Description

Technical Field

[0001] This utility model relates to the field of fabric printing and dyeing technology, and in particular to a multi-color fabric printing and dyeing device. Background Technology

[0002] Multicolor fabric printing and dyeing equipment plays a vital role in the textile printing and dyeing industry, enabling the printing and dyeing of multiple colors and high-precision patterns on fabrics. These devices typically combine advanced mechanical design with a sophisticated control system to ensure the stability and accuracy of the printing and dyeing process.

[0003] The main components of a multi-color fabric dyeing and printing apparatus may include a feeding system, dye bath, sprayers, fabric guiding system, heat exchanger, circulating pump, and drying, steaming, or baking units. During the dyeing and printing process, the fabric is first fed into the dye bath through the feeding system. Then, driven by the circulating pump, the dye liquor flows over the surface or interior of the fabric, achieving dyeing. The sprayers accelerate the spraying of the dye liquor, improving dyeing efficiency and uniformity. The fabric guiding system ensures that the fabric moves along a specific path during the dyeing process to achieve the desired dyeing effect.

[0004] In the practical application of multi-color dyeing and printing equipment for fabrics, waste liquid collection is a crucial step. However, the currently commonly used collection cylinder method has significant drawbacks, especially since the waste liquid often contains impurities such as fabric threads, which poses numerous challenges to the subsequent treatment and reuse of the waste liquid.

[0005] Debris such as textile threads in wastewater reduces its quality. These impurities not only take up volume but also affect its purity, increasing the difficulty of subsequent treatment. Furthermore, they can clog pipes and filters in wastewater treatment equipment, leading to equipment malfunctions and increased downtime, ultimately impacting production efficiency and costs.

[0006] The presence of impurities such as fabric threads also limits the reuse of wastewater. During the dyeing and printing process, wastewater often contains high levels of residual dyes and auxiliaries, which can be recycled under appropriate conditions. However, the interference of impurities makes the purification and treatment of wastewater more complex and difficult, reducing the feasibility and economic efficiency of wastewater recycling.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 4 As shown, a multi-color dyeing apparatus for fabrics mainly consists of a base frame 1, a conveying and guiding device 2, a side frame 3, a transmission device 4, a dyeing roller assembly 5, and a dyeing tank 6. The base frame 1 serves as the foundation of the entire apparatus. The side frame 3 is installed at the upper center of the base frame 1, while the conveying and guiding device 2 is mounted on the base frame 1 to guide the fabric's conveying path. The dyeing roller assembly 5 is connected to the side frame 3 via the transmission device 4, ensuring stable operation of the dyeing roller assembly 5. The dyeing tank 6 is installed on the side frame 3 and adapted to the dyeing roller assembly 5 to achieve multi-color dyeing operations on the fabric.

[0027] A mounting base 7 is designed in the middle of the two side frames 3. The upper end of the base is connected to the receiving bin 9 via a buffer support 8. The main function of the receiving bin 9 is to collect the dye waste liquid generated during the printing and dyeing process to maintain a clean working environment.

[0028] To further optimize the wastewater discharge process, a connecting frame 10 is installed on the upper edge of the mounting base 7. A discharge trough 11 is provided on the side wall of the connecting frame 10, directly facing the dyeing tank 6 and the printing roller assembly 5 to facilitate smooth wastewater discharge. A bending groove 13 is designed at the lower end of the discharge trough 11, and a filter screen 12 is installed at the connection between the bending groove 13 and the discharge trough 11. The filter screen 12 filters out impurities in the wastewater, ensuring that the discharged wastewater meets certain cleanliness standards. A bin vibrator 14 is also provided at the lower end of the discharge trough 11. By vibrating the discharge trough 11 and the filter screen 12, the clean discharge of wastewater can be effectively promoted.

[0029] The mounting base 7 is designed with a mounting plate and crossbeams, with two crossbeams located at the lower end of the mounting plate and fixedly connected to the mounting plate by bolts. The crossbeams are also fixed to the side frame 3 by bolts, and anti-slip rubber strips are provided between the side frame 3 and the crossbeams to prevent slippage.

[0030] The buffer support 8 is bolted to the mounting base 7 to ensure the stability and safety of the receiving hopper 9. A limiting block connects the buffer support 8 and the receiving hopper 9, limiting the range of movement of the receiving hopper 9 to prevent excessive shaking and facilitating quick installation and disassembly. Anti-slip rubber pads are also provided at the connection between the buffer support 8 and the receiving hopper 9 to enhance friction and further ensure the stability of the receiving hopper 9.

[0031] The top view of the receiving hopper 9 is elliptical, which helps increase its capacity while maintaining structural stability. The cross-section of the receiving hopper 9 is funnel-shaped, which helps guide the waste liquid smoothly into the hopper. The bottom edge of the receiving hopper 9 is rounded, which reduces waste liquid residue inside the hopper and ensures complete collection. The opening of the receiving hopper 9 is directly opposite the connection between the filter screen 12, the discharge chute 11, and the bending chute 13, facilitating smooth discharge of waste liquid.

[0032] The connecting frame 10 is fixed to the mounting base 7 with bolts to ensure the stability and reliability of the connecting frame 10. The connecting frame 10 is connected to the discharge trough 11 with bolts to ensure the stable installation of the discharge trough 11. The filter screen 12 is fixed to the discharge trough 11 by welding to ensure that the filter screen 12 will not shift during use.

[0033] The discharge trough 11 and bending trough 13 are integrated into a single unit, which simplifies the structure, reduces costs, and improves the overall stability of the device. The bin vibrator 14 is bolted to the connecting frame 10, and it drives the discharge trough 11 to vibrate, thus promoting wastewater discharge. The angle between the bending trough 13 and the discharge trough 11 is adjustable, ranging from zero to sixty degrees. This design allows the device to adapt to different textile wastes, improving its applicability and flexibility.

[0034] Turn on the transmission device 4 to start the dyeing roller assembly 5. Start the conveying guide device 2 to guide the fabric along the predetermined path. Place the fabric into the conveying guide device 2 and begin conveying. As the fabric passes through the dyeing roller assembly 5, multi-color dyeing is performed. Dye waste liquid enters the dyeing tank 6 through the dyeing roller assembly 5 and then flows into the discharge tank 11.

[0035] Waste liquid flows into filter screen 12 through discharge trough 11, filtering out impurities. The filtered waste liquid continues to flow into bending trough 13 and is discharged by vibration of bin wall vibrator 14. The angle of bending trough 13 is adjusted (0 to 60 degrees) to accommodate the discharge requirements of different fabric wastes. The waste liquid finally flows into collection bin 9, whose elliptical design increases capacity and maintains structural stability. The funnel-shaped cross-section design of collection bin 9 facilitates smooth waste liquid flow, and the curved bottom reduces residue. Regularly inspect and clean filter screen 12 to ensure smooth waste liquid discharge. Clean collection bin 9 to prevent waste liquid residue and contamination. Inspect all connections to ensure there is no looseness or wear.

[0036] After completing the dyeing and printing operation, turn off the transmission device 4 and the conveyor guide device 2. Clean the equipment surface and work area to keep the environment clean.
