Description

Technical Field

[0001] This utility model relates to the field of bead embroidery technology, and in particular to a bead selection mechanism for screening flat-bottomed beads with different surfaces. Background Technology

[0002] The beading mechanism in bead embroidery generally includes a tube for holding beads, a feed container at the top of the tube, and a beading rod inserted into the tube at one end. The feed container provides beads into the tube, and the rotation of the tube or propeller moves the beads, with a certain probability guiding the flowing beads to the beading end of the beading rod. The beading method described above is only applicable to regular beads. These beads do not require distinguishing between the front and back when sewing, so the beads can be used normally regardless of which end is inserted into the beading rod.

[0003] However, for some irregular beads, such as flat-bottomed beads with different top diameters (flat-bottomed beads with smaller top diameters and larger bottom diameters), it is necessary to strictly distinguish between the front and back sides when sewing. There is an urgent need to set up a mechanism that can screen such flat-bottomed beads to ensure that the flat-bottomed beads inserted by the beading rod are facing the same direction and will not affect the sewing effect. Summary of the Invention

[0004] To address the problems of the prior art, this utility model provides a bead selection mechanism for screening beads with different facets and flat bottoms, which can screen out beads with different facets facing down, ensuring the consistency of the beads' orientation and facilitating sewing.

[0005] The technical solution adopted is as follows:

[0006] A bead selection mechanism for screening beads with different flat bottoms in bead embroidery includes an inclined material tray and a material cylinder disposed on the inclined material tray. The inclined material tray is located inside the material cylinder and has bead dropping holes for the beads with different flat bottoms. The bead dropping holes are located in the middle or upper region of the inclined material tray within the material cylinder. The upper end of the inclined material tray is located inside the material cylinder and has a turntable that can drive the beads to rotate. The turntable has at least one first bead selection hole that can cooperate with the bottom surface of the beads with different flat bottoms. The bead dropping hole is located on the rotation path of the first bead selection hole. The turntable has a drive structure for driving the turntable to rotate. The first bead selection hole rotates with the turntable and can cooperate with the bead dropping hole in sequence. The bead dropping hole has a bead threading rod for threading beads.

[0007] Furthermore, the upper end of the material cylinder is provided with a feeding structure, which includes a feeding container. The lower end of the feeding container is provided with a discharge pipe. The bottom of the discharge pipe is provided with a baffle for controlling the discharge at the discharge port. The baffle is rotatably mounted on the discharge pipe. The discharge port of the discharge pipe of the feeding structure is located in the lower region of the inclined material cylinder.

[0008] Furthermore, the first bead selection hole is provided in multiple portions and is arranged circumferentially on the outer edge of the turntable.

[0009] Furthermore, the inclined material tray is provided with at least one second bead selection hole that can cooperate with the top surface of the non-flat bottom bead. The second bead selection hole is located on the rotation path of the first bead selection hole and cooperates with the first bead selection hole in sequence. The second bead selection holes are arranged circumferentially on the outer edge of the inclined material tray, and the diameter of the second bead selection hole is smaller than the outer diameter of the non-flat bottom bead.

[0010] Furthermore, the inclined tray is provided with an extension plate, and the driving structure is disposed on the extension plate.

[0011] Furthermore, the drive structure includes a drive motor, a drive shaft located at the center of the turntable, and a synchronous belt pulley assembly located between the drive motor and the drive shaft.

[0012] Furthermore, the ball drop hole is located at the very top of the inclined feed tray.

[0013] Furthermore, the turntable is provided with at least one stirring protrusion for stirring materials.

[0014] Furthermore, the inclined material tray has a rotatable stirring disc at its center, and the stirring disc has a plurality of stirring protrusions arranged circumferentially. The stirring disc is mounted on the drive shaft of the disc, and the disc has through grooves for the stirring protrusions to pass through.

[0015] Furthermore, the thickness of the turntable at least at the first bead selection hole is less than the thickness of the non-flat bottom bead; a stop brush is provided above the turntable inside the material cylinder at the path of the first bead selection hole; a first gap is provided at the position corresponding to the stop brush and the material tray, the first gap being greater than or equal to the thickness of one non-flat bottom bead and less than the thickness of two non-flat bottom beads; the inclined material tray is provided with a groove for accommodating the bead threading rod at the bead drop hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a bead selection mechanism for screening beads with non-flat bottoms in bead embroidery. The main purpose is to screen beads with non-flat bottoms, where the bottom surface is flat and the diameter of the bottom surface is larger than the diameter of the top surface. The selection mechanism includes an inclined tray and a cylinder. The inclined tray has a bead dropping hole for dropping the beads, and a rotatable bead-feeding turntable is located at the upper end of the inclined tray. The turntable has a first bead selection hole that mates with the bottom surface of the bead. A second bead selection hole that mates with the top surface of the bead can also be provided at a corresponding location on the inclined tray. If the bottom of the bead is facing down, it will be easily inserted into the first bead selection hole and will not fall out. As the turntable rotates, the bottom-facing bead will move to the drop bead hole for threading. If the top of the bead is facing down, it will not fit the first bead selection hole. When the turntable rotates, there is a certain chance that the bead will fall out of the first bead selection hole. When the first bead selection hole coincides with the second bead selection hole, the top of the bead will sink into the second bead selection hole and become inserted into it. When the turntable rotates again, the bead will pop out from both the first and second bead selection holes. In this way, it is ensured that the beads transported to the threading rod are all bottom-facing, achieving the purpose of bead selection and facilitating subsequent sewing.

