Detailed Implementation

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

[0017] refer to Figure 1-8A driving device for threading non-planar beads includes a bead selection mechanism 1 for screening non-planar beads 5, a bead threading rod 2 for threading beads, and a bead arranging mechanism 3 for fixing the bead threading rod. The bead selection mechanism 1 includes a material tray 11 and a material cylinder 12 disposed above the material tray. The material tray 11 is provided with bead dropping holes 111 for non-planar beads. A turntable 13 is disposed above the material tray and inside the material cylinder to drive the beads to rotate. The turntable 13 is provided with at least one first bead selection hole 131 that can cooperate with the bottom surface 51 of the non-planar beads 5. The bead dropping hole 111... Located on the rotation path of the first bead selection hole 131, the first bead selection hole 131 rotates with the turntable 13 and can cooperate with the drop bead hole 131 in sequence. The bead arranging mechanism 3 includes several clamping structures 31 arranged in layers, and also includes a drive motor 4 and a motor mounting plate 41 that can simultaneously drive the turntable of the bead selection mechanism 1 to rotate and drive the clamping structures 31 to open alternately. A first transmission structure 42 is provided between the drive motor 4 and the bead selection mechanism 1; a second transmission structure 43 is provided between the drive motor 4 and the bead arranging mechanism 3.

[0018] The flat-bottomed bead 5 is usually also provided with a pinhole, which can be used to thread the bead onto the bead threading rod 13.

[0019] The bead has a bottom surface 51 and a top surface 52. The bottom surface 51 is usually flat, while the other side has a specific shape. The diameter of the bottom surface is larger than the diameter of the top surface. When embroidering beads, the loose beads need to be oriented and threaded onto the bead threading rod by the bead selection mechanism 1.

[0020] The rotation of turntable 13 causes the non-planar beads 5 to rotate inside the barrel 12, such as Figure 7 If the bottom-facing bead 5 is inserted into the first bead selection hole 131 and engages with it, it will not easily fall out. The rotating turntable 13 directly transports the bottom-facing bead to the drop hole for placement; if... Figure 8 If the bead 5 with the top surface 52 facing down is inserted into the first bead selection hole 131, since the diameter of the first bead selection hole 131 is larger than the diameter of the top surface 52, when the turntable rotates, the inner wall of the first bead selection hole collides with the side wall of the bead, and the bead is more likely to detach from the first bead selection hole 131.

[0021] Preferably, the feed tray 11 is provided with at least one second bead-selecting hole 112 that can mate with the top surface 52 of the non-planar bead 5. The second bead-selecting hole 112 is located on the rotation path of the first bead-selecting hole 131 and mates with the first bead-selecting hole in sequence. The second bead-selecting holes 112 are arranged circumferentially on the outer edge of the inclined feed tray, and the diameter of the second bead-selecting hole is smaller than the outer diameter of the non-planar bead. At least one elastic body a is provided inside the feed cylinder on the rotation path of the first bead-selecting hole. The elastic body a is an elastic pressure plate. Preferably, the elastic body a is located at the bead drop hole to assist the non-planar bead 5 in dropping.

[0022] When the top surface 52 of the non-sided bead 5 faces downward and is inside the first bead selection hole 131, and the first bead selection hole 131 coincides with the second bead selection hole 112, the top surface 502 will sink and get stuck in the second bead selection hole 112 due to the cooperation between the top surface 52 and the second bead selection hole 112. As the turntable continues to rotate, the bead will be pushed by the side wall of the first bead selection hole 131 and pop out or be carried out from the first and second bead selection holes. An elastic body a is set to limit the bead. When the bead passes under the elastic body a, the elastic body a pushes the bead to fall, and the bead is not easy to tilt or flip. The bead threading and dropping is more stable, and the needle hole is easier to pass through the bead threading rod 2.

[0023] Preferably, the material tray 11 is inclined, and multiple first bead selection holes 131 are arranged circumferentially on the outer edge of the turntable. The inclined material tray 11 allows beads to be threaded under gravity when entering the drop hole. This invention aims to select beads with their bottom surface facing down. The turntable 13 rotates the beads 5 (bottom surface down, top surface up) to the drop hole 111, causing them to fall under gravity. Therefore, the drop hole cannot be located in an area covered by beads, otherwise multiple beads will fall, failing to achieve the purpose of bead selection. Because the material cylinder and inclined material tray are inclined, the beads will fall to the lower part of the material cylinder, so the drop hole 111 is located in the middle or upper part of the material cylinder 12. Preferably, the drop hole 3 is located at the very top of the inclined material tray 11.

