[0002] With the development of the jewelry industry, there are more and more accessories such as necklaces, sweater chains, and bracelets. These jewelry items all need to string the accessories together through wires, and the wire lengths required for each style are different. Traditional winding equipment cannot adjust the length of the winding coil. If the wire for a sweater chain is used as the wire for a necklace, it will inevitably cause waste of wire. When different lengths of wire are needed, the winding equipment has to be replaced, which is too troublesome and not very practical. Based on this problem, we have designed a winding equipment that can adjust the length of wire for jewelry. Summary of the Invention

One end of an adjusting rod is pin-connected to each adjusting rod mounting seat, and the other end of the adjusting rod is pin-connected to a telescopic rod mounting seat. A telescopic rod is provided on the telescopic rod mounting seat. Four support rod mounting seats are evenly installed on the fixed ring. One end of a support rod is pin-connected to each support rod mounting seat, and the other end of the support rod is pin-connected to a sliding block. The sliding block can slide along a guiding groove provided on the adjusting rod. The telescopic rod includes an outer hollow cylindrical rod and an inner hollow cylindrical rod. The outer hollow cylindrical rod is slidably connected to the outer surface of the inner hollow cylindrical rod.

A second limiting block is provided at the end of the inner hollow cylindrical rod facing outward, and the second limiting block is located in a through groove provided on the moving disk.

[0005] As a preferred structure, a wire pulling device is further provided on the fixed plate. Both the wire pulling device and the wire winding device are located on the same side of the fixed plate. The wire pulling device is vertically arranged with respect to the fixed plate. The wire pulling device includes a cylindrical support frame and an arc-shaped wire hole frame that cooperates with it.

[0006] As a preferred structure, the arc-shaped wire hole frame includes an arc surface provided with a plurality of wire passing holes, and torsion springs are provided on both sides of the arc surface. The ends of the torsion springs are inserted into the concave holes on the corresponding cylindrical support frame, and the arc surface on the arc-shaped wire hole frame is attached to the outer wall of the cylindrical support frame by the torsion springs.

[0007] As a preferred structure, cotton layers are provided at the portions where the inner wall of the arc surface of the arc-shaped wire hole frame contacts the outer wall of the cylindrical support frame.

[0008] As a preferred structure, a wire head fixing device is provided on one of the four telescopic rods. The wire head fixing device includes a plurality of through holes, and the plurality of through holes are arranged in a row and evenly distributed on the outer hollow cylindrical rod and the inner hollow cylindrical rod. And a convex tooth is provided in each through hole, and the tip direction of the convex tooth is the same as the rotation direction of the rotating shaft.

[0009] As a preferred structure, the thickness of the convex tooth is less than the wall thickness of the outer hollow cylindrical rod and the inner hollow cylindrical rod, and the convex tooth is close to the outer surfaces of the outer hollow cylindrical rod and the inner hollow cylindrical rod.

[0014] The movable disk in the winding device can move left and right on the threaded rod. The relative distance between the movable disk and the fixed disk is adjusted by a nut with a limiting function. The nut can prevent the movable disk from moving to the right. Since there is a spring wound around the threaded rod between the fixed ring on the movable disk and the base on the fixed disk, the two ends of the spring always abut against the fixed ring and the base respectively and are in a compressed state. The deformed spring has a force to the right. With the cooperation of the spring and the nut, it can ensure that the movable disk does not displace left and right during operation, having good stability. When adjusting the length of the coil through the nut, the adjusting rod and the supporting rod cooperate with each other, so that both ends of the telescopic rod slide along the chute of the fixed disk and the chute of the movable disk respectively, thereby realizing the function of adjustable length of the wire for jewelry.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] As Figures 1 to 4 shown, a wire winding device for adjusting the length of jewelry wire includes a fixing plate 2. A bearing 3 is embedded in the fixing plate 2. A rotating shaft 4 passes through the bearing 3. A driving device is installed at one end of the rotating shaft 4, and a wire winding device is installed at the other end of the rotating shaft 4. A wire pulling device 22 is also provided on the fixing plate 2. The wire pulling device 22 and the wire winding device are both located on one side of the fixing plate 2, and the wire pulling device 22 is vertically arranged with respect to the fixing plate 2. The driving device is used to drive the operation of the wire winding device. The wire winding device, in cooperation with the wire pulling device 22, enables the wire to have tension during winding, and there will be no phenomenon of messy coils.

