Description

Technical Field

[0001] This utility model is a yarn frame system with inkjet printing function, belonging to the field of yarn frame machines. Background Technology

[0002] With the rapid development of the textile industry, consumers have increasingly higher demands for the aesthetics and functionality of fabrics. Traditional fabric dyeing methods, such as immersion dyeing and spray dyeing, while achieving color changes, often involve complex processes, high costs, and environmental impacts. Furthermore, these traditional methods may also affect the fabric's hand feel and durability.

[0003] While warp knitting offers high production speed and flexibility, it still has limitations in color processing. Traditional warp knitting techniques can mostly only produce products with a single color or simple patterns. To achieve more complex designs or color gradient effects, additional dyeing or printing processes are required after weaving. This not only increases production costs and complexity but can also lead to problems such as uneven dyeing.

[0004] To simplify production processes and reduce environmental pollution, the textile industry has been seeking methods to achieve color changes directly during weaving. For example, inkjet printing disperses pigment into tiny droplets using a spray gun or atomizer, uniformly spraying them onto the material surface to achieve a gradient effect from one color to another. However, this method is not only labor-intensive and resource-intensive but can also lead to environmental pollution and increased costs. On the other hand, while jacquard weaving can create gradient effects on fabrics through combinations of different yarns and stitch patterns, its drawing efficiency is low, requiring extensive manual drawing, which prolongs the production cycle, and the jacquard effect appears unnatural upon close inspection.

[0005] In recent years, with the development of digital inkjet printing technology, its application in the textile industry has become increasingly widespread. The advantages of digital inkjet printing technology lie in its ability to achieve highly customized pattern designs and the quick change of different patterns, greatly improving production flexibility. However, current inkjet printing technology is mainly applied to finished fabrics, with relatively little research on direct color processing during online production.

[0006] Furthermore, the post-dyeing treatment of yarn is also a crucial step. In traditional dyeing processes, the yarn's tension and crimp can change due to variations in moisture levels after dyeing, necessitating re-warping to restore tension consistency and morphological stability. This process not only increases production steps but can also potentially affect the quality of the final product.

[0007] To overcome these problems, researchers began exploring methods to integrate dyeing functions into yarn registries. Currently, some research focuses on how to set inkjet mechanisms at different locations on the yarn registry to achieve online dyeing. However, most of these methods fail to achieve independent dyeing and tension adjustment for each yarn, resulting in uneven dyeing effects and unstable tension control. Utility Model Content

[0008] The purpose of this invention is to provide a yarn frame system with inkjet printing function to solve the problems of uneven dyeing effect and unstable tension control in existing yarn frame machine integrated dyeing devices.

[0009] Those skilled in the art should understand that the "front end" and "back end" mentioned in this application are defined by the process of the yarn traveling from the yarn rack to the weaving equipment, rather than by the front end and back end in absolute spatial position. That is, the yarn rack is the front end of the whole process and the weaving equipment is the back end. It is assumed that the yarn first travels from the yarn rack to the yarn collecting plate, and after being collected, it enters the inkjet mechanism for dyeing and then enters the weaving equipment for weaving. In this application, the yarn collecting plate is located at the front end of the inkjet mechanism and the inkjet mechanism is located at the rear end of the yarn collecting plate, without considering the absolute position of the two devices in the actual environment.

[0010] This utility model is achieved through the following technical solution: a yarn rack system with inkjet printing function, including a yarn rack, an inkjet printing device and an inkjet control system. The yarn rack is provided with several yarn hanging rods, and each yarn hanging rod is correspondingly hung with a yarn tube. Several inkjet printing devices are also provided at the rear end of the yarn rack. The inkjet printing devices are wirelessly connected to the inkjet control system. The inkjet control system controls the inkjet printing devices to perform inkjet printing on the yarn output from the yarn tube.

[0011] Furthermore, a yarn collecting plate is provided between the yarn rack and the inkjet printing device.

[0012] Furthermore, the inkjet printing device is correspondingly located at the rear end of each yarn bobbin, and a yarn collecting plate is provided at the rear end of the yarn frame located at the output end of the inkjet printing device.

[0013] Furthermore, the inkjet printing device includes a housing, a yarn inlet, an inkjet mechanism, and a yarn outlet. The yarn inlet is located on the end face of the housing facing the yarn tube, and the yarn outlet is located on the end face of the housing facing away from the yarn tube.

