Description

Technical Field

[0001] This invention relates to the field of jewelry processing equipment, and more particularly to an integrated Chopin machine. Background Technology

[0002] The Chopin machine is a device used for weaving chain jewelry. It can automatically weave metal wires into necklaces or bracelets with left-right spiral patterns. The finished products have exquisite patterns and have been popular with consumers in the market for many years, with a large demand.

[0003] A typical Chopin machine mainly consists of a camshaft, a feeding device, a cutter head, an upper clamp, and a lower clamp. The camshaft provides power to the processing device, the feeding device is used to spin the silk into threads and transport them, the cutter head is used to cut the threads into chain links, the upper clamp is used to weave the chain links and create patterns, and the lower clamp is used to close the gaps in the chain links. Through the continuous coordination between these devices, the production of woven chain jewelry can be completed.

[0004] During processing, the upper clamp drives the already woven chain, moving continuously between the feeding device and the lower clamp to fit new chain links onto the chain. The chain links are then patterned and welded, and this process is repeated to complete the chain weaving. As the chain length gradually increases, the chain mass also increases. When the chain moves with the upper clamp, the swaying amplitude of the entire chain body becomes more and more violent, making it difficult for other devices to secure the chain firmly. As a result, the chain can easily fall off the device, interrupting the entire processing. The processing personnel need to shut down the equipment and manually place the chain back onto the processing device before processing can continue. Therefore, additional time and labor costs are required to correct the process, resulting in lower processing efficiency. Summary of the Invention

[0005] In order to improve the processing efficiency of Chopin machines, this application provides an integrated Chopin machine.

[0006] The integrated Chopin machine provided in this application adopts the following technical solution: An integrated Chopin machine includes a camshaft, an upper clamp, and a base. The camshaft and the upper clamp are mounted on the base and are in contact with each other. A chain clamping assembly is also mounted on the base. The chain clamping assembly includes a clamping block, a clamping rod, and a drive rod. The clamping rod is mounted on the clamping block and is used to clamp a chain. One end of the drive rod is in contact with the camshaft, and the other end of the drive rod is fixedly connected to the clamping block. The drive rod is used to drive the clamping block to open and close.

[0007] By adopting the above technical solution, multiple cams are installed on the camshaft. The coaxial rotation of different cams drives the upper clamp and the chain clamp assembly to work, allowing the upper clamp and the chain clamp assembly to cooperate more seamlessly. During the chain link weaving process of the upper clamp, the clamping block is connected to the cam on the camshaft through the transmission rod. It can then continuously open and close under the contact of the far rest end of the cam, driving the clamping rod to clamp and fix the completed chain, preventing the chain from shaking significantly during movement, and thus preventing the chain from falling off the upper clamp. This allows the weaving work between the upper clamp and other devices to be carried out continuously and stably, eliminating the need for operators to monitor and correct the processing process, thereby improving the processing efficiency of the Chopin machine.

[0008] Optionally, the clamping block includes a moving block and a stationary block, and clamping rods are installed on both the moving block and the stationary block. The clamping rods are parallel to each other. The stationary block is fixedly installed on the machine base. The moving block is hinged to the side wall of the stationary block. The moving block and the transmission rod are fixedly connected.

[0009] By adopting the above technical solution, the moving block and the stationary block are connected by a hinge. Under the drive of the transmission rod, the moving block can rotate relative to the stationary block along the hinge axis to complete the opening and closing action of the clamping block, thereby driving the two clamping rods to move closer or further away from each other, so as to achieve the clamping and fixing of the chain.

[0010] Optionally, a return spring is provided on the clamping block, and the return spring is located at the hinge of the moving block and the stationary block.

[0011] By adopting the above technical solution, the return spring is used to help the clamp block quickly return to its closed position after opening, so as to improve the response speed of the clamping chain assembly and enable the clamping chain assembly to achieve precise and rapid cooperation with the upper clamping seat.

[0012] Optionally, a welding assembly is also installed on the base. The welding assembly includes a laser welding head, a mounting base, and a laser. The laser welding head is fixed on the mounting base, the mounting base is installed on the base, the laser is installed inside the base, and the laser welding head and the laser are connected.

[0013] By adopting the above technical solution, the welding assembly is used to weld and fix the opening of the chain link during the chain weaving process. The machine base is provided with a chamber for laser installation. The laser is directly integrated into the machine base during production, which makes the integration of the whole equipment higher and facilitates the subsequent handling and use of the entire chain weaving equipment, without the need to install the laser separately next to the machine base. The laser welding head is connected to the laser through an optical fiber and then mounted on the frame through a mounting base, which facilitates its use during the processing.

