Description

Technical Field

[0001] This application relates to the technical field of jewelry production and processing, and in particular to a flat-bottomed diamond bead feeding mechanism. Background Technology

[0002] Common flat-bottomed rhinestones include a bottom surface, a table surface, and multiple inclined surfaces between the bottom surface and the table surface. The bottom surface is circular, the table surface is a regular polygon, and the bottom surface and the table surface have a common central axis. A flat-bottomed rhinestone with a central hole has a circular hole at the axis position of the flat-bottomed rhinestone. Irregularly shaped beads are pearl jewelry with inconsistent shapes, sizes, and specifications.

[0003] Both flat-bottomed rhinestones with central holes and irregularly shaped beads are decorative ornaments, widely used as accessories for clothing, shoes, and handicrafts. When sewing these ornaments with central holes, manual threading is usually required. The manual threading process is labor-intensive, resulting in low work efficiency. Furthermore, as the manual work time increases, it can easily cause visual fatigue. Utility Model Content

[0004] In order to improve the threading efficiency of flat-bottom drills or irregularly shaped beads, this application provides a feeding mechanism for flat-bottom drills and irregularly shaped beads.

[0005] This application provides a flat-bottomed drill ball feeding mechanism, which adopts the following technical solution:

[0006] A flat-bottomed rhinestone bead feeding mechanism includes a vertically arranged fixed base, a wire clamping assembly disposed on the fixed base for mounting a threading wire, and a feeding device disposed above the fixed base. The feeding device includes a material cup for holding decorative rhinestones and a feeding assembly for threading the rhinestones in the material cup onto the wire. The feeding assembly is installed between the material cup and the fixed base.

[0007] By adopting the above technical solution, during the threading process of jewelry rhinestones, all the jewelry rhinestones to be threaded can be placed into the material cup, and the jewelry rhinestones in the material cup can fall onto the feeding component. The feeding component then allows the jewelry rhinestones to fall onto the steel wire clamped by the wire clamping component. This allows the threading of jewelry rhinestones to be controlled by a mechanical structure, avoiding manual threading and improving threading efficiency.

[0008] Preferably, the feeding assembly includes a feeding tray base mounted on the upper end of the fixed base, a rotating platform rotatably mounted on the feeding tray base, and a feeding tray cover fastened to the feeding tray base. A cavity is formed between the feeding tray cover and the feeding tray base to accommodate the rotating platform, and the cavity can communicate with the inside of the material cup. The feeding tray cover and the feeding tray base are provided with a discharge port at the same position near the outer side, and the discharge port is aligned with the upper end of the steel wire.

[0009] By adopting the above technical solution, the jewelry rhinestones to be threaded can fall onto the rotating platform through the material cup. Under the rotation of the rotating platform, the jewelry rhinestones gradually move to the outlet and fall from the outlet, thus allowing the fallen jewelry rhinestones to fall onto the steel wire.

[0010] Preferably, the base of the feeding tray is provided with a control component for controlling the rotation of the rotating platform. The control component includes a control motor fixed on a fixed base, and the control motor controls the rotation of the rotating platform.

[0011] By adopting the above technical solution and using electric control, the control motor can continuously control the rotation of the rotating platform, thereby enabling the feeding device to continuously feed materials and improving the feeding efficiency.

[0012] Preferably, a soft rubber ring is fixed at the center of the inner surface of the upper surface of the feeding tray cover. The soft rubber ring can move closer to the rotating platform, and the inside of the soft rubber ring can communicate with the inside of the material cup.

[0013] By adopting the above technical solution, the rhinestones in the material cup can first fall into the soft rubber ring, and then, through the rotation of the rotating platform, the rhinestones in the soft rubber ring rotate out from the inside, which plays a role in controlling the falling speed of the rhinestones and avoiding the accumulation of rhinestones in a large number of them falling into the rotating platform without any limit, thus preventing the rhinestones from being piled up and making it impossible to thread them effectively.

[0014] Preferably, a spiral feeding ring groove is formed on the inner surface of the feeding tray cover, and the outer end of the feeding ring groove is connected to the discharge port.

