Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and in particular relates to a non-woven fabric water-based ink printing and drying device. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, non-woven fabrics, and non-woven fabrics, are made of directional or randomly arranged fibers through friction, cohesion, bonding or a combination of these methods.

[0003] Traditional non-woven fabric printing mostly uses solvent-based inks for continuous printing on the base fabric. The printed and rolled fabric is then slit and processed according to subsequent use requirements. Although solvent-based inks have strong adhesion and bright colors, they have VOC (volatile organic compound) emission problems and are not in line with the current trend of green production. Therefore, water-based inks have gradually become an alternative due to their low toxicity and low pollution characteristics. Water-based inks use water as the main solvent, which reduces the release of harmful substances and is more in line with environmental protection requirements. However, compared with solvent-based inks, the water in water-based inks has a slower evaporation rate, and the natural scenery leads to a longer overall drying time. If hot air drying is used, since it has not formed a semi-solidified state, it is easy for the ink to spread, causing smearing and affecting the quality of the finished product. Utility Model Content

[0004] Based on the problems mentioned in the above background technology, the utility model provides a non-woven fabric water-based ink printing and drying device.

[0005] The technical solution adopted by the utility model is as follows: a non-woven fabric water-based ink printing and drying equipment, including a drying box, a drying component and a tensioning mechanism, the drying box having a feed port at the head end and a discharge port at the rear end; the drying component including two driving rollers rotatably connected to the drying box, one of the driving rollers being driven by a motor, a conveyor belt being provided between the two driving rollers, the conveyor belt being provided with a plurality of heat transfer holes, and an electric heating tube being provided between the upper and lower belt bodies of the conveyor belt in the drying box; the tensioning mechanism including a feeding structure arranged at the feed port in the drying box, and an auxiliary heating roller connected to the rear of the conveyor belt in the drying box near the discharge port, the lowest points of the feeding structure and the auxiliary heating roller being lower than the highest point of the conveyor belt.

[0006] Furthermore, the drying box is provided with a feeding structure at the feed port, and the feeding structure includes a first mounting plate and a second mounting plate relatively arranged on the two side walls of the drying box, and the first mounting plate and the second mounting plate are both provided with a first tensioning roller and a second tensioning roller, and the second tensioning roller is rotatably connected to the first mounting plate or the second mounting plate, and an adjustment mechanism is provided between the first tensioning roller and the second tensioning roller, for moving the first tensioning roller closer to the second tensioning roller.

[0007] Furthermore, the adjustment mechanism includes an adjusting screw, a sliding groove is provided on the first mounting plate, a fixed plate is provided at the end of the sliding groove, the adjusting screw is rotatably connected to the fixed plate, and a slider matching the sliding groove is threadedly connected to the adjusting screw; the two first tensioning rollers are rotatably connected to the connecting shaft, one end of the connecting shaft is slidably connected to the second mounting plate, and the other end of the connecting shaft is fixedly connected to the slider.

[0008] Furthermore, the drying box is provided with a water collecting cover on the top of the conveyor belt, and a drying net is provided on the top of the water collecting cover.

[0009] Furthermore, the electric heating tube is bent in an S-shape and mounted on the drying box.

[0011] Beneficial effects of the utility model:

[0012] 1. Through the setting of the drying component, the driving roller is driven by the motor (not shown in the figure) set on the drying box, driving the conveyor belt to realize the transmission of non-woven fabrics. The heat of the electric heating tube is dissipated through the heat transfer hole to achieve the drying of the water-based ink. The uniform transportation process ensures the consistency and stability of the drying; secondly, through the setting of the tensioning mechanism, the feeding structure, the conveyor belt and the auxiliary heating roller, it is ensured that the entire non-woven fabric maintains appropriate tension throughout the drying process, improving the drying effect while preventing the non-woven fabric from wrinkling. The external winding mechanism can directly realize winding, with a high degree of automation.

