[0029] In some embodiments, a structure of a driving mechanism is provided. Figure 1-3 As shown, the driving mechanism includes a first support column 4, a second support column 10, a screw drive motor 8, a slide 5, a first rotating shaft 11 and a screw 9. The second support column 10 is arranged in parallel with the first support column 4 and is connected through a support table 7; the screw drive motor 8 is installed on the support table 7; both ends of the slide 5 are slidably connected with the corresponding first support column 4 and second support column 10; the first rotating shaft 11 is rotatably installed on the slide 5; one end of the screw 9 passes through the slide 5, the support table 7 and is transmission-connected with the screw drive motor 8, and the other end is rotationally connected with the support 2.

[0030] A rotational mounting structure of the first rotating shaft 11 and the slide is as follows: the first rotating shaft 11 is connected to the slide 5 via a rolling bearing. The first rotating shaft 11 can rotate relative to the slide under the action of the rolling bearing.

[0031] Working method:

[0032] The screw drive motor 8 drives the screw 9 to rotate, and the screw 9 drives the slide 5 to move along the height direction of the first pillar 4 and the second pillar 10. The slide 5 drives the first rotating shaft 11 to move, and the first rotating shaft 11 drives the forming guide roller 14 installed thereon to move.

[0033] In some embodiments, a connection structure between the forming guide roller and the first rotating shaft is provided, and a sleeve 13 and a screw 12 are additionally installed. Figure 1-3 As shown, at least one screw 12 is installed on the sleeve 13, one end of which is sleeved on the first rotating shaft 11, and the other end is connected to the forming guide roller 14; the screw 12 is screwed into the sleeve 13 to be tightened against the first rotating shaft 11, so that the sleeve 13 is fixedly sleeved on the first rotating shaft 11; the screw 12 is screwed out of the sleeve 13, and the sleeve 13 is slidably connected to the first rotating shaft 11.

[0034] The number of screws 12 installed can be 1, 2 or 3 etc. Can select and install the screw of appropriate amount according to production needs.

[0035] It should be noted that the forming guide roller is installed on the first rotating shaft through a sleeve, so that the forming guide roller can be replaced. Therefore, a plurality of forming guide rollers of different diameters can be prepared to meet the needs of bending and forming rings of different diameters.

[0036] Installation method: sleeve the sleeve 13 onto the first rotating shaft 11, then screw the screw 12 into the sleeve 13 to tighten it onto the first rotating shaft 11, so that the sleeve 13 is fixedly sleeved onto the first rotating shaft 11, and the installation is completed.

[0039] The first limit sensor 3 and the second limit sensor 6 are both electrically connected to the controller 1 .

[0040] Working method:

[0041] Upward limit: When the slide 5 moves upward along the first pillar 4 and the second pillar 10, when it moves to touch the second limit sensor 6, the second limit sensor 6 immediately sends limit data information to the controller 1. When the controller receives the limit data information, it controls the screw drive motor 8 to stop working, the screw 9 stops rotating, and the slide stops moving upward.

[0042] Downward limit: When the slide 5 moves downward along the first pillar 4 and the second pillar 10, when it moves to touch the first limit sensor 3, the second limit sensor 3 immediately sends limit data information to the controller 1. When the controller receives the limit data information, it controls the screw drive motor 8 to stop working, the screw 9 stops rotating, and the slide stops moving downward.

[0043] In some embodiments, a rotating structure of a feed guide roller and an auxiliary guide roller is provided, and a support seat 16, a drive shaft 20, a driving wheel 21, a driven wheel 17 and a second rotating shaft 32 are additionally installed. Figure 1-3 As shown, one end of the driving shaft 20 is connected to the driving motor 18, and the other end is connected to the feed guide roller 22 through the support seat 16, and the driving wheel 21 is installed thereon; one end of the second rotating shaft 32 is connected to the auxiliary guide roller 15, and the other end is connected to the driven wheel 17 through the support seat 16, and the driven wheel 17 is connected to the driving wheel 21.

[0044] The drive shaft 20, the second rotating shaft 32 and the support seat 16 are all rotatably connected. The drive shaft 20 and the second rotating shaft 32 can be connected to the support seat 16 through rolling bearings respectively. The drive shaft 20 and the second rotating shaft 32 can rotate relative to the support seat under the action of the rolling bearings.

