The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0028] "Below" and "above" are referenced based on the normal use state of the gradient dyeing device. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0029] In addition, terms such as "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more such features. In the description of the creation of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0030] As Figures 1 to 3 shown, the gradient dyeing device of the present utility model sequentially includes an unwinding assembly (not shown), a dipping tank 1, a liquid reducing assembly 2, and a winding assembly (not shown) from the feeding side to the discharging side. The continuous conveying direction of the dyed part is the X direction. The dipping tank 1 is communicated with a liquid feeding assembly 3. A drying assembly (not shown) is also provided between the liquid reducing assembly 2 and the winding assembly. The function of the drying assembly is to remove the dye solvent in the dyed part until it is dry to fix the color of the dyed part. Conventionally, it is a heating assembly, including but not limited to roll surface heating, air heating, and microwave heating. The degree of liquid reduction of the liquid reducing assembly directly determines the energy consumption of the drying assembly and reduces the retention of the dye solution in the drying assembly.

[0031] The liquid reducing assembly 2 includes extrusion counter rolls 22, and a dyed part channel 21 is arranged between the extrusion counter rolls 22; it also includes a roll cleaning assembly 4, which has a roll cleaning guide 41, a roll cleaning member 42 slidably connected to the roll cleaning guide 41, a distance fine-tuning member 43, and an angle fine-tuning member 44; the roll cleaning member 42 corresponds to the extrusion counter rolls 22 one by one, is arranged on both sides of the dyed part channel 21, and has a wiping surface (not marked) facing the extrusion counter rolls 22; the distance fine-tuning member 43 adjusts the roll cleaning guide 41 to be close to or far from the extrusion counter rolls 22; the angle fine-tuning member 44 adjusts the wiping surface to be concentric with the roll surface of the extrusion counter rolls 22. The distance fine-tuning member 43 includes but is not limited to a cylinder.

[0032] The roll cleaning member 42 is used to clean the dark pigments remaining on the lye assembly 2, preventing color jumps when changing from dark to light colors for the same batch of fabric / yarn or different batch of color-changing fabric / yarn; combined with the fine-tuning member and the angle fine-tuning member, simultaneous cleaning of the extrusion counter rolls is achieved, and the contact area between the wiping surface and the roll surface is flexibly adjusted to improve the roll surface cleaning effect; the wiping surface is concentric with the roll surface of the extrusion counter rolls, increasing the contact area and thus improving the cleaning effect and cleaning efficiency.

[0033] The liquid reducing assembly 2 includes a first unit liquid reducing member 2a and a second unit liquid reducing member 2b arranged at intervals in sequence from the feed side to the discharge side. A first guide roller 11 is provided between the first unit liquid reducing member 2a and the second unit liquid reducing member 2b. The distance from the axis of the first guide roller 11 to the plane where the bottom of the dipping tank 1 is located is greater than the distance from the highest axis of the squeezing pair roller 22 to the plane where the bottom of the dipping tank 1 is located. The first guide roller 11 adjusts its distance to the plane where the bottom of the dipping tank 1 is located through a first lifting member 61. Both the first unit liquid reducing member 2a and the second unit liquid reducing member 2b adjust the gap between the squeezing pair rollers 22 through a second lifting member 62. The squeezing force of the squeezing pair rollers 22 in the second unit liquid reducing member 2b is greater than the squeezing force of the squeezing pair rollers 22 in the first unit liquid reducing member 2a. The first unit liquid reducing member 2a is the first squeezing, and the second unit liquid reducing member 2b is the second squeezing. Compared with single squeezing, during the time interval between the two squeezings, the dye further adsorbs to the yarn, further improving the dyeing rate. Due to space limitations, in order to further improve the dyeing rate, through the first guide roller 11 with adjustable height, the time interval between the two squeezings is extended or shortened, improving the amount of dye adsorbed by the yarn. By adjusting the gap between the squeezing pair rollers 22 through the second lifting member 62, not only the squeezing force and the amount of dyeing liquid are controlled, but also it is suitable for dyed cloths of different thicknesses or yarns of different strengths and yarn diameters.

[0034] In order to simultaneously control the distance between the roller cleaning member 42 and the squeezing pair roller 22, thereby adjusting the wiping force of the wiping surface, the roller cleaning assembly 4 includes a first unit roller cleaning assembly 4a and a second unit roller cleaning assembly 4b. The first unit roller cleaning assembly 4a is arranged on the feed side of the first unit liquid reducing member 2a, and the second unit roller cleaning assembly 4b is arranged on the discharge side of the second unit liquid reducing member 2b. The corresponding roller cleaning guide members 21 of the first unit roller cleaning assembly 4a and the second unit roller cleaning assembly 4b are provided with long and narrow dyeing member through openings 400. The to-be-dyed member can pass through the long and narrow dyeing member through openings 400 smoothly. Figure 1 and Figure 3 The roller cleaning member 42 and the angle fine adjustment member 44 of the second unit roller cleaning assembly 4b are not drawn, and refer to the structure of the first unit roller cleaning assembly 4a.

