[0020] See also Figure 1 and Figure 2 An embodiment of the ultrasonic pre-treatment device for dyeing and finishing of the utility model is suitable for performing a dyeing and finishing pre-treatment process on a grey cloth 9, such as a desizing process, a refining process, etc. For simplicity, the subsequent paragraphs are all described by taking the desizing process as an example.

[0021] The embodiment includes a frame 1 , a front oscillating unit 2 , a reaction unit 3 , a rear oscillating unit 4 , a transmission unit 5 , and a water removal unit 6 .

[0022] The frame 1 includes a frame body 11 and a flip cover 12 installed on the top surface of the frame body 11 along a top-to-bottom direction D1.

[0023] The front oscillation unit 2 is disposed on the frame 1 and includes a front nozzle 21, a front ultrasonic oscillator 22 located below the front nozzle 21, and a front inner peripheral wall surface 23 connected to the top surface of the front ultrasonic oscillator 22 along the top-bottom direction D1. The front ultrasonic oscillator 22 and the front inner peripheral wall surface 23 jointly define a front oscillation groove 24.

[0024] The front ultrasonic oscillator 22 is used to simultaneously generate spiral ultrasonic waves of different frequencies to enter the front oscillation groove 24. In this embodiment, the front ultrasonic oscillator 22 adopts a multi-frequency spiral oscillator produced by Honda Motor.

[0025] The front inner wall surface 23 has four front oblique wall surfaces 231 extending upward from the top surface of the front ultrasonic oscillator 22, so that the front oblique wall surfaces 231 and the front ultrasonic oscillator 22 jointly define the front oscillation groove 24 which is gradually expanding upward. It is worth mentioning that, since the front oscillation groove 24 is gradually expanding upward, the ultrasonic waves generated by the front ultrasonic oscillator 22 will contact the front oblique wall surfaces 231, causing the ultrasonic waves reflected by the front oblique wall surfaces 231 to interfere with each other and generate various oscillation waves of different states with different depths, thereby generating a multi-level oscillation effect, and more effectively washing the grey cloth 9.

[0026] In this embodiment, the front oscillation tank 24 is used to accommodate hot water with a water temperature between 60 degrees Celsius and 70 degrees Celsius. An emulsifier can also be added into the front oscillation tank 24 according to actual needs to further produce a chemical reaction with the synthetic slurry on the grey cloth 9 in advance.

[0027] The reaction unit 3 is disposed on the frame 1 and is located behind the front oscillation unit 2 along a front-to-back direction D2. The reaction unit 3 includes a middle nozzle group 31 and a middle tank peripheral surface 32 located below the middle nozzle group 31 and defining a reaction tank 324.

[0028] The middle nozzle group 31 includes two middle nozzles 311 spaced apart from each other along the front-to-back direction D2.

[0029] The middle groove peripheral surface 32 has a rectangular middle bottom wall surface 321 , four middle inclined wall surfaces 322 extending gradually upward from the outer peripheral edge of the middle bottom wall surface 321 , and four middle vertical wall surfaces 323 extending upward from the top edge of the middle inclined wall surface 322 .

[0030] The reaction tank 324 has a lower reaction tank portion 325 defined by the middle bottom wall portion 321 and the middle inclined wall portion 322 and gradually expanding upward, and an upper reaction tank portion 326 located above the lower reaction tank portion 325. In this embodiment, the reaction tank 324 is used to accommodate a washing liquid for chemically reacting with the grey cloth 9, and the washing liquid contains liquid alkali (sodium hydroxide, NaOH), an oxidant, an emulsifier, an oligomer cleaner and water.

[0031] The rear oscillation unit 4 is disposed on the frame 1 and is located between the reaction unit 3 and the water removal unit 6. The rear oscillation unit 4 includes a rear nozzle 41, a rear ultrasonic oscillator 42 located below the rear nozzle 41, and a rear inner surrounding wall surface 43 connected to the top surface of the rear ultrasonic oscillator 42. The rear ultrasonic oscillator 42 and the rear inner surrounding wall surface 43 jointly define a rear oscillation groove 44.

[0032] The rear ultrasonic oscillator 42 is also used to simultaneously generate spiral ultrasonic waves of different frequencies to enter the rear oscillation groove 44. In this embodiment, the rear ultrasonic oscillator 42 is also a multi-frequency spiral oscillator produced by Honda Motor.

[0033] The rear inner wall surface 43 has four rear oblique wall surfaces 431 extending upward from the top surface of the rear ultrasonic oscillator 42, so that the rear oblique wall surfaces 431 and the rear ultrasonic oscillator 42 jointly define the rear oscillation groove 44 which is gradually expanding upward. It is worth mentioning that, since the rear oscillation groove 44 is gradually expanding upward, the ultrasonic waves generated by the rear ultrasonic oscillator 42 will contact the rear oblique wall surfaces 431, causing the ultrasonic waves reflected by the rear oblique wall surfaces 431 to interfere with each other and generate various oscillation waves of different states with different depths, thereby generating a multi-level oscillation effect, and more effectively washing the grey cloth 9.