[0013] 2. The hot air blown out from the auxiliary heating roller dries the semi-solidified ink again. The water-based ink will not be easily contaminated during the process of transitioning from a semi-solidified state to a dry state. Therefore, the auxiliary heating roller can simultaneously achieve the functions of tensioning and secondary drying. The overall environment is dry, effectively achieving thorough drying of the non-woven fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] By adopting the above technical solution, through the setting of the drying component, the driving roller 2 is driven by the motor (not shown in the figure) set on the drying box 1, driving the conveyor belt 21 to realize the transmission of the non-woven fabric 5, wherein the heat of the electric heating tube 23 is dissipated through the heat transfer hole 22 to realize the drying of the aqueous ink, and the uniform conveying process ensures the consistency and stability of the drying; secondly, through the setting of the tensioning mechanism, through the setting of the feeding structure, the conveyor belt 21 and the auxiliary heating roller 3, it is ensured that the entire non-woven fabric 5 maintains appropriate tension during the entire drying process, while improving the drying effect, preventing the non-woven fabric 5 from wrinkling, and the external winding mechanism can directly realize winding, with a high degree of automation.

[0023] In order to ensure a better tensioning effect, feeding structures can also be provided at both the feed port and the discharge port.

[0024] As a preferred embodiment, the feeding structure includes a first mounting plate 13 and a second mounting plate 14 disposed oppositely on the two side walls of the drying oven 1. A first tensioning roller 15 and a second tensioning roller 16 are disposed on each of the first mounting plate 13 and the second mounting plate 14. The second tensioning roller 16 is rotatably connected to the first mounting plate 13 or the second mounting plate 14. An adjustment mechanism is disposed between the first tensioning roller 15 and the second tensioning roller 16 for moving the first tensioning roller 15 closer to the second tensioning roller 16. The first mounting plate 13 and the second mounting plate 14 are located on either side of the feed port 11 of the drying oven 1. When the non-woven fabric 5 is fed, two sets of first tensioning rollers 15 and second tensioning rollers 16 are positioned on either side of the non-woven fabric 5. The first tensioning roller 15 is pressed downward toward the second tensioning roller 16 by the adjustment mechanism to position the two sides of the non-woven fabric 5. The non-woven fabric 5 then undergoes an overall tensioning process through the conveyor belt 21, the auxiliary heating roller 3, and finally, connection to an external winding mechanism.

[0025] As a preferred embodiment, the adjustment mechanism includes an adjusting screw 4. A slot 131 is formed on the first mounting plate 13, and a fixed plate 132 is provided at the end of the slot 131. The adjusting screw 4 is rotatably connected to the fixed plate 132. A slider 41 matching the slot 131 is threadedly connected to the adjusting screw 4. The two first tensioning rollers 15 are both rotatably connected to a connecting shaft 151. One end of the connecting shaft 151 is slidably connected to the second mounting plate 14, and the other end of the connecting shaft 151 is fixedly connected to the slider 41. The setting of the adjusting screw 4 enables the movement of the first tensioning roller 15 toward the second tensioning roller 16. The rotation of the adjusting screw 4 drives the slider 41, which is limited by the slot 131 on the first mounting plate 13, to move up and down. The two first tensioning rollers 15 are synchronized via the connecting shaft 151. One end of the connecting shaft 151 is fixed to the slider 41, and the other end is slidably connected to the second mounting plate 14, so that the adjusting screw 4 drives the first tensioning roller 15 to move toward the second tensioning roller 16.

[0026] As a preferred embodiment, the drying box 1 is provided with a water collection cover 17 located on top of the conveyor belt 21, and a drying net 171 is installed on top of the water collection cover 17. Due to the conical water collection cover 17, water vapor from the primary drying process evaporates upward and is collected by the water collection cover 17. The drying net 171 can be filled with granular dry matter to absorb the water vapor, thereby providing good ventilation and preventing overheating in the drying box 1.

[0027] As a preferred embodiment, the electric heating tube 23 is bent in an S-shape and mounted on the drying oven 1. The bent electric heating tube 23 is mounted on the drying oven 1 via a bracket or mounting member. The bent arrangement increases the contact surface, improves heat transfer efficiency, and effectively achieves preliminary drying of the nonwoven fabric 5.

[0028] As a preferred embodiment, a rotating shaft 31 is rotatably connected within the drying oven 1. The auxiliary heating roller 3 is mounted on the rotating shaft 31. The auxiliary heating roller 3 is a hollow structure having a plurality of through-holes 32 communicating with the rotating shaft 31. The rotating shaft 31 is connected to a hot air blower. The hot air blown from the auxiliary heating roller 3 further dries the semi-solidified ink. The water-based ink is less susceptible to contamination during the transition from the semi-solidified state to the dry state. Therefore, the auxiliary heating roller 3 can simultaneously achieve tensioning and secondary drying, resulting in a dry environment and effectively achieving thorough drying of the nonwoven fabric 5.
