[0025] See also Figures 1 to 5 As shown, according to an embodiment of the utility model, a bead feeding device for an embroidery machine is provided, comprising a base plate 1, and vertical walls are arranged relatively along the length direction of the base plate 1. In the extension direction of the vertical walls, the base plate gradually narrows from a preset position, and the narrowing angle α is 5° to 20°. Compared with the traditional base plate, the present application adjusts the base plate structure, and gradually narrows at a preset position of the vertical wall of the base plate 1. The preset position can be one end of the base plate, the 1 / 3 position of the base plate, or any other position in the length direction of the base plate. This structural setting can release more installation space, but of course the structure cannot be extended indefinitely. Since the base plate 1 is a carrier for the bead clamping plate, the structure of the base plate will determine the structure of the bead clamping plate 2 installed thereon, and the bead clamping plate still needs to meet the requirements of bead clamping strength and stability. Therefore, the angle between the narrowing direction and the axis, that is, the narrowing angle α is set to 5° to 20°, which can not only ensure the release of more installation space, but also effectively ensure the stability of the bead clamping plate 2.

[0026] In a specific embodiment, the bead feeding device of the bead embroidery machine also includes a bead clamping plate 2, wherein the bead clamping plate 2 has two clamping arms 202, one end of the clamping arm 202 is a free end, and the other end is a U-shaped elastic end, and the bead clamping plate 2 has an avoidance groove 201 at the arc section close to the U-shaped elastic end. During the bead clamping process of the bead clamping plate 2, the two clamping arms 202 have an unfolded state and a clamped state. When the clamping arm 202 is in the unfolded state, the U-shaped bottom end position will approach the wall surface adjacent to it under the action of force. The avoidance groove 201 is set at this position, which can increase the unfolding range of the clamping arm 202 and improve the bead clamping effect.

[0027] Specifically, the avoidance groove 201 may also be directly opened at the arc section of the U-shaped elastic end.

[0028] In a specific embodiment, the other end of the clamp arm 202 has an arc groove, and two oppositely arranged arc grooves form a bead clamping hole 203. The arc groove structure can increase the contact area between the clamp arm and the bead, making the bead clamping and feeding process more stable and avoiding the risk of bead falling.

[0029] In a specific embodiment, the bead plate 2 has a magnet mounting hole on one side close to the base plate 1, and the inner peripheral wall of the magnet mounting hole has an annular boss. The annular boss is provided to divide the magnet mounting hole into an upper hole and a lower hole, the upper hole is used to place the magnet, and the lower hole is used to inject adhesive material, so that more adhesive material is retained in the mounting hole, which can make the magnet bond more firmly and stably, and effectively avoid the risk of the magnet falling. Preferably, the adhesive material is glue.

[0030] In a specific embodiment, the bottom plate 1 has a limiting mechanism 102 in the length direction, and the bead clamping plate 2 has a first limiting column 204 on the side close to the bottom plate 1, and the first limiting column 204 is adapted to the limiting mechanism 102 so that the first limiting column 204 can slide in the limiting mechanism 102. Adapting the size of the limiting mechanism 102 and the first limiting column 204 can not only meet the sliding of the first limiting column 204 in the limiting mechanism 102, but also effectively prevent the beads from accidentally falling into the slideway, causing the phenomenon of bead delivery jamming. At the same time, the contact area of ​​the magnet at the bottom of the bottom plate 1 on both sides of the limiting mechanism 102 can be increased, and the magnetic force can be enhanced, so that the bead clamping plate 2 can slide more stably on the bottom plate 1. The limiting mechanism 102 is set at a suitable length. When the first limiting column 204 contacts the two ends of the limiting mechanism, the movement of the bead clamping plate can be effectively blocked. The bead clamping plate 2 is limited to the bead taking position and the bead delivery position.

[0031] In a specific embodiment, the limiting mechanism 102 is a limiting hole or a limiting groove.

[0032] In a specific embodiment, the bead feeding device of the embroidery machine also includes a guide device 4, the guide device 4 includes a rocker seat 401, a guide arm 402 connected to one end of the rocker seat 401, and the end of the guide arm 402 away from the rocker seat 401 has a second limiting column 403, and the guide arm 402 is adapted to the groove 101 of the base plate 1 so as to be able to slide in the groove. The bead clamping plate 2 and the guide device 4 are separately arranged, which is convenient for installation and maintenance, and the structure is simple and easy to maintain. Two second limiting columns 403 are provided, which can realize the action of clamping and releasing beads, and the two second limiting columns 403 cooperate with the first limiting column to realize three-point positioning, so that the bead clamping plate 2 is more stable in the bead clamping position and the bead feeding position.

[0033] In a specific embodiment, the bead feeding device of the embroidery machine further includes a limit block 6, the swing rod seat 401 has a first vertical wall and a second vertical wall arranged at intervals, the limit block 6 is located directly above the first vertical wall, and the limit block 6 is matched with the top wall gap of the first vertical wall. The limit block 6 is fixedly mounted on the connecting plate 5 of the bottom plate 1 and matched with the first vertical wall gap of the guide device, so that the swing rod seat 401 can be better limited to prevent the guide device 4 from leaving the running track during operation.

[0034] In a specific embodiment, the bead feeding device of the bead embroidery machine also includes a U-shaped receiving plate 3, and the receiving plate 3 is located at the front end of the base plate 1. The receiving plate is provided with a through hole, and the through hole is arranged corresponding to the bead clamping hole of the bead clamping plate 2. The traditional receiving plate 3 is L-shaped and fixed on one side, which requires sufficient installation space on one side, and the strength requirement of the receiving plate 3 is high, the corresponding size is large, and the floor space is large after installation. The present application adopts a U-shaped receiving plate 3, which is fixed on both sides, or fixed on one side. The double-sided fixation improves the stability, can reduce the size requirements of the receiving plate 3, and saves installation space. The receiving plate 3 with a U-shaped structure can play a better protective role at the front end to prevent the front end of the bead clamping plate 2 from tilting during the movement of the bead clamping plate 2.

[0035] In a specific embodiment, the narrowing angle α is 10° to 15°. Preferably, the narrowing angle is 13°. When the narrowing angle is 13°, when the bead feeding distance is met, the end of the bottom plate is triangular, which has the advantages of beautiful shape, convenient processing and low cost compared to bottom plates of other shapes.