[0034] In this embodiment, the rear oscillation tank 44 is used to accommodate cold water with a water temperature between 18 degrees Celsius and 35 degrees Celsius. According to actual needs, acetic acid can be added into the rear oscillation tank 44 to further enhance the acid-base neutralization effect.

[0035] The transmission unit 5 is rotatably disposed on the frame 1, and includes a front roller 51, a middle roller group 52, a rear roller 53, an attachment roller 54 located below the middle nozzle group 31 and above the middle roller group 52, a first auxiliary roller 55 located below the front nozzle 21, a second auxiliary roller 56 located behind the first auxiliary roller 55, a third auxiliary roller group 57 located behind the attachment roller 54 and below the rear nozzle 41, a fourth auxiliary roller 58 disposed between the third auxiliary roller group 57 and the dewatering unit 6 along the front-to-back direction D2, and a fifth auxiliary roller 59 disposed between the middle roller group 52 and the third auxiliary roller group 57 along the top-to-bottom direction D1. The third auxiliary roller group 57 has two auxiliary sub-rollers 571 spaced apart from each other.

[0036] The front roller 51 is located in the front oscillation groove 24 and between the front nozzle 21 and the front ultrasonic oscillator 22 along the top-bottom direction D1.

[0037] The middle roller assembly 52 is located in the reaction tank 324 and has a hollow outer cylinder 521 and an inner rotor 525 located in the outer cylinder 521 and rotating in the opposite direction to the outer cylinder 521. The outer cylinder 521 has an inner cylinder surface 522 surrounding the inner rotor 525, an outer cylinder surface 523 opposite to the inner cylinder surface 522, and a plurality of openings 524 penetrating the inner cylinder surface 522 and the outer cylinder surface 523.

[0038] The rear roller 53 is located in the rear oscillation groove 44 and between the rear nozzle 41 and the rear ultrasonic oscillator 42 along the top-bottom direction D1.

[0039] The dewatering unit 6 is rotatably disposed on the frame 1 , and includes two dewatering rollers 61 located behind the rear oscillating unit 4 , and an auxiliary nozzle 62 located in front of the dewatering rollers 61 .

[0040] It should be noted that before the grey cloth 9 is driven to perform the pre-dyeing and finishing procedure, since the hot water, washing liquid and cold water in the front oscillation tank 24, the reaction tank 324 and the rear oscillation tank 44 will be discharged quantitatively, the front nozzle 21 is connected to a front replenishing tank (not shown) for storing hot water via a front pump (not shown in the figure) to quantitatively replenish the hot water contained in the front oscillation tank 24; the middle nozzle group 31 is connected to a middle replenishing tank (not shown) for storing washing liquid via a middle pump (not shown in the figure) to quantitatively replenish the washing liquid contained in the reaction tank 324; the rear nozzle 41 is connected to a rear replenishing tank (not shown) for storing cold water via a rear pump (not shown in the figure) to quantitatively replenish the cold water contained in the rear oscillation tank 44; the auxiliary nozzle 62 is connected to an auxiliary replenishing tank (not shown) for storing cold water via an auxiliary pump (not shown in the figure).

[0041] During actual operation, the grey cloth 9 passes through the front oscillation tank 24 , the reaction tank 324 and the rear oscillation tank 44 in sequence.

[0042] First, before the grey cloth 9 enters the front oscillation tank 24 , the front nozzle 21 assists in spraying the hot water drawn from the front replenishment tank by the front pump, thereby producing the effect of pre-wetting the grey cloth 9 .

[0043] Next, when the grey cloth 9 enters the front oscillation tank 24 and is immersed in hot water, the front ultrasonic oscillator 22 emits ultrasonic waves toward the front oscillation tank 24 to clean the synthetic slurry on the grey cloth 9, such as polyvinyl alcohol (PVA) and polyacrylate (PA).

[0044] Next, after the grey cloth 9 moves out of the front oscillation groove 24 and is attached to the attachment roller 54, the middle nozzle group 31 assists in spraying the washing liquid extracted from the middle replenishing groove by the middle pump, which can not only further flush the synthetic slurry remaining on the grey cloth 9, but also produce a chemical reaction with the grey cloth 9 in advance.

[0045] Next, when the grey cloth 9 enters the reaction tank 324 and is immersed in the washing liquid, the inner rotor 525 rotates in the opposite direction relative to the outer cylinder 521, so that the washing liquid between the inner rotor 525 and the outer cylinder 521 is squeezed and ejected from the opening 524 to form a water column, thereby penetrating the grey cloth 9 with high pressure to enhance the washing effect.

