Description

Technical Field

[0001] This utility model relates to the field of dental medical equipment manufacturing technology, and in particular to a wire feeding device. Background Technology

[0002] Orthodontics refers to the use of specific braces to apply force to the teeth, thereby correcting facial and jawbone developmental abnormalities and adjusting misaligned teeth. A crucial component of these braces is the archwire. As orthodontic wire, the curved archwire generates orthodontic force, prompting tooth movement and achieving the corrective effect.

[0003] Conventional orthodontic wire processing mainly relies on manual operation. Doctors use their experience and visual observation to manually bend the orthodontic wire. The precision of the wire bending plays a decisive role in the treatment effect.

[0004] However, the manual bending process is not only time-consuming and labor-intensive, but also results in significant differences in the shape of the wires bent by different doctors, making it difficult to guarantee accuracy and consistency. This directly affects the accuracy and stability of orthodontic treatment.

[0005] Although some machines can achieve a certain degree of automated bending, the orthodontic wires are fed one by one. For example, in an orthodontic archwire bending device disclosed in patent publication number CN213190206U, the feeding mechanism is similar to a linear module. An "L"-shaped baffle moves on the feeding mechanism, and one end of the archwire rests on the "L"-shaped baffle. The "L"-shaped baffle pushes the archwire to move towards the bending mechanism.

[0006] If a certain number of archwires need to be bent, the above method of delivering a single wire requires frequent manual installation of the archwires. Moreover, each person's orthodontic situation is different, so the actual archwires used may vary in length. This can result in a situation where one archwire is left over, which cannot be used and leads to waste of orthodontic wire. Summary of the Invention

[0007] To address the potential waste caused by single-strand orthodontic wire feeding, this invention provides a wire feeding device. A certain length of orthodontic wire is neatly wound onto a feeding tray. After being guided and straightened, the wire is conveyed forward. The device allows for flexible extraction of wire of the appropriate length as needed, ensuring on-demand retrieval and preventing wire waste.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A wire feeding device for conveying orthogonal wire to a bending machine includes a wire feeding platform, a feeding mechanism, a straightening mechanism, a wire feeding mechanism, and a clamping mechanism. The feeding mechanism, the straightening mechanism, the wire feeding mechanism, and the clamping mechanism are arranged sequentially on the wire feeding platform along the wire conveying direction.

[0010] The feeding mechanism includes a guide plate that is horizontally adjustable above the wire feeding platform and a feeding plate that is horizontally adjustable below the wire feeding platform, facilitating the adjustment of the positions of the guide plate and the feeding plate. The guide plate, straightening mechanism, wire feeding mechanism, and clamping mechanism are arranged in a straight line on the same plane, ensuring that the orthogonal wire is fed in a straight line. The straightening mechanism is horizontally adjustable on the wire feeding platform, facilitating the adjustment of the position of the straightening mechanism. The wire feeding mechanism and the clamping mechanism are arranged opposite to each other.

[0011] The feeding tray is wound with orthogonal wire, which is led out from the feeding tray and sequentially threaded between the guide plate, the straightening mechanism, the wire feeding mechanism and the clamping mechanism.

[0012] Furthermore, the wire feeding platform is fixedly provided with horizontally arranged optical rods, the number of which is two optical rods arranged at intervals, and one end of the optical rod extends out of the wire feeding platform.

[0013] Furthermore, a feeding plate is slidably mounted on the optical rod, and the feeding plate is connected to the optical rod via a slider with a locking function, which facilitates the sliding and locking of the feeding plate. A feeding tray is rotatably mounted below the feeding plate, which facilitates the feeding of the line by the feeding tray.

[0014] The feeding tray has an I-beam structure, with its axial direction perpendicular to the axis of the guide rod, and the feeding tray is arranged below the guide rod.

[0015] Furthermore, a guide frame is slidably mounted on the optical rod. The guide frame is connected to the optical rod via a slider with a locking function, which facilitates the sliding and fixing of the guide frame. The guide frame is equipped with a guide disc for guiding the wire, and the guide discs are arranged above the optical rod.

[0016] Furthermore, the guide disc is evenly provided with multiple guide wheel groups in the circumference, and the orthodontic wire is wound around the guide wheel groups. Each guide wheel group includes two guide wheels arranged inside and outside, and the two guide wheels clamp the orthodontic wire to facilitate the guidance and restriction of the orthodontic wire.

[0017] Furthermore, the straightening mechanism includes a straightening plate and a straightener disposed on the straightening plate for correcting the straightness of the wire. The straightening plate is slidably disposed on the optical rod, and the straightening plate is connected to the optical rod through a slider with a locking function, which facilitates the sliding and fixing of the straightening plate.

