Abstract

The dyeing machine comprises a controller, a liquid storage cylinder used for storing dye and a plurality of printing and dyeing units connected with the liquid storage cylinder, each printing and dyeing unit comprises a spray head used for spraying the dye and a liquid supply pipeline used for communicating the liquid storage cylinder with the spray head, and the spray heads of the printing and dyeing units are arranged side by side. The printing and dyeing unit further comprises a power pump arranged on the liquid supply pipeline, and the power pump is electrically connected with the controller and used for controlling the liquid outlet amount of the spray head. The liquid outlet amount of the spray head of each printing and dyeing unit is controlled through the corresponding power pump, and in the printing and dyeing process, if a worker finds that the dye liquid amount of some positions of cloth is too large or too small, the worker can find the spray head corresponding to the position and adjust the power pump through the controller so as to change the liquid outlet amount of the corresponding spray head. Therefore, the amount of dye liquor sprayed on the cloth by each spray head in unit time is the same, and each position of the cloth is uniformly printed and dyed.

Description

Technical Field

[0001] This utility model belongs to the field of printing and dyeing equipment, and specifically relates to a printing and dyeing machine that produces uniform printing and dyeing. Background Technology

[0002] Commercially available printing and dyeing machines typically have multiple nozzles arranged side-by-side. As the fabric passes under these nozzles, they simultaneously spray dye to color different areas of the fabric. However, during the printing and dyeing process, manufacturing errors in the nozzles can lead to variations in the nozzle orifice size. This results in different amounts of dye being sprayed from each nozzle at the same time. Furthermore, after prolonged operation, particulate matter in the dye can cause varying degrees of wear on each nozzle, further compromising orifice size and causing inconsistent dye output. All of these factors contribute to uneven dyeing and poor printing and dyeing results. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a printing and dyeing machine with uniform printing and dyeing, so as to solve the problem of uneven printing and dyeing caused by manufacturing process errors of the nozzles and wear differences of multiple nozzles after long-term use of the printing and dyeing machine.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a dyeing machine for uniform printing and dyeing, comprising a controller, a storage tank for storing dye, and multiple printing and dyeing units connected to the storage tank. Each printing and dyeing unit includes a nozzle for spraying dye and a supply pipeline connecting the storage tank and the nozzle. The nozzles of the multiple printing and dyeing units are arranged side-by-side. Each printing and dyeing unit also includes a power pump located on the supply pipeline. The power pump is electrically connected to the controller to control the output volume of the nozzle. This technical solution has the following technical effects:

[0005] This invention incorporates a power pump within the dyeing unit, with each pump corresponding to a specific nozzle. The output of each nozzle in the dyeing unit is controlled by its corresponding power pump. During the dyeing process, if workers find that certain areas of the fabric have too much or too little dye, they can locate the nozzle corresponding to that area and adjust the power pump via the controller to change the output of that nozzle. This ensures that the output of each nozzle in the dyeing unit is controlled to be the same, resulting in uniform dyeing across all areas of the fabric. Even if there are manufacturing errors between nozzles, or if particulate matter in the dye causes varying degrees of wear on the nozzles after prolonged use, it will not affect the uniform application of dye. No nozzle replacement is required, thus guaranteeing uniform dyeing and reducing dyeing costs.

[0006] In the aforementioned uniform dyeing machine, the dyeing unit further includes a waste liquid pipeline and a waste liquid valve for opening and closing the waste liquid pipeline. The waste liquid pipeline is connected to the nozzle to discharge waste liquid from the nozzle. When the dyeing machine is performing dyeing operations, the waste liquid valve is closed to prevent dye from leaking from the waste liquid pipeline. When the nozzle is blocked or when cleaning fluid such as water is injected into the storage tank to clean the nozzle, the waste liquid valve is opened, allowing the accumulated dye or cleaning fluid and other waste liquid at the nozzle to flow out quickly through the waste liquid pipeline from the nozzle, preventing excessive pressure at the nozzle from causing damage and improving cleaning efficiency.

[0007] In the aforementioned dyeing machine for uniform printing and dyeing, the machine also includes a waste liquid tank, which is connected to the outlet end of the waste liquid pipeline. This ensures that all waste liquid flowing out of the waste liquid pipeline is collected in the waste liquid tank, preventing pollution.

