Description

Technical Field

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

[0002] The bead feed clamp mechanism is used in bead embroidery to transport beads at the bottom of the bead feed mechanism. Existing bead feed clamps consist of a bead clamp and a drive plate that propels the clamp forward and backward. The clamp typically clamps and advances or lags forward as the drive plate advances, and opens and retreats or lags backward as the drive plate retreats. To accurately control the clamping and opening of the bead clamp, ensuring more reliable clamping during bead feeding and placing beads into the needle's embroidery position, the clamp is typically equipped with a resistance-enhancing mechanism that lags its movement as it slides with the drive plate, enhancing the clamp's degree of clamping or opening.

[0003] The existing resistance-increasing structure is generally a magnet, which is set at the bottom of the base plate to adsorb the bead clip on the base plate. The magnet attracts and increases the resistance to the movement of the bead clip. While attracting the bead clip, the magnet also easily attracts the drive plate and other components around the bead clip, resulting in greater resistance to the sliding of the bead clip and the drive plate. The drive motor requires greater power when driving the bead clip to move, which increases the burden on the motor operation. Summary of the Invention

[0004] In order to solve the above problems of the prior art, the utility model provides a bead feeding clamp mechanism for feeding multiple beads, which only provides resistance for the bead clamp and does not affect other components, thereby reducing the burden on the motor.

[0005] The technical solutions adopted are as follows:

[0006] A bead feeding clamp mechanism for feeding multiple beads comprises a bead feeding base plate and at least two bead feeding clamp assemblies. The bead feeding base plate is provided with at least two conveying grooves that can guide the sliding bead feeding clamp assemblies. The bead feeding clamp assemblies include bead clamps and driving parts of the bead clamps. The bead feeding base plate is located on the sliding path of at least two of the bead feeding clamp assemblies and is provided with a resistance increasing structure that cooperates with the bead clamps and delays the bead clamps to slide with the driving parts to produce a clamping or opening action. A resistance column that cooperates with the resistance increasing structure is provided at the corresponding part of the bottom of the bead clamp. The resistance increasing structure is provided at the matching part of the bead feeding base plate and the bead clamp. The resistance increasing structure comprises a slide groove provided at the corresponding part of the bead feeding base plate for the resistance column to slide, and a pair of elastic resistance arms provided at corresponding positions on both sides of the slide groove to provide resistance for the resistance column. Each conveying groove is arranged centripetally toward the bead output end.

[0007] Furthermore, a movable groove is provided between the resistance arm and the bead feeding bottom plate.

[0008] Furthermore, the front ends of the pair of resistance arms are provided with a narrow opening that cooperates with the resistance column to delay the movement of the bead clamp with the driving member. The resistance arms are provided with inclined surfaces at both ends of the narrow opening that cooperate with the resistance column to delay the resistance column. The position of the narrow opening is such that when the driving member drives the bead clamp forward, at the latest before the clamping opening of the bead clamp is separated from the base plate, the resistance column on the bead clamp enters the narrow opening from the inclined surface at the corresponding end of the narrow opening; when the clamping opening of the bead clamp retreats from the bead embroidery position with the driving member, at the latest before the needle passes through the bead and hits the bead, the resistance column on the retreating bead clamp enters the narrow opening from the inclined surface at the other corresponding end of the narrow opening and retreats to cooperate with the narrow opening, so that the bead clamp lags behind the retreat of the driving member and quickly opens and releases the bead to the bead embroidery position.

[0009] Furthermore, the width of the narrow opening is smaller than the outer diameter of the resistance column.

[0010] Furthermore, the conveying trough and the bead clamp are provided with protrusions at corresponding positions, and the resistance-increasing structure is provided on the protrusions.

[0011] Furthermore, the conveying trough is provided with grooves on both sides of the protrusion.

[0012] Furthermore, each of the bead feeding clamp components corresponds to a driving structure.

[0013] Furthermore, the driving structure includes a driving motor, a synchronous pulley assembly, a driving member that drives the driving member to swing, and a driving rod that cooperates with the synchronous pulley assembly.

[0014] Furthermore, the bead feeding bottom plate is located at the outlet end of each bead feeding clamp assembly and is configured to be in a protruding cone shape.

[0015] Compared with the prior art, the beneficial effects produced by the present invention are:

[0016] The utility model provides a bead feeding clamp mechanism for feeding multiple beads, wherein at least two bead feeding assemblies are provided on a bead feeding base plate, and a resistance column is provided at the lower end of the bead clamp of each bead feeding assembly, and a resistance-increasing structure cooperating with the corresponding bead clamp is provided on the corresponding conveying groove of each bead feeding assembly, and the resistance-increasing structure includes a slide groove provided at a corresponding position of the bead feeding base plate for sliding the resistance column, and a pair of elastic resistance arms provided at corresponding positions on both sides of the slide groove to provide resistance for the resistance column. The resistance-increasing structure only generates resistance to the bead clamp, causing the bead clamp to lag relative to the driving member, thereby causing the driving member to drive the bead clamp to open or clamp, without affecting other components and without increasing the burden on the motor drive. In addition, the resistance-increasing structure is provided on the base plate, rather than on the upper end of the bead clamp, and only grooves need to be machined on the bead feeding base plate, saving space and materials. At the same time, each conveying groove is arranged centripetally toward the bead output end, which can facilitate each bead feeding clamp assembly to feed beads to the same machine needle without the need for an additional driving structure.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] refer to Figure 1-6 , a bead feeding clamp mechanism for feeding multiple beads, comprising a bead feeding base plate 1, at least two bead feeding clamp assemblies 2, the bead feeding base plate 1 is provided with a conveying groove 6 which can guide the sliding bead feeding clamp assembly 2 and can convey beads to the same machine needle, the bead feeding clamp assembly 2 comprises a bead clamp 201, a driving member 3 of the bead clamp, the sliding path of at least two of the bead feeding clamp assemblies 2 on the bead feeding base plate 1 is provided with a resistance increasing structure 4 which cooperates with the bead clamp and delays the bead clamp to slide with the driving member to produce a clamping or opening action, the corresponding part of the bottom of the bead clamp 201 is provided with a resistance increasing structure The resistance column 5 cooperates with the resistance structure 4, and the resistance-increasing structure 4 is arranged at the cooperation position of the bead feeding base plate and the bead clamp 201. The resistance-increasing structure 4 includes a slide groove 401 provided at the corresponding position of the bead feeding base plate for the resistance column 5 to slide, and a pair of elastic resistance arms 402 provided at corresponding positions on both sides of the slide groove to provide resistance for the resistance column. Each conveying groove 6 is arranged centripetally toward the bead output end, so that the multi-bead feeding mechanism of the utility model does not require other stroke driving structures, and beads can be fed to the same machine needle through multiple bead feeding clamp assemblies, which helps to simplify the product structure.

