Description
Technical Field
[0001] The present invention relates to the technical field of leather clothing printing, and specifically provides a printing method and a printing device for leather clothing. Background Art
[0002] Printing on leather clothing can add various colors, patterns and textures to the leather clothing, break the monotony of solid-color leather clothing, and make it more visually appealing. Exquisite printed patterns can show different styles, such as fashion, retro, ethnic style, etc., meet the diverse aesthetic needs of consumers, and make the leather clothing a unique fashion item.
[0003] During the printing process, if the leather clothing moves or shakes, it will cause the position of the printed pattern to deviate, and the lines and shapes of the pattern will also be deformed, unable to meet the design accuracy requirements. Especially for some fine patterns, such as tiny characters, complex patterns, etc., even a slight displacement may make the pattern blurred or incomplete. Usually, the leather clothing is directly placed on the table, and only friction is used to keep the leather clothing stationary, but the leather clothing may slide, resulting in printing misalignment, misprinting or even damage.

[0011] Preferably, the cooling component includes a frame. The upper surface of the frame is fixedly connected to the lower surface of the mounting rack. A fan is arranged inside the frame.
[0012] Preferably, a printing method for a leather clothing printing device includes the following steps: S1. Preparation stage: Use professional graphic design software to design a pattern, and then import the design drawing into 1103. At the same time, clean the leather clothing to be printed. S2. Test printing: Before formal printing, first perform test printing on the corners, inconspicuous parts of the leather clothing or on a separate test-print leather clothing. Observe the printing effect, whether the color, clarity and depth meet the requirements before proceeding with printing. S3. Fix the leather clothing: Place the leather clothing on the upper surface of the workbench. Start the first motor and push the first slider to slide through the positive and negative lead screw. The first slider makes the lifting rod and the rubber clamping piece press downwards through the first connecting rod to fix the edge of the leather clothing. S4. While fixing the leather clothing, the positive and negative lead screw pushes the second connecting rod to rotate through the second slider. The second connecting rod pushes the protective plate to rise, and the protective plate surrounds the workbench from three sides. S5. Start printing the leather clothing through the laser. The second slide rail makes the first slide rail move back and forth, and the first slide rail makes the second slide rail move left and right. S6. Start the electric push rod to drive the lifting of the mounting frame, move the mounting frame closer to the leather garment, then start the second motor to drive the rotation of the two groups of bevel gears I through the transmission shaft. The bevel gear I drives the reciprocating lead screw to rotate through the bevel gear II. The cleaning brush slides on the surface of the leather garment, and the cooling component slides reciprocally for cooling. First, cool and then clean.
[0013] Preferably, in S5, the laser frequency is 5 - 50 kHz. 20 - 50 kHz is used for delicate lines; 5 - 10 kHz is used for filling or deep engraving. Scan multiple times to deepen the color or depth, but not more than 3 times. The speed is 500 - 3000 mm / s, and the depth of the printed color deepens as the speed decreases.
[0014] Preferably, in step S6, When using air cooling, blow air downward through the fan, and the frame guides the cold air to blow towards the leather garment; When using water cooling, release water mist through the atomizer, and the water mist falls downward to the surface of the leather garment through the water outlet.
[0015] Working principle: When using this device, place the clean leather garment on the workbench. First, start the first motor to drive the rotation of the forward and reverse lead screw at the output end. The forward and reverse lead screw pushes the first slider to slide. The first slider drives the lifting rod to slide through the first connecting rod. The lifting rod lifts and lowers inside the limit frame. When the lifting rod descends, it drives the rubber clamping piece to descend to fix the leather garment.
[0016] When the rubber clamping piece descends, the forward and reverse lead screw simultaneously pushes the second slider to slide. The second slider drives the second connecting rod to rotate. The second connecting rod can push the protective plate to lift and lower. When the protective plate rises, it can block the workbench, thus playing a protective role.
[0017] Through laser irradiation by the laser, the first slide rail and the second slide rail can drive the laser to slide, and a larger pattern can be generated.
[0018] After printing, first perform cooling. You can choose to install the frame and start the fan to blow air for air cooling. Then, start the second motor to drive the rotation of the transmission shaft at the output end. The transmission shaft drives the bevel gear I to rotate through the bevel gear I. The bevel gear II drives the reciprocating lead screw to rotate, which can make the sliding frame slide reciprocally. The sliding frame drives the cooling component to slide, and continuous heat dissipation can be achieved. Similarly, install the atomizer, and the water outlet releases water mist, and the water mist overflows from the water outlet.
[0019] After cooling, the electric push rod can be started to drive the mounting frame at the output end to descend, making the cleaning brush close to the leather garment. When the sliding frame slides, the leather garment can be cleaned.
[0020] The present invention provides a printing method and a printing device for leather garments. It has the following beneficial effects: 1. The present invention drives the forward and reverse lead screw at the output end by starting the first motor. The first slider drives the first connecting rod to rotate, and the lifting rod drives the rubber clamping piece to slide, so that the leather coat can be fixed on the workbench, avoiding problems such as printing offset and dislocation, thereby improving the accuracy and consistency of printing, and ensuring the integrity and beauty of the printed pattern.
[0021] 2. While fixing the leather coat, the present invention drives the second slider to slide by the forward and reverse lead screw. The second slider drives the protective plate to lift through the second connecting rod. When the rubber clamping piece descends, the protective plate ascends. Thus, after the leather coat is fixed, the protective plate provides protection, which can not only prevent personnel from being injured, but also avoid interference during the printing of the leather coat.
[0022] 3. Through the cooperation among the second motor, the transmission shaft, the first bevel gear, the second bevel gear, the reciprocating lead screw, the sliding frame, the electric push rod, the mounting frame, the sliding rod, the cleaning brush, the cooling component, the atomizer, the water outlet, the frame and the fan, the present invention can perform further processing after printing, cool and clean the leather coat, which can ensure the quality of the printed product, and integrating the cleaning and cooling on the mounting frame can reduce costs.

