Description

Technical Field

[0001] This utility model relates to the field of rapid ink drying technology, specifically a rapid ink drying device for a cardboard printing machine. Background Technology

[0002] In the cardboard printing industry, ink drying has always been a key factor affecting production efficiency and product quality. Traditional drying methods, whether air drying or basic hot air drying, have many drawbacks. Air drying is too time-consuming, making it difficult to meet the needs of large-scale production, and is easily affected by environmental factors; ordinary hot air drying is not only inefficient, but also often results in uneven heat distribution, leading to inconsistent ink drying levels, which seriously affects the appearance and quality of printed products.

[0003] To avoid such situations, Chinese patent application number 202022397568.5 discloses a rapid ink drying device for cardboard printing machines. This patent includes a box body with a protective cover fixedly installed inside. A dryer is installed inside the protective cover. A drive motor is installed at the bottom of the box body, and a rotating shaft is connected to the top of the drive motor. One end of the rotating shaft is connected to a turntable, which contains an electric heating element. A fixture is fixedly installed on the top of the turntable. A ventilation opening is provided at the top of the box body, containing a dustproof net. An exhaust fan is located above the dustproof net and connected to an upper support frame. Compared with existing drying devices, this patent uses a multi-faceted heating method to make the ink drying more uniform. The entire oven contains two heating devices—a dryer and a resistance heating element—that simultaneously heat the ink, ensuring even heating on both sides. The turntable allows the ink to rotate continuously during the heating process, preventing overheating of any part and better protecting the items to be heated.

[0004] Although the aforementioned patent employs multi-faceted heating methods to achieve more uniform ink drying, with both a dryer and a resistance heating element inside the oven simultaneously heating the ink to ensure even heating on both sides, and a turntable that allows the ink to rotate continuously during heating to prevent overheating of any part and better protect the items to be heated, in actual use, because the patent uses a heating device within the oven body, each time cardboard is heated, the oven door must be opened, the cardboard placed in the designated position, and then the device must be activated for heating. After heating is complete, the oven door can only be opened and the cardboard removed after the internal temperature of the heating device has dropped to a suitable level (to avoid burns to the staff). The entire operation process is rather cumbersome, and the number of cardboard pieces dried each time is very limited, which reduces drying efficiency to some extent and is therefore not conducive to use by staff.

[0005] Therefore, there is a need for a rapid ink drying device for cardboard printing machines to solve the above-mentioned problems. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a rapid ink drying device for cardboard printing machines, which has the advantages of simultaneous heating from both top and bottom, accelerating the drying speed of ink, and improving drying efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides a rapid ink drying device for a cardboard printing machine, including a conveyor 1. The conveyor 1 has a main drive roller and a driven roller inside, both driven by a stepper motor. The surfaces of both the main and driven rollers are provided with anti-slip textures to increase the friction between the rollers and the cardboard, ensuring the stability of the cardboard during transport. Several ventilation openings 2 are symmetrically arranged on both sides of the conveyor 1. Diverters 3 are symmetrically fixedly connected to both sides of the conveyor 1, with each output end of the diverter 3 corresponding to and connected to one of the ventilation openings 2. A connecting frame 4 is fixedly connected to the bottom of the conveyor 1. The top of both sides of the connecting frame 4 is symmetrically connected to ventilation channels 5, and the other end of the ventilation channel 5 is connected to the input port of the distributor 3. The heating pipe 6 and the fan 7 are fixedly connected from top to bottom inside the connecting frame 4, and the heating pipe 6 is located below the ventilation channel 5. The top of the conveyor 1 is fixedly connected to the heating box 8. The heating box 8 has a heating cavity 9 inside, and the heating cavity 9 is equipped with an insulation liner. The insulation liner can reduce heat loss, thereby achieving energy saving to a certain extent. The heating box 8 has flow ports 10 on both sides. The heating frame 11 is symmetrically fixedly connected inside the heating cavity 9. The quantum infrared heating lamp 12 and the curing lamp tube 13 are fixedly connected inside the two heating frames 11 respectively.

[0024] refer to Figure 1 and Figure 5 The top of the heating box 8 is symmetrically connected to an exhaust pipe, and the top of the two exhaust pipes are connected to the same purification box 14. The front of the purification box 14 has a sliding opening, and an activated carbon plate 15 is slidably connected inside the sliding opening. An ultraviolet lamp tube 16 is fixedly connected inside the purification box 14, and the ultraviolet lamp tube 16 is located above the sliding opening. The top of the purification box 14 is fixedly connected to a top cover 17.

