Description

Technical Field

[0001] The utility model relates to a special embroidery mechanism and an embroidery machine capable of corresponding to multi-needle position embroidery, belonging to the technical field of embroidery machines. Background Art

[0002] In the technical field of embroidery machines, special embroidery devices are used for special embroidery, such as gold piece devices, cord embroidery devices and other special devices and needle bar racks for special embroidery.

[0003] In the prior art, for special embroidery devices, the needle bar rack is slidably connected to the machine head, and the machine head is fixed on the beam. The crossbar serves as a load-bearing structure for fixing the special embroidery device and is fixedly connected to the beam through connecting parts. Usually, large embroidery machines have more machine heads, which results in a longer crossbar. In order to ensure the structural stability of the crossbar, multiple connecting parts are usually required. The connecting parts are located between adjacent machine heads. When the needle bar rack has a large number of needle positions, the needle bar rack is easily interfered with and collided with the connecting parts when switching needle positions due to the lateral movement of the machine head. Therefore, the limit on the head distance (the distance between the machine heads) is relatively high. Utility Model Content

[0031] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0032] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0033] Implementation Case 1:

[0034] A special embroidery mechanism, used in embroidery machines, can handle multiple needle positions. Figures 1-4The special embroidery mechanism of this embodiment includes a machine head 2, a needle bar frame 3, a crossbar 4, a special embroidery device 5 and a first connecting component 6. The machine head 2 is fixedly connected to the beam 1, which is arranged in the horizontal direction. There are at least two machine heads 2. When there are multiple machine heads 2, multiple machine heads 2 are fixed on the beam 1 at intervals in the horizontal direction. The needle bar frame 3 is located in front of the machine head 2. A guide rail assembly 7 is arranged between the needle bar frame 3 and the machine head 2, so that the needle bar frame 3 can slide in the horizontal direction relative to the machine head 2, so that the needle bar frame 3 can replace the embroidery needle by sliding in the horizontal direction during embroidery, thereby realizing embroidery with multiple needle positions. The crossbar 4 is extended in the horizontal direction and spans at least two of the machine heads 2. The special embroidery device 5 is fixedly connected to the crossbar 4. The first connecting component 6 is fixedly connected to the needle bar frame 3 or / and the guide rail assembly 7, and is slidably connected to the crossbar 4, so that the needle bar frame 3 can slide in the horizontal direction relative to the crossbar 4.

[0035] In this embodiment, the special embroidery device 5 can be configured to perform special embroidery such as tape embroidery and gold plate embroidery, and cooperate with the needle bar frame 3 to perform special embroidery.

[0036] In this embodiment, the first connecting component 6 takes the position as a reference and a carrier, jumps out of the space and is slidably connected to the cross bar 4, so that the lateral sliding of the needle bar frame 3 relative to the cross bar 4 and the lateral sliding of the needle bar frame 3 relative to the machine head 2 remain strictly parallel, which not only makes the mutual coordination actions remain accurate and stable, that is, ensures the high precision of embroidery, but also facilitates the installation of various components of the special embroidery mechanism.

[0037] It should be noted that, due to the long length of the crossbar 4, it is difficult to ensure that each section of the crossbar 4 strictly maintains the lateral directionality. However, in this embodiment, the connection method of the first connecting component 6 can ensure that the lateral sliding of the needle bar frame 3 relative to the crossbar 4 and the lateral sliding of the needle bar frame 3 relative to the machine head 2 remain strictly parallel. In other words, it can ensure that the crossbar 4 and the guide rail assembly 7 remain strictly parallel, so there is no need to set a connecting component between adjacent machine heads 2 to fix the crossbar 4 and the beam 1. This also avoids the situation where the needle bar frame 3 has a large number of needles and interference occurs due to the lateral sliding along the guide rail assembly 7, and there are restrictions on the number of heads 2. In this embodiment, the connection method of the first connecting component 6 can avoid the need to set a connecting component between adjacent machine heads 2, so that the special embroidery mechanism of this embodiment can be suitable for any head distance (the spacing between the machine heads 2), and there is no limit on the number of needle positions of the needle bar frame 3.

[0038] Regarding the connection method of the crossbar 4, in the first embodiment, the special embroidery mechanism further includes at least one second connecting component 8, which is fixedly connected to the beam 1 and the crossbar 4. Generally, one second connecting component 8 is provided at each end of the crossbar 4, which can meet the fixed connection requirements of the crossbar 4 and will not affect the lateral sliding of the needle bar frame 3.