[0015] By adopting the above technical solution, the rotating platform can control the jewelry drills to move sequentially to the outlet along the direction of the feeding ring groove, avoiding the accumulation of jewelry drills on the rotating platform, thereby improving the threading efficiency of jewelry drills.

[0016] Preferably, an annular quantitative storage groove is provided on the inner surface of the upper surface of the feeding tray and at the position of the soft rubber ring, which can accommodate the jewelry rhinestones coming out of the soft rubber ring. Multiple inlets are provided between the quantitative storage groove and the feeding ring groove for the jewelry rhinestones to move into the feeding ring groove.

[0017] By adopting the above technical solution, the jewelry rhinestones rotating out of the soft rubber ring can be temporarily stored in the quantitative storage tank, allowing the jewelry rhinestones to be moved into the feeding ring channel in batches and in quantitative quantities, avoiding congestion at the feed inlet.

[0018] Preferably, the size of the feed inlet is the same as the size of the jewelry rhinestone, and slopes that match the inclined surface of the jewelry rhinestone are provided on both sides of the feed inlet.

[0019] By adopting the above technical solution, the set ramp allows the jewelry rhinestones to move out in a fixed direction. Therefore, the set ramp allows the jewelry rhinestones to be moved out of the quantitative storage tank with their faces facing up, so that all the jewelry rhinestones on the wire are kept facing up, which is convenient for subsequent direct use and avoids individual adjustment.

[0020] Preferably, a columnar magnet block is mounted on the upper surface of the rotating platform, and the magnet block is rotatably engaged in a quantitative storage tank.

[0021] By adopting the above technical solution, the magnet can rotate around the soft rubber ring, and the magnet rotates in the quantitative storage tank. During the rotation of the magnet, it can agitate the jewelry rhinestones in the quantitative storage tank, thereby driving the jewelry rhinestones to flip over and allowing the flipped jewelry rhinestones to quickly move through the feed port into the feeding ring channel, thus improving the efficiency of threading the jewelry rhinestones.

[0022] Preferably, a material guiding component is provided at the discharge port. The material guiding component includes an upper material guiding block connected to the upper cover of the feeding tray and a lower material guiding block connected to the base of the feeding tray. The upper material guiding block has a connected feeding channel, and the lower material guiding block has a discharge port located at the upper end of the steel wire. The feeding channel is connected to the discharge port.

[0023] By adopting the above technical solution, the jewelry drill that moves from the rotating platform to the outlet can be repositioned by the action of the upper and lower guide blocks, so that the jewelry drill can fall accurately from the outlet and the round hole of the jewelry drill can be aligned with the steel wire.

[0024] Preferably, the surface of the rotating platform is fixed with multiple pusher protrusions arranged in the radial direction, and the multiple pusher protrusions are evenly arranged circumferentially along the axial direction of the rotating platform.

[0025] By adopting the above technical solution, the set pusher protrusion can increase the surface roughness of the rotating platform and prevent the jewelry drill from slipping inside the feeding ring groove and being unable to move effectively.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. During the threading process of the jewelry rhinestones, the jewelry rhinestones can be put into the material cup and allowed to fall naturally into the rotating platform. The rotating platform can drive the falling jewelry rhinestones to rotate along the direction of the feeding ring groove, and then let the jewelry rhinestones fall into the steel wire from the position of the guide component.

[0028] 2. The rhinestones falling from the material cup can first fall into the quantitative storage tank. Then, under the action of the magnet, the rhinestones in the quantitative storage tank are stirred to turn the rhinestones to the right side. Then, the turned rhinestones are correctly moved into the material guide component. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses a flat-bottomed drill ball feeding mechanism.

[0040] Reference Figure 1 A flat-bottomed rhinestone bead feeding mechanism includes a vertically arranged fixed base 1 and a wire clamping assembly 2 arranged on the fixed base 1. The wire clamping assembly 2 is used in conjunction with a pair of clamping claws 21 that mesh with gears. The pair of clamping claws 21 are used to clamp the wire 22 for threading. A feeding device 3 for threading the rhinestone onto the wire 22 is arranged above the fixed base 1. The feeding device 3 includes a material cup 31 arranged above the fixed base 1. The material cup 31 has a cylindrical structure and is used to hold the rhinestone to be threaded. During operation, the rhinestone can be automatically threaded onto the wire 22 through the feeding device 3.