[0024] In one implementation, the material tray 11 is horizontally arranged. The first transmission structure 42 includes a first synchronous pulley assembly 421 disposed between the drive motor 4 and the turntable 13; the second transmission structure 43 includes a second synchronous pulley assembly 431 disposed between the drive motor 4 and the clamping structure 31. The first and second synchronous pulley assemblies are arranged in parallel. The drive motor 4 drives the turntable 13 to rotate through the first synchronous pulley assembly 421, and at the same time drives the clamping structure 31 to open sequentially through the second synchronous pulley assembly 431.

[0025] In another embodiment, the material tray 11 is inclined. The first transmission structure 42 includes a first synchronous pulley assembly 421 disposed between the drive motor 4 and the turntable 13, and a transmission pressure roller structure 422 pressed onto the first synchronous belt 4211 of the first synchronous pulley assembly 421. Because the material tray is inclined, the output shaft of the drive motor is not parallel to the output shaft of the material tray, so a transmission pressure roller structure is required for transmission.

[0026] The transmission pressure roller structure 422 includes a pressure roller mounting bracket 4221 for mounting the transmission pressure roller, and a transmission pressure roller 4222 rotatably mounted on the pressure roller mounting bracket. The transmission pressure roller 422 can be mounted on the pressure roller mounting bracket via bearings. When the first synchronous belt 4211 moves, the transmission pressure roller rotates accordingly for transmission.

[0027] The turntable and clamping structure are driven by a single drive motor, which reduces the overall space occupied by the structure, saves costs, and facilitates installation and disassembly.

[0028] The material cylinder is also provided with a feeding mechanism 6 above it. The feeding mechanism 6 includes a feeding container 61. The lower end of the feeding container 61 is provided with a discharge pipe 62. The bottom of the discharge pipe 62 is provided with a baffle 63 for controlling the discharge and a baffle arm 631 connected to the baffle at the discharge port. The baffle arm is rotatably mounted on the discharge pipe. The feeding mechanism also includes a driving component 64 for driving the baffle to rotate.

[0029] The drive assembly 64 includes a first drive shaft 641, a mounting bracket b for mounting the first drive shaft 641, a drive cam 642 disposed on the first drive shaft 641, and a transmission rocker arm 643 disposed between the drive cam 642 and the baffle arm 631. One end of the transmission rocker arm 643 cooperates with the drive cam 642, and the other end cooperates with the baffle arm 631, which can drive the baffle arm to open or close the baffle. The mounting bracket b is disposed on the upper end of the motor mounting plate, and a gear transmission structure 644 is provided between the first drive shaft and the output shaft of the drive motor.

[0030] A transmission rocker arm 643 is rotatably mounted on the upper end face of the material cylinder. A torsion spring is provided between the transmission rocker arm 643 and the material cylinder. One end of the transmission rocker arm 643 is engaged with the pin c at the upper end of the baffle arm 631. The torsion spring drives the transmission rocker arm 643. The transmission rocker arm 643, in conjunction with the pin c, keeps the baffle in a normally closed state. The drive motor drives the first drive shaft 643 to rotate through the gear transmission structure 644. The rotation of the first drive shaft 643 drives the drive cam 642 to rotate. The drive cam 642 is an eccentric cam. The eccentric part rotates and engages with the transmission rocker arm 643. The transmission rocker arm 643 drives the baffle arm 631 to rotate, causing the baffle to open and the material balls to fall down from the discharge pipe. When the drive cam 642 continues to rotate and the eccentric part moves away from the transmission rocker arm 643, the transmission rocker arm 643 is reset under the drive of the torsion spring, causing the baffle to close and stopping the material falling.

[0031] The bead-arranging mechanism 3 includes a bead-arranging mounting frame 32 for mounting clamping structures 31. Inside the mounting frame is a second drive shaft 9 that drives several clamping structures to open alternately. A second synchronous pulley assembly 431 is located between the drive motor and the second drive shaft 9. The drive motor drives the second drive shaft 9 to rotate via the second synchronous pulley assembly 431, thereby driving the clamping structures to open alternately. It is necessary to ensure that at least one clamping structure clamps the bead-threading rod at any given time.

[0032] The turntable 13 is provided with at least one stirring protrusion 71 for stirring materials, or the material tray has a rotatable stirring turntable 7 at its center for stirring. The stirring turntable has a plurality of stirring protrusions 71 arranged circumferentially. The stirring turntable is mounted on the drive shaft of the turntable 13, and the turntable has through grooves 8 for the stirring protrusions to pass through. The drive motor can drive the stirring turntable 7 to rotate the turntable 13 together, stirring and feeding materials. Alternatively, stirring protrusions can be directly provided on the turntable for stirring.

[0033] 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 within the patent protection scope of the present utility model.