[0039] Regarding the connection method of the crossbar 4, in the second embodiment, this special embroidery mechanism also includes at least one second connecting component 8. This second connecting component 8 is fixedly connected to the main beam 1 and slidably connected to the crossbar 4, allowing the crossbar 4 to slide laterally relative to the main beam 1. Similar to the first embodiment, in general, a second connecting component 8 is provided at each end of the crossbar. This second connecting component 8 can be configured as a color change box or other mechanism.

[0040] Furthermore, in the second embodiment, a locking mechanism (not shown) is provided between the second connecting assembly 8 and the crossbar 4 for locking the crossbar 4 or unlocking the crossbar 4 and allowing it to slide laterally relative to the main beam 1. When the needle bar frame 3 and the special embroidery device 5 cooperate to perform special embroidery, the locking mechanism locks the crossbar 4. Other types of special embroidery devices 5 can also be installed on the crossbar 4. When the special embroidery needs to be changed, the locking mechanism is unlocked, and the crossbar 4 slides laterally, allowing the corresponding special embroidery device 5 to move to a designated position to cooperate with the needle bar frame 3 for embroidery.

[0041] In this embodiment, the crossbar 4 is located in front of the needle bar frame 3, which makes the spatial layout more reasonable.

[0042] In this embodiment, the first connecting assembly 6 includes a fixed member 61 and a sliding carriage 62 connected to each other. The fixed member 61 is fixed to the needle bar frame 3. The crossbar 4 has a slide rail 41 extending in the transverse direction. The sliding carriage 62 is slidably connected to the slide rail 41. The sliding carriage 62 has a plurality of rollers, which can stably and reliably enable the first connecting assembly 6 to slide and connect to the crossbar 4.

[0043] In this embodiment, the slide rail 41 is provided on the side of the crossbar 4 facing the needle bar frame 3 .

[0044] In this embodiment, a mounting member is provided on the side of the crossbar 4 facing away from the needle bar frame 3 to secure the special embroidery device 5. This allows the special embroidery device 5 and the needle bar frame 3 to be spaced a certain distance apart in the front-to-back direction to avoid interference. Furthermore, the first connecting assembly 6 and the special embroidery device 5 are disposed on opposite sides of the crossbar 4, further facilitating spatial layout.

[0045] In this embodiment, the first connecting component 6 is fixedly connected to the guide rail component 7. Since the processing precision of the guide rail component 7 is higher, the guide rail component 7 is used as a fixed connection partner, which can better ensure that the lateral sliding of the needle bar frame 3 relative to the cross bar 4 and the lateral sliding of the needle bar frame 3 relative to the machine head 2 remain strictly parallel. Relatively speaking, the needle bar frame 3 is limited by the processing precision requirement which is lower than that of the guide rail component 7. In comparison, fixedly connecting the first connecting component 6 to the guide rail component 7 is the optimal solution.

[0046] In this embodiment, the special embroidery device 5 is provided with a lifting mechanism (not shown in the figure) for lifting the special embroidery device 5. When the special embroidery device 5 is lowered to the working position, it cooperates with the needle bar frame 3 to perform special embroidery. When the special embroidery device 5 is raised to its original position, the needle bar frame 3 performs flat embroidery alone, making the application range of the special embroidery device wider.

[0047] In this embodiment, a positioning member 31 is provided at the bottom of the needle bar frame 3. This member acts on the special embroidery device 5 to locate the position of the special embroidery device 5. More specifically, in this embodiment, the positioning member 31 is configured as a slot or a clip. When the special embroidery device 5 is lowered to the working position, the special embroidery device 5 and the positioning member 31 engage, thereby positioning the special embroidery mechanism. The provision of the positioning member 31 allows the special embroidery device 5 to be precisely positioned, preventing it from deflecting in the four directions of front, back, left, and right. This ensures the quality and high precision of the embroidery when the special embroidery device 5 and the needle bar frame 3 cooperate to perform special embroidery.

[0048] Implementation Case 2:

[0049] An embroidery machine includes a special embroidery mechanism that can correspond to multi-needle position embroidery, wherein the special embroidery mechanism is as described in Implementation Case 1.

[0050] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
