Description

Technical Field

[0001] This application relates to the field of fabric clip technology, and more specifically, to an airbag-type automatic fabric clip. Background Technology

[0002] Fabric clips are a key component of embroidery machines, mainly used to fix and stabilize the fabric during the embroidery process, ensuring the accuracy and efficiency of the embroidery.

[0003] Traditional fabric clamps are usually clamped and removed manually, which not only requires a long operation time, but also relies heavily on the operator's experience. Fluctuations in clamping pressure may cause defects in the embroidery, so manual calibration is required repeatedly, resulting in extremely high labor costs. It is only suitable for low-volume, multi-variety, and frequent fabric changes. Summary of the Invention

[0004] To address the aforementioned technical problems, this application is proposed. The advantage of this application lies in providing an airbag-type automatic fabric clamp. When the airbag is depressurized, the arc-shaped flanges on the two clamping arms hold and fix the fabric. When the airbag inflates, the driving component is activated, thereby opening the two clamping arms. At this time, the arc-shaped flanges of the clamping arms release the fabric. This effectively improves the efficiency and accuracy of fabric fixing and reduces manual labor intensity. Furthermore, the first and second driving arms of the driving component are hinged, making the control of the clamping arms more flexible and stable.

[0005] To achieve at least one of the above advantages, this application provides an airbag-type automatic fabric clamp, including a fabric clamp body, the fabric clamp body including two clamping arms and a connector connecting the two clamping arms; a driving member, the driving member being disposed within the fabric clamp body and forming an airbag mounting cavity with the fabric clamp body, the driving member including a first driving arm and a second driving arm, the first driving arm and the second driving arm being movably hinged, the ends of the first driving arm and the second driving arm being respectively engaged with the two clamping arms; and an airbag, the airbag being disposed within the airbag mounting cavity.

Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] In the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0024] like Figures 1-2 As shown, the structure of the airbag-type automatic fabric clamp according to Embodiment 1 of this application is illustrated. It includes a fabric clamp body 1, a driving member 2, and an airbag 3. The fabric clamp body 1 includes two clamping arms 11 and a connecting member 12 connecting the two clamping arms 11. The driving member 2 is disposed within the fabric clamp body 1 and forms an airbag mounting cavity 4 with the fabric clamp body 1. The driving member 2 includes a first driving arm 21 and a second driving arm 22. The first driving arm 21 and the second driving arm 22 are movably hinged, and the ends of the first driving arm 21 and the second driving arm 22 are respectively engaged with the two clamping arms 11. The airbag 3 is disposed within the airbag mounting cavity 4.

[0025] In other words, when the airbag 3 is in a depressurized state, the arc-shaped flanges 112 on the two clamping arms 11 clamp and fix the fabric. When the airbag 3 is inflated, the first driving arm 21 and the second driving arm 22 rotate under the squeezing action of the airbag 3, thereby opening the clamping arms 11. Furthermore, the hinged connection makes the control of the clamping arms 11 by the airbag 3 during inflation and deflation more flexible and stable.

[0026] Specifically, the airbag mounting cavity 4 includes a first mounting cavity 41 and a second mounting cavity 42. The driving member 2 includes a hinge portion 23 and an extension portion 24. The first mounting cavity 41 is formed between the hinge portion 23 and the connecting member 12, and the second mounting cavity 42 is formed between the extension portion 24 and the clamping arm 11. Preferably, the hinge portion 23 extends downward at an angle from the middle, that is, when the airbag 3 is inflated, the top of the hinge portion 23 abuts against the airbag 3, thereby causing the first driving arm 21 and the second driving arm 22 to be squeezed and rotated.

[0027] More specifically, the airbag 3 includes an airbag portion 31 and support portions 32 disposed at both ends of the airbag portion 31. The airbag portion 31 is disposed within the first mounting cavity 41, and the support portions 32 are disposed within the second mounting cavity 42. It should be understood that the airbag portion 31 can be inflated or deflated. The support portions 32 not only seal the airbag portion 31 but also support it between the clamping arm 11 and the extension portion 24 to ensure the stability of the movement of the drive member 2.

[0028] In particular, such as Figure 3 and Figure 4 As shown, one end of the first drive arm 21 is provided with a plurality of first hinge members 211, and one end of the second drive arm 22 is provided with a plurality of second hinge members 221. The first hinge members 211 and the second hinge members 221 are interlocked and connected through a spindle 25.

[0029] Furthermore, the first hinge member 211 is provided with a first limiting block 212, which abuts against the lower part of the second driving arm 22. Similarly, the second hinge member 221 is provided with a second limiting block 222, which abuts against the lower part of the first driving arm 21. It should be understood that the first limiting block 212 and the second limiting block 222 effectively control the minimum clamping distance between the two clamping arms 11.

[0030] Furthermore, the other ends of the first drive arm 21 and the second drive arm 22 are provided with a plurality of engaging blocks 26, and the two clamping arms 11 are provided with a plurality of slots 111, into which the engaging blocks 26 engage. In this way, the first drive arm 21 and the second drive arm 22 are engaged with the two clamping arms 11 respectively, thereby realizing the linkage between the drive component 2 and the clamping arms 11, and further improving the stability of the linkage.

[0031] Preferably, both clamping arms 11 have inwardly bent arc-shaped flanges 112 at their ends. This design effectively prevents the ends of the clamping arms 11 from scratching the fabric.

[0032] Preferably, the two clamping arms 11 and the connecting member 12 are integrally bent and formed, which makes it easier to manufacture and process the main body of the cloth clamp.

[0033] In summary, this application provides an airbag-type automatic fabric clamp. When the airbag 3 is in a depressurized state, the arc-shaped flanges 112 on the two clamping arms 11 clamp and fix the fabric. When the airbag 3 is inflated, the driving member 2 is driven, thereby opening the two clamping arms 11. At this time, the arc-shaped flanges 112 of the clamping arms 11 release the fabric. In this way, the efficiency and accuracy of fabric fixing are effectively improved, and the intensity of manual labor is reduced. In addition, the first driving arm 21 and the second driving arm 22 of the driving member 2 are movably connected by a hinge, making the control of the clamping arms 11 more flexible and stable.

[0034] The basic principles of this application have been described above with reference to specific embodiments. However, it should be noted that the advantages, benefits, and effects mentioned in this application are merely examples and not limitations, and should not be considered as essential features of each embodiment of this application. Furthermore, the specific details disclosed above are for illustrative and facilitative purposes only, and are not limitations.
