Description

Technical Field

[0001] This utility model relates to a bead selection device for non-uniform beads. Background Technology

[0002] Faceted beads have two sides with different shapes, such as a flat surface and a patterned surface. When sewing or embroidering them, the faceted beads must be oriented with one side facing upwards and threaded onto a beading rod. Because faceted beads are mostly sheets with low thickness and need to be oriented, they cannot be threaded by a beading mechanism like ordinary beads. Currently, there is no crystal beading mechanism with high beading efficiency, and most faceted beads still need to be threaded onto the rod by hand, which makes it impossible to use faceted beads in large quantities.

[0003] To address the aforementioned issues, the applicant previously applied for several bead sorting devices that can quickly sort beads from the material area through the screening holes of a rotating disc. The rotating disc then carries a bead through the screening holes to a drop hole, where it falls and is threaded onto a threading rod. However, in actual use, when the bottom or most of the bead detaches from the bottom of the cylinder after being carried to the drop hole, the bead is prone to flipping and tilting due to unexpected factors, preventing the bead's hole from quickly engaging with the threading rod for threading. Factors such as uneven bead weight, cylinder tilt, or intermittent stops during the rotation of the disc to the drop hole can all cause the bead to flip before being threaded. Utility Model Content

[0004] This invention addresses the problems existing in the use of the prior art by providing a bead selection device that can effectively assist in the rapid, stable, and accurate threading of non-faceted beads onto a bead threading rod.

[0005] The technical solution of this utility model to solve the existing problems is: a bead selection device for non-planar beads, including an inclined cylinder set on a support frame and a rotating disk set at the bottom of the cylinder. The rotating disk has at least one screening hole for screening non-planar beads at a non-axial position, and each screening hole can screen and carry one bead. The bottom of the cylinder has a bead dropping hole, which is located in the middle or upper part of the inclined bottom of the cylinder. The bead dropping hole is set on the path of the screening hole as the rotating disk rotates. A bead-passing rod is provided at the bead dropping hole. An auxiliary bead spring-loaded rod is also provided in the cylinder above the bead dropping hole. The spring-loaded rod is fixed to the cylinder wall, and the end of the spring-loaded rod is set above the bead dropping hole to cooperate with the bead to be dropped in the screening hole of the bead dropping hole, assisting the bead to fall and pass through the bead-passing rod. The rotating disk is provided with a first drive motor to drive the rotating disk to rotate.

[0006] As a further improvement, the corresponding end of the spring-loaded rod is located at the upper end of the bead-threading rod.

[0007] As a further improvement, the support frame is connected to a bead arranging structure; the bead arranging structure includes a mounting frame, at least two sets of bead clamps for positioning the bead rod arranged along the axial direction of the bead rod, and a driving structure for driving the bead clamps to open and close alternately. The driving structure drives a corresponding number of bead clamps to open alternately, and satisfies the condition that at any given time, at least one set of bead clamps holds the positioning bead rod; the mounting frame is connected to the support frame.

[0008] As a further improvement, at least one or both clamping arms of the uppermost set of bead clamps are provided with a stop bar. When the clamping arms of the bead clamps are closed, the stop bar stops the beads on the bead threading rod as the clamping arms close. When the clamping arms of the bead clamps are open, the stop bar disengages from stopping the beads on the bead threading rod as the clamping arms open.

[0009] As a further improvement, the bottom of the cylinder is provided with at least one slag discharge hole on the rotation path of the screening hole, the diameter of the slag discharge hole is smaller than the diameter of the screening hole; the diameter of the slag discharge hole is greater than or equal to the outer diameter of the small diameter end of the unequal-sided bead; the lower part of the bottom of the cylinder forms the material area of ​​the bead, and the slag discharge hole is located in the area between the rotating disk and the drop bead hole when it rotates from the material area to the drop bead hole.

