Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a device for embroidering with a combination of beads and sequins. Background Technology

[0002] Existing bead and sequin embroidery machines that work with the same needle bar suffer from interference at their bead or sequin feeding points. Therefore, a retraction mechanism is needed for the bead and / or sequin feeding devices. Typically, during bead feeding, this retraction mechanism drives the sequin feeding device backward to avoid the bead clamps of the bead feeding device, preventing the protruding bead clamps from colliding with the sequin feeding device. While this structure solves the problem of feeding beads and sequins onto the same needle bar, the mutual avoidance results in low conveying efficiency and prevents simultaneous bead and sequin feeding onto the same needle bar. Furthermore, to improve efficiency, the number of embroidery heads is often increased on embroidery machines of limited length, leading to increasingly higher head densities and smaller head spacing in existing embroidery machines. This makes the installation of existing bead and sequin devices quite difficult. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a mixed embroidery device for beads and sequins, which is reasonably designed, requires no retreat structure, and occupies little space.

[0004] The technical solution adopted is as follows: A bead and sequin embroidery device includes a needle bar frame, a mounting frame, a bead feeding mechanism mounted on the mounting frame that feeds material to the same needle on the needle bar frame, and corresponding bead feeding drive mechanisms, a sequin feeding mechanism, and corresponding sequin feeding drive mechanisms.

The sequin feeding mechanism is mounted on a sequin feeding base plate. The sequin feeding drive mechanism includes a sequin feeding drive motor and a sequin feeding motor mounting frame. The sequin feeding base plate is located at the upper end of the bead feeding base plate. The bead feeding mechanism includes a bead feeding clamp that can slide and extend from the lower end of the feeding plate and a driving component for driving the bead feeding clamp. The bead feeding mechanism and the feeding plate mechanism are located on the same side of the needle bar frame and are set at a certain angle with the matching needle as the axis. The feeding plate drive motor is installed towards the side closer to the bead feeding mechanism. The bead feeding motor mounting bracket and / or the feeding plate motor mounting bracket are provided with a clearance notch for avoiding the drive motor. The drive motor is either a bead feeding drive motor or a feeding plate drive motor.

[0005] Furthermore, the feeding drive motor is installed on the side away from the needle bar frame, and the bead feeding motor mounting bracket is provided with a clearance notch to avoid the feeding drive motor.

[0006] Furthermore, the bead feeding drive mechanism also includes a drive slider connected to the drive component, a bead feeding drive arm disposed between the bead feeding drive motor and the drive slider, and a synchronous belt assembly disposed between the bead feeding drive arm and the bead feeding drive motor.

[0007] Furthermore, the feeding mechanism includes a pry bar that slides on the feeding base plate for prying the film and a cutter assembly located on one side of the feeding base plate.

Detailed Implementation

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

[0017] refer to Figure 1-9 A bead and sequin embroidery device includes a needle bar frame 1, a mounting frame 2, a bead feeding mechanism 3 mounted on the mounting frame 2 that feeds material to the same needle on the needle bar frame, and corresponding bead feeding drive mechanisms 4, sliver feeding mechanism 5, and corresponding sliver feeding drive mechanisms 6. The bead feeding mechanism 3 is mounted on a bead feeding base plate 7. The bead feeding drive mechanism 4 includes a bead feeding drive motor 401 and a bead feeding motor mounting frame 402. The sliver feeding mechanism 5 is mounted on a sliver feeding base plate 8. The sliver feeding drive mechanism 6 includes a sliver feeding drive motor 601 and a sliver feeding motor mounting frame 602. The sliver feeding base plate 8 is located at the upper end of the bead feeding base plate 7. The described bead feeding mechanism includes a bead feeding clamp 301 that can slide and extend from the lower end of the feeding plate and a driving component 302 that drives the bead feeding clamp. The bead feeding mechanism 3 and the feeding plate mechanism 5 are located on the same side of the needle bar frame 1 and are set at a certain angle with the matching needle as the axis. The feeding plate drive motor 601 is installed towards the side closer to the bead feeding mechanism 3, and the bead feeding drive motor 401 is installed towards the side closer to the feeding plate mechanism 5. The bead feeding motor mounting bracket 402 or / and the feeding plate motor mounting bracket 602 are provided with a clearance notch 9 for avoiding the drive motor. The drive motor is a bead feeding drive motor or a feeding plate drive motor.

[0018] In this embodiment, the sheet feeding drive motor 601 is installed on the side away from the needle bar frame 1 to prevent interference with the needle bar frame 1. The bead feeding motor mounting bracket 402 is provided with a clearance notch 9 to avoid the sheet feeding drive motor 601, providing space for the sheet feeding drive motor 601 to be installed, minimizing the width of the sheet feeding drive mechanism 6 and the bead feeding drive mechanism 4, which is suitable for embroidery machines with small head spacing.

