Description

Technical Field

[0001] This utility model relates to the field of textile fabric printing and dyeing technology, specifically to a high-efficiency short-process printing and dyeing device for textile fabrics. Background Technology

[0002] Dyeing and printing is a crucial step in textile processing. There are two main dyeing methods: one involves immersing the fabric in a dye bath, allowing for thorough contact between the fabric and dye. However, impurities on the fabric can contaminate the dye, requiring replacement of the dye in the bath after a period of time. This results in high dye consumption and significant waste, greatly increasing dyeing costs and making the process inconvenient. The other method involves spraying dye onto the fabric, but this results in poor dye penetration, leading to lower finished fabric quality and hindering product sales. Furthermore, most existing dyeing and printing equipment suffers from excessive dye consumption and uneven drying. Therefore, a more efficient, shorter-process dyeing and printing device is needed to address these issues while simultaneously meeting energy conservation, emission reduction, and environmental protection policy requirements.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN216378748U discloses a high-efficiency short-process dyeing and printing device for textile fabrics. The device includes a dyeing and printing device body, which comprises a base. The base is equipped with a feeding roller, a dye box, a dyeing box, a drying box, and a roll roller. The dyeing box contains a return box with a return port. A circulating feeding structure connects the dyeing box and the dye box. The dyeing box contains a dyeing roller. A hot air furnace is located on the top of the drying box, and an airflow separator is located inside the drying box.

[0004] While the aforementioned existing technical solutions can reduce dye consumption and improve drying effect, they only dry one side of the fabric during drying, which may cause uneven drying of the dye on the other side of the fabric. Furthermore, if there are wrinkles on the fabric surface during drying, it will also lead to uneven drying, thereby affecting the printing and dyeing effect of the fabric. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] A high-efficiency, short-process dyeing and printing device for textile fabrics includes a dyeing box 1. Multiple sets of guide rollers 2 are rotatably connected to the inner side of the dyeing box 1. A dyeing roller 3 is rotatably connected to the inner wall of the dyeing box 1 near its bottom. The amount of dye liquor inside the dyeing box 1 is higher than the top surface of the dyeing roller 3. A drying box 4 is installed on one side of the dyeing box 1. A water-squeezing assembly is installed on the side of the dyeing box 1 near the drying box 4. A discharge port is opened on one side of the drying box 4, and a feed port is opened on one side of the dyeing box 1. A double-sided drying mechanism is installed on the drying box 4, which includes a diversion assembly, a roller pushing assembly, and a movable... The device consists of a splitter component to disperse hot air onto the fabric surface, a roller component to smooth out wrinkles, and a movable component to assist the roller component in its pressing operation. In use, the splitter component disperses hot air onto the fabric surface, the roller component smooths out wrinkles, and the movable component assists the roller component in its pressing operation. It features a simple structure, convenient operation, and can dry both sides of the fabric. It also smooths out wrinkles during drying, further improving practicality and ensuring subsequent printing and dyeing effects.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the diversion assembly includes a dryer body 5 installed at the upper and lower ends of the drying chamber 4. The air outlet of the dryer body 5 is equipped with a corrugated pipe 7 extending to the inside of the drying chamber 4. The other end of the corrugated pipe 7 is equipped with an air outlet seat 6. First, the fabric is conveyed to the inside of the printing and dyeing box 1 through the feed inlet. The fabric passes along the surface of the first guide roller 2 and then passes under the dyeing roller 3 to continue to be conveyed to the inside of the drying chamber 4. Because the horizontal level of the dye liquor is higher than the top surface of the dyeing roller 3, the fabric can be immersed in the dye liquor for printing and dyeing processing.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the dewatering assembly includes an installation groove at the junction of the dyeing box 1 and the drying box 4. A lower scraper 15 is installed at the bottom of the inner wall of the installation groove. An adjustment groove is provided on the other side of the inner wall of the installation groove. A second threaded rod 17 is rotatably connected to the inner side of the adjustment groove. An adjustment seat 18 is threadedly connected to the outer side of the second threaded rod 17. An upper scraper 19 is installed at the bottom end of the adjustment seat 18. A second motor 20 is installed at the top end of the dyeing box 1. The drive end of the second motor 20 extends to the inner side of the adjustment groove and is fixedly connected to one end of the second threaded rod 17. Then, by starting the second motor 20, the second threaded rod 17 can be rotated, allowing the adjustment seat 18 to slide inside the adjustment groove, so that the upper scraper 19 approaches the lower scraper 15. After contacting the fabric, the excess dye liquid inside is scraped back into the dyeing box 1.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a diversion pipe 8 is embedded inside the air outlet 6. The cross-section of the diversion pipe 8 is mountain-shaped. The inner side of the diversion pipe 8 is connected to the inner side of the corrugated pipe 7. A blower head is installed at the other end of the diversion pipe 8. Furthermore, when the fabric is slowly conveyed to the inside of the drying box 4 for drying, the two sets of dryer bodies 5 can be activated to deliver hot air. The hot air is then conveyed along the corrugated pipe 7 to the inside of the diversion pipe 8, and finally blown out by the blower head to dry all sides of the fabric.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the movable component includes a movable column 12 installed on the other side of the top of the drying oven 4. A movable groove is formed on one side of the movable column 12, and a first threaded rod 13 is rotatably connected to the inner side of the movable groove. A movable plate 14 is threadedly connected to the outer side of the first threaded rod 13. A synchronous groove is formed at the top of the drying oven 4, which is slidably connected to the movable plate 14. One end of the movable plate 14 is fixedly connected to one side of one set of air outlet seats 6. A placement seat is installed on one side of the bottom of the inner wall of the drying oven 4, and one side of the placement seat is fixedly connected to one side of another set of air outlet seats 6. A first motor 16 is installed at the top of the movable column 12. The drive end of the first motor 16 extends into the movable groove and is fixedly connected to one end of the first threaded rod 13. Furthermore, simultaneously activating the first motor 16 drives the first threaded rod 13 to rotate, causing the movable plate 14 to move the upper air outlet seats 6 downwards. The first motor 16 can drive the first threaded rod 13 to rotate together by rotating forward and reverse, so as to drive the upper air outlet seat 6 to reciprocate. When the upper and lower sets of heating rollers 11 come into contact, there is a certain friction with the fabric. When moving, the torsion spring 10 can retract inside the deflection groove, thereby driving the deflection rod, the connecting plate 9 and the heating roller 11 to move. When moving, the fabric can be stretched. The heating roller 11 rotates between the two sets of connecting plates 9. When the fabric is fully stretched, the heating roller 11 will deflect and roll on the fabric. At the same time, the heating roller 11 can be started to heat, further ensuring the drying effect of the fabric. It can dry each section of the fabric. Holding the handle can be used with the hinge to drive the closing plate 21 to open and close, so as to inspect and maintain the double-sided drying mechanism. When the closing plate 21 is closed, the magnetic block 22 can be attracted and positioned with the iron block.

