Description

Technical Field

[0001] The invention relates to the technical field of jewelry processing, in particular to a bead chain sewing machine and a bead chain processing method. Background Art

[0002] From ancient times to now, people have created various styles, characteristics and patterns of jewelry chains to beautify the human body. As people's living standards continue to improve, in order to meet personalized needs, the requirements for jewelry chain shapes are getting higher and higher.

[0003] Bead chain is a kind of jewelry chain, which is composed of multiple beads connected to each other. The earliest beads in the bead chain had a smooth surface and simple shape; but with the continuous improvement of living standards, people's demand for personalization is getting higher and higher, and gradually developed into designing various styles on the surface of the beads to meet the requirements of beautification. In the process of shaping the beads, a pattern cutting machine is used to form patterns to achieve a better aesthetic effect. However, the traditional pattern cutting machine has gradually exposed some unavoidable defects in long-term practical applications:

[0004] First, the processing method is relatively cumbersome, requiring individual beads to be processed one by one, and then these independently processed beads are strung together to form a complete jewelry chain. This process is not only lengthy and complicated, but also greatly limits production efficiency, making it difficult to meet the urgent demand for efficient production in the current market.

[0005] Secondly, traditional lathe machines have obvious shortcomings in terms of modeling accuracy. On the one hand, due to the poor clamping stability of the chain beads, it is difficult to ensure accurate positioning and stable operation when processing patterns on the surface of the chain beads, which greatly reduces the processing accuracy of the patterns and cannot provide stable and reliable lathe quality assurance for the products; on the other hand, it is difficult to accurately control the processing force of the lathe tool on the chain beads, which makes the lathe force on each chain bead uneven, resulting in subtle but significant differences in the lathe shape of the chain beads, which seriously affects the overall aesthetic coordination and refinement of the jewelry chain and weakens the competitiveness of the product in the market. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is: to provide a bead chain sewing machine and a bead chain processing method, which can continuously sewing and forming the beads of the bead chain, improve the forming efficiency, and reduce labor costs; at the same time, ensure the uniformity of the sewing force and improve the processing accuracy.

The Y-axis translation mechanism 53 is used to drive the Y-axis rotating mechanism 52 and the flower turning mechanism 51 to move closer to or away from the chain beads.

[0081] When it is necessary to carve beads, firstly manually pass the bead chain through the two chain clamping devices 2 so that one of the beads is located between the two chain clamping devices 2; the two chain clamping devices 2 rotate in the same direction around the X-axis, driving the bead chain to rotate as a whole; the upstream chain clamping device 2 moves upstream by the position of one bead, and then clamps the chain shaft upstream of the current bead; the downstream chain clamping device 2 opens the clamping end and is in a released state; the upstream chain clamping device 2 clamps the chain shaft and moves it downstream by the position of one bead, so that the upstream chain bead moves to the two chain clamping devices 2 between; the downstream chain clamp device 2 closes the clamping end to clamp the chain shaft on the downstream side of the current chain bead; the Z-axis rotating mechanism 4 drives the two sewing devices 5 to rotate around the Z-axis to adjust their feeding direction; the Y-axis rotating mechanism 52 adjusts the feeding angle of the sewing mechanism 51; the Y-axis translation mechanism 53 drives the sewing mechanism 51 to approach the chain bead to perform sewing on it; in this process, the feeding direction of the sewing device 5 and the feeding angle of the sewing mechanism 51 can be adjusted multiple times as needed; until a diamond pattern is formed on the surface of the chain bead.

[0082] In this process, firstly, the traditional method of molding only one bead at a time is changed, and the beads in the entire bead chain can be molded sequentially, and there is no need to thread the chain in the later stage, which improves the molding efficiency and reduces the labor cost. Secondly, through the cooperation of the two clamping chain devices 2, the clamping stability of the chain beads is improved, accurate positioning and stable operation are ensured, and the processing accuracy of the pattern is improved; at the same time, because the two car flower devices 5 are relatively set to carve the chain beads at the same time or at one time or sequentially, the uniformity of the car flower force is ensured each time, which improves the overall aesthetic coordination and refinement, and also improves the molding efficiency of the chain beads and shortens the molding process.

[0083] like Figures 1 to 7 As shown together, in the present application, the bead chain needs to be rotated to cooperate with the flower turning device 5 to form a pattern, wherein the rotation of the bead chain is completed by the clamping chain device 2. The clamping chain device 2 includes a clamping mechanism 21, an X-axis rotating mechanism 22, and an X-axis translation mechanism 23; the clamping mechanism 21 can rotate around the X-axis, and the inner hollow of the clamping mechanism 21 is provided with a material channel 216 for moving the bead chain, and the clamping mechanism 21 is used to clamp the chain shaft between two adjacent chain beads; the clamping mechanism 21 is drivingly connected to the X-axis rotating mechanism 22, and the X-axis rotating mechanism 22 is used to drive the clamping mechanism 21 to clamp the chain shaft between two adjacent chain beads and then drive the bead chain to rotate around the X-axis; the X-axis rotating mechanism 22 is installed at the action end of the X-axis translation mechanism 23, and the X-axis translation mechanism 23 is used to drive the X-axis rotating mechanism 22 and the clamping mechanism 21 to reciprocate along the X direction.

The clamping jaws 218 are rotatably installed between two adjacent mounting blocks 217.

An annular boss is provided on the outer wall of the clamping sleeve 214; along the X direction, the action end of the clamping cylinder 215 and the return spring 219 are respectively provided on both sides of the annular boss.

[0088] When the clamping cylinder 215 moves along the X direction toward the side close to the clamping seat 211, it drives the clamping sleeve 214 to move in the same direction and compresses the reset spring 219. At this time, the inner wall of the clamping sleeve 214 abuts against the clamping claw 218, so that the arc-shaped clamping surfaces 2181 of several clamping claws 218 move outward along the radial direction of the clamping guide tube 212 at the same time, thereby releasing the chain shaft; when the clamping cylinder 215 moves along the X direction toward the side away from the clamping seat 211, the reset spring 219 pushes the clamping sleeve 214 to move in the same direction so that the sleeve clamping inclined surface 2142 abuts against the clamping inclined surface 2183 of the clamping claw and continues to move, so that the arc-shaped clamping surfaces 2181 of several clamping claws 218 move inward along the radial direction of the clamping guide tube 212 at the same time, thereby clamping the chain shaft.
