Description

Technical Field

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

[0002] To improve efficiency, embroidery machines typically have multiple embroidery devices on a single head, such as bead embroidery, cord embroidery, and sequin embroidery. However, the space between adjacent heads is limited, and sometimes the head-to-head distance is minimized to further improve efficiency. The layout of the embroidery devices affects each other. In existing technology, cord embroidery devices occupy a large space and are usually installed directly at the front of the needle bar frame or on one side of the needle bar frame, protruding forward beyond the needle bar frame of the machine head. This is not conducive to the combined installation of cord embroidery devices with complex structures such as multi-bead or multi-sequin embroidery devices. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a rope embroidery device that occupies little space and is easy to combine and install with other complex embroidery devices.

[0004] The technical solution adopted is as follows: A rope embroidery device includes a rope embroidery device body disposed on either the left or right side of a needle bar frame. A connecting frame is provided between the needle bar frame and the rope embroidery device body. The rope embroidery device body is disposed between two adjacent needle bar frames. The projection surfaces of the needle bar frame and the rope embroidery device body facing the direction in which the needle bar frames are arranged completely or substantially overlap in the front-back direction on the inner side of the projection of the needle bar frame.

[0005] Furthermore, the main body of the rope embroidery device includes a rope feeding mechanism at the upper end and a first mounting frame for mounting the rope feeding mechanism; it also includes a rope swinging mechanism and a rope looping mechanism at the lower end, and a second mounting frame for mounting the rope swinging mechanism and the rope looping mechanism. A connecting plate is provided between the first and second mounting frames, and a lifting mechanism is provided between the first mounting frame and the connecting plate.

[0006] Furthermore, the lifting mechanism includes a drive cylinder for driving the lifting, and a slide rail assembly disposed between the first mounting frame and the connecting plate. The drive cylinder is disposed on the front side of the first mounting frame, and the slide rail assembly is disposed on the rear side of the first mounting frame.

[0007] Furthermore, the second mounting bracket includes an interconnected mounting plate and a motor mounting plate.

[0008] Furthermore, the rope swing mechanism includes a limiting groove on the front side of the mounting plate, a swing rod rotatably disposed in the limiting groove, and a torsion spring disposed on the swing rod. The swing rod is provided with a rope threading hole for the rope to pass through, and a detector for detecting the swing angle is provided on the rear side of the mounting plate.

[0009] Furthermore, the rope-tying mechanism includes a rope-tying ring, a drive motor for driving the rope-tying ring to rotate, and a synchronous pulley assembly for transmission. The drive motor is located on the rear side of the mounting plate and is mounted on the motor mounting plate.

[0010] Furthermore, the first mounting bracket, the connecting plate, and the second mounting bracket are arranged sequentially from top to bottom and are parallel to each other.

[0011] Furthermore, the first mounting bracket, the second mounting bracket, and the connecting plate are parallel to the needle bar frame.

Detailed Implementation

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

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and should not be construed as limiting this utility model.

[0018] refer to Figure 1-7 A rope embroidery device includes a rope embroidery device body 2 disposed on either the left or right side of a needle bar frame 1. A connecting frame 3 is provided between the needle bar frame 1 and the rope embroidery device body 2. The rope embroidery device body 2 is disposed between two adjacent needle bar frames 1. The projection planes of the needle bar frame 1 and the rope embroidery device body 2 toward the direction in which the needle bar frames are arranged completely or substantially overlap in the front-back direction.

[0019] The rope embroidery device body 2 is located in the space between two adjacent needle bar frames 1. It occupies little space to the left, right, front, and back, and hardly protrudes to the front of the needle bar frame. It makes reasonable use of the space between the two needle bar frames 1, leaving space in front of the needle bar frame 1 to facilitate the installation of other complex embroidery devices, such as multi-bead and multi-gold sequin devices.

[0020] The rope embroidery device body 2 includes a rope feeding mechanism 4 at the upper end, a first mounting frame 7 for mounting the rope feeding mechanism 4, and the drive motor of the rope feeding mechanism 4 is mounted on the rear side of the first mounting frame 7 to avoid occupying the space on the front side; it also includes a rope swinging mechanism 5 and a rope looping mechanism 6 at the lower end, and a second mounting frame 8 for mounting the rope swinging mechanism and the rope looping mechanism. A connecting plate 9 is provided between the first and second mounting frames, and a lifting mechanism 10 is provided between the first mounting frame 7 and the connecting plate 9.