[0025] As a technical optimization of this utility model, by setting up the purification box 14, activated carbon plate 15 and ultraviolet lamp 16, the organic waste gas, such as formaldehyde, benzene and other volatile organic compounds, generated during the ink drying process can be adsorbed first. Then, the waste gas is oxidized and decomposed to remove benzene, ammonia and other organic compounds. It can also efficiently remove air pollutants such as CO, SO2, NO and hydrocarbons, thereby achieving the effect of efficient filtration and purification of waste gas.

[0026] refer to Figure 5 The top of the heating frame 11 has several ventilation holes 18, which are evenly arranged. The interior of the purification box 14 and the top cover 17 are both coated with a nano-photocatalyst coating.

[0027] As a technical optimization of this utility model, the ventilation hole 18 can improve the air circulation in the heating frame 11 and prevent the gas generated by the ink during drying from being trapped in the heating frame 11. The nano-photocatalyst coating is activated by the ultraviolet light emitted by the ultraviolet lamp tube 16, which generates free radicals with strong oxidizing properties. These free radicals can react with the molecules in the organic waste gas and decompose them into harmless carbon dioxide and water.

[0028] refer to Figure 3 and Figure 4 A filter port is provided on one side of the connecting frame 4, and the filter port is located below the ventilator 7. A medium-efficiency filter plate 19 is slidably connected inside the filter port.

[0029] As a technical optimization of this utility model, the medium-efficiency filter plate 19 can filter out dust and impurities in the air, preventing these dust and impurities from contaminating the cardboard and ink.

[0030] refer to Figure 2 and Figure 4 Inside the conveyor 1, a guide plate 20 is fixedly connected, and the guide plate 20 is used in conjunction with the vent 2. Inside the conveyor 1, a transition plate 21 is fixedly connected symmetrically with respect to the guide plate 20. A baffle plate 22 is fixedly connected to the top of the transition plate 21, and both baffle plates 22 are located inside the heating box 8.

[0031] As a technical optimization of this utility model, the hot air can be guided and blocked by the deflector plate 20, the transition plate 21 and the baffle plate 22, so that it can be evenly distributed inside the heating box 8, reducing heat loss.

[0032] refer to Figure 1 and Figure 5 A detachable windbreak strip is provided above the flow opening 10 on one side.

[0033] As a technical optimization of this utility model, the detachable wind deflector can be disassembled or installed as needed, which reduces the heat loss inside the heating box 8.

[0034] The working principle and usage process of this utility model are as follows: When using this ink rapid drying device to dry the cardboard printed by the cardboard printing machine, first, install the device at the discharge port of the cardboard printing machine to ensure that the printed cardboard can be transferred to the main drive roller and the driven roller on the conveyor 1. Then, connect the device to an external power supply. Next, start the heating tube 6 and the ventilator 7, so that the ventilator 7 draws air into the connecting frame 4. At this time, the air is filtered by the medium-efficiency filter plate 19, and then the air is heated by the heating frame 11. Then, the heated air is drawn into the distributor 3 through the ventilation channel 5 and discharged into the interior of the conveyor 1 through the ventilation port 2. At this time, the cooperation of the guide plate 20, the transition plate 21 and the baffle plate 22 can make the hot air evenly distributed inside the heating box 8, thereby forming a preheating effect. Then, turn on the quantum infrared heating lamp 12 and the curing lamp 13, and then start the conveyor 1 to drive the main drive roller and the driven roller to transport the cardboard. At this time, the cardboard enters through the flow port 10. The ink is placed inside the heating box 8, where its bottom is heated by hot air and its top is heated by the quantum infrared heating lamp 12. The quantum infrared heating lamp 12 uses its internal quantum-level light-emitting element to emit infrared rays within a specific frequency range. These infrared rays can resonate with the microstructure of ink molecules, penetrating deep into the ink molecules and directly exciting molecular vibrations, generating heat from within the ink to achieve rapid and efficient internal heating. Then, the photosensitive material in the ink is rapidly cured by the curing lamp 13, reducing drying time. This achieves simultaneous heating from top and bottom, accelerating the drying speed of the ink and improving the drying efficiency of the cardboard. The organic waste gas generated during the ink drying and heating process can be blown into the purification box 14 by the hot air, where it is adsorbed and filtered by the activated carbon plate 15. The ultraviolet lamp 16 is used to oxidize and decompose benzene, ammonia, and other organic compounds in the waste gas, and can also efficiently remove atmospheric pollutants such as CO, SO2, NO, and hydrocarbons, thereby achieving efficient filtration and purification of the waste gas.
