Description

Technical Field

[0001] This utility model relates to the field of printing material drying technology, and in particular to a printing material drying device for the printing industry. Background Technology

[0002] In the printing industry, drying of printed materials is a crucial step determining print quality and production efficiency. With continuous innovation in printing technology and increasingly demanding market requirements for print quality, drying equipment plays an increasingly important role in the entire printing production process. From the initial simple natural drying to the widely used hot air drying today, the types of drying equipment have become increasingly diverse, and their functions have become increasingly powerful. To enhance their competitiveness, printing companies urgently need equipment capable of quickly, efficiently, and precisely drying printed materials to meet the needs of large-scale production and diverse printing requirements.

[0003] Currently, the most commonly used drying equipment in the printing industry employs hot air drying technology. Its principle involves heating air using heating elements, then using a fan to deliver the hot air to the drying area. The hot air makes full contact with the surface of the printed material, causing the moisture in the material to evaporate rapidly, thus achieving drying. In terms of mechanical structure, drying equipment typically includes a heating system, a ventilation system, and a material conveying system. The heating system consists of heating elements and a temperature control device, which can precisely control the temperature of the hot air; the ventilation system distributes the hot air evenly throughout the drying area through air ducts and outlets; and the material conveying system uses rollers or belts to move the printed material through the drying area at a uniform speed.

[0004] In practical use, fogging of the observation window causes significant problems for operators. The high internal temperature of the drying unit, coupled with a large temperature difference between the internal and external environments, makes the observation window surface prone to fogging. Once fogged, operators cannot clearly observe the drying process inside the unit, making it difficult to quickly detect equipment malfunctions, such as damaged heating elements or blocked ventilation systems. To check the internal conditions, operators must frequently open the equipment, leading to significant heat leakage, energy waste, increased production costs, and dust entering the drying unit, contaminating printed materials, reducing print quality, and severely impacting the efficiency and quality of the drying process. Therefore, this paper proposes a printing material drying device for the printing industry to address these issues. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a drying device for printed materials in the printing industry, which aims to improve the problem of fogging in the observation window in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying device for printed materials in the printing industry includes a drying box, an observation window with a cleaning component, a pressing component inside the drying box, a support frame fixedly connected to the bottom of the drying box, a motor fixedly connected to the outer wall of the support frame, and a conveyor belt fixedly connected to the output end of the motor.

[0008] The cleaning assembly includes a motor and a scraper. The output end of the motor is fixedly connected to a connecting block 1. A rotating rod is rotatably connected to the inner wall of the connecting block 1. A connecting arm is rotatably connected to the other end of the rotating rod. A rotating shaft is rotatably connected to the other end of the connecting arm. A push rod is fixedly connected to the outer wall of the rotating shaft. A fixing block 1 is fixedly connected to the inner wall of the drying chamber. The outer wall of the push rod is slidably connected to the inside of the fixing block 1. The other end of the push rod is fixedly connected to the outer wall of the scraper. The scraper slides on the surface of the observation window.

[0009] As a further description of the above technical solution:

[0010] The pressing assembly includes a second fixing block and a pressure roller. The outer wall of the second fixing block is fixedly connected to the outer wall of the drying oven, and a stud is rotatably connected to the inner wall of the second fixing block. A rubber block is fixedly connected to the bottom of the stud.

[0011] As a further description of the above technical solution:

[0012] A manual push rod is slidably connected to the inner wall of the drying oven. One end of the manual push rod is fixedly connected to a connecting block two, and two connecting blocks three are rotatably connected to the bottom of the connecting block two.

[0013] As a further description of the above technical solution:

[0014] The other end of the connecting block three is rotatably connected to the connecting frame one. The top of the connecting frame one is fixedly connected to a sliding block. The top of the drying box is fixedly connected to a slide rail. The inner wall of the sliding block is slidably connected to the outer wall of the slide rail.

[0015] As a further description of the above technical solution:

[0016] The bottom of the connecting frame is fixedly connected to multiple connecting pipes, and the inner wall of the connecting pipes is slidably connected to connecting pipes.

[0017] As a further description of the above technical solution:

[0018] A spring is installed inside the first connecting pipe. One end of the spring is fixedly connected to the inner wall of the top of the first connecting pipe, and the other end of the spring is fixedly connected to the top of the second connecting pipe.

[0019] As a further description of the above technical solution:

[0020] The bottom of the second connecting pipe is fixedly connected to the second connecting frame, and the bottom of the second connecting frame is fixedly connected to the top of the pressure roller.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, when observing through the observation window, the motor drives the connecting block to rotate. The rotation of the connecting block drives the push rod, which in turn drives the scraper to wipe the surface of the observation window, achieving the effect of removing surface water mist. This avoids fogging of the observation window due to excessive temperature difference between the inside and outside, which would prevent the observation of the internal dryness from being checked. This speeds up the fault detection process, facilitates timely maintenance measures, effectively solves the problem of heat leakage and dust entry caused by frequent equipment opening, and improves work efficiency.