[0021] The first mounting bracket 7, connecting plate 9, and second mounting bracket 8 are arranged sequentially from top to bottom and are parallel to each other. Preferably, the first mounting bracket, second mounting bracket, connecting plate, and needle bar frame 1 are also parallel. The parallel arrangement allows the various mechanisms to be arranged vertically, occupying vertical space, and the left-right and front-back dimensions of the projection plane of each mechanism towards the bottom are as consistent as possible to ensure that the rope embroidery device body 2 occupies little space in the left-right and front-back directions.

[0022] The lifting mechanism 10 includes a drive cylinder 1001 for driving the lifting, and a slide rail assembly 1002 disposed between the first mounting frame 7 and the connecting plate 9. The drive cylinder 1001 is located on the front side of the first mounting frame 7, and the slide rail assembly 1002 is located on the rear side of the first mounting frame 7. The slide rail assembly 1002 includes a slide rail 13 disposed on the first mounting frame 7 and a slider 14 disposed on the connecting plate 9 that cooperates with the slide rail 13. One end of the drive cylinder 1001 is mounted on the first mounting frame 7, and the other end is mounted on the connecting plate 9. Activating the drive cylinder 1001 causes the connecting plate 9 to slide up and down relative to the first mounting frame 7. Since the lower end of the connecting plate 9 is connected to the second mounting frame 8, the lifting mechanism 10 can drive the rope swing mechanism and the rope loop mechanism to lift and lower.

[0023] The second mounting bracket 8 includes a mounting plate 801 and a motor mounting plate 802 that are connected to each other.

[0024] The rope swing mechanism 5 includes a limiting groove 501 located on the front side of the mounting plate 801, a swing rod 502 rotatably located within the limiting groove 501, and a torsion spring 503 located on the swing rod 502. The swing rod 502 has a rope threading hole 11 for the rope to pass through. A detector 12 for detecting the swing angle is located on the rear side of the mounting plate 801. The rope ringing mechanism 6 includes a rope ring 601, a drive motor 602 for driving the rope ring 601 to rotate, and a synchronous pulley assembly 603 for transmission. The drive motor 602 is located on the rear side of the mounting plate 801 and is mounted on the motor mounting plate 802.

[0025] A cord clamp 15 is also provided on one side of the mounting plate 801. The function of the cord clamp 15 is to ensure that the cord remains stable during the embroidery process and to prevent the cord from falling off or becoming misaligned. By clamping the cord, the cord clamp ensures that it will not move during the embroidery process, thereby guaranteeing the accuracy and consistency of the embroidery pattern. The rope feeding mechanism 4 can be based entirely on existing technology. Its function is to feed the rope thread downwards. The rope thread is output from the rope feeding mechanism 4, passes through the rope threading hole 11 of the rope swing mechanism 5, and is transmitted to the rope-holding ring 601 via the rope clamp 15. During the rope embroidery process, the drive motor 602 drives the rope-holding ring 601 to cause the rope thread to swing back and forth off the center of the needle. This allows the needle to not directly embroider on the rope thread during embroidery, but instead to embroider the thread on both sides of the rope thread and then pass over it to fix it to the fabric. The faster the needle goes down, the faster the swing speed of the rope-holding ring 601 increases. The swing of the rope will pull the swing arm 502 of the rope swing mechanism to swing, while the torsion spring 503 drives the swing arm 502 to provide tension to the rope. The detector 12 on the rope swing mechanism 5 can detect the swing angle of the swing arm 502 and provide feedback in order to control the needle insertion speed and the swing speed of the rope loop, so as to maintain reasonable tension of the rope and avoid thread breakage or tangling.

[0026] The second mounting bracket 8 is adjustable left and right on the connecting plate 9, and a second slide rail assembly 11 is provided between the second mounting bracket 8 and the connecting plate 9. The installation position of the second mounting bracket 8 can be adjusted according to actual needs.