[0024] The wire winding device includes a fixed disc 8 installed at the end of the rotating shaft 4, and the end of the rotating shaft 4 is fixed at the center of one side of the fixed disc 8. A base 10 is provided at the center of the other side of the fixed disc 8. A threaded rod 20 collinear with the rotating shaft 4 is fixed on the base 10. A moving disc 9 with a circular hole is provided on the threaded rod 20, and the circular hole is located at the center of the moving disc 9. A nut 21 with a limiting function is provided on the extended section of the threaded rod 20 passing through the circular hole. A fixed ring 11 is provided on the inner surface of the moving disc 9 along the outer circumference of the circular hole. A spring 32 wound around the threaded rod 20 is provided between the fixed ring 11 and the base 10. Both ends of the spring 32 always abut against the fixed ring 11 and the base 10 respectively and are in a compressed state. By adjusting the position of the nut 21 on the threaded rod 20, the relative distance between the moving disc 9 and the fixed disc 8 is changed. Since a spring 19 wound around the threaded rod 20 is provided between the fixed ring 11 and the base 10, the elastic deformation of the compressed spring 19 will push the moving disc 9 outwards. With the structure of the nut 21 itself, the moving disc 9 can have better stability.

[0025] Four adjusting rod mounting seats 13 are evenly installed on the base 10. One end of an adjusting rod 15 is pin-connected to each adjusting rod mounting seat 13. The other end of the adjusting rod 15 is pin-connected to a telescopic rod mounting seat 12. A telescopic rod is provided on the telescopic rod mounting seat 12. Four support rod mounting seats 14 are evenly installed on the fixed ring 11. One end of a support rod 16 is pin-connected to each support rod mounting seat 14. The other end of the support rod 16 is pin-connected to a sliding block 17. The sliding block 17 can slide along a guiding groove provided on the adjusting rod 15. When the relative distance between the fixed disc 8 and the moving disc 9 changes, the telescopic rods in four directions will generate radial movement on the fixed disc 8 and the moving disc 9, thereby realizing the adjustment of the coil length.

[0026] The telescopic rod includes an outer hollow cylindrical rod 18 and an inner hollow cylindrical rod 26. The outer hollow cylindrical rod 18 is slidably connected to the outer surface of the inner hollow cylindrical rod 26. A first limit block 51 is provided at one end of the outer hollow cylindrical rod 18 facing the extending direction, and the first limit block 51 is located in a chute provided on the fixed disk 8. A second limit block 52 is provided at one end of the inner hollow cylindrical rod 26 facing the extending direction, and the second limit block 52 is located in a through groove provided on the moving disk 9. Because when the relative distance between the fixed disk 8 and the moving disk 9 changes, through the sliding fit of the outer hollow cylindrical rod 18 and the inner hollow cylindrical rod 26, it can be extended or shortened. The first limit block 51 on the outer hollow cylindrical rod 18 is located in the chute of the fixed disk 8, and the second limit block 52 on the inner hollow cylindrical rod 26 is located in the through groove of the moving disk 9. The purpose is to ensure that the telescopic rod is always parallel during the radial movement process and ensure the stability of winding.

[0027] The driving device includes a motor 1 installed on the fixed plate 2. A transmission wheel 7 is provided on the motor 1. The transmission wheel 7 drives a driven wheel 5 at one end of the rotating shaft 4 through a transmission belt, and the diameter of the transmission wheel 7 is smaller than that of the driven wheel 5. The driven wheel 5 is located at the end of the rotating shaft 4. Usually, the rotation speed of the motor 1 is relatively fast. Therefore, the diameter of the transmission wheel 7 is smaller than that of the driven wheel 5 to ensure that the rotating shaft 4 has a slower rotation speed. A redirecting roller 6 acting on the outer surface of the transmission belt is also provided on the transmission belt. The redirecting roller 6 is fixed to the fixed plate 2 through a fixed shaft. The redirecting roller 6 can press the transmission belt to increase its wrap angle with the transmission wheel 7 and increase the stability of winding.

