Description

Technical Field

[0001] The present invention relates to a dyeing machine, and more particularly to a tubular air-liquid dyeing machine. Background Art

[0002] Currently, most of the low liquor ratio dyeing machines are tank dyeing machines. The tank dyeing machine has the characteristic of low liquor ratio. However, due to its structural form, the fabric to be dyed is subjected to a relatively greater force of stacking and extrusion in the fabric storage tank of the tank dyeing machine. Therefore, for some fabrics that are sensitive to extrusion stress, it is relatively easy to produce stacking marks or fine creases, resulting in poor dyeing of the fabric.

[0003] Most of the traditional methods to solve the above problems are to reduce the fabric loading amount. Reducing the fabric loading amount can indirectly increase the dyeing bath ratio. Another method is to use a tubular dyeing machine with a large liquor ratio. However, the above methods are all contrary to the current environmental policies and the energy conservation and environmental protection direction of dyeing and finishing equipment.

[0004] The tank air-liquid dyeing machines that have emerged in recent years can, to a certain extent, solve the crease problem of some fabrics during the dyeing process. However, since the existing air-liquid dyeing machines are all of tank structure, the stacking and extrusion force of the fabric in the fabric storage tank is still relatively large, and the internal stress of the fabric cannot be released well. Therefore, the existing tank air-liquid dyeing machines still cannot avoid the problem of poor dyeing caused by creases for some fabrics, especially long fiber high count high density fabrics or multi-component fabrics. Summary of the Invention

[0017] Implementing the embodiments of the present invention has the following beneficial effects:

[0018] 1. The tubular air-liquid dyeing machine of the present invention has a horizontally arranged tubular structure. Since the tubular structure has a larger unfolding space, the cylinder of the tubular structure is more suitable for the flow of long-fiber high-count high-density fabrics and multi-component fabrics inside it. The fabric is subjected to relatively less stacking and extrusion forces in the fabric storage tank of the tubular air-liquid dyeing machine. Therefore, the tubular air-liquid dyeing machine of the present invention can effectively reduce the internal stress generated by the fabric, especially long-fiber high-count high-density fabrics and multi-component fabrics, in the storage tank, reduce the generation of stacking marks and fine creases, and thus improve the dyeing quality.

[0019] 2. The tubular air-liquid dyeing machine is provided with a rear nozzle, and the rear nozzle is provided with an air outlet mechanism, or a dye liquor spraying mechanism, or both an air outlet mechanism and a dye liquor spraying mechanism. The air outlet mechanism and the dye liquor spraying mechanism can be flexibly combined, enabling the tubular air-liquid dyeing machine to be suitable for different fabrics in different dyeing and finishing processes. Therefore, the tubular air-liquid dyeing machine of the present invention also has the advantage of a wide range of applicable fabric varieties.

[0020] 3. A first guiding arc surface and a second guiding arc surface are respectively provided inside the fabric return tank and the fabric feeding tank of the tubular air-liquid dyeing machine. The return fabric pipe section and the main pipe section are both inclined downward along the fabric moving direction, ensuring that the fabric can flow smoothly to the fabric feeding pipe section. And the fabric feeding pipe section is inclined upward along the fabric moving direction, ensuring that the tubular air-liquid dyeing machine can operate smoothly at a low bath ratio. Therefore, the tubular air-liquid dyeing machine of the present invention also has the advantage of smooth fabric operation.

[0021] 4. The tubular air-liquid dyeing machine is provided with a blower, which is used to draw the air in the main cylinder into the air outlet mechanism of the air nozzle and / or the rear nozzle. The fabric is driven to move by the air flow generated by the blower. Therefore, when the tubular air-liquid dyeing machine operates, it does not require more dye liquor to drive the fabric, and the dye liquor is only used for dyeing.

[0022] 5. The tubular air-liquid dyeing machine is provided with a fabric distributing hopper and a swinging mechanism. The fabric distributing hopper has a third guiding arc surface. Therefore, the tubular air-liquid dyeing machine of the present invention can ensure that the fabric is stacked neatly during operation, thereby increasing the fabric loading capacity of the equipment and reducing the dyeing water ratio.

[0024] Figure 2 is the left view direction schematic diagram of the first embodiment of the tubular air-liquid dyeing machine of the present invention;

[0025] Figure 3 is the overall structural schematic diagram of the first embodiment of the tubular air-liquid dyeing machine of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0026] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the terms of orientation such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention and do not specifically limit the present invention.

