Technical Field
[0001] This invention relates to the field of computer embroidery machine technology, and in particular to a single-needle multi-color wool embroidery device. Background Technology
[0002] With the diversification of embroidery products and the rapid changes in demand in the embroidery market, continuous improvement of computer embroidery technology and embroidery institutions has been driven.
[0003] Currently, wool embroidery is a relatively new embroidery technique on computerized embroidery machines. Utilizing the inherent plasticity of pure wool yarn, it creates fluffy, three-dimensional patterns. Combined with the interweaving of multiple colors and its integration with multi-colored flat embroidery, it can produce vibrant, multi-layered, three-dimensional embroidery pieces, receiving widespread market acclaim. However, in production, compared to flat embroidery, wool embroidery generally suffers from lower production efficiency, a more limited range of embroidery methods, and the use of flat embroidery resources for each stitch. The root causes are: 1. Some wool embroidery machines cannot automatically adjust the height of the yarn guide, preventing the stacking of yarn with varying degrees of fluffiness and making it difficult to create a three-dimensional effect with varying heights; 2. The combination of wool embroidery and flat embroidery generally uses a richer range of colors. The one-stitch-one-color transmission structure of some wool embroidery machines causes the flat embroidery needle bar resources to be occupied by wool embroidery, reducing the colors available for flat embroidery (only one can be chosen for each stitch), resulting in a limited color range in combined embroidery pieces. Summary of the Invention
[0004] To address the problems existing in the prior art, a single-needle multi-color yarn embroidery device is provided, which can stack yarns of different colors and fluffiness under the same needle, enabling continuous, fast and efficient embroidery production of three-dimensional patterns with single needle, multiple colors and fluffiness.

[0030] like Figure 1 As shown, a single-needle multi-color yarn embroidery device is installed on the flat embroidery head 20 of a computerized embroidery machine. The flat embroidery head 20 is equipped with a drive mechanism and a needle bar frame 30 connected to it. The needle bar frame 30 is equipped with a row of needles 40. Each needle 40 can independently reciprocate along the Z direction under the drive of the drive mechanism to drive a yarn 50 through the fabric on the embroidery frame below. The single-needle multi-color yarn embroidery device includes a thread guide module 60, a guide nozzle drive module 70, and a color changing module 80, wherein:
[0031] like Figure 2-3 As shown, the thread guide module 60 includes a mounting plate 1 hinged to the needle bar frame 30. The mounting plate 1 is provided with a horizontal slide rail 2. A guide nozzle frame 3 is mounted on the slide rail 2. Several push rods 4 extending along the Z direction are movably mounted on the guide nozzle frame 3. Each push rod 4 has an inclined guide nozzle 5 at its end. The end of a guide nozzle 5 extends to the bottom of the head or end of a row of needles 40. Each guide nozzle 5 is connected to a thread guide tube 6. A yarn 50 is threaded through each thread guide tube 6. Several thread guide tubes 6 are mounted above the mounting plate 1 through a first thread guide frame 7.
[0032] like Figure 4 As shown, the drive module 70 includes a first plate 101 mounted on the mounting plate 1. The first plate 101 is provided with a first drive device 8. The first drive device 8 is connected to a push plate 10 via a first transmission device 9. The push plate 10 is sleeved on a positioning post 11 extending in the Z direction. The push plate 10 is provided with a first synchronization element 1001 adapted to each push rod 4. The first drive device 8 can drive the push plate 10 to slide on the positioning post 11, so as to drive a push rod 4 to move in the Z direction and simultaneously drive a guide nozzle 5 at its end to move in the Z direction.
[0033] like Figure 5 As shown, the color-changing module 80 includes a second drive device 12 mounted on the mounting plate 1. The second drive device 12 is connected to the guide nozzle frame 3 via a second transmission device 13. The guide nozzle frame 3 can slide on the slide rail 2 under the drive of the second drive device 12, thereby driving a number of guide nozzles 5 on it to move horizontally.
[0034] This invention, by setting a drive module 70, allows each guide nozzle 5 to move individually toward the fabric via a first drive device 8, carrying a yarn 40 of a specific color. The movement distance (height) of the guide nozzle 5 can be adjusted to achieve the desired fluffiness by stacking the yarn of that color on the fabric. By setting a color-changing module 80, a second drive device 12 can drive the guide nozzle frame 3 to move horizontally, thereby moving the guide nozzle 5 and placing the corresponding color yarn below the needle 40. This, combined with the horizontal movement of the fabric (embroidery frame), allows the needle 40 to... The up-and-down reciprocating motion and the drive module control the up-and-down movement of the guide nozzle 5, which can stack yarns of different colors and fluffiness on the fabric, and realize continuous, fast and efficient embroidery production of three-dimensional patterns with single needle, multiple colors and multiple fluffiness. The yarn embroidery device has a simple overall structure. It only needs to be hinged to the mounting plate 1 at an appropriate position next to the head of a regular flat embroidery machine, and with the thread guide module 60, the conventional flat embroidery equipment can be converted into yarn embroidery equipment. The conversion cost is low, the assembly is convenient, and it is suitable for most computer embroidery machines.
