Description

Technical Field

[0001] The utility model relates to the technical field of bead embroidery, in particular to a bead feeding clamp mechanism. Background Art

[0002] The bead feeding clamp structure includes a bead clamp that slides to feed beads, a driving member that drives the bead clamp to advance and retreat and open and close, and a cover plate provided at the upper end of the bead clamp. The bead clamp includes a pair of elastic clamping arms that can cooperate to open and close, and a driving structure is provided between the driving member and the elastic clamping arms. Most of the existing driving structures are control finger handles and driving finger grooves that cooperate with the corresponding parts of the driving member and the elastic clamping arm, wherein the control finger handle is generally provided on the driving member and the driving finger groove is provided on the clamping arm.

[0003] An existing driving component includes a pair of driving plates arranged on both sides of the bead feeding clamp, and the control finger handle is arranged on the driving plate and is arranged toward the clamping arm. The driving plates are arranged on both sides of the bead feeding clamp, which increases the width of the bead feeding clamp structure to a certain extent, occupies space, is not conducive to the design of a multi-bead feeding clamp, and is not suitable for a smaller head-to-head distance.

[0004] To reduce size, a drive element has been designed. The drive plate is directly mounted on the top or bottom of the clamping arm. The drive plate has a bump that acts as a control crank and cooperates with the drive finger groove on the clamping arm. This design does not take up space on either side of the bead feeding clamp or increase the width of the bead feeding clamp structure. However, due to the certain thickness of the drive plate, mounting it on the top or bottom of the clamping arm will increase the thickness of the bead feeding clamp structure. Too much thickness will affect the bead feeding clamp's ability to grip beads. Summary of the Invention

[0005] In order to solve the above-mentioned problems of the prior art, the utility model provides a bead feeding clamp mechanism that completes driving without increasing the width or thickness, and has a smaller size than the prior art.

[0006] The technical solutions adopted are as follows:

[0007] A bead feeding clamp mechanism comprises a bead feeding base plate, a bead feeding clamp sliding on the bead feeding base plate, and a driving member driving the bead feeding clamp to advance, retreat and open and close, the bead feeding clamp comprising a pair of elastic clamping arms that can be opened and closed, the clamping arms comprising an elastic portion and a clamping portion, a first slide groove being provided between the pair of clamping arms, the first slide groove being provided between the elastic portions, or between the elastic portion and part of the clamping portion, the driving member comprising a driving plate provided in the first slide groove and cooperating with the first slide groove, a control structure being provided between the clamping arm and the driving plate so as to advance and clamp, or to lag behind and clamp when advancing, to retreat and open, or to lag behind and retreat and open when retreating.

[0009] Furthermore, the driving block includes a pair of control finger handles extending to both sides, and the driving groove is provided with a driving finger groove matching with the control finger handles.

[0010] Furthermore, the control finger handle is provided with an extension plate extending outwardly toward the clamping portion, and the driving groove is provided with a sink groove matching the extension plate.

[0011] Furthermore, the driving finger groove is provided with a first inclined surface that cooperates with the control finger handle and enables the control finger handle to drive the clamping arm to clamp; the driving finger groove is also provided with a second inclined surface that cooperates with the control finger handle and enables the control finger handle to drive the clamping arm to open.

[0012] Furthermore, a resistance-increasing structure is provided on the sliding path of the bead clamp, which cooperates with the bead clamp and delays the bead clamp from sliding with the driving member to produce a clamping or opening action.

[0013] Furthermore, the resistance increasing structure is a magnet provided on the bead feeding clamp.

[0014] Furthermore, the bead feeding base plate is provided with a second sliding groove for the bead feeding clamp and the driving member to slide, and a pair of limiting grooves are provided on both sides of the second sliding groove to limit the sliding range of the bead feeding clamp, and the bead feeding clamp is provided with a limiting block that cooperates with the limiting groove.

[0019] The driving plate is directly arranged in the driving groove provided in the middle of the clamping arm and does not protrude outward, which neither increases the width of both sides of the clamping arm nor increases the overall thickness of the bead feeding clamp. Therefore, the size of the bead feeding clamp is smaller than that of the bead clamp in the prior art. At the same time, the bead feeding base plate can also be reduced in size, which is suitable for bead embroidery machines with multiple beads and small head distance.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific implementation methods.

[0027] refer to Figure 1-6A bead feeding clamp mechanism includes a bead feeding base plate 1, a bead feeding clamp 2 that slides on the bead feeding base plate 1, and a driving member 3 that drives the bead feeding clamp 2 to advance, retreat, and open and close. The bead feeding clamp 2 includes a pair of elastic clamping arms 201 that can be opened and closed. The clamping arms 201 include an elastic portion 2012 and a clamping portion 2011. A first slide 4 is provided between the pair of clamping arms 201. The first slide 4 is provided between the elastic portion 2012 or between the elastic portion and a portion of the clamping portion. The driving member 3 includes a driving plate 301 disposed within and cooperating with the first slide. A control structure 6 is provided between the clamping arms 201 and the driving plate 301 to enable the clamping arms 201 to advance and clamp as the driving plate 301 advances, or to lag behind and clamp as the driving plate 301 advances; to retract and open as the driving plate 301 retracts, or to lag behind and open as the driving plate 301 retracts. Whether the clamping arms 201 are synchronized or lagged with the driving plate 301 can be determined based on the specific structure.