[0019] The bead feeding base plate 7 is located at the lower end of the sheet feeding base plate 8. The bead feeding clamp and driving component on the bead feeding base plate can slide at the lower end of the sheet feeding base plate 8. During operation, they are not interfered with by the sheet feeding base plate 8. The two base plates are staggered, which minimizes the space occupied without interfering with each other. They can also feed materials to the same needle, realizing the sewing of gold sheets and beads in one stitch, which is highly efficient.

[0020] The bead feeding drive mechanism 4 further includes a drive slider 405 connected to the drive member 302, a bead feeding drive arm 403 disposed between the bead feeding drive motor 401 and the drive slider 405, and a synchronous belt assembly 404 disposed between the bead feeding drive arm 403 and the bead feeding drive motor 401. The bead feeding drive motor drives the bead feeding drive arm to swing through the synchronous belt assembly 404, thereby causing the drive slider 405 to slide. The drive slider causes the drive member to slide, driving the bead feeding clamp to clamp and feed the bead. This structure can completely adopt existing technology.

[0021] The feeding mechanism 5 includes a pry bar 501 for prying pieces that slides on the feeding base plate, and a cutter assembly 502 located on one side of the feeding base plate. An end seat 503 for mounting the cutter assembly 502 is provided on one side of the feeding base plate, and the upper end of the end seat is connected to the feeding motor mounting bracket. The feeding drive mechanism 6 further includes a feeding transmission assembly 603 located between the feeding drive motor and the pry bar, and a cutter transmission assembly 604 located between the feeding drive motor and the cutter.

[0022] The feeding motor mounting bracket 602 is provided with a first slot 10 for accommodating a portion of the feeding transmission assembly 603 and a second slot 11 for accommodating a portion of the cutting transmission assembly 604. Both the feeding transmission assembly 603 and the cutting transmission assembly 604 are arranged vertically.

[0023] The first slot 10 and the second slot 11 are axially arranged toward the output shaft 12 of the wafer feeding drive motor, and the width of the projected area of ​​the wafer feeding motor mounting bracket toward the wafer feeding drive motor is smaller than the width of the wafer feeding drive motor. This reasonable arrangement of the wafer feeding motor mounting bracket further reduces the overall volume of the wafer feeding drive structure.

[0024] The feeding transmission assembly 603 includes a feeding drive arm 6031 mounted on the output shaft 12 of the feeding drive motor, a paddle drive linkage 6032 connected to one end of the paddle lever and driving the paddle lever to paddle, and a feeding transmission rod 6033 located between the feeding drive arm and the paddle drive linkage. This structure can completely adopt existing technology. The feeding drive arm 6031 and the feeding transmission rod 6033 are located in the first slot 10. The feeding drive motor drives the feeding drive arm to swing, which in turn drives the feeding transmission rod 6033 to swing. The paddle drive linkage is coaxially mounted with the feeding transmission rod and will swing accordingly, driving the paddle lever to paddle.

[0025] The cutting blade transmission assembly 604 includes a cutting blade drive arm 6041 and a cutting blade transmission arm 6042 mounted on the output shaft 12 of the feeding drive motor, a cutting blade drive shaft 6043 connected to the cutting blade assembly, and a connecting rod assembly 6044 located between the cutting blade drive shaft and the cutting blade transmission arm. This structure can be entirely based on existing technology. The cutting blade drive arm 6041 and the cutting blade transmission arm 6042 are located within the second groove 11. The feeding drive motor drives the cutting blade drive arm 6041 to swing, which in turn drives the cutting blade transmission arm to rotate. The connecting rod assembly 6044 then drives the cutting blade drive shaft 6043 to rotate, causing the cutting blade to slice the blade.

[0026] The mounting frame 2 is equipped with a lifting mechanism 13 that can lift the entire mounting frame 2. The lifting mechanism 13 is a lifting cylinder, one end of which is connected to an external fixing structure and the other end is connected to the mounting frame 2. It can drive the mounting frame 2 to lift, that is, drive the feeding mechanism and the bead feeding mechanism to lift together.

[0027] A first sliding structure 14 is provided between the feed motor mounting bracket and the mounting bracket, and a second sliding structure 15 is provided between the bead feeding motor mounting bracket and the mounting bracket. The first and second sliding structures allow the feed motor mounting bracket and the bead feeding motor mounting bracket to slide laterally to switch between different needles, or to slide longitudinally away from the needle bar frame for retraction. The first and second sliding structures can be based entirely on existing technology. The lateral direction refers to the needle arrangement direction of the needle bar frame, and the longitudinal direction refers to the direction away from or towards the needle bar frame.

[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.
