Abstract

This utility model discloses a surface drying treatment device for printed materials, belonging to the field of printing. It includes a device frame with a conveyor belt for transporting printed materials fixedly connected inside. A fan is installed at the top of the inner cavity of the device frame. A guide frame is located directly below the exhaust port of the heating plate, with a flow channel. A baffle plate is adapted to and slidably connected to the flow channel.

Description

Technical Field

[0001] This utility model belongs to the field of printing technology, and specifically relates to a surface drying treatment device for printed materials. Background Technology

[0002] Printing, a common method in the printing industry, works by first making a printing plate from the text and images to be printed, mounting it on a printing press, and then applying ink, either manually or by the printing press, to the areas on the printing plate containing the text and images. The ink is then transferred directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics) to reproduce a printed product identical to the printing plate.

[0003] For example, CN216101032U discloses a curing and drying device for printed materials, relating to the field of printing technology. It includes a main body, a main support frame, a fixed power chamber, a drying and curing box, and an insulated door panel. The main support frame is fixedly installed on the left and right sides of the bottom of the main body, and the fixed power chamber is located on the bottom of the main body and inside the main support frame. The drying and curing box is fixedly installed on the top of the main body, and an insulated door panel is movably installed on one side of the drying and curing box. This invention solves the problem that existing printed materials require long periods of placement for curing and drying during production, resulting in excessive time consumption, by incorporating a lamp connecting platform and an ultraviolet drying lamp. Through the combination of these structures, the printed materials can be quickly baked by the drying lamp during production, allowing for rapid curing and drying in a short time, reducing time consumption.

[0004] In practical use, when printed materials are heated and dried, the ink or dye on their surface will evaporate into vapor. This vapor, under the influence of hot airflow, easily diffuses and directly contacts and adheres to the outer surface of heating components (such as heating tubes, lamps, or hot air nozzles). The components in the vapor may char, scale, or corrode under high-temperature conditions, significantly reducing heating efficiency, increasing energy consumption, shortening the lifespan of the heating components, and even causing equipment malfunctions or safety hazards due to localized overheating or contamination. Furthermore, the vapor condensing and dripping inside the device may also cause secondary contamination of the printed materials. Therefore, this invention provides a surface drying treatment device for printed materials. Utility Model Content

[0005] The purpose of this invention is to provide a surface drying treatment device for printed materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface drying treatment device for printed materials, comprising a device frame, a conveyor belt for conveying printed materials is fixedly connected inside the device frame, a fan is provided at the top of the inner cavity of the device frame, a heating plate is provided at the bottom of the fan, a guide frame is fixedly connected at the bottom of the discharge end of the heating plate, and a baffle plate is slidably connected inside the guide frame.

[0007] In a preferred embodiment, the guide frame is provided with a flow groove directly below the exhaust port of the heating plate, and the outside of the baffle plate is adapted to the inside of the flow groove.

[0008] In a preferred embodiment, the baffle plate has a recess on the side facing the exhaust port of the heating plate, and inclined guide holes are provided on both sides of the recess. When the baffle plate is located inside the flow channel, the discharge ends of the two inclined guide holes are in contact with the inner wall of the flow channel.

[0009] In a preferred embodiment, guide posts are fixedly connected to both sides of the top of the guide frame cavity, and a connecting plate is fixedly connected to the bottom of each guide post. Both ends of the baffle plate are provided with sliding parts that are slidably connected to the outside of the guide posts.

[0010] In a preferred embodiment, a spring sleeved on the outside of the guide post is fixedly connected between the bottom of the sliding part and the top of the connecting plate.

[0011] In a preferred embodiment, the top of the guide frame cavity is provided with guide plates on both sides of the baffle plate, and when the baffle plate moves down, the two inclined guide holes face the two guide plates respectively.

[0012] In a preferred embodiment, mounting parts are fixedly connected to the four corners of the top of the guide frame, and a preheating lamp plate is provided on one side of the guide frame at the top of the inner cavity of the device frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The surface drying device for printed materials has a guide frame located directly below the exhaust port of the heating plate with a flow channel. The baffle plate is adapted to the flow channel and can be slidably connected. During the drying process, the baffle plate can prevent the hot air flow discharged from the heating plate from rushing upwards directly, changing the direction of the steam and hot air flow, making it difficult for the steam to directly contact the heating components. This greatly reduces the coking, scaling or corrosion of the heating components by the components in the steam under high temperature environment, thereby maintaining the good performance of the heating components, improving heating efficiency, reducing energy consumption, extending the service life of the heating components, and reducing equipment failures and safety hazards caused by damage to the heating components.

