Description

Technical Field

[0001] This utility model relates to the field of precious metal textiles, and in particular to an embroidery composite device. Background Technology In recent years, precious metal embroidery composite devices have been widely used in high-end textiles, smart wearable devices, and luxury decoration. These devices introduce precious metal threads into traditional embroidery techniques, giving the embroidered pieces both aesthetic value and functionality. However, existing precious metal embroidery devices still have significant technical deficiencies in thread tension and guidance control, affecting embroidery accuracy and efficiency.

[0002] In traditional embroidery machines, the thread, after exiting the thread guide, typically enters the needle area directly without a tension wheel or dynamic tension adjustment mechanism. Because precious metal threads are highly rigid and elastic, they are prone to uneven stitches due to slack during high-speed embroidery. Tension fluctuations can cause the metal thread to form loops of varying tightness on the fabric, affecting the appearance of the embroidery. Furthermore, without tension control, the metal thread is easily broken by sudden pulling or vibration. In addition, while some improved embroidery machines have added a tension wheel behind the thread guide, the tensioned thread lacks a stable guiding structure, causing it to deviate from its intended path. This unguided thread is prone to straying from the center of the needle eye, leading to skipped stitches or thread tangling.

[0003] Therefore, it is necessary to provide an embroidery composite device that can effectively prevent tension shifting of the thread and prevent skipped stitches and thread tangling. Utility Model Content

This allows the tension of the thread on the device to be effectively controlled by the tensioning wheel, preventing breakage or loosening of the thread due to tension fluctuations during high-speed embroidery. Furthermore, the thread enters the embroidery needle along the first direction through the guide groove, ensuring that the thread follows a preset path into the needle, preventing the thread from slipping off the path and avoiding skipped stitches and thread tangling.

[0020] Please refer to Figure 1 - Figure 5 One embodiment of this application provides an embroidery composite device 100, the device 100 comprising: The substrate 10, the winding part 20, and the embroidery part 30.

[0021] The winding portion 20 is slidably connected to the base plate 10, and the winding portion 20 is fixedly connected to the winding portion 21. The embroidery portion 30 is fixedly connected to the base plate 10 and to the winding portion 20. The embroidery portion 30 is slidably connected to the machine head 31, and the machine head 31 is fixedly connected to the tension wheel 31A. It also integrally forms a guide groove 31B extending along the first direction F1, and an embroidery needle 31C located on the side of the guide groove 31B opposite to the tension wheel 31A. The winding portion 21 winds the thread, and the thread winds around the tension wheel 31A through the winding portion 21, and then passes through the tension wheel 31A and the guide groove 31B in sequence to enter the embroidery needle 31C along the first direction F1.

[0022] The winding section 20 is slidably connected to the base plate 10 and can be adjusted along the base plate 10 to adapt to different thread supply requirements. The winding section 21 is fixed to the winding section 20 and is used for the initial winding and positioning of the thread to ensure orderly release of the thread. Precious metal threads are prone to tangling or breakage due to disordered thread release. The fixed design of the winding section 21 can prevent the thread from becoming tangled, while the sliding winding section 20 allows for dynamic adjustment of the thread supply angle. The embroidery section 30 is fixed to the base plate 10 to provide stable support; the machine head 31 is slidably connected to the embroidery section 30 to achieve precise movement of the embroidery needle 31C. The tension wheel 31A is fixed to the machine head 31 and directly controls the thread tension; the guide groove 31B guides the thread into the embroidery needle 31C along the first direction F1 (the direction from the thread outlet of the tension wheel 31A to the thread hole of the embroidery needle 31C). When the machine head 31 moves, it synchronously drives the tension wheel 31A to dynamically maintain the thread tension. The thread is forced to enter the embroidery needle 31C along a fixed path, preventing deviations caused by the elasticity or hardness of the precious metal thread. The thread passes sequentially through the winding section 21, the tension wheel 31A, and the guide groove 31B before entering the embroidery needle 31C. The winding section 21 prevents sudden pulling during thread release, the tension wheel 31A buffers tension fluctuations in real time, and finally, the guide groove 31B eliminates lateral deviation of the thread, ensuring the piercing accuracy of the embroidery needle 31C. This sophisticated design also adapts to the characteristics of precious metals; for example, the high hardness of the metal thread requires fewer bends in the path, and the straight design of the guide groove 31B reduces bends and friction. Due to its high hardness and poor ductility, the metal thread is prone to breakage or uneven tension in a device 100 without tension adjustment. The tension wheel 31A is linked to the head 31; when the head 31 moves during embroidery, the tension wheel 31A moves accordingly, maintaining consistent tension. The guide groove 31B, in addition to its guiding function, also restricts the freedom of the thread, preventing sudden stress caused by swaying. Traditional manual thread path adjustments are inefficient and inconsistent. This solution integrates the guide groove 31B into the machine head 31, ensuring a consistent thread path for each embroidery stitch and reducing skipped stitches or thread deviation. The winding section 20 slides between the winding section 20 and the embroidery section 30, allowing for quick thread changes or adjustments to the thread type.

