Description

Technical Field

[0001] This utility model relates to the field of bead embroidery technology, and in particular to a bead conveying device that can be used for directional bead conveying. Background Technology

[0002] Existing bead feeding devices include a cylinder for holding beads, a bead guide rod for threading and feeding beads, and a bead feeding structure located at the lower end of the guide rod. The upper end of the guide rod is usually used for threading beads independently or in conjunction with a bead threading device, and then conveys the beads downwards after threading. The upper end of the guide rod can be directly inserted into the cylinder, and the beads rotate inside the cylinder, threading onto the guide rod with a certain probability; alternatively, a conveying channel can be set between the cylinder and the guide rod to transport the beads to the guide rod for threading. However, the above-mentioned bead feeding devices cannot directionally thread beads with two different sides.

[0003] For a horizontally placed conveyor channel, if the guide rod is positioned on one side of the channel and its upper surface is at the same height as the bottom surface of the channel, the bead will move horizontally to the guide rod. Once the guide rod is aligned with the bead hole, the bead will pass through it under gravity. However, for an inclined conveyor channel or a channel whose bottom surface is much higher than the upper surface of the guide rod, the bead will not fall smoothly into the guide rod after exiting the channel, making it difficult to align the bead hole with the guide rod and complete the bead threading process. Therefore, there is an urgent need for a bead conveying device that can transport the bead to the guide rod to complete the threading process. Summary of the Invention

[0004] To address the problems of the prior art, this utility model provides a two-sided bead conveying device for bead embroidery, which can move the beads from the conveying channel to the bead guide rod for threading, and the beads move smoothly without easily flipping or getting stuck.

[0005] The technical solution adopted is as follows:

[0006] A bead conveying device for bead embroidery includes a conveying trough and an inclined bead conveying channel. The conveying channel is located at a corresponding position in the conveying trough. The bottom surface of the conveying trough has a bead drop hole that cooperates with a bead guide rod. The conveying trough is provided with a rotatable driving component. The driving component has a corresponding driving structure. The driving component has at least one limiting hole that can accommodate beads and push the beads to rotate within the conveying trough. The bottom surface of the conveying trough has a smooth sliding surface or several sliding surfaces connected in sequence between the conveying channel and the bead drop hole for the beads to slide. The sliding surface has an inclined angle at the point where it cooperates with the conveying channel to receive beads output from the inclined channel. The inclined angle of the sliding surface gradually decreases to a plane from the corresponding point in the conveying channel to the bead drop hole. At least before the beads enter the bead drop hole, the sliding surface is a plane. The bead drop hole and the conveying channel are located at different positions.

[0007] Furthermore, the driving component has several limiting holes arranged circumferentially, each limiting hole being able to accommodate one bead.

[0008] Furthermore, the limiting hole is provided with a limiting surface on its inner side, and the distance between the limiting surface and the side wall of the conveying bottom groove is adapted to the diameter of the conveyed bead.

[0009] Furthermore, the end face of the drive component that mates with the sliding surface is provided with an inclined surface that mates with the sliding surface.

[0010] Furthermore, the drive structure includes a drive motor located at the upper end of the drive component and a mounting bracket for mounting the drive motor.

[0011] Furthermore, the conveying channel is inclined at the upper end of the conveying trough, and the inclination angle of the conveying channel is greater than or equal to the inclination angle of the sliding surface near the conveying channel.

[0012] Furthermore, the sliding surface has a groove at the inclined angle and at the corresponding position inside the conveying groove to accommodate the bead and cooperate with the side wall of the bead.

[0013] Furthermore, the conveying channel is located on the side directly opposite the drop ball hole.

[0014] Furthermore, the diameter of the drop hole is greater than or equal to the diameter of the bead.

[0015] Furthermore, the conveying groove is a circular groove set on the mounting plate; the drop hole is provided with a guide rod for threading beads.

[0016] Furthermore, the conveying bottom groove is provided with a climbing sliding surface that connects with the sliding surface from the drop hole to the point where it cooperates with the conveying channel. The climbing sliding surface is located on the path of the drop hole as it rotates with the drive component. The climbing sliding surface is a smooth sliding surface or several sliding surfaces that are connected in sequence to allow the beads to slide.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention solves the problem of difficulty in threading beads after they fall into an inclined conveying channel, and provides a bead conveying device for bead embroidery. The device includes a conveying trough with a conveying channel and bead dropping holes at different workstations. A drive component for rotating the beads is located at the upper end of the conveying trough, and the drive component has at least one limiting hole, each capable of accommodating one bead. The bottom surface of the conveying trough has a smooth sliding surface or several sequentially connected sliding surfaces for bead sliding. The inclination angle of the sliding surface gradually decreases from near the conveying channel to the bead dropping hole. The bead falls from the conveying channel into the limiting hole and slides on the sliding surface under the drive of the drive component. As it slides from the conveying channel to the bead dropping hole, the inclination angle of the bead gradually decreases, eventually becoming horizontal at the bead dropping hole. This allows the bead to slide smoothly and prevents it from tipping over. The limiting holes limit the bead's movement, ensuring it falls from the bead dropping hole and is smoothly and orientedly threaded onto the guide rod.