[0008] In the aforementioned uniform dyeing and printing machine, the machine also includes a liquid collection pipeline. The waste liquid pipelines of multiple dyeing and printing units are connected to the same waste liquid cylinder through the liquid collection pipeline to reduce the number of waste liquid cylinders, simplify the internal structure of the dyeing and printing machine, and reduce the difficulty of production and processing. Alternatively, multiple waste liquid cylinders are provided, and the waste liquid pipelines of multiple dyeing and printing units are connected to multiple waste liquid cylinders one by one to reduce the assembly difficulty.

[0009] In the aforementioned uniform printing and dyeing machine, the printing and dyeing unit also includes a pressure detection device electrically connected to the controller. This pressure detection device is located on the waste liquid pipeline upstream of the waste liquid valve to detect the pressure at the nozzles and adjust the liquid output of the nozzles via the controller and power pump. The pressure detection device can detect the pressure at the nozzles and transmit it to the controller. The controller can adjust the power pump based on the detected pressure value, thereby adjusting the liquid output of the nozzles to maintain stable nozzle pressure in each printing and dyeing unit. If the nozzle orifice becomes clogged, causing excessive pressure at the nozzle, the pressure detection device can quickly feed back the detected pressure to the controller, prompting the operator to clean or replace the nozzles to ensure stable spraying of the fabric.

[0010] In the aforementioned uniform dyeing machine, the dyeing unit further includes a flow detection device electrically connected to the controller. The flow detection device is located on the liquid supply pipeline and adjusts the output flow of the nozzles via the controller and the power pump. By installing the flow detection device on the liquid supply pipeline, the flow detection device can detect the flow rate of the nozzles during the process of the power pump drawing dye from the storage tank to the nozzles, and feed this information back to the controller. The controller then controls the power pump to maintain the nozzle flow rate of each dyeing unit at the same value, ensuring that each nozzle sprays the same amount of dye onto the fabric per unit time. This achieves automatic control of the nozzle flow rate, resulting in more uniform dyeing.

[0011] In the aforementioned uniform dyeing machine, the flow detection device is a flow meter. Using a smaller flow meter as the flow detection device significantly reduces the space occupied by the flow detection device. At the same time, it offers high measurement accuracy and good monitoring effect on the flow rate at the nozzle.

[0012] In the aforementioned uniform dyeing machine, the inlet end of the liquid supply pipeline is equipped with a liquid supply valve for opening and closing the liquid supply pipeline, and the liquid supply valve is located upstream of the power pump. When multiple dyeing units share a single distribution pipeline connected to the storage tank, when some dyeing units with open liquid supply valves draw dye from the storage tank via the power pump, other dyeing units with closed power pumps can prevent dye from entering the nozzles through the power pump under the influence of other dyeing units by using their closed liquid supply valves, thereby avoiding leakage from nozzles that do not require spraying.

[0013] In the aforementioned uniform dyeing machine, a filter device for filtering dye is also installed on the liquid supply pipeline. The filter device is used to filter the dye that is about to enter the printhead, preventing large particles in the dye from entering the printhead and causing wear or blockage, thus extending the service life of the printhead.

[0014] In the aforementioned uniform dyeing and printing machine, the machine also includes a liquid distribution pipeline. The liquid supply pipelines of multiple dyeing and printing units are connected to the same liquid storage tank through the liquid distribution pipeline, thereby reducing the number of liquid storage tanks, simplifying the internal structure of the dyeing and printing machine, and reducing the difficulty of production and processing. Alternatively, multiple liquid storage tanks are provided, and the liquid supply pipelines of multiple dyeing and printing units are connected to multiple liquid storage tanks one by one, thereby reducing the difficulty of assembly.

[0024] This utility model proposes a uniform dyeing machine, including a controller, a storage tank for storing dye, and multiple dyeing units connected to the storage tank. Each dyeing unit includes a nozzle for spraying dye and a supply pipeline for connecting the storage tank and the nozzle. The nozzles of the multiple dyeing units are arranged side by side. The dyeing unit also includes a power pump located on the supply pipeline. The power pump is electrically connected to the controller to control the amount of dye output from the nozzle. This invention incorporates a power pump within the dyeing unit, with each pump corresponding to a specific nozzle. The output of each nozzle in the dyeing unit is controlled by its corresponding power pump. During the dyeing process, if workers find that certain areas of the fabric have too much or too little dye, they can locate the nozzle corresponding to that area and adjust the power pump via the controller to change the output of that nozzle. This ensures that the output of each nozzle in the dyeing unit is controlled to be the same, resulting in uniform dyeing across all areas of the fabric. Even if there are manufacturing errors between nozzles, or if particulate matter in the dye causes varying degrees of wear on the nozzles after prolonged use, it will not affect the uniform application of dye. No nozzle replacement is required, thus guaranteeing uniform dyeing and reducing dyeing costs.

