Description

Technical Field

[0001] This invention relates to the field of fabric dyeing technology, and more specifically, to a fabric trough assembly for a dyeing machine. Background Technology

[0002] Overflow dyeing machines are core equipment in wet textile processing. During the continuous high-speed flow of the dye liquor, thin synthetic fibers, elastic knitted fabrics, and microfiber fabrics are highly susceptible to defects such as overlapping, twisting, and creases under high-temperature dyeing conditions. In existing conventional dyeing machine fabric tank structures, the fabric is not buffered after high-speed output through the guide tube. This makes the fabric prone to twisting and folding during movement. Dye liquor cannot fully penetrate the overlapping areas, directly forming permanent creases during the high-temperature setting stage, significantly reducing the finished product yield. Furthermore, the guide channel lacks a gradually expanding cross-sectional area, causing the fabric and dye liquor to move synchronously at high speed. The fabric clings tightly to the tank wall, unable to fully expand, resulting in prominent inward curling edges on wide fabrics. Summary of the Invention

[0003] In order to overcome the defects of the existing technology, the present invention provides a fabric trough assembly for a dyeing machine, which aims to solve the defects of the existing dyeing machine fabric trough that is prone to twisting and folding of the fabric, resulting in permanent creases, color difference and color pattern on the fabric surface during high-temperature dyeing.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a fabric trough assembly for a dyeing machine, comprising a fabric unfolding section and a fabric smoothing section; The fabric unfolding section includes a liquid inlet cylinder. One end of the liquid inlet cylinder is provided with an arc-shaped fabric guide tube. The lower end of the arc-shaped fabric guide tube is provided with a fabric inlet. The other end is provided with a fabric blocking buffer tube, so that the fabric is guided through the arc-shaped fabric guide tube towards the fabric blocking buffer tube and the fabric collides with the fabric blocking buffer tube. The end of the fabric blocking buffer tube away from the fabric inlet is connected to a horn tube. The end of the horn tube away from the fabric blocking buffer tube is connected to an inclined first shaping groove. The fabric smoothing section includes a fabric storage cylinder, which is connected to the liquid inlet cylinder. A second shaping trough is inclinedly arranged inside the fabric storage cylinder, and the second shaping trough is connected to the first shaping trough. An angle α is formed between the first shaping trough and the second shaping trough, so that the dye liquor and fabric are transported along the inclined surface under their own weight. A liquid storage trough is provided at the end of the second shaping trough away from the first shaping trough, so that the fabric is immersed in the dye liquor in the liquid storage trough. A raised section is provided at the end of the fabric storage cylinder away from the liquid inlet cylinder, and the raised section is provided with a fabric output port.

[0005] In the above-mentioned fabric trough assembly of a dyeing machine, the upper end of the fabric buffer tube is provided with a V-shaped upper wall, and the side view projection of the upper wall and the output port of the arc-shaped fabric guide tube partially overlaps.

[0006] In the above-mentioned fabric trough assembly of a dyeing machine, the lower end of the fabric buffer tube is provided with a first inclined surface, and the first inclined surface and the end of the upper wall away from the arc-shaped fabric guide tube form a flared mouth.

[0007] In the above-mentioned fabric trough assembly of a dyeing machine, the fabric inlet, the fabric buffer tube, and the trumpet tube form an independent fabric unfolding cavity. The liquid inlet cylinder is provided with a dyeing liquid cavity, and the liquid inlet cylinder is provided with a liquid inlet that communicates with the dyeing liquid cavity. The upper end of the trumpet tube is provided with a first through hole, so that the fabric unfolding cavity communicates with the dyeing liquid cavity.

[0008] In the above-mentioned fabric trough assembly of a dyeing machine, the diameter of the trumpet tube gradually increases from the fabric buffer tube toward the first shaping trough.

[0009] In the fabric trough assembly of the dyeing machine described above, the lower inner end of the first shaping trough is provided with a second inclined surface, and the second inclined surface is provided with a plurality of first ribs arranged along the fabric conveying direction. The second inclined surface slopes downward from the trumpet tube toward the second shaping trough.

[0010] In the fabric trough assembly of the dyeing machine described above, the lower inner end of the second shaping trough is provided with a third inclined surface. The third inclined surface is provided with a plurality of second ribs arranged along the fabric conveying direction. The third inclined surface slopes downward from the second inclined surface toward the liquid storage tank. An included angle α is formed between the lower end surfaces of the second and third inclined surfaces. The included angle α is 170°-178°.

