Description

Improved inkjet printing device for printing stretchable materials

technical field

The utility model relates to an improved ink-jet printing device capable of printing stretchable materials, especially stretchable cloth materials. This improved inkjet printing device is an improvement on the current general inkjet printing machine. It is equipped with components such as cloth feeding, cloth receiving, cloth feeding servo and cloth receiving servo to overcome the uniform expansion and contraction of the entire surface of the cloth, so that the stretchable printing material can overcome printing. The degree of difficulty enables stretchable fabrics to be ink-jet printed as precisely as flat paper.

Background technique

Most of the materials commonly used in inkjet printing are paper with a stretch rate close to zero. Because the material of the paper is flat and held by the holder of the printer, the pattern pattern to be printed can be printed on the paper through the nozzle of the inkjet printer through the fine nozzle. The nozzles of the current inkjet printers move the nozzles horizontally to scan and print the ink onto the material to be printed. The stretch rate of the material to be printed affects the quality of the printing to a great extent. Since the accuracy of moving the nozzle back and forth in the lateral direction and the accuracy of paper advancement must be synchronized and precise, the continuous graphics of the pattern can be printed flawlessly. Therefore, the shrinkage rate of the printed material must be close to the same regardless of its warp or weft direction, and there is no stretchability.

In the past, fabrics with large stretchability, such as fiber cloth among various materials, were printed. Due to their high stretchability, inkjet printing could not be carried out with the paper clamp on the printer like paper, and the printing stretchability was relatively high. For fiber materials, most of them use screen printing, please refer to Figure 1 for details. Place the material to be printed on the bottom and use a rubber knife to make the ink pass through the mesh of the screen to print the ink on the fiber material. This type of screen printing is used for high-speed, less precise mass printing. Its disadvantage is that its precision cannot reach the precision of inkjet printing, and it is also not suitable for the production of a small number of special-order printed items.

If the cloth with large stretchability is printed with an inkjet printing machine, the cloth cannot be pinched by the gripper on the printing machine due to the large or uneven shrinkage in the warp and weft directions, and the printed product will not be produced properly. Flat, deformed, or the cloth is often scratched by the paper clipper, or the inkjet remaining material sprayed out reverses from the rear to the front, so that the printed cloth is stained, the pattern or pattern is blurred, and even the positioning is inaccurate. Lines produce double shadows and so on.

The current inkjet printing machines on the market (for example, Dupont Artistic 2020 priler, see Figure 2 for details) are dedicated to printing stretchable materials. Two sets of rollers are placed on both sides of the machine. Use the glue pool to dip the blanket belt with glue for multiple times, and then drive the fiber material to be printed through the blanket belt through the rollers and closely combine with the top of the blanket belt to overcome the fact that the printed material no longer stretches and makes the printed material The shrinkage of the printed cloth material becomes as stable as that of paper material, and it will not cause deformation and printing defects as mentioned above. However, this printing machine will be printed on the blanket after many times of printing. It also makes the printed materials not easy to adhere to the blanket, thus causing various difficulties in printing. At the same time, after the finished printed product is completed, it still needs to be processed and cleaned to remove the glue.
