[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0033] This utility model provides, for example Figures 1 to 3 The ink drying device for a continuous printing press shown includes a drying chamber 1. The drying chamber 1 contains a drying room 11, a control room 12, and an equipment room 13. The drying room 11 contains a drying assembly, which includes a guide plate 2, a heating plate 21, a feed roller 22, a guide roller 23, a discharge roller 24, a support roller 37, a heating fan 4, a first drying pipe 43, an exhaust port 44, a second drying pipe 45, and an exhaust head 46. The feed roller 22, guide roller 23, and discharge roller 24... A printing substrate 14 is provided between the support roller 37 and the printing substrate 14. The guide plate 2 is fixedly installed inside the drying chamber 11 near the upper side. The heating plate 21 is fixed inside the guide plate 2. The feed roller 22, the guide roller 23, and the discharge roller 24 are all rotatably connected to the inner walls of the front and rear sides of the drying chamber 11. The feed roller 22 is located on the left side of the guide plate 2, the guide roller 23 is located on the right side of the guide plate 2, the discharge roller 24 is located below the guide roller 23, and the support roller 37 is located below the feed roller 22.
[0034] During the feeding process, the printed substrate 14 is fed into the drying chamber 11 from the left feed port. After entering the drying chamber 11, it overlaps the surface of the feed roller 22, and then is pulled to the right to overlap the inside of the guide roller 23. Next, the substrate 14 is moved around the guide roller 23 and pulled to the left, then around the support roller 37 and passes under the discharge roller 24. Finally, it is discharged from the drying chamber 11 through the discharge port. At this time, the unprinted portion of the substrate 14 between the feed roller 22, guide roller 23, and support roller 37 is left un-printed. The side surface overlaps the upper surface of the guide plate 2, causing the substrate 14 to move in a Z-shaped trajectory inside the drying chamber 11. This effectively increases the length of the substrate 14 inside the drying chamber 1. The heating plate 21, guide plate 2, first drying tube 43, and second drying tube 45 work together to dry the substrate 14, allowing normal conveying speed to be maintained inside the relatively small drying chamber 1, while ensuring the drying effect on the surface of the substrate 14. This achieves improved drying efficiency for the substrate 14 within the smaller drying chamber 1.
[0035] See Figure 1 , Figure 2 and Figure 5 Multiple sets of first drying pipes 43 are fixedly connected between the inner walls of the front and rear sides of the drying chamber 11. Multiple sets of exhaust holes 44 are opened on the surface of the first drying pipes 43. The multiple sets of first drying pipes 43 are arranged in sequence between the discharge roller 24 and the support roller 37. Multiple sets of second drying pipes 45 are fixedly connected to the upper surface of the drying box 1. Multiple sets of exhaust heads 46 are fixedly connected to the surface of the second drying pipes 45. The lower end of the exhaust head 46 extends through the upper wall of the drying box 1 and into the drying chamber 11. The heating fan 4 is fixedly installed inside the control room 12. Ventilation holes 15 are opened on both the front and rear sides of the control room 12. The air outlet of the heating fan 4 is fixedly connected to the air supply pipe 41. Two diversion pipes 42 are fixedly connected to the surface of the air supply pipe 41. The front end of the first drying pipe 43 is fixedly connected to the lower diversion pipe 42, and the front end of the second drying pipe 45 is fixedly connected to the upper diversion pipe 42.
[0036] In addition, the heating fan 4 draws in external air and heats the drawn-in air. Then, the hot air is sent into the air supply pipe 41 through the air outlet. The air supply pipe 41 delivers the hot air to the interior of multiple sets of first drying pipes 43 through the lower diversion pipe 42 and discharges it through multiple sets of exhaust holes 44 on the surface of the first drying pipes 43. At the same time, the hot air is delivered to the interior of multiple sets of second drying pipes 45 through the upper diversion pipe 42 and discharges it through multiple sets of exhaust heads 46 on the surface of the second drying pipes 45.
[0037] Specifically, during the conveying of the substrate 14, the heating plate 21 heats the upper and lower surfaces of the guide plate 2. The second drying tube 45 works with the guide plate 2 to dry the portion of the substrate 14 that slides on the upper surface of the guide plate 2. Then, the first drying tube 43 works with the guide plate 2 to dry the portion of the substrate 14 that slides on the lower surface of the guide plate 2. Finally, the first drying tube 43 dries the portion of the substrate 14 between the support roller 37 and the discharge roller 24.
[0038] See Figure 3 and Figure 4 A hydraulic cylinder 31 is fixedly installed inside the equipment chamber 13. An adjusting plate 3 is fixedly connected to the upper end of the telescopic rod in the hydraulic cylinder 31. Two sets of guide rods 34 are slidably connected to both ends of the adjusting plate 3. A connecting block 36 is fixedly connected to the upper end of the two sets of guide rods 34 on the same side. The two ends of the support roller 37 are rotatably connected to the two sets of connecting blocks 36 respectively. A support spring 35 is sleeved on the surface of the guide rod 34. The upper and lower ends of the support spring 35 abut against the surfaces of the connecting block 36 and the adjusting plate 3 respectively. Positioning cylinders 32 are fixedly connected to both the front and rear sides inside the equipment chamber 13. A positioning rod 33 is slidably connected inside the positioning cylinder 32. The upper end of the positioning rod 33 is fixedly connected to the lower surface of the adjusting plate 3.
[0039] In addition, before the substrate 14 is fed into the drying chamber 11, the telescopic rod in the hydraulic cylinder 31 retracts into the interior of the hydraulic cylinder 31. At this time, the adjusting plate 3 moves downward, and the adjusting plate 3 moves the connecting block 36 and the support roller 37 downward, increasing the distance between the support roller 37 and the feed roller 22. This facilitates the substrate 14 passing through the upper side of the support roller 37 during the feeding process. After the substrate 14 passes through, the hydraulic cylinder 31 pushes the adjusting plate 3 and the support roller 37 upward, thereby making the portion of the substrate 14 between the guide roller 23 and the support roller 37 adhere tightly to the lower surface of the guide plate 2, improving the drying effect on the surface of the substrate 14.
[0040] The working principle of this utility model is as follows: By cooperating with the feeding roller 22, the guide roller 23, the support roller 37 and the discharge roller 24, the substrate 14 is arranged in a Z-shape in the drying chamber 11. While slightly increasing the height of the drying chamber 1, the length of the substrate 14 inside the drying chamber 1 is greatly increased. At the same time, the heating plate 21, the guide plate 2, the first drying tube 43 and the second drying tube 45 work together to dry the substrate 14 inside the drying chamber 11, effectively improving the drying efficiency of the substrate 14.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
