Description

Technical Field

[0001] This utility model relates to the field of packaging and printing technology, specifically to an adjustable drying duct structure for packaging and printing. Background Technology

[0002] Packaging printing is the printing process that uses various packaging materials as a medium to print decorative patterns, designs, or text onto the packaging. This makes the product more attractive or informative, thereby conveying information and increasing sales. During the packaging printing process, to ensure the ink or coating on the printed materials slides quickly, thus guaranteeing printing quality and production efficiency, drying ducts are used to dry the printed materials.

[0003] In operation, the drying ductwork connects to the air intake pipes, allowing hot air from the drying system to enter the drying chamber and dry the printed materials. However, existing drying ductwork is inconvenient for adjusting the air intake volume according to the drying chamber's operating status, and it is also inconvenient for adjusting the air intake angle according to the printing position, thus compromising drying efficiency. Therefore, this paper proposes an adjustable drying ductwork structure for packaging printing to address these issues. Summary of the Invention

[0023] Please see Figure 1-5This utility model provides a technical solution: an adjustable drying duct structure for packaging printing, including a drying box 1. The drying box 1 has multiple hinges on its outer walls at both ends, and each hinge has a door. The drying box 1 has multiple drying ports 2 embedded in its upper part, and each drying port 2 has a first connecting pipe 3 above it. The other end of the first connecting pipe 3 is connected to a diversion pipe 5, and the diversion pipe 5 has a first air inlet pipe 6. The other end of the first air inlet pipe 6 is connected to the heating system of the dryer. The diversion pipe 5 has multiple air inlet valves 4. It should be noted that a fan is installed at the connection between the first connecting pipe 3 and the drying port 2, and a filter device is installed inside the first connecting pipe 3 to ensure that the drying port 2 can work normally. The drying box 1 is equipped with an air circulation device and a temperature monitoring device inside to ensure the temperature and air quality inside the drying box 1.

[0024] Furthermore, the diversion pipe 5 is connected to the drying machine heating system through the first air inlet pipe 6, and is connected to the drying port 2 through the first connecting pipe 3 and the air inlet valve 4. Thus, under the action of the air inlet valve 4, the number of drying ports 2 that need to be operated can be controlled according to the working status of the drying box 1, thereby ensuring the preheating efficiency of the drying box 1 while ensuring subsequent energy saving.

[0025] The drying oven 1 has fixed pipes 8 inserted on both sides, and the fixed pipes 8 are equipped with fans inside. The fixed pipes 8 are equipped with second air inlets 7 on the top, and the other end of the second air inlets 7 are connected to the heating system of the dryer. The fixed pipes 8 are equipped with fixed covers 11 at one end, and the fixed covers 11 are equipped with square fixing blocks on the upper and lower outer walls. The fixed pipes 8 are also equipped with square fixing blocks on the upper and lower outer walls. Bolts 12 are inserted through the fixing blocks, and nuts are screwed on the other end of the bolts 12. Screws 10 are screwed on the fixed covers 11, and the other end of the screws 10 is inserted through the perforated plate 9. The perforated plate 9 is equipped with a fixing frame on the outer wall, and the fixing frame is equipped with brushes 13 on the outer wall.

[0026] Furthermore, a spiral hole is provided on the fixed cover 11, and the hollow plate 9 forms a spiral locking structure with the fixed cover 11 through the screw 10. Thus, the fixed cover 11 installed by the screw facilitates the installation and removal of the hollow plate 9 assembly, so that hot air can be filtered through the hollow plate 9, and the inner wall of the fixed tube 8 can be cleaned periodically by the brush 13.

[0027] One end of the fixed pipe 8 is provided with a second connecting pipe 14 inside the drying chamber 1, and the other end of the second connecting pipe 14 is connected to the air inlet 17. The drying chamber 1 is provided with servo motors 15 on both inner walls, and one end of the output shaft of the servo motor 15 is connected to the rotating shaft 16 through a coupling. The rotating shaft 16 is provided with a connecting plate on the outer wall, and the other end of the connecting plate is connected to the air inlet 17. It should be noted that multiple sets of electrical equipment in this device are connected to the power supply equipment through power lines, and the working status of the electrical equipment is monitored through corresponding sensors, controllers and other equipment to ensure that the electrical equipment in this device can perform normal control work.

[0028] Furthermore, the second air inlet pipe 7 forms a communication structure with the air inlet 17 through the fan, the perforated plate 9, and the second connecting pipe 14, so that the printing area on the packaging can be directly dried through multiple sets of air inlets 17, further ensuring the drying efficiency of the printed products.

[0029] Furthermore, under the action of the servo motor 15, the air inlet 17 forms a rotating structure in the drying chamber 1 via the rotating shaft 16, thereby the angle of the air inlet 17 can be adjusted by the servo motor 15 assembly to ensure that the air inlet 17 is directly facing the printing area for drying.

[0030] Working Principle: Using an adjustable drying duct structure for packaging printing, heated air is first introduced into the distribution pipe 5 through the first air inlet pipe 6, and then distributed to different first connecting pipes 3 through the distribution pipe 5. This allows for initial heating of the drying chamber 1 through multiple drying ports 2, thereby increasing the air intake volume inside the drying chamber 1 and ensuring the preheating efficiency of the drying chamber 1. After preheating is completed inside the drying chamber 1, the number of opening drying ports 2 can be controlled by the air inlet valve 4 to ensure energy efficiency and prevent excessive air intake from causing the internal temperature of the drying chamber 1 to be too high, which would affect the drying effect of the printed packaging products. Subsequently, the printed products to be dried can be placed inside the drying chamber 1, and the heated air in the second air inlet pipe 7 can be introduced into the fixed pipe 8 by the fan inside the fixed pipe 8. The air enters the fixed tube 8 and then the second connecting tube 14 through the hollow plate 9 inside the fixed tube 8, so that the printed products can be directly dried through the air inlet 17. At the same time, the servo motor 15 can be started. The output shaft of the servo motor 15 drives the rotating shaft 16 to rotate through the coupling, so that the angle of the air inlet 17 can be adjusted by the rotating shaft 16, thereby ensuring that the air inlet is directly facing the printed area on the packaging for drying, further ensuring the drying efficiency of the device for the printed products. After the device is used, the bolts 10 and nuts can be rotated to remove the fixed cover 11 for disassembly. At the same time, the inner wall of the fixed tube 8 can be cleaned by the brush 13 on the outside of the hollow plate 9, so as to facilitate the regular maintenance of the cleanliness of the inside of the fixed tube 8. This is the usage process of the adjustable drying air duct structure for packaging printing.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