[0014] Optionally, the laser welding head includes a welding part and a connecting part, the connecting part is provided with an oil-blocking groove, and an optical fiber port is provided in the oil-blocking groove.

[0015] By adopting the above technical solution, the welding part is used to emit laser, the connecting part is used to connect optical fiber, the oil baffle groove on the connecting part is used to block lubricating oil stains, and the optical fiber port is set in the oil baffle groove to protect the signal transmission of the optical fiber from being negatively affected, thus ensuring the continuous stability of the welding process.

[0016] Optionally, the mounting base is provided with a mounting hole, the laser welding head is inserted into the mounting hole, and an adjusting bolt is threadedly connected to the mounting base. The screw of the adjusting bolt passes through the side wall of the mounting hole and abuts against the laser welding head.

[0017] By adopting the above technical solution, the adjusting bolt is used to adjust the welding point position of the laser welding head. When it is necessary to fine-tune the welding position of the laser welding head, rotating the adjusting bolt will cause the screw to abut against the outer wall of the laser welding head, causing the laser welding head to rotate slightly, thereby achieving precise adjustment of the welding position without having to move the mounting base significantly. This improves the accuracy and convenience of welding components.

[0018] Optionally, the upper clamp includes a housing, a chain clamp, and a transmission assembly. The chain clamp and the transmission assembly are installed inside the housing. The transmission assembly includes a rack and a gear shaft. The chain clamp is installed at one end of the gear shaft, and the rack and the gear shaft mesh with each other. A baffle is installed at the end of the rack. An abutment rod is rotatably connected to the base. One end of the abutment rod abuts against the baffle, and the other end of the abutment rod abuts against the camshaft.

[0019] By adopting the above technical solution, the chain clamp is used to clamp the chain and chain links, the transmission component is used to drive the chain clamp to rotate, and the abutment rod can abut against the baffle under the drive of the cam on the camshaft, thereby driving the rack to move. By abutting against the top and bottom surfaces of the baffle respectively, the abutment rod can drive the rack to move in different directions, thereby driving the rack to rotate both clockwise and counterclockwise. Finally, the chain clamp at the end of the rack drives the chain links to process different patterns, thus realizing the weaving and production of left and right spiral patterned chain links.

[0020] Optionally, a rotating rod is rotatably connected to the outer casing, one end of the rotating rod is engaged with the rack, and the other end of the rotating rod is fixedly connected to an adjustment plate.

[0021] By adopting the above technical solution, the adjustment plate is used to check the rotation angle and jaw status of the chain clamp. Before the equipment is put into operation, force is applied to the adjustment plate to drive the rotating rod to rotate. The rotating rod drives the rack through the snap-fit, which in turn drives the gear shaft and chain clamp to rotate. Then, it can be checked whether the rotation angle of the chain clamp is appropriate and whether the jaws are aligned. After the adjustment is correct, the equipment can be started for processing without checking while the equipment is in operation. This can reduce the defect rate and further improve the processing efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During the chain link weaving process in the upper clamp, the clamp block is connected to the cam on the camshaft through the transmission rod. It can then open and close continuously under the contact of the far rest end of the cam, driving the clamping rod to clamp and fix the completed chain, so as to prevent the chain from shaking significantly during movement and thus prevent the chain from falling off the upper clamp. This allows the weaving work between the upper clamp and other devices to be carried out continuously and stably, so that the processing personnel do not need to monitor and correct the processing process of the equipment, thereby improving the processing efficiency of the Chopin machine. 2. The machine base is equipped with a cavity for laser installation, which integrates the laser directly into the machine base during production, making the whole machine more integrated and facilitating the subsequent handling and use of the entire chain weaving equipment, without the need to install the laser separately next to the machine base; the laser welding head is connected to the laser via optical fiber and then mounted on the frame via a mounting bracket, making it easy to use during processing; 3. The adjusting bolt is used to adjust the welding point position of the laser welding head. When it is necessary to fine-tune the welding position of the laser welding head, rotating the adjusting bolt will cause the screw to abut against the outer wall of the laser welding head, causing the laser welding head to rotate slightly, thereby achieving precise adjustment of the welding position without having to move the mounting base significantly. This improves the accuracy and convenience of welding components. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses an integrated Chopin machine. (Refer to...) Figure 1 and Figure 2 The integrated Chopin machine includes a camshaft 1, a feeding device 31, a cutter holder 32, an upper clamp 2, a lower clamp 33, and a machine base 3. The machine base 3 is square. The camshaft 1, the feeding device 31, the cutter holder 32, the upper clamp 2, and the lower clamp 33 are all mounted on the machine base 3. The camshaft 1 is horizontally mounted, while the feeding device 31 and the cutter holder 32 are vertically mounted. The upper clamp 2 and the lower clamp 33 are also horizontally mounted. The feeding device 31 can form the metal wire into a spiral shape and feed it out. The cutter holder 32 can cut the spiral wire into open chain links. The upper clamp 2 can move the open chain links to the lower clamp 33. The lower clamp 33 can close and clamp the opening of the chain links. The upper clamp 2 then processes the chain links with patterns. Through the continuous coordination between the various devices, the production of woven chain jewelry can be completed.

