Description

Technical Field

[0001] The present invention relates to the technical field of bead embroidery, and in particular to a bead conveying device that can be used for threading oriented beads. Background Art

[0002] Existing bead feeding devices include a cartridge for placing beads, a bead guiding rod for threading and feeding beads, and a bead feeding structure provided at the lower end of the bead guiding rod, etc. The upper end of the bead guiding rod is usually used for independently threading beads or cooperating with a bead threading device to thread beads, and after threading, it is conveyed downward. The upper end of the bead guiding rod can be directly placed inside the cartridge, and the beads rotate inside the cartridge and are threaded onto the bead guiding rod with a certain probability; alternatively, a bead conveying channel for conveying beads can be provided between the cartridge and the bead guiding rod to convey the beads to the bead guiding rod for threading. The above bead feeding devices cannot perform oriented bead threading for beads with different sides.

[0003] For a horizontally placed conveying channel, if the bead guiding rod is exactly located on one side of the conveying channel and the height of the upper end surface of the bead guiding rod is the same as the bottom surface of the conveying channel, then the beads move horizontally to the bead guiding rod. After the bead guiding rod is aligned with the bead hole, under the action of gravity, the beads can be threaded onto the bead guiding rod. However, for an inclined conveying channel or when the bottom surface of the conveying channel is much higher than the upper end surface of the bead guiding rod, the beads cannot fall smoothly into the bead guiding rod after coming out of the conveying channel, that is, it is difficult to align the bead hole with the bead guiding rod to complete bead threading. Therefore, there is an urgent need for a bead conveying device that can convey beads to the bead guiding rod to complete bead threading. Summary of the Invention

[0004] In order to solve the above problems of the prior art, the present invention provides a bead conveying device for bead embroidery with different sides, which can drive the beads to move from the conveying channel to the bead guiding rod for threading, and the beads move smoothly without being easily flipped or stuck.

[0005] The technical solution adopted is as follows:

[0006] A bead conveying device for bead embroidery includes a conveying bottom groove and an inclined bead conveying channel. The conveying channel is provided at the corresponding position of the conveying bottom groove. A bead dropping hole for cooperating with the bead guiding rod is provided on the bottom surface of the conveying bottom groove. A rotatable driving member is provided on the conveying bottom groove. The driving member is provided with a corresponding driving structure. At least one limiting hole for accommodating beads and pushing the beads to rotate in the conveying bottom groove is provided on the driving member. A smooth sliding surface or a plurality of sequentially connected sliding surfaces for the beads to slide are provided on the bottom surface of the conveying bottom groove between the conveying channel and the bead dropping hole. The sliding surface is provided with an inclined angle for receiving the beads output from the inclined channel at the position where it cooperates with the conveying channel. The inclined angle of the sliding surface gradually decreases to a plane from the corresponding position of the conveying channel to the bead dropping hole. At least before the beads enter the bead dropping hole, the sliding surface is a plane. The bead dropping hole and the conveying channel are at non - same working positions.

[0007] Furthermore, the driving member has a plurality of limiting holes arranged along the circumferential direction, and each limiting hole can accommodate a bead.

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

[0009] Furthermore, the end surface of the driving member on the side that cooperates with the sliding surface is provided with an inclined surface that cooperates with the sliding surface.

[0010] Furthermore, the driving structure includes a driving motor disposed at the upper end of the driving member and a mounting frame for mounting the driving motor.

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

[0012] Furthermore, the sliding surface has an inclined angle, and the corresponding position located on the inner side of the conveying bottom groove is provided with a groove for accommodating the beads and cooperating with the side wall of the beads.

[0013] Furthermore, the conveying channel is arranged on the opposite side of the bead dropping hole.

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

[0015] Furthermore, the conveying bottom groove is a circular groove arranged on the mounting plate; and a bead guide rod for threading beads is provided in the bead dropping hole.

