Description

Technical Field

[0001] This utility model relates to the field of dyeing and finishing technology, specifically to a device for dyeing and finishing blended fabrics in dark colors. Background Technology

[0002] Dyeing and finishing is an industrial process that uses chemical and physical techniques to process and optimize the function of textiles; it is a term from the field of engineering.

By removing impurities, imparting colors and patterns, and improving performance, it enhances the artistry and practicality of the fabric.

[0003] Chinese patent document CN212426433U discloses a dark-color dyeing and finishing device for blended fabrics. The device is equipped with a horizontal pipe, a circulation pump, and an outlet pipe. The circulation pump extracts the dye from inside the dyeing box and transports it to the inside of the horizontal pipe. The dye inside the horizontal pipe is discharged through the outlet pipe. This process is repeated to mix the dye inside the dyeing box, thereby reducing dye precipitation and ensuring the uniformity of dyeing.

[0004] In the above scheme, the dye in the upper part of the dyeing box is transported to the bottom through a circulating pump and pipeline system, so that the flow of liquid maintains the uniformity of dyeing. However, this method is prone to causing the dye to accumulate in the corners and low flow rate areas of the dyeing box, resulting in uneven dyeing and reducing the dyeing quality of the fabric. At the same time, the long-term operation of the circulating pump is prone to energy waste and equipment wear. Utility Model Content

[0031] Example 1

[0032] like Figure 1-3 As shown, the present invention proposes a dark-color dyeing and finishing device for blended fabrics, including a dyeing box 1, a conveying roller 7, and a transmission assembly.

[0033] The limiting roller 2 is rotatably installed on the inner bottom of the dyeing box 1. The side of the limiting roller 2 is provided with a stirring roller 3 for stirring the dye inside the dyeing box 1 in the use state. The stirring roller 3 consists of a rotating shaft and plates arranged at equal angles around the rotating shaft, and is used to stir the dye inside the dyeing box 1 through the plates in the use state.

[0034] The transmission assembly is located on the outside of the dyeing box 1 and connected to the limiting roller 2 and the stirring roller 3. The transmission assembly is a speed-increasing structure, which is used to rotate along with the movement of the blended fabric when the limiting roller 2 is conveying the blended fabric. The limiting roller 2 drives the stirring roller 3 to rotate in the dye through the transmission assembly, and the rotation speed of the stirring roller 3 is greater than that of the limiting roller 2. This makes the stirring roller 3 generate a stronger stirring effect on the dye during the rotation process, thereby improving the uniformity and flowability of the dye, reducing the accumulation of dye in the corners of the box and the low flow rate area, and improving the dyeing quality of the fabric.

[0035] The conveyor rollers 7 are all rotatably installed at one end of the top of the dyeing box 1. Above the conveyor rollers 7 is a pressing component that is connected to the dyeing box 1 and discharges excess dye from the blended fabric in use.

[0036] In this embodiment, the blended fabric is conveyed and placed inside the dyeing box 1 for dyeing. An external traction device pulls the blended fabric, causing it to move towards the conveying roller 7 below the limiting roller 2, thus achieving continuous dyeing. Simultaneously, the limiting roller 2 rotates as the blended fabric moves, and drives the stirring roller 3 to rotate through the transmission component. The stirring roller 3 agitates the dye in the dyeing box 1, improving its uniformity. At the same time, the transmission component is a speed-increasing structure, so that the stirring roller 3 rotates at a higher speed than the limiting roller 2, thereby generating a stronger agitation effect on the dye during rotation, further improving the uniformity and flowability of the dye, reducing its accumulation in the corners of the box and in low-flow-rate areas, and improving the dyeing quality of the fabric. In addition, the conveying roller 7, in conjunction with the pressing component, presses the dye on the fabric, discharging excess dye, reducing waste, and improving the efficiency of subsequent drying.

[0037] Example 2

[0038] like Figure 1-2 As shown, the present invention proposes a dark-color dyeing and finishing device for blended fabrics. Compared with the first embodiment, the difference in this embodiment is that the transmission component includes a first sprocket 4, a chain 5, and a second sprocket 6.

[0039] The first sprocket 4 is installed at the end of the limiting roller 2;

[0040] The second sprocket 6 is installed at the end of the stirring roller 3, wherein the size and number of teeth of the second sprocket 6 are smaller than the size and number of teeth of the first sprocket 4;

[0041] Chain 5 is mounted on the first sprocket 4 and the second sprocket 6.

[0042] In an optional embodiment, the outer circular surface of the limiting roller 2 is provided with a plurality of grooves 12 arranged at equal angles around the center of the limiting roller 2. These grooves are used to transport the blended fabric during use and to rotate along with the movement of the blended fabric. This allows the limiting roller 2 to also agitate the dye inside the dyeing box 1, further enhancing the agitation effect on the dye. At the same time, the grooves 12 increase the friction between the blended fabric and the limiting roller 2 during transport, preventing the fabric from slipping during transport, thereby ensuring the stability of the fabric operation and improving the dyeing and finishing effect.