[0035] In order to simplify the equipment structure, reduce the occupied area of the equipment and the space utilization rate, the liquid inlet assembly 3 is located below the first guide roller 33. The liquid inlet assembly 3 includes a liquid inlet tank 30, a liquid inlet spray head 32 and a liquid inlet pipe 31. The liquid inlet spray heads 32 are communicated with a dyeing liquid solvent source and / or at least one mixed-color dyeing liquid source through their respective liquid inlet pipes 31; the spraying directions of the liquid inlet spray heads 32 face the surface of the liquid inlet tank 30. Among them, the first unit liquid reducing member 2a, the second unit liquid reducing member 2b and the first guide roller 11 are all arranged above the surface of the liquid inlet tank 30.

[0036] To adjust the tilt angle of the liquid inlet tank, a third lifting member is further included. The bottom of the liquid inlet tank 30 is not shown. The liquid inlet tank 30 is integrally connected to the dipping tank 1 and separated by a first baffle 101. The end of the liquid inlet tank 30 is connected to the third lifting member. A second baffle 102 is provided at the end of the dipping tank 1 and connected to a receiving tank 10. The integration of the liquid inlet tank 30 and the dipping tank 1 can achieve the effect of simplifying the structure, and can also adjust the spreading area of the item to be dyed during dyeing, and can visually observe the dyeing situation in the dipping tank. Through the third lifting member, not only can the flow direction of the dye solution be adjusted, but the dye solution can also be evenly mixed. A roller 100 for the item to be dyed is provided in the dipping tank 1. To be suitable for accommodating the dye solution in an inclined state, the height of the side wall of the dipping tank 1 gradually increases from the discharging side to the feeding side. The receiving tank 10 is for collecting the unused dye and can be recycled. The connection or disconnection between the dipping tank 1 and the receiving tank 10 is adjusted by the second baffle 102, and the connection or disconnection between the dipping tank 1 and the liquid inlet tank 30 is adjusted by the first baffle 101. When switching to another dye after one color is dyed, the dipping tank 1 and the receiving tank 10 are connected, and the original solution is collected first. A liquid outlet is also provided at the bottom of the receiving tank 10. Then the dipping tank 1 and the liquid inlet tank 30 are connected, and after the dipping tank 1 is washed with clean water, the cleaning liquid is discharged through the receiving tank 10. The dipping tank 1 and the receiving tank 10 are disconnected, and another dye is released. Then the dipping tank 1 and the liquid inlet tank 30 are disconnected to complete the dyeing process of the gradient color.

[0037] As Figure 2 shown, the angle fine-tuning member 44 includes a first connecting rod 441 and a second connecting rod 442 connected by a rotating shaft 40.

An arc-shaped guide member 440 is provided on one of the first connecting rod 441 and the second connecting rod 442, and a fixing member (not shown) for fixing the rotation angle of the first connecting rod 441 and the second connecting rod 442 along the arc-shaped guide member 440 is provided on the other. A diagonal brace (not labeled) is provided between the first connecting rod 441 and the slider of the cleaning roller guide member 41. The fixing member is a locking nut. The fixing member passes through the arc-shaped guide member and is connected by a nut, thereby fixing the forked angle of the first connecting rod 441 and the second connecting rod 442. Further, the cleaning roller member 42 includes a wiping layer. The wiping layer is soft, and the surface of the wiping layer facing the squeezing pair of rollers 22 is the wiping surface. The cleaning roller member 42 is connected to the second connecting rod 442 through an elastic member (not labeled).

[0038] In some other embodiments, in order to prevent the dripping of undried dyes on the dyed cloth or yarn from contaminating the liquid inlet nozzle and splashing everywhere, a barrier member 5 is provided between the liquid inlet assembly 3 and the first guide roller 11. The barrier member 5 includes an arc-shaped support rod (not labeled) and a transparent film (not labeled).

The transparent film includes, but is not limited to, polyethylene film, polypropylene film, and PET film. The use of the transparent film can not only observe the liquid inlet condition of the liquid inlet assembly, but also the flexible transparent film has a buffering effect on the dripping dye solution to prevent splashing everywhere.
