Description

Technical Field

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

[0002] Bead embroidery devices typically include a bead guide rod. This rod is used to thread and guide the beads along its length to the receiving position of the bead feeding mechanism. The bead clamp then picks up the bead from the receiving position and feeds it directly below the needle. The bead guide rod is generally a long, straight steel wire. It is usually designed to be relatively thin for several reasons: first, to ensure versatility; second, to allow the beads to fall smoothly to the receiving position, reducing friction between the bead and the bead's inner hole, allowing the beads to fall quickly and smoothly under gravity without getting stuck; and third, to reduce the rigidity of the bead guide rod. Guide rods typically require rollers or clamps for fixation and positioning. For example, after the guide rod exits the barrel, several clamps are located on one side to hold it in place. During this clamping process, the guide rod can easily wobble, causing its output end to deviate from its original position. This prevents the bead from passing smoothly through the guide hole in the guide sleeve, potentially causing it to get stuck at the top of the guide post hole, affecting bead feeding. Using a thinner guide rod with lower rigidity means that even if the clamped position is slightly off, it won't easily affect the position of the guide rod at the output end, making it easier for the bead to pass through the guide hole.

[0003] However, the inner diameter of the bead is relatively large compared to the outer diameter of the thinner guide rod. This makes it easy for the bead to wobble, tilt, or even get stuck in the entrance or hole of the guide sleeve when it falls at the end of the guide rod. When the bead clamp opens to receive the bead, the bead will tilt, causing the bead to leak or fly away, affecting the sewing of the beads and causing waste. Utility Model Content

[0004] To address the problems of the prior art, this invention provides a bead guide rod for bead embroidery. The end of the bead guide rod is thickened to maintain a good fit between the bead guide rod and the inner hole of the bead, resulting in a more stable drop of the bead and a better embroidery effect.

[0005] The technical solution adopted is as follows:

[0006] A bead guide rod for bead embroidery includes a bead guide rod body, wherein the output end of the bead guide rod body is provided with a thickened portion, the diameter of which is larger than the diameter of the bead guide rod body.

[0007] Furthermore, the height of the thickened portion is greater than or equal to the height of the beads conveyed by the guide rod body.

[0008] Furthermore, a transition section for guidance and transition is provided between the thickened part and the guide rod body.

[0009] Furthermore, the outer surface of the transition section is a smooth, tapered transition surface.

[0010] Furthermore, the thickened portion and the transition section can be integrated into a single unit, forming a sleeve fitted over the body of the guide bead rod.

[0011] Furthermore, the thickened portion and the transition section can be set separately and sequentially fitted onto the outside of the guide rod body.

[0012] Furthermore, the thickened portion is concentrically arranged with the guide bead rod body.

[0013] A bead guide rod for bead embroidery includes a bead guide rod body. The output end of the bead guide rod body is provided with a guide post. The guide post includes a cylinder at the lower end and a conical column at the upper end for connecting to the bead guide rod body. The diameter of the cylinder is larger than the diameter of the bead guide rod body. The upper end of the conical column is a small-diameter end. The diameter of the small-diameter end where it connects with the bead guide rod body is less than or equal to the diameter of the bead guide rod body. The end face of the small-diameter end of the conical column does not extend beyond the end face of the bead guide rod body at the point where it connects with the bead guide rod body.

[0014] Furthermore, the guide post is welded, bonded, or interference-fitted to the guide ball rod body.

[0015] Furthermore, a connecting structure is provided between the guide post and the guide ball rod body.

[0016] Furthermore, the connection structure includes a connecting rod located at the lower end of the guide bead rod body and a connecting hole located on the guide post that mates with the connecting rod;

[0017] Furthermore, the connection structure includes a connection hole at the lower end of the guide bead rod body and a connection rod at the upper end of the guide post that mates with the connection hole.

[0018] Furthermore, the guide bead rod body is concentrically arranged with the cylindrical or conical guide post.