Detailed Implementation

[0026] The present invention will be further described below with reference to specific embodiments.

[0027] refer to Figure 1-9 A bead selection mechanism for screening beads with different flat bottoms in bead embroidery includes an inclined material tray 1 and a material cylinder 2 disposed on the inclined material tray. The inclined material tray 1 is located inside the material cylinder 2 and has bead dropping holes 3 for the beads with different flat bottoms 5. The bead dropping holes 3 are located in the middle or upper region of the inclined material tray inside the material cylinder 2. The upper end of the inclined material tray 1 is located inside the material cylinder 2 and has a turntable 4 that can drive the beads to rotate. The turntable 4 has at least one first bead selection hole 6 that can cooperate with the bottom surface 501 of the beads with different flat bottoms 5. The bead dropping hole 3 is located on the rotation path of the first bead selection hole 6. The turntable 4 is provided with a drive structure 10 for driving the turntable 4 to rotate. The first bead selection hole 6 rotates with the turntable 4 and can cooperate with the bead dropping hole 3 in sequence. The bead dropping hole 3 is provided with a bead threading rod 13 for threading beads.

[0028] The non-uniform flat-bottomed bead 5 includes a bottom surface 501 and a top surface 502. The diameter of the bottom surface 501 is larger than the diameter of the top surface 502, so the diameter of the first bead selection hole 6 is larger than the diameter of the second bead selection hole 7. In this embodiment, a conical surface is provided between the bottom surface and the top surface. The non-uniform flat-bottomed bead 5 is also usually provided with a pinhole, which can be used to cooperate with the bead threading rod 13 to thread the bead onto the bead threading rod 13.

[0029] The rotation of turntable 4 causes the non-planar flat-bottomed beads 5 to rotate inside the material cylinder 2, for example... Figure 7 If the flat-bottomed bead 5 with its bottom surface 501 facing down is inserted into the first bead selection hole 6 and mates with it, it will not easily fall out of the first bead selection hole 6. The rotation of the turntable 4 directly transports the bottom-down bead to the bead dropping hole for dropping; for example... Figure 8 If the flat-bottomed bead 5 with the top surface 502 facing down is inserted into the first bead selection hole 6, since the diameter of the first bead selection hole 6 is larger than the diameter of the top surface 502, when the turntable rotates, the inner wall of the first bead selection hole 6 collides and impacts with the conical surface, and the bead is more likely to detach from the first bead selection hole 6.

[0030] Preferably, the inclined tray 1 is provided with at least one second bead selection hole 7 that can mate with the top surface 502 of the non-uniform flat-bottomed bead 5. The second bead selection hole 7 is located on the rotation path of the first bead selection hole 6 and mates with the first bead selection hole 6 sequentially. The second bead selection holes 7 are arranged circumferentially on the outer edge of the inclined tray 1. Even if the bead with its top surface facing down is still stuck in the first bead selection hole 6 and rotates with the turntable 4, when the first bead selection hole 6 and the second bead selection hole 7 coincide, the top surface 502 will sink and get stuck in the second bead selection hole 7 because of the mating of the top surface 502 and the second bead selection hole 7. When the turntable continues to rotate, the bead will be pushed by the side wall of the first bead selection hole 6 and pop out or be carried out from the second bead selection hole. The diameter of the second bead selection hole is smaller than the outer diameter of the non-uniform flat-bottomed bead.

[0031] The second bead-selecting hole 7 is located on the rotation path of the first bead-selecting hole 6 and is sequentially engaged with the first bead-selecting hole 6, such as... Figure 3 For example, in this embodiment, the turntable 4 rotates clockwise, so the second bead selection hole 7 is located on the left side.

[0032] This invention aims to select beads with their bottom surface facing down. A turntable 4 rotates the flat-bottomed beads 5 (bottom surface down, top surface up) to the drop hole 3, 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 desired selection. Because the material cylinder and inclined tray are tilted, the beads will fall into the lower part of the material cylinder. Therefore, the drop hole 3 is located in the middle or upper part of the material cylinder 2. Preferably, the drop hole 3 is located at the very top of the inclined tray 1.