[0023] More preferably, the device 100 further includes a base 40.

[0024] The substrate 10 is slidably connected to the base 40. The base 40 extends along the second direction F2, and a first slide rail 41 is integrally formed on the base 40 along the second direction F2. The substrate 10 slides on the base 40 along the first slide rail 41.

[0025] The addition of the base 40 structure and the provision of the first slide rail 41 are intended to expand the overall degree of freedom of movement of the device 100. The base 40 serves as the supporting foundation for the entire device 100, and its first slide rail 41, extending along a second direction F2 parallel to the ground, allows the substrate 10 to slide flexibly in the horizontal direction. This design significantly expands the range of embroidery operations, enabling the equipment to... This allows for wider embroidery patterns while maintaining overall structural stability. By sliding the base plate 10 on the base 40, the operator can easily adjust the embroidery area without moving the entire device 100 or re-fixing the embroidery frame. The one-piece molded first slide rail 41 design offers significant technological advantages. The integrated structure avoids assembly errors, ensuring the straightness and precision of the slide rail, which is particularly crucial for high-precision operations such as precious metal embroidery. The precise guiding characteristics of the slide rail ensure the stability of the base plate 10 during movement, preventing stitch misalignment due to vibration or displacement. This design also enhances the durability of the equipment, reducing potential track wear or loosening issues after long-term use. From a functional perspective, this sliding connection enables multi-level coordinated control. The sliding system of the base 40 and base plate 10, together with the sliding of the winding section 20 on the base plate 10, forms a composite motion mode, allowing the thread supply path to be adjusted two-dimensionally according to embroidery requirements. For example, when embroidering complex curved patterns, the lateral movement of the base plate 10 can be coordinated with the longitudinal adjustment of the winding section 20 to always maintain the optimal relative position between the thread and the embroidery needle 31C. This dynamic coordination capability is particularly important for precious metal threads, as the low ductility of metal threads requires more precise path control.

[0026] More preferably, the substrate 10 extends along a third direction F3 perpendicular to the second direction F2, and the substrate 10 is integrally formed with a second slide rail 11 along the third direction F3.

[0027] The design of the second slide rail 11, extending in a third direction F3 perpendicular to the ground, is primarily based on in-depth considerations of embroidery precision and functional expansion. By adding a vertical second slide rail 11 to the first slide rail 41, the device 100 achieves true two-dimensional planar motion capability, which is particularly important for complex embroidery processes. Precious metal thread embroidery often requires handling delicate curves and corners. The dual-slide rail structure allows the substrate 10 to move freely in two planes, ensuring that the thread always enters the embroidery needle 31C area at the optimal angle, avoiding thread twisting or uneven tension caused by movement in a single direction. From a mechanical design perspective, the integral molding of the second slide rail 11 continues the precision advantage of the first slide rail 41. The two mutually perpendicular slide rails together constitute a high-precision planar motion system, and their orthogonal design ensures the independence of the two axial movements, effectively eliminating motion interference. This structure is particularly suitable for handling precious metal threads, because materials such as gold and silver require extremely high accuracy in their motion trajectories; even a micrometer-level deviation can lead to uneven stitches or surface scratches. The one-piece molded slide rail avoids the cumulative errors common in assembled structures, allowing the equipment to maintain its initial accuracy even after long-term use. The dual-slide rail design gives the device 100 more flexible spatial adjustment capabilities. The winding section 20 can move longitudinally along the second slide rail 11, coordinating with the lateral movement of the base plate 10, enabling the thread supply system to dynamically track changes in the position of the embroidery needle 31C. When embroidering complex patterns, the system can adjust the thread introduction angle and tension distribution in real time through two-axis linkage, which is crucial for maintaining the flatness and luster of precious metal threads. For example, when embroidering sharp angles, the longitudinal slide rail can fine-tune the position of the winding section 20 to compensate for thread slack caused by sudden changes in direction. Operators can quickly locate specific embroidery areas through dual-axis movement, simplifying the tedious process of repeatedly adjusting the embroidery frame required by traditional equipment. For mass production scenarios, this structure facilitates automated control.

[0028] More preferably, the winding portion 20 is embedded in the second slide rail 11 and slides along the second slide rail 11 on the substrate 10.