[0041] Reference Figure 1 , Figure 2 and Figure 3The feeding device 3 includes a feeding assembly 32 disposed between the upper end of the fixed base 1 and the material cup 31. The feeding assembly 32 includes a feeding tray base 321 mounted on the upper end of the fixed base 1 and having a disc-shaped structure, a rotating platform 322 rotatably disposed on the feeding tray base 321 and having a disc-shaped structure, and a feeding tray cover 323 fastened to the feeding tray base 321. The cross-section of the feeding tray base 321 has a U-shaped structure, thereby forming a cavity between the feeding tray base 321 and the feeding tray cover 323 that can accommodate the rotating platform 322. The rotating platform 322 is rotatably disposed on the feeding tray base 321 and positioned between the upper end of the fixed base 1 and the material cup 31. Inside the cavity, the material cup 31 is fixed on the upper cover 323 of the feeding plate. A feeding port is provided at the bottom of the material cup 31, which connects the material cup 31 with the cavity, allowing the jewelry rhinestone in the material cup 31 to fall onto the rotating platform 322. Near the edge of the upper cover 323 of the feeding plate and the base 321 of the feeding plate, there is a discharge port 324 for the jewelry rhinestone to rotate out. The upper end of the steel wire 22 through which the jewelry rhinestone is inserted is aligned with the discharge port 324. When the jewelry rhinestone rotates out from the discharge port 324, the round hole on the jewelry rhinestone is aligned with the steel wire 22, so that the steel wire 22 is inserted into the jewelry rhinestone.

[0042] A control component 33 for controlling the rotation of the rotating platform 322 is provided between the loading tray base 321 and the fixed seat 1. The control component 33 includes a control motor fixed on the fixed seat 1. The control motor is used to control the clamping claws 21 to clamp or release the steel wire 22. A drive gear is fixed on the output shaft of the control motor. The drive gear is installed on one of the clamping claws 21. The clamping claws 21 are clamped or released by the gear meshing. A driven gear 331 is fixed at the center of the lower surface of the rotating platform 322. The drive gear meshes with the driven gear 331, thereby controlling the rotation of the rotating platform 322 on the loading tray base 321.

[0043] The feeding assembly 32 also includes a soft rubber ring 34 fixed to the inner surface of the feeding tray cover 323. The upper end of the soft rubber ring 34 is fixed at the center of the feeding tray cover 323. An opening is provided at the center of the feeding tray cover 323. The opening is connected to the discharge port of the material cup 31 and the inside of the soft rubber ring 34 respectively. The lower end of the soft rubber ring 34 can approach the rotating platform 322 and leave a gap between it and the rotating platform 322, so that the jewelry rhinestones inside the material cup 31 can fall into the rotating platform 322 inside the soft rubber ring 34. When the rotating platform 322 is rotating, the jewelry rhinestones inside the soft rubber ring 34 can move to the rotating platform 322 outside the soft rubber ring 34 through the gap, and then rotate the jewelry rhinestones to the discharge port 324, so that the jewelry rhinestones fall onto the steel wire 22.

[0044] Reference Figure 1 , Figure 2 and Figure 3A spiral feeding ring groove 35 is formed on the inner surface of the feeding tray cover 323. The outer end of the feeding ring groove 35 can connect to the outlet 324, so that the jewelry rhinestones moving out of the soft rubber ring 34 can move sequentially to the outlet 324 along the feeding ring groove 35, avoiding the accumulation of jewelry rhinestones on the rotating platform 322, thereby improving the threading efficiency of jewelry rhinestones. A quantitative storage groove 36 is formed on the inner surface of the feeding tray cover 323. The quantitative storage groove 36 is located in the soft rubber ring 34. At the location of the rubber ring 34, the jewelry drills that move out from inside the soft rubber ring 34 can be stored in the quantitative storage tank 36. The quantitative storage tank 36 is located in the middle of the feeding ring channel 35, and multiple feed ports 37 are opened between the quantitative storage tank 36 and the feeding ring channel 35. The jewelry drills in the quantitative storage tank 36 can move into the feeding ring channel 35 through the feed ports 37, and then, under the rotation of the rotating platform 322, the jewelry drills in the feeding ring channel 35 gradually move to the discharge port 324. Furthermore, the size of the feed port 37 matches the size of the jewelry drill, and ramps 371 matching the inclined surface of the food drill are provided on both sides of the feed port 37. The ramps 371 allow the jewelry drills to move out in a fixed direction. Therefore, the ramps 371 allow the jewelry drills to move out of the quantitative storage tank 36 with their faces facing upwards, so that all the jewelry drills on the wire 22 keep their faces upwards, which is convenient for direct use later and avoids individual adjustment.