[0033] Reference Figure 2 and Figure 5 The camshaft 1 is equipped with multiple cams, and the base 3 is rotatably connected with multiple abutment rods 34. Each abutment rod 34 corresponds to a cam. One end of the abutment rod 34 is in contact with the cam, and the other end of the abutment rod 34 is in contact with the feeding device 31, the cutter seat 32, the upper clamp seat 2, and the lower clamp seat 33 in sequence. The camshaft 1 can drive the feeding device 31, the cutter seat 32, the upper clamp seat 2, and the lower clamp seat 33 to work together through the abutment rods 34 to complete the weaving of the metal necklace.

[0034] Reference Figure 2 and Figure 3 The machine base 3 is also equipped with a chain clamping assembly 4, which is located between the upper clamping seat 2 and the lower clamping seat 33. The chain clamping assembly 4 includes a clamping block 41, a clamping rod 42, and a transmission rod 43. The clamping block 41 includes a moving block 411 and a stationary block 412. The stationary block 412 is fixedly installed on the machine base 3, and the moving block 411 is hinged to the side wall of the stationary block 412. Both the moving block 411 and the stationary block 412 are equipped with clamping rods 42, which are parallel to each other. The clamping rods 42 can clamp and fix the woven chain. One end of the transmission rod 43 is fixedly connected to the moving block 411, and the other end of the transmission rod 43 is in contact with the cam on the camshaft 1. The transmission rod 43 can... The cam's action causes the moving block 411 to rotate relative to the stationary block 412 along the hinge axis, completing the opening and closing action of the clamping block 41. This, in turn, causes the two clamping rods 42 to move closer or further apart, thus clamping and fixing the chain. This prevents the chain from swaying significantly during movement, thereby avoiding the chain from falling off the upper clamping seat 2. This allows the coordinated weaving work between the upper clamping seat 2 and other devices to proceed continuously and stably without the need for operators to monitor and correct the processing. The entire machine can independently complete the weaving of chain jewelry, thereby improving the automation level and processing efficiency of the Chopin machine.

[0035] Reference Figure 2 and Figure 3 A return spring 413 is fixedly installed on the hinge shaft of the moving block 411 and the stationary block 412. The return spring 413 is used to help the clamping block 41 quickly return to its closed position after opening, so as to improve the response speed of the clamping chain assembly 4 and enable the clamping chain assembly 4 to achieve more precise and faster cooperation with the upper clamping seat 2.

[0036] Reference Figure 4 and Figure 5The upper clamp 2 includes a housing 21, a chain clamp 22, and a transmission assembly 23. The chain clamp 22 and the transmission assembly 23 are installed inside the housing 21. The transmission assembly 23 includes a rack 231 and a gear shaft 232. The rack 231 is installed vertically, and the gear shaft 232 is installed horizontally. The rack 231 and the gear shaft 232 mesh with each other. The chain clamp 22 is installed at one end of the gear shaft 232. The chain clamp 22 can clamp the chain and chain links. The transmission assembly 23 can drive the chain clamp 22 to rotate. A baffle 24 is fixedly installed at the end of the rack 231. The baffle 24 is elliptical in shape. Two abutting rods 34 are respectively connected to the two ends of the baffle 24. One abutting rod 34 is located above the baffle 24 and the other abutting rod 34 is located below the baffle 24. The two abutting rods 34 can abut the top and bottom surfaces of the baffle 24 respectively under the drive of the camshaft 1. The baffle 24 drives the rack 231 to move in the vertical direction, which in turn drives the gear shaft 232 to rotate clockwise or counterclockwise. Finally, the chain clamp 22 at the end of the gear shaft 232 drives the chain link to process different patterns, thereby realizing the weaving and production of left and right spiral patterned chain links.

