Description

Technical Field

[0001] This utility model relates to the field of bead embroidery technology, and in particular to a bead feeding mechanism for bead embroidery. Background Technology

[0002] Bead embroidery typically includes a bead feeding mechanism to transport beads from a guide rod to the work position for beading. This mechanism generally includes a feeding base plate, a bead clamp that slides on the base plate, and a drive mechanism. The drive mechanism moves the bead clamp, clamps the beads, and releases them. Beads come in various shapes and sizes; some are regular cylinders with a cylindrical outer surface, while others have a conical top and a cylindrical bottom. The bead clamp consists of a pair of clamping arms with a jaw at the front. The jaw has a groove on its inner side that mates with the bead. The bead falls into the groove, and the inner wall of the clamping arm contacts the outer wall of the bead, clamping it. If the cylindrical outer wall of the bead is very thin, the contact area between the bead and the clamping arm is too small. During clamping, the bead can easily slip and break out, affecting subsequent sewing. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a bead feeding mechanism for bead embroidery, suitable for thin beads, which securely clamps and places beads, preventing beads from slipping or falling out.

[0004] The technical solution adopted is as follows:

[0005] A bead feeding mechanism for bead embroidery includes a bead feeding base plate, a bead clamp sliding on the bead feeding base plate, and a driving component for driving the bead clamp to feed beads. The bead clamp includes two elastic clamping arms, each with a clamping opening at its front end. Both clamping arms have grooves on their side walls at the clamping openings that can mate with beads. Both clamping arms have downwardly extending thickened portions at the grooves. The bead feeding base plate has a bead-receiving base surface at the bead-dropping point for receiving beads. On both sides of the bead-receiving base surface, there is a recessed groove that mates with the thickened portion of the corresponding clamping arm. The grooves are partially or entirely located above the bead-receiving base surface.

[0006] Furthermore, the height of the bead-receiving base surface is greater than or equal to the height of the bottom surface inside the groove.

[0007] Furthermore, the aforementioned bead clip is suitable for thin beads or flat-bottomed beads with different surfaces.

[0008] Furthermore, the height of the bead or the height of the bead's cylindrical surface is less than the height of the groove opening.

[0009] Furthermore, a mounting base is provided on one side of the bead feeding base plate, and the mounting base is provided with a driving structure for driving the bead clamp to clamp and feed the beads.

[0010] Furthermore, the drive structure includes a drive motor, a drive arm, and a synchronous pulley assembly disposed between the drive motor and the drive arm.

[0011] Furthermore, the upper end of the receiving base is provided with a drop block, and the drop block is provided with a drop hole, which is correspondingly set with the guide rod.

[0012] Furthermore, the receiving base surface is flush with the sliding surface of the bead clamp located on the bead feeding base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention provides a bead feeding mechanism for bead embroidery. A groove is provided on the side wall of the clamping arm at the clamping opening to accommodate and support the bottom of the bead. A thickened portion extends downward from the clamping arm at the groove. A corresponding bead-receiving base surface is provided at the lower end of the bead clamp for bead dropping. The receiving base surface has recessed grooves on both sides that mate with the thickened portion. The groove is partially or entirely located above the receiving base surface. The bead falls from the drop hole onto the receiving base surface, and then the bead clamping arm holds the bead. Because of the groove on the side of the clamping arm, the bead will partially engage with the groove, which supports the bottom of the bead, making the bead feeding and clamping more stable and preventing the bead from popping out. This invention is applicable to thin beads or flat-bottomed beads with a conical upper end and a cylindrical lower end. Attached Figure Description

[0017] Figure 3 , 4 These are schematic diagrams of the partial structure of this utility model from two different angles;