[0033] The upper end of the material cylinder 2 is provided with a feeding structure 8, which includes a feeding container 801 and a discharge pipe 802 at the lower end of the feeding container 801. A baffle 803 for controlling the discharge is located at the bottom of the discharge pipe 802 at the discharge port. The baffle 803 is rotatably mounted on the discharge pipe 802. The discharge port of the discharge pipe 802 is located in the lower region of the inclined material cylinder. The feeding structure 8 can fully utilize existing technology. Under gravity, the feeding structure 8 automatically discharges material. Material is added at the feeding container 801, and the beads fall through the discharge pipe 802 to the baffle 803. Under gravity, the baffle 803 rotates and opens, allowing the beads to fall from the discharge port. When enough beads have fallen into the material cylinder, the baffle 803 will be blocked by the beads, gradually reducing its opening or even closing. That is, when the height of the accumulated beads is high enough, the baffle 803 can be forced to close. The upper end of the material cylinder 2 is also provided with a cover plate 18 to prevent the beads from falling out.

[0034] Multiple first bead selection holes 6 are provided and arranged circumferentially on the outer edge of the turntable 4. Having multiple first bead selection holes 6 allows for the simultaneous transport of multiple beads, resulting in higher efficiency.

[0035] The thickness of the turntable 4 at least at the first bead selection hole 6 is less than the thickness of the non-uniform flat-bottomed bead 5, making it easier for misfit beads to pop out or be carried out from the first bead selection hole 6; a stop brush 19 is provided above the turntable 4 inside the material cylinder 2, along the path of the first bead selection hole 6; a first gap A is provided at the position of the stop brush corresponding to the material tray 1, the first gap A being greater than or equal to the thickness of one non-uniform flat-bottomed bead 5 and less than the thickness of two non-uniform flat-bottomed beads 5; for example Figure 7 , 8 When the turntable 4 drives the bead past the stop brush 19, the stop brush will brush away the bead that overlaps on the first bead selection hole 6, ensuring that one first bead selection hole 6 corresponds to only one bead.

[0036] The second bead selection hole 7 is provided in multiple parts and is arranged circumferentially on the outer edge of the inclined material tray 1. The second bead selection hole 7 is a through hole. The purpose of setting the second bead selection hole 7 is not only to screen beads, but also to filter debris. Debris from beads that fall from the feeding structure 8 can also fall and be discharged through the second bead selection hole 7.

[0037] The inclined tray 1 has an outwardly extending plate 9, and the drive structure 10 is disposed on the extending plate 9. The drive structure 10 includes a drive motor 1001, a drive shaft 1002 disposed at the center of the turntable 4, and a synchronous pulley assembly 1003 disposed between the drive motor 1001 and the drive shaft 1002. The drive motor 1001 drives the drive shaft 1002 to rotate through the synchronous pulley assembly 1003, thereby driving the turntable 4 to rotate.

[0038] Preferably, the turntable 4 is provided with at least one stirring protrusion 1101 for stirring the material. Alternatively, the inclined material tray 1 has a rotatable stirring turntable 11 at its center for stirring. The stirring turntable 11 has a plurality of stirring protrusions 1101 arranged circumferentially. The stirring turntable 11 is mounted on the drive shaft 1002 of the turntable 4. When the stirring turntable 11 rotates, it can stir the beads in the material cylinder, making the beads evenly distributed and easier to get into the first bead selection hole. The stirring turntable 11 and the turntable 4 can be driven by the same drive structure 10, or they can be driven by separate drivers.

[0039] In one embodiment, the stirring turntable 11 can be integrally formed with the turntable 4, the stirring protrusion 1101 is set close to the center of the turntable 4, and the first bead selection hole is set on the outer edge of the turntable 4.

[0040] In another embodiment, the stirring disc 11 can also be separately arranged from the disc 4. The disc 4 and the stirring disc 11 are mounted on the same drive shaft 1002. The stirring disc 11 can rotate independently and is located at the center of the inclined material tray 1. The disc 4 covers the stirring disc 11 and has a through groove 12 for the stirring protrusion 1101 to pass through. A bearing is provided between the inclined material tray 1 and the drive shaft 1002, so that the drive shaft 1002 can rotate independently, driving the stirring disc 11 and the disc 4 to rotate without affecting the inclined material tray 1.

[0041] The inclined material tray 1 has a groove 14 at the bead drop hole 3. The groove 14 is provided to provide space for the beads to drop and to adjust the bead threading rod 13.

[0042] The bead selection mechanism provided by this utility model can be used in a bead feeding device. The bead feeding device includes a mounting frame 15, with a bead selection mechanism connected to the upper end of the mounting frame 15. The mounting frame 15 is also provided with a fixing mechanism 16 for fixing the bead threading rod. The bead arranging mechanism includes several clamping structures 1601 arranged in layers, and also includes a driver 17 that drives each clamping structure 1601 to open alternately. When the driver 17 drives the clamping structure 1601, it must ensure that at least one clamping structure clamps the bead threading rod 13 at any time.

[0043] 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.