[0037] Reference Figure 4 and Figure 5 A rotating rod 25 is rotatably connected inside the outer casing 21. One end of the rotating rod 25 has a slot, through which it can engage with the rack 231. A through hole is provided on the side wall of the outer casing 21, through which the other end of the rotating rod 25 passes. An adjustment plate 26 is fixedly connected to the other end of the rotating rod 25. The adjustment plate 26 is used to check the rotation angle and jaw state of the chain clamp 22. Before the equipment is put into operation, force is applied to the adjustment plate 26 to drive the rotating rod 25 to rotate. The rotating rod 25 drives the rack 231 to move through the engagement, which in turn drives the gear shaft 232 and the chain clamp 22 to rotate. Then, it can be checked whether the rotation angle of the chain clamp 22 is appropriate and whether the jaws are aligned. After the adjustment is correct, the equipment can be started for processing without checking while the equipment is in operation, thereby reducing the defect rate and further improving the processing efficiency.

[0038] Reference Figure 1 and Figure 6 The base 3 is also equipped with a welding assembly 5, which can weld the closed chain link opening to make the closure more secure. The welding assembly 5 includes a mounting base 52, a laser welding head 51, and a laser 53. The mounting base 52 is located on one side of the cutter base 32. The laser welding head 51 is mounted on the mounting base 52 and is connected to the laser 53 through an optical fiber. The base 3 has a cavity for installing the laser 53. The laser 53 is directly integrated into the base 3 during production, which makes the integration of the whole equipment higher and facilitates the subsequent handling and use of the entire chain weaving equipment, without having to install the laser 53 separately next to the base 3.

[0039] Reference Figure 6 and Figure 7 The mounting base 52 includes a base plate 521 and a vertical plate 522, which are fixedly connected. The base plate 521 is mounted on the base 3. The maximum cross-section of the vertical plate 522 is trapezoidal, and a mounting hole 523 is provided on the vertical plate 522. The maximum cross-section of the laser welding head 51 is L-shaped. The laser welding head 51 includes a welding part 511 and a connecting part 512. The welding part 511 is inserted into the mounting hole 523. An oil-blocking groove 513 is provided at the end of the connecting part 512. An optical fiber port 514 is installed in the oil-blocking groove 513. The welding part 511 is used to emit laser, and the connecting part 512 is used to connect optical fiber. The oil-blocking groove 513 can block lubricating oil stains. Installing optical fiber in the oil-blocking groove 513 can protect the signal transmission of optical fiber from the negative impact of oil stains.

[0040] Reference Figure 2 and Figure 7 An adjusting bolt 524 is installed between the base plate 521 and the vertical plate 522. The adjusting bolt 524 is threadedly connected to the vertical plate 522, and the screw of the adjusting bolt 524 passes through the side wall of the mounting hole 523 and abuts against the laser welding head 51. The adjusting bolt 524 is used to adjust the welding point position of the laser welding head 51. When it is necessary to finely adjust the welding position of the laser welding head 51, rotating the adjusting bolt 524 will cause the screw to abut against the outer wall of the laser welding head 51, so that the laser welding head 51 will rotate slightly, thereby achieving precise adjustment of the welding position without having to move the mounting base 52 significantly. Therefore, the accuracy and convenience of welding the welding assembly 5 can be improved.

[0041] The implementation principle of an integrated Chopin machine according to an embodiment of this application is as follows: the clamping rod 42 can clamp and fix the woven chain. One end of the transmission rod 43 is fixedly connected to the moving block 411, and the other end of the transmission rod 43 is in contact with the cam on the camshaft 1. Under the contact of the cam, the transmission rod 43 can drive the moving block 411 to rotate relative to the stationary block 412 along the hinge axis, completing the opening and closing action of the clamping block 41. This causes the two clamping rods 42 to move closer or further away from each other, thereby clamping and fixing the chain. This can prevent the chain from shaking significantly during movement, thus preventing the chain from falling off the upper clamping seat 2. This allows the collaborative weaving work between the upper clamping seat 2 and other devices to be carried out continuously and stably, without the need for processing personnel to monitor and correct the processing process of the equipment. The entire machine can independently complete the weaving of chain jewelry, thereby improving the automation level and processing efficiency of the Chopin machine.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
