Description

Technical Field

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

[0002] The bead feed clamp structure consists of a bead clamp that slides to feed beads and a driver that propels the clamp forward, backward, and open / close. The clamp includes a pair of elastic clamping arms that cooperate and open / close. During bead feeding and retrieval, the clamping arms on either side of the clamp must repeatedly open and close. To facilitate the opening and closing of the elastic clamping arms, the conventional clamping arms are typically slender and thin, which can easily cause fatigue cracks in the slender connecting arms, leading to breakage at the weak points. As embroidery machine speeds continue to increase, the fatigue resistance of existing bead feed clamps will further decrease, rapidly shortening their lifespan. Utility Model Content

[0003] In order to solve the above problems of the prior art, the utility model provides a bead feeding clamp structure, which is not easy to break and prolongs the service life of the bead clamp.

[0004] The technical solutions adopted are as follows:

[0005] A bead feeding clamp structure includes a bead clamp body, wherein the bead clamp body is provided with clamping arms located on both sides and a central support plate, the clamping arms on both sides are provided with elastic arms connected to the bead clamp body, and the clamping arms on both sides are provided with thickened parts at least at the elastic arms.

[0006] Furthermore, a sink is formed between the thickened portions of the clamping arms on both sides, and a bead passing plate matched with the sink is provided in the sink.

[0007] Furthermore, the bead clamp body includes a base plate, and a wavy-curved unloading arm is provided between the base plate and the clamping arm, and the wavy-curved unloading arm constitutes all or part of the elastic arm.

[0008] Furthermore, the thickened portion is provided with parallel cut surfaces toward the sinking groove.

[0009] Furthermore, a driving member for driving the bead clamp body to advance, retreat, open and close is provided at the lower end of the bead clamp body.

[0010] Furthermore, the front ends of the clamping arms on both sides are provided with clamping openings, and the thickness of the clamping openings is smaller than the thickness of the elastic arms.

[0011] Furthermore, the tail connecting plate of the bead clip body is provided with an air-avoiding gap.

[0012] Furthermore, the bottom of the bead clip body is provided with a mounting countersunk hole for mounting the magnet and a stop pin.

[0013] Compared with the prior art, the beneficial effects produced by the present invention are:

[0014] The utility model provides a bead feeding clamp structure, comprising clamping arms provided on both sides of a bead clamp body, the clamping arms being connected to the bead clamp body via elastic arms. The base thickness of the bead clamp body remains constant, and thickened portions are provided at least at the elastic arms. A recessed groove is formed between the thickened portions for mounting a bead plate. The bead plate is disposed within the recessed groove without excessively increasing the thickness of the bead clamp body.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] refer to Figure 1-5 A bead feeding clamp structure includes a bead clamp body 1, the bead clamp body 1 being provided with clamping arms 101 on both sides and a central support plate 102. The clamping arms 101 on both sides are provided with elastic arms 5 connected to the bead clamp body 1, and the clamping arms 101 on both sides are provided with thickened portions 8 at least at the elastic arms. The thickened portions are provided where reciprocating elastic movement is required, which can effectively extend the life of the elastic arms 5. Referring to the accompanying drawings, as an option in this embodiment, the outer portions of the clamping arms 101 on both sides and the elastic arms 5 can be provided with thickened portions 8.

[0022] Providing a thickened portion 8 where reciprocating elastic activity is required can increase the rigidity of the clamp and improve the fatigue resistance of the bead feeding clamp. During the repeated opening and closing of the bead clamp, the weak parts of the clamping arm are thickened, which increases the rigidity and makes it less likely to break, thereby increasing and improving the service life of the bead clamp.

[0023] A recessed groove 6 is formed between the thickened portions of the clamping arms 101 and the central support plate 102. This recessed groove 6 accommodates the bead plate, which is then positioned within the recessed groove 6. The base plate 3 of the bead clamp body 1 maintains a constant thickness, while the recessed groove 6 formed in the center of the thickened portion 8 serves as the mounting groove for the bead plate. The bead plate 2 is positioned within the recessed groove 6 between the thickened portions, without protruding outward and thus not excessively increasing the thickness of the bead clamp.

[0024] The bead clamp body 1 includes a base plate 3 . A wavy unloading arm 9 is provided between the base plate 3 and the clamping arm 101 . The wavy unloading arm 9 constitutes all or part of the elastic arm 5 .

[0025] When the clamping arm 101 is elastically deformed, the stress is mainly concentrated at the connection between the unloading arm 9 and the base plate 3, so the thickened portion is provided on the elastic arm 5, including the unloading arm portion. The overall elastic deformation of the wavy unloading arm 9 can be used to buffer and effectively disperse stress. At the same time, increasing the thickness can further increase the rigidity of the unloading arm 9, avoiding stress concentration in weak spots and causing the bead clamp to break. In addition, the wavy unloading arm 9 reduces the rigidity per unit area and improves the flexibility of the entire unloading arm 9, so that when clamping beads of different sizes, the clamping elasticity of the clamping mouth 103 is softer, so that the clamping force is more evenly distributed on the entire unloading arm 9, and the deformation of the unloading arm 9 is relatively more uniform.

[0026] The thickened portion 8 is provided with parallel cut surfaces 7 in the direction of the sink. In this embodiment, the thickened portion is provided on a portion of the clamping arm 101. The parallel cut surfaces are provided to facilitate processing. The sink can be cut directly in the middle of the bead feeding clamp, and the two sides of the sink are parallel cut surfaces. There is no need to cut the sink according to the shape of the clamping arm of the bead feeding clamp, which makes processing simpler and faster, saving time and cost.

[0027] The lower end of the bead clamp body 1 is provided with a driving member 2 for driving the bead clamp body 1 to advance, retreat and open and close.

[0028] The front ends of the clamping arms 101 on both sides are provided with clamping openings 103. The thickness of the clamping openings 103 is less than that of the elastic arms 5. The clamping openings 103 are used to clamp and deliver beads. They should not be too thick, as this would affect bead delivery. The clamping openings 103 are generally consistent in thickness with the central support plate 102.

[0029] The driving structure of the substrate 3, clamping arm 101, driving member 2, and other structures can adopt the existing technical structure. The convex column or convex finger is set on the driving member 2, and the control groove is set on the bead clamp body 1 to cooperate with the convex column or convex finger to drive the bead feeding clamp forward and backward, and control the clamping arm to clamp the clamping mouth of the bead clamp to deliver the beads when it moves forward, and control the clamping arm to open the clamping mouth of the bead clamp to receive the beads when it moves backward.

[0030] The tail connecting plate of the bead clamp body 1 is provided with an air-avoidance gap 4. The air-avoidance gap 4 is provided on the tail connecting plate to facilitate the disassembly of the bead clamp body 1 and the bead clamp driving component 2, and to avoid interference between the bead clamp body 1 and the connecting rod driving the bead clamp driving component 2. The air-avoidance gap 4 can be set to a required shape according to actual conditions. In this embodiment, it can be set to an arc-shaped air-avoidance gap.

[0031] The bottom of the bead clamp body 1 is equipped with a mounting countersunk hole 10 for the magnet and a stop pin 11. Once the magnet is installed, the magnet and the bead feeding base plate create magnetic attraction resistance, allowing the bead clamp body 1 to lag behind the movement of the driver 2, completing the bead clamping and receiving action. The stop pin 11 engages with a sliding groove on the base plate to limit the range of movement of the bead clamp body 1. The above structure can be referenced to existing technologies.

[0032] 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.