[0014] Furthermore, a yarn drying mechanism is provided between the inkjet printing mechanism and the yarn outlet of the inkjet printer.

[0015] Furthermore, a tension adjustment mechanism is provided between the yarn drying mechanism and the yarn outlet of the inkjet printing device.

[0016] Furthermore, a tension adjustment mechanism is provided between the yarn inlet of the inkjet printing device and the inkjet mechanism.

[0017] Furthermore, a yarn drying mechanism is provided at the rear end of the yarn rack behind the inkjet printer.

[0018] Furthermore, a tension adjustment mechanism is provided at the rear end of the yarn rack located after the yarn drying mechanism.

[0019] Furthermore, a tension adjustment mechanism is provided between the inkjet printing unit and the yarn spool. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 and Figure 6As shown, a yarn rack system with inkjet printing function includes a yarn rack 1, an inkjet printing device 2, and an inkjet control system 6. The yarn rack 1 is provided with several yarn hanging rods 11, and each yarn hanging rod 11 is connected to a corresponding yarn tube 111. Several inkjet printing devices 2 are also provided at the rear end of the yarn rack 1. The inkjet printing devices 2 are wirelessly connected to the inkjet control system 6. The inkjet control system 6 controls the inkjet printing devices 2 to perform inkjet printing on the yarn output from the yarn tube 111.

[0024] like Figure 2 As shown, when the on-site environment is limited and it is necessary to collect the yarn before inkjet dyeing, a yarn collecting plate 3 is provided between the yarn rack 1 and the inkjet printing device 2.

[0025] like Figure 4 As shown, when the on-site environment permits, the inkjet printing mechanism can be set up in accordance with the yarn tube 111, and the scheme of inkjet printing first and then yarn collection can be implemented. The inkjet printing device 2 is set at the rear end of each yarn tube 111, and the yarn frame 1 located at the output end of the inkjet printing device 2 is provided with a yarn collection plate 3.

[0026] like Figure 7 As shown, in order to achieve inkjet printing of yarn, the inkjet printing device 2 should at least include a housing 21, a yarn inlet 22, an inkjet mechanism 23, and a yarn outlet 24. The yarn inlet 22 is located on the end face of the housing 21 facing the yarn tube 111, and the yarn outlet 24 is located on the end face of the housing 21 away from the yarn tube 111.

[0027] If the distance from the yarn frame 1 to the warp knitting machine is short due to on-site environmental reasons, the yarn after inkjet printing should be dried in time. The inkjet printing device 2 should be equipped with a yarn drying mechanism 4. Firstly, the yarn drying mechanism 4 can be set between the inkjet mechanism 23 and the yarn outlet 24 of the inkjet printing device 2; secondly, the yarn drying mechanism 4 can be set outside the inkjet printing device 2, preferably at the rear end of the yarn frame 1, that is, at the position between the yarn frame 1 and the warp knitting machine.

[0028] Since the tension of the yarn may change after drying, the tension of the dried yarn should be uniform. A tension adjustment mechanism 5 should be provided. There are two ways to install the tension adjustment mechanism 5. First, the tension adjustment mechanism 5 can be integrated into the inkjet printing device 2. The tension adjustment mechanism 5 is located between the yarn drying mechanism 4 and the yarn outlet 24 inside the inkjet printing device 2. Second, when the yarn drying mechanism 4 is located outside the inkjet printing device 2, the tension adjustment mechanism 5 should also be located outside the inkjet printing device 2, that is, behind the yarn drying mechanism 4 between the yarn frame 1 and the warp knitting machine, close to the warp knitting machine.

[0029] To ensure uniform color of all yarns during inkjet dyeing, the tension should be adjusted to be consistent before the yarns enter the inkjet printing device 2. Therefore, a tension adjustment mechanism 5 should be installed before inkjet printing. There are two ways to install the tension adjustment mechanism 5 before inkjet printing: First, the tension adjustment mechanism 5 can be integrated into the inkjet printing device 2, located between the yarn inlet 22 and the inkjet mechanism 23 inside the inkjet printing device 2; Second, the tension adjustment mechanism 5 can be installed between the inkjet printing device 2 and the yarn tube 111.