[0010] As a further improvement, the spring-loaded rod includes a connecting arm fixed to the cylinder wall, a spring-loaded arm extending into the ball-loaded hole, and a helical spring connecting the connecting arm and the spring-loaded arm.

[0011] As a further improvement, the drop hole is located at the highest position along the circumference of the bottom of the inclined cylinder; the bottom of the cylinder forms a material area for the beads, and a screening block is provided on the inner wall of the cylinder along the rotation path of the rotating disc screening hole. The screening block is located in the area between the rotating disc rotating from the material area to the drop hole.

[0012] As a further improvement, the cylinder is provided with a feeding hopper, and the feeding hopper is provided with a cover that fits with the upper end of the cylinder.

[0013] As a further improvement, the bottom of the cylinder is provided with a chassis that can be connected to a first drive motor. At least one stirring block is provided on the circumference of the chassis. The rotating disk is concentrically mounted on the chassis. The rotating disk is provided with a slot that mates with the stirring block. The stirring block passes through and protrudes from the rotating disk.

[0014] As a further improvement, the support frame is provided with an extension plate on one side of the cylinder, the first drive motor is mounted on the extension plate, and a transmission pulley assembly is provided between the first drive motor and the rotating disk; the cylinder is provided with a mounting groove for mounting a spring-loaded rod; the diameter of the drop bead hole is greater than or equal to the diameter of the screening hole; and the thickness of the rotating disk is less than the thickness of the screened beads.

[0015] Compared with existing technologies, this invention features an inclined cylinder with a rotating disk at the bottom. The rotating disk has at least one screening hole for selecting beads with different facets, each capable of carrying one bead. The bottom of the cylinder has a drop hole that mates with the screening hole, and a bead-passing rod at the drop hole. A drive motor rotates the rotating disk, and the screening hole on the rotating disk randomly selects suitable beads from the material beads inside the cylinder. The rotating disk then transports the beads to the drop hole. Typically, the beads with different facets are frustum-shaped with a bead-passing hole in the center. One side is flat, and the other is tapered. The flat bottom of the bead falls into the screening hole and is stably carried to the drop hole. The tapered side falls into the screening hole; because the tapered end has a small diameter and small area, friction is easily carried away by the rotation of the rotating disk, thus achieving the goal of selecting beads whose flat bottom mates with the screening hole. The selected flat-bottomed beads are transported to the bead drop hole. The portion of the bead that enters the drop hole first is supported by the bead-threading rod. Once fully inside, the bottom of the bead has no support and is prone to tipping over. Therefore, the spring-loaded auxiliary bead above the drop hole assists the top of the bead, preventing it from tipping over. This effectively improves the bead-threading efficiency of the bead-threading process. Attached Figure Description

[0025] See Figure 1-9 This embodiment discloses a bead selection device for non-planar beads, comprising an inclined cylinder 1 mounted on a support frame 40 and a rotating disk 11 located at the bottom of the cylinder 1. The rotating disk 11 has at least one screening hole 12 at a non-axial position for screening non-planar beads 8. Each screening hole 12 can screen one bead. Multiple screening holes 12 are typically provided, evenly distributed around the rotation axis on the circumference of the rotating disk 11, and can be positioned close to the periphery to maximize the number of screening holes 12. A bead drop hole 10 is provided at the bottom of the cylinder 1, located in the middle or upper part of the inclined bottom 13 of the cylinder. The drop hole 10 is located on the path of the screening hole 12 as the rotating disk 11 rotates. A bead-threading rod 2 is provided at the drop hole 10. An auxiliary bead spring-loaded rod 3 is also provided inside the cylinder 1 above the drop hole 10. The spring-loaded rod 3 is fixed to the cylinder wall of the cylinder 1. The end of the spring-loaded rod 3 is located above the drop hole 10 and is used to cooperate with the beads to be dropped in the screening hole 12 that enters the drop hole 10, assisting the beads to fall and be threaded onto the bead-threading rod 2. The rotating disk 11 is provided with a first drive motor 14 to drive the rotating disk 11 to rotate.

