Description

Technical Field

[0001] The invention relates to the technical field of fabric dyeing equipment, in particular to a digital inkjet dyeing machine used for pure color dyeing of fabrics. Background Art

[0002] As people's quality of life continues to improve and as the level of modern technology continues to improve, people have an increasingly higher pursuit of the color of fabrics. For the solid color dyeing of different types of fabrics, traditional dyeing techniques can be used, or digital printers can be used to print single colors.

[0003] The traditional dyeing process of fabrics can be divided into two types according to the different ways of contact between dyes and fabrics: immersion dyeing and pad dyeing. Immersion dyeing is a dyeing method in which the dyed fabric is immersed in the dye solution, and the dye is evenly dyed on the textile through the circulation of the dye solution and the relative movement of the dyed object. During immersion dyeing, the dye and the dye can be circulated at the same time or in a single cycle; pad dyeing is to immerse the flat fabric in the dye solution for a short time, and then press it with a roller to squeeze the dye solution into the fiber and the gap of the fabric structure, and remove the excess dye solution to make the dye evenly distributed on the fabric. The fabric after pad dyeing is treated by steaming or baking to complete the diffusion and fixation of the dye on the fiber. However, the disadvantages of the traditional dyeing process are: large minimum order quantity, large color difference, large water consumption, large amount of steam, etc., large difference in color matching and dyeing matching, and more dependence on the level of the master. The traditional dyeing process is not environmentally friendly, high cost, and low efficiency; its advantages are: wide color gamut, good dyeing uniformity, and high depth and hue.

[0004] At present, all the solid color printing achieved by digital printing on the market are based on the printing mode of digital textile printers. Multiple colors are positioned and dotted to achieve solid color visual effects. The biggest problem with this printing method is that the printed solid color fabrics have a visual sense of dot-like granularity, resulting in rough dots, insufficient color hue and saturation, insufficient depth and ink volume, and unsatisfactory color consistency. It has the disadvantages of not being able to achieve industrial, large-area, high-speed, and long-term solid color block printing. In addition, digital textile printers have high requirements for color management during printing, and the color reproduction degree cannot meet the requirements of solid color printing, and the color gamut that can be printed is limited.

[0005] In view of this, how to overcome the shortcomings of traditional dyeing process, such as being environmentally unfriendly, high cost, and low efficiency when performing solid color dyeing, as well as the shortcomings of digital solid color printing having a dot-like graininess and low color accuracy, has become a topic to be studied and solved by the present invention. Summary of the invention

[0006] The purpose of the present invention is to provide a digital inkjet dyeing machine, which overcomes the shortcomings of traditional dyeing processes such as being environmentally unfriendly, high cost, and low efficiency when performing pure color dyeing, and digital pure color printing having a dot-like granularity and low color accuracy. The digital inkjet dyeing machine of the present invention has the advantages of both traditional dyeing processes and digital printing, such as being clean, fast, and having complete color matching between printed samples and large-scale production, a wide color gamut, very good uniformity, and the same depth and hue as traditional dyeing.

[0007] To achieve the above object, the method and technical solution adopted by the present invention is: a digital inkjet dyeing machine for performing pure color digital dyeing on fabrics, comprising a fabric unwinding and feeding device, an inkjet device, a drying device and a winding device sequentially arranged along the fabric feeding direction;

[0008] The unwinding and feeding device is used to transport the fabric to be dyed to the working station of the inkjet device;

[0009] An inkjet device, used for printing the configured ink onto the fabric;

[0010] A drying device, used to dry the dyed fabrics;

[0011] A winding device is used to wind up the dried fabric;

[0012] The innovation lies in that the inkjet device comprises an organism, a controller, an ink tank, a cleaning liquid tank, a waste liquid barrel and an inkjet module;

[0013] At least two groups of inkjet modules, at least one ink tank, at least one cleaning liquid tank and at least one waste liquid barrel are arranged on the machine body, wherein the ink tank is a container for holding ink, the cleaning liquid tank is a container for holding cleaning liquid, and the waste liquid barrel is a container for collecting waste liquid;

