[0020] like Figure 1-3 As shown, this embodiment provides a printing machine device with an adjustable printing head, comprising: The annular rail 7 has a plurality of positioning holes 701 arranged in an annular array on its side wall; Inkjet cartridge 8, inkjet cartridge 8 is located on the inner side of the annular track 7 and fits with the inner side wall of the annular track 7, and both ends of the inkjet cartridge 8 are resting on the annular track 7 through protrusions 802, the inkjet cartridge 8 can rotate with the center point of the annular track 7 as the center of a circle, and the inkjet cartridge 8 is provided with a mounting groove 805 at the position in contact with the annular track 7, and as the inkjet cartridge 8 rotates, the mounting groove 805 can be concentrically aligned with any positioning hole 701, and an elastic telescopic rod 806 is provided in the mounting groove 805, and the elastic telescopic rod 806 is completely retracted in the mounting groove 805 in a natural state without external force, and a second magnetic block 807 is provided on the movable end of the elastic telescopic rod 806, when the mounting groove 805 is aligned with the positioning hole 701 and the second magnetic block 807 is During adsorption, the movable end of the elastic telescopic rod 806 will extend out of the installation groove 805 and pass through the positioning hole 701. At this time, the elastic telescopic rod 806 is stretched and forms elastic potential energy for retraction. When the adsorption effect on the second magnetic block 807 disappears, the elastic telescopic rod 806 will be completely reset and retracted into the installation groove 805. The inkjet cartridge 8 is provided with a first magnetic block 803 hinged on a protrusion 802 at one end of the installation groove 805. The first magnetic block 803 can be turned over and rest on the outer side wall of the annular rail 7. When the first magnetic block 803 is turned over and rests on the outer side wall of the annular rail 7, the second magnetic block 807 will be adsorbed. When the first magnetic block 803 is reversely turned over to be away from the annular rail 7, the adsorption effect on the second magnetic block 807 disappears. The driving mechanism is used to drive the annular rail 7 to move along the X-axis direction.

[0021] The working principle of the present invention is mainly based on the interaction between the annular rail 7, the inkjet cartridge 8 and the driving mechanism. The annular rail 7 is used as a basic component, and the positioning hole 701 provided on its side wall provides the possibility for positioning the inkjet cartridge 8. The inkjet cartridge 8 is supported on the annular rail 7 through the protrusions 802 at both ends, and can rotate on the inner side of the annular rail 7. An elastic telescopic rod 806 is provided in the mounting groove 805 on the inkjet cartridge 8. When the inkjet cartridge 8 rotates until the mounting groove 805 is aligned with the positioning hole 701 on the annular rail 7, the movable end of the elastic telescopic rod 806 extends out and passes through the positioning hole 701 through the magnetic adsorption effect of the first magnetic block 803 and the second magnetic block 807, thereby fixing the inkjet cartridge 8 in a specific position. At this time, the elastic telescopic rod 806 is stretched and forms elastic potential energy for retraction, providing power for subsequent resetting. When the position of the inkjet cartridge 8 needs to be adjusted, the first magnetic block 803 only needs to be flipped back to be away from the circular rail 7. At this time, the adsorption effect on the second magnetic block 807 disappears, and the elastic telescopic rod 806 is reset and retracted into the installation groove 805 under the action of elastic potential energy, and the inkjet cartridge 8 can be released and the next position adjustment can be performed. The driving mechanism is responsible for driving the circular rail 7 to move along the X-axis direction, thereby driving the inkjet cartridge 8 to move as a whole, and realizing the position adjustment of the printing head in a larger range.

[0022] In summary, the printing head adjustable printing press device of the present invention realizes the self-rotation function of the inkjet cartridge 8 on the inner side of the circular rail 7 through the unique design of the circular rail 7 and the inkjet cartridge 8, and the position of the inkjet cartridge 8 can be accurately fixed by magnetic adsorption and the extension and contraction of the elastic telescopic rod 806. This design not only enables the printing head to be quickly positioned at different positions, but also greatly improves the accuracy and stability of printing. At the same time, the design of the driving mechanism enables the circular rail 7 to move along the X-axis direction, further increasing the range of movement of the printing head and meeting the diversified printing needs. Overall, the technical effect of this patent is to provide a printing press device with a simple structure, easy operation and flexible adjustment, which significantly improves the performance and user experience of the printing press.