[0030] Please refer to the attached Figure 6 -attachment Figure 7 , the cooling component 27 includes an atomizer 2701. The upper surface of the atomizer 2701 is fixedly connected to the lower surface of the mounting frame 24. An outlet 2702 is arranged inside the atomizer 2701; Specifically, the atomizer 2701 mixes micro - quantified liquid into the air flow to form a mist - like gas - liquid two - phase fluid. By spraying to generate a jet flow, a flow - guiding plate is arranged at the outlet 2702, which can make the spray directly fall on the surface of the leather clothing downward, and cool the leather clothing through the water mist.
[0031] Please refer to the attached Figure 6 and Figure 8 , the cooling component 27 includes a frame 2703. The upper surface of the frame 2703 is fixedly connected to the lower surface of the mounting frame 24. A fan 2704 is arranged inside the frame 2703; Specifically, the frame 2703 fixes the fan 2704.

[0032] Please refer to the attached Figure 9 , a printing method of a printing device for leather clothing includes the following steps: S1. Preparation stage: Use professional graphic design software to design a pattern, and then import the design drawing into the laser 1103. At the same time, clean the leather clothing to be printed; S2. Test printing: Before formal printing, first conduct test printing at the corners, inconspicuous parts of the leather clothing or on a separate test - printed leather clothing. Observe the printing effect, whether the color, clarity and depth meet the requirements before proceeding with printing; S3. Fix the leather coat. Place the leather coat on the upper surface of the workbench 2. Start the first motor 4 to drive the first slider 6 to slide through the positive and negative lead screw 5. The first slider 6 presses down the lifting rod 8 and the rubber clamping piece 10 through the first connecting rod 7 to fix the edge of the leather coat on the workbench 2. S4. While fixing the leather coat, the positive and negative lead screw 5 drives the second connecting rod 13 to rotate through the second slider 12, and the second connecting rod 13 pushes the protective plate 14 to rise, and the protective plate 14 surrounds the workbench 2 from three sides. S5. Start printing the leather coat through the laser 1103. The second slide rail 1102 moves the first slide rail 1101 back and forth, and the first slide rail 1101 moves the second slide rail 1102 left and right. S6. Start the electric push rod 23 to drive the mounting bracket 24 to lift and lower, so that the mounting bracket 24 approaches the leather coat. Then start the second motor 17 to drive the two groups of first bevel gears 19 to rotate through the transmission shaft 18. The first bevel gears 19 drive the reciprocating lead screw 21 to rotate through the second bevel gears 20. The cleaning brush 26 slides on the surface of the leather coat, and the cooling component 27 slides back and forth for cooling. First cool and then clean. Specifically, graphic design software, such as Adobe Photoshop, Illustrator, etc., draws the pattern to be printed according to requirements or design ideas. When designing, attention should be paid to parameters such as the resolution and color mode of the pattern to ensure that the final printing effect is clear and the color is accurate. After the design drawing is imported into the laser 1103, it cooperates with the first slide rail 1101 and the second slide rail 1102 to jointly determine the moving route of the laser 1103. After the trial printing is completed, fix the edge of the leather coat with the rubber clamping piece 10. After the printing is completed, it is necessary to check again to observe the printing effect.
[0033] Please refer to the appendix Figure 9 , in S5, the frequency of the laser 1103 is 5 - 50 kHz, 20 - 50 kHz is used for delicate lines; 5 - 10 kHz is used for filling or deep engraving. Scan multiple times to deepen the color or depth, but not more than 3 times, and the speed is 500 - 3000 mm / s. The depth of the printing color increases as the speed decreases. Specifically, thicker leather may require higher energy and appropriate frequency to penetrate and engrave, while thinner leather requires more delicate frequency control to avoid over - processing. Multiple scans can reflect the layering, but too many scans will cause damage to the leather coat.
[0034] Please refer to the appendix Figure 9 , in step S6, When using air cooling, blow air downward through the fan 2704, and the frame 2703 guides the cold air to blow towards the leather coat. When using water cooling, release water mist through the atomizer 2701, and the water mist falls downward to the surface of the leather coat through the water outlet 2702. Specifically, when high-precision and delicate printing operations are required, using the atomizer 2701 for fog cooling is an ideal choice; in some places with strict requirements for environmental humidity, using the fan 2704 for air cooling is a better choice.