[0018] Among them, there are: bead feeding base plate 1, bead clamp 2, clamping arm 201, driving component 3, clamping mouth 4, thickened part 5, groove 6, inner bottom surface 61, bead receiving base surface 7, mounting base 8, driving structure 9, driving motor 901, driving arm 902, synchronous belt pulley assembly 903, bead dropping block 10, bead 11, and sinking groove 12. Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] refer to Figure 1-4A bead feeding mechanism for bead embroidery includes a bead feeding base plate 1, a bead clamp 2 that slides on the bead feeding base plate 1, and a driving component 3 that drives the bead clamp to feed beads. The bead clamp 2 includes two elastic clamping arms 201. The front end of the clamping arm 201 is provided with a clamping opening 4. The side wall of the two clamping arms 201 at the clamping opening 4 is provided with a groove 6 that cooperates with the bead. The two clamping arms 201 at the groove 6 are provided with a downwardly extending thickened part 5. The groove 6 can cooperate with the bead 11 to clamp the bead and can support the bottom surface of the bead, clamping the bead in the clamping opening 4 through the groove 6.

[0021] The ball-feeding base plate 1 has a ball-receiving base 7 at the ball-dropping point. On both sides of the ball-receiving base 7, there is a recessed groove 12 that matches the thickened part 5 of the corresponding clamping arm. The groove 6 is partially or entirely located above the ball-receiving base 7.

[0022] For ease of manufacturing, the bead receiving base surface 7 is flush with the sliding surface of the bead clamp 2 on the bead feeding base plate 1.

[0023] The bead clip 2 is suitable for thin beads or non-flat bottom beads. Non-flat bottom beads refer to beads whose bottom diameter is larger than the top diameter. The outer wall of the bead includes a conical surface at the top and a cylindrical surface at the bottom. In this embodiment, the bead is a non-flat bottom bead, and the height of the cylindrical surface is relatively small.

[0024] If the beads are thin, they are prone to breakage when clamping due to the small contact area between the beads and the clamping arm 201. The groove 6 is designed so that when the bead clamp 2 clamps the beads, part of the beads can be inserted into the groove 6. The bottom of the groove 6 can support the bottom of the beads, making it less likely for the beads 11 to fall out of the bead clamp 2. The bead clamp makes the movement of the beads 11 and the placement of the beads more stable, which is convenient for subsequent sewing and embroidery.

[0025] The thickened portion and the recessed groove 12 are provided to ensure that the height of the bead-receiving base 7 is greater than or equal to the height of the bottom surface of the groove 6. When the bead 11 is dropped, it first lands on the bead-receiving base 7, and then the bead clamp moves to the bead-receiving base to clamp the bead. Therefore, in order for the bead to be able to quickly and successfully be inserted into the groove 6, it is preferable that the height of the bottom surface of the groove 6 be less than or equal to the height of the bead-receiving base 7, so that the bottom surface of the groove 6 can support the bottom of the bead. In order for the bead 11 to be inserted into the groove 6, the height of the bead 11 or the height of the cylindrical surface of the bead should also be less than the height of the groove opening of the groove 6. For bead with a flat bottom and non-circular surface, the cylindrical part of the bead 11 is inserted into the groove 6, and the clamping arm 201 clamps the conical part of the bead 11.

[0026] The ball-feeding base plate 1 has a mounting seat 8 on one side, and the mounting seat 8 has a driving structure 9 for clamping and feeding balls using the ball clamp 2. The driving structure 9 includes a drive motor 901, a drive arm 902, and a synchronous pulley assembly 903 located between the drive motor 901 and the drive arm 902. The drive motor 901 drives the drive arm 902 to swing through the synchronous pulley assembly 903. The swinging of the drive arm 902 causes the drive component 3 to slide on the base plate. The drive component 3 can drive the ball clamp 2 to slide and can also drive the clamping arm 201 of the ball clamp 2 to open and close. The structure and principle can be completely referred to the prior art.

[0027] The upper end of the bead receiving base 7 is provided with a bead dropping block 10, and the bead dropping block 10 is provided with a bead dropping hole, which is correspondingly set with the bead guide rod. The bead falls from the bead guide rod into the bead dropping hole, is guided by the bead dropping block 10 and falls onto the bead receiving base 7, and is then clamped by the bead clamp.

[0028] 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.