[0046] Next, after the grey cloth 9 moves out of the reaction tank 324 relative to the fifth auxiliary roller 59 and is attached to the third auxiliary roller group 57, the rear nozzle 41 assists in spraying the cold water drawn from the rear replenishing tank by the rear pump, thereby producing the effect of pre-cleaning the grey cloth 9.

[0047] Next, when the grey cloth 9 enters the rear oscillation tank 44 and is immersed in cold water, the rear ultrasonic oscillator 42 emits ultrasonic waves toward the rear oscillation tank 44 to clean and neutralize the synthetic slurry and detergent on the grey cloth 9 through impact.

[0048] Next, after the grey cloth 9 moves out of the rear oscillation tank 44 and is located between the fourth auxiliary roller 58 and the dewatering unit 6, the auxiliary nozzle 62 assists in spraying the cold water drawn from the auxiliary replenishing tank by the auxiliary pump, thereby producing the effect of washing the grey cloth 9 again.

[0049] Finally, the water removal roller 61 squeezes and removes the water in the grey cloth 9 to complete the desizing process.

[0050] See also Figure 1 and Figure 3 , a variation of the ultrasonic pre-treatment device for dyeing and finishing of the utility model (see Figure 3 ), including a plurality of the frames 1, a plurality of the front oscillation units 2, a plurality of the reaction units 3, a plurality of the rear oscillation units 4, a plurality of the transmission units 5, and a plurality of the dewatering units 6. In this variation, the number of the frames 1, the front oscillation units 2, the reaction units 3, the rear oscillation units 4, the transmission units 5, and the dewatering units 6 is three. The variation can define three processing areas W arranged in sequence along the front-to-back direction D2. Each processing area W includes one of the frames 1, one of the front oscillation units 2, one of the reaction units 3, one of the rear oscillation units 4, one of the transmission units 5, and one of the dewatering units 6.

[0051] In actual operation, the grey cloth 9 passes through the processing area W in sequence along the front-to-back direction D2.

[0052] The difference between the variation and the embodiment is not only the number of components mentioned above, but also the difference in the liquids contained in the front oscillation tank 24 , the reaction tank 324 , and the rear oscillation tank 44 .

[0053] The front oscillation tank 24 in the front treatment zone W is used to contain hot water, and an emulsifier can also be added to the front oscillation tank 24 according to actual needs; the reaction tank 324 and the rear oscillation tank 44 in the front treatment zone W are used to contain detergent.

[0054] The front oscillation tank 24, the reaction tank 324 and the rear oscillation tank 44 in the middle section of the processing area W are used to accommodate cleaning liquid.

[0055] The front oscillation tank 24 , the reaction tank 324 and the rear oscillation tank 44 in the treatment zone W of the rear section are used to contain cold water, and acetic acid can also be added to the front oscillation tank 24 according to actual needs.

[0056] In this way, the variation can further improve the desizing effect on the basis of the embodiment. It should be particularly noted that, in response to the different types of fabrics and slurries, technicians in this field can freely adjust the number of the above components according to actual needs, and freely select the liquid contained in the front oscillation tank 24, the reaction tank 324 and the rear oscillation tank 44. This variation is only an example and should not be limited to this.

[0057] Therefore, the embodiment and the variation examples all have the following effects:

[0058] (i) By providing the front oscillation unit 2, the reaction unit 3 and the rear oscillation unit 4, the ultrasonic waves generated by the front oscillation unit 2 and the rear oscillation unit 4 impact the grey cloth 9, thereby maintaining the washing effect while reducing the overall water consumption, or even improving the washing effect. In addition, since the overall water consumption is reduced, the amount of medicine required is also less, and the overall energy consumption is also less.

[0059] (ii) The front nozzle 21, the middle nozzle group 31, the rear nozzle 41 and the auxiliary nozzle 62 are provided to assist in spraying and washing the grey cloth 9, thereby maintaining the washing effect of the desizing process while reducing the overall water consumption.

[0060] (III) By providing the front oscillation groove 24 and the rear oscillation groove 44 which are gradually expanded upward, the ultrasonic waves generated by the front ultrasonic oscillator 22 and the rear ultrasonic oscillator 42 are reflected by the front inclined wall surface 231 and the rear inclined wall surface 431 respectively, which interfere with each other and generate various oscillation waves of different states depending on the depth, thereby generating a multi-level oscillation effect and more effectively washing the grey cloth 9.

[0061] In summary, the water consumption of the ultrasonic pre-treatment equipment for dyeing and finishing of the utility model is significantly reduced, and the purpose of the utility model can indeed be achieved.

[0062] However, the above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