[0023] In some embodiments, Figure 1 As shown, the driving mechanism includes an outer frame 1, toothed columns 2 respectively rotatably arranged at the two ends of the inner side of the outer frame 1, a toothed belt 3 wound around the two toothed columns 2 and meshed with the two toothed columns 2, a motor 4 driving any one of the toothed columns 2 to rotate, and a slider 5 slidably arranged on the outer frame 1 and meshed with the toothed belt 3, and the annular rail 7 is connected to the slider 5. As a key component in the printing press device, the driving mechanism is mainly responsible for driving the annular rail 7 and the inkjet cartridge 8 thereon to move accurately and stably along the X-axis direction. The outer frame 1 serves as the supporting structure of the entire driving mechanism and provides a stable installation foundation for other components. The toothed columns 2 are respectively rotatably arranged at the two ends of the inner side of the outer frame 1, and they are connected to the outer frame 1 through bearings or similar mechanisms, and can rotate freely in the outer frame 1. The toothed belt 3 is wound around the two toothed columns 2 and meshed tightly with the toothed columns 2, ensuring the accuracy and continuity of power transmission. The motor 4 is the power source of the driving mechanism, which drives any one of the toothed columns 2 to rotate, thereby driving the toothed belt 3 to circulate between the two toothed columns 2. The slider 5 is slidably disposed on the outer frame 1 and meshes with the toothed belt 3. When the toothed belt 3 moves, it drives the slider 5 to slide along the X-axis direction on the outer frame 1. The annular rail 7 is connected to the slider 5, so when the slider 5 slides, it directly drives the annular rail 7 and the inkjet cartridge 8 thereon to move along the X-axis direction. The gear column 2 is driven to rotate by the motor 4, and then transmitted to the slider 5 via the toothed belt 3, and finally the annular rail 7 and the inkjet cartridge 8 are precisely moved. This transmission method has high precision and stability, can ensure the positioning accuracy of the printing head in the X-axis direction, and meet the requirements of high-precision printing.

[0024] In some embodiments, Figure 1As shown, the annular rail 7 is hinged to the slider 5 via a damping hinge of a connecting plate 6. Specifically, one end of the connecting plate 6 is fixedly connected to the annular rail 7, and the other end is connected to the slider 5 via a damping hinge. The design of the damping hinge enables the annular rail 7 to be adjusted to an angle of upward or downward within a certain range. This flexibility is essential to adapt to different printing needs, especially in situations where the angle between the print head and the printed material needs to be adjusted. By simply adjusting the angle of the annular rail 7, the best alignment between the print head and the printed material can be achieved, thereby improving the printing quality. Moreover, the damping hinge not only allows the annular rail 7 to be adjusted in angle, but also maintains the set angle. This means that during the printing process, even if disturbed by external forces, the annular rail 7 can maintain a stable angle, ensuring that the relative position between the print head and the printed material remains unchanged, thereby maintaining the consistency and accuracy of the printing.

[0025] In some embodiments, Figure 3 As shown, the first magnetic block 803 is provided with a protruding plectrum 804. Specifically, the plectrum 804 is fixedly connected to the first magnetic block 803 and extends outward to form a structure that is convenient for the operator to hold and plectrum. The design of the plectrum 804 enables the operator to flip the first magnetic block 803 more easily without directly contacting the first magnetic block 803 itself, thereby improving the convenience and safety of operation. On the one hand, the design of the plectrum 804 provides the operator with a larger contact area and a structure that is easier to hold, making it easier and faster to flip the first magnetic block 803. The operator only needs to gently plectrum 804 to achieve the flipping of the first magnetic block 803, without the need to directly grab or pinch the first magnetic block 803 with effort, thereby improving work efficiency. On the other hand, the plectrum 804 is provided on the first magnetic block 803 to prevent the operator from directly contacting the first magnetic block 803, reducing the safety hazards caused by accidental touch or improper operation. Especially in situations where the first magnetic block 803 needs to be frequently flipped for position adjustment, the design of the paddle 804 can significantly reduce the risk during operation.

[0026] In some embodiments, Figure 1 As shown, the ink replenishing box 10 is also included, and an ink supply tube 9 is connected between the ink replenishing box 10 and the inkjet box 8. Specifically, the ink replenishing box 10 is an independent ink storage container, which is connected to the inkjet box 8 through the ink supply tube 9. When the ink in the inkjet box 8 is about to be exhausted or needs to be replenished, the ink in the ink replenishing box 10 can be replenished to the inkjet box 8 in time through the ink supply tube 9, ensuring the continuity and stability of the printing process. This design avoids the interruption of printing due to the exhaustion of ink in the inkjet box 8, ensuring the continuity and efficiency of the printing process. Especially in the occasions of large-scale printing or long-term continuous printing, the design of the ink replenishing box 10 can significantly improve the printing efficiency.

[0027] In some embodiments, Figure 1-2 As shown, the ink supply tube 9 is connected to the inkjet cartridge 8 through a rotary joint 801. Specifically, the rotary joint 801 is arranged at the connection between the ink supply tube 9 and the inkjet cartridge 8, which allows the ink supply tube 9 to rotate within a certain range while maintaining a tight connection with the inkjet cartridge 8. This design enables the ink supply tube 9 to adapt to the rotation of the inkjet cartridge 8 on the annular rail 7, avoiding the ink supply tube 9 from being twisted, deformed or leaked due to the rotation of the inkjet cartridge 8. The introduction of the rotary joint 801 makes the connection between the ink supply tube 9 and the inkjet cartridge 8 more flexible. In the process of the inkjet cartridge 8 rotating to adjust the position of the print head, the rotary joint 801 can rotate freely with the rotation of the inkjet cartridge 8, thereby avoiding the stress concentration and damage caused by the twisting or pulling of the ink supply tube 9. This design prolongs the service life of the ink supply tube 9 and reduces the equipment failure rate caused by connection problems.