[0026] The bottom 13 of the inclined cylinder 1 is located below and is usually used as a material area for stacking beads. The beads are randomly stacked in the material area. The rotating disk 11 rotates, and the screening holes 12 on the rotating disk 11 pass through the material area in sequence. Based on probability, the non-planar beads 8 with suitable angles enter the screening holes 12. The non-planar beads 8 with flat bottoms enter the screening holes 12 and are wrapped by the screening holes 12. With the rotation of the rotating disk 11, the non-planar beads 8 in the screening holes 12 are transported one by one to the drop hole 10. The non-planar beads 8 with small diameter ends of conical surfaces enter the screening holes 12. Due to the small diameter end and the conical surface, the friction between them and the bottom 13 of the cylinder is small. With the rotation of the rotating disk 11, the non-planar beads 8 with small diameter ends of conical surfaces entering the screening holes 12 are easily carried out, ensuring that each bead entering the drop hole 10 of the screening hole 12 is oriented with its flat bottom facing down. The oriented, non-directional beads 8 are carried into the drop hole 10 by the screening hole 12 of the rotating disk 11 until the non-directional beads 8 are completely separated from the bottom of the cylinder 13. At this time, the non-directional beads 8 are easy to flip over. The spring rod 3 presses down on the non-directional beads 8. Combined with the bead threading rod, it can effectively prevent the non-directional beads 8 located in the drop hole 10 from flipping over, so that the non-directional beads 8 can be quickly and effectively threaded onto the bead threading rod 2.

[0027] To facilitate bead threading, the corresponding end of the spring-loaded rod 3 is located at the upper end of the bead threading rod 2. In this way, the spring-loaded rod 3 can cooperate with the hole of the non-faceted bead 8, which can better support the non-faceted bead 8, prevent the non-faceted bead 8 from flipping over, and effectively ensure that the non-faceted bead 8 can be threaded smoothly on the bead threading rod.

[0028] The support frame 40 is connected to a bead arranging structure 4. The bead arranging structure 4 includes a mounting frame, at least two sets of bead clamps 21 oriented along the axial direction of the bead threading rod 2, and a drive structure that drives the bead clamps 21 to open and close alternately. The drive structure drives a corresponding number of bead clamps 21 to open alternately, ensuring that at any given time, at least one set of bead clamps 21 holds the bead threading rod 2. The mounting frame is connected to the support frame 40. The bead arranging structure 4 can be any existing publicly available bead arranging structure. The drive structure includes a drive shaft, a cam structure located on the drive shaft that drives the corresponding bead clamps 21 to open and close, and a second drive motor 41 for the drive shaft.

[0029] At least one or both clamping arms of the uppermost set of bead clamps 21 are provided with a stop bar 22. When the clamping arm of the set of bead clamps 21 is closed, the stop bar 22 stops the beads on the bead threading rod 2 from falling as the clamping arm closes. When the clamping arm of the set of bead clamps 21 is opened, the stop bar 22 disengages from stopping the beads on the bead threading rod 2 as the clamping arm opens.

[0030] Multiple sets of bead clips 21 are used to position the bead-threading rod 2, ensuring its stable positioning and facilitating accurate bead threading. After the beads are threaded from the top of the bead-threading rod 2, they will slide down the rod 2 randomly and uncontrollably. When the bead clips 21 are closed, they may easily catch the falling beads. If the uppermost bead clip 21 catches a bead but does not hold the bead-threading rod 2, the bead may lose its positioning on the rod 2, resulting in inaccurate alignment between the upper end of the bead-threading rod 2 and the drop hole 10, thus affecting bead threading. A stop bar 22 is provided. When the uppermost set of bead clamps 21 closes, the beads threaded from the upper end of the bead threading rod 2 fall onto the stop bar 22. Driven by the drive structure, when the uppermost set of bead clamps 21 opens, the stop bar 22 disengages from the bead threading rod 2 as the clamping arm opens, allowing the beads to slide down the stop bar 22. By controlling the distance between the stop bar 22 and the uppermost bead clamps, the falling beads can be accurately controlled, ensuring an orderly and precise descent and preventing the uppermost bead clamps 21 from clamping the beads. The stop bar 22 can be a flexible steel wire rod mounted on the clamping arm, with a relatively small outer diameter. This way, when the stop bar 22 closes with the bead clamps and the clamping arm closes to clamp the beads, it will elastically avoid directly clamping the beads.

