• Functional features: This screen printing machine can realize the unwinding operation of multiple ribbons at the same time. Through a special unwinding mechanism, each unwinding shaft has an independent tension control device to ensure that the tension of each ribbon is uniform and the speed is consistent during the unwinding process. For example, when printing 5 ribbons at the same time, the unwinding system can release each ribbon at a stable speed and appropriate tension according to the set parameters, preparing for subsequent synchronous printing.
• Advantages: Greatly improve production efficiency, can handle multiple ribbons at one time, suitable for large-scale ribbon screen printing production. Moreover, synchronous unwinding can ensure that the state of the ribbon is relatively consistent when entering the printing process, which is conducive to improving the consistency of printing quality.
2. Automatic positioning
• Positioning method and principle: Use advanced sensor technology, such as photoelectric sensors or mechanical positioning devices, to automatically position each ribbon. When the ribbon passes through the positioning area, the sensor detects the edge position of the ribbon or the pre-set mark point, and feeds back the position information to the control system. Based on this information, the control system adjusts the synchronous belt conveyor or other positioning mechanisms to ensure that the ribbon is always in the correct position during the printing process.
• Importance: Accurate positioning is crucial for ribbon silk screen printing. When printing patterns or text, if the ribbon position is inaccurate, it will cause quality problems such as pattern misalignment and deformation. The automatic positioning system can effectively avoid these situations and ensure the accuracy and beauty of the printed pattern.
3. Photoelectric color tracking
• Working principle: The photoelectric color tracking system detects the color change of the ribbon through a high-precision photoelectric sensor. During the printing process, the sensor monitors the color of the printed pattern on the ribbon in real time and compares the color information with the preset standard color. If a color deviation is found, the signal will be immediately fed back to the servo three-color silk screen system.
• Function: This system can ensure the accuracy and consistency of the printed color. For ribbons, ribbons or hat decorative ribbons with high color requirements, such as brand logo colors, specific decorative pattern colors, etc., photoelectric color tracking can adjust the printing color in time to ensure product quality and meet customer requirements for color accuracy.
4. Servo three-color screen printing
• Servo control principle: The servo three-color screen printing system uses a servo motor to accurately control the printing process of three colors of ink. The servo motor can accurately drive the movement of the screen printing scraper, including the control of parameters such as speed, stroke and pressure. For each color printing, the servo motor can accurately transfer the corresponding ink to the ribbon through the screen according to the set pattern and color requirements.
• Advantages: High-precision and complex three-color printing can be achieved. Through the precise control of the servo motor, the three colors of ink can be evenly distributed, the pattern edges are clear, and the color transition is natural. For example, when printing patterns with gradient color effects or trademarks with multiple color combinations, the servo three-color screen printing system can play a good role and improve the decorativeness and added value of the product.
5. Synchronous belt conveyor
• Conveying process: The ribbon is conveyed by the synchronous belt throughout the screen printing process. The synchronous belt has good transmission accuracy and stability, which can ensure that the ribbon passes through various processes such as unwinding, positioning, printing, drying and winding at a uniform speed. The surface of the synchronous belt usually has a certain friction, which can effectively prevent the belt from slipping or deflecting during the conveying process.
• Importance: Stable conveying is the key link to ensure the quality and efficiency of screen printing. It can keep the belt flat and tensile during printing, which is conducive to the uniform adhesion of ink and the accurate printing of patterns. At the same time, synchronous belt conveying also helps to realize the automation and continuity of the entire screen printing process.
6. IR tunnel drying
• Drying principle: IR tunnel drying is to use infrared radiation to quickly dry the printed belt. When the belt passes through the IR tunnel, the infrared can penetrate the ink layer, so that the solvent in the ink evaporates quickly, and the resin and other components are quickly solidified. The infrared radiation intensity and temperature in the IR tunnel can be adjusted according to factors such as the type of ink, the material of the belt and the printing speed.
• Advantages: This drying method is efficient and can dry and solidify the ink in a short time, greatly improving production efficiency. Compared with traditional natural drying or hot air drying methods, IR tunnel drying can reduce drying time and prevent the belt from being contaminated or damaged while waiting for drying. At the same time, infrared drying can make the ink and the ribbon better combined, enhancing the ink's adhesion and wear resistance.