[0014] The machine body is provided with a working area and a cleaning area; the inkjet module is installed on the machine body and can move between the working area and the cleaning area;

[0015] The inkjet module includes a nozzle, a positioning frame, and a supporting and moving mechanism; a plurality of nozzles arranged in parallel constitute a nozzle group, each inkjet module includes at least one nozzle group, a plurality of nozzles are connected by an ink pipeline, the ink pipeline is connected to an ink tank and a cleaning liquid tank through a pipeline, an inkjet valve is arranged on the pipeline between the ink pipeline and the ink tank, and a cleaning valve is arranged on the pipeline between the ink pipeline and the cleaning liquid tank; the nozzle is mounted on the positioning frame, the positioning frame is mounted on the supporting and moving mechanism, and the supporting and moving mechanism includes a lifting unit for lifting the positioning frame up and down in the working area and a translation unit for lateral translation of the positioning frame in the cleaning area;

[0016] A cleaning support guide plate and a guide plate are arranged below the cleaning area. A guide hole for waste liquid to flow out is opened in the guide plate, and the waste liquid enters the waste liquid barrel through the guide hole.

[0017] The relevant contents of the present invention are explained as follows:

[0018] The workflow of the above technical solution is: carry out fixed single-channel inkjet dyeing production, put the pre-treated fabric to be dyed on the machine; load the color-matched ink into the ink system; start the machine, the unwinding and feeding device transports the fabric to be dyed to the station of the inkjet device, the inkjet device directly sprays the dyeing, and prints the configured ink on the fabric; the printed fabric is sent to the drying device via the guide belt device; the dried fabric is reeled by the reeling device. The newly added color adds nodes, which greatly improves the accuracy of the formula of the color added later. Moreover, during the dyeing work, only one group of inkjet modules is working. When the first group of inkjet modules is working, the other inkjet modules are cleaned and changed ink under the control of the microcomputer. First, the ink in the other inkjet modules is emptied, and then the valve of the cleaning liquid pool leading to the other inkjet modules is opened for cleaning. After the cleaning is completed, the valve of the ink pool with the configured ink is opened, and the ink enters the other inkjet modules to prepare for the next color printing.

[0019] In the above technical solution, the inkjet device has two groups of inkjet modules, the nozzle groups in the two groups of inkjet modules are respectively connected to an ink tank, and the nozzle groups in the two groups of inkjet modules are commonly connected to a cleaning liquid tank and a waste liquid barrel; however, the present invention is not limited to this, and one ink module can use a cleaning liquid tank and a waste liquid barrel alone.

[0020] In the above technical solution, the supporting and moving mechanism is mainly composed of a motor driver with lifting and translation functions, that is, the lifting unit and the translation unit are both motor drivers. The motor driver has the functions of lifting and moving. When the nozzle group needs to work, the motor driver moves the nozzle group to the inkjet position, and lowers the nozzle group to a certain height to enter the working area to perform inkjet work; when the nozzle group has completed inkjet and needs to be cleaned and the ink is changed (the color is changed), the motor driver first raises the nozzle group to a certain height, and then moves the nozzle group horizontally to the cleaning area, that is, moves it to the top of the cleaning support guide plate and the guide plate, to perform cleaning and ink change work.

[0021] In the above technical solution, a trapezoidal guide groove is provided on the upper surface of the guide plate, and the guide hole is located at the bottom of the guide groove. The trapezoidal guide groove is a trapezoidal groove design, which can allow the cleaning ink or waste ink to easily flow out of the guide groove and flow into the waste liquid barrel through the guide hole, thereby speeding up the cleaning efficiency and improving the convenience of cleaning and ink changing (color changing) work.

