Description

Technical Field

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

[0002] Fabric dyeing is an important process in textile processing. Overflow dyeing machines and airflow dyeing machines are commonly used dyeing equipment for knitted and woven fabrics. The dyeing nozzle, as the core component of the dyeing machine, directly determines the atomization effect of the dye liquor, the fabric conveying status, and the final dyeing quality.

[0003] Existing conventional fabric dyeing nozzles mostly employ a single spray structure. During continuous conveying and dyeing, fabric is prone to wrinkling and overlapping due to compression and uneven airflow distribution. Furthermore, traditional nozzles exhibit poor coordination between dye spraying and pneumatic conveying, resulting in uneven dye adhesion and inconsistent color depth in certain areas. In addition, most nozzles lack differentiated sealing designs for the nozzle structure. When air and liquid are discharged from the entire annular nozzle area, the airflow tends to diffuse outwards, failing to centrally comb and loosen the fabric, making it difficult to eliminate wrinkles and significantly impacting the quality of the finished fabric. Summary of the Invention

[0004] In order to overcome the defects of the prior art, the present invention provides a dyeing nozzle device for a dyeing machine and a dyeing machine, which aims to solve the problems of easy wrinkling of fabric, uneven dyeing and poor airflow guidance effect in the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a dyeing nozzle device for a dyeing machine, comprising a fabric feeding assembly, a fabric lifting wheel assembly, a multi-stage spray dyeing guide assembly, and a fabric outlet pipe; The fabric feeding assembly includes a fabric feeding section and a sealing tube. The sealing tube is sleeved outside the fabric feeding section and together they enclose a wetting chamber. The wetting chamber is connected to the upper port of the fabric feeding section and the inside of the fabric lifting wheel assembly. The fabric lifting wheel assembly includes a fabric lifting wheel housing and a fabric lifting wheel disposed therein, and the upper end of the fabric feeding section is connected to the lower end of one side of the fabric lifting wheel housing; The multi-stage spray dyeing guide assembly is located inside the spray dyeing pipe and includes a second guide pipe, a first guide pipe, and a third guide pipe that are sequentially fitted together along the fabric conveying direction. The second guide pipe is connected to the output end of the fabric lifting wheel housing. A first dyeing liquid nozzle and a second dyeing liquid nozzle are respectively formed between two adjacent guide pipes. The first dyeing liquid nozzle is connected to the dyeing liquid chamber between the first guide pipe and the spray dyeing pipe, and the second dyeing liquid nozzle is connected to the air pressure spray chamber between the third guide pipe and the spray dyeing pipe. The fabric outlet pipe is installed at the end of the dyeing pipe away from the fabric lifting wheel housing. The fabric outlet pipe and the third guide pipe form a circular third dyeing liquid nozzle. The third dyeing liquid nozzle is connected to the ventilation pressure spray chamber, and the lower part of the third dyeing liquid nozzle is a sealed structure.

[0006] In the above-mentioned dyeing nozzle device for a dyeing machine, the inner wall of the sealing tube and the outer wall of the fabric feeding section form the wetting chamber, the wetting chamber is directly connected to the upper port of the fabric feeding section, and a liquid inlet pipe is provided on one side of the wetting chamber.

[0007] In the above-mentioned dyeing nozzle device for a dyeing machine, the first guide tube is sleeved on the second guide tube, and the two form the first dye liquor nozzle; one end of the third guide tube is sleeved on the other end of the first guide tube, and the two form the second dye liquor nozzle; a dye liquor inlet is connected to one side of the dye liquor chamber; an atomizing nozzle is provided in the air pressure spray chamber; both the atomizing nozzle and the dye liquor inlet are connected to the dye liquor pipe; and a blower pipe is also connected to the air pressure spray chamber.

[0008] In the above-mentioned dyeing nozzle device for a dyeing machine, the second guide tube is in the shape of a trumpet tube, and a first wide-mouth section is provided at one end of the first guide tube near the second guide tube. The first wide-mouth section is sleeved on the outside of the second guide tube, and the diameter of the openings of the second guide tube and the first wide-mouth section gradually increases from the first guide tube toward the lifting wheel housing.

[0009] In the dyeing nozzle device of the dyeing machine described above, the second guide tube is placed at one end of the first wide-mouth section, and is located in the middle position inside the first wide-mouth section.