[0018] Furthermore, the wire feeding mechanism includes a linear module and a first fast-rotating chuck controlled by the linear module, which facilitates driving the fast-rotating chuck to reciprocate in a straight line. The clamping mechanism includes a second fast-rotating chuck and a wire feeding nozzle controlled by the second fast-rotating chuck.

[0019] The first and second quick-turn chucks are arranged opposite each other. The orthodontic wire passes through the first and second quick-turn chucks in sequence and is then led out by the wire feed nozzle.

[0020] The beneficial effects of this utility model through the above technical solution are:

[0021] This invention winds a certain length of orthodontic wire onto a feeding reel, avoiding the defects associated with single orthodontic wires. After the wire is drawn out from the feeding reel, it passes upwards around a guide plate and is guided into a straightener. The straightener straightens the wound wire, ensuring it remains in a straight line and improving the straightness of the orthodontic wire. The feeding and straightening mechanisms are adjustable, facilitating equipment debugging and allowing for adjustments to the installation positions to meet wire feeding requirements.

[0022] This invention achieves continuous feeding of orthodontic wire through the cooperation of a wire feeding mechanism and a clamping mechanism. The power source for feeding the orthodontic wire is the wire feeding mechanism, which drives a rapidly rotating chuck to reciprocate in a straight line via a linear module, thereby moving the wire forward and passively extracting the wire from the feed tray.

[0023] In this invention, during the wire feeding mechanism's forward movement, the clamping mechanism remains stationary, ensuring the wire passes smoothly through the clamping mechanism. When the wire feeding mechanism retracts, the clamping mechanism activates, securing the wire. Since orthodontic wires have a certain length, the wire feeding mechanism can retrieve only the required amount of wire during extraction, avoiding waste. Attached Figure Description

[0030] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0031] like Figures 1-5 As shown, a wire feeding device is used to transport orthogonal wires to a bending machine 6. The feeding device includes a wire feeding platform 1, a feeding mechanism 2, a straightening mechanism 3, a wire feeding mechanism 4, and a clamping mechanism 5. Here, the feeding mechanism 2, the straightening mechanism 3, the wire feeding mechanism 4, and the clamping mechanism 5 are arranged sequentially on the wire feeding platform 1 along the wire conveying direction.

[0032] The feeding mechanism 2 includes a guide plate 22 that is horizontally adjustable above the wire feeding platform 1 and a feeding tray 21 that is horizontally adjustable below the wire feeding platform 1. The feeding tray 21 has an I-beam structure and carries orthogonal wire on it. That is, orthogonal wire is wound on the feeding tray 21, and the feeding tray 21 collects a certain length of orthogonal wire.

[0033] During installation, the feeding tray 21 has horizontally arranged guide rods 7 on the wire feeding platform 1, with two guide rods 7 spaced apart. One end of each guide rod 7 extends out of the wire feeding platform 1. Each guide rod 7 has multiple locking sliders 8 mounted on it, located at the extended end of the guide rod 7. These sliders 8 are SCS series box-type locking linear sliders 8. The sliders 8 are existing technology; they can slide freely on the guide rods 7 and can be locked by manually adjusting the handles on the sliders 8, preventing further movement. Further details are omitted here.

[0034] A feeding plate 9 is slidably mounted on the guide rod 7. The feeding plate 9 is a plate body bent into an "L" shape and is installed upside down. The feeding plate 9 is connected to the guide rod 7 through two sliders 8 with locking function, so that the feeding plate 9 can move and lock on the guide rod 7.

[0035] A feeding disc 21 is rotatably arranged below the feeding plate 9. Specifically, a feeding spindle 10 is rotatably arranged below the feeding plate 9. The feeding spindle 10 is connected to the feeding plate 9 through a rotation damper. The feeding spindle 10 is arranged horizontally, so the feeding spindle 10 can rotate and will have a certain rotational resistance.

[0036] The feeding tray 21 is mounted on the feeding mandrel 10, and the two are fitted together to ensure the relative fixation of the feeding tray 21 and the feeding mandrel 10. Under the action of the rotation damper, the feeding tray 21 is difficult to rotate easily, thus providing a certain tension force during wire feeding. After installation, the axial direction of the feeding tray 21 is perpendicular to the axial direction of the guide rod 7, and the feeding tray 21 is arranged below the guide rod 7.

[0037] During installation, the guide plate 22 has a guide frame 11 slidably mounted on the light rod 7. The two ends of the guide frame 11 are connected to the light rod 7 through sliders 8 with locking function. The guide frame 11 can move and lock on the light rod 7.

[0038] The guide frame 11 includes two mounting blocks 111 and a support rod 112 disposed between the two mounting blocks 111. A slider 8 with a locking function is disposed below each mounting block 111. A guide plate 22 for guiding the wire is disposed on the guide frame 11, that is, the guide plate 22 is fixedly disposed on the support rod 112, and the guide plate 22 is arranged above the guide rod 7.