[0027] See Figure 1 , the first embodiment of the present invention discloses a tubular air-liquid dyeing machine, which includes a main cylinder body 1, a cloth lifting device 2, an air nozzle 3, a cloth running pipe 4 and a cloth arranging device 6. The main cylinder body 1 is a horizontally arranged tubular structure, wherein the heights of both ends of the main cylinder body 1 are higher than that of the middle part, and the fabric moves along the axial direction of its tubular structure inside the main cylinder body 1. A cloth storage tank 5 is arranged inside the main cylinder body 1, and the cloth storage tank 5 is used for the fabric to move within its space. The cloth lifting device 2 is arranged on the top of the main cylinder body 1 and is used to lift the fabric from the cloth storage tank 5 and make it enter the cloth running pipe 4. The cloth lifting device 2 is sequentially connected to the air nozzle 3, the cloth running pipe 4 and the cloth arranging device 6, and the bottom surface of the cloth storage tank 5 gradually slopes upward along the moving direction of the fabric.

[0028] The tubular air-liquid dyeing machine of the present invention is a horizontally arranged tubular structure. Since the tubular structure has a larger unfolding space, the cylinder body of the tubular structure is more suitable for the flow of long-fiber high-count high-density fabrics and multi-component fabrics inside it than the cylinder body of the tank-like structure. The acting force of the fabric being stacked and squeezed in the cloth storage tank 5 of the tubular air-liquid dyeing machine is relatively smaller.

[0029] As can be seen from the above, the tubular air-liquid dyeing machine of the present invention can effectively reduce the internal stress generated by the fabric, especially long-fiber high-count high-density fabrics and multi-component fabrics, in the cloth storage tank 5, and reduce the generation of stacking marks and fine creases, thus having the advantage of high dyeing quality.

[0030] The tubular air-liquid dyeing machine further includes a rear nozzle 7, which is arranged between the fabric conveying pipe 4 and the fabric distributing device 6. The rear nozzle 7 is provided with an air outlet mechanism and a dye liquor spraying mechanism at the same time. When the fabric to be dyed and finished is suitable for being driven by wind, the air outlet mechanism is started to drive the fabric. When the fabric to be dyed and finished is suitable for being driven by water, the dye liquor spraying mechanism is started to drive the fabric. Driving the fabric by using the air outlet mechanism will make the water bath ratio in the tubular air-liquid dyeing machine lower. In different embodiments, the rear nozzle 7 can be provided with only the air outlet mechanism, or only the dye liquor spraying mechanism, or a combined dye liquor spraying mechanism capable of spraying air and dye liquor in a certain proportion. When only the air outlet mechanism is provided, the structure of the rear nozzle 7 is relatively simple, convenient to maintain, with low use cost, and is suitable for dyeing and finishing fabrics driven by wind or requiring a low dyeing water ratio; when only the dye liquor spraying mechanism is provided, it is suitable for dyeing and finishing fabrics driven by water; while the structure of the rear nozzle with the combined dye liquor spraying mechanism is relatively complex and the maintenance cost is also high, but the dye liquor and air can be mixed and sprayed out at the same time. Users can flexibly select according to their needs, making the tubular air-liquid dyeing machine applicable to different fabrics in different dyeing and finishing processes, having the advantages of flexible use and a wide variety of applicable fabrics.

[0031] The main cylinder body 1 includes a fabric return pipe section 11, a main pipe section 12 connected to the fabric return pipe section 11, and a fabric feeding pipe section 13 connected to the main pipe section 12. The fabric return pipe section 11 is connected to the fabric distributing device 6, and the fabric feeding pipe section 13 is connected to the fabric lifting device 2. The fabric moves from the fabric return pipe section 11 to the fabric feeding pipe section 13. Both the fabric return pipe section 11 and the main pipe section 12 are arranged to slope downward along the fabric moving direction. Therefore, the height of the fabric return pipe section 11 is higher than that of the main pipe section 12. The fabric feeding pipe section 13 is arranged to slope upward along the fabric moving direction. Therefore, the height of the fabric feeding pipe section 13 is higher than that of the main pipe section 12. The storage trough 5 includes a fabric return trough 53 located in the fabric return pipe section 11, and a first guiding arc surface 531 is provided on the fabric return trough 53; a main storage trough 51 located in the main pipe section 12, and the main storage trough 51 slopes downward along the fabric moving direction; a fabric feeding trough 52 located in the fabric feeding pipe section 13, and a second guiding arc surface 521 is provided on the fabric feeding trough 52.