[0045] A columnar magnet block 38 is fixed on the rotating platform 322 and located outside the soft rubber ring 34. The magnet block 38 can rotate around the soft rubber ring 34 and rotates in the quantitative storage tank 36. During the rotation of the magnet block 38, it can agitate the jewelry diamonds in the quantitative storage tank 36, thereby driving the jewelry diamonds to flip over and allowing the flipped jewelry diamonds to quickly move through the feed port 37 to the feeding ring groove 35, thus improving the efficiency of threading the jewelry diamonds.

[0046] Reference Figure 1 , Figure 4 and Figure 5A guide component 4 is provided at the outlet 324 to allow the jewelry drill to fall accurately onto the steel wire 22. It includes an upper guide block 41 connected to the upper cover 323 of the feeding tray and a lower guide block 42 connected to the base 321 of the feeding tray. The lower guide block 42 has a drop port 421 that cooperates with the jewelry drill at its end. An feeding channel 411 is provided inside the upper guide block 41. The feeding channel 411 is connected to the drop port 421 and to the feeding ring groove 35. This allows the jewelry drill inside the feeding ring groove 35 to move into the upper guide block 41. With the push of the subsequent jewelry drill, the jewelry drill moves to the drop port 421, so that the round hole on the jewelry drill is aligned with the steel wire 22 and the steel wire 22 is threaded onto the jewelry drill. The guide component 4 improves the accuracy of threading the jewelry drill and prevents the jewelry drill from falling outside the steel wire 22. A pair of support plates 5 are symmetrically arranged on the lower guide block 42 at the material drop port 421. The two support plates 5 are flipped and set on the lower guide block 42. The support plates 5 are horizontal in the initial state and can only be flipped downward in one direction. When the jewelry drill moves to the material drop port 421, it can first move to the two support plates 5. Then the support plates 5 automatically open, allowing the jewelry drill to fall vertically downward into the steel wire 22, improving the accuracy of falling into the steel wire 22 and preventing the jewelry drill from falling at an angle from the material drop port 421, which would prevent the steel wire 22 from being aligned with the round hole of the jewelry drill.

[0047] Multiple pusher protrusions 6 are fixed on the surface of the rotating platform 322. The pusher protrusions 6 are arranged along the radial direction of the rotating platform 322, and the multiple pusher protrusions 6 are evenly distributed circumferentially along the axial direction of the rotating platform 322. The pusher protrusions 6 can increase the surface roughness of the rotating platform 322 and prevent the jewelry drill from slipping inside the feeding ring groove 35 and being unable to move effectively.

[0048] The implementation principle of the flat-bottomed rhinestone bead feeding mechanism in this application embodiment is as follows: When threading the rhinestone, the rhinestone to be threaded is poured into the material cup 31. The rhinestone can first fall into the soft rubber ring 34. The rotating platform 322 moves the rhinestone in the soft rubber ring 34 to the quantitative storage tank 36. The rotating magnet block 38 can stir the rhinestone, allowing the rhinestone to gradually turn to the front. Then it moves to the feeding ring channel 35, and gradually moves between the upper guide block 41 and the lower guide block 42, and finally falls from the drop port 421 onto the steel wire 22.

[0049] Those skilled in the art should understand that the embodiments of the present invention described above are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the described principles, the implementation of the present invention may have any modifications or variations.