[0022] .In the above technical solution, the machine body is divided into two parts, each of which is independently provided with an inkjet module, an ink tank, a working area, and a cleaning area therein, and the two machines share a cleaning liquid tank and a waste liquid barrel; the purpose of separately providing an inkjet module, an ink tank, a working area, and a cleaning area in each machine body is to facilitate the completion of inkjet of the nozzle group, and when cleaning and ink changing (color changing) are required, the respective inkjet and cleaning work will not be disturbed, and the cleaning and ink changing work can be performed independently, so that the cleaning and ink changing (color changing) work can be more thorough and avoid staining.

[0023] In the above technical solution, universal wheels are provided at the bottom of the machine body to facilitate the movement of the machine body for subsequent repair, maintenance or other operations.

[0024] In the above technical solution, the nozzle adopts a nozzle with an ink output of 12pl to 80pl. The ink used is compatible with the ink used by the digital printing machine, and can also use the special ink for the digital dyeing machine. The ink has a large particle size range, less damage to the chromophore group, and the coloring effect is greatly improved than the coloring effect of printing pure colors by the printing machine.

[0025] In the above technical solution, the nozzles in the inkjet module are connected by pipelines in a single-channel series manner, that is, the ink pipelines between the multiple nozzles are connected in series, and inkjet printing is performed on the cloth surface with a single-channel, fixed row of nozzles. This will not produce the dot-like granularity that is the most troublesome thing for conventional digital printing machines.

[0026] In the above technical solution, the digital inkjet dyeing machine is provided with a belt guide device, which is arranged between the inkjet device and the drying device and is used to transport the fabric dyed by the inkjet device to the drying device.

[0027] In the present invention, unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In the present invention, the orientation or position relationship indicated by terms such as "center", "upper", "lower", "circumferential", "bottom", "inside", and "outside" are based on the orientation or position assembly relationship shown in the drawings, and are only for the convenience of describing the present application 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 on the present application.

[0029] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] Due to the application of the above scheme, the present invention has the following advantages and effects compared with the prior art:

[0031] 1. In the above scheme of the present invention, a fixed, single-channel nozzle is used to evenly dot a single color of ink with good color matching on the textile to complete digital solid color printing. This will not produce the dot-like granularity that is the most troublesome for conventional digital printing machines. Since the printing does not have the dot-like granularity, a nozzle with a large ink output can be used. The ink used is compatible with the ink used by the digital printing machine. At the same time, the special ink for the digital dyeing machine can also be used. The ink has a large particle size range, the chromophore group is less damaged, and the coloring effect is greatly improved than the coloring effect of printing solid colors by the printing machine.

[0032] 2. In the above scheme of the present invention, at least two groups of inkjet modules are adopted, and the two groups of inkjet modules can be used interchangeably. The inkjet modules of one group enter the inkjet position of the working area under the drive of the lifting unit of the supporting movable mechanism, and lower the nozzle group to a certain height to perform inkjet work, while the other group of inkjet modules can be cleaned or ink-changed in the cleaning area; when the inkjet module in the working area completes inkjet and needs to be cleaned or ink-changed, the lifting unit of the supporting movable mechanism drives the inkjet module to rise to a certain height, and the translation unit drives the inkjet module to move horizontally to the cleaning area, that is, to the top of the cleaning support guide plate and the guide plate, for cleaning and ink-changing work, while the other group enters the working area to perform inkjet printing work, so its working efficiency is high, and the nozzle is cleaned in time to prevent the nozzle from being blocked and to avoid residual ink affecting the inkjet quality.

[0033] 3. In the above scheme of the present invention, the nozzles are installed in a row on the positioning frame. When spraying ink, the lifting unit of the supporting moving mechanism drives the inkjet module to be lowered to the inkjet position of the working area before the inkjet operation is carried out. The inkjet operation has high inkjet accuracy and good inkjet effect.

[0034] 4. In the above scheme of the present invention, the inkjet module can print dispersed, active, coating, acidic and other inks, and the printable fabrics include almost all types of fabrics such as polyester, cotton, silk, wool, blended fabrics, etc., with a wide range of applications.
