Description

Technical Field

[0001] The utility model relates to the field of textile printing and dyeing equipment, in particular to a double-sided uniform spray-dyeing device for cloth. Background Art

[0002] In the textile industry, fabric spraying is a crucial process that directly affects the appearance and quality of the finished product. Traditional spraying devices often find it difficult to ensure uniform distribution of dyes on both sides of the fabric, resulting in quality problems such as color difference and color spots in the finished product. In addition, the existing spraying technology is even more difficult to ensure uniformity when dealing with thick or multi-layer fabrics. Therefore, it is particularly important to develop a device that can achieve high-uniformity double-sided spraying. For example, the patent number CN208965231U discloses that the device has the following deficiencies in fabric spraying: 1. The device cannot ensure uniform distribution of liquid on the surface of the fabric, resulting in uneven dyeing or spots. 2. The device cannot recycle excess dye after spraying, resulting in dye accumulation inside the device. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies of the prior art, the utility model aims to provide a double-sided uniform spray-dyeing device for fabrics, which solves the problems existing in the prior art. The inclined design of the scraper plate and the arrangement of small holes and cavities are used to effectively control the flow and distribution of the liquid, thereby ensuring uniform coverage of the liquid on the surface of the fabric. By setting up a recovery box and corresponding interfaces, the liquid in the spraying process can be recovered, which reduces the waste of liquid in the spraying process and also reduces the pollution to the environment. The designed spray-dyeing structure and recovery device can realize uniform spray-dyeing on both sides of the fabric, and recycle the excess dye after spray-dyeing, while avoiding the accumulation of dye inside the device and maintaining the continuity of production.

[0030] The control box 6 starts the equipment, and the first nozzle 11 and the second nozzle 20 start working, spraying dye on both sides of the cloth in sequence. Since the first nozzle 11 and the second nozzle 20 are arranged in parallel, it can ensure that the spraying range is wide and uniform.

[0031] The fabric after spraying passes through the first pressing plate 12 and the second pressing plate 16, and the first pressing plate 12 and the second pressing plate 16 can move up and down, and with the cooperation of the first scraper plate 13 and the second scraper plate 17, it can adapt to fabrics of different thicknesses and ensure the quality of spraying. At the same time, the first pressing plate 12 and the second pressing plate 16 can allow excess dye to enter from the small hole 22 above the scraper plate, flow along the internal liquid inlet cavity 21 to the seepage plate 18, and then enter the recovery box 4 to ensure full recovery.

[0032] Then, the fabric is heated and dried by the first drying head 14 and the second drying head 15, so that the dye can be better penetrated and fixed into the fabric. The fabric after the spraying is collected by the winding roller 3.

[0033] The upper partition 7 is provided with a cavity 19 with an inclination angle of 80°, which can recover the excess dye that seeps from the fabric after spraying. The excess dye can flow from the hose 9 into the recovery box 4 through the first interface 71 and the second interface 81, so as to realize the recycling of dye and reduce waste.

[0034] Working principle: During operation, the unwinding roller 2 allows the cloth to enter the box 1, and the cloth enters the spraying area through multiple guide rollers 5. Through the area above the upper partition 7, the cloth is sprayed on the first side by the first nozzle 11, and then squeezed evenly by the first pressing plate 12. At the same time, excess dye enters from the small holes 22 above the scraper plate and the seepage plate 18, flows along the internal liquid inlet cavity 21 to the seepage plate 18, and then enters the recovery box 4. At the same time, the first drying head 14 dries, and then is guided by the guide roller 5 so that the other side of the cloth faces the second nozzle 20, and then is squeezed and spread evenly by the second pressing plate 16, and dried by the second drying head 15. Finally, it goes from the cloth outlet 102 to the outside of the box 1 and is collected by the winding roller 3.