[0019] Furthermore, the cylindrical and conical cylinders are arranged concentrically.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention provides a bead guide rod for bead embroidery. The output end of the guide rod has a thickened section located at the bead drop point. The diameter of the thickened section matches the inner diameter of the bead, allowing for more accurate bead positioning when the bead falls to the drop point. The inner diameter of the bead fits better with the guide rod, preventing it from tilting or slipping to one side. When the bead clamp is used to hold the bead, it is less likely to cause bead to fly away or leak, thus not affecting the bead embroidery effect. Furthermore, when the guide rod body is shaken, the bead, after being positioned by the thickened section, is less likely to get stuck at the guide sleeve, allowing for a more stable fall.

[0022] Preferably, a smooth transition section is provided between the thickened section and the guide rod body to guide the beads and reduce friction between the beads and the guide rod, allowing the beads to fall more smoothly. The thickened section and the transition section can be integrally machined as a sleeve fitted over the guide rod. Alternatively, they can be separate components, fitted sequentially onto the outside of the guide rod as sleeves. Depending on the actual situation, sleeves of different diameters or sleeves of different thickened section heights can be replaced and installed on the outside of the guide rod to accommodate beads of different inner diameters, thus expanding the range of applications.

[0023] Alternatively, a separate guide post can be set at the lower end of the guide rod body. The diameter of the upper end of the cone of the guide post is smaller than the diameter of the guide rod body, so that the beads fall more smoothly and are less likely to get stuck at the connection.

[0032] The components include: guide rod body 1, connecting structure 2, connecting rod 201, connecting hole 202, thickened part 3, transition section 4, rod sleeve 5, bead 6, bead clamp 7, guide post 8, cylinder 801, and cone post 802. Detailed Implementation

[0033] The present invention will be further described below with reference to specific embodiments.

[0034] refer to Figure 1-9A bead guide rod for bead embroidery includes a guide rod body 1. The output end of the guide rod body 1 has a thickened portion 3, the diameter of which is larger than the diameter of the guide rod body. Typically, the diameter of the thickened portion matches the inner diameter of the beads transported by the guide rod body. A smaller diameter guide rod body 1 facilitates smooth sliding of the beads towards the output end. The upper end of the guide rod body 1 is used for independently threading beads or in conjunction with a bead threading device. After threading, it slides downwards to the output end for transport. The output end of the guide rod body 1 typically serves as the end point, cooperating with a bead feeding structure and suspended at the bead feeding clamp's bead-taking position, supplying beads to the reciprocating bead feeding clamp. The upper end of the guide rod body 1 may also have necessary shapes, such as grooves for clamping and positioning the guide rod; a spiral section and / or a curved section wound around at least one rotating wheel for fixing the guide rod. Preferably, the thickened portion 3 is concentrically arranged with the guide rod body 1.

[0035] In existing technologies, the guide rod is made of thin steel wire, which can accommodate beads of various aperture sizes. However, when the inner diameter of the bead is significantly larger than the diameter of the guide rod, the bead is prone to skew, causing it to tilt and fall during clamping, resulting in bead slippage and other issues. Therefore, a thickened section is added to the output end of the guide rod, positioned where the bead falls. The guide rod body 1 maintains a smaller diameter, making it easier to thread and guide the bead towards the output end. This also reduces the impact of threading the bead at the top and the movement of the positioning structure on the guide rod. When the bead falls from the guide rod body 1 to the output end, the thickened section closely fits the inner diameter of the bead, allowing for more precise bead positioning and preventing skew. This ensures the guide rod's controllability over the bead, maintaining the bead's verticality and making the bead drop more stable. Furthermore, it reduces the likelihood of bead slippage and slippage when clamped by the bead clamp 7, resulting in higher clamping efficiency and better bead embroidery quality. The high degree of fit mentioned here does not mean that the bead is completely and tightly fitted to the thickened part without any gaps. Rather, it means that there is still space between the guide rod and the bead for the bead to fall, but the space for the bead to tilt is very small.