[0032] Both the fabric return pipe section 11 and the main pipe section 12 are arranged to slope downward along the fabric moving direction. At the same time, a first guiding arc surface 531 is provided in the fabric return trough 53, ensuring that the fabric can flow smoothly to the fabric feeding pipe section 13. While the fabric feeding pipe section 13 slopes upward along the fabric moving direction, and a second guiding arc surface 521 is provided in the fabric feeding trough 52, enabling the fabric to move obliquely upward along the moving direction on the second guiding arc surface 521. This not only enables the same mass of dye liquor to obtain a higher water level, but also alleviates the accumulation of the fabric in the fabric feeding pipe section 13 to a certain extent. Therefore, the embodiment of the present invention also has the advantage that the fabric runs smoothly at a low bath ratio.

[0033] The tubular air-liquid dyeing machine further includes a dye liquor spraying and supplying mechanism 8, which is used to spray the heated dye liquor into the fabric circulation waterway. The dye liquor spraying and supplying mechanism 8 includes a main water pump 81, a filtering device 82 and a heat exchanger 83 connected in sequence; the main water pump 81 is used to pump the dye liquor at the bottom of the main cylinder 1 into the filtering device 82, the filtering device 82 is used to filter the dye liquor supplied by the main water pump 81, and the heat exchanger 83 is used to heat the dye liquor filtered by the filtering device 82 to a predetermined temperature and introduce it into the dye liquor spraying mechanism of the rear nozzle 7.

[0034] A blower 9 is provided at one end of the main cylinder 1. When the rear nozzle 7 is provided with a dye liquor spraying mechanism or a combined dye liquor spraying mechanism, the blower 9 is used to pump the air in the main cylinder 1 into the air nozzle 3. When the rear nozzle 7 is only provided with an air outlet mechanism, the blower 9 will introduce air into the air nozzle 3 and the air outlet mechanism of the rear nozzle 7. At this time, the fabric is driven to run by the air flow generated by the blower 9. Therefore, more dye liquor is not needed to drive the fabric during operation, and the dye liquor is only used for dyeing. Therefore, the embodiment of the present invention also has the characteristics of low dyeing water ratio, energy saving and environmental protection.

[0035] The arranging device 6 includes an arranging hopper 61 and a swinging mechanism 62. The arranging hopper 61 has a third guiding arc surface 611. The third guiding arc surface 611 is preferably located directly in front of the fabric ejection outlet and is inclined towards the direction of the fabric return trough 53. Therefore, after the fabric is ejected, it first hits the third guiding arc surface 611, and then moves down along the arc surface of the third guiding arc surface 611 to the fabric return trough 53. The setting of the third guiding arc surface 611 can ensure that the fabric is neatly stacked on the fabric return trough 53 during operation. Therefore, the embodiment of the present invention also has the advantages of neat fabric stacking and large fabric loading capacity.

[0036] The arranging hopper 61 is connected to the swinging mechanism 62, and the swinging mechanism 62 can drive the arranging hopper 61 to swing back and forth. The swinging mechanism 62 preferably uses a swing drive motor for driving. The swing drive motor is used to drive the arranging hopper 61 to swing through its own rotation. Using a swing drive motor has the advantage of high efficiency, but it will make the structure of the arranging device 6 complex. The swinging mechanism 62 can also use a hand-cranked swing arm for driving. The hand-cranked swing arm is used to drive the arranging hopper 61 to swing manually. Using a hand-cranked swing arm will make the structure of the arranging device 6 slightly simpler and more flexible to adjust.

[0037] Such as Figure 3As shown in the figure, according to the second embodiment of the present invention, the difference from the first embodiment is that the tubular air-liquid dyeing machine further includes a front nozzle 10, and the front nozzle 10 is arranged between the main cylinder body 1 and the cloth lifting device 2. The front nozzle 10 is also connected to the dye liquor spraying and supplying mechanism 8 for spraying the dye liquor on the fabric when the cloth lifting device 2 lifts the fabric. By adopting this embodiment, the front nozzle 10 can independently realize the dye liquor spraying; or it can cooperate with the rear nozzle 7 to spray the dye liquor on the fabric at two positions during the process of the fabric being lifted from the cloth storage tank 5 and falling back into the cloth storage tank 5, improving the dyeing efficiency and the dyeing fastness.

[0038] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