[0035] like Figure 4As shown, in some embodiments of the present invention, the first driving device 8 is a motor; the first transmission device 9 includes a first rod 901 and a second rod 902 that are hinged together. The first rod 901 is connected to the first driving device 8 and can rotate under its drive. The second rod 902 is hinged to the push plate 4.
[0036] like Figure 5 As shown, in some embodiments of the present invention, the second drive device 12 is a motor; the second transmission device 13 includes two gear shafts 131 and a synchronous belt 132 sleeved on the two gears. One gear shaft 131 is connected to the second drive device 12 and can rotate under its drive. The synchronous belt 132 is provided with a second synchronizing element 133, and the second synchronizing element 133 is detachably fixed to the guide nozzle 5.
[0037] like Figure 5 As shown, in some embodiments of the present invention, each guide nozzle 5 includes a guide plate 501 extending obliquely downward toward the needle 40. Each guide plate 501 is provided with a guide ring 502 and one or more guide hole grooves 503. Each guide ring 502 is located at the end of the guide plate 501 and can accommodate a needle 40 and a thread 50 through it. Each guide hole groove 503 can accommodate a thread 50 through it.
[0038] Understandably, the guide slot 503 and guide ring 502 are designed to further straighten each strand of yarn, preventing the yarn from shifting and causing pulling or tangling when the needle 40 pierces the guide ring 502. At the same time, they can prevent the yarn from remaining smooth as it passes through the guide ring 502 when the end of the yarn is cut, making it easier to guide and pierce the yarn of the same color again in the future.
[0039] like Figure 6-7 As shown, in some embodiments of the present invention, each push rod 4 is detachably fixed with a radially extending protrusion 401, and each push rod 4 is provided with a return spring 402 on one side of the protrusion 401; the first synchronizing member 1001 is a slot adapted to the protrusion 401.
[0040] During operation, the first drive device 8 drives the first rod 902 to rotate, pulling one end of the second rod 902 to swing synchronously, thereby pulling the push plate 10 to slide downward on the positioning post 11. The push plate 10 pushes the protrusion 401 on a push rod 4 to slide synchronously, causing the push rod 4 to move downward and compress the return spring 402, sending the guide nozzle 5 at its lower end to an appropriate height below the needle 40. In conjunction with the up and down movement of the needle 40, the embroidery action of the yarn of that color is completed. When it is necessary to change colors, the thread cutting mechanism on the embroidery machine cuts the yarn on the fabric. The first drive device 8 drives the push plate 10 to move upward and reset, and the second drive device 12 drives the guide nozzle frame 3 to move horizontally, sending the protrusion 401 on another push rod 4 into the slot of the push plate 10. By repeating the above actions, continuous yarn changing and automatic control of the stacking effect of each color of yarn can be completed.
[0041] Understandably, the setting of the return spring 402 on the push rod 4 facilitates the push rod 4 to move upward and reset quickly, increases the thread changing frequency, meets the needs of high-speed operation of the embroidery machine, and at the same time reduces the load on the first drive device 8 and extends its working life.
[0042] like Figure 2 As shown, in some embodiments of the present invention, the mounting plate 1 is further provided with a second plate 102, and the slide rail 2, the first plate 101 and the positioning post 11 can all be detachably fixed on the second plate 102.
[0043] In this embodiment, the second plate 102 is detachably fixed on the mounting plate 1, and the first plate 101, the slide rail 2 and the positioning column 11 are all detachably fixed on the second plate 102. This facilitates the installation and fixing of the drive module 70 and the color-changing module 80, effectively utilizes space, reduces the overall space occupied by the device, and facilitates the formation of functional modules for application on different embroidery machines. Installation is convenient and quick.
[0044] In some embodiments of the present invention, the end of the guide nozzle frame 3 is further provided with a second wire guide frame 301, and one end of each wire guide tube 6 is mounted on the second wire guide frame 301.
[0045] In some embodiments of the present invention, the first cable guide 7 and the second cable guide 301 are provided with a plurality of through holes, each through hole is fitted with a cable guide sleeve 14, and each cable guide sleeve 14 is fitted with a cable guide tube 6.
[0046] In this embodiment, the first thread guide 7 is fixed above the mounting plate 1 by a support pillar. By rotating the mounting plate 1, the relative positions of the first thread guide 7 and the second thread guide 301 with the main structure of the embroidery machine can be adjusted simultaneously, which facilitates the straightening of the yarn and makes it easier for the needle 40 to smoothly insert the yarn into the fabric.
[0047] like Figure 1 As shown in some embodiments of the present invention, a control module 90 is also included. The control module 90 includes a control box 91, on which a control board 92 and a function board are mounted. The control board 92 is electrically connected to the function board, the main control signal board of the computer embroidery machine, the first drive device 8, and the second drive device 12.
[0048] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the technical scope of the present invention.