[0028] The control structure 6 includes a driving groove 601 provided at one end of the first sliding groove 4 close to the clamping portion, and a driving block 602 is provided on the driving plate 301 to cooperate with the driving groove 601 .

[0029] A first slide groove 4 is provided in the middle of the clamping arm 201, and the driving member 3 is provided in the first slide groove 4. Compared with the bead feeding clamp mechanism in the prior art in which the driving members are provided on both sides of the clamping arm 201, the bead feeding clamp mechanism of the utility model omits the width of the driving member, and the size can be made smaller, thereby reducing the overall width of the bead feeding clamp mechanism, so that the bead feeding base plate can be made as narrow as possible, reducing the occupied space, and is suitable for embroidery machines with multiple bead feeding pieces and small head distance.

[0030] The driving member 3 is installed in the first slide groove 4, and will not protrude outward, and will not increase the overall thickness of the bead feeding clamp. Compared with the bead feeding clamp mechanism in the prior art in which the driving plate is arranged at the bottom of the bead feeding clamp, the thickness of the present invention is smaller, and there is a certain space between the bead feeding clamp and the bead guide block, so that the bead feeding clamp can release beads more smoothly.

[0031] The drive block 602 includes a pair of control fingers 6021 extending toward each side, forming an angle between the pair of control fingers 6021. The drive slot 601 is provided with a drive finger slot 5 that cooperates with the control fingers. The drive finger slot 5 includes a first inclined surface 501 that cooperates with the control fingers to enable the control fingers to drive the clamping arm 201 to clamp. The drive finger slot 5 also includes a second inclined surface 502 that cooperates with the control fingers to enable the control fingers to drive the clamping arm 201 to expand.

[0032] The maximum width of the driving block 602 at the control finger handle 6021 is greater than the width of the first slide groove 4. Therefore, when the driving block drives the bead feeding clamp 2 to retreat, the bead feeding clamp 2 lags behind the driving block 602, and the control finger handle 601 cooperates with the second inclined surface 502 to squeeze the clamping arm 201, causing the clamping arm 201 to open. When the driving block 6 drives the bead feeding clamp 2 forward, the bead feeding clamp 2 lags behind the driving block 602, and the control finger handle 6021 cooperates with the first inclined surface 501 to push the clamping arm 201 forward, causing the clamping arm 201 to clamp.

[0033] The control finger handle 6021 is also equipped with an extension plate 17 extending outward toward the clamping portion. The drive slot is also equipped with a recessed groove 18 that mates with the extension plate 17. The extension plate 17 increases the overall size of the drive block 6, enhancing its rigidity and making it less susceptible to breakage, particularly in the thinner and narrower areas of the control finger handle 6021. The recessed groove 18 in the drive slot allows the drive plate 301 to fit snugly within it, without increasing the overall thickness of the bead feed clamp.

[0034] The bead feeding clamp 2 is provided with a resistance-enhancing structure 8 in its sliding path. This structure cooperates with the bead feeding clamp and delays the clamp's clamping or opening motion as the driver slides. The resistance-enhancing structure 8 is designed to cause the bead feeding clamp to lag its motion relative to the driver, thereby driving the clamping arm to clamp or open, facilitating bead feeding. In this embodiment, the resistance-enhancing structure 8 is a magnet mounted on the bead feeding clamp 2.

[0035] The bead feeding base plate 1 is provided with a second chute 13 for sliding the bead feeding clamp 2 and the driving member. A pair of limit grooves 14 are provided on both sides of the second chute 13 to limit the sliding range of the bead feeding clamp 2. The bead feeding clamp 2 is provided with a limit block 15 that cooperates with the limit grooves 14. The limit grooves 14 limit the movement range of the bead feeding clamp 2, making it easier for the bead feeding clamp 2 to accurately clamp and release beads.

[0036] The bead feeding base plate 1 has a third chute 9 located below the second chute 13, through which the driving member slides. The driving plate 301 has a slider 10 on its underside, which engages with the third chute. The third chute 9 and slider 10 facilitate the sliding movement of the driving plate 301. When the bead feeding clamp 2 is restrained from moving backward by the stop slot 14, the driving plate 301 can still slide backward.

[0037] The driving mechanism further includes a driving assembly 7 for driving the driving member 3 to slide. The driving assembly 7 includes a driving motor 701, a synchronous pulley assembly 702, a connecting rod 703, and a driving block 704 connected to the driving member 3. The driving motor 701 drives the connecting rod 703 to swing through the synchronous pulley assembly 702. One end of the connecting rod is connected to the connecting block 704, which can drive the connecting block 704 to slide, thereby driving the driving member 3 to slide.

[0038] The bead feeding bottom plate 1 is provided with a mounting seat 11 for mounting the driving assembly 7. A bead guide block 16 is provided on the mounting seat at a corresponding position on the upper end of the bead feeding bottom plate 1.

[0039] The upper end of the bead feeding clamp 2 is provided with a cover plate 12. It is used to block the beads and reduce the wear of the beads.

[0040] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
