Description

Technical Field

[0001] The present invention relates to the technical field of batik equipment, and in particular to an automatic wax - dotting device for batik and a batik method. Background Art

[0002] As a characteristic craft passed down for thousands of years, the core of batik is to form an anti - dyeing layer on the blank fabric through molten beeswax. After dyeing is completed, the fabric is boiled and washed with boiling water to remove the wax layer, revealing white patterns to achieve pattern blanking. When the batik process performs anti - dyeing treatment, it needs to execute the wax - dotting process, and its technological process is divided into four stages: fabric pretreatment, wax melting, manual wax application, and cooling and shaping.

[0003] The traditional method in the prior art uses the manual wax - dotting method with a copper knife. The specific operation is as follows: After heating beeswax to 65 - 80°C and melting it, a craftsman holds a copper wax knife (the width of the knife edge is 0.5 - 3 mm) and draws patterns on the surface of the stretched fabric. Through the capillary action of the wax knife, the wax liquid penetrates to form an anti - dyeing layer. However, traditional manual operation relies on applying wax with a copper wax knife, and there are significant industrialization bottlenecks: Manual wax application requires precise control of the wax liquid temperature and the application pressure. Since the heating temperature of the open - type wax pot fluctuates by ±8°C, the viscosity of the wax liquid changes by more than 25%, the thickness of the wax layer is uneven, and there is a color difference at the boundary after dyeing. At the same time, there is a lack of a reusable template system. When making repeated patterns, the positioning error accumulates up to 1.2 - 2.5 mm, resulting in a qualified rate of less than 78% for products in the same batch. Moreover, the daily output of skilled craftsmen is only 3 - 5 square meters, which cannot meet the production capacity requirement of hundreds of meters per day in industrial production. Also, during the manual wax - application process, due to the uneven temperature field distribution of the wax knife and the fluctuation of the application pressure, there will be regional differences in the penetration depth of the wax liquid. Experimental data shows that on a cotton fabric with a width of 1.2 m, the average thickness of the wax layer at the cloth edge position (within 10 cm from the edge) is 0.28 ± 0.05 mm, while the thickness in the middle area reaches 0.35 ± 0.08 mm (detection standard GB / T 13773). This difference causes anti - dyeing failure in the indigo dyeing process, increasing the blurring degree of the pattern outline at the cloth edge (calculated by the CIE2000 color - difference formula) by ΔE>2.5 compared with the middle area, directly resulting in the defective rate rising to 18% - 22% (industrial production requirement <5%), and the production cost per batch increasing by more than 37%. In addition, the manual operation speed is limited (skilled craftsmen can only complete 0.3 m2 / h), which cannot meet the production capacity requirement of 500 m per day in modern textile industry.

[0004] There are also products in the prior art that use industrial equipment for batik. For example, Chinese Patent CN119553454A published on 2025 - 03 - 04, etc. These technologies use a spray head to move on the dyed fabric for batik. However, in these patents, a printing plate needs to be used to cover the blank fabric, but the cost of the printing plate mold is relatively high, and the formed batik pattern is affected by the pre - fabricated hollowing on the printing plate, which is inconvenient for different batik requirements of patterns.

[0005] Therefore, in the prior art, there is a relative lack of means to directly paint wax liquid automatically, and the process of making batik cloth with the same pattern or multiple sets of patterns is relatively complex and the processing time is too long. Summary of the Invention

[0038] Embodiment 1

[0039] As Figures 1-8As shown in the figure, the present invention provides an automatic wax - dotting device for batik, which includes a mounting frame 1, a traveling frame 2, a cloth - placing frame 3, and a controller 7. The traveling frame 2 and the cloth - placing frame 3 are respectively installed on the mounting frame 1. A traveling mechanism 5 is installed on the traveling frame 2, and a wax - dotting nozzle 6 is connected to the traveling mechanism 5. The traveling mechanism 5 is in signal connection (such as electrical signal connection) with the controller 7. The controller 7 stores the pattern - drawing information of the cloth to be dyed 4. The cloth - placing frame 3 is fixed with the cloth to be dyed 4. The wax - dotting nozzle 6 is located above the cloth to be dyed 4.