[0027] The implementation principle of the efficient short-process dyeing and printing device for textile fabrics in this application embodiment is as follows: The fabric is conveyed to the inside of the dyeing and printing box 1 through the feed inlet. The fabric passes along the surface of the first guide roller 2 and then passes under the dyeing roller 3 to continue to the inside of the drying box 4. Because the level of the dye liquor is higher than the top surface of the dyeing roller 3, the fabric can be immersed in the dye liquor for dyeing and printing. At the same time, the second motor 20 is started to drive the second threaded rod 17 to rotate, so that the adjusting seat 18 slides inside the adjusting groove, so that the upper scraper 19 approaches the lower scraper 15. After contacting the fabric, the excess dye liquor inside is scraped back into the dyeing and printing box 1. When the fabric is slowly conveyed to the inside of the drying box 4 for drying, the two sets of dryer bodies 5 can be started to deliver hot air. The hot air is delivered to the inside of the diversion pipe 8 through the corrugated pipe 7 and finally blown out through the blower head to dry both sides of the fabric. At the same time, the first motor 16 is started to drive the first threaded rod 13. Rotation causes the movable plate 14 to move the upper air outlet seat 6 downwards. The first motor 16 can rotate forward and reverse to drive the first threaded rod 13 to rotate together, achieving the effect of driving the upper air outlet seat 6 to reciprocate. When the upper and lower sets of heating rollers 11 come into contact, they have a certain friction with the fabric. When moving, the torsion spring 10 can retract inside the deflection groove, thereby driving the deflection rod, connecting plate 9, and heating roller 11 to move. When moving, the fabric can be stretched. The heating roller 11 rotates between the two sets of connecting plates 9. When the fabric is fully stretched, the heating roller 11 will deflect and roll on the fabric. At the same time, the heating roller 11 can be started to heat, further ensuring the drying effect of the fabric. It can dry each section of the fabric completely. Holding the handle can be used with the hinge to drive the closing plate 21 to open and close, so as to inspect and maintain the double-sided drying mechanism. When the closing plate 21 is closed, the magnetic block 22 can be attracted and positioned with the iron block.

[0028] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