[0039] To prevent the wire bending radius from being too small, six guide wheel sets are evenly arranged around the guide disk 22. These guide wheel sets are located on one end face of the guide disk 22, and the orthodontic wire passes between several of these guide wheel sets. Each guide wheel set includes two guide wheels 12 arranged inner and outer, meaning the two guide wheels 12 are arranged along the diameter of the guide disk 22. The distance between the two guide wheels 12 and the center of the guide disk 22 is different, and the orthodontic wire is held between the two guide wheels 12. The guide wheels 12 are V-grooved wheels.

[0040] In this embodiment, the guide plate 22, the straightening mechanism 3, the wire feeding mechanism 4, and the clamping mechanism 5 are arranged in a straight line on the same plane. During installation, the straightening mechanism 3 is also horizontally adjustable on the wire feeding platform 1. Specifically, the straightening mechanism 3 includes a straightening plate 31 and a straightener 32. The straightener 32 is mounted on the straightening plate 31 and is used to correct the straightness of the wire.

[0041] A straightening plate 31 is slidably mounted on the optical rod 7. The straightening plate 31 is bent into an "L" shape. The straightening plate 31 is connected to the optical rod 7 through four sliders 8 with locking function. Thus, the straightening plate 31 can move and be fixed on the optical rod 7, and simultaneously drive the straightener 32 to move and be fixed.

[0042] The wire feeding mechanism 4 and the clamping mechanism 5 are arranged opposite to each other. The wire feeding mechanism 4 includes a linear module 41 and a fast-rotating chuck 42 controlled by the linear module 41. The linear module 41 adopts an electric lead screw module. The fast-rotating chuck 42 is installed on the linear module 41, which can drive the fast-rotating chuck 42 to reciprocate linearly.

[0043] The structure and operating principle of the quick-rotating chuck 42 are existing technologies. The pneumatic gripper can clamp the wire and ensure sufficient friction between the pneumatic gripper and the orthodontic wire to avoid slippage during the wire feeding rotation. It is also equipped with a servo motor, which drives the pneumatic gripper to rotate. This will not be described in detail here.

[0044] The clamping mechanism 5 includes a second rapid-return chuck 51 and a wire feeding nozzle 52 controlled by the second rapid-return chuck 51. The second rapid-return chuck 51 has the same structure and operating principle as the first rapid-return chuck 42. The first rapid-return chuck 42 and the second rapid-return chuck 51 are arranged opposite each other, and the second rapid-return chuck 51 drives the wire feeding nozzle 52 to rotate together. The wire feeding nozzle 52 is a hollow stepped cylindrical structure.

[0045] After being drawn out from the feed tray 21, the orthodontic wire is sequentially threaded between the guide plate 22, the straightening mechanism 3, the wire feeding mechanism 4, and the clamping mechanism 5. The orthodontic wire passes through the first rapid rotary chuck 42 and the second rapid rotary chuck 51 in sequence, and is then led out by the wire feeding nozzle 52.

[0046] The principle of this invention is as follows: Orthodontic wire is made of steel wire. The orthodontic steel wire is led out from the feeding tray 21 and first wound around several guide rollers to ensure that the steel wire between the feeding tray 21 and the guide tray 22 has a large arc bend, ensuring that the steel wire entering the straightener 32 will not undergo plastic deformation. Then it passes through the straightener 32 to straighten the steel wire, and then passes through the quick-return chuck 1 42 and quick-return chuck 2 51 in sequence, and is guided to the bending machine 6 by the wire feeding nozzle 52. The wire feeding mechanism 4 and the clamping mechanism 5 are controlled to operate in coordination according to actual needs to realize the conveying of the orthodontic steel wire to the bending machine 6.

[0047] During the actual conveying process, the rapid rotary chuck 42 clamps the steel wire, and the linear module 41 starts, driving the rapid rotary chuck 42 to move forward at a set speed, pulling the steel wire out of the feeding tray 21. At the same time, the rapid rotary chuck 42 rotates, causing the orthodontic steel wire to move forward continuously during the rotation, maintaining the steel wire being conveyed forward at a stable speed. During this forward wire feeding process, the clamping mechanism 5 does not operate.

[0048] It is important to note that the wire feeding mechanism 4 and the clamping mechanism 5 are two separate, complementary mechanisms. That is, when the wire feeding mechanism 4 moves forward to feed the wire, the clamping mechanism 5 releases, ensuring the orthodontic wire passes smoothly through it. When the wire feeding mechanism 4 retracts, it stops clamping the wire, while the clamping mechanism 5 clamps the wire to ensure it is secure. The wire feeding operation is completed through the cooperation of these two different mechanisms.

[0049] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