[0010] In the above-mentioned dyeing nozzle device for a dyeing machine, a first guide ring is provided on the outer wall of the first guide tube near the third guide tube, and a second wide-mouth section is provided on the end of the third guide tube near the first guide ring. The second wide-mouth section is sleeved on the outside of the first guide ring, and the inner diameters of the second wide-mouth section and the first guide ring gradually increase from the third guide tube toward the first guide tube.

[0011] In the dyeing nozzle device of the dyeing machine described above, the inner diameter of the third guide tube gradually decreases from the outlet tube toward the first guide tube.

[0012] In the above-mentioned dyeing nozzle device for a dyeing machine, a second guide ring is sleeved on one end of the third guide tube near the outlet tube. The outer wall of the second guide ring is an inclined surface, and the third dyeing liquid nozzle is formed between the inclined surface and the outlet tube, so that the airflow of the third dyeing liquid nozzle is guided to the center of the outlet tube.

[0013] In the fabric dyeing nozzle device of the aforementioned dyeing machine, a sealing plate is provided at the lower part of the annular third dye liquor nozzle.

[0014] A dyeing machine includes a dyeing nozzle device as described above, and also includes a dyeing vat, wherein the infeed section and the outlet pipe are respectively installed and connected to the dyeing vat.

[0015] The beneficial effects of this invention are as follows: the dye liquor pre-wets the fabric through the wetting chamber, completing the pre-wetting and improving the subsequent dye liquor adsorption effect; the lifting wheel inside the lifting wheel housing pulls and conveys the fabric, smoothly feeding the fabric into the second guide tube inside the spraying pipe; the dye liquor is respectively sent into the dye liquor chamber and the air pressure spray chamber; the dye liquor in the dye liquor chamber is sprayed out from the first dye liquor nozzle, completing the first spraying; the dye liquor in the air pressure spray chamber is atomized and sprayed out from the second dye liquor nozzle with the high-pressure airflow, realizing atomized spraying, and the dye liquor and fabric... With the materials in full contact, the fabric continues to travel to the annular third dye spray nozzle between the third guide pipe and the outlet pipe. Because the lower part of the third dye spray nozzle is a sealed structure, the high-pressure airflow and dye are sprayed only from the upper and side parts of the annular nozzle towards the center of the outlet pipe, so that the airflow is concentrated and blown towards the center of the fabric, blowing open and loosening the stacked and wrinkled fabric. At the same time, these blown-open wrinkles are atomized and dyed, so that the fabric completes the final spray dyeing in a relaxed state. Then, it flows back to the dyeing vat through the outlet pipe to complete the cycle dyeing. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Combination Figures 1 to 7 The dyeing machine shown includes a dyeing vat 1 and a dyeing nozzle device installed on the dyeing vat 1. The dyeing nozzle device serves as the fabric conveying and dyeing component of the dyeing machine, realizing the integrated operation of continuous conveying, pre-wetting, multi-stage dyeing, and airflow spreading of the fabric 2.

[0026] Specifically, in this embodiment, the dyeing nozzle device is mounted on the upper part of the dyeing vat 1 and forms a circulation path. The dyeing nozzle device is composed of a fabric feeding assembly, a fabric lifting wheel assembly, a dyeing spray pipe 22, a multi-stage dyeing guide assembly, and a fabric outlet pipe 24 connected in series along the fabric conveying direction. The fabric 2 is drawn out from inside the dyeing vat 1, passes through the fabric feeding section 20, the fabric lifting wheel housing 21, the multi-stage dyeing guide assembly, and the fabric outlet pipe 24 in sequence, and then flows back into the dyeing vat 1 to form a closed-loop circulating dyeing circuit. The fabric feeding assembly includes a fabric feeding section 20 and a sealing tube 23. The sealing tube 23 is coaxially sleeved on the outside of the fabric feeding section 20. The inner wall of the sealing tube 23 and the outer wall of the fabric feeding section 20 form an annular wetting chamber. A liquid inlet pipe 201 is provided on one side of the wetting chamber. The wetting chamber is directly connected to the upper port of the fabric feeding section 20, ensuring that after the dye liquid in the chamber is filled, it can flow back into the fabric feeding section 20 and come into contact with the fabric 2. During the upward conveying of the fabric 2, the dye liquid flows back downward, forming mutual collisions to improve the pre-wetting effect of the fabric 2 and enhance the uniformity of subsequent dye liquid adhesion.

