DETAILED DESCRIPTION

[0021] The preferred embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-4As shown in the figure, a printing head for controlling the printing range comprises an ink inlet pipe 1, which is connected to the top surface of a mounting shell 2. The outer wall of the ink inlet pipe 1 is fixed with a flange 3. The bottom surface of the mounting shell 2 is connected with a plurality of inkjet heads 4. The top surface of the mounting shell 2 is connected with a plurality of mounting barrels 5. The inside of the plurality of mounting barrels 5 is respectively movably provided with a moving plate 6. The bottom surface of the plurality of moving plates 6 is respectively fixed with a connecting column 7. The bottom surface of the plurality of moving plates 6 is respectively fixed with a spring 8. The bottom end of the plurality of springs 8 is respectively fixedly connected with the inside bottom surface of the plurality of mounting barrels 5. The plurality of springs 8 respectively surround the plurality of connecting columns 7. The bottom end of the plurality of connecting columns 7 is respectively fixed with a sealing plug 9. The outer wall of the rear side of the mounting shell 2 is fixed with a supporting plate 10. The top surface of the supporting plate 10 is fixed with an electric push rod 11. One end of the telescopic rod of the electric push rod 11 is fixed with a connecting frame 12. The bottom surface of the connecting frame 12 is fixed with a plurality of extrusion columns 13. The length of the plurality of extrusion columns 13 respectively decreases from outside to inside.

[0023] In use, the staff first connects the ink inlet pipe 1 with the ink outlet of the printing machine through the flange 3, and then starts the printing machine to make the ink outlet of the printing machine deliver ink into the ink inlet pipe 1. The ink inlet pipe 1 delivers the ink into the mounting shell 2, and then to the inkjet heads 4 for printing. When the staff needs to adjust the printing range, the electric push rod 11 is started to make the connecting frame 12 move downward and in turn drive the plurality of extrusion columns 13 to move downward. Since the length of the plurality of extrusion columns 13 respectively decreases from outside to inside, the leftmost and rightmost extrusion columns 13 respectively extrude the leftmost and rightmost moving plates 6. At this time, the springs 8 are in the extruded state, so that the leftmost and rightmost connecting columns 7 and sealing plugs 9 respectively move downward to block the leftmost and rightmost inkjet heads 4. At this time, the printing can be performed through the four middle inkjet heads 4. When the staff needs to adjust the printing range again, the electric push rod 11 can be started again to make the connecting frame 12 continue to move downward, so that the leftmost and rightmost inkjet heads 4 adjacent to each other are blocked. The printing can be performed through the two middle inkjet heads 4.

[0024] The inkjet heads 4, mounting barrels 5, moving plates 6, connecting columns 7, springs 8, sealing plugs 9, electric push rod 11, connecting frame 12 and extrusion columns 13 can flexibly adjust the printing range according to different printing requirements, improve the flexibility and efficiency of printing, and only a single electric push rod 11 is needed to control the printing range, which is simple to operate, thereby reducing the hardware cost and maintenance cost.

[0025] As shown in the figures, Figure 1 , Figure 2 and Figure 4 , the top surface of the supporting plate 10 is provided with a limiting hole 14. The bottom surface of the connecting frame 12 is fixed with a limiting column 15. The limiting column 15 is slidably inserted into the limiting hole 14.

[0026] In use, the limiting hole 14 and the limiting column 15 facilitate the limiting of the connecting frame 12, which not only ensures the stability of the connecting frame 12 and the extrusion column 13 during lifting, but also effectively prevents deviation and shaking.

[0027] As shown in Figures 1-4 the inside of the ink inlet pipe 1 is detachably provided with a connecting barrel 16, the inside of the connecting barrel 16 is fixedly provided with a filter core 17, the top surface of the ink inlet pipe 1 is provided with two installation grooves 18, the inside bottom surface of each of the two installation grooves 18 is provided with a threaded groove 19, the front side and the rear side of the outer wall of the connecting barrel 16 are fixedly provided with two installation plates 20, the top surface of each of the two installation plates 20 is provided with a threaded hole 21, and the threaded end of each of the two bolts 22 is threadedly connected with the inside of each of the two threaded grooves 19.

[0028] In use, the connecting barrel 16 and the filter core 17 facilitate the removal of impurities and particles in the ink, which ensures the purity and stability of the ink, avoids the blockage and damage of the inkjet head 4 by impurities, and improves the printing effect and clarity. The design of the installation plate 20 and the bolt 22 facilitates the disassembly and assembly of the connecting barrel 16 and the filter core 17. The staff only needs to rotate the bolt 22 to quickly disassemble and replace the connecting barrel 16. This design not only saves time and effort, but also reduces the operation difficulty and complexity.

[0029] As shown in Figures 1-4 the left side and the right side of the outer wall of the connecting barrel 16 are fixedly provided with two positioning blocks 23, the left side and the right side of the inner wall of the ink inlet pipe 1 are provided with two positioning grooves 24, each of the two positioning grooves 24 positions each of the two positioning blocks 23, and the top surface of the flange 3 is fixedly provided with a sealing ring 25.

[0030] In use, the positioning block 23 and the positioning groove 24 facilitate the accurate auxiliary positioning of the installation of the connecting barrel 16, which ensures that the connecting barrel 16 can be quickly and accurately positioned to the correct position during installation, and improves the installation efficiency and accuracy of the connecting barrel 16. The tight fit of the sealing ring 25 on the top surface of the flange 3 provides a reliable sealing effect for the connection of the ink inlet pipe 1 and the ink outlet of the printing machine, effectively preventing the leakage and overflow of the ink, and ensuring the stable delivery of the ink and the reliability of the printing quality.

[0031] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical scheme and the inventive concept of the present application, which should be covered within the protection scope of the present application.
