Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a tape embroidery mechanism and a mixed embroidery device. Background Technology

[0002] In mixed embroidery devices with ribbon embroidery, the ribbon embroidery machine heads are typically arranged alternately with another type of embroidery machine head. For example, ribbon embroidery and flat embroidery are arranged alternately on a main beam. The machine heads on the same main beam are usually mounted on the same main shaft. The rotation of the main shaft drives all the machine heads. The ribbon embroidery machine head has a thread-taking mechanism, which includes a thread-taking lever and a drive arm that drives the thread-taking lever to take the thread. The drive arm is located on the main shaft, and its corresponding part cooperates with the thread-taking lever to drive the thread-taking lever to move up and down. However, in mixed embroidery, the ribbon embroidery machine head and another type of embroidery machine head usually work alternately. When the other embroidery machine head is working, the main shaft will also rotate. At this time, the drive arm will also drive the thread-taking lever to take the thread, increasing the load on the motor main shaft. In addition, the top thread may be accidentally pulled out from the needle during the thread-taking process, causing the top thread to fall off. Utility Model Content

Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] refer to Figure 1-5 A ribbon embroidery mechanism includes a main shaft 1 and a ribbon embroidery head 2 mounted on the main shaft 1. The ribbon embroidery head 2 includes a thread take-up drive structure 3 mounted on the main shaft 1 and a thread take-up rod assembly 4 that cooperates with the thread take-up drive arm 302 of the thread take-up drive structure 3. The thread take-up rod assembly 4 is slidably mounted on the housing 5 of the head via a mounting shaft 6. The housing 5 is also provided with a drive structure 7 that drives the mounting shaft 6 to slide, thereby causing the thread take-up rod assembly 4 to engage or disengage from the thread take-up drive arm 301.

[0018] The thread-lifting rod assembly 4 includes a drive block 401 that cooperates with the thread-lifting drive arm and a thread-lifting rod 402 that is adjustable on the drive block 401. The angle of the thread-lifting rod 402 is adjustable on the drive block 401 and can be adjusted according to actual needs.

[0019] The described thread-picking drive structure 3 includes a drive cam 301 mounted on the main shaft 1, a thread-picking drive arm 302, and a thread-picking transmission arm 303 located between the drive cam 301 and the thread-picking drive arm 302. The rotation of the main shaft 1 drives the drive cam 301 to rotate, and the thread-picking drive arm 302 is driven to move through the transmission of the thread-picking transmission arm 303.

[0020] A drive assembly 8 is provided between the drive block 401 and the line-taking drive arm 302. The drive assembly 8 includes a fork 801 and a convex shaft 802 that cooperate with each other. In this embodiment, the fork 801 is disposed on the drive block 401, and the convex shaft 802 is disposed on the line-taking drive arm 302; of course, the fork 801 can also be disposed on the line-taking drive arm 302, and the convex shaft 802 can be disposed on the drive block 401.

[0021] The drive structure 7 includes a drive motor 701, a dial ring 703 connected to the line take-up rod assembly 4, and a dial shaft 704 that cooperates with the dial ring 703. The dial shaft 704 is mounted on a connecting rod 702, which can be directly mounted on the output shaft of the drive motor 701 or connected to the drive motor 701 via a transmission rod 705. The drive motor 701 is mounted on a motor mounting bracket 13, which is mounted on the housing 5. The drive motor 701 directly drives the connecting rod 702 to swing, or drives the connecting rod 702 to swing via the transmission rod 705. Since the dial shaft 704 and the dial ring 703 cooperate with each other, the swinging of the dial shaft 704 can drive the dial ring 703 to slide. In this embodiment, the dial shaft 704 is a round shaft mounted on the connecting rod, and the dial ring 703 has a groove that cooperates with the round shaft. However, the structure of the dial shaft 704 and the dial ring 703 is not limited to this; it is only necessary to ensure that the dial shaft can drive the dial ring to slide.