[0028] The wire pulling device 22 includes a cylindrical support frame 25 and an arc-shaped wire hole frame 23. Torsion springs 24 are provided on both sides of the arc-shaped wire hole frame 23, and the ends of the torsion springs 24 are installed on the cylindrical support frame 25. The arc-shaped wire hole frame 23 adheres its arc surface to the arc surface of the cylindrical support frame 25 through the torsion springs 24. Open the arc-shaped wire hole frame 23 and pass the wire head through each wire hole of the arc-shaped wire hole frame 23. After passing through, according to the self-performance of the torsion spring, press the wire on the cylindrical support frame 25, so that the wire between the wire pulling device 22 and the winding device has tension, ensuring that the wire will not be disordered during the winding process. And cotton layers are provided at the contact parts between the inner wall of the arc surface of the arc-shaped wire hole frame 23 and the outer wall of the arc surface of the cylindrical support frame 25, and the cotton layers better protect the wire from being worn.

[0029] Among the four telescopic rods, one telescopic rod is provided with a wire head fixing device. The wire head fixing device includes a number of through holes. The number of through holes are arranged in a row and evenly distributed on the outer hollow cylindrical rod 18 and the inner hollow cylindrical rod 26. And a convex tooth 27 is provided in each through hole. The tip direction of the convex tooth 27 is the same as the rotation direction of the rotating shaft 4. And the thickness of the convex tooth 27 is less than the wall thickness of the outer hollow cylindrical rod 18 and the inner hollow cylindrical rod 26. And the convex tooth 27 is close to the outer surfaces of the outer hollow cylindrical rod 18 and the inner hollow cylindrical rod 26. The purpose of this structure setting is that the wire head can be knotted on the convex tooth 27. The wire head is knotted in a way of winding around the convex tooth 27 once. When the wire winds around the convex tooth 27, there will be no problem that the wire cannot be wound because the outer wall of the inner hollow cylindrical rod 26 contacts the inner wall of the outer hollow cylindrical rod 18.

[0030] A scale mark 61 is provided on the outer surface of the moving disc 9. The scale mark 61 corresponds to beside one of the through grooves. The value of each scale corresponds to the length of one turn of the wire winding. And a scale mark 62 pointing to the scale mark 61 is provided on the back surface of the second limiting block 52. So that the naked eye can observe the position where the scale mark 62 on the second limiting block 52 corresponds to the scale mark 61. The scale of the scale mark 61 is set according to the length from the center of the moving disc 9 to the scale mark 62 being X, the length of one turn of the wire winding being Y. After the wire winds around the four telescopic rods, the coil is square. Ignoring the arc error at the four corners, Y = 4 X, and the position of the scale mark 62 corresponds to the starting position of the wire winding.

[0031] The working process of the present invention: First, observe the scale mark 2 on the moving disc 9. By adjusting the nut 21, when the relative distance between the moving disc 9 and the fixed disc 8 decreases, the included angle between the adjusting rod 15 and the base 10 increases, and the telescopic rod is lifted. At this time, the length of the coil will become larger. At the same time, the inner hollow cylindrical rod 26 and the outer hollow cylindrical rod 18 move towards each other, and vice versa. When the scale mark 2 is corresponded to the required scale mark 61 by adjusting the nut 21, after the wire passes through the wire pulling device 22, the wire head is knotted on the convex tooth 27 inside the telescopic rod. Turning on the motor 1 can realize the wire winding work for jewelry.

[0032] Such as Figures 5 to 6A wire winding device capable of adjusting the length of jewelry wire is shown. Its driving device adopts a manual driving mode. A steering wheel 28 is installed at the end of the rotating shaft 4, and an integral ratchet wheel 29 is provided on the rotating shaft 4. The ratchet wheel 29 cooperates with a pawl device 30 installed on a fixing plate. The pawl device 30 includes a fixing seat. A rotating shaft 33 and a fixing shaft 31 are provided on the fixing seat. A pawl 34 is provided on the rotating shaft 33 and cooperates with the ratchet wheel 29. One end of a spring 32 is connected to the fixing shaft 31, and the other end of the spring 32 is connected to the middle part of the pawl 34. The rotation direction of the steering wheel 28 is the same as the tooth tip direction of the convex teeth 27. When the hand is released, the cooperation between the pawl 34 and the ratchet wheel 29 will have a limiting effect on the rotating shaft 4.