[0027] The upper end of the fabric feeding section 20 is fixedly connected to the lower end opening on one side of the fabric lifting wheel housing 21, so as to achieve seamless connection between the fabric feeding assembly and the fabric lifting wheel assembly.

[0028] The fabric lifting wheel assembly includes a lifting wheel housing 21 and a lifting wheel 210 rotatably installed inside the lifting wheel housing 21. The lifting wheel 210 is an active traction component that pulls the fabric 2 forward by relying on rotational friction. After the pre-wetted fabric 2 enters the lifting wheel housing 21, it is clamped, pulled, and smoothly transported by the lifting wheel 210 into the second guide tube 221 inside the rear dyeing tube 22. The lifting wheel housing 21 also serves as a transition cavity to ensure smooth transport of the fabric 2.

[0029] The dyeing tube 22 is a hollow tubular body. Inside it, along the conveying direction of the fabric 2, the second guide tube 221, the first guide tube 220, and the third guide tube 222 are arranged coaxially. The three guide tubes are connected in sequence to form a multi-stage dyeing guide assembly.

[0030] The first guide tube 220 is sleeved on the outside of the second guide tube 221, and the gap between the walls of the two tubes forms an annular first dye liquor nozzle. The outer wall of the first guide tube 220 and the inner wall of the dye spraying tube 22 together form an annular dye liquor chamber 226. A dye liquor inlet 224 is opened on the side wall of the dye liquor chamber 226, and a dye liquor pipe 225 is connected to the dye liquor inlet 224. The dye liquor is continuously introduced into the dye liquor chamber 226 through the dye liquor pipe 225 and the dye liquor inlet 224, and finally sprayed radially onto the fabric surface from the first dye liquor nozzle, completing the first direct spray dyeing.

[0031] One end of the third guide tube 222 facing the first guide tube 220 is sleeved on the other end of the first guide tube 220 away from the second guide tube 221, and the gap between the two tube walls forms an annular second dye spray nozzle; the outer wall of the third guide tube 222 and the inner wall of the spray tube 22 enclose each other to form a wind pressure spray chamber 227.

[0032] An atomizing nozzle 2221 is fixedly installed inside the air pressure spray chamber 227, and the atomizing nozzle 2221 is also connected to the dye liquor pipe 225. The top side wall of the air pressure spray chamber 227 is connected to the blower pipe 223, and the external high-pressure airflow is sent into the air pressure spray chamber 227 through the blower pipe 223. The dye liquor is fully atomized under the action of the atomizing nozzle 2221. The atomized dye liquor is surrounded and constrained by the high-pressure airflow continuously introduced into the air pressure spray chamber 227. The high-pressure airflow mixed with the atomized dye liquor is stably delivered to the second dye liquor nozzle and sprayed out to complete the atomized dyeing, thereby enhancing the dye liquor penetration effect.

[0033] The fabric outlet pipe 24 is installed at the end of the dyeing pipe 22 away from the fabric lifting wheel housing 21. The fabric outlet pipe 24 and the third guide pipe 222 form a ring-shaped third dyeing liquid nozzle. The third dyeing liquid nozzle is connected to the ventilation pressure spray chamber 227, and the lower part of the third dyeing liquid nozzle is a sealed structure. The high-pressure airflow and dyeing liquid are sprayed from the upper and side parts of the third dyeing liquid nozzle toward the center of the fabric outlet pipe 24, so that the airflow is concentrated and blown toward the center of the fabric, blowing open and loosening the stacked and wrinkled fabric. At the same time, the blown-open wrinkles are atomized and dyed, so that the fabric 2 completes the final dyeing in a stretched state.

[0034] The second guide tube 221 adopts a trumpet-shaped structure, with its diameter gradually increasing towards the lifting wheel housing 21. The first guide tube 220, near the end of the second guide tube 221, has an integrally formed first wide-mouth section 2201, which also has a wide-mouth structure, with its diameter gradually increasing towards the lifting wheel housing 21. The first wide-mouth section 2201 is coaxially sleeved on the outside of the second guide tube 221, and the end of the second guide tube 221 is suspended at the center inside the first wide-mouth section 2201. The gap between the first wide-mouth section 2201 and the second guide tube 221 forms a first dye liquor nozzle, allowing the dye liquor to be sprayed out from the first dye liquor nozzle and buffered within the first wide-mouth section 2201. The fabric 2 is then transported within the tube, allowing the dye liquor to further impregnate within the first wide-mouth section 2201. Since the first dye spray nozzle is narrower than the first wide section 2201, the dye can be pressurized and sprayed into the first wide section 2201, so that the dye can be buffered and dispersed in the relatively large space within the first wide section 2201, thereby better dyeing the fabric 2.