[0045] A transmission connection between the driven wheel 17 and the driving wheel 21: the driven wheel 17 and the driving wheel 21 are connected to each other through a transmission member 19. The transmission member 19 can be a transmission belt or a chain.

[0046] Working method:

[0047] The driving motor 18 drives the main driving shaft 20 to rotate, the driving shaft 20 drives the feed guide roller 22 and the driving wheel 21 to rotate, the driving wheel 21 drives the driven wheel 17 to rotate through the transmission member 19, and the driven wheel 17 drives the auxiliary guide roller 15 to rotate through the second rotating shaft 32.

[0048] In some embodiments, a structure capable of automatically feeding materials is provided. Figure 2 As shown, a conveyor, a first laser positioning sensor 24 and a second laser positioning sensor 23 are additionally installed. The conveyor is aligned with the feed guide roller 22; the first laser positioning sensor 24 is aligned with the axial top surface of the feed guide roller 22 and installed; the second laser positioning sensor 23 is placed between the feed guide roller 22 and the auxiliary guide roller 15 and installed close to the auxiliary guide roller 15; the conveyor, the first laser positioning sensor 24 and the second laser positioning sensor 23 are electrically connected to the controller 1 respectively.

[0049] Working method:

[0050] The conveyor is controlled by the controller 1 to guide the gold bar 31 to be processed thereon to the feed guide roller 22. When the gold bar 31 to be processed is transmitted to the axial top surface of the feed guide roller 22, the first laser positioning sensor 24 detects that the gold bar to be processed is transmitted to the axial top surface of the feed guide roller 22, and immediately sends a data signal to the controller 1. After receiving the data signal, the controller controls the drive motor 18 to operate, and the drive motor 18 drives the main drive shaft 20 to rotate, and the drive shaft 20 drives the feed guide roller 22 and the driving wheel 21 to rotate. The feed guide roller 22 drives the gold bar 31 to be processed into the bending space formed by the forming guide roller 14, the feed guide roller 22 and the auxiliary guide roller 15. Under the joint action of the forming guide roller 14, the feed guide roller 22 and the auxiliary guide roller 15, the gold bar to be processed is bent and sleeved on the forming guide roller 14.

[0051] At the same time, the driving wheel 21 drives the driven wheel 17 to rotate through the transmission member 19, and the driven wheel 17 drives the auxiliary guide roller 15 to rotate through the second rotating shaft 32; when the second laser positioning sensor 23 detects that the gold bar to be processed enters between the feed guide roller 22 and the auxiliary guide roller 15, it immediately sends a data signal to the controller. After receiving the data signal, the controller controls the conveyor to temporarily work and start timing, that is, stops conveying the gold bar to be processed to the feed guide roller 22.

[0052] The time setting can be 3 to 5 seconds. When the timing reaches the set time (such as 3, 4 or 5 seconds), the drive motor 18 is controlled to stop working and the screw drive motor 8 is controlled to work. The screw drive motor 8 drives the screw rod 9 to rotate, and the screw rod 9 drives the slide 5 to move upward. The slide moves until it touches the second limit sensor 6. The second limit sensor 6 immediately sends a limit data signal to the controller. The controller receives the limit data signal and controls the screw drive motor 8 to stop working. At this time, the gold ring on the forming guide roller 14 can be taken out, and the gold bar to be processed can be bent into a gold bracelet.

[0053] In some embodiments, a structure of a conveyor is provided. Figure 2 As shown, the conveyor includes a conveyor frame 26, a conveyor drive motor 29 and a motor frame 30. The two ends of the conveyor frame 26 are rotatably mounted with a driving roller 28 and a driven roller 25, and the driving roller 28 and the driven roller 25 are connected by a conveyor belt 27; the conveyor drive motor 29 is connected by a driving roller 28; the motor frame 30 is mounted on the conveyor frame 26, and is used to install the conveyor drive motor 29.

[0054] Working method:

[0055] When the conveying drive motor 29 is started, it drives the active roller 28 to rotate, and the active roller 28 drives the driven roller 25 to rotate through the conveyor belt 27. The conveyor belt 27 forms a closed rotation under the rotation of the active roller 28 and the driven roller 25, and can convey the gold bars 31 to be processed placed thereon to the feed guide roller 22.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
