Technical Field

[0001] The invention belongs to the technical field of embroidery machines, and in particular relates to an easy-to-install guide rail structure applied to embroidery machines. Background Art

[0002] Computer embroidery machines are the most advanced embroidery machines of the time. They can make traditional hand-made embroidery be realized at high speed and high efficiency, and can also achieve the requirements of "multi-level, multi-function, unity and perfection" that hand-made embroidery cannot achieve. They are electromechanical products that embody a variety of high-tech technologies. Computer embroidery machines are often used to sew sequins onto the surface of fabrics to enhance the beauty of the fabrics.

[0003] During the embroidery process, since different positions of the fabric need to be embroidered, the cloth clamping frame needs to move back and forth. Most of the existing technologies use a square guide rail installed inside the embroidery machine body to achieve guidance, but this leads to higher installation accuracy requirements. At the same time, only one guide rail will also lead to instability during the guiding process.

[0004] In response to this problem, people have also conducted exploration and research in long-term production and life practices. For example, a Chinese utility model patent discloses a guide rail structure for an embroidery machine [application number: 201620716828.1]. The utility model patent includes a guide rail and a sleeve sliding on the guide rail. The sleeve is located on both sides of the guide rail and is provided with bearings or bearing groups that match the corresponding sides of the guide rail.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Combination Figure 1 and Figure 4 As shown, an easy-to-install guide rail structure for an embroidery machine includes an embroidery machine body 200, and at least two guide rail mounting plates 8 arranged on the embroidery machine body 200, each guide rail mounting plate 8 also has at least two guide rail mounting holes 9, and a guide rail 10 is connected to the guide rail mounting plate 8 through the guide rail mounting holes 9. The guide rails 10 are provided with at least two and are parallel to each other, and each guide rail 10 is slidably connected to at least one connecting slider 11.

[0033] The structure that needs to be guided by movement, such as the cloth-clamped air frame, is connected to the guide rail 10 by connecting the slider 11, so that the direction of movement of the cloth-clamped air frame is consistent with the extension direction of the guide rail 10. At least two guide rails 10 are provided to ensure the stability of the guiding process, and the guide rail mounting plate 8 is used to realize the installation of the guide rail 10. In this way, by controlling the position of the guide rail mounting hole 9 processed on the guide rail mounting plate 8, the parallel installation of the guide rail 10 can be ensured, that is, the machining accuracy of the guide rail mounting hole 9 replaces the installation accuracy of the guide rail mounting plate 8, reducing the difficulty of installation. At present, the machining accuracy of the mechanical processing can achieve the accuracy of 1 thread, so that the machining accuracy required for the guide rail mounting hole 9 can be easily achieved using existing processing machines.

[0034] Specifically, two guide rail mounting plates 8 are provided and are respectively connected to the two ends of the embroidery machine body 200. Each guide rail mounting plate 8 has two guide rail mounting holes 9, and the distance between the two guide rail mounting holes 9 on each guide rail mounting plate 8 is equal. By ensuring that the distance between the two guide rail mounting holes 9 on each guide rail mounting plate 8 is equal, the two guide rails 10 after installation are ensured to be parallel to each other.

[0035] Preferably, the guide rail mounting hole 9 is a through hole that penetrates the guide rail mounting plate 8. The through hole structure facilitates the installation of the guide rail 10.

[0036] Preferably, the cross-sectional area of ​​the guide rail 10 is circular, and the guide rail 10 is located outside the embroidery machine body 200. The guide rail 10 is installed on the outer side of the embroidery machine body 200. The square guide rail of the prior art is installed inside the embroidery machine body 200, or the overall structure of the embroidery machine body 200 accommodates the square guide rail. The reason is that the installation of the square guide rail needs to be fixed in more than one direction in the direction of the square cross section; after replacing it with a circular guide rail, the installation accuracy can be reduced, and it does not need to be fixed in multiple directions of the circular interface. Therefore, the present invention installs the guide rail 10 on the outer side of the embroidery machine body 200, which further reduces the installation difficulty compared to the method of installing it inside the embroidery machine body 200 in the prior art.

[0037] Combination Figure 4 and Figure 5 As shown, at least one support block 12 is connected to the guide rail 10, and one end of the support block 12 away from the guide rail 10 is fixedly connected to the embroidery machine body 200. The guide rail 10 is generally made of metal material, which has elasticity. Therefore, when the guide rail 10 is long, the guide rail 10 will bend slightly, especially in the middle position, resulting in reduced guiding accuracy. Therefore, a support block 12 is provided to support the guide rail 10 to offset the bending.

[0038] Preferably, each guide rail 10 is connected to a support block 12, and the distance between the support block 12 and the two guide rail mounting plates 8 is equal. According to the length of the currently commonly used guide rails 10, a support block 12 is provided and placed in the middle position to prevent the guide rail 10 from bending.

[0039] like Figure 5 As shown, the support block 12 includes an integrally formed mounting portion 121 and a connecting portion 122, wherein the mounting portion 121 is fixedly connected to the embroidery machine body 200, and one end of the connecting portion 122 away from the mounting portion 121 is connected to the guide rail 10, and the cross-sectional area of ​​the mounting portion 121 is greater than the cross-sectional area of ​​the connecting portion 122.