[0035] An annular first guide ring 2202 is integrally fixed to the outer wall of the end of the first guide tube 220 near the third guide tube 222; a second wide-mouth section 2220 is integrally formed at the end of the third guide tube 222 facing the first guide tube 220, and the second wide-mouth section 2220 is coaxially sleeved on the outside of the first guide ring 2202. Both the second wide-mouth section 2220 and the first guide ring 2202 adopt a gradually changing inner diameter design, with the inner diameter gradually increasing from the third guide tube 222 towards the first guide tube 220, forming a smoothly transitioning guide surface.

[0036] The third guide tube 222 has a gradually decreasing diameter structure, with its inner diameter gradually decreasing from the end near the outlet tube 24 to the end near the first guide tube 220, forming a tapered tube structure that is larger at the front and smaller at the back. This structure can gradually increase the space for the fabric after two stages of spray dyeing, preparing it for the subsequent airflow combing process.

[0037] The fabric outlet pipe 24 is fixedly installed at the end of the dyeing spray pipe 22 away from the fabric lifting wheel housing 21, and is arranged coaxially with the dyeing spray pipe 22. The outer side of the third guide pipe 222 near the fabric outlet pipe 24 is coaxially sleeved with the second guide ring 2222. The outer circular surface of the second guide ring 2222 is processed into a continuous inclined surface. The inclined surface and the inner wall of the fabric outlet pipe 24 together form a complete ring-shaped third dyeing liquid nozzle. The third dyeing liquid nozzle is interconnected with the front air pressure spray chamber 227, and the high-pressure airflow and atomized dyeing liquid can directly enter the third dyeing liquid nozzle.

[0038] Guided by the inclined surface of the second guide ring 2222, the airflow from the third dyeing nozzle converges and sprays with the dyeing liquid in the direction of the central axis of the fabric outlet pipe 24, using directional airflow to blow and comb the fabric.

[0039] At the lower part of the annular third dye liquor nozzle, a sealing plate 2223 is fixedly installed. The sealing plate 2223 completely seals the lower half of the third dye liquor nozzle, leaving only the upper part and the left and right sides of the nozzle open for air and liquid to flow out. This partial sealing structure is the core design of this device: the high-pressure airflow and atomized dye liquor in the wind pressure spray chamber 227 are sprayed from the upper part and the sides of the third dye liquor nozzle towards the center, with no airflow overflowing from the lower part, greatly improving the concentration of airflow; the directional and converging airflow continuously acts on the fabric surface, which can completely blow away the wrinkles and folds caused by compression and stacking during the transportation process, keeping the fabric in a loose and relaxed state, fundamentally reducing dyeing wrinkle defects.

[0040] In this embodiment, fabric 2 is drawn out from inside the dyeing vat 1 and enters the fabric feeding section 20. The liquid inlet pipe 201 delivers dye liquor to the soaking chamber, and the fabric is pre-soaked during its passage. The pre-soaked fabric 2 enters the fabric lifting wheel housing 21 and is pulled forward by the fabric lifting wheel 210, smoothly fed into the dye spray pipe 22. Fabric 2 passes through the second guide pipe 221 and the first guide pipe 220 in sequence. The dye liquor in the dye liquor chamber 226 is sprayed out from the first dye liquor nozzle, completing the first dye spray. Fabric 2 enters... In the third guide pipe 222 area, the atomized dye liquid in the wind pressure spray chamber 227 is sprayed out from the second dye liquid nozzle with the high pressure airflow to achieve atomized penetration dyeing; when the fabric 2 moves to the position of the third dye liquid nozzle, because the lower part of the nozzle is sealed by the sealing plate 2223, the airflow and atomized dye liquid converge and spray from the top and sides towards the center, blowing away the fabric wrinkles and completing the last spray dyeing at the same time; the stretched fabric 2 flows back into the dyeing vat 1 through the fabric outlet pipe 24 to enter the next round of repeated cycle dyeing.

[0041] 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.