[0030] Example 1:

[0031] A printing and dyeing machine that produces even printing, such as Figures 1 to 2 As shown, it includes a controller 100, a liquid storage tank 210, and a dyeing and printing unit 400. Figure 1(The part inside the dashed box) The liquid storage tank 210 is used to store dye. The printing and dyeing unit 400 is provided with multiple units (two or more). Multiple printing and dyeing units 400 are connected to the liquid storage tank 210 so as to provide dye to the printing and dyeing unit 400 through the liquid storage tank 210. Each dyeing and printing unit 400 includes a nozzle 410, a liquid supply line 420, a power pump 440, and a flow detection device 430. The nozzle 410 is used to spray dye onto the fabric. The liquid supply line 420 is connected between the liquid storage tank 210 and the nozzle 410. The nozzles 410 of multiple dyeing and printing units 400 are arranged side by side on the dyeing and printing machine. The power pump 440 is located on the liquid supply line 420 to draw dye from the liquid storage tank 210 through the liquid supply line 420 and spray it out from the nozzle 410. The flow detection device 430 is located upstream of the nozzle 410 and is electrically connected to the controller 100 to detect the flow rate of the nozzle 410. Preferably, the flow detection device 430 is a flow meter. Using a smaller flow meter as the flow detection device 430 greatly reduces the space occupied by the flow detection device 430. At the same time, it has high measurement accuracy and good monitoring effect on the flow rate at the nozzle 410.

[0032] During the dyeing process, manufacturing errors in the printheads can lead to variations in the nozzle size, resulting in different amounts of dye sprayed from each nozzle at the same time. Furthermore, particulate matter in the dye can cause wear on the inner walls of the nozzle nozzles. After prolonged operation, the varying degrees of wear on each nozzle result in inconsistent nozzle sizes, further altering the amount of dye sprayed from each nozzle at the same time. Consequently, the amount of dye sprayed on different parts of the fabric varies, leading to uneven dyeing. This invention incorporates a power pump 440 within the dyeing unit 400, ensuring a one-to-one correspondence between the power pump 440 and the nozzle 410. The output of each nozzle 410 in each dyeing unit 400 is controlled by its corresponding power pump 440. During the dyeing process, if workers find that the amount of dye in certain areas of the fabric is too high or too low, they can locate the nozzle 410 corresponding to that location and adjust the power pump 440 via the controller 100 to change the output of the corresponding nozzle 410. This ensures that the output of each nozzle 410 in each dyeing unit 400 is controlled to the same value, resulting in uniform dyeing across all areas of the fabric. Even if there are manufacturing process errors among the nozzles 410, or if the nozzles 410 experience varying degrees of wear due to particulate matter in the dye after prolonged operation, the uniform dyeing will not be affected. The uniform dyeing of the fabric can be guaranteed without replacing the nozzles 410, thus reducing dyeing costs. By installing a flow detection device 430 on the liquid supply pipeline 420, the flow detection device 430 can detect the flow rate of the nozzle 410 during the process of the power pump 440 drawing dye from the storage tank 210 to the nozzle 410 and feeding it back to the controller 100. The controller 100 then controls the power pump 440 to control the flow rate of the nozzle 410 in each printing and dyeing unit 400 to the same value, thereby achieving automatic control of the nozzle flow rate and making the printing and dyeing more uniform.

[0033] In this embodiment, the dyeing and printing unit 400 also includes a waste liquid pipeline 450 and a waste liquid valve 460. The waste liquid valve 460 is located on the waste liquid pipeline 450 for opening and closing the waste liquid pipeline 450. The inlet end of the waste liquid pipeline 450 is connected to the nozzle 410. When the dyeing and printing machine is performing dyeing and printing work, the waste liquid valve 460 is closed to prevent dye from leaking from the waste liquid pipeline 450. When the nozzle 410 is blocked or when water or other cleaning liquid is injected into the storage tank 210 to clean the nozzle 410, the waste liquid valve 460 is opened, allowing the accumulated dye or cleaning liquid and other waste liquid at the nozzle 410 to flow out quickly from the nozzle 410 through the waste liquid pipeline 450, preventing excessive pressure at the nozzle 410 from causing damage and improving cleaning efficiency.