[0030] Example 1: like Figure 2 , Figure 3 , Figure 7 As shown, the inkjet printing device 2 sprays ink onto the yarn collected by the yarn collecting plate 3: Example 1: Basic Configuration: (1) Equipment installation: In this embodiment, a yarn hanging rod 11 is provided on the yarn frame 1, and a yarn tube 111 is provided on the yarn hanging rod 11; an inkjet printing device 2 is provided in front of the rear end side of the yarn frame 1, and a yarn collecting plate 3 is provided between the inkjet printing device 2 and the yarn frame 1, and the yarn collecting plate 3 and the inkjet printing device 2 are located on the same horizontal plane.

[0031] (2) Collecting silk threads: The yarn starts from the yarn tube 111 on the yarn hanging rod 11 at the front end of the yarn frame 1. Under the winding action of the yarn tube 111, the yarn begins to move. As the yarn tube 111 rotates and releases the yarn, the yarn moves backward and is gradually guided to the yarn collecting plate 3 located in the middle of the yarn frame 1. On the yarn collecting plate 3, the yarn is guided and arranged to ensure that it enters the inkjet printing device 2 with uniform spacing and tension.

[0032] (3) Inkjet: After the yarn is collected on the yarn collecting plate 3, it enters the inkjet printing device 2, which performs inkjet printing on the yarn to complete the dyeing of the yarn.

[0033] This embodiment adopts the step of collecting yarn first and then dyeing. The yarn after collecting yarn is in a stable state and can better adapt to different dyeing processes and pattern requirements. In addition, its neat arrangement and consistent tension allow the dye to adhere more evenly to the yarn surface, thus improving the dyeing quality.

[0034] Example 2: Functional mechanisms are integrated inside: In this embodiment, the tension adjustment mechanism 5 and the yarn drying mechanism 4 are integrated into the inkjet printing device 2. The specific workflow is as follows: The yarn enters through the yarn inlet 22 of the inkjet printer 2, first passing through the tension adjustment mechanism 5 to guide it and prevent it from becoming loose or cracked due to improper tension during subsequent inkjet printing. It then enters the inkjet mechanism 23, which, under the control of the inkjet control system 6, precisely sprays ink onto the yarn according to preset patterns and markings, ensuring the ink adheres tightly to the yarn fiber surface to form the pattern or marking. After inkjet printing, the yarn enters the yarn drying mechanism 4, where the hot air circulation system accelerates the ink drying process. As heat is transferred, the ink gradually penetrates and fixes onto the yarn fibers, restoring the yarn to a dry state. The dried yarn then enters another tension adjustment mechanism 5, where further tension adjustment ensures the yarn is output from the yarn outlet 24 of the inkjet printer 2 in a stable state.

[0035] In this embodiment, the functional mechanisms are located inside the inkjet printing device 2, which effectively reduces the footprint of the equipment. The integrated design makes the connection between the functional mechanisms closer, eliminating the need to consider the fixing and connection of the functional mechanisms, and reducing the equipment installation steps and time.

[0036] Example 3: Functional mechanisms integrated externally: Based on Embodiment 1, this embodiment adds a yarn drying mechanism 4 and a tension adjusting mechanism 5 at the rear end of the yarn frame 1. Unlike Embodiment 2, the tension adjusting mechanism 5 and the yarn drying mechanism 4 are located outside the inkjet printing device 2. The specific workflow is as follows: The yarn is released from the yarn tube 111 on the yarn hanging rod 11 at the front end of the yarn frame 1. It first passes through the yarn collecting plate 3 for yarn collection and sorting. Then the yarn enters the tension adjusting mechanism 5 for further tension adjustment. After the tension is adjusted, it enters the inkjet printing device 2 for dyeing. The dyed yarn is output from the yarn outlet 24 of the inkjet printing mechanism and enters the external yarn drying mechanism 4 for drying. Then the dried yarn enters the tension adjusting mechanism 5 for use in subsequent weaving.

[0037] In this embodiment, the functional mechanisms are located outside the inkjet printing device 2. When maintenance or replacement of the functional mechanisms is required, there is no need to disassemble or move the complex components inside the inkjet printing device 2, which greatly reduces maintenance time or workload. Furthermore, the parameters or categories of each functional mechanism can be adjusted in a timely manner according to different yarn types or different task requirements.

[0038] Example 2: like Figure 4 , Figure 5 , Figure 7As shown, the inkjet printing device 2 sprays ink onto the yarn at the yarn exit of the yarn tube 111. The specific weaving direction of the yarn is as follows: Example 1: Basic Configuration: (1) Equipment installation: In this embodiment, the front end of the yarn frame 1 is provided with a yarn hanging rod 11, and the yarn hanging rod 11 is provided with a yarn tube 111; the rear end of the yarn frame 1 is provided with an inkjet printing device 2, and the rear end of the yarn frame 1 at the output end of the inkjet printing device 2 is provided with a yarn collecting plate 3.

