Multiple connecting blocks 9 are slidably connected to both the front and rear sides of the inner wall of the base 1. Adjusting rollers 10 are rotatably connected to opposite ends of each connecting block 9. A connecting frame 8 is fixedly connected to the lower side of the adjusting roller 10 at the opposite end of the left connecting block 9. A sliding frame 5 is provided on the inner wall of the connecting frame 8. A motor 2 is provided at the bottom end of the sliding frame 5. The bottom end of the motor 2 is fixedly connected to the lower side of the inner wall of the base 1. A guide roller 19 is rotatably connected to the inner wall of the base 1. A scissor frame 6 is rotatably connected to the inner wall of the sliding frame 5. The other end of the scissor frame 6... Each component is rotatably connected to a slider 7. The outer walls of the slider 7 are slidably connected to the front and rear sides of the inner wall of the connecting frame 8. The inner walls of the adjacent left and right connecting blocks 9 are rotatably connected to telescopic frames 11. The opposite ends of the telescopic frames 11 are rotatably connected to the front and rear sides of the inner wall of the base 1 to adjust the distance between the two adjusting rollers 10. The drive end of the motor 2 is fixedly connected to a gear 3. The outer walls of the gear 3 are meshed with toothed plates 4 on the left and right sides. The opposite ends of the toothed plates 4 are slidably connected to the left and right sides of the inner wall of the base 1. The top ends of the toothed plates 4 are fixedly connected to the bottom of the sliding frame 5 to drive the sliding frames 5 on both sides to move.
[0033] Specifically, a controller is set at the front end of the base 1. The controller is electrically connected to motor 12 and motor 2. Through the height-adjustable design, the height of the two adjusting rollers 10 can be adjusted at the same time, so as to adjust according to the tension required by the material, ensuring that the tension of the paper is uniform across the entire width, avoiding blurry, ghosting or color issues in the printed pattern. At the same time, uniform tension distribution helps the paper to remain stable during transmission, improves the registration accuracy of multi-color printing, ensures pattern alignment, and improves product quality.
[0034] Reference Figure 1 , Figure 5 and Figure 6 As shown in Embodiment 2: The outer walls of the rotating drum 13 are rotatably connected to the front and rear sides of the inner wall of the base 1. The inner wall of the rotating drum 13 is provided with a drum body 15. The rear end of the base 1 is fixedly connected to a motor 12. The driving end of the motor 12 is fixedly connected to the rear end of the rotating drum 13. The inner wall of the drum body 15 is slidably connected to a pull plate 16. The bottom end of the pull plate 16 is fixedly connected to a locking block 17. The inner wall of the rotating drum 13 is provided with a locking groove 14. The outer wall of the locking block 17 is provided on the inner wall of the locking groove 14. The shape of the locking block 17 fits the locking groove 14. The opposite end of the locking block 17 is fixedly connected to a spring 18. The other end of the spring 18 is fixedly connected to the front and rear sides of the inner wall of the drum body 15 for disassembly and assembly of the drum body 15.
[0035] Specifically, during disassembly, simply pull the pull plate 16. The pull plate 16 will cause the locking block 17 to be removed from the locking slot 14, thus removing the roll body 15 from the rotating drum 13. The detachable design allows for convenient and quick replacement of the roll body 15. The operation is simple, which can significantly reduce downtime, ensure continuous operation of the printing press, and improve overall production efficiency.
[0036] Working principle: First, when installing the roll body 15, pull the pull plate 16. The pull plate 16 moves the locking block 17, moving the roll body 15 to the opposite end of the rotating drum 13. After it is in place, release the pull plate 16. The spring 18 then engages the locking block 17 into the slot 14, completing the installation. A portion of the material is then moved to the top of the left adjusting roller 10, passes through the bottom of the right adjusting roller 10, and then through the top of the guide roller 19, and is installed in the printing press. Next, the controller can be used to start the motor 2. The motor 2 drives the gear 3 to rotate, and the gear 3 drives the toothed plates 4 on both sides to slide. The motor moves, causing the sliding frame 5 to move, and the scissor frame 6 to rotate, causing the sliders 7 on both sides to slide. The sliders 7 slide on the inner wall of the connecting frame 8, causing the connecting frame 8 to move up and down. At the same time, the connecting block 9 on the left side moves. When the connecting block 9 on the left side moves, the connecting block 9 on the right side and the adjusting roller 10 on the right side move in the opposite direction through the telescopic frame 11, so that the height of the adjusting rollers 10 on both sides can be adjusted according to the tension of the material. After the adjustment is completed, the motor 12 is turned off and the motor 212 is turned on. The motor 212 drives the rotating drum 13 and the drum body 15 to rotate to transport the raw materials.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