[0015] The surface drying treatment device for printed materials has a recessed part on the side of the baffle plate facing the exhaust port of the heating plate, and inclined guide holes on both sides. When the baffle plate is located inside the flow channel, the discharge end of the inclined guide hole is in contact with the inner wall of the flow channel. This design allows the hot air and steam to flow along a specific path when passing through the baffle plate, further optimizing the steam guiding effect and ensuring that the steam does not diffuse randomly to the surface of the heating component, thus enhancing the protection of the heating component.

[0016] This surface drying device for printed materials has guide plates located on both sides of the baffle plate at the top of the inner cavity of the guide frame. When the baffle plate moves down, two inclined guide holes face the two guide plates respectively. After passing through the baffle plate and the inclined guide holes, the steam is guided to a specific area of ​​the device by the guide plates, instead of spreading and condensing randomly inside the device. This effectively avoids the steam from dripping onto the printed materials after condensation, causing secondary pollution, and ensures the drying quality and use effect of the printed materials.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4This utility model provides a surface drying treatment device for printed materials, including a device frame 1. A conveyor belt 2 for conveying printed materials is fixedly connected inside the device frame 1. A fan 3 is provided at the top of the inner cavity of the device frame 1. A heating plate 5 is provided at the bottom of the fan 3. A guide frame 6 is fixedly connected at the bottom of the discharge end of the heating plate 5. A baffle plate 7 is slidably connected inside the guide frame 6. Mounting parts 606 are fixedly connected at the four corners of the top of the guide frame 6. A preheating lamp plate 4 is provided on one side of the guide frame 6 at the top of the inner cavity of the device frame 1.

[0025] The printed material is placed on the conveyor belt 2, which starts running and smoothly transports the printed material into the device. As the printed material gradually approaches the preheating lamp plate 4, the preheating lamp plate 4 emits heat to preheat the printed material. The preheating process causes the surface temperature of the printed material to rise slowly, which causes some of the moisture in the ink or dye to begin to evaporate, preparing for subsequent rapid drying. At the same time, it also helps to make the overall temperature of the printed material more uniform and avoids uneven drying caused by excessive local temperature differences.

[0026] In this embodiment, the guide frame 6 is provided with a flow groove 604 directly below the exhaust port of the heating plate 5. The outer side of the baffle plate 7 is adapted to the inner side of the flow groove 604. A recess 702 is provided on the side of the baffle plate 7 facing the exhaust port of the heating plate 5. Inclined guide holes 703 are provided on both sides of the recess 702. When the baffle plate 7 is located inside the flow groove 604, the discharge ends of the two inclined guide holes 703 are in contact with the inner wall of the flow groove 604. Both sides of the top of the inner cavity of the guide frame 6 are fixedly connected. There are guide posts 602, and a connecting plate 601 is fixedly connected to the bottom end of each guide post 602. Both ends of the baffle plate 7 are provided with sliding parts 701 that are slidably connected to the outside of the guide post 602. A spring 603 sleeved on the outside of the guide post 602 is fixedly connected between the bottom of the sliding part 701 and the top of the connecting plate 601. The top of the inner cavity of the guide frame 6 is provided with guide plates 605 on both sides of the baffle plate 7. When the baffle plate 7 moves down, the two inclined guide holes 703 are respectively facing the two guide plates 605.

[0027] When the fan 3 starts working, it generates airflow. The airflow flows downward and is heated when it passes the heating plate 5, forming high-temperature hot air. The high-temperature hot air is discharged from the exhaust port of the heating plate 5 and directly impacts the baffle plate 7. Since the guide frame 6 is located directly below the exhaust port of the heating plate 5 and has a flow groove 604, and the outside of the baffle plate 7 is adapted to the inside of the flow groove 604, the baffle plate 7 can move to a certain extent within the flow groove 604 and play a preliminary blocking and guiding role for the hot air. The side of the baffle plate 7 facing the exhaust port of the heating plate 5 has a recess 702, and inclined guide holes 703 are provided on both sides of the recess 702.

[0028] When hot air impacts the baffle plate 7, some of the hot air enters the recess 702 and is then discharged through the inclined guide holes 703. Since the baffle plate 7 is located inside the flow channel 604, the discharge ends of the two inclined guide holes 703 are in contact with the inner wall of the flow channel 604. This allows the hot air discharged from the inclined guide holes 703 to flow along the inner wall of the flow channel 604, further changing the direction of the hot air flow. At the same time, the top of the inner cavity of the guide frame 6 is provided with guide plates 605 on both sides of the baffle plate 7. When the baffle plate 7 moves downward under the action of hot air pressure and other factors, the two inclined guide holes 703 are respectively facing the two guide plates 605. Under the guidance of the guide plates 605, the hot air flows more precisely to the surface of the printed matter that needs to be dried, ensuring that the hot air can evenly cover the printed matter and improve the drying effect.