[0029] This design integrates the wire supply system and the substrate 10 by directly embedding the winding section 20 into the second slide rail 11. Precise coordination of movement. The sliding of the winding section 20 along the guide rail dynamically adjusts the thread release angle, ensuring that the precious metal thread always enters the embroidery area along the optimal path, avoiding thread twisting or additional friction caused by a fixed thread supply position. The embedded structure enhances the system's rigidity, preventing vibration interference during high-speed embroidery, while simplifying mechanical complexity and making maintenance easier. This integrated design is particularly suitable for handling high-value precious metal threads, ensuring both embroidery precision and extending thread lifespan.

[0030] More preferably, the embroidery part 30 further includes a pneumatic part 32.

[0031] The pneumatic unit 32 is fixedly connected to the embroidery unit 30 and is located on the side of the embroidery unit 30 opposite to the machine head 31. The pneumatic unit 32 drives the machine head 31 to slide along the third direction F3.

[0032] Among these advantages, pneumatic drive is more suitable for embroidery scenarios than traditional motors. It provides a gentle and immediate thrust response, preventing precious metal threads from breaking due to sudden start-stop. Secondly, placing the pneumatic unit 32 on the back of the embroidery unit 30 (away from the head 31) saves space and balances the center of gravity of the device 100, ensuring stability during high-speed embroidery. Most importantly, the pneumatic unit 32 drives the head 31 in the third direction F3 (longitudinal), which can coordinate with the lateral sliding of the base plate 10 to make thread tension adjustment more precise. For example, when embroidering at a corner, the pneumatic unit 32 can fine-tune the position of the head 31 in real time to compensate for the stress concentration caused by the change in direction of the metal thread. This dynamic compensation capability is difficult to achieve with mechanical linkage mechanisms.

[0033] More preferably, the pneumatic part 32 includes: a push rod 32A and a push block 32B.

[0034] One end of the push rod 32A is slidably connected to the pneumatic part 32 and passes through the embroidery part 30 along the third direction F3. The push block 32B is fixedly connected to the other end of the push rod 32A and is located on the side of the push rod 32A away from the pneumatic part 32.

[0035] The combination of push rod 32A and push block 32B in the pneumatic unit 32 achieves precise control of the movement of the machine head 31 through precise mechanical linkage. As the core component for power transmission, the push rod 32A's layout, running through the embroidery section 30, ensures linearity in force transmission while fully utilizing the internal space of the equipment, resulting in a more compact overall structure. The sliding connection between the push rod 32A and the pneumatic unit 32 ensures smooth movement, making it particularly suitable for embroidery operations requiring high-frequency reciprocating motion. This design effectively reduces the backlash problem common in traditional threaded drives. The push block 32B, as a key transition component connecting the push rod 32A and the machine head 31, not only plays a role in power transmission but also maintains the rigidity of the entire transmission system through its fixed connection characteristics. Positioning the push block 32B at the end of the push rod 32A brings the point of application of the driving force closer to the actual working position of the machine head 31. This short lever arm design significantly improves transmission efficiency and control precision, ensuring consistent stitch length and tension for each stitch. This structure offers unique advantages in dynamic response. When processing precious metal wires with different properties, the pneumatic system can quickly change the output force by adjusting the air pressure, and the rigid connection between the push rod 32A and the push block 32B can instantly transmit this adjustment to the machine head 31. For example, the air pressure is increased when embroidering harder gold thread and decreased when embroidering softer silver thread. This real-time adjustable driving force characteristic, combined with the positioning function of the guide groove 31B, allows the equipment to adapt to the processing requirements of various precious metal materials. At the same time, the planar contact design of the push block 32B, compared with the traditional point contact method, can distribute the load more evenly and extend the service life of the mechanism.

[0036] More preferably, the machine head 31 further includes a fixing part 31D.

[0037] The fixing part 31D is fixedly connected to the push block 32B and is located on the side of the push block 32B opposite to the push rod 32A. The fixing part 31D is also fixedly connected to the winding part 20.

[0038] The fixing part 31D, serving as a rigid connecting bridge between the pusher 32B and the winding part 20, ensures the lossless transmission of aerodynamic force from the pneumatic part 32 to the winding part 20, making the tension adjustment response more direct. Secondly, by rigidly coupling the winding part 20 to the movement of the head 31, the thread release speed can be completely synchronized with the movement of the needle 31C, avoiding the loosening or over-tightening of precious metal threads due to asynchronous movement. Finally, this integrated design significantly improves the structural stability of the system. When handling high-strength metallic thread embroidery, the fixing part 31D effectively suppresses vibration, ensuring the uniformity of each stitch.

[0039] More preferably, when the pneumatic part 32 drives the push rod 32A to move along the third direction F3, the fixing part 31D drives the winding part 20 to also move along the third direction F3.

