Description

Technical Field

[0001] This utility model relates to the field of digital printing machine technology, specifically to a multi-color positioning device for digital printing of fabrics. Background Technology

[0002] In the textile printing and dyeing industry, digital fabric printing technology has gradually become the mainstream printing method due to its advantages such as high precision, high color saturation and the ability to achieve personalized customization. Multi-color positioning printing, as a key link in digital printing, plays a vital role in ensuring the accuracy of printed patterns and the precise matching of colors. However, current multi-color positioning technology and equipment for digital fabric printing still have many shortcomings.

[0003] Traditional fabric printing positioning methods mainly rely on mechanical positioning and manual calibration. Mechanical positioning devices usually use fixed molds or guide rails to determine the position of the fabric. However, this method lacks flexibility and is difficult to adapt to fabrics of different sizes and shapes. For some irregularly shaped or special-sized fabrics, mechanical positioning often cannot provide accurate positioning, resulting in offset or misalignment of the printed pattern, which seriously affects the printing quality. Although manual calibration can make up for the shortcomings of mechanical positioning to some extent, the calibration process is not only time-consuming and labor-intensive, but also easily affected by the experience and skill level of the operator, resulting in unstable positioning accuracy and difficulty in meeting the needs of large-scale production.

[0004] In terms of position adjustment of printing machines, existing technologies are relatively limited. Traditional equipment can usually only make simple horizontal or vertical movements, making it difficult to achieve high-precision fine adjustments. When printing multicolor patterns, different colors need to be precisely aligned. Even a slight positional deviation can lead to color overlap or excessive gaps, affecting the printing effect. Existing adjustment methods cannot meet this high-precision positioning requirement, resulting in frequent problems of inaccurate color alignment during the printing process, which reduces the yield rate of products. To solve the above problems, we propose a multicolor positioning device for digital fabric printing. Utility Model Content

[0015] Compared with the prior art, this utility model provides a multi-color positioning device for digital printing of fabrics, which has the following beneficial effects:

[0016] 1. The digital printing multi-color positioning device for this fabric uses a first motor to drive the first threaded screw to rotate, which, in conjunction with the first slide rod, can precisely control the translation of the moving plate on the base, achieving initial and accurate adjustment of the position of the placement plate. At the same time, a second motor drives the second threaded screw to rotate, causing the placement plate to translate along the direction of the second slide rod on the moving plate for secondary adjustment. This dual adjustment mechanism greatly improves the positioning accuracy of the fabric during the printing process.

[0017] 2. This digital printing multi-color positioning device for fabrics uses a fourth motor in the fine-tuning device to drive the second gear to rotate, which meshes with the second rack on the crossbeam, allowing the mounting plate to move smoothly on the crossbeam and further fine-tune the position of the printing machine. Through these two adjustments, this device can easily adapt to fabrics of different sizes and printing position requirements. Whether it is large-format curtain fabric or small-sized clothing fabric, it can quickly and accurately complete the printing positioning, improving the versatility and production efficiency of the equipment and reducing production costs.

[0018] 3. This digital printing multi-color positioning device for fabrics uses a fan installed inside the placement plate to generate airflow through the air inlet and outlet, which adsorbs and fixes the fabric placed on it. Traditional technologies may use simple clamps or pressure blocks to fix the fabric, which can easily damage the fabric and has limited fixing effect. The fabric may still shift during the printing process. The fabric fixing method of this device is more reliable and can effectively prevent the fabric from moving during the printing process, ensuring the integrity and clarity of the printed pattern and improving the consistency and stability of the printing effect.

[0058] Instructions for use

[0059] The first threaded screw 10 in the slot at the top center of the base 1 is driven to rotate by the first motor 11. Since the connecting block at the bottom of the moving plate 2 cooperates with the first threaded screw 10, and the first slide rods 9 on both sides guide the moving plate 2, according to the principle of thread transmission, the rotation of the first threaded screw 10 will drive the moving plate 2 to move smoothly along the direction of the first slide rods 9 on the base 1, thereby initially adjusting the position of the placement plate 3 and improving the positioning accuracy of the fabric in the printing process. The second threaded screw 13 at the top center of the moving plate 2 is driven to rotate by the second motor 14. The connecting block at the bottom of the placement plate 3 cooperates with the second threaded screw 13, and the second slide rod 12 guides the placement plate 3. The rotation of the second threaded screw 13 causes the placement plate 3 to move horizontally along the direction of the second slide rod 12 on the moving plate 2, thereby realizing secondary adjustment of the height and horizontal position of the placement plate 3, further improving the flexibility and accuracy of fabric positioning. When the fan 23 installed inside the placement plate 3 is working, it draws in air from the multiple sets of air inlets at the top of the placement plate 3, and then blows it out from the air outlet through the air duct, forming an adsorption force on the surface of the placement plate 3, which firmly fixes the fabric placed on it, preventing the fabric from shifting during the printing process and ensuring the printing effect. The sliding plate 15 at the top of the first slide groove 4 and the second slide groove 5, wherein the third motor 16 at one end of the sliding plate 15 on the first slide groove 4 drives the first gear 17 to rotate. Since the first gear 17 meshes with the first rack 18, the rotation of the first gear 17 causes the sliding plate 15 to slide stably along the first slide groove 4 and the second slide groove 5. This movement, via the connecting column, drives the crossbeam 6 to translate, facilitating the adjustment of the printing machine 8's horizontal position to accommodate printing needs of fabrics of different sizes. A mounting plate 7 is slidably mounted on the third slide groove 22 at the top of the crossbeam 6. A fourth motor 19 at one end of the mounting plate 7 drives the second gear 20 to rotate. The second gear 20 meshes with the second rack 21 on the crossbeam 6, causing the mounting plate 7 to move smoothly on the crossbeam 6. This further fine-tunes the position of the printing machine 8 mounted on the mounting plate 7, meeting the requirements for high-precision adjustment of the printing position during the printing process.