[0029] The baffle plate 7 has sliding parts 701 at both ends that are slidably connected to the outside of the guide post 602. A spring 603 sleeved on the outside of the guide post 602 is fixedly connected between the bottom of the sliding part 701 and the top of the connecting plate 601. When the hot air pressure changes, the baffle plate 7 will slide up and down along the guide post 602. The spring 603 plays the role of buffering and resetting. When the force disappears, the spring 603 will make the baffle plate 7 return to the initial position, ensuring that the baffle plate 7 can continuously and stably guide the hot air, so that the entire drying device can work stably for a long time.

[0030] The preheating plate 4 preheats the printed material in advance, raising the surface temperature and causing moisture to evaporate, thus shortening the drying time under the action of high-temperature hot air. The combination of the baffle plate 7, the inclined guide hole 703 and the guide plate 605 can accurately guide the hot air to the surface of the printed material, so that the hot air can evenly cover the printed material, avoiding disorderly diffusion and waste of hot air, improving the utilization rate of heat energy, and thus significantly improving the drying efficiency.

[0031] The baffle 7 prevents the hot air discharged from the heating plate 5 from rushing upwards directly, changing the direction of steam and hot air flow. This makes it difficult for steam to directly contact the heating components (such as heating tubes, lamps, etc.), reducing the coking, scaling, or corrosion of the heating components by the components in the steam under high temperature conditions. This maintains the good performance of the heating components, extends the service life of the heating components, and reduces the maintenance cost of the equipment.

[0032] This design avoids the random diffusion and condensation of steam inside the device, which could drip onto the printed materials and cause secondary pollution. It ensures the drying quality and usability of the printed materials. The uniform hot air distribution ensures that the surface of the printed materials is heated evenly, avoiding problems such as deformation and color differences caused by local overheating or uneven drying. This improves the overall quality of the printed materials. The design of the guide column 602, the sliding part 701, and the spring 603 allows the baffle plate 7 to slide stably up and down under the guidance of the guide column 602 and to be reset by the spring 603. This ensures that the baffle plate 7 can accurately return to the appropriate position under different working conditions, thus ensuring the operational stability and reliability of the entire device.

[0033] The design of the mounting section 606 facilitates the installation and disassembly of the guide frame 6, makes it easier to maintain and repair the device, and improves the maintainability of the device.

[0034] The working principle and usage process of this utility model are as follows: First, the printed material is placed on the conveyor belt 2 and smoothly transported into the device. When it approaches the preheating lamp plate 4, the preheating lamp plate 4 heats up to preheat the printed material, raising the surface temperature and evaporating some moisture, preparing for rapid drying. This also ensures that the overall temperature of the printed material is uniform, avoiding uneven drying. The fan 3 generates airflow, which is heated into high-temperature hot air by the heating plate 5 and discharged from the exhaust port, impacting the baffle plate 7. The guide frame 6 has a flow groove 604 below the exhaust port, which is adapted to the baffle plate 7 to initially block and guide the hot air. The baffle plate 7 has a recess 702 on the side facing the exhaust port and inclined guide holes 703 on both sides. When hot air impacts, some of it enters the recessed part 702 and is discharged through the inclined guide hole 703. The discharge end is in contact with the inner wall of the flow channel 604, changing the direction of the hot air flow. When the baffle plate 7 moves down, the inclined guide hole 703 faces the guide plate 605. Under the guidance of the guide plate 605, the hot air accurately and evenly covers the printed matter, improving the drying effect. The baffle plate 7 has sliding parts 701 at both ends that connect to the guide column 602. There is a spring 603 between the sliding part 701 and the connecting plate 601. When the hot air pressure changes or is subjected to other forces, the baffle plate 7 slides along the guide column 602, and the spring 603 buffers and resets, ensuring that the baffle plate 7 continues to guide stably, so that the device can work stably for a long time.

[0035] It should be noted that the conveyor belt 2 (YD-WB series high temperature resistant mesh belt conveyor), fan 3 (SF type low noise axial flow fan), heating plate 5 (medium wave infrared lamp tube), as well as the control unit and wiring connection involved, are all existing public technologies, so they are not described in detail.