[0043] In this embodiment, the limiting roller 2 rotates synchronously with the conveying speed of the blended fabric and transmits power to the first sprocket 4. The first sprocket 4 drives the second sprocket 6 to rotate via the chain 5, thereby driving the stirring roller 3 to rotate. The stirring roller 3 agitates the dye, ensuring that the dye remains uniform throughout the dyeing and finishing process. This effectively avoids color difference defects in the fabric due to uneven dye distribution. At the same time, because the size and number of teeth of the second sprocket 6 are smaller than those of the first sprocket 4, a speed-increasing structure is formed between the first sprocket 4, the chain 5, and the second sprocket 6. This ensures that the stirring roller 3 maintains high stirring efficiency even when the limiting roller 2 is running at low speed, significantly improving the adaptability of the equipment under different working conditions and achieving energy-saving and high-efficiency technical effects.

[0044] Example 3

[0045] like Figure 3 As shown, the present invention proposes a dark-color dyeing and finishing device for blended fabrics. Compared with the first embodiment, the difference in this embodiment is that the pressing component includes a pressure roller 8, a connecting plate 9, a spring 10, and a mounting frame 14.

[0046] Mounting bracket 14 is positioned at the top of dyeing box 1 and above conveyor roller 7;

[0047] Connecting plate 9 is installed inside mounting bracket 14;

[0048] The pressure roller 8 is rotatably mounted on the inner side of the connecting plate 9;

[0049] There are multiple springs 10, and all of the multiple springs 10 are mounted on the top of the connecting plate 9 and connected to the mounting bracket 14.

[0050] In an optional embodiment, a U-shaped through hole is provided at the end of the mounting bracket 14, and the end of the connecting plate 9 is located inside the U-shaped through hole of the mounting bracket 14, which is used to limit the position of the connecting plate 9 during use, so that the connecting plate 9 can slide up and down inside the U-shaped through hole of the mounting bracket 14.

[0051] In an optional embodiment, the inner wall of the U-shaped through hole of the mounting bracket 14 is provided with a groove 15, and the end of the connecting plate 9 is provided with a slide bar 16. When the connecting plate 9 and the mounting bracket 14 are installed together, the slide bar 16 is accommodated in the groove 15 to further limit the position of the connecting plate 9 during use and improve the stability of the connecting plate 9.

[0052] In this embodiment, the connecting plate 9 is moved towards the conveying roller 7 inside the mounting frame 14 by the elastic force of the spring 10, so that the connecting plate 9 drives the pressure roller 8 to press tightly against the fabric surface conveyed by the conveying roller 7, so that the fabric is subjected to pressure during the conveying process, which in turn drives the conveying roller 7 and the pressure roller 8 to rotate. At the same time, the conveying roller 7 and the pressure roller 8 cooperate to squeeze out excess dye from the fabric, avoiding dye waste and improving the efficiency of the subsequent drying process.

[0053] Example 4

[0054] like Figure 3 As shown, the present invention proposes a dark-color dyeing and finishing device for blended fabrics. Compared with Embodiment 3, this embodiment also includes a rotating handle 11 and a lead screw 13.

[0055] The lead screw 13 is fixedly installed on the top of the connecting plate 9, and its top extends through the mounting bracket 14 to the top of the mounting bracket 14;

[0056] The handle 11 is threaded onto the top of the lead screw 13 and is movably connected to the top of the mounting bracket 14.

[0057] In this embodiment, by rotating the handle 11 at the top of the mounting frame 14, the handle 11 moves up and down in the middle of the screw 13, and then the position of the pressure roller 8 is adjusted by the connecting plate 9, thereby adapting to fabrics of different thicknesses and the fabric threading, improving the versatility and practicality of the equipment.

[0058] In this invention, by rotating the handle 11 at the top of the mounting frame 14, the handle 11 moves upward at the middle of the lead screw 13, and then the pressure roller 8 moves upward through the connecting plate 9. This causes the fabric to move from below the limiting roller 2 between the conveying roller 7 and the pressure roller 8, and extend into subsequent processes and the traction device. Reversing the handle 11 causes the spring force of the spring 10 to move the connecting plate 9 inside the mounting frame 14 towards the conveying roller 7, causing the connecting plate 9 to drive the pressure roller 8 to press tightly against the fabric surface conveyed by the conveying roller 7. Simultaneously, the traction device moves the fabric, and the limiting roller 2 moves the fabric in the dye inside the dyeing box 1, allowing the fabric to be fully immersed in the dye. The fabric movement also causes the limiting roller 2 to rotate inside the dyeing box 1, transmitting power to the first sprocket 4. 4. The chain 5 drives the second sprocket 6 to rotate, which in turn drives the stirring roller 3 to rotate. The stirring roller 3 agitates the dye, ensuring that the dye remains uniform throughout the dyeing and finishing process. This effectively avoids color difference defects in the fabric caused by uneven dye distribution. At the same time, because the size and number of teeth of the second sprocket 6 are smaller than those of the first sprocket 4, a speed-increasing structure is formed between the first sprocket 4, the chain 5, and the second sprocket 6. This makes the rotation speed of the stirring roller 3 higher than that of the limiting roller 2, thereby generating a stronger agitation effect on the dye during rotation. This further improves the uniformity and flowability of the dye, reduces its accumulation in the corners of the box and in low-flow-rate areas, improves the dyeing quality of the fabric, and subjects the fabric to the squeezing force between the conveying roller 7 and the pressure roller 8 during the conveying process. This effectively removes excess dye, reduces dye waste, and improves the efficiency of subsequent drying.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