[0026] The structure in which the bead clamp 201 advances with a hysteresis as the driving member 3 advances and produces a clamping action, and retreats with a hysteresis as the driving member 3 retreats and produces an opening action can completely adopt the existing technical structure.

[0027] Preferably, a movable groove 12 for bending the resistance arm is provided between the resistance arm and the bead feeding bottom plate.

[0028] The front ends of the pair of resistance arms 402 are provided with a slot 9 that cooperates with the resistance column 5 to allow the hysteresis bead clip 201 to move with the driver 3. The resistance arms are provided with inclined surfaces 10 at both ends of the slot that cooperate with the resistance column 5 to delay the movement of the resistance column. The width of the slot 9 is set to be smaller than the diameter of the resistance column. When the resistance column 5 passes through, it provides resistance to the resistance column 5, moving the hysteresis bead clip 201, causing the bead clip 201 to lag behind the driver 3. The inclined surfaces 10 prevent the resistance column 5 from sliding unimpeded in other positions and also act as a buffer, guiding the resistance column 5 through the slot without damaging it.

[0029] Compared with the existing method of directly using magnetic attraction to provide resistance, the utility model does not affect other components. The resistance-increasing structure only provides resistance for the bead clip without increasing the burden on the drive motor.

[0030] The position of the narrow opening 9 satisfies the requirement that, at the latest when the clamping opening 202 of the bead clamp 201, which advances with the driver 3, completely slides out of the bead feeding base plate 1, the resistance post 5 of the advancing bead clamp 201 cooperates with the narrow opening 9, causing the bead clamp 201 to lag behind the advancement of the driver 3 and clamp to the front stop point, thus feeding the bead to the position where the needle can embroider the bead. Furthermore, when the driver 3 drives the bead clamp 201 forward to the front stop point, the resistance post 5 on the bead clamp 201 slides out from the inclined surface at the other end of the narrow opening, facilitating its retreat. At the latest before the needle passes through and strikes the bead, the clamping opening 202 of the bead clamp 201, which retreats with the driver 3 from the bead embroidery position, retreats to cooperate with the narrow opening 9, causing the bead clamp 201 to lag behind the retreat of the driver 3 and quickly unclamp and release the bead to the bead embroidery position.

[0031] The driving member 3 can be made of existing technology. In order to reduce the overall width of the bead clamp and adapt to the size of the multi-bead feeding base, the driving member 3 is preferably arranged at the lower end of the bead clamp. A matching finger groove and finger handle are provided between the driving member and the bead clamp.

[0032] Because the driver 3 is located at the lower end of the bead clamp 201, the conveying trough 6 is provided with a bump 7 corresponding to the bead clamp, and the resistance-enhancing structure 4 is located on the bump 7. The conveying trough is provided with grooves 11 on both sides of the bump 7. Grooves 11 can accommodate the driver 3 and allow it to slide. The resistance-enhancing structure 4 is located on the bump 7, and the resistance column 5 is located on the sliding surface between the bead clamp and the bump.

[0033] As another embodiment, the driving member is arranged on both sides of the bead clamp. In this case, there is no need to set up bumps and grooves. The bead clamp and the driving member both slide on the bead feeding bottom plate, and the resistance increasing structure can be directly arranged on the bead feeding bottom plate.

[0034] The resistance-increasing structure is directly arranged on the bead feeding bottom plate instead of the upper end of the bead clamp, saving space and materials.

[0035] Each of the bead feeding clamp components 2 corresponds to a driving structure 8. The driving motors corresponding to adjacent bead feeding components are arranged crosswise up and down.

[0036] The drive structure 8 includes a drive motor 801, a synchronous pulley assembly 802, and a drive rod 803 that cooperates with the synchronous pulley assembly to drive the swinging of the drive member 3. The drive motor 801 drives the swinging of the drive rod through the synchronous pulley assembly 802. The drive rod 803 is connected to the drive member 3, causing the drive member 3 to slide, thereby causing the bead clamp to slide.

[0037] The bead feeding base plate 1 is located at the outlet end of each bead feeding clamp assembly 2 and is set to a protruding cone shape, which can help extend the length of the bead feeding base plate at each conveying groove 6. When the bead clamp 201 of the bead feeding clamp assembly feeds beads to the machine needle, the bead clamp 2 supports the beads as much as possible by the base plate before moving forward to the machine needle to release the beads, preventing the beads from falling off unexpectedly before cooperating with the machine needle; at the same time, it makes the overall structure more compact and avoids interference with other mechanisms during the working process to the greatest extent.

[0038] 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.