[0031] The bottom of the cylinder 1 is provided with at least one slag discharge hole 6 on the rotation path of the screening hole 12. The diameter of the slag discharge hole 6 is smaller than that of the screening hole 12; the diameter of the slag discharge hole 6 is greater than or equal to the outer diameter of the small-diameter end of the non-conical beads 8. The slag discharge hole 6 is located in the area between the rotating disk 11 and the drop hole 10. In this way, a certain probability will be generated when the conical small-diameter end of the non-conical beads 8 enters the screening hole 12. As the rotating disk 11 rotates and cooperates with the slag discharge hole 6, the beads enter the slag discharge hole 6 and are temporarily fixed in the slag discharge hole 6. The continuing rotation of the rotating disk 11 will touch the small-diameter end of the beads in the slag discharge hole 6 and squeeze the beads out, making it easier for the beads in the slag discharge hole to jump out, effectively screening out the beads with the small-diameter end orientation. The slag discharge hole 6 can also be used to discharge broken beads.

[0032] The spring-loaded rod 3 includes a connecting arm 31 fixed to the wall of the cylinder 1, a spring-loaded arm 32 extending into the bead drop hole 10, and a coil spring 33 connecting the connecting arm 31 and the spring-loaded arm 32, so that the spring-loaded arm 32 can provide better elasticity to assist the beads in cooperating with the bead threading rod 2.

[0033] The drop hole 10 is located at the highest point along the circumferential direction at the bottom of the inclined cylinder 1, and can be positioned directly above the bottom 13 of the inclined cylinder. A screening block 7 is provided on the inner wall of the cylinder 1 along the path of the rotating disk 11's screening hole 12. The screening block 7 is located in the area between the rotating disk 11 and the drop hole 10. The screening block 7 can stop beads that rotate with the rotating disk 11 but do not enter the screening hole 12, preventing beads from stacking inside and outside the screening hole 12, and preventing stacked beads from accidentally entering the drop hole 10 through the screening hole 12 and being threaded onto the bead threading rod 2.

[0034] The cylinder 1 is equipped with a feeding hopper 5, and the feeding hopper 5 is equipped with a cover 51 that mates with the upper end of the cylinder 1. The cover 51 is rotatably mounted on the cylinder 1. The outlet of the feeding hopper 5 leads directly to the feeding area.

[0035] The bottom 13 of the cylinder is provided with a chassis 15 that can be connected to a first drive motor 14. At least one stirring block 16 is provided on the circumference of the chassis 15. The rotating disk 11 is concentrically mounted on the chassis 15. The rotating disk 11 is provided with a slot that mates with the stirring block. The stirring block passes through and protrudes from the rotating disk 11. The stirring block 16 can be used to stir materials as the chassis 15 rotates, and at the same time, it can drive the rotating disk 11 to rotate. This structure simplifies the structure of the chassis 15 and the rotating disk 11.

[0036] The support frame 40 has an extension plate on one side of the cylinder 1, the first drive motor is mounted on the extension plate, and a transmission pulley assembly is provided between the first drive motor and the rotating disk 11; the cylinder 1 has an installation groove 30 for mounting the spring rod 3; the diameter of the drop bead hole 10 is greater than or equal to the diameter of the screening hole 12; the thickness of the rotating disk 11 is less than the thickness of the beads being screened, so that while the screening hole 12 carries beads with the flat bottom facing down, it is easier to screen out beads with the small diameter end facing down.
