Description

Technical Field

[0001] The utility model relates to a drying device for printing and curing coatings, belonging to the technical field of printing and curing coatings. Background Art

[0002] A printing curing paint drying device is a device used to accelerate the chemical reaction, physical hardening or solvent volatilization of a curing agent or component. The device is commonly used in the printing industry to quickly dry and cure materials such as coatings, inks, and glues to improve production efficiency and ensure the quality and durability of the coating. Specifically, a printing curing paint drying device uses different drying methods such as hot air, ultraviolet radiation, infrared radiation, and electron beam radiation to quickly volatilize the solvent on the surface or inside of the coating or activate the curing agent, so that the coating can be quickly dried and cured.

[0003] During the hot air drying process, volatile organic compounds and other harmful gases may be released. If these pollutants are not effectively filtered, they will be deposited inside the equipment, in the surrounding environment, and on the surface of the cured coating, resulting in a decline in product quality. At the same time, the accumulation of pollutants will lead to a decline in indoor air quality and have an adverse effect on the health of operators. Inhalation of pollutants may cause respiratory problems, eye irritation, headaches, drowsiness and other discomfort symptoms. Long-term exposure to harmful gases may lead to chronic diseases such as respiratory diseases and nervous system problems.

[0004] For this purpose, a drying device for printing and curing coating is proposed. Utility Model Content

The filter assembly 8 includes a filter box 801, a fan 802, a semiconductor refrigeration rod 803, an exhaust pipe 804, a fixing sleeve 805, a welding rod 806, a diffusion pipe 807, an activated carbon filter 808 and a holder 809. The filter box 801 is fixedly connected to the middle end of the bottom of the U-shaped plate 1, the fan 802 is arranged on the back side of the filter box 801, the semiconductor refrigeration rod 803 is arranged at the bottom of the inner cavity of the filter box 801, the holder 809 is fixedly connected to the upper and lower sides of the inner cavity of the filter box 801, the activated carbon filter 808 is clamped in the holder 809, the exhaust pipe 804 is connected to the front side of the filter box 801, and the diffusion pipe 807 is connected to one end of the exhaust pipe 804.

[0026] Suction is generated by the fan 802, and the suction is transmitted to the inner side of the fixed frame 4 through the exhaust pipe 804 and the diffusion pipe 807, so that harmful gases generated in the drying process are sucked in. The harmful gases are sucked into the filter box 801 through the diffusion pipe 807 and the exhaust pipe 804, and filtered by the semiconductor refrigeration rod 803, so that the harmful substances generated in the drying process can be adsorbed. At the same time, the filtered gas is cooled by the semiconductor refrigeration rod 803 to avoid direct discharge of the filtered hot air, which will cause adverse effects on the external environment. Through the cooperation of the above-mentioned structure, the gas is effectively purified.

[0027] Example 2

[0028] In one embodiment, the fixing sleeve 805 is sleeved on the surface of the exhaust pipe 804, the welding rod 806 is welded to the left and right sides of the fixing sleeve 805, and one end of the welding rod 806 is welded to the front side of the fixing frame 4, an inspection cover 9 is arranged on the left side of the filter box 801, and the inner surface of the inspection cover 9 is threadedly connected to the left side of the filter box 801 by fastening screws, a transmission mechanism 2 is arranged on the inner side of the U-shaped plate 1, baffles 3 are welded on the front and rear sides of the U-shaped plate 1, a fan 6 is arranged on the top of the fixing frame 4, a heating tube 7 is arranged on the inner side of the fixing frame 4, and a heating wire 5 is wound around the surface of the heating tube 7.

By setting the inspection cover 9, it is convenient for the staff to take out the activated carbon filter 808 for replacement. By setting the baffle 3, the material on the top of the transmission mechanism 2 can be limited to prevent it from falling during the transportation process.

[0030] When the utility model is working: first, downward wind energy is generated by starting the fan 6, and the inner side of the fixed frame 4 is heated by the heating wire 5 and the heating tube 7 to convert it into hot air, and then the transmission mechanism 2 is started to transport the material. During the transportation process, when the material passes through the fixed frame 4, it is dried by the hot air. During the drying process, more harmful gases will be generated. At this time, suction is generated by the fan 802, and the suction is transmitted to the inner side of the fixed frame 4 through the exhaust pipe 804 and the diffusion pipe 807, so that the harmful gases generated in the drying process are sucked in. The harmful gases are sucked into the filter box 801 through the diffusion pipe 807 and the exhaust pipe 804, and filtered by the semiconductor refrigeration rod 803. The harmful substances generated in the drying process can be adsorbed. At the same time, the filtered gas is cooled by the semiconductor refrigeration rod 803 to avoid the hot air after filtering being directly discharged to avoid adverse effects on the external environment. Through the cooperation of the above-mentioned structure, the gas is effectively purified.