[0039] (2) Staining: The yarn starts from the yarn tube 111 on the yarn hanging rod 11 at the front end of the yarn frame 1. Under the winding action of the yarn tube 111, it begins to move. As the yarn tube 111 rotates and releases the yarn, the yarn moves backward and is gradually guided into the inkjet printing device 2, where the yarn is dyed.

[0040] (3) Collecting silk threads: After being processed by the inkjet printing device 2, the yarn enters the yarn collecting plate 3 for adjustment, so that the yarn is arranged neatly and can be used in the subsequent weaving process.

[0041] This embodiment adopts a dyeing-then-gathering step, directly dyeing the yarn coming out of the yarn package 111. This allows the dye to adhere more naturally to the yarn that has not been subjected to excessive tension and finishing, forming a unique color effect. Furthermore, in scenarios where high production efficiency is required, the dyeing-then-gathering method can reduce the preparation time increased by the finishing of the yarn gathering plate 3 in the early stage, improve production efficiency, and meet market demand more quickly.

[0042] Example 2: Functional mechanisms are integrated inside: In this embodiment, the tension adjustment mechanism 5 and the yarn drying mechanism 4 are integrated in the inkjet printing device 2. Similar to embodiment 2 in embodiment 1, after the yarn enters from the yarn inlet 22 of the inkjet printing device 2, it passes through the tension adjustment mechanism 5, the inkjet mechanism 23, the yarn drying mechanism 4 and another tension adjustment mechanism 5 in sequence, and finally exits through the yarn outlet 24.

[0043] By integrating the functional mechanisms, the dyeing step is closely connected with the subsequent yarn collection process, avoiding tension changes or color staining caused by issues such as the distance between devices or the connection method. This improves the efficiency of the entire production process. Furthermore, this setup facilitates the automation and continuous production of yarn dyeing and yarn collection, reduces manual intervention, and improves overall production efficiency and product quality.

[0044] Example 3: Functional mechanisms integrated externally: Based on Embodiment 1, this embodiment includes a tension adjustment mechanism 5 between the yarn bobbin 111 and the inkjet printing device 2, and a yarn drying mechanism 4 and a tension adjustment mechanism 5 are located at the rear end of the yarn frame 1 after the inkjet printing device 2. Unlike Embodiment 2, the tension adjustment mechanism 5 and the yarn drying mechanism 4 are located outside the inkjet printing device 2. The specific working process is as follows: This application provides a tension adjustment mechanism 5 between the yarn spool 111 and the inkjet printing device 2, ensuring that the yarn tension entering the inkjet printing device 2 remains consistent. This effectively stabilizes the yarn tension and prevents yarn breakage or uneven dyeing caused by tension fluctuations. By externalizing the yarn drying mechanism 4 and the tension adjustment mechanism 5 to the inkjet printing device 2, maintenance and adjustment are facilitated, while also allowing for flexible adaptation to production needs, thus enhancing the reliability and flexibility of the equipment in actual production processes.

[0045] Example 3: The external inkjet control system 6 in this application coordinates and controls the inkjet printing device 2, the tension adjustment mechanism 5, and the yarn drying mechanism 4 to ensure that the entire dyeing process is efficient, accurate, and stable.

[0046] Through precise algorithms and real-time monitoring technology, this system can synchronously drive the printhead in the inkjet printer 2 to precisely jet ink according to the preset dyeing pattern, color gradient, and process parameters. At the same time, it can adjust the tension adjustment mechanism 5 in real time to ensure that the yarn maintains a constant and appropriate tension during the inkjet process, preventing yarn breakage or uneven dyeing due to uneven tension. In addition, the system is also responsible for managing the yarn drying mechanism 4, precisely setting the drying temperature, wind speed, and drying time according to the yarn material and ink type, ensuring that the ink can quickly and evenly penetrate and fix on the yarn fibers, while avoiding over-drying that could damage the yarn performance.

[0047] Throughout the entire process, the inkjet control system 6 continuously collects data from various devices, such as the real-time tension value of the tension sensor and the temperature changes of the drying device. Based on this data, it makes intelligent adjustments and optimizations to ensure the continuity and stability of the entire production process, thereby significantly improving the quality and production efficiency of yarn dyeing.