[0023] In this invention, when the paper passes through the pressure rollers, the pressure rollers compress the springs upwards to accommodate papers of different thicknesses. Then, the spring force presses the paper down. By pulling the manual push rod, the connecting frame is driven, and the connecting frame drives the sliding block to slide on the outer wall of the slide rail for adjustment. This achieves the pressing of the paper during the drying process and can also adjust the distance between the pressure rollers to accommodate papers of different sizes. This prevents the paper from curling due to uneven moisture distribution and fiber shrinkage during the drying process, thus improving the stability of the operation. Attached Figure Description

[0033] The cleaning assembly includes a motor 6 and a scraper 13. A connecting block 7 is fixedly connected to the output end of the motor 6. The motor rotates to drive the connecting block 7 to rotate. A rotating rod 8 is rotatably connected to the inner wall of the connecting block 7. A connecting arm 9 is rotatably connected to the other end of the rotating rod 8. A rotating shaft 10 is rotatably connected to the other end of the connecting arm 9. A push rod 11 is fixedly connected to the outer wall of the rotating shaft 10. A fixing block 12 is fixedly connected to the inner wall of the drying chamber 1. The outer wall of the push rod 11 is slidably connected to the inside of the fixing block 12. The other end of the push rod 11 is fixedly connected to the outer wall of the scraper 13. The scraper 13 is made of rubber, which is soft and has good scraping performance. It can effectively remove stains on the surface without damaging the glass surface of the observation window 2 and slide smoothly on the surface of the observation window 2.

[0034] Reference Figure 1 , Figure 4 and Figure 5The pressing assembly includes a second fixing block 25 and a pressure roller 24. The outer wall of the second fixing block 25 is fixedly connected to the outer wall of the drying oven 1. A stud 26 is rotatably connected to the inner wall of the second fixing block 25. A rubber block 27 is fixedly connected to the bottom of the stud 26. The rubber block 27 is made of silicone rubber, which is soft and has good anti-slip properties and cushioning effect. When it is necessary to fix the manual push rod 14, the operator rotates the stud 26 clockwise. The stud 26 moves downward on the inner wall of the second fixing block 25 with the help of the thread, thereby driving the rubber block 27 to press the manual push rod 14 downward, achieving the fixing effect. Conversely, when it is necessary to release the fixation, the operator turns the stud 26 counterclockwise. The stud 26 rotates upward, causing the rubber block 27 to move away from the manual push rod 14, thereby releasing the compression fixation. The manual push rod 14 is slidably connected to the inner wall of the drying chamber 1. One end of the manual push rod 14 is fixedly connected to a connecting block 2 15. The bottom of the connecting block 2 15 is rotatably connected to two connecting blocks 3 16. The other end of the connecting block 3 16 is rotatably connected to a connecting frame 17. By pulling the manual push rod 14 outward, the two connecting blocks 3 16 pull the connecting frame 17. The top of the connecting frame 17 is fixedly connected to a sliding block 18. The top of the drying chamber 1 is fixedly connected to a slide rail 19. The inner wall of the sliding block 18 is slidably connected to the outer wall of the slide rail 19. The sliding block 18 slides on the slide rail 19. The outer wall of the slide rail 19 achieves the effect of adjusting the distance between the two connecting brackets 17. Multiple connecting tubes 20 are fixedly connected to the bottom of the connecting brackets 17. The connecting tubes 20 are distributed at the bottom of the connecting brackets 17. Connecting tube 21 is slidably connected to the inner wall of the connecting tube 20. A spring 22 is installed inside the connecting tube 20. One end of the spring 22 is fixedly connected to the top inner wall of the connecting tube 20, and the other end of the spring 22 is fixedly connected to the top of the connecting tube 21. Connecting bracket 23 is fixedly connected to the bottom of the connecting tube 21. The bottom of the connecting bracket 23 is fixedly connected to the top of the pressure roller 24. The wheel body of the pressure roller 24 is made of rubber. This rubber has good elasticity and friction, and can apply uniform pressure to the printed material without damaging the surface of the printed material.

[0035] Working principle: When the observation window 2 fogs up to observe the internal dryness, the motor 6 is turned on, which drives the connecting block 7 to rotate. The rotation of the connecting block 7 drives the rotating rod 8 to rotate, which in turn drives the connecting arm 9 to move. The movement of the connecting arm 9 drives the rotating shaft 10 to move, which in turn drives the push rod 11 to move. The movement of the push rod 11 drives the scraper 13 to move, thus cleaning the outer wall of the observation window 2 to prevent fogging caused by a large temperature difference between the inside and outside, which would prevent the interior of the drying oven 1 from being observed.

[0036] During the paper drying process, pushing the manual push rod 14 moves the connecting block 2 15, which in turn moves the connecting blocks 3 16 on both sides. The connecting blocks 3 16 then move the connecting frames 17 on both sides, which in turn move the sliding block 18. The sliding block 18 then slides on the outer wall of the slide rail 19 to adjust the distance between the two connecting frames 17. The movement of the connecting frames 17 then moves the connecting tube 20, which in turn moves the connecting tube 21. The movement of the connecting tube 21 then moves the connecting frame 23, which in turn moves the pressure roller 24. When the appropriate distance is reached, the stud 26 is rotated clockwise. The stud 26, aided by its threads, gradually moves downwards along the inner wall of the fixing block 25, causing the rubber block 27 to press down on the manual push rod 14, achieving a fixing effect. Conversely, when it is necessary to release the fixation, simply turn the stud 26 counterclockwise. The stud 26 rotates upward, causing the rubber block 27 to move away from the manual push rod 14, thereby releasing the pressure fixation. When the paper passes the pressure roller 24, the paper first pushes up the pressure roller 24, then the pressure roller 24 moves upward, causing the connecting frame 23 to move. Then, the movement of the connecting frame 23 causes the connecting tube 21 to move, and then the movement of the connecting tube 21 compresses the spring 22 to achieve the purpose of pressing the paper.

[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.
