface of the lower end of the UV inkjet printhead 2 being non-parallel to the upper end of the paper, ensuring that the distance from both ends of the UV inkjet printhead 2 to both ends of the paper is the same, making the graphics printed by the UV inkjet printhead 2 clearer and more accurate, and enhancing the practicality of the device. The pressure probes 11 are fixedly connected to the fixed mounting plate 10. Mounting bracket 4 is installed at the rear end of the longitudinal adjustment slide 1. Limiting guide rails 5 are installed on both sides of the front face of mounting bracket 4, and the limiting guide rails 5 are connected to mounting bracket 4 by screws. The limiting guide rails 5 are longitudinally slidably connected to the longitudinal adjustment slide 1 via slots. A connecting boss 14 is installed at the rear end of mounting bracket 4, and the connecting boss 14 is fixedly connected to mounting bracket 4. A fixing back plate 8 is installed at the rear end of connecting boss 14, and the fixing back plate 8 is rotatably connected to connecting boss 14 via bearings. An angle fine-tuning motor 12 is installed on the rear face of fixing back plate 8, which adjusts the mounting angle. The adjusting motor 12 can drive the mounting bracket 4 to rotate, thereby fine-tuning the angle of the UV inkjet printhead 2, so that the lower end face of the UV inkjet printhead 2 is parallel to the paper. This ensures that the pressure probes 11 on both sides of the device contact the paper simultaneously and with the same pressure during adjustment. This allows the UV inkjet printhead 2 to perform high-precision printing not only on paper with uniform thickness on both sides, but also on paper with different thicknesses on both sides, enhancing the applicability of the device. The angle fine-tuning motor 12 is connected to the fixed back plate 8 by screws, and the angle fine-tuning motor 12 is connected to the connecting boss 14 by a coupling.

[0016] Please see Figure 1 , Figure 2 and Figure 3 A fine-tuning controller 13 is installed on the rear end face of the mounting bracket 4. The fine-tuning controller 13 is fixedly connected to the mounting bracket 4. A mounting connecting plate 9 is installed on one end of the fixed back plate 8. The mounting connecting plate 9 is welded to the fixed back plate 8. Both sides of the front face of the mounting bracket 4 are equipped with longitudinal adjusting screws 6. The longitudinal adjusting screws 6 can control the longitudinal adjusting slide 1 and the UV inkjet printhead 2 to move longitudinally with high precision, reducing the difficulty of adjusting the height of the longitudinal adjusting slide 1 and the UV inkjet printhead 2, making the device more user-friendly. The longitudinal adjusting screws 6 are connected to the mounting bracket 4 through bearings. The longitudinal adjusting screws 6 are connected to the longitudinal adjusting slide 1 through a ball screw nut pair. Both sides of the upper end face of the mounting bracket 4 are equipped with drive motors 7. The drive motors 7 are connected to the mounting bracket 4 through screws. The drive motors 7 are connected to the longitudinal adjusting screws 6 through couplings. The upper end of the UV inkjet printhead 2 is equipped with a connection port 3, which is set to different specifications.

[0017] Working Principle: During use, the device is installed on the horizontal adjustment mechanism of the UV coding system. When fine-tuning is required, the drive motor 7 rotates the vertical adjustment screw 6, causing the vertical adjustment slide 1 to lower the UV coding head 2, bringing the pressure probe 11 into contact with the paper. If both pressure probes 11 on both sides of the device contact the paper simultaneously with equal pressure, it indicates that the paper thickness is the same on both sides. The distance from the bottom of the pressure probe 11 to the lower inkjet surface of the UV coding head 2 is fixed, allowing the device to automatically calibrate the distance between the lower inkjet surface of the UV coding head 2 and the paper. The operator can then control the UV coding head 2 to rise to the appropriate height according to inkjet requirements. If the pressure probes 11 on both sides of the device do not contact the paper and the pressures are different, the drive motor 7 stops controlling the descent of the UV coding head 2. At this time, the angle fine-tuning motor 12 rotates the mounting bracket 4, causing the mounting bracket 4 to rotate towards the pressure probe 11 on the side not in contact with the paper, until both pressure probes 11 on both sides of the device contact the paper with equal pressure. This achieves automatic adjustment of the UV coding head 2 and the paper. Horizontal calibration: The pressure probe 11 installed in this device allows it to detect the thickness on both sides of the paper, facilitating adjustments to the UV inkjet printhead 2. This ensures the lower inkjet surface of the UV inkjet printhead 2 is parallel to the paper, preventing misalignment between the lower inkjet surface of the UV inkjet printhead 2 and the upper surface of the paper. This guarantees that the distances from both ends of the UV inkjet printhead 2 to both ends of the paper are equal, resulting in clearer and more accurate graphics and enhancing the device's practicality. The installation angle fine-tuning motor 12 can rotate the mounting bracket 4, thereby adjusting the angle of the UV inkjet printhead 2. Fine-tuning ensures that the lower end face of the UV inkjet printhead 2 is parallel to the paper, guaranteeing that the pressure probes 11 on both sides of the device contact the paper simultaneously with the same pressure during adjustment. This allows the UV inkjet printhead 2 to perform high-precision coding not only on paper with uniform thickness on both sides but also on paper with different thicknesses on both sides, enhancing the device's applicability. Installing the longitudinal adjustment screw 6 allows for high-precision control of the longitudinal adjustment slide 1 and the UV inkjet printhead 2 to move longitudinally, reducing the difficulty of adjusting the height of the longitudinal adjustment slide 1 and the UV inkjet printhead 2 and making the device more user-friendly.