[0011] In the above-mentioned fabric tank assembly of a dyeing machine, a dye liquor recovery chamber is provided in the fabric storage cylinder, and a plurality of second through holes are provided at the lower end of the liquid storage tank so that the dye liquor recovery chamber is connected to the liquid storage tank, and a dye liquor recovery port is provided at the lower end of the dye liquor recovery chamber.

[0012] The beneficial effects of this invention are as follows: After the fabric is output through the arc-shaped guide pipe, it first impacts the baffle buffer pipe. The kinetic energy of the high-speed fabric is absorbed by the pipe wall, and the fabric speed is greatly slowed down. This causes the stacked fabric to automatically separate into layers, completing the first fabric unfolding. This reduces fabric stacking and twisting from the source. The rear end of the baffle buffer pipe is connected to a gradually expanding trumpet pipe, and the channel space continues to increase. This causes the fabric and dye liquor flow rates to decrease synchronously, allowing the fabric to quickly spread out in the initial unfolding state. Due to the relatively long conveying length, the fabric droops under its own weight and adheres to the first and second shaping grooves, continuing to move forward and upward. This further flattens the fabric into a spread-out and loose state, preventing local stacking and compression. During high-temperature soaking, no permanent creases are formed. After the dye liquor flows into the storage tank, it still maintains a certain liquid level, allowing the fabric to float semi-float in the storage tank and continue to move, thus making the fabric dyed more evenly.

Detailed Implementation

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1 Combination Figures 1 to 7The fabric trough assembly of a dyeing machine shown includes a fabric unfolding section 1 and a fabric smoothing section 2. The fabric unfolding section 1 includes an inlet cylinder 10, with an arc-shaped fabric guide tube 13 at one end inside the inlet cylinder 10. The lower end of the arc-shaped fabric guide tube 13 has a fabric inlet 12, and the other end has a fabric blocking buffer tube, so that the fabric 3 is guided through the arc-shaped fabric guide tube 13 towards the fabric blocking buffer tube and collides with the fabric blocking buffer tube. The end of the fabric blocking buffer tube away from the fabric inlet 12 is connected to a trumpet tube 16, and the end of the trumpet tube 16 away from the fabric blocking buffer tube is connected to an inclined first shaping groove 17. The material leveling section 2 includes a fabric storage cylinder 20, which is connected to the liquid inlet cylinder 10. A second shaping groove 22 is inclinedly arranged inside the fabric storage cylinder 20. The second shaping groove 22 is connected to the first shaping groove 17. An included angle α is formed between the first shaping groove 17 and the second shaping groove 22, so that the dye liquor and fabric 3 are conveyed along the inclined surface under their own weight. A liquid storage tank 24 is provided at the end of the second shaping groove 22 away from the first shaping groove 17, so that the fabric 3 is immersed in the dye liquor in the liquid storage tank 24. A raised section 25 is provided at the end of the fabric storage cylinder 20 away from the liquid inlet cylinder 10, and a fabric output port 26 is provided on the raised section 25.

[0023] In this embodiment, a connecting flange is provided at the fabric output port 26 for installing a fabric lifting wheel. The fabric lifting wheel drives the fabric 3 to move and be conveyed. The fabric 3 is sewn end to end. The fabric 3 enters the fabric unfolding section 1 and the fabric leveling section 2, and then is output to the external dyeing machine body before re-entering the fabric unfolding section 1 and the fabric leveling section 2 for cyclic dyeing. After being output through the arc-shaped fabric guide tube 13, the fabric 3 first impacts the fabric blocking buffer tube. The kinetic energy of the high-speed fabric is absorbed by the tube wall, and the fabric speed is greatly slowed down, causing the stacked fabric 3 to automatically separate into layers, completing the first fabric unfolding. This reduces fabric stacking and twisting from the source. After the fabric blocking buffer tube... The end is connected to the gradually expanding trumpet tube 16, and the channel space continues to increase, causing the fabric 3 and the dye liquor flow rate to decrease synchronously. This allows the fabric 3 to quickly spread out in its initial unfolded state. Due to the relatively long conveying length, the fabric 3 droops under its own weight and adheres to the first shaping groove 17 and the second shaping groove 22 as it continues to move forward and upward. This further flattens the fabric 3 into a spread-out and loose state, preventing local stacking and compression. During the high-temperature soaking process, no permanent creases are formed. After the dye liquor flows into the storage tank 24, it still maintains a certain liquid level, causing the fabric 3 to float semi-float in the storage tank 24 and continue to move, thereby making the dyeing of the fabric 3 more uniform.

