[0002] With the development of the packaging industry, packaging box ink printing technology is constantly being innovated to meet the needs of protecting, beautifying and conveying information about goods. Ink printing uses various packaging materials as carriers to print decorative patterns on packaging boxes to beautify goods and convey information, thereby improving the market competitiveness of goods. However, it should be noted that water-based inks have a relatively slow drying speed during the drying process, which leads to unstable printing quality. A surface drying device for printing and packaging is now used to dry the ink.

[0003] However, existing surface drying devices for printing and packaging cannot detect the internal temperature of the drying device in real time, cannot reduce the internal temperature of the drying device according to the needs, and have poor heat dissipation. Internal heat accumulation will affect the normal use of the conveyor belt structure. Utility Model Content

A rubber plug is fixedly connected to one end of the fixing block, and a fixing plate is fixedly connected to the other end of the fixing block. An infrared heating tube is fixedly installed inside the fixing plate.

[0007] Preferably, the limiting plate has a movable hole inside, and the outer surface of the movable rod is movably connected to the inside of the movable hole, with the center of the movable hole and the center of the movable rod on the same horizontal line.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1: This utility model provides a surface drying device for printing and packaging, such as... Figures 1 to 5 As shown, the system includes a frame body 1, inside which a conveyor belt structure 2 is installed. The conveyor belt structure 2 consists of a belt body, a tensioning device, and a drive device. Multiple exhaust fans 3 are fixedly installed at the top of the frame body 1. A drying structure 4 is fixedly installed inside the frame body 1. The drying structure 4 consists of an electric heating element, a circulation system, and an insulation layer, which are the main components of a common drying structure on the market and will not be described in detail here. A control panel 5 is fixedly installed on the outer surface of the frame body 1 near the drying structure 4. The control panel 5 is electrically connected to the drying structure 4 to achieve temperature control. One end of the control panel 5 is fixedly installed... A temperature control probe is fixedly connected inside the frame body 1, which can monitor the temperature inside the frame body 1 in real time. The above are all existing technologies and will not be described in detail here. Louvered doors 6 are movably connected inside both ends of the frame body 1. One end of the louvered door 6 is fixedly connected to an electric telescopic rod 7, which is fixedly installed inside the frame body 1. A movable rod 8 is fixedly connected to the other end of the louvered door 6 at the position outside the electric telescopic rod 7. A limit plate 9 is movably connected to the outer surface of the movable rod 8, which is fixedly connected inside the frame body 1. A cylinder 10 is fixedly connected to one end of the movable rod 8.

[0022] like Figure 1 and Figure 5 As shown, a fixing groove 11 is provided inside one end of the frame body 1 at the position above the conveyor belt structure 2. A fixing block 12 is snapped into the fixing groove 11 inside the frame body 1. A rubber plug 13 is fixedly connected to one end of the fixing block 12, and a fixing plate 14 is fixedly connected to the other end of the fixing block 12. An infrared heating tube 15 is fixedly installed inside the fixing plate 14. This simplifies the installation process of the fixing plate 14 and allows for preliminary preheating of printed materials passing under the infrared heating tube 15, so that the printed materials can be dried more evenly and thoroughly in the subsequent drying process, effectively improving the drying efficiency of the printed materials.

[0023] like Figure 1 and Figure 2 As shown, the limiting plate 9 has a movable hole inside, and the outer surface of the movable rod 8 is movably connected to the inside of the movable hole. The center of the movable hole and the center of the movable rod 8 are on the same horizontal line, ensuring that the movable rod 8 can make stable linear movement inside the limiting plate 9 under the drive of the electric telescopic rod 7, realizing the precise movement of the louvered door 6 and improving the stability of the louvered door 6 when it moves.

[0024] like Figure 1 and Figure 2As shown, the radius of the movable hole is equal to the radius of the movable rod 8, the radius of the cylinder 10 is greater than the radius of the movable hole, one end face of the cylinder 10 is in contact with one end face of the limiting plate 9, and the cylinder 10 plays the role of limiting the louver door 6.

[0025] like Figure 1 and Figure 2 As shown, a rubber sheet is attached to one end of the louvered door 6 at the position corresponding to the limiting plate 9. This sheet protects the louvered door 6 and prevents it from colliding directly with the limiting plate 9 when driven by the electric telescopic rod 7, thus preventing damage to the louvered door 6 and improving its safety and service life.

[0026] like Figure 1 and Figure 5 As shown, the surface area of ​​the rubber plug 13 near the fixing block 12 is larger than that of the other end. The end of the rubber plug 13 away from the fixing block 12 has an inclined surface. The inclined surface facilitates the smooth insertion of the rubber plug 13 into the fixing groove 11. Furthermore, the rubber can improve the connection stability between the fixing block 12 and the fixing groove 11 after being squeezed.

[0027] Working principle: In actual use, the device first removes the fixing plate 14, aligning the fixing block 12 with the fixing groove 11. Then, the fixing plate 14 is moved towards the fixing groove 11. The movement of the fixing plate 14 drives the fixing block 12 to move synchronously, and the movement of the fixing block 12 drives the rubber plug 13 to move synchronously. As the fixing plate 14 moves, the inclined surface of the rubber plug 13 will first contact the fixing groove 11, and then smoothly enter the interior of the fixing groove 11 along the inclined surface. When the fixing block 12 is fully engaged in the interior of the fixing groove 11, the fixing plate 14 is fixed. The conveyor belt structure 2, exhaust fan 3, drying structure 4, and infrared heating tube 15 are then activated. The printed materials that need to be dried are placed on the surface of the conveyor belt, and then the conveyor belt moves the printed materials. When the printed materials pass under the infrared heating tube 15, they can be preheated, so that the printed materials can be dried more evenly and thoroughly in the subsequent drying process, effectively improving the drying efficiency of the printed materials.

[0028] The printed materials, after initial preheating, continue to move into the frame body 1. The heat generated by the electric heating tube in the drying structure 4 is evenly distributed through the circulation system, efficiently and quickly drying the printed materials. This allows the ink on the surface of the printed materials to achieve the desired drying effect in a short time. After prolonged use, when the control panel 5 detects that the internal temperature of the frame body 1 is too high, it activates the electric telescopic rod 7. The electric telescopic rod 7 moves the louvered door 6, which in turn moves the movable rod 8 synchronously. The movable rod 8 then moves the cylinder 10 synchronously. When the cylinder 10 contacts the limit plate 9, the louvered door 6 completes its movement and opens, allowing internal air circulation. This air circulation effectively removes internal heat. The system can monitor the internal temperature of the frame body 1 in real time and improve internal heat dissipation efficiency as needed, preventing excessive internal temperature from affecting the normal operation of the conveyor belt structure 2 and effectively extending its service life.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