[0016] Furthermore, the conveying bottom trough is also provided with a climbing sliding surface connected to the sliding surface from the bead falling hole to the cooperation with the conveying channel. The climbing sliding surface is located on the path of the bead falling hole rotating with the driving member. The climbing sliding surface is a smooth sliding surface or several sliding surfaces connected in sequence for the beads to slide.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention solves the problem that it is not easy to thread beads after the beads fall in the inclined conveying channel, and provides a bead conveying device for bead embroidery, which includes a conveying bottom groove. The conveying bottom groove is provided with a conveying channel and a bead dropping hole at non-identical working station positions. A driving member for driving the beads to rotate is provided at the upper end of the conveying bottom groove. At least one limiting hole is provided on the driving member, and each limiting hole can correspondingly accommodate one bead. A smooth sliding surface or a plurality of sliding surfaces connected in sequence for the beads to slide are provided on the bottom surface of the conveying bottom groove. From near the conveying channel to the bead dropping hole, the inclination angle of the sliding surface gradually becomes smaller. The beads fall from the conveying channel into the limiting holes, and under the drive of the driving member, they slide on the sliding surface, slide from the conveying channel to the bead dropping hole, and the inclination angle of the beads gradually becomes smaller, and finally becomes horizontal at the bead dropping hole, which enables the beads to slide smoothly and is not prone to flipping.

Detailed Embodiments

[0028] The following further describes the present invention in combination with specific embodiments.

[0029] Reference Figures 1-8 , a bead conveying device for bead embroidery, comprising a conveying bottom groove 1 and an inclined conveying channel 2 for beads 14. The upper end of the conveying channel 2 serves as a bead inlet and can be connected to a bead screening mechanism 15 for directionally outputting beads.

[0030] The described conveying channel 2 is provided at the corresponding position of the conveying bottom groove 1. A bead dropping hole 4 for cooperating with a bead guiding rod 3 is provided on the bottom surface of the conveying bottom groove 1, and the bead dropping hole 4 and the conveying channel 2 are not at the same working position. A rotatable driving member 5 is provided on the conveying bottom groove 1. The driving member 5 is provided with a corresponding driving structure 6. At least one limiting hole 51 for accommodating beads and pushing the beads to rotate in the conveying bottom groove 1 is provided on the driving member 5. A smooth sliding surface 7 or a plurality of sequentially connected sliding surfaces 7 for the beads to slide are provided on the bottom surface of the conveying bottom groove 1 between the conveying channel 2 and the bead dropping hole 4. The sliding surface 7 is provided with an inclination angle for receiving the beads output from the inclined channel at the position where it cooperates with the conveying channel 2. The inclination angle of the sliding surface 7 gradually decreases from the corresponding position of the conveying channel 2 to the bead dropping hole 4. At least before the beads enter the bead dropping hole 4, the sliding surface is a plane, and the plane and the inclined surface are relative. Preferably, for the convenience of threading the beads, this plane can usually be set as a horizontal plane, and of course, it can also be a plane with a slightly inclined angle.

[0031] Generally, the conveying channel 2 is connected to the bead screening mechanism 15. After being screened, the beads 14 enter the conveying channel and then fall into the conveying bottom groove 1 from the conveying channel 2. The driving member 5 drives the beads 14 to slide to the bead guiding rod 3 for threading. To ensure that the beads can be smoothly threaded into the bead guiding rod, the diameter of the bead dropping hole 4 needs to be greater than or equal to the diameter of the beads. Preferably, the diameter of the bead dropping hole 4 is greater than the diameter of the beads to ensure that the beads will definitely fall from the bead dropping hole 4. At least before the beads enter the bead dropping hole 4, the sliding surface is a plane, so that the beads remain horizontal before entering the bead dropping hole and there will be no phenomenon of stuck beads when entering the bead dropping hole, and the beads can fall into the bead guiding rod 3 under the action of gravity. If the beads 14 enter the bead dropping hole 4 obliquely, the bead holes of the beads will be difficult to align with the bead guiding rod, resulting in a stuck bead phenomenon.

[0032] The described conveying channel 2 is inclined and provided at the upper end of the conveying bottom groove 1, and the inclination angle of the conveying channel 2 is greater than or equal to the inclination angle of the sliding surface 7 close to the conveying channel. To enable the beads 14 to smoothly fall onto the sliding surface 7, the inclination angle of the conveying channel 2 is at least equal to the inclination angle of the sliding surface 7 close to the conveying channel. Preferably, it is 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 likely to flip when falling, making it difficult to ensure the front and back sides of the beads and affecting the subsequent sewing and embroidery effect.

[0033] The sliding surface 7 close to the conveying channel 2 is not made into a flat surface. Firstly, it is to prevent the beads from flipping. Secondly, it is to prevent the beads from getting stuck at the outlet of the conveying channel 2. If the sliding surface 7 is a flat surface, the conveying bottom groove 1 needs to be set with sufficient depth for the beads to fall. Otherwise, the beads will be stuck at the outlet and cannot come out. In this way, the beads have enough space to flip, and the falling height of the beads is too large, so the beads do not fall smoothly and are very easy to flip.