7. Automatic winding
• Winding mechanism: After the ribbon is printed and dried, the automatic winding device will roll up the ribbon neatly. The winding device drives the winding roller through a motor and has automatic tension control and speed adjustment functions. It can adjust the winding tension and speed according to factors such as the thickness, width and material of the ribbon to ensure that the ribbon can be rolled tightly and neatly.
• Advantages: Automatic winding reduces manual operation and improves production efficiency and product quality. It can continuously carry out winding work, avoiding the accumulation of ribbons on the production line, and facilitating subsequent packaging and storage. At the same time, automatic winding can ensure the quality of the ribbon roll, which is convenient for transportation and use.

Application︰
Ribbon is a narrow or tubular fabric made of various yarns, usually in the form of a disc of unlimited length. Yarn can be natural fibers such as cotton and linen, or chemical fibers such as polyester, nylon, polypropylene, and spandex. Some shoulder straps of underwear and decorative belts of home clothes use cotton webbing, and some handles of linen handbags are natural fibers. Chemical fibers include: high-strength and durable luggage straps, straps for outdoor equipment, etc.; shoelaces, climbing safety belts, team logo belts, billboard belts; swimsuit straps, medical straps, trouser belts, hat decorative belts and yoga clothing decorative belts. Ribbon involves clothing, footwear, luggage, security, household goods, sporting goods, electronic equipment, outdoor decoration and other fields. Ribbon can be decorated by screen printing machine, hot stamping machine, embossing machine, and chemical transfer machine. The printing of webbing is a huge market, and many different printing processes are competing for this market, such as silk screen printing, heat transfer machines, bronzing, and dyeing. The silk screen is undoubtedly the printing method with the highest market share. The most prominent feature of the webbing screen printing machine is the workbench with a timing belt, that is, during the printing process, the webbing will be pasted on the workbench and move synchronously with the workbench. This structure makes it more suitable for flexible Printing of fabrics and even more elastic elastic bands. Screen printers with timing belts are also more suitable for multi-color overprinting, because they will not be deformed during the printing process. After the webbing is printed, there are also post-processing problems, such as the drying of the ink and the cutting of the length, which require special procedures to complete.
Advantages︰
The screen printing machine for printing continuous strips and roll materials belongs to the category of roll-to-roll screen printing machines. There are two main types. One is the screen printing machine for printing paper, film and other materials with good dimensional stability. It has the following characteristics: 1) The workbench adopts an aluminum alloy suction screen printing table. When the roll material is transported to the printing position according to a certain distance, the material stops moving, the suction action opens, and the printing is completed. Then, the roll material continues to be pulled forward. 2) The drying of the machine can use a winding drying furnace, which saves the space occupied by the machine under the condition of ensuring the drying of the material. Now there are also some product packages that use UV drying or UVLED drying. A curing unit can be installed in the post-printing process, and the UV ink is dried instantly, so the footprint of the machine is greatly reduced. 3) The photoelectric tracking switch is installed at the front of the machine table, and the single-color screen printing machine can perform overprinting of the second color. The machine can connect multiple monochrome machines to complete multi-color overprinting. This roll-to-roll screen printing machine is suitable for printing paper packaging, membrane switches, thermal transfer films and other products. With the development of the market, the functions of roll-to-roll machines have been greatly improved. For example, adding a thermal transfer unit can realize cold stamping. When printing thermal transfer film, the machine can be equipped with an automatic powder shaker unit, and some factories will Add die-cutting or cutting function. There is also a kind of screen printing machine with stretchability and elasticity such as printing ribbons. Its characteristics are as follows: 1) The workbench adopts a synchronous belt driven by a motor, and the product will move forward with the synchronous belt for a certain distance for printing, which avoids the graphic deformation caused by the expansion and contraction deformation of the product during printing. 2) Ribbon and other products are basically printed with thermosetting ink and glue, and the ink drying adopts IR drying process, and the length of the drying oven varies from 2 meters to 4 meters. Currently, webbing products rarely use UV curing process.
