[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1: This Example 1 provides a gradient combination printhead for a thermal inkjet printer. It is a direct improvement on an existing printhead and has a unique structure. Please refer to [link / reference]. Figure 1-4 As shown, the system includes a slide rail 1 fixedly connected to the printer body. Multiple sliders 2 are slidably mounted on the slide rail 1 at intervals along its length. The top of each slider 2 has a threaded hole, and a limit bolt 3 is threaded into the threaded hole. A U-shaped plate 4 is also fixedly mounted on the top of the slider 2, arranged vertically. A printer nozzle 5 is slidably mounted inside the U-shaped plate 4, and an ink ejection slot 6 is provided on the side wall of the U-shaped plate 4. A rack 7 is fixedly mounted on both sides of the slot 6, arranged vertically. A drive box 8 is provided on the side of the U-shaped plate 4 away from its opening. The drive box 8 is fixedly connected to the printer nozzle 5, and an avoidance slot 9 is provided on the drive box 8 to avoid the rack 7. A rotating shaft 11 and a worm gear 14 are rotatably mounted inside the drive box 8. A worm wheel 12 is fixedly mounted in the middle of the rotating shaft 11, and the worm wheel 12 meshes with the worm gear 14 for transmission.

[0018] There are several ways to install the rotating shaft 11 and the worm gear 14. For example, both ends of the rotating shaft 11 are fitted with bearings, and the rotating shaft 11 is rotatably connected to the drive box 8 through the bearings. Both ends of the worm gear 14 are fitted with bearing seats 16, and both bearing seats 16 are fixedly connected to the drive box 8. The worm gear 14 is rotatably connected to the drive box 8 through the bearing seats 16. There are several ways to connect the drive box 8 to the printer nozzle 5. For example, the drive box 8 is open at one end near the U-shaped plate 4, and L-shaped bearings are fixedly installed on the upper and lower side walls of the opening of the drive box 8. Plate 10, two L-shaped plates 10 are located between two adjacent clearance grooves 9, and the other end of the two L-shaped plates 10 extends into the groove 6 and is bolted to the bottom of the printer nozzle 5. The bolt connection facilitates the disassembly and replacement of the printer nozzle 5. Gears 13 are fixedly mounted on the rotating shafts 11 on both sides of the worm gear 12. The two gears 13 mesh with the racks 7 on the adjacent sides respectively. The end of the worm 14 away from the U-shaped plate 4 passes through the drive box 8, and a hexagonal groove 15 is opened on the exposed end face of the worm 14.

[0019] Working principle: The number of printer printheads 5 can be 1-8, which can be installed according to the needs of the site. In the initial state, only one printer printhead 5 is used for printing. When there is a lot of information to be printed on the cigarette pack, multiple printer printheads 5 can be installed on the slide rail 1, so that each printer printhead 5 is responsible for printing different content or areas. For example, one printer printhead 5 is dedicated to printing fixed text, another printer printhead 5 prints variable dates, and another printer printhead 5 prints counter information. In this way, multiple different types of information can be printed on the product surface at the same time, improving printing efficiency and information richness. In addition, the horizontal and vertical distance between two adjacent printer printheads 5 can be flexibly adjusted according to the different positions of the information on the cigarette pack.

[0020] When adjusting the horizontal distance between two adjacent printer nozzles 5, simply loosen the limiting bolt 3 on the slider 2 to be adjusted, and then push the slider 2 to move. When it reaches the preset position, tighten the limiting bolt 3 again so that the screw of the limiting bolt 3 abuts against the slide rail 1, thereby fixing the slider 2 again. When it is necessary to adjust the vertical distance between two adjacent printer nozzles 5, simply insert an Allen wrench into the hexagonal groove 15, and then drive the worm gear 14 to rotate. After the worm gear 14 rotates, it drives the worm wheel 12 to rotate through meshing transmission, and then drives the printer nozzle 5 to move up and down through the meshing transmission of the gear 13 and the rack 7, thereby changing the height of the printer nozzle 5.

[0021] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 1-2 As shown, vertical grooves are provided on both opposite surfaces of the U-shaped plate 4, and movable blocks are slidably installed in the grooves. Both movable blocks are fixedly connected to the printer nozzles 5. Scale lines are provided vertically on the slide rail 1 and on both sides of the middle horizontal plate of the U-shaped plate 4. Through the design of the grooves and movable blocks, the printer nozzles 5 move more smoothly up and down. In addition, the scale lines allow operators to more accurately adjust the horizontal and vertical distances between adjacent printer nozzles 5.

[0022] 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.