[0034] The inclination angle of the sliding surface 7 from the position corresponding to the conveying channel 2 to the sliding surface 7 at the bead dropping hole 4 gradually decreases, and can be transformed in advance or smoothly transformed into a horizontal plane. At least before the beads enter the bead dropping hole 4, the sliding surface is transformed into a horizontal plane. The gradually decreasing inclination angle enables the beads to move smoothly under the push of the driving member 5, and it is not easy to have the phenomenon of bead jamming. The adjacent sliding surfaces 7 are smoothly connected, which is convenient for the beads 14 to slide. The beads are gradually transformed from an inclined state to a horizontal state and pass through the bead dropping hole during movement.

[0035] Preferably, a plurality of limiting holes 51 cooperating with the beads are arranged circumferentially on the driving member 5. Each limiting hole 51 can accommodate one bead 14. When the limiting hole 51 is exactly aligned with the conveying channel 2, the beads fall into the limiting hole 51 and slide along with the rotation of the driving member 5. Arranging a plurality of limiting holes 51 can transport multiple beads at the same time, improving the efficiency. The side wall of the limiting hole 51 includes two side surfaces and a limiting surface 9, and one of the side surfaces forms a driving surface 8 along with the rotation of the driving member 5. When the driving member 5 rotates, the beads 14 are pushed to slide through the cooperation of the driving surface 8 and the beads 14.

[0036] The distance between the limiting surface 9 and the side wall of the conveying bottom groove 1 is adapted to the diameter of the conveyed beads, so as to be adapted to the corresponding width of the beads on the sliding surface 7 at different inclination angles. The width refers to the width of the projection of the beads towards the bottom surface. The limiting hole 51 is used to limit the beads 14 and drive the beads 14 to slide, and tries to ensure that the beads can accurately penetrate into the bead guiding rod. Therefore, the limiting hole 51 can not only ensure that the movement and sliding of the beads are not restricted, but also limit the beads as much as possible, so that when the beads reach the bead dropping hole, the bead holes can be aligned with the bead guiding rod, facilitating bead threading.

[0037] In order to ensure the smooth rotation of the driving member 5, a chamfer 10 cooperating with the sliding surface 7 is provided on the end surface of the driving member 5 on the side cooperating with the sliding surface 7. The chamfer 10 is provided to prevent interference between the driving member and the sliding surface 7.

[0038] The driving structure 6 includes a driving motor 601 provided at the upper end of the driving member 5 and a mounting bracket 602 for mounting the driving motor 601. The output shaft of the driving motor 601 is directly provided at the center of the driving member 5 to drive the driving member 5 to rotate.

[0039] The sliding surface 7 has a corresponding position on the inner side of the conveying bottom groove 1 where the sliding surface 7 has an inclined angle. The groove 11 is provided to accommodate the beads and cooperate with the side wall of the beads. The groove 11 is provided to facilitate the beads 14 to fall smoothly onto the sliding surface. The groove is an arc surface and plays a certain buffering role. The length of the sliding surface needs to be greater than the diameter of the beads, otherwise the beads will be stuck in the output channel and cannot fall down, for example Figure 7 The groove 11 provides a certain depth for the beads, so that the beads 14 are completely separated from the conveying channel.

[0040] Preferably, the conveying bottom groove 1 is a circular groove arranged on the mounting plate 12; the bead drop hole 4 is provided with a bead guide rod 3 for threading beads, and preferably, the conveying channel 2 is arranged on the opposite side of the bead drop hole 4. The inclination angle of the sliding surface close to the conveying channel 2 is the largest, and preferably, the largest inclination angle is 45 degrees. The sliding surface close to 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 surface extending to both sides.

[0041] The conveying bottom trough 1 is also provided with a climbing sliding surface 71 that docks with the sliding surface 7 from the bead dropping hole 4 to the place where it cooperates with the conveying channel 2. The climbing sliding surface is located on the path of the bead dropping hole 4 rotating with the driving member 5. The climbing sliding surface 71 is a smooth sliding surface or a plurality of sliding surfaces connected in sequence for the beads to slide. If the beads rotate to the bead dropping hole 4 without falling, the driving member 5 continues to push the beads to rotate, and the beads climb to the docking sliding surface 7 through the climbing sliding surface 71 and make another turn, and fall again when passing through the bead dropping hole.

[0042] The conveying channel 2 and the conveying bottom trough 1 are arranged on the same mounting plate 12, and a bead arranging structure 13 is arranged on one side of the bead guiding rod 3. The bead arranging structure 13 can completely adopt the existing technology.

[0043] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
