Description

Technical Field

[0001] This utility model relates to the field of dyeing equipment technology, and in particular to a waterless denim dyeing device with controllable color. Background Technology

[0002] Waterless denim fabric is not a coated fabric, but rather dyed directly using a coating. Compared to dye dyeing, it has advantages such as a shorter process, a wider color spectrum, stronger colorfastness, higher dye uptake, lower cost, lower energy consumption, water conservation, and near-zero emissions. Dyeing equipment is an essential piece of equipment for dyeing fabric, as it can reduce manual labor and improve work efficiency.

[0003] A search revealed Chinese Patent Publication No. CN221460730U, which discloses a dyeing device for denim fabric processing. The device includes a base plate with a dyeing mechanism on its top. The dyeing mechanism includes a rotating rod movably connected to the middle of the top of the base plate, and a turntable fixedly connected to the top of the rotating rod. This dyeing device uses the output of a stirring motor to drive a stirring rod to agitate the dye paste inside the dyeing tank. Simultaneously, a brush plate lifts up the dye paste that has settled at the bottom of the dyeing tank. Then, the output of a servo motor drives a drive gear to rotate. Through the meshing of driven gears, the dyeing tank rotates in the opposite direction, resulting in more uniform mixing of the dye paste. This prevents the dye paste from easily separating and settling after long-term storage, thus solving the problem of separation and settling that can occur with dye paste after prolonged storage.

[0004] Although the dyeing equipment described in the above patent can make the dye paste more evenly mixed, the dyeing color is limited and there are problems such as slow color matching and difficulty in controlling color accuracy. Therefore, it is necessary to design a waterless denim dyeing equipment with controllable color to solve the above problems. Utility Model Content

[0025] Example

[0026] like Figure 1-5 As shown, a color-controllable waterless denim dyeing device includes a housing 1. Fixing seats 2 are fixedly connected to both sides of the upper surface of the housing 1. A dye cylinder 3 is fixedly connected inside the fixing seats 2. A feed pipe 4 is fixedly connected to the upper surface of the dye cylinder 3. A first discharge pipe 5 is fixedly connected to the lower surface of the dye cylinder 3. A flow valve 6 is fixedly connected to the outer surface of the first discharge pipe 5. A mixing cylinder 7 is fixedly connected to the middle of the inner top wall of the housing 1. A motor 8 is fixedly connected to the middle of the upper surface of the housing 1. A rotating rod 9 is fixedly connected to the output end of the motor 8. A stirring blade 10 is fixedly connected to the middle of the outer surface of the rotating rod 9. A colorimeter 11 is fixedly connected to the middle of the front side of the housing 1. A fixing plate 12 is fixedly connected to the middle of the inner side of the housing 1. A color measuring camera 13 is fixedly connected to the lower surface of the fixing plate 12.

[0027] In practical use, the dye cylinder 3, flow valve 6, mixing cylinder 7, stirring blade 10, colorimeter 11, and color measuring camera 13 are arranged. The fixed base 2 supports the dye cylinder 3. Multiple dye cylinders 3 store different single-color dyes, which can be conveyed simultaneously during color matching and dyeing, reducing working steps and color matching time, and speeding up work efficiency. The colorimeter 11 selects the dye color to be prepared, and controls the flow valve 6 at the bottom of the corresponding dye cylinder 3 to open, so that the dye inside the dye cylinder 3 is conveyed to the inside of the mixing cylinder 7 through the first discharge pipe 5. The flow valve 6 automatically closes when the amount of dye flowing through it reaches the preset value for the corresponding color. This allows for more precise color mixing and improves the quality of dyeing. The color measuring camera 13 can photograph and detect the dye after color mixing to ensure color accuracy. Through computer-controlled intelligent color mixing, different pre-dyeing colors can be selected as needed, expanding the range of applications and resulting in high dyeing efficiency and high color accuracy. The motor 8 drives the rotating rod 9 to rotate, causing the stirring blade 10 to mix different single-color dyes and combine them into a pre-dyeing color, thus enhancing the mixing effect.

[0028] In this embodiment, a second discharge pipe 14 is fixedly connected to the lower surface of the mixing cylinder 7, and a solenoid valve 15 is fixedly connected to the outer surface of the second discharge pipe 14.

[0029] In practical use, the opening of the second discharge pipe 14 can be controlled by the solenoid valve 15, thereby controlling the delivery of dye inside the mixing cylinder 7.

[0030] In this embodiment, a connecting pipe 16 is fixedly connected to the bottom of the inner side of the second discharge pipe 14, a fixing pipe 17 is fixedly connected to one end of the connecting pipe 16, and an inkjet head 18 is fixedly connected to the lower surface of the fixing pipe 17.