[0019] The beads drop smoothly and move smoothly when rotating, making them less prone to flipping or getting stuck. When they enter the bead drop hole, they can be smoothly inserted into the guide rod, ensuring the stability and accuracy of subsequent sewing and embroidery. Attached Figure Description

[0027] Among them, there are conveying bottom groove 1, conveying channel 2, guide rod 3, drop hole 4, driving component 5, limiting hole 51, driving structure 6, driving motor 601, mounting bracket 602, sliding surface 7, driving surface 8, limiting surface 9, inclined surface 10, groove 11, mounting plate 12, bead arranging structure 13, beads 14, and bead screening mechanism 15. Detailed Implementation

[0028] The present invention will be further described below with reference to specific embodiments.

[0029] refer to Figure 1-8 A bead conveying device for bead embroidery includes a conveying trough 1 and an inclined bead conveying channel 2. The upper end of the conveying channel 2 serves as a bead inlet and can be connected to a bead screening mechanism 15 that outputs beads in a directional manner.

[0030] The conveying channel 2 is located at the corresponding position of the conveying trough 1. The bottom surface of the conveying trough 1 is provided with a drop hole 4 that cooperates with the guide rod 3. The drop hole 4 and the conveying channel 2 are located at different positions. The conveying trough 1 is provided with a rotatable driving component 5. The driving component 5 is provided with a corresponding driving structure 6. The driving component 5 is provided with at least one limiting hole 51 that can accommodate beads and push the beads to rotate within the conveying trough 1. The bottom surface of the conveying trough 1 is provided with a smooth sliding surface 7 or several sliding surfaces 7 connected in sequence between the conveying channel 2 and the drop hole 4 for the beads to slide. The sliding surface 7 is located at the position where it cooperates with the conveying channel 2 and has an inclined angle to receive the beads output from the inclined channel. The inclination angle of the sliding surface 7 gradually decreases from the corresponding position of the conveying channel 2 to the drop hole 4. At least before the beads enter the drop hole 4, the sliding surface is a plane. Preferably, in order to facilitate bead threading, this plane can usually be set as a horizontal plane, but it can also be a plane with a slight inclination angle. Typically, the conveying channel 2 is connected to the bead sorting mechanism 15. After sorting, the beads 14 enter the conveying channel and then fall from the conveying channel 2 into the conveying trough 1. The driving component 5 drives the beads 14 to slide to the guide rod 3 for threading. To ensure that the beads can smoothly pass through the guide rod, the diameter of the drop hole 4 needs to be greater than or equal to the diameter of the beads. Preferably, the diameter of the drop hole 4 is greater than the diameter of the beads, ensuring that the beads can definitely fall from the drop hole 4. At least before the beads enter the drop hole 4, the sliding surface is flat, so that the beads remain horizontal before entering the drop hole, and there will be no jamming when entering the drop hole. The beads can fall into the guide rod 3 under the action of gravity. If the beads 14 enter the drop hole 4 at an angle, the bead hole will be difficult to align with the guide rod, causing the beads to jam.

[0031] The conveying channel 2 is inclined at the upper end of the conveying trough 1, and the inclination angle of the conveying channel 2 is greater than or equal to the inclination angle of the sliding surface 7 near the conveying channel. To ensure that the beads 14 fall smoothly into the sliding surface 7, the inclination angle of the conveying channel 2 must be at least equal to the inclination angle of the sliding surface 7 near the conveying channel, and preferably greater than the inclination angle of the sliding surface 7. If the inclination angle of the sliding surface 7 is too large, the beads are prone to flipping during descent, making it difficult to ensure the correct orientation of the beads and affecting the subsequent sewing effect.

[0032] The sliding surface 7 near the conveying channel 2 is not made into a flat surface. This is to prevent the beads from flipping over and to prevent the beads from getting stuck at the output port of the conveying channel 2. If the sliding surface 7 is flat, the conveying trough 1 needs to be set with sufficient depth for the beads to fall. Otherwise, the beads will get stuck at the output port and will not be able to come out. In this way, the beads have enough space to flip over, and if the height from which the beads fall is too high, the beads will not fall smoothly and will easily flip over.