[0024] In this embodiment, the upper end of the baffle buffer tube is provided with a V-shaped upper wall 14, which partially overlaps with the side view projection of the output port of the arc-shaped guide tube 13. The V-shaped upper wall 14 can withstand the upper impact of the high-speed fabric 3, and together with the tube wall, it forms a wrapping buffer space, so that the fabric 3 disperses after the collision and flows downwards to avoid the fabric 3 splashing upwards and rolling up. A first inclined surface 15 is provided at the lower end of the baffle buffer tube. The space between the first inclined surface 15 and the end of the upper wall 14 away from the arc-shaped guide tube 13 forms a funnel mouth. After the fabric 3 is decelerated by the collision, it slides smoothly along the first inclined surface 15 into the funnel mouth, so that the fabric 3 continues to unfold at the funnel mouth and enters the funnel tube 16.

[0025] It is worth noting that in this embodiment, the inlet 12, the buffer tube, and the trumpet tube 16 form an independent fabric unfolding cavity. A dyeing solution cavity 11 is provided inside the liquid inlet cylinder 10, and an inlet 19 is opened on the outer side of the liquid inlet cylinder 10. A dyeing solution circulation pump is connected to the inlet 19. A first through-hole 190 is opened at the upper end of the trumpet tube 16, connecting the fabric unfolding cavity and the dyeing solution cavity 11. Dyeing solution continuously enters the dyeing solution cavity 11, and after filling the cavity, it is continuously output from the first through-hole 190. The high-temperature dyeing solution in the dyeing solution cavity 11 continuously flows downwards into the fabric unfolding cavity through the first through-hole 190. When the fabric 3 is buffered and unfolded into the trumpet tube 16, it is simultaneously washed and spread out by fresh dyeing solution. The trumpet tube 16 adopts a gradually expanding diameter, with the diameter gradually increasing from the buffer tube towards the first shaping groove 17. During the forward flow of the dyeing solution, a diffusion phenomenon occurs, further expanding the fabric 3.

[0026] The end of the horn tube 16 is connected to a first shaping groove 17 that slopes downwards. The bottom of the first shaping groove 17 is a second inclined surface, and multiple first ribs 18 are arranged parallel to the fabric 3 conveying direction on the second inclined surface. The rear end of the first shaping groove 17 is connected to a second shaping groove 22 in the fabric storage cylinder 20. The bottom of the second shaping groove 22 is a third inclined surface that slopes downwards, and a second rib 23 is provided on the third inclined surface. The lower ends of the second and third inclined surfaces form an angle α, which is 175°. The two inclined surfaces transition smoothly. The first ribs 18 and the second ribs 23 suspend the bottom of the fabric 3, allowing the dye liquor to pass through the upper and lower sides of the fabric. The dye liquor is guided by the inclined surface, causing the fabric 3 to float up and down and move. Under its own weight, it continues to slide downwards and flatten, without any compression or creases.

[0027] The second shaping tank 22 is connected to the storage tank 24 at its end. The dye liquor enters the storage tank 24 and is stored at a certain liquid level. The fabric 3 can be fully immersed in the dye liquor in the storage tank 24 and be dyed. The bottom of the fabric storage tank 20 is provided with a dye liquor recovery chamber 21. The bottom plate of the storage tank 24 is provided with multiple sets of second through holes 28. The dye liquor carrying floating hair and dye residue in the storage tank 24 passes through the second through holes 28 and flows into the dye liquor recovery chamber 21. The bottom of the dye liquor recovery chamber 21 is provided with a dye liquor recovery port 27, which is connected to an external filtration and circulation system to realize the purification and circulation of the dye liquor.

[0028] Example 2 The difference between this second embodiment and the first embodiment is that the included angle α formed by the first shaping groove 17 and the second shaping groove 22 is 170°, which is suitable for heavy woven fabrics. The larger slope drop enhances the gravity spreading effect and avoids the stacking of thick fabrics.

[0029] Example 3 The difference between this embodiment and embodiment one is that the angle α formed by the first shaping groove 17 and the second shaping groove 22 is 178°, the slope transition is smoother, which is suitable for ultra-thin elastic knitted fabrics and avoids the stretching and deformation of the fabric caused by steep slope pulling.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