[0031] In practical use, by setting the inkjet head 18, multiple inkjet heads 18 are fixed on the lower surface of the fixed tube 17. The number of inkjet heads 18 to be used can be controlled according to the width of the fabric, thus enhancing adaptability. The connecting tube 16 delivers the dyed color to the inside of the fixed tube 17, and the fabric is dyed by the inkjet head 18, resulting in uniform coloring.

[0032] In this embodiment, a water inlet pipe 19 is fixedly connected to the top of the outer surface of the mixing cylinder 7, and a control valve 20 is fixedly connected to the outer surface of the water inlet pipe 19. A connecting rod 21 is fixedly connected to the top and bottom of the outer surface of the rotating rod 9, and a scraper 22 is fixedly connected to one end of the connecting rod 21.

[0033] In practical use, by setting up the water inlet pipe 19 and the scraper 22, when it is necessary to change the color for dyeing, the dye inside the mixing drum 7 is emptied, the control valve 20 is used to open the water inlet pipe 19, and external water is delivered to the inside of the mixing drum 7. The scraper 22 scrapes and cleans the inner wall of the mixing drum 7 under the action of the rotating rod 9, so that the mixing drum 7 is cleaned more thoroughly, and then the dye is re-matched.

[0034] In this embodiment, a guide plate 23 is fixedly connected to the inner bottom wall of the housing 1, and a waste discharge pipe 24 is fixedly connected to the bottom of the front side of the housing 1.

[0035] In practical use, the guide plate 23 can guide the wastewater after cleaning the mixing drum 7 through the guide plate 23, and discharge the wastewater to the designated location through the waste discharge pipe 24.

[0036] In this embodiment, a conveying roller 25 is rotatably connected to the bottom of the inner side of the housing 1, a guide rod 26 is slidably connected to the inner side of the housing 1 near the conveying roller 25, a spring 27 is sleeved on the outer surface of the guide rod 26, a bracket 28 is fixedly connected to one end of the guide rod 26, and a pressure roller 29 is rotatably connected to the inner side of the bracket 28.

[0037] In practical use, through the setting of conveyor roller 25 and pressure roller 29, guide rod 26 is slidably connected to the inner wall of housing 1. After the pressure roller 29 is subjected to force, it can drive the guide rod 26 to slide through the bracket 28, thus making it suitable for denim fabrics of different thicknesses within a certain range. Spring 27 can make the pressure roller 29 roll and apply force. It works in conjunction with conveyor roller 25 to convey the fabric and improve work efficiency.

[0038] In this embodiment, a duct 30 is fixedly connected to the middle of the inner side of the housing 1, and an electric heating tube 31 is fixedly connected to the bottom of the inner side of the duct 30.

[0039] In practical use, the electric heating tube 31 heats the air after being powered on. Under the action of the air duct 30, the dry hot air is blown downward, thereby drying the dyed fabric and improving the efficiency of fabric dyeing.

[0040] In this embodiment, a diffuser 32 is fixedly connected to one end of the duct 30, and a fan 33 is fixedly connected to the outer surface of the housing 1 on the side near the duct 30.

[0041] In practical use, by setting up the diffuser 32 and the fan 33, with the fan 33 located at the top of the air duct 30 and the opening of the diffuser 32 gradually expanding from top to bottom, the range of airflow generated by the fan 33 can be expanded, thereby increasing the drying range, enhancing drying efficiency, and improving practicality.

[0042] Working Principle: In use, the color matching instrument 11 selects the dye color to be prepared and controls the flow valve 6 at the bottom of the corresponding dye cylinder 3 to open, allowing the dye inside the dye cylinder 3 to be transported to the mixing cylinder 7 through the first discharge pipe 5. The flow valve 6 senses the amount of dye flowing through, making the addition of dye during color matching more precise. The motor 8 drives the rotating rod 9 to rotate, causing the stirring blade 10 to mix different single-color dyes and combine them into a pre-dyed color. The pressure roller 29 and the conveying roller 25 work together to transport the fabric. The solenoid valve 15 controls the opening of the second discharge pipe 14, and the connecting pipe 16 transports the color-matched dye to the fixed pipe 1. Inside the mixing drum 7, the fabric is dyed by the inkjet head 18. The color measuring camera 13 can photograph and test the dye after color matching to ensure the accuracy of the color. The electric heating tube 31, after being powered on, heats the air. Under the action of the air duct 30 and the fan 33, the dyed fabric is dried. When it is necessary to change the color for dyeing, the dye inside the mixing drum 7 is emptied. The water inlet pipe 19 is opened by the control valve 20 to deliver external water into the mixing drum 7. The scraper 22 scrapes and cleans the inner wall of the mixing drum 7 under the action of the rotating rod 9, so that the mixing drum 7 is cleaned more thoroughly. Then the dye is rematched.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