[0036] Preferably, the height of the thickened portion 3 is greater than or equal to the height of the bead 6 conveyed by the guide rod body. The thickened portion 3 needs to have a high degree of fit with the bead, so its height must be at least the same as the height of the bead to more accurately position the bead, ensure that the bead fits the guide rod better, and prevent it from tilting or slipping to one side.

[0037] A transition section 4 for guiding and transitioning is provided between the thickened part 3 and the guide rod body 1. The outer surface of the transition section 4 is a smooth, conical transition surface. The smooth transition surface reduces surface friction and minimizes damage to the beads. The conical shape of the transition section, with its diameter gradually increasing from top to bottom, provides a guiding effect on the beads, allowing them to enter the thickened part 3 more smoothly.

[0038] The guide rod body 1 can be machined as a whole, or the thickened part 3 and the transition section 4 can be integrated as a single piece, such as... Figure 4 The guide rod body 1 is machined into a sleeve 5, which is then fitted onto the outside of the guide rod body 1. The guide rod body 1 is machined separately, while the thickened part 3 and the transition section 4 are machined together to form the sleeve 5, which is then fitted onto the outside of the guide rod body 1. The sleeve 5 can be replaced with different diameter sleeves according to the inner diameter of the actual beads being transported, thus accommodating beads with different apertures and expanding its applicability. The material of the sleeve 5 is not limited and can be rubber, plastic, metal, etc.

[0039] The thickened section 3 and the transition section 4 can also be set separately and finally installed on the outside of the guide rod body 1. Multiple thickened sections 3 of different heights can be set to accommodate beads of different heights.

[0040] This utility model also discloses a bead guide rod for bead embroidery, including a bead guide rod body 1. The output end of the bead guide rod body 1 is provided with a guide post 8. The guide post 8 includes a cylinder 801 at the lower end and a conical post 802 at the upper end. The diameter of the cylinder 801 is larger than the diameter of the bead guide rod body 1. The upper end of the conical post 802 is a small-diameter end. The diameter of the small-diameter end where it connects with the bead guide rod body 1 is less than or equal to the diameter of the bead guide rod body 1. The end face of the small-diameter end of the conical post does not extend beyond the end face of the bead guide rod body at the point where it connects with the bead guide rod body.

[0041] Preferably, the diameter of the contact surface 9 is smaller than the diameter of the guide rod body 1 to prevent the formation of a step between the cone 802 and the guide rod body 1, which would prevent the bead from falling smoothly and prevent the bead from getting stuck at the step.

[0042] The guide post 8 is welded, bonded, or press-fitted to the guide ball rod body 1, or a connecting structure 2 is provided between the guide post 8 and the guide ball rod body 1. The connecting structure 2 is used to connect the guide post 8 and the guide ball rod body 1, and also allows the guide post 8 to be detached for easy installation and replacement.

[0043] The connecting structure 2 includes a connecting rod 201 located at the lower end of the guide bead rod body 1 and a connecting hole 202 located on the guide post 8 that mates with the connecting rod 201, for example... Figure 5 , 8 Alternatively, a connecting hole 202 can be located at the lower end of the guide rod body 1, and a connecting rod 201 (not shown) can be located at the upper end of the guide post 8 and mate with the connecting hole 202. The connecting structure 2 can also adopt an existing structure. The connecting hole 202 can be a through hole, such as a connecting hole on the guide post 8. Figure 5Alternatively, holes can be partially opened on the guide rod body or guide post, as long as they meet the requirements for connection with the connecting rod 201. Preferably, the guide rod body 1 and the guide post 8 are concentrically arranged, that is, the guide rod body 1 and the cylindrical 801 or the conical 802 of the guide post 8 are concentrically arranged. Preferably, the cylindrical 801 and the conical 802 are concentrically arranged.

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 within the patent protection scope of the present utility model.
