Description

Technical Field

[0001] The present application relates to the field of weaving technology, and in particular to a low-water dyeing device for polyester taffeta fabrics. Background Art

[0002] Polyester taffeta fabric is a traditional chemical fiber fabric with the advantages of durability, low price, good quality, easy care, bright colors, etc. It can be used to make outdoor tents, awnings, clothing, supplies, etc. Therefore, it is necessary to develop a high-strength anti-break polyester taffeta low-water weaving process.

[0003] The Chinese patent announcement number is CN213295778U, and the announcement date is May 28, 2021. The name of the invention is a polyester taffeta fabric dyeing device. The application discloses a dyeing device, including a dyeing box, in which a plurality of fixed cloth rollers are installed, and the upper and lower ends of the fixed cloth rollers are respectively provided with stirring plates and spindles. The stirring plate at the upper end can be raised and lowered for stirring, and the spindle at the lower end can be rotated for stirring. Different forms of stirring at the upper and lower ends can increase the intensity of stirring.

[0004] However, in the above-mentioned related technologies, the dyeing liquid is used to dye the polyester taffeta fabric in the form of liquid dye, and water is needed for rinsing after dyeing, which seriously wastes water resources.

[0005] For this purpose, referring to the Chinese patent announcement number CN103981658B, the announcement date is April 6, 2016, the invention is called a foam dyeing method and device for towel fabrics, which includes the towel fabrics to be dyed are guided by multiple cloth guide rollers to pass through four dyeing tanks in sequence, each dyeing tank is provided with an upper dyeing roller and a foaming device, when the towel fabrics to be dyed pass through the dyeing tank, the upper dyeing roller transfers the fine dye foam generated by the foaming device to the towel fabrics to be dyed to achieve foam dyeing. The foam dyeing process uses less water and is environmentally friendly than traditional dyeing.

[0006] However, in the above foam dyeing device, the fabric to be dyed is located above the upper dyeing roller, and the dyeing tank is located below the upper dyeing roller. During the dyeing process, the rotating upper dyeing roller first dips the foam in the dyeing tank below, and then rotates to the upper side to transfer the dipped foam to the lower surface of the fabric to be dyed, thereby achieving the transfer and dyeing of the foam. However, the fabric to be dyed is continuously moving forward, and the foam adhering to the lower surface of the fabric to be dyed may be brought out of the dyeing tank and splashed, thereby increasing the loss of foam dye and affecting the weaving environment. Utility Model Content

[0007] In order to improve the problem of splashing of foam after being carried by fabric during foam dyeing, the present application provides a low-water dyeing device for polyester taffeta fabric.

[0008] The present application provides a low-water dyeing device for polyester taffeta fabric, which adopts the following technical solution:

[0009] A low-water dyeing device for polyester taffeta fabrics comprises a frame, on which a transport roller group for transporting fabrics to be dyed, a dyeing component for transferring dyeing foam to the fabrics to be dyed, and a dye liquid tank located below the dyeing component are arranged, and a scraping component is also arranged on the frame, the scraping component comprises a mounting frame arranged on the frame and a scraping plate arranged on the mounting frame, the scraping plate can abut against the fabrics to be dyed, the scraping component is located behind the dyeing component along the running direction of the fabrics to be dyed, and the scraping component is located above the dye liquid tank.

[0010] By adopting the above technical solution, the dyeing is achieved when the fabric to be dyed and the dyeing foam contact each other in the dyeing component, and the excess foam is scraped off by the scraping component after the dyeing is completed; the foam overflowing during the dyeing process and the foam falling during the scraping are both collected in the dye liquid tank for subsequent recycling, thereby improving the problem of splashing caused by the foam being carried by the fabric during the foam dyeing process.

[0011] Optionally, a sliding groove is provided on the frame, and the extension direction of the sliding groove is not parallel to the direction of the fabric to be dyed; the scraping assembly also includes connecting parts fixed at both ends of the mounting frame, and the connecting parts can be passed through and slidably connected in the sliding groove along the extension direction of the sliding groove; a first connecting part is provided on the connecting part to fix the connecting part to the frame.

[0012] By adopting the above technical solution, the connecting member can be moved in the sliding groove and then fixed by the first connecting part, so as to adjust the distance between the mounting frame and the fabric to be dyed, and the scraper plate is installed on the mounting frame, so that the distance between the scraper plate and the fabric to be dyed can also be adjusted, so that the operator can adjust the contact force of the scraper plate on the fabric.

[0015] Optionally, an arc-shaped groove is provided on the mounting frame for the connecting rod to pass through, and the bottom end of the arc-shaped groove is higher than the bottom end of the mounting frame.

[0016] By adopting the above technical solution, the opening range of the arc groove is restricted, thereby limiting the rotation angle of the scraper plate. Therefore, when the second connecting part fails accidentally, the scraper plate can be restricted by the arc groove even if it rotates downward under the action of gravity, rather than falling directly to the lowest point, thereby reducing the probability of the scraper plate hitting the fabric and causing damage to the fabric.