[0040] Specifically, the mounting frame 1 is used to install the traveling frame 2, the cloth - placing frame 3, and the controller 7. The traveling frame 2 is a profile frame installed on the top of the mounting frame 1. The traveling mechanism 5 can adopt a three - axis slide rail mechanism to realize the movement control of the wax - dotting nozzle 6 in the X, Y, and Z directions. By moving the wax - dotting nozzle 6 in the Z direction, the height distance between the wax - dotting nozzle 6 and the cloth to be dyed 4 below can be adjusted. By moving the wax - dotting nozzle 6 in the XY direction, accurate automatic pattern drawing can be carried out on the cloth to be dyed 4 below. The user designs and arranges through special software on a computer, converting the pattern or text to be drawn into numerical control codes. These codes usually exist in the form of G - codes, containing information such as the movement paths of the engraving machine in the X - axis, Y - axis, and Z - axis directions and the opening and closing instructions of the laser. Then, these numerical control codes are transmitted to the controller 7 through a serial communication interface (such as USB) or a wireless communication module (such as WiFi, Bluetooth). The controller 7 can receive and parse these numerical control codes, convert them into specific control signals, and finally send them to each motion module through electrical signals.

[0041] The cloth - placing frame 3 is used to place, fix, and carry the cloth to be dyed 4. The wax - dotting nozzle 6 is a device for storing, melting, and spraying wax. After melting the wax, it supplies the nozzle 64 with wax liquid to be sprayed onto the cloth to be dyed 4 below, realizing pattern drawing.

[0042] Since the present invention directly uses the controller 7 to control the traveling mechanism 5 to move the wax - dotting nozzle 6 on the cloth to be dyed 4 to draw the corresponding pattern. Therefore, during the batik process, the present invention does not need to use a flower board as a template part and is not affected by the pre - fabricated hollow patterns on the flower board, and can quickly and conveniently realize the automatic batik painting of the same pattern or multiple sets of patterns on the fabric, greatly improving the batik efficiency.

[0043] Embodiment 2

[0044] The wax - dotting nozzle 6 includes an extruder 61, a wax storage box 62, a heater 63, and a nozzle 64. Wax is stored in the wax storage box 62. The wax storage box 62, the heater 63, and the nozzle 64 are sequentially communicated with the inside of the extruder 61 from top to bottom. The extruder 61 includes an extrusion power device 611 and an extrusion tube 612. The extrusion power device 611 is connected to the top pipe orifice of the extrusion tube 612. The wax storage box 62, the heater 63, and the nozzle 64 are communicated into the extrusion tube 612.

[0045] Specifically, the extrusion power device 611 can adopt a (stepper) extrusion motor or pneumatic control. By converting the rotation of the motor to drive the internal extrusion rod to perform telescopic motion (such as a motor lead screw structure), molten wax liquid is extruded. The heater 63 includes a main body, a heating rod, and a temperature sensor. The input and output ends of the heater 63 are respectively connected to the micro extruder 61 and the nozzle 64. A heating rod and a temperature sensor are arranged in the inner cavity of the heater 63 to heat the passing wax. The main body of the heater 63 is a square block, and the heating rod and the temperature sensor are installed inside the main body block. Heating devices such as heating coils and heating rings can also be used for replacement.

[0046] The extrusion motor, the wax powder storage box, the micro extruder 61, and the heater 63 are all installed above the nozzle 64. In the extrusion tube 612 of the extrusion motor 561, a fluid passage is formed. The wax storage box 62 is in an open shape and is connected to the inside of the extrusion tube 612. The wax storage box 62 contains wax powder for easy flow and melting into the extrusion tube 612. After the wax powder enters the extrusion tube 612, it flows downward to the position of the heater 63, where it is melted into wax liquid by the heater 63 and is extruded from the nozzle 64 through the extruder 61.

The cloth placing frame 3 is suspended in the middle of the mounting frame 1 to facilitate placing and fixing the cloth to be dyed 4.

[0050] In addition, the cloth placing rack 3 is composed of at least two slide rails 31 and at least two cloth clamping plates 32.