[0040] In this design, the third direction F3 is the vertical direction perpendicular to the base 40. This linkage design achieves coordinated movement between the thread supply system and the embroidery execution mechanism through mechanical coupling. When the pneumatic unit 32 drives the push rod 32A to move vertically, the fixed unit 31D synchronously drives the winding unit 20 to move, so that the thread release speed and the displacement of the embroidery needle 31C are matched in real time, completely solving the problem of metal thread accumulation or pulling caused by asynchronous movement in traditional equipment. Secondly, this rigid linkage mechanism ensures that the thread tension remains dynamically balanced throughout the embroidery process, especially when dealing with precious metal threads with poor ductility, effectively preventing thread breakage and uneven stitches. This design controls the machine head 31 and the winding unit 20 simultaneously through a single drive source, which simplifies the complexity of the control system and ensures precise synchronization of motion parameters, allowing the equipment to maintain the thread length accuracy even under high-speed embroidery.

[0041] More preferably, the embroidery part 30 further includes a limiting rod 33.

[0042] The limiting rod 33 is fixedly connected to the embroidery part 30 and is located on the side of the embroidery part 30 opposite to the pneumatic part 32. The limiting rod 33 extends along the third direction F3 and passes through the push block 32B. The push block 32B is slidably connected to the limiting rod 33 to limit the push block 32B.

[0043] The limiting rod 33 and the pneumatic part 32 are symmetrically distributed on both sides of the embroidery part 30, forming a stable double-support structure. This effectively suppresses the lateral vibration of the push block 32B during high-speed movement, preventing deviations in the routing path of the precious metal wire. Secondly, the sliding connection of the rod through the push block 32B preserves the necessary degree of freedom of movement in the third direction F3 while strictly limiting displacement in other directions, preventing the push block 32B from deflecting due to inertia. This hard limiting mechanism serves as a safety redundancy for the pneumatic system, immediately preventing the push block 32B from overtraveling in case of abnormal air pressure, thus avoiding breakage of the brittle precious metal wire due to mechanical overload.

[0044] More preferably, the tensioning wheel 31A is made of one or more of the following materials: zirconium oxide, silicon carbide, silicon nitride, polyetheretherketone, polytetrafluoroethylene, polyimide, aluminum alloy, and stainless steel.

[0045] Zirconia, in particular, possesses ultra-high hardness and excellent wear resistance, with a low coefficient of surface friction, significantly reducing frictional damage to precious metal wires. Furthermore, its chemical stability allows it to withstand lubricants and humid environments, making it suitable for the production environment of high-speed embroidery machines. In practical applications, the 31A tensioning wheel made of zirconia can extend the lifespan of metal wires. Silicon carbide and silicon nitride are both high-performance ceramics. With a hardness comparable to zirconium oxide but superior thermal conductivity, silicon nitride can quickly dissipate heat generated by wire friction, preventing the metal wire from softening and deforming due to temperature rise. Silicon nitride has slightly better toughness, making it suitable for handling thick-diameter metal-coated wires, such as gold-plated steel wire. Both perform exceptionally well in the field of smart textiles, ensuring the resistance stability of conductive embroidery threads. Polyetheretherketone (PEEK) is a self-lubricating engineering plastic with a low coefficient of friction, requiring almost no additional lubrication during operation. Its lightweight properties reduce the inertia of the machine head, making it suitable for dynamic tension adjustment systems. PEEK tensioning rollers are particularly compatible with mixed threads, such as metal and synthetic fibers, effectively absorbing vibration noise; however, long-term use requires anti-static treatment. Polytetrafluoroethylene (PTFE), also known as Teflon, has the lowest known coefficient of friction, maximizing the protection of the metal wire surface's luster, but its lower mechanical strength limits its suitability for low-speed, precision embroidery. Polyimide combines high temperature resistance and high strength, making it suitable for precious metal threads requiring heat annealing. Both are often used as coatings in combination. Aluminum alloys are lightweight and easy to process, making them suitable for prototypes or low-cost applications, but they require hard anodizing or DLC coating to improve wear resistance. Stainless steel is highly corrosion-resistant and suitable for humid environments or chemically lubricated applications, but its greater weight may affect high-speed response. In tensioner 31A, both aluminum alloys and stainless steel are typically used as complements to ceramic or plastic materials for high-load, thick-thread embroidery.

[0046] Therefore, by means of a tensioning wheel 31A fixedly connected to the machine head 31, and the thread wound around the tensioning wheel 31A, the tension of the thread on the device 100 can be effectively controlled by the tensioning wheel 31A, avoiding breakage or loosening of the thread due to tension fluctuations during high-speed embroidery. Furthermore, by using the guide groove 31B to enter the embroidery needle 31C along the first direction F1, the thread on the device 100 enters the embroidery needle 31C along a preset path, preventing the thread from slipping off the path and preventing skipped stitches and thread tangling in the embroidery needle 31C.

[0047] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