[0022] The take-up lever assembly 4 can be fixedly connected to the dial ring 703 and slide or rotate simultaneously with the dial ring 703. In this case, the dial ring 703 needs to rotate relative to the dial shaft 704 without disengaging from the dial shaft 704, such as the structure described in this embodiment; or the take-up lever assembly 4 can be rotatably connected to the dial ring 703 and can slide with the dial ring 703, but can rotate independently relative to the dial ring 703 to take up the line. In this case, the dial ring 703 and the dial shaft 704 do not need to rotate relative to each other and can be directly connected.

[0023] In one embodiment, the thread take-up lever assembly 4 and the dial ring 703 are slidably mounted on the mounting shaft 6, and the thread take-up lever assembly 4 and the dial ring 703 are rotatably mounted on the mounting shaft 6. The position of the dial ring 703 is controlled by adjusting the drive motor. When the ribbon embroidery mechanism needs to take up the thread, the drive motor drives the dial ring 703 to slide, causing the thread take-up lever assembly 4 to stop in the working position. The thread take-up lever assembly 4 cooperates with the thread take-up drive arm 302 to realize the thread take-up action. When the ribbon embroidery mechanism does not need to take up the thread, the drive motor drives the dial ring 703 to slide, causing the thread take-up lever assembly 4 to stop in the non-working position. The thread take-up lever assembly 4 disengages from the thread take-up drive arm 302, and at this time, the thread take-up lever assembly does not perform the thread take-up action.

[0024] In another embodiment, the thread take-up lever assembly 4 and the dial ring 703 are fixedly mounted on the mounting shaft 6, which is slidable and rotatable on the housing 5. When the drive motor 703 drives the dial ring 703 to slide, it will drive the mounting shaft 6 to slide. One end of the mounting shaft 6 is provided with a retaining ring 11, and a return spring 12 is provided between the retaining ring and the housing 5 to drive the thread take-up lever assembly 4 to return to the non-working position. When the drive motor 701 drives the dial ring 703 to slide, the mounting shaft 6 slides together with the dial ring 703. When the thread take-up lever assembly 4 needs to take up thread, the mounting shaft slides with the dial ring 703 and simultaneously drives the thread take-up lever assembly 4 into the working position. When the thread take-up lever assembly 4 rotates, the mounting shaft rotates synchronously. At this time, the return spring 12 is in a compressed state. When the thread take-up lever assembly 4 does not need to take up thread, the mounting shaft slides with the dial ring 703, and under the elastic action of the return spring 12, the thread take-up lever assembly 4 enters the non-working position.

[0025] Preferably, the housing 5 is further provided with a limiting structure 9 to restrict the rotation of the drive block 401. The thread take-up lever assembly 4 engages with the limiting structure 9 when it is in the non-working position. The limiting structure 9 is a limiting protrusion, and the drive block 401 is provided with a groove 10 that engages with the limiting protrusion. The limiting structure 9 is provided to restrict the rotation of the thread take-up lever assembly 4, preventing the thread take-up lever assembly 4 from rotating away from its initial position and then sliding to the working position, which would make it difficult to engage with the thread take-up drive arm 302.

[0026] When the ribbon embroidery is not in use, the thread take-up lever assembly 4 disengages from the thread take-up drive arm. At this time, the drive cam 301 rotates idling without driving the connecting rod. This no-load operation reduces the load on the embroidery machine spindle and stops the ribbon embroidery thread take-up lever from moving, preventing the top thread from being accidentally pulled out of the needle during the thread take-up process and causing the top thread to fall off.

[0027] This utility model also discloses a mixed embroidery device, including a ribbon embroidery mechanism and an embroidery mechanism spaced apart on a main beam. The ribbon embroidery mechanism is the ribbon embroidery mechanism described above, and the embroidery mechanism can be a flat embroidery mechanism, or sequin embroidery, bead embroidery, etc.

[0028] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
