[0002] As an automated embroidery device, the color-changing mechanism of an embroidery machine is a core component for achieving multi-color embroidery. This mechanism drives the needle bar frame to move, switching the needles of different colors to their working positions, thus automating the multi-color embroidery process. The stability, precision, and response speed of the color-changing mechanism directly affect the embroidery efficiency and finished product quality of the embroidery machine.

[0003] Currently, most existing embroidery machine color-changing mechanisms use a combination of guide rails and sliders to achieve the translational movement of the needle bar frame. This type of structure typically includes complex guiding components and numerous connecting parts, requiring high assembly precision and a cumbersome installation process. Furthermore, the guide rail and slider structure is prone to wear during long-term use, necessitating regular maintenance and lubrication, increasing operating costs and downtime. In addition, this structure demands high precision in frame machining and assembly processes, further increasing the difficulty of manufacturing and maintenance. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a color-changing mechanism for an embroidery machine, which can effectively solve the technical problem of complex translation structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A color-changing mechanism for an embroidery machine includes a needle bar frame, a power component, and an embroidery machine frame for mounting the needle bar frame and the power component.

[0007] The sliding assembly includes a linear bearing housing and a sliding shaft. The needle bar frame has symmetrical support feet at both ends. The two ends of the sliding shaft are fixedly connected to the two needle bar frames respectively. The linear bearing housing is fixedly installed on the embroidery machine frame near the needle bar frame. The middle section of the sliding shaft passes through the linear bearing housing.

[0008] Furthermore, the surface of the support leg is provided with a "U"-shaped positioning groove, the bottom diameter of which matches the diameter of the sliding shaft, and both ends of the sliding shaft are fixed in the positioning groove by bolts.

[0009] Furthermore, the power assembly includes a drive motor, a color-changing wheel, and a mounting base plate. The drive motor and the color-changing wheel are disposed in the mounting base plate. The drive motor is connected to the color-changing wheel via transmission. A plurality of drive columns are arranged at equal intervals on the surface of the needle bar frame. The surface of the color-changing wheel is provided with a spiral drive groove that cooperates with the drive columns. When the color-changing wheel rotates, the inner wall of the drive groove drives the drive columns to move.

[0010] Furthermore, the output end of the drive motor is provided with an output gear, the color-changing wheel is coaxially provided with an input gear, and a reduction gear meshes between the output gear and the input gear.

[0011] Furthermore, the side wall of the reduction wheel is coaxially provided with a first reduction tooth and a second reduction tooth, the first reduction tooth meshing with the output gear and the second reduction tooth meshing with the input gear.

[0012] Furthermore, a sensor is provided on the mounting base plate, and a detection disc is coaxially connected to the color-changing wheel. The edge of the detection disc is provided with a positioning opening.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is combined with Figures 1-7 A detailed description of a color-changing mechanism for an embroidery machine according to this utility model is provided below:

[0024] A color-changing mechanism for an embroidery machine includes a needle bar frame 1, a power assembly 2, and an embroidery machine frame 3 for mounting the needle bar frame 1 and the power assembly 2. The needle bar frame 1 and the embroidery machine frame 3 are connected by a sliding assembly 4. The needle bar frame 1 can move horizontally relative to the embroidery machine frame 3 along the sliding assembly 4. The power assembly 2 is driven to drive the needle bar frame 1 to achieve translation.

[0025] The sliding assembly 4 includes a linear bearing seat 402 and a sliding shaft 401. The needle bar frame 1 has symmetrical support feet 101 at both ends. The two ends of the sliding shaft 401 are fixedly connected to the two needle bar frames respectively. The linear bearing seat 402 is fixedly installed on the end of the embroidery machine frame 3 near the needle bar frame 1. The middle section of the sliding shaft 401 passes through the linear bearing seat 402.

[0026] By employing a sliding assembly 4 structure that combines a linear bearing housing 402 with a sliding shaft 401, the translational guiding part of the color-changing mechanism is effectively simplified. This structure features fewer parts, simpler assembly, and lower installation precision requirements, significantly reducing manufacturing and maintenance costs. Simultaneously, the linear bearing possesses excellent self-lubricating properties and wear resistance, extending the service life of the mechanism and improving the overall stability and reliability of the embroidery machine.

[0027] The support leg 101 has a U-shaped positioning groove 111 on its surface. The bottom diameter of the positioning groove 111 matches the diameter of the sliding shaft 401. Both ends of the sliding shaft 401 are fixed in the positioning groove 111 with bolts. This makes the connection and installation of the sliding shaft 401 and the needle bar frame 1 simpler and faster. During installation, the sliding shaft 401 is simply placed into the U-shaped groove for initial positioning and support, without the need for additional clamps. Finally, it is fixed by tightening the bolts, which greatly improves assembly efficiency and reduces the difficulty of subsequent maintenance and disassembly.

[0028] The power assembly 2 includes a drive motor 201, a color-changing wheel 202, and a mounting base 203. The drive motor 201 and the color-changing wheel 202 are housed in the mounting base 203. The drive motor 201 is connected to the color-changing wheel 202 via a transmission connection. A plurality of drive columns 102 are equidistantly arranged on the surface of the needle bar frame 1. The surface of the color-changing wheel 202 has a spiral drive groove 212 that mates with the drive columns 102. When the color-changing wheel 202 rotates, the inner wall of the drive groove 212 drives the drive columns 102 to move. This precisely converts the rotational motion of the color-changing wheel 202 into the linear translational motion of the needle bar frame 1. The structure is compact and efficient, and the power transmission is smooth and reliable, ensuring the accuracy and consistency of the color-changing action and contributing to improved quality of embroidery products.

[0029] The output end of the drive motor 201 is equipped with an output gear 204, and the color-changing wheel 202 is coaxially equipped with an input gear 205. A reduction gear 206 meshes between the output gear 204 and the input gear 205. The side wall of the reduction gear 206 is coaxially equipped with a first reduction tooth 216 and a second reduction tooth 226. The first reduction tooth 216 meshes with the output gear 204, and the second reduction tooth 226 meshes with the input gear 205. This design is compact, saves installation space, reduces the number of parts, improves the smoothness of transmission and ease of assembly, enhances the rigidity and reliability of the entire power assembly 2, and effectively increases the torque transmitted from the drive motor 201 to the color-changing wheel 202, ensuring that the color-changing wheel 202 has sufficient power to drive the needle bar holder 1 to move smoothly, preventing jamming or step loss. The reduction structure allows the use of a higher-speed ordinary motor, reducing manufacturing costs and operating noise.

[0030] A sensor 207 is installed on the mounting base plate 203, and a detection disk 208 is coaxially connected to the color-changing wheel 202. The edge of the detection disk 208 has a positioning opening 218. This allows for real-time detection and feedback of the rotational position of the color-changing wheel 202, thereby achieving precise electronic control of the color-changing position of the needle bar frame 1. This avoids the cumulative errors that may exist in traditional mechanical methods, greatly improving the accuracy and automation of the color-changing action, and providing a foundation for the intelligent control of the embroidery machine.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