[0033] The inclination angle of the sliding surface 7 located at the corresponding position in the conveying channel 2 to the ball drop hole 4 gradually decreases. It can be transformed into a horizontal surface in advance or smoothly, but should at least be transformed into a horizontal surface before the bead enters the ball drop hole 4. The gradually decreasing inclination angle allows the bead to move smoothly under the push of the drive component 5, reducing the likelihood of bead jamming. Adjacent sliding surfaces 7 connect smoothly, facilitating the sliding of the bead 14. This allows the bead to gradually change from an inclined state to a horizontal state before moving to the ball drop hole for threading.

[0034] Preferably, the driving member 5 has several limiting holes 51 arranged circumferentially to cooperate with the beads. Each limiting hole 51 can accommodate one bead 14. When the limiting hole 51 is aligned with the conveying channel 2, the bead falls into the limiting hole 51 and slides as the driving member 5 rotates. Setting multiple limiting holes 51 can transport multiple beads simultaneously, improving efficiency. The sidewall of the limiting hole 51 includes two sides and a limiting surface 9, one of which forms a driving surface 8 as the driving member 5 rotates. When the driving member 5 rotates, it cooperates with the bead 14 through the driving surface 8, pushing the bead 14 to slide.

[0035] The distance between the limiting surface 9 and the side wall of the conveying groove 1 is adapted to the diameter of the conveyed bead, so as to adapt to the corresponding width of the bead on the sliding surface 7 at different inclination angles. The width refers to the width of the projection of the bead onto the bottom surface. The limiting hole 51 is used to limit the bead 14 and drive the bead 14 to slide, so as to ensure that the bead can be accurately passed through the guide rod. Therefore, the limiting hole 51 can not only ensure that the movement and sliding of the bead are unrestricted, but also limit the bead as much as possible, so that when the bead reaches the drop hole, the bead hole can be aligned with the guide rod, which is convenient for bead passing.

[0036] To ensure smooth rotation of the drive component 5, the end face of the drive component 5 on the side that mates with the sliding surface 7 is provided with an inclined surface 10 that mates with the sliding surface 7. The inclined surface 10 is provided to prevent interference between the drive component and the sliding surface 7.

[0037] The drive structure 6 includes a drive motor 601 located at the upper end of the drive component 5 and a mounting bracket 602 for mounting the drive motor 601. The output shaft of the drive motor 601 is directly located at the center of the drive component 5, driving the drive component 5 to rotate.

[0038] The sliding surface 7 has corresponding grooves 11 at its inclined angles, located inside the conveying groove 1, to accommodate beads and mate with the sidewalls of the beads. The grooves 11 are provided to facilitate the smooth falling of the beads 14 onto the sliding surface; the grooves are arc-shaped, providing a certain buffering effect. The length of the sliding surface needs to be greater than the diameter of the beads; otherwise, the beads will get stuck in the output channel and cannot fall. Figure 7 In this state, the groove 11 provides a certain depth for the bead, allowing the bead 14 to completely detach from the conveying channel.

[0039] Preferably, the conveying groove 1 is a circular groove provided on the mounting plate 12; the bead drop hole 4 is provided with a guide rod 3 for threading beads; preferably, the conveying channel 2 is located on the side directly opposite the bead drop hole 4. The sliding surface near the conveying channel 2 has the largest inclination angle; preferably, the maximum inclination angle is 45 degrees. The sliding surface near the bead drop hole 4 is a plane, and the inclination angle gradually decreases from the sliding surface with the largest inclination angle to the sliding surfaces extending to both sides.

[0040] The conveying trough 1 is further provided with a climbing sliding surface 71 that mates with the sliding surface 7 from the drop hole 4 to the point where it mates with the conveying channel 2. The climbing sliding surface is located on the path of the drop hole 4 as it rotates with the drive component 5. The climbing sliding surface 71 can be a smooth sliding surface or several sliding surfaces connected in sequence for the beads to slide on. If the bead does not fall when it reaches the drop hole 4, the drive component 5 continues to push the bead to rotate. The bead climbs up through the climbing sliding surface 71 to the mating sliding surface 7 and rotates once more before falling again when it passes the drop hole.

[0041] The conveying channel 2 and the conveying trough 1 are mounted on the same mounting plate 12, and the guide rod 3 has a bead arranging structure 13 on one side. The bead arranging structure 13 can be based entirely on existing technology.

[0042] 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.