[0040] Preferably, a side of the connecting slider 11 close to the connecting portion 122 is further provided with an escape space 13 recessed into the connecting slider 11, and the connecting slider 11 can slide so that the connecting portion 122 passes through the escape space 13, and the width of the connecting portion 122 close to the mounting portion 121 is greater than the width of the connecting portion 122 close to the guide rail 10. In this way, the connecting slider 11 can smoothly slide over the mounting position of the support block 12 on the guide rail 10 to avoid interference.

[0041] Combination Figure 1 and Figure 2As shown, the embroidery machine body 200 is also provided with a wire drum 1 for placing the thread ball 100, and the wire drum 1 is connected to a wire passing plate 2, and the wire passing plate 2 is provided with a plurality of mutually independent wire passing structures 3, and the wire drum 1 is also provided with a lead assembly frame 4, and the wire passing plate 2 is fixedly connected to one end of the lead assembly frame 4, and the lead assembly frame 4 is provided with a plurality of lead structures 5 and a conductor structure 6. When in use, the embroidery machine thread passes through the conductor structure 6, the lead structure 5 and the wire passing structure 3 in sequence; or the embroidery machine thread passes through the conductor structure 6 and the wire passing structure 3 in sequence; or the embroidery machine thread passes through the lead structure 5 and the wire passing structure 3 in sequence.

[0042] That is, the thread on the thread ball 100 will at least be guided by the lead structure 5 or the conductor structure 6 before reaching the thread passing structure 3 during the embroidery process. Therefore, the embroidery machine thread of the present invention will at least be guided by the lead structure 5 and the conductor structure 6 before reaching the thread passing structure 3, thereby ensuring the regularity of the embroidery machine thread and preventing the occurrence of the problem of winding thread.

[0043] Combination Figure 2 and Figure 3 As shown, the lead assembly frame 4 includes at least one first support frame 41 fixedly connected to the wire drum 1, the wire structure 6 is arranged on the first support frame 41 and passes through the first support frame 41, the first support frame 41 is connected to a lead frame 42, and the lead structure 5 is arranged on the lead frame 42. Multiple first support frames 41 can be provided, for example, two parallel to each other.

[0044] Preferably, the length direction of the lead frame 42 is parallel to the length direction of the wire passing plate 2, and a plurality of lead structures 5 are provided and arranged in sequence along the length direction of the lead frame 42, so that the wire guided by the lead structure 5 can pass through the wire passing groove 31 more conveniently.

[0045] The lead structure 5 includes a lead hook 51 fixedly connected to the lead frame 42 and / or a lead through hole 52 penetrating the lead frame 42, and a porcelain sleeve 7 is sleeved in the lead through hole 52. That is, the lead structure 5 can be a lead hook 51 or a lead through hole 52, or other specific structures in the prior art that can guide the wire. Sleeving the porcelain sleeve 7 in the lead through hole 52 can reduce the friction force on the wire during the embroidery process and prevent the problem of wire breakage.

[0046] like Figure 2As shown, the wire structures 6 are provided in a plurality and are arranged in sequence along the length direction of the first support frame 41. The wire structures 6 include a wire through hole 61 penetrating the first support frame 41. The wire through hole 61 is sleeved with a porcelain sleeve 7. The porcelain sleeve 7 sleeved in the wire through hole 61 can reduce the friction force on the thread during embroidery and prevent the problem of thread breakage. The length direction of the first support frame 41 is perpendicular to the length direction of the wire plate 2, that is, the first support frame 41 extends in the longitudinal direction. The wire structures 6 of the present invention are all arranged in sequence along the length direction of the first support frame 41. The arrangement of the wire structures 6 controls the direction of the line, so that the thread balls can be arranged roughly in a straight line, which is compact and saves space, and further prevents winding.

[0047] Combination Figure 2 and Figure 3 As shown, the lead assembly frame 4 also includes at least one second support frame 43, one end of the second support frame 43 is fixedly connected to the bottom surface of the first support frame 41, and the other end is fixedly connected to the wire drum 1. The second support frame 43 is arranged to support the first support frame 41, and the first support frame 41 and the second support frame 43 cooperate with each other to form a more stable support.

[0048] Preferably, the second support frame 43 and the first support frame 41 are both formed by bending metal bars, for example, they can be formed by bending iron bars. The first support frame 41 and the second support frame 43 are both formed by bending metal bars, which can have lower weight and cost compared to using columns as supports. And the bending direction of the end of the second support frame 43 is perpendicular to the bending direction of the end of the first support frame 41. That is, the pointing direction of the end of the first support frame 41 is perpendicular to the pointing direction of the end of the second support frame 43, so the bending direction of the end of the second support frame 43 is perpendicular to the bending direction of the end of the first support frame 41, which can prevent overall shaking in both the horizontal and vertical directions.

[0049] like Figure 3 As shown, the wire passing structure 3 includes a wire passing groove 31 disposed on the upper surface of the wire passing plate 2 and recessed into the wire passing plate 2 and / or a wire passing through hole penetrating the wire passing plate 2. Each wire passes through a corresponding wire passing groove 31 or a wire passing through hole.

[0050] Preferably, the distances between two adjacent thread grooves 31 are equal. This allows the embroidery machine threads, especially those near the thread grooves 31, to be roughly spaced apart, further preventing the problem of thread winding.

[0051] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