[0034] To collect the waste liquid, this embodiment also includes a waste liquid tank 220 connected to the outlet end of the waste liquid pipeline 450, so that all the waste liquid flowing out of the waste liquid pipeline 450 is collected in the waste liquid tank 220, avoiding pollution caused by the waste liquid. Preferably, there is one waste liquid tank 220 in this embodiment. The dyeing and printing machine also includes a collection pipeline 320. The waste liquid pipelines 450 of multiple dyeing and printing units 400 are connected to the same waste liquid tank 220 through the collection pipeline 320. That is, the multiple inlet ends of the collection pipeline 320 are respectively connected to the waste liquid pipelines 450 of each dyeing and printing unit 400, and the outlet end of the collection pipeline 320 is connected to the waste liquid tank 220, reducing the number of waste liquid tanks 220, simplifying the internal structure of the dyeing and printing machine, and reducing the difficulty of production and processing. Of course, it is understandable that in another embodiment, the same number of waste liquid cylinders as the dyeing and printing units can be set up, and the waste liquid pipelines are connected to the waste liquid cylinders one by one, so that the waste liquid in the waste liquid pipelines of each dyeing and printing unit is discharged into different waste liquid cylinders respectively.

[0035] The dyeing and printing unit 400 also includes a pressure detection device 470, which is electrically connected to the controller 100. The pressure detection device 470 is located at the inlet end of the waste liquid pipeline 450, upstream of the waste liquid valve 460. When the dyeing and printing machine is operating to dye the fabric, the nozzle 410 is connected to the waste liquid pipeline 450 upstream of the waste liquid valve 460, allowing the pressure detection device 470 to detect the pressure at the nozzle 410 and transmit it to the controller 100. If the nozzle 410 becomes clogged, causing excessive pressure at the nozzle 410, the pressure detection device 470 can quickly feed back the detected pressure to the controller 100, prompting the operator to clean or replace the nozzle 410, ensuring stable spraying of the fabric by the nozzle 410. Preferably, the pressure detection device 470 is a pressure gauge.

[0036] In this embodiment, the dyeing and printing machine further includes a dispensing pipe 310. The supply pipes 420 of multiple dyeing and printing units 400 are connected to the same storage tank 210 via the dispensing pipe 310. Specifically, the inlet end of the dispensing pipe 310 is connected to the storage tank 210, and multiple outlet ends are connected to the supply pipes 420 of each dyeing and printing unit 400. This reduces the number of storage tanks 210, simplifies the internal structure of the dyeing and printing machine, and reduces production difficulty. Of course, it is understood that in other embodiments, multiple storage tanks can be provided, with the number of storage tanks being the same as the number of dyeing and printing units, and the supply pipes of multiple dyeing and printing units connected to the storage tanks one-to-one.

[0037] Because the width of the fabric to be printed varies, when printing the fabric, only the power pumps 440 corresponding to the few nozzles 410 directly opposite the fabric need to be turned on for spraying. The power pumps 440 of the other nozzles 410 do not need to be started. That is, the number of nozzles 410 that need to be turned on varies depending on the width of the fabric to be printed. To enable rapid opening and closing of each nozzle 410, this embodiment provides a supply valve 480 at the inlet end of the supply pipeline 420. The supply valve 480 is located upstream of the power pump 440 and is used to open and close the supply pipeline 420. When multiple dyeing units 400 share a distribution pipeline 310 connected to the storage tank 210, when some dyeing units 400 with open supply valves 480 draw dye from the storage tank 210 through the power pump 440, other dyeing units 400 with closed power pumps can prevent dye from entering the nozzle 410 through the power pump 440 under the influence of other dyeing units 400, thereby avoiding leakage from nozzles 410 that do not require spraying.

[0038] In this embodiment, a filter device 490 is also provided on the liquid supply pipeline 420. The filter device 490 is used to filter the dye. Preferably, the filter device 490 is located at the inlet of the nozzle 410, so that the filter device 490 can filter the impurities that fall from the upstream liquid supply valve 480, power pump 440 and flow detection device 430, so as to avoid the presence of large particles in the dye that is about to enter the nozzle 410, thereby avoiding the wear or blockage of the nozzle 410 caused by the large particles in the dye, and extending the service life of the nozzle 410.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
